Description

Pants

Technical field

The present invention relates to a kind of pants, be used for using sanitary napkin, relate in particular to a kind of pants of thick sanitary napkin to prevent to be shifted that can firmly keep the use at night at crotch's dress, its fitness excellence, and can not cause the uncomfortable feeling that fetters wearer's body substantially.

Background technology

Sanitary napkin on the crotch part that need utilize pants reliably and securely to remain attached to be positioned at pants divides is shifted in crotch to prevent sanitary napkin, in addition by reducing piercing comfortable sensation to the wearer is provided health crotch.

As such pants, (in JP-2001-522958A) disclosed a kind of like this pants, it forwardly and have the big part of tension load ability to bear in the middle section between the rear portion, between front and rear and connect the crotch part branch of front and rear and a pair of shank elastic opening.Several stretching control assemblies that this pants have the longitudinal stretching control assembly that is arranged in the crotch area and are arranged in front and rear and extend to waistband from the longitudinal stretching control assembly.The present inventor provides a kind of comfortable pants, and it can easily be adorned sanitary napkin and be used in crotch, prevents that sanitary napkin is drilled into (JP-A-2002-660) in the crotch.This pants comprise around the waistband of waist opening and around the bottom bands of trouser legs of leg opening, and with the crotch of the part that connects sanitary napkin.These pants are characterised in that, when as three-dimensional dimension shape condition when wearing under in the measurement size, if with central authorities' height length is 100, then from crotch to waist opening the central length of part with the dimension scale between partly the side edge length is from leg opening to waist opening, side height length and partly is provided with the elasticity lifting piece from crotch to waist opening in the rear portion in the scope of 80-200.

But according to the pants that in JP-T-2001-522958, disclose, although placing the sanitary napkin of crotch area to adorn securely by the stretching control assembly is used on the health, but because the stretching control assembly is set to fillet, therefore force localization is on linearity point, so pants may be drilled in the health under the condition of wearing.In addition, sanitary napkin may form projection upwards in the centre bending, so curved top portion bring uncomfortable feeling may for wearer's health.

In addition, owing to form two elastic leg openings by front and rear is sewed up, sutured portion is extended in the central authorities that crotch part divides, thereby connects two leg openings.Therefore when sanitary napkin is connected on the pants, do not have to keep securely the basis of sanitary napkin, therefore, the bonding portion that may be twisted into narrow shape or sanitary napkin because of sanitary napkin is peeled off and is caused leakage from the pants main body.

According to the pants that disclose in JP-A-2002-660, the elasticity lifting piece that is arranged on the rear portion extends along the longitudinal, and produces the resilience convergent force.This resilience convergent force along spinal cord then along thigh ditch and crotch in the substantially linear effect of the central portion office at rear portion.Therefore produce big castering action power in the crotch part office, thereby the sanitary napkin that crotch part is divided is pressed onto introitus along fore-and-aft direction.

The structure of this pants is that the elasticity lifting piece that is arranged on the rear portion extends along the longitudinal, and therefore generation is used for sanitary napkin is adorned the elasticity castering action power that is used on the health.But because the elasticity lifting piece is arranged on the rear portion, the front portion forms by having abundant flexible fabric, therefore when the thick sanitary napkin of ight is connected to pants, because the elasticity lifting piece can be owing to the thickness and the high degree of rigidity of sanitary napkin are extended, sanitary napkin can fully not fit buttocks or crotch, therefore even promote and when making it conform to health, also can the suitable power of playing a role not promote sanitary napkin by being arranged on elasticity lifting piece on the rear portion at sanitary napkin.

Therefore between sanitary napkin and health, produce the slit, so menses may flow down and leak out along dorsal part from sanitary napkin.In addition, menses may be sprawled by the slit and come, and have increased the contact area of skin and menses, and this can bring skin big burden, may cause allergic.

If for example because be used for preventing the wearer in sleep, unconsciously move in sanitary napkin move or twist waistband compressing health the time, may cause expanding or the hematogenous disorder owing to the tensioning that brings very big stress to health.

Therefore need a kind of pants, it can not oppress whole health, but can be only with the necessary position compression fit of sanitary napkin on health.

Summary of the invention

An object of the present invention is to provide a kind of sanitary napkin, it can easily be adorned the thick sanitary napkin of ight and use to crotch or strand ditch, prevents its displacement, and prevents that it is drilled in the crotch, can bring a kind of comfortable sensation, not have constraint wearer's uncomfortable feeling.

In view of the problems of the prior art, the invention provides a kind of pants, high flexibility parts that it forms by the material that provides by the height elasticated and form by the slight elastomeric element that the material of slight elasticated forms, and have the crotch part branch of bridge joint front and rear.Slight elastomeric element is arranged on from crotch part branch rear end to the middle section at the rear portion of waist retaining part.The longitudinal elastic coefficient of slight elastomeric element is than the longitudinal elastic coefficient height of the high flexibility parts of buttocks that covers its central area and belly.Be arranged on the middle part that crotch part divides with the sanitary napkin lift portion that the slight elastomeric element at rear portion is sewed up mutually, its longitudinal elastic coefficient is higher than the longitudinal elastic coefficient that constitutes the crotch's fabric that covers crotch area crotch part branch on every side.Utilize said structure, finish the present invention, and can address the above problem.

In particular, the invention provides:

(1) a kind of pants, the slight elastomeric element that high flexibility parts that it forms by the material that provides the height elasticated and the material that slight elasticated is arranged form forms, and comprising:

Anterior; The rear portion; The crotch part branch of bridge joint forwardly and between the rear portion; Waist opening part in the top edge at fore top edge and rear portion is set; And a pair of leg opening under the both sides of the edge at fore both sides of the edge and rear portion is set, the belt-like zone that wherein is arranged on the basic middle section at the rear portion of part from the crotch part branch to waist opening is formed by described slight elastomeric element.

According to the present invention, when the pull-up pants wore, the slight elastomeric element that is configured in the belt-like zone from the crotch part branch to waist was used for that connected crotch part branch is not being had pull-up under the situation of extending.Therefore will be connected on sanitary napkin pull-up that crotch part divides and the crotch that is contained in health or on strand ditch, and be difficult to thus between sanitary napkin and health, produce the gap, prevent that therefore menses from leaking.Therefore because pants are to make with the high flexibility parts that the height elasticated is arranged, wear comfortable and can not resemble and give the uncomfortable sensation of wearer's whole health the waistband with constraint.Since the crotch part branch of when wearing pants, being arranged to the bridge joint front and rear be positioned at pubis and anus back part around, therefore when being connected with the pants of sanitary napkin on its crotch part branch of user wears, sanitary napkin can stably be connected to crotch part and divide, thereby prevent that sanitary napkin from reversing, avoid the leakage of menses thus.

" front portion " means that the pants body covers the previous section of belly herein, and on behalf of the pants body, " rear portion " cover the aft section of waist rear side." pants body " means the part that covers the health waist." the crotch part branch is arranged to forwardly and bridge joint between the rear portion " means by modes such as stitchings crotch's fabric is connected to the crotch part branch that front and rear forms, be not that front and rear is directly connected.

(2) the invention provides a kind of as (1) described pants, the longitudinal elastic coefficient of its mild or moderate elastomeric element is greater than the longitudinal elastic coefficient of high flexibility parts.

According to the present invention, when the wearer sanitary napkin is connected to sanitary napkin dress with fabric on and with pants on draw when wearing, slight elastomeric element is upwards drawn, crotch part divide and slight elastomeric element between the part sewed up become the strong point.Then, be used for the active force that slight elastomeric element upwards draws is become the active force that the crotch part branch is upwards drawn and will be connected to the active force of sanitary napkin dress with the suspention of the overnight hygienic band on the fabric.In this case, because the longitudinal elastic coefficient of slight elastomeric element is bigger than the longitudinal elastic coefficient that is arranged on the high flexibility coefficient around the slight elastomeric element, therefore is used for active force with the sanitary napkin suspention and is effective as the active force that sanitary napkin that the crotch part that will be connected to slight elastomeric element divides and be connected to this crotch part to divide upwards draws.Therefore, different with the middle section place rubber-like pants at rear portion in the prior art, promptly, even pants of the prior art the wearer by keeping the waist opening part when drawing on pants, also only there is the middle section at rear portion to extend, can not bring into play the sufficient active force that sanitary napkin is upwards drawn, and pants of the present invention can easily be used the thick sanitary napkin dress of ight to crotch or strand ditch.

Preferably, the longitudinal elastic coefficient of slight elastomeric element is greatly about 10N-60N, more preferably at 20N-50N.When coefficient of elasticity less than 10N the time, the active force of suspention sanitary napkin is not enough, therefore can not be effectively as the active force that suspends sanitary napkin in midair.In this case, when the wearer upwards drew pants, slight elastomeric element excessively extended, so the active force that the wearer applies can be effectively as the active force that sanitary napkin is upwards drawn.Coefficient of elasticity is not preferred greater than 60N, because be easy to produce than dress with the big upper pulling force of sanitary napkin necessary forces, so sanitary napkin surpasses somagenic need and pierce in the health, and this can cause uncomfortable or pain.For example, it is not preferred self not having flexible materials such as plastics band or rope because it make draw pants active force directly as on draw the active force of sanitary napkin, therefore make sanitary napkin pierce too far in the gap of health.

Slight elastomeric element vertically and the high flexibility parts vertically corresponding to when wearing, will drawing on the pants or drop-down direction (the Y direction among Fig. 1 and Fig. 2) and direction from crotch part branch and leg opening towards waist.Crotch means the part between the shank of health, comprises for example part of introitus, perineum and anus.Coefficient of elasticity means by the tension load that will draw on the parts of pants (slight elastomeric element, high flexibility parts, sanitary napkin lift portion and fixed part) and apply when extending divided by at that time the value that stretch ratio obtained, coefficient of elasticity is big more, and the possibility of stretching is more little.

(3) the invention provides a kind of pants, comprise the front portion; The rear portion; Be provided for forwardly and the crotch part branch of bridge joint between the rear portion, this crotch part branch is used for the dress sanitary napkin; Waist opening part in the top edge at fore top edge and rear portion is set; And a pair of leg opening under the both sides of the edge at fore both sides of the edge and rear portion is set, wherein the middle part that the crotch part from front portion to rear portion divides the sanitary napkin lift portion is set, the longitudinal elastic coefficient of this sanitary napkin lift portion is greater than the longitudinal elastic coefficient of the fabric that constitutes the crotch part branch.

According to the present invention, because the longitudinal elastic coefficient of sanitary napkin lift portion is greater than the longitudinal elastic coefficient of crotch's fabric on every side, so by will drawing on the sanitary napkin lift portion than the big active force of active force that will draw on the fabric on every side, this produces an active force that will be connected to sanitary napkin middle body (towards the crotch of the health) lifting of crotch part branch.The flexible coefficient of elasticity of sanitary napkin lift portion is preferably 5N-30N, more preferably 10-25N.When coefficient of elasticity less than 5N the time, the active force of suspention sanitary napkin middle body can effective function with respect to the upper pulling force of slight elastomeric element.As described in (1), because the crotch part branch is set to forwardly and bridge joint between the rear portion, so it is wearing state inside around pubis and anus aft section.Therefore when the wearer was connected to sanitary napkin that crotch part divides and pants are put on, sanitary napkin can stably be connected to the crotch part branch, therefore prevents that sanitary napkin from reversing, and avoids the danger of menses leakage thus.When be provided with on the inboard that is constituting crotch's fabric that crotch part divides have the waterproof fabric of water resistance in, waterproof fabric can with crotch's fabric and anterior or with crotch's fabric and rear portion along with crotch's fabric and anterior or and the sutured portion that is stitched together of rear portion be stitched together.Therefore can not increase the quantity of sutured portion, therefore can prevent uncomfortable feeling or damage outward appearance in the state of wearing.Direction during sanitary napkin lift portion vertical between front and rear.

(4) the invention provides a kind of pants, comprise the front portion; The rear portion; Be provided for forwardly and the crotch part branch of bridge joint between the rear portion, this crotch part branch is used for the dress sanitary napkin; Waist opening part in the top edge at fore top edge and rear portion is set; A pair of leg opening under the both sides of the edge at fore both sides of the edge and rear portion is set, and be arranged on the slight elastomeric element of making by the material in the high flexibility parts made of material with height elasticated by having slight elasticated, its mild or moderate elastomeric element is arranged on the basic middle section at the rear portion of part from crotch to waist opening, the sanitary napkin lift portion is arranged on from the middle part that the crotch part at front portion to rear portion divides, slight elastomeric element and sanitary napkin lift portion are stitched together at the place, end that crotch part divides on the side at rear portion, the longitudinal elastic coefficient of slight elastomeric element is greater than the longitudinal elastic coefficient of high flexibility parts, and the longitudinal elastic coefficient of sanitary napkin lift portion is greater than the longitudinal elastic coefficient of the fabric that constitutes the crotch part branch.

According to the present invention, as described in above-mentioned (2) and (3), when wearing pants, with the active force that draws on the slight elastomeric element as the active force that will draw on the sanitary napkin lift portion.Utilize the big active force of active force that draws on the fabric that divides than crotch part around will constituting to draw on the sanitary napkin lift portion, this active force is as the make progress active force of (towards the crotch part branch of health) lifting of the middle body that will be connected the sanitary napkin that crotch part divides.Therefore, sanitary napkin is fixed, thereby better is suitable for crotch.As described in (1) because the crotch part branch is set to forwardly and bridge joint between the rear portion, it wear be positioned under the state pubis and anus aft section around.Therefore when being connected with the pants of sanitary napkin on its crotch part branch of user wears, sanitary napkin can stably be connected to crotch part and divide, and therefore prevents that sanitary napkin from reversing, and avoids the leakage of menses thus.

(5) the invention provides a kind of as (1) to (4) each described pants, wherein form the crotch part branch by crotch's fabric is sewed up with the front portion with the rear portion.

According to the present invention, sutured portion is present between the front end of anterior lower end and crotch's fabric respectively and between the rear end of the lower end at rear portion and crotch's fabric, is not present in the mid portion of the width (facing the direction of a pair of leg opening) that crotch part divides.In other words, each sutured portion be positioned at pubis under the state of dress and anus aft section around.Therefore when being connected with the pants of sanitary napkin on its crotch part branch of user wears, sanitary napkin can stably be connected to crotch part and divide, and therefore prevents that sanitary napkin from reversing, and avoids the leakage of menses thus.

(6) the invention provides a kind of as (1) to (5) each described pants, its mid length shorts also comprises the waist retaining part that is arranged on around the waist opening part of extending to the front portion from the rear portion.

According to the present invention, the waist retaining part will on draw slight elastomeric element active force and with the fixed part of pants laterally (along width) fixing active force disperse, and this active force remained on waist, pants are being assemblied on the loose zone around the waist.

(7) the invention provides a kind of as (1) to (6) each described pants, its mid length shorts is included in the fixed part that is arranged in anterior basic middle section that is sewn on the outside of high flexibility parts on crotch part branch, waist retaining part and the high flexibility parts.

According to the present invention, when wearing pants by on the active force that slight elastomeric element had that the draws time towards rear portion pulling sanitary napkin lift portion, fixed part can be controlled the extension of high flexibility parts.Therefore, because the part that the sanitary napkin lift portion is provided with on the fore side is fixed, and can not be pulled because of the influence of sanitary napkin lift portion and slight elastomeric element, therefore the active force that is used to spur slight elastomeric element directly as on draw the active force of sanitary napkin lift portion, therefore on health, draw sanitary napkin, and it better is assemblied in crotch and strand ditch.

(8) the invention provides a kind of as (1), each described pants of (2) or (4)-(7), its mild or moderate elastomeric element by along the longitudinal not the rubber-like material form.

According to the present invention because slight elastomeric element does not have elasticity along the longitudinal substantially, draw with fabric and on when wearing pants when the wearer is connected to overnight hygienic band the sanitary napkin dress, on draw active force to be effective as the active force of suspention sanitary napkin.The slight elastomeric element that herein can adopt is that for example nylon fiber or polyester fiber comprise there is not for example fabric that forms of the braided fiber of polyurethane fiber of flexible parts along the longitudinal, have because the slight elasticity that the variation of braiding structure causes does not still have the elasticity that produces because of the characteristic of parts.

(9) the invention provides a kind of as each described pants of (3)-(8), wherein the sanitary napkin lift portion is by there not being flexible material to form along the longitudinal.According to the present invention, because the sanitary napkin lift portion does not have elasticity along the longitudinal substantially, therefore draw on pants when wearing as the wearer, by than acting on the bigger upper pulling force pulling sanitary napkin lift portion of transmitting from slight elastomeric element of active force around the fabric, and this upper pulling force is as the active force that promotes the sanitary napkin middle body.The sanitary napkin lift portion of Cai Yonging is that nylon fiber or the polyester fiber that for example is used for slight elastomeric element comprises there is not for example fabric of the braided fiber formation of polyurethane fiber of flexible parts along the longitudinal herein, have because the slight elasticity that the variation of braiding structure causes does not still have the elasticity that produces because of the characteristic of parts.

(10) the invention provides a kind of as (3) to (9) each pants, wherein the longitudinal elastic coefficient of sanitary napkin lift portion is less than the longitudinal elastic coefficient of slight elastomeric element.

When wearing pants, the slight elastomeric element at rear portion is used for sanitary napkin is assemblied in health, extends the sanitary napkin lift portion that crotch part divides simultaneously.Under the situation of longitudinal elastic coefficient greater than the longitudinal elastic coefficient of slight elastomeric element of sanitary napkin lift portion, when on when drawing pants, the sanitary napkin lift portion can not extended, therefore and the slight elastomeric element at rear portion can extend, and is difficult to apply the active force that makes that sanitary napkin draws on the health.

(11) the invention provides a kind of as (3) to (10) each pants, wherein the width of sanitary napkin lift portion from the front portion backward portion be tapered.

According to the present invention, by the active force that will draw on the slight elastomeric element sanitary napkin lift portion is drawn towards the rear portion, and produce the active force of (towards the crotch of health) suspention that sanitary napkin is made progress, thus the gap of bridge joint health.In this case, because the width of sanitary napkin lift portion is from being tapered towards the part of introitus, perineum and anus with the anterior part that is connected (with the contacted part of part around the pubis) beginning as this sanitary napkin lift portion of the wideest part, therefore the active force that makes progress applies with respect to part on every side along the center line of the sanitary napkin that is connected the crotch part branch.When fixed part becomes same widths with the width of the anterior part that is connected is basic with the width of crotch, stablized and the pubis contacted pants part of part on every side, and this part of pants can be centered on the introitus part on every side then.Narrowed width on the fixed part side is not preferred as perineum or circumanal part, because the center of sanitary napkin may move wearing under the state, and therefore removes from the center of introitus.

The width of this sanitary napkin lift portion can be from being tapered towards the part around introitus and the perineum with the anterior part that is connected (with the contacted part of body part around the pubis) beginning as the fixed part of wide part, and the part around the introitus is towards circumanal part broaden gradually (still than narrow with the width of the part of fixed part stitching) then.

(12) the invention provides a kind of as (11) described pants, wherein the width of sanitary napkin lift portion is at 20mm to 60mm.

According to the present invention, because the width of sanitary napkin lift portion is not a narrow line, so active force is not concentrated on the single point.Therefore, can reduce sanitary napkin is connected to sanitary napkin dress with fabric on the time sanitary napkin wearing and piercing health or crooked and folding and form and raise up and crooked napex is given the possibility of wearer's body with uncomfortable feeling under the state in centre.

(13) the invention provides a kind of as (7) to (12) each described pants, wherein the longitudinal elastic coefficient of fixed part is greater than high flexibility parts coefficient of elasticity along the longitudinal.

According to the present invention, forwardly the fixed part of central authorities produces the active force that is used for fixing with the contacted pants part of pubis part on every side.But, because the longitudinal elastic coefficient of fixed part, has just been controlled anterior extension along the longitudinal greater than the longitudinal elastic coefficient of high flexibility parts.Because fixed part is controlled this extension, anterior middle section can not extend because of the influence of slight elastomeric element or sanitary napkin lift portion, has therefore fixed sanitary napkin and the contacted part of pubis.The longitudinal elastic coefficient of fixed part is at 10N-30N, more preferably at 15N-25N.This is because anterior corresponding with belly in part because moving of health and the very big part of distortion, thus when its when inductile fabric forms at all, the waist that is positioned at the nock place has been lost character next to the shin thus to lower slider.The strong net that fixed part is made of nylon fiber and polyurethane fiber (power net) forms.

Herein fixed part vertically mean the direction of drawing on being with drop-down pants wearing, just, divide the direction to leg opening towards waist (the Y direction Fig. 2) from crotch part.

(14) the invention provides a kind of as (1), (2) or (4) to (13) in each described pants, its mild or moderate elastomeric element is sewed up with basic V font at the upper end and the waist retaining part of waist opening part one side.

According to the present invention, the length between the fabric that constitutes slight elastomeric element divides from the waist retaining part to crotch part makes and is sewed with length that center (central point of V font) to the crotch part of waist retaining part divides less than its left end and right-hand member from the V font.Since when fabric extends at the elongation at the short part of fabric place greater than elongation at its long part place, therefore when drawing on the slight elastomeric element, the part of dividing from V font center to crotch part is drawn by the active force bigger than the active force that is applied to left end and right-hand member.Therefore middle body can not relax, and therefore produces the active force that draws on the sanitary napkin.

(15) the invention provides a kind of as (6) to (13) each described pants, wherein upper end and the waist retaining part of fixed part on waist opening part one side sewed up with basic V font.

According to the present invention, the length between the fabric that constitutes fixed part divides from the waist retaining part to crotch part makes the length of central authorities (summit of V font) of fixed part less than its left end and right-hand member.Since when extending at the elongation at the short part of fabric place greater than elongation, therefore when drawing on the fixed part, by than drawing on the big middle body of active force of the active force that is applied to left end and right-hand member with fixed part at its long part place.Therefore middle body can not relax, and therefore produces the active force that draws on the sanitary napkin.

(16) the invention provides a kind of as (1) to (15) each described pants, wherein the crotch part branch comprises inboard sanitary napkin dress fabric, the sanitary napkin dress is stitched together with the front-end and back-end and the crotch part branch of fabric, and the sanitary napkin dress is not stitched together with the crotch part branch with the side of fabric.

According to the present invention, sanitary napkin dress only divides with crotch part in front-end and back-end with fabric to be sewed up, and does not divide with crotch part not to be integral fully, and it is independently to open with the crotch part branch on the inboard of crotch part branch.Therefore owing to dividing with crotch part with fabric, do not extend by the sanitary napkin dress along fore-and-aft direction (along direction) towards front and rear, even perhaps when it extends, elongation also is very little, therefore remains attached to the sanitary napkin on it reliably.In addition, because it divides stitching in front-end and back-end and crotch part, so it can be stitched together with the crotch's fabric that constitutes the crotch part branch.Therefore can not increase the quantity of sutured portion, therefore can prevent uncomfortable feeling or infringement outward appearance under the state of wearing.Front-end and back-end mean that sanitary napkin dress is with the fabric end on a side and rear portion one side forwardly.

(17) the invention provides a kind of as (16) described pants, wherein the sanitary napkin dress is equal to, or greater than the length of the crotch's fabric that constitutes the crotch part branch with the length of fabric.

According to the present invention, even the crotch part that is formed by crotch's fabric of elastomer when drawing pants on the wearer so that putting on divides when extending, because the sanitary napkin dress does not extend with the length long enough of fabric, even perhaps in the time of its extension, its elongation is very little, therefore can keep sanitary napkin reliably.When crotch part divides extension, promote the sanitary napkin lift portion towards crotch, therefore promote sanitary napkin towards crotch.

(18) the invention provides a kind of as (1), each described pants of (2) or (4) to (17), wherein the boundary between high flexibility parts and slight elastomeric element reduces elasticity from the high flexibility parts gradually towards slight elastomeric element.

According to the present invention, owing to reduce elasticity gradually, therefore draw in row on pants when wearing as the wearer from the high flexibility parts, slightly the extension of elastomeric element reduces gradually, so can fit wearer's health of pants, can not bring uncomfortable feeling.

(19) the invention provides a kind of as (1), each described pants of (2) or (4) to (17), the boundary between high flexibility parts and slight elastomeric element wherein, discontinuous variation takes place from the high flexibility parts towards slight elastomeric element in elasticity.

Elasticity by slight elastomeric element is set to slight elastomeric element discontinuous variation take place from the high flexibility parts, and high flexibility parts and slight elastomeric element obviously separate.Compare with the situation (just elasticity takes place to change continuously) that they obviously do not separate, fit performance may reduce, but has strengthened the effect that promotes sanitary napkin.

(20) the invention provides a kind of as (1) to (19) each described pants, be under the situation of three-dimensional structure wherein at pants, from crotch part divide to central authorities' height length of waist opening part be 100 with being set to the former as the dimension scale between partly the sidepiece height length from leg opening to waist opening of shortest length, the latter is between 80-200.

According to the present invention, because the sidepiece height length of pants is long, the bottom bands of trouser legs that is arranged on the leg opening place can not strained from the part around the crotch to side seam (side bone), but can strain wearer's femur zone.Therefore since the inclination that the bottom bands of trouser legs produced on draw active force can not act on crotch part to divide, therefore can not be drilled in the crotch.In addition, drew active force can not act on crotch part on big to divide because the bottom bands of trouser legs produces, therefore the upwards suspention of sanitary napkin that reliably crotch part is divided by the slight elastomeric element that is arranged on the rear portion realizes fit more thus.

(21) the invention provides a kind of as (1) to (20) each described pants, its mild or moderate elastomeric element, sanitary napkin lift portion and waist retaining part have tone or the color and luster different with the high flexibility parts.

According to the present invention,, therefore can with the naked eye be distinguished because slight elastomeric element, sanitary napkin lift portion and waist retaining part have color or the texture different with the high flexibility parts.By this way, because waist retaining part, slight elastomeric element and sanitary napkin lift portion are significant, so the wearer can identify this three parts easily, and can realize the effect of lifting piece easily.Have the outward appearance different owing to be arranged on these lifting pieces of pants central authorities with other fabric part, therefore when the wearer connects sanitary napkin and is positioned on the pants, can be easy to central authorities and pants center aligned, so the central authorities of sanitary napkin can suitably be assemblied in the central authorities of the crotch of health with sanitary napkin.Therefore, can improve the obstruction gap and prevent for example effect of the leak of liquid of menses.

(22) the invention provides a kind of as (1) to (21) each described pants, be included in the instruction that how demonstration wears on front portion or the rear portion.

According to the present invention, the wearer can control the fit performance of sanitary napkin by reading instruction.The wearer is connected to sanitary napkin dress on the pants with on the fabric by adhesive etc. with sanitary napkin, and the upper lateral part by keeping pants in last drawing draws on pants, and pants are worn assigned address to health.This mode that wears can provide to a certain degree bonding for sanitary napkin.But because everyone required bonding degree is different, those wish fit more people can by follow instruction for example " by can be fit more " with the part pulling on the extension of the slight elastomeric element of rear portion centre can realize that they are needed bonding.In this manner, guide those to wish highly bonding people, thereby can recognize how to wear easily.

(23) the invention provides a kind of as (22) described pants, wherein on slight elastomeric element, instruction partly is set near waist opening.

According to the present invention, can be by the part of last pull instruction so that sanitary napkin is better fit.In other words, when wearing pants, draw slight elastomeric element on by operation part is spurred more up by the upper lateral part that keeps pants.By drawing on the slight elastomeric element, can promote sanitary napkin more securely towards the crotch of health, as mentioned above, therefore can obtain better bonding.

Shown in Fig. 1 to 4, that pants 10 have is anterior 11, rear portion 12, anterior 11 and rear portion 12 between crotch part divide 13.Forwardly form waist opening part 14 in the top edge at 11 top edge and rear portion 12, forwardly 11 and rear portion 12 under form a pair of leg opening 15.The sanitary napkin dress that divides 13 inboard to be provided with to connect sanitary napkin on it at crotch part is with fabric 16 (see figure 8)s.Round waist opening part 14 the waist retaining part 17 that extends to rear portion 12 from front portion 11 is set.12 middle section place is provided with from crotch part and divides the 13 slight elastomeric elements 18 to 17 extensions of waist retaining part at the rear portion.High flexibility parts 19 are arranged in all other zones except waist retaining part 17 and fixed part 20 at front portion 11 and rear portion 12, and forwardly 11 basic centre is sewed up.The part high flexibility parts 19 that are arranged in the rear portion 12 form from slight elastomeric element 18 to the anterior 11 rear side high flexibility parts 19b that extend.The other parts that are arranged in anterior 11 of high flexibility parts 19 form front height elastomeric element 19a.Forwardly in 11 the middle section, fixed part 20 is set, fixed part 20 is sewed up with high flexibility parts 19.High flexibility parts 19 also with crotch part divide 13 and waist retaining part 17 forwardly 11 and rear portion 12 in sew up.In the crotch part of slight elastomeric element 18 of bridge joint and fixed part 20 divides 13 middle part, sanitary napkin lift portion 21 is set.Waistband 22 along forwardly 11 and the top edge at rear portion 12 in the upside setting of the waist retaining part 17 that forms, the bottom bands of trouser legs 23 is provided with around leg opening 15.When being 100 with central authorities height length, from crotch part divide 13 to the height length L a of central authorities of waist opening part 14 and as the dimension scale between the side height length L b from leg opening 15 to waist opening part 14 of shortest length between 80 to 200.

High flexibility parts 19 can be formed by braided fiber, for example are the combinations of nylon fiber and polyurethane fiber, the perhaps combination of polyester fiber and polyurethane fiber, the perhaps combination of nylon fiber, polyester fiber and polyurethane fiber.Also can use other braided fiber outside the above-mentioned combination, as long as its coefficient of elasticity is no more than 10N.Crotch part divides 13 by providing crotch's fabric 24 to form, and crotch's fabric 24 and high flexibility parts 19 are forwardly sewed up on the side on 11 the side and rear portion 12.Crotch's fabric 24 is similar with high flexibility parts 19, but the braided fiber by elastic stretching forms, for example be the combination of nylon fiber and polyurethane fiber, the perhaps combination of polyester fiber and polyurethane fiber, the perhaps combination of nylon fiber, polyester fiber and polyurethane fiber.The waistband 22 that is provided with along waist opening part 14 and the bottom bands of trouser legs that is provided with along leg opening 15 23 are formed by elastomeric material, for example the elastic fabrics of polyurethane fiber, synthetic rubber sheet or natural rubber sheet.Vertically mean the direction (the Y direction among Fig. 1) when waist opening part 14 and crotch part divide 13 to be restricted to upside and downside herein, just, draw direction on when wearing pants with drop-down pants 10, laterally mean and the vertically direction (directions X among Fig. 1) of quadrature, the just width of pants 10.

Waist retaining part 17 is in the formation on every side of the waist opening part 14 of pants 10, and to form the V glyph edges, pointed edge is pointed to the center at front portion 11 and rear portion 12, and the high flexibility parts 19 at this waist retaining part and front portion 11 and rear portion 12 are sewed up.Waist retaining part 17 is braided fabrics, and its coefficient of elasticity along the longitudinal is higher than coefficient of elasticity transversely.Braided fiber is for example combination of nylon fiber and polyurethane fiber, the combination of polyester fiber and polyurethane fiber, the perhaps combination of nylon fiber, polyester fiber and polyurethane fiber.Being arranged on waist opening part 14 waistband 22 on every side is polyurethane tape, natural rubber band or the synthetic rubber band of for example about 10mm, sews up with waist retaining part 17 under the state that extends.

Waist retaining part 17 is used to disperse by drawing the active force of sanitary napkin lift portion 21 on slight elastomeric element 18 or the fixed part 20, and this active force remained on waist, therefore wish the longitudinal extension of restriction waist retaining part 17, thus when wearing pants 10 with 17 maintenances of waist retaining part be fixed on waist.Wish the transverse elasticity coefficient of its transverse elasticity coefficient,, and prevent that therefore pants 10 from gliding because the active force of restriction waist opening part 14 increases greater than high flexibility parts 19.

Slight elastomeric element 18 is arranged in the basic middle section at rear portion 12.The upper end of slight elastomeric element 18 and the middle body of waist retaining part 17 (near the part the pointed edge of V glyph edges) stitching, the lower end of slight elastomeric element 18 and crotch part divide 13 the end on 12 1 sides of rear portion (crotch part divides 13 rear end) stitching, and the both side ends of slight elastomeric element 18 and high flexibility parts 19 are sewed up.Slight elastomeric element 18 extends to crotch part from waist retaining part 17 and divides 13 rear end, and divides 13 rear end to be tapered towards crotch part.The width of narrow part is 10mm to 30mm, preferably approximately is 20mm.Slight elastomeric element 18 is 30mm to 130mm with the width of the wide part that waist retaining part 17 is sewed up, and preferably approximately is 60mm.Slight elastomeric element 18 can extend to waist opening part 14.

The length (corresponding to the Lc of Fig. 1) of the zone line of slight elastomeric element 18 is shorter than the length (corresponding to the Ld among Fig. 1) of the side of slight elastomeric element 18, and the upper end of slight elastomeric element 18 and the rear end of waist retaining part 17 are sewed up each other and formed the V font part of the aforesaid V of having glyph edges.Therefore when wearing pants 10, compare with the fabric of the side that is arranged in slight elastomeric element 18, the pointed edge from V font part that is arranged in the zone line of slight elastomeric element 18 is divided the more of the 13 fabrics extensions of extending to crotch part.Just, to promote the active force of fabric of the side that is arranged in slight elastomeric element 18 bigger for the progradation force rate that promotes the fabric of the zone line be arranged in slight elastomeric element 18.When on when drawing slight elastomeric element 18, because the length of the side that is shorter in length than slight elastomeric element 18 of the zone line of slight elastomeric element 18, therefore draw by using the active force also bigger will be arranged on the fabric of zone line than the active force that draws on the fabric that will be arranged in its left end and right-hand member.Therefore middle body can not relax, and therefore produces the active force that draws on the sanitary napkin 25.About the relation between these length, with pants 10 through puppet on before and measurement size and elastic proportional afterwards.Size and elastic proportional have been shown in the table 1.As shown in table 1, shorter before the length at the zone line place of slight elastomeric element 18 is wearing pants 10, elastic proportional is big in dress.

Table 1

The length and the elastic proportional that are used for the fabric of slight elastomeric element and fixed part

	Slight elastomeric element		Fixed part
	Slight elastomeric element		Fixed part		Middle body (zone line) (Lc)	Sidepiece (left and right end portions) (Ld)	Middle body (Lc)	Sidepiece (Ld)
	Length (cm) before wearing	13.0	14.5	7.5	Middle body (zone line) (Lc)	Sidepiece (left and right end portions) (Ld)	Middle body (Lc)	Sidepiece (Ld)	12.0

Length when wearing (cm)	Elastic proportional (%)	23.1	17.2	38.7	16.0	17.0	10.4	15.0	25.0

1) middle body (Lc): divide the length of extending to crotch part from the pointed edge of V font part.

2) sidepiece (Ld): the length of dividing the side line that extends from the sidepiece of V font part to crotch part.

Slight elastomeric element 18 can be formed by braided fabric, the for example combination of nylon fiber and/or polyester fiber, the combination of nylon fiber and polyurethane fiber, the combination of polyester fiber and polyurethane fiber, the perhaps combination of nylon fiber, polyester fiber and polyurethane fiber.The fabric that forms slight elastomeric element 18 is vertically not have for example polyurethane fiber of flexible material, thereby it has the slight elasticity of being brought by braiding structure, but the elasticity that does not have material self to produce, just the longitudinal elastic coefficient of this fabric is greater than the longitudinal elastic coefficient of high flexibility parts 19.Therefore, slight elastomeric element 18 is compared with high flexibility parts 19 and is difficult to extend.In this structure, form by the resilient material of vertical and horizontal owing to covering health buttocks and belly high flexibility parts 19 on every side, so it follows the distortion of moving the health that is caused by the wearer.But be substantially disposed in the influence of moving that slight elastomeric element 18 in the middle section at rear portion 12 is difficult to be subjected to high flexibility parts 19, because its longitudinal elastic coefficient is greater than the coefficient of elasticity of high flexibility parts 19.

The elasticity of slight elastomeric element 18 makes coefficient of elasticity preferably at 10N-60N, more preferably at 20N-50N.When coefficient of elasticity less than 10N the time, the active force that is used to promote sanitary napkin 25 can be not enough, and when coefficient of elasticity greater than 60N the time, sanitary napkin 25 can be too much enters into health slit (Figure 11).Even under the situation that slight elastomeric element 18 does not extend, although the active force that is used for drawing pants 10 directly as on draw the active force of sanitary napkin 25, but the active force that is used for drawing sanitary napkin 25 is greater than the required active force of sanitary napkin 25 is installed, this can cause sanitary napkin 25 excessively to enter into health, cause uncomfortable feeling or pain, this is that people are undesirable.On the contrary, when elasticity was excessive, when drawing pants 10 on the wearer, slight elastomeric element 18 excessively extended, so can not be effective as the active force that draws sanitary napkin 25.

On the other hand, the coefficient of elasticity of high flexibility parts 19 is less than 10N, and is preferred, in the scope at 2N-3N when extending 10-30%.In particular, wearing under the state when pants and to extend approximately 20% the time, the tension load that is applied is at 0.4-0.6N, thereby realized comfortable next to the shin lenitively along health.The coefficient of elasticity of wearing under the state means the coefficient of elasticity that obtains when pants are through on the middle-sized puppet.

Slight elastomeric element 18 can be that its percentage elongation is all identical on whole zone, as shown in Figure 5, perhaps can be that its percentage elongation little by little or discontinuously changes and reduces towards zone line from left end and rear end.Fig. 5 has shown slight elastomeric element 18 in the mode of amplifying, and its mild or moderate elastomeric element 18 is shown as its percentage elongation in the mode of illustrating and gradually changes towards zone line 18b from left end and right-hand member 18a.

As just a kind of reference, compare with pants of the prior art among Figure 12, shown the percentage elongation of slight elastomeric element 18 of pants 10 of the present invention and the relation between the hot strength.In Figure 12, the vertical pivot representation unit is the tension load of newton (N), and the transverse axis representation unit is the percentage elongation of %.Curve A is corresponding to pants of the present invention, and curve B is corresponding to the pants of prior art.

As shown in figure 12, when the slight elastomeric element in the basic middle section that is arranged on the pants rear portion in the prior art extended 30%, the tension load that is applied was P1.On the other hand, when the slight elastomeric element 18 of pants 10 of the present invention extended 30%, the tension load that is applied was P2, and the hot strength that this means pants 10 of the present invention is greater than pants of the prior art.In other words, pants 10 of the present invention tension load than pants of the prior art under same percentage elongation is big.Even wearing when only extending 10% under the state when pants 10 of the present invention, the hot strength that imposes on pants 10 of the present invention also is the P3 bigger than the hot strength of pants of the prior art.In other words, even when percentage elongation less than the pants of prior art the time, the hot strength that imposes on pants 10 of the present invention is still bigger, and the slight elastomeric element 18 that this means pants 10 of the present invention becomes effectively and spurs crotch part and divide 13 active force.Therefore draw the active force of overnight hygienic band 25 on having increased, thereby sanitary napkin 25 better is suitable for the crotch part branch of health.

The fixed part 20 of pants 10 is formed by strong net (power net), and is arranged on anterior 11 basic middle section.Its upper end is sewn to around the V font pointed edge partly of waist retaining part 17 with waist retaining part 17, and its lateral edges is sewn on the high flexibility parts 19.Forwardly the crotch part on 11 1 sides divides 13 end (crotch part divides 13 front end), its lower end and sanitary napkin lift portion 21 and constitute crotch part and divide 13 sanitary napkin that cloth 16 is installed to be stitched together, perhaps to be stitched together with high flexibility parts 19.Fixed part 20 divides 13 to be tapered from waist retaining part 17 towards crotch part, and be arranged on crotch part and divide the sanitary napkin lift portion 21 of 13 basic centre to be stitched together.The width of the front end of the sanitary napkin lift portion 21 in the width of the part that standing part 20 and sanitary napkin lift portion 21 are sewed up, basic and a side that is arranged on front portion 11 is identical.The upper end of sewing up with waist retaining part 17 forms basic V font, and its width is at 60mm-150mm, preferably at 80-120mm.

The length of the middle body of fixed part 20 (corresponding to the Lc among Fig. 1) is shorter than the length (corresponding to the Ld among Fig. 1) of its left side and right-hand end, and the rear end of the upper end of fixed part 20 and waist retaining part 17 is sewed up, to form V font part as mentioned above.Therefore, as the situation in slight elastomeric element 18, when fixed part 20 by on when drawing, the middle body of fixed part 20 is by drawing (seeing Table 1) on the bigger active force of the active force that is used for promoting its left side and right-hand end.Therefore middle body can not relax, and has produced the active force that is used for drawing sanitary napkin 25.

The strong net that constitutes fixed part 20 is that the RIPSTOP and the polyurethane fiber that are higher than 100dtex form, longitudinal elastic coefficient is greater than the longitudinal elastic coefficient of high flexibility parts 19, just, constitute the poor flexibility of the strong meshi fabric of fixed part 20 than high flexibility parts 19.The longitudinal tensile strength of fixed part 20 makes its coefficient of elasticity at 10N-30N, more preferably at 15N-30N.The type or the mixed proportion of the fiber in the strong net of formation fixed part 20 are not limited thereto, and can suitably select to obtain above-mentioned effect.

As shown in Figure 6, sanitary napkin lift portion 21 is arranged on crotch part and divides 13 centre substantially, and forms the part that crotch part divides, and described crotch part divides 13 to be to form by the crotch's fabric 24 with high flexibility parts 19 materials similar.One end of sanitary napkin lift portion 21 is sewed up with the lower end of the slight elastomeric element 18 at the basic middle section place that is arranged on rear portion 12, and the other end of sanitary napkin lift portion 21 is sewed up with the lower end of the fixed part 20 at the basic middle section place that is arranged on front portion 11.The both side ends of fixed part 20 and formation crotch part divide crotch's fabric 24 stitchings of 13.Sanitary napkin lift portion 21 from extend towards circumanal part around the contacted part of pubis, and the front end on a side of anterior 11 is tapered towards the rear end on 12 1 sides of rear portion.The width of sanitary napkin lift portion 21 is 50mm-80mm in wide portions, and more preferably about 70mm is 10-30mm in narrower part, more preferably about 20mm.

Sanitary napkin lift portion 21 is similar with slight elastomeric element 18, form by braided fabric, the for example combination of the combination of the combination of the combination of nylon fiber and/or polyester fiber, nylon fiber and polyurethane fiber, polyester fiber and polyurethane fiber or nylon fiber, polyester fiber and polyurethane fiber, vertically comprising there is not for example polyurethane fiber of flexible material, have the slight elasticity of being brought by the braiding structure variation, but the elasticity that does not have material self to produce.It is formed by the fabric of longitudinal elastic coefficient less than the longitudinal elastic coefficient of slight elastomeric element 18, and the fabric that just constitutes sanitary napkin lift portion 21 has more elasticity than slight elastomeric element 18.

The elasticity of sanitary napkin lift portion 21 preferably makes its coefficient of elasticity at 5N-30N, more preferably at 10N-25N.When coefficient of elasticity less than 5N the time, the active force that is used to promote sanitary napkin 25 middle bodies is just not enough.When coefficient of elasticity greater than 30N the time, its elasticity has surpassed the elasticity of slight elastomeric element 18, is difficult to therefore make that the middle body of sanitary napkin 25 is fit to the suspention effect in health gap.

Sanitary napkin lift portion 21 can form in the following manner, its width is tapered towards zone line from the part (the wideest part) with fixed part 20 stitchings, increase once more towards part as shown in Figure 7, and from middle zone with slight elastomeric element 18 stitchings.In this case, sanitary napkin lift portion 21 is at the width of the part of sewing up with slight elastomeric element 18 width less than the part of sewing up with fixed part 20.

As shown in Figure 8, sanitary napkin dress is arranged on crotch part with fabric 16 and divides on 13 the inboard.Sanitary napkin dress forwardly is sewn to crotch part on 11 the side with the front end of fabric 16 and divides on 13, and sanitary napkin is adorned rear end with fabric 16 and is sewn to crotch part divides on 13 on 12 1 sides of rear portion.The sanitary napkin dress is by polyester circle spot (circular dappled) braiding waterproof fabric that forms and the braided polyester fabric that is used to protect the stacked film surface that polyurethane is stacked, the fabric-film integral body that is stitched together and forms around left end and right-hand member with fabric 16.Sanitary napkin dress is to divide 13 length L 1 identical or bigger with crotch part as shown in Figure 9 with the length L 2 of fabric 16.In particular, crotch part divides 13 length at 140-190mm, preferably at about 160mm.The sanitary napkin dress uses the length L 2 of fabric 16 in the scope of 140-220mm, preferably at about 200mm.

The high flexibility parts 19 of pants 10 are formed by the semi-dull fabric of black.Waist retaining part 17, slight elastomeric element 18 and sanitary napkin lift portion 21 are formed by dark brown fabric.The strong net that constitutes fixed part 20 can be different with the fabric color of high flexibility parts 19.In this manner, no matter preferably make waist retaining part 17, slight elastomeric element 18, sanitary napkin lift portion 21 and fixed part 20 is different with high flexibility parts 19 colors or whether color is identical, make their reflective difference by the amount of the titanium oxide that change to mix, thereby these parts that are used to promote sanitary napkin can be distinguished with the naked eye.

With reference to Figure 10 and Figure 11, the behavior of slight elastomeric element 18, sanitary napkin lift portion 21 and fixed part 20 when wearing pants 10 of the present invention is described.Figure 10 is the schematic section of the pants around the health crotch, has shown slight elastomeric element, sanitary napkin lift portion and fixed part are how to move around health crotch when wearing pants of the present invention.Reference marker BD represents health, and reference marker LG represents leg.Figure 11 is the schematic transverse sectional view of the pants part around the introitus, has shown in the behavior of wearing near the part of the pants introitus under the state.Reference marker I among Figure 11 is an introitus, and the reference marker IT between leg LG represents the inboard of femur.

When wearing pants 10, as shown in figure 10, by receiving the lifting force T1 that slight elastomeric element 18 is brought, be used for locating sanitary napkin lift portion 21 is displayed with the active force T3 that covers the health gap towards the rear portion pulling at some A (fixed part and crotch part minute 13 parts of sewing up each other, it contacts with the pubis of health) as the strong point.Be used for drawing the active force T3 of sanitary napkin lift portion 21 to draw the active force of the middle body of sanitary napkin 25 on becoming then.The width of sanitary napkin lift portion 21 around the A is about 70mm, and is tapered to the width of about 20mm towards introitus, perineum and anus (towards a B, it is to divide sutured portion between 13 at slight elastomeric element 18 and crotch part).By this way, because the width of sanitary napkin lift portion 21 on an A is wide, it is fixing can prevent that sanitary napkin lift portion 21 from moving to the right or to the left therefore to put A, and the central authorities of sanitary napkin lift portion 21 can be around introitus.Therefore if the width of the sanitary napkin lift portion on an A is narrow to 20mm, sanitary napkin lift portion 21 may move to right side or left side, may not can be positioned at around the introitus wearing under the state its center, and this is not preferred.

As shown in figure 11, because near the width of sanitary napkin lift portion 21 introitus is narrow to 20mm, the fabric that the coefficient of elasticity of sanitary napkin lift portion 21 is projecting, therefore it extends under the effect of stronger active force, and produces and be used for the active force T4 that the middle body with sanitary napkin 25 upwards promotes.

As shown in figure 10, sanitary napkin lift portion 21 by the active force T1 that is brought by the slight elastomeric element 18 of layback on rear portion 12 backward (rear portion 12) draw.Therefore, produce the active force that sanitary napkin lift portion 21 is moved backward at an A place.When sanitary napkin lift portion 21 moved backward along with an A, the active force that makes sanitary napkin 25 be fit to health that sanitary napkin lift portion 21 is applied just was difficult to be affected.In other words, when whole sanitary napkin lift portion 21 moves backward, do not produce the active force that makes sanitary napkin 25 be fit to health.For fear of this state, preferably firmly fix an A as far as possible.On the other hand, anterior 11 fixed part 20 applies active force and fixes an A.In other words, be seamed to the outside of the high flexibility parts 19 of pants 10, may weaken the active force T2 that in the front portion 11 that vertical direction extends, produces tending to by the strong net that will constitute fixed part 20.By this way,, reduce by anterior 11 extension by fixed part 20 is sewed up thereon, so fixing point A, and can not spurred by slight elastomeric element 18 and sanitary napkin lift portion 21.The longitudinal elastic coefficient of the fabric of the strong net of formation fixed part 20 is preferably at 10N-30N, because if it is formed by non-elastic fabric, forwardly the waist opening of 11 upper end part may glide, this be because with anterior 11 contacted bellies are the parts that move obvious distortion according to wearer's body, therefore exist the danger of infringement fitness.

Put A herein corresponding to the stitch points between fixed part 20 and crotch part minutes 13, just round with around the contacted part of the pubis of health, point B is corresponding to the sutured portion between slight elastomeric element 18 and crotch part minutes 13, just with respect to the part of anus on 12 1 sides of rear portion, and from pubis (on a side at rear portion 12) about part of 150mm-200mm backward.

The flexible method that is used to measure pants parts (slight elastomeric element, sanitary napkin lift portion, fixed part and high flexibility parts) is below described.

The measurement of＜slight elastomeric element 〉

Dividing 13 rear end with crotch part is that the position at 100mm clamping distance place is with clamp (size of clamping surface is the rectangle of 30mm * 25mm) towards waist opening part 14 directions with slight elastomeric element 18 suture location that (crotch part divides 13 rear end) unites by a seam on 12 1 sides of rear portion and apart from this suture location, use stretching testing machine with the draw speed extension 50% of slight elastomeric element 18 with 100mm/min, the one-off drawing load is measured in every stretching 10%.

The measurement of＜sanitary napkin lift portion 〉

With sanitary napkin lift portion 21 and anterior 11 sutured portion of sewing up and apart from this suture location towards the rear portion 12 of pants 10 for the position at 150mm clamping distance place with clamp (size of clamping surface is the rectangle of 35mm * 25mm), use stretching testing machine with the draw speed extension 50% of sanitary napkin lift portion with 100mm/min, the one-off drawing load is measured in every stretching 10%.

The measurement of＜fixed part 〉

With fixed part 20 and crotch part divide 13 sutured portion that forwardly (crotch part divides 13 front end) sewed up on 11 1 sides and apart from this suture location towards the waist opening part 14 of pants 10 for the position at 80mm clamping distance place with clamp (size of clamping surface is the rectangle of 35mm * 25mm), use stretching testing machine with the draw speed extension 50% of fixed part 20 with 100mm/min, the one-off drawing load is measured in every stretching 10%.

The measurement of＜high flexibility parts 〉

The high flexibility parts 19 of pants 10 are cut into the loose size of 130mm length * 25mm.The bar that cuts by clamp (size of clamping surface is the rectangle of 35mm * 25mm) uses stretching testing machine with the draw speed extension 50% of high flexibility parts 19 with 100mm/min then, and the one-off drawing load is measured in every stretching 10%.

Coefficient of elasticity is the value that obtains divided by the extension ratio of correspondence by the tension load that will obtain in said method.For example, be under the situation of 10N in extension 20% and tension load, coefficient of elasticity is 10N/0.2=50N.

With reference to Figure 13 and Figure 14, the pants 10a of second embodiment of the invention and the pants 10b of the 3rd embodiment are described.Figure 13 is the rearview that shows the pants 10a of second embodiment, shown inboard outwardly and be folded into two so that the state that front and rear contacts with each other.Figure 14 is the rearview of the another kind of form of second embodiment shown in Figure 13.In this embodiment, the parts identical with first embodiment are represented by identical Reference numeral, omit its repeat specification.

The pants 10a of second embodiment shown in Figure 13 is the pants different with the pants 10 in first embodiment, wherein width is 30-140mm, the waterproof fabric 26 that is more preferably the 80mm order of magnitude is arranged on the inboard of pants 10a in the basic middle section at rear portion 12, and it divides 13 to extend to waist retaining part 17 from crotch part.Waterproof fabric 26 is sewn to that crotch part divides 13, on waist retaining part 17 and the slight elastomeric element 18, thereby become one with the main body of pants 10a.The left end of waterproof fabric 26 and right-hand member are not sewed up with the rear portion 12 of pants 10a, thereby can not suppress the tensile property of pants 10a.

As in the situation of above-mentioned sanitary napkin installation cloth 16, waterproof fabric 26 is by polyester circle spot (circular dappled) braiding waterproof fabric that forms and the braided polyester fabric that is used to protect the stacked film surface that polyurethane is stacked, sews up the fabric-film integral body that forms on every side at left end and right-hand member together.The elasticity of the vertical and horizontal of waterproof fabric 26 can not damaged the elasticity of pants 10a main body.

By in the basic middle section at rear portion 12 waterproof fabric 26 being set on the pants 10a inboard, when discharged when blood volume has surpassed the absorbability of sanitary napkin, the menses that flow on the sanitary napkin are absorbed by waterproof fabric 26, prevent to drain to pants 10a outside.

Waterproof fabric 26 can be provided with as follows, and wherein the lower end of waterproof fabric 26 does not extend to crotch part always and divides 13, but extends to the basic stage casing at rear portion 12 from waist retaining part 17.In other words, waterproof fabric 26 can extend to not by the part that sanitary napkin covered from waist retaining part 17, thereby is arranged on the waterproof fabric 26 at the front end of wearing sanitary napkin under the state.Waterproof fabric 26 is sewn on waist retaining part 17 and the slight elastomeric element 18, and its lower end is on the high flexibility parts 19b at rear portion 12 rear side, thereby becomes one with the main body of pants 10b.The left end of waterproof fabric 16 and right-hand member do not have to be stitched together with the main body of pants 10b, thereby can not damage the elastic characteristic of the main body of pants 10b.
