JP4912200B2 - Pants-type disposable diaper and method for manufacturing the same - Google Patents

Description

  The present invention relates to a pants-type disposable diaper and a continuous manufacturing method thereof.

Conventionally, a pants-type disposable diaper having a front body and a back body that are continuous via the crotch part, both sides of the front body and the back body are joined, and a leg opening and a waist opening are formed. Is well known.
The pants-type disposable diaper is worn through the legs from the waist opening toward the leg opening. There is a merit that it is easy to put on and take off by the wearer by adopting the same wearing method as general clothing.
By the way, in the case of general men's underwear, a slit for taking out the penis is provided in the front body, and if it is a man, this slit and opening and closing provided in clothing such as pants can be opened and closed The urination is performed by exposing the penis to the outside through a special zipper.
JP-A-2005-124594 JP-A-2005-137460

However, the conventional diaper is not provided with a means for putting out the penis to the outside while wearing the clothes, as provided in the clothes.
For this reason, many diaper wearers who can urinate on their own, when exposing the penis when urinating, lower the clothes and diaper to the bottom of the penis, squeeze the waist opening edge of the diaper by hand, A complicated operation such as taking out the penis from the opening around the leg is performed.
In Patent Documents 1 and 2, a diaper having a hole communicating with the inside and outside of the front body is disclosed. However, when a garment is worn over the diaper, a penis exposure operation cannot be performed.
On the other hand, the pants-type disposable diaper has only a brief shape having an opening edge around the leg in a V shape from the bottom of the crotch to the waist on both sides. If the penis is exposed from the opening around the leg, the brief shape is excellent.
However, underwear that is not a diaper has various shapes such as a trunks type and a boxer type, and some people prefer designs such as the trunks type over the brief type.
It would be preferable if the room for selection of designs other than the brief shape could be increased along with improvement of the complexity of the penis exposure.
Therefore, the main problem of the present invention is to provide a pants-type disposable diaper that can easily expose the penis to the outside and easily urinate, and a continuous manufacturing method thereof, and has an unprecedented design and fit. It is in providing the underpants type disposable diaper which is excellent in, and its manufacturing method.

The present invention and effects obtained by solving the above problems are as follows.
<Invention of Claim 1>
A pants-type disposable diaper in which a front body and a back body are joined on both sides to form a waist opening and a pair of leg openings,
At least the front body includes an exterior sheet having a hollowed hole communicating with the inside and outside in the widthwise central portion of its, the sheet-like covering member covering the cut-out holes,
The sheet-like covering member has an opening for passing a male genus extending between the waist opening edge and the crotch at a position in the cutout hole , and extends from the front body to the back body. Having an absorber,
A pants-type disposable diaper characterized by that.

(Function and effect)
The disposable diaper of the present invention has an opening for passing male genitalia, extending between the waist opening edge and the crotch, at the center in the width direction of the front body. Therefore, it is possible to expose the penis while wearing the diaper.
Moreover, the disposable diaper of this invention has an absorber extended from the front body to the back body. Therefore, it also has the original absorption function of diapers.

Moreover, in this invention, since the opening part was formed in the sheet-like coating | coated member, an exterior sheet and a covering-like raw material can be made different. For example, the sheet-like covering member facing the penis can be formed of a soft material, and the exterior sheet can be designed of a strong material.
Further, the cut-out hole formed in the exterior sheet is fragile as compared with other portions, and is easily deformed by an external force. By joining a soft sheet-like covering member to the cutout hole , the cutout hole can be easily deformed when the diaper is attached or detached, and the risk of avoiding the opening can be reduced.

<Invention of Claim 2 >
The sheet-like covering member has two sheets, the opening is its two edges superimposed edges formed by overlapping of the sheet, pull-on disposable diaper according to claim 1, wherein .

(Function and effect)
Even if the opening opens unintentionally, the penis will not be exposed accidentally.

<Invention of Claim 3 >
Along the opening resilient and elastic members are arranged, according to claim 1 or 2 pants type disposable diaper according.

(Function and effect)
The opening becomes easier to open and the penis is more easily exposed.

<Invention of Claim 4 >
Each front and back body is recessed at the substantially center position of the opposite side edge to the waist opening edge, and the distance from the bottom position of the recess to the waist opening edge is shorter than the length of the side edge,
In the disposable diaper, both side edges of the front and rear bodies and the recessed notch edges are connected to each other, and a leg opening is provided at the tip at the lower part of the both side edge joined parts and the recessed notch edge joined part. The pants-type disposable diaper according to any one of claims 1 to 3 , wherein a crotch cylinder part is formed.

(Function and effect)
Since the diaper of the present invention has an opening for exposing the penis, it is not inferior in terms of penis exposure as compared with a brief shape that can expose the penis from the opening around the leg.
And it can be made to fit around a thigh by having formed a leg cylinder part. Further, since the leg opening is separated from the crotch position, the leakage preventing effect is excellent.
For example, if an elastic elastic member along the tube periphery direction is arranged on the leg periphery tube portion, the leg periphery tube portion can be effectively fitted around the thigh.
Moreover, since the crotch position is recessed, it is easy to fit in the crotch part, and it is excellent in a feeling of mounting and a leak prevention effect.
Furthermore, it has a notch at the crotch position and a leg cylinder, so it has a design that is very close to trunks-type underwear, and it is particularly difficult to form extra pockets on both sides under the crotch. It is excellent in the feeling of wearing and the appearance at the time of wearing.

"Pants-type disposable diapers"
[First form (reference form) ]
The underpants type disposable diaper X1 which concerns on a 1st form is demonstrated referring the front view of FIG. 1, and the expanded view of FIG.
The pants-type disposable diaper X1 is mainly composed of an exterior body 1 and an absorbent body 3 fixed to the inner surface of the exterior body 1.
The exterior body 1 is formed with leg peripheral edges EL and EL that are recessed at the center in the front and rear direction on both sides and curved in the center in the width direction. A liquid-impervious and breathable exterior sheet 11 having a substantially hourglass-shaped planar outer shape formed with a ventral waist part Fs and a back waist part Bs wider than between the peripheral edges EL and EL. Side portions of the abdomen waistline portion Fs and the back waistline portion Bs of the seat 11 are joined to form a pants shape having a waist opening WO and a leg periphery opening LO.
Further, the exterior body 1 includes a plurality of waist elastic elastic members 24, 24,... Arranged along the waist opening edge We and a plurality of waist elastic portions Fs and back waist parts Bs arranged along the waist direction. Are arranged around the leg-circumference edge EL, and are provided with leg-elastic elastic members 26, 26,. In addition, the arrangement | positioning form of an elastic expansion-contraction member is not restricted to this, It can select suitably and employ | adopt from the techniques employ | adopted as a conventionally well-known underpants type disposable diaper.
As the material of the exterior sheet 11 constituting the exterior body 1, a material in which an appropriate elastic elastic member is disposed between two layers of nonwoven fabric sheets 11s and 11s is typically used. However, it is not limited to this, It can select suitably from the sheet | seat materials used as a known diaper exterior.

Here, the crotch in the pants-type disposable diaper means that around the left leg in the unfolded state when the exterior sheet having the leg periphery EL recessed in the left and right in the unfolded state is adopted. It is a position on the line connecting the middle position of the line connecting both ends of the edge and the middle position of the line connecting the both ends of the right leg around the edge. The body is B.
On the other hand, a slit hole 10 is characteristically formed in the front body F of the exterior body 1 as an opening for penis exposure that extends between the waist opening edge We and the crotch at the center in the width direction. . The slit hole 10 of this embodiment is provided by directly cutting the exterior sheet 11.
In the illustrated example, only the slit hole 10 is provided. However, in order to prevent unnecessary slitting of the slit hole 10, a hot melt adhesive is applied around the slit hole 10, particularly in the vicinity of both ends, or heat melting is performed. It is good to process. Further, in order to prevent inadvertent exposure of the penis, the flap sheet 10F may be disposed so as to cover the slit hole as shown in FIG.
The length L1 of the slit hole 10 is 5 to 30 cm, preferably 10 to 20 cm from the viewpoint of penis exposure. If it is less than 5 cm, it is difficult to expose the penis, and if it exceeds 30 cm, the risk of inadvertently exposing the penis increases.
The position of the slit hole 10 should be formed within 10 cm, preferably within 5 cm, from side to side from the center of the diaper in the width direction. If it exceeds 10 cm, it will be difficult to expose the penis.
The position of the waist opening edge side end 10w of the slit hole 10 is preferably 5 cm or more, preferably 10 cm or more away from the waist opening edge We. If it is less than 5 cm, the risk of deterioration between the fits of the waist increases.

The position of the crotch side end 10c is preferably set to a position separated from the crotch C position of the exterior body 1 by 0 cm or more, preferably 3 cm or more, and on the waist opening edge We side. If it is less than 3 cm, the front body side portion of the absorbent body 3 is inevitably reduced, and the urine absorption function as a diaper is hardly exhibited effectively.
On the other hand, in this embodiment, the absorber 3 is disposed so as to extend from a position closest to the crotch side end 10c of the slit hole 10 to an appropriate position of the back body B. However, it is not limited to this. It may be in the back body only.
If configured as in the illustrated example, the distance between the crotch side end 10c of the slit hole 10 and the front body side edge 3f of the absorbent body 3 is 5 cm or less, preferably 2 cm or less. If it exceeds 5 cm, urine collects between the slit hole and the absorber when the urination action is not performed by itself, that is, when the absorption function of the diaper is used, and the risk of leakage of urine from the slit portion increases.

The structure of the absorber 3 can be a known layer structure in which an absorbent core 33 is disposed between a liquid-permeable top sheet 31 and a liquid-impermeable back sheet 32. In the present embodiment, the absorbent core 33 is formed in a circular arc shape in the front-rear direction center on both sides along the leg periphery edge EL of the exterior sheet 11, and the fit to the leg periphery is enhanced.
As the liquid-permeable top sheet 31 that covers the surface side (skin contact surface side) of the absorbent core 33, a porous or non-porous nonwoven fabric or a porous plastic sheet is preferably used. The material fibers that make up the nonwoven fabric can be synthetic fibers such as olefins such as polyethylene or polypropylene, polyesters, and polyamides, recycled fibers such as rayon and cupra, and natural fibers such as cotton. A nonwoven fabric obtained by an appropriate processing method such as a spun bond method, a thermal bond method, a melt blown method, or a needle punch method can be used. Among these processing methods, the spunlace method is excellent in terms of flexibility and drapeability, and the thermal bond method is excellent in terms of being bulky and soft. When a large number of through holes are formed in the liquid-permeable surface sheet 31, urine and the like are quickly absorbed, and the dry touch property is excellent.
As the liquid-impervious back sheet 32 covering the back side (non-skin contact surface side) of the absorbent core 33, a liquid-impervious plastic sheet such as polyethylene or polypropylene is used. Those having wettability are preferably used. This water-impervious / breathable sheet is a microporous sheet obtained by, for example, melt-kneading an inorganic filler in an olefin resin such as polyethylene or polypropylene to form a sheet, and then stretching in a uniaxial or biaxial direction. If the sheet thickness is the same, the rigidity is lower than that of the non-porous sheet, which is superior in terms of flexibility.

The absorbent core 33 is made of an absorbent polymer dispersed in fibers such as piled pulp and nonwoven fabric and encased by a liquid-permeable sheet such as crepe paper, nonwoven fabric sheet or perforated sheet.
Examples of the superabsorbent polymer include carboxymethyl cellulose, polyacrylic acid and salts thereof, acrylate polymer cross-linked product, starch-acrylic acid graft copolymer, starch-acrylonitrile graft copolymer hydrolyzate, polyoxyethylene cross-linked product Products, crosslinked products of carboxymethyl cellulose, polyethylene oxide, polyacrylamide and other partially crosslinked polymers, or a copolymer of isobutylene and maleic acid are preferably used. What added the blocking inhibitor in order to suppress the blocking property by moisture absorption of a product can also be used. In addition, the superabsorbent polymer has various forms such as powder, particles, granules, pellets, sol, suspension, gel, film, and nonwoven fabric. Any of them can be used, and in particular, particles are preferably used.

As the various elastic elastic members 24 to 26 used in the disposable diaper X1 of this embodiment, rubber thread is typically used. As the thread rubber, those made of synthetic rubber or natural rubber and those mainly composed of natural rubber are suitable. In addition to the rubber thread, a material having rubber elasticity, which is formed (molded) into a thread shape, a string shape, a belt shape, a net shape, a foam shape, or the like, including a generally well-known elastomer resin can be used. For example, materials such as styrene rubber, olefin rubber, urethane rubber, ester rubber, polyurethane, polyethylene, polystyrene, styrene butadiene, silicon, and polyester can be used.
In addition, although it is suitable for the opening part for penis exposure to be the shape of a slit hole as shown to this form, it is not limited to this. An appropriate shape can be obtained. The same applies to the following second and third embodiments. However, the length of the diaper in the width direction is preferably about 2 to 10 cm, particularly about 2 to 5 cm. If it is too wide, the risk of unintentional exposure of the penis increases.

[Second Embodiment (Embodiment of the Present Invention) ]
Next, a pants-type disposable diaper X2 of the second form will be described with reference to FIGS. 4 is a front view, FIG. 5 is a developed view, and FIG. 6 is a sectional view taken along the line IV-IV in FIG. FIG. 7 is a view showing another example of the slit hole.
This pants-type disposable diaper X2 is an example in which the slit hole 10 as an opening is not formed by directly incising the exterior sheet 11, but is formed through another member. Description of matters common to the first embodiment is omitted.
The exterior body 1 of the pants-type disposable diaper X2 includes an exterior sheet 11 in which a cutout hole 1H is formed at a predetermined position of the front body F, and a sheet-like covering member 2 having a slit hole 10.
The slit hole of the exterior body 1 is formed by joining the sheet-like covering member 2 having the slit hole 10 to the exterior sheet 11 so as to cover the cutout hole 1H of the exterior sheet 1.

Although it is not limited to which of the inner and outer surfaces of the exterior sheet 11 the sheet-shaped covering member 2 is bonded, it is preferably bonded to the inner surface side as illustrated. The sheet-shaped covering member 1 can be joined to the exterior sheet 11 by a known bonding method such as heat fusion, thermocompression bonding, ultrasonic welding, or hot melt bonding at the peripheral edge of the hole 1H.
Here, the cut-out hole 1H in the exterior sheet 11 is based on the position where the male genital faces when worn, and has a size that allows the penis to pass through.
The specific size and the like of the cut-out hole 1H can be appropriately designed in a range corresponding to the length and position of the slit hole. Preferably, the cut-out hole has a width direction length L2 of 5. The length L3 in the front-rear direction is preferably about 10 to 20 cm. Further, it is preferable that the waist opening edge We is separated from the crotch by about 10 cm and from the crotch by about 5 cm.
The shape of the cut-out hole 1H is not particularly limited, but it may be a target shape at the center line of the diaper. In the illustrated example, a bowl shape is used, but a round shape, an oval shape, or the like can be used.

On the other hand, in the present embodiment, the sheet-shaped covering member 2 in which the slit hole 10 is formed has one longitudinal edge portion of two rectangular sheets 2A and 2B overlapped, and both longitudinal end portions of the overlapping longitudinal edge portion. It is formed into a single sheet by adhering with, and the edge of the overlapping portion becomes the slit hole 10.
The shape of the sheet-like covering member 2 is not necessarily limited as long as it has the slit hole 10 according to the present invention. Moreover, if it is a magnitude | size which can coat | cover the cut-out hole 1H completely, it will not be limited in the range which can be joined to the front body F of the exterior sheet 11.
By forming the overlapped portion, the slit hole 10 is prevented from being unintentionally opened unintentionally during normal use (when not in use). The overlap length L4 is preferably about 1 to 5 cm. If it exceeds 5 cm, it will be difficult to remove the penis. If it is less than 1 cm, the merit of forming the overlapped portion is hardly exhibited. The length of the slit hole 10 is the same as in the first embodiment.

On the other hand, as shown in FIG. 7, the sheet-shaped covering member 2 can be provided with elastic elastic members 27 along the slit hole 10 at the edge of the slit hole 10. Moreover, although not shown in figure, the sheet-like covering member 2 can adopt a slit formed by cutting a part of one sheet.
The sheet-like covering member 2 can be formed of the same material as the non-woven sheet used for the exterior sheet 11, for example, a film sheet having a high leak-proof property unlike the exterior sheet, or penis contact Different materials can be employed to give the exterior sheet 11 different functions, such as a material that is softer than the exterior sheet in view of the position.

[Third Embodiment (Embodiment of the Present Invention) ]
Next, a pants-type disposable diaper X3 according to a third embodiment will be described with reference to FIGS. This underpants type disposable diaper X3 is an example in which the exterior body 1 has a trunks shape. Description of parts common to the first and second embodiments is omitted.
The exterior body 1 of the pants-type disposable diaper X3 is composed of a front body sheet 11F constituting the front body and a back body side sheet 11B constituting the back body. That is, the exterior sheet is a separate body for the front body and the back body.
The front body sheet 11 and the back body sheet 12 are each in a plan view; the front body sheet 11 and the rear body sheet 12 have a recessed portion Z that is recessed at a substantially crotch position on the opposite side edge to the waist opening edge We. 12, the length L5 of the side part serving as the side joining edge is longer than the length of the distance L6 from the bottom position of the recess to the waist opening edge We, and extends from the crotch position to the leg tip side. Has a shape.

The exterior body 1 is composed of a waist opening edge We, a lower portion of the side joint Ec, and a concave notch edge joint Zc in which the side parts of the front and rear body sheets 11 and 12 and the notch edge part are joined. A characteristic crotch tube portion LP and a leg opening LO are formed on the leg tip side.
As the specific shape of the concave portion Z, an appropriate shape such as an arch shape, a triangular shape, a trapezoidal shape, a square shape, or the like can be adopted, and an arch shape, particularly a parabolic shape like the illustrated example is suitable.
The crotch tube portion LP has a crotch length L7 of about 2 to 20 cm and a tube size of 15 to 60 cm from the viewpoint of design, fit around the thigh, and leakage prevention. It is better to design appropriately according to the usage.

In the exterior body 1 of the present embodiment, the leg elastic cylinder member LP is formed as the elastic elastic member, and therefore, a plurality of elastic elastic members 28 around the thighs in the crotch cylinder part LP along the cylinder circumference direction. 28 ... are arranged. The arrangement | positioning aspect of the elastic expansion-contraction members 28,28 ... in parts other than the leg periphery cylinder part LP can be suitably selected from the techniques employ | adopted as a conventionally well-known underpants type disposable diaper, and can be employ | adopted. As for the elastic elastic member, as another example of the present embodiment, a concave notch is formed along with the elastic elastic members 26, 26 around the thigh or in place of the elastic elastic members 26, 26, or along the legs, the groin, the groin, etc. A curved elastic elastic member that curves from the side edge toward the waist opening edge side position of the side portions on both sides can be exemplified.
The thigh elastic elastic members 28, 28... Provided in the inseam cylinder portion LP have a thickness of 1000 dtex or less, a tension of 150 to 400%, and an interval of 20 mm or less in consideration of the fit around the thigh. It is good to arrange.

In the disposable diaper of this embodiment, in the exterior body 1, the slit hole 10 for exposing the penis as shown in the first and second is formed.
In the illustrated form, the slit hole 10 is formed by joining the sheet-like covering member 2 having the slit hole 10 to the front body sheet 11 having the hollow 1H as in the second embodiment. It is not limited to.
In addition, in the case of the trunks type which does not have a notched leg periphery edge like the exterior body 1 of this embodiment, the defined crotch is the most waist opening edge We of the notched edge joint portion Zc. It is a range that extends in the diaper width direction with a near position as the center, and that extends at least as long as the distance between the opening side ends of the concave notch edge joint portion.

"Production method for pants-type disposable diapers"
[Method for producing first-type pants-type disposable diaper]
Next, an example of a method for manufacturing the disposable diaper X1 according to the first embodiment will be described with reference to FIG.
In the diaper manufacturing method of this embodiment, first, as shown in FIG. 10 (A), the continuous exterior sheet S that becomes the exterior body 1 is continuously supplied in the line direction.
The continuous exterior sheet S is a sheet in which a continuous elastic stretchable member (not shown) is interposed at an appropriate position between the continuous upper nonwoven fabric sheet and the continuous lower nonwoven fabric sheet.
The method of interposing an elastic elastic member between continuous nonwoven fabric sheets is a known method. For example, a method of laminating the other nonwoven fabric sheet on the nonwoven fabric sheet while fixing the elastic elastic member with one of the nonwoven fabric sheets with a hot melt adhesive or the like, It is possible to adopt a method in which an elastic stretchable member is sandwiched between the two.

Next, as shown in FIG. 10B, in the process of supplying the continuous exterior sheet S, the slit hole 10 extending in the sheet width direction is intermittently formed on one side with the width center of the continuous exterior sheet S as a boundary. To form. The slit hole 10 can be formed by an appropriate cutter device such as a roll cutter. After the slit hole 10 is formed, a process for improving the strength may be performed by appropriately melting both ends of the slit hole. Further, a linear fused portion or the like may be formed, and a slit hole may be formed in the fused portion or the like.
On the other hand, before or after or simultaneously with the formation of the slit hole 10, the absorber 3 is intermittently supplied onto the sheet by offsetting the width of the continuous exterior sheet S to the other side across the boundary. And fix. The supply of the absorbent body 3 onto the continuous exterior sheet S may be performed using a known conveyor device. Fixing may be performed by a hot melt adhesive, and can be performed by a known technique in which the hot melt adhesive is applied to the position of the sheet S or the back surface of the absorber 3.

On the other hand, the leg peripheral hole LH is intermittently formed in the center of the width of the continuous exterior sheet S before or after the slit hole 10 is formed and the absorber 3 is fixed. A known technique using a roll cutter or the like can be used for forming the leg peripheral hole.
After the slit hole 10 and the leg peripheral hole LH are formed and the absorber 3 is fixed, as shown in FIG. 10C, the width Sc (center in the illustrated example) of the continuous exterior sheet S is defined as a boundary Sc. One side of the continuous exterior sheet S together with the absorbent body 3 is folded back to the other side to be folded in two. For folding the continuous sheet S, a sheet folding technique of a pants-type disposable diaper can be employed. At this time, one side or the other side is the front body and the back body, respectively.

  The folded continuous sheet S ′ is a sheet that faces in a subsequent step so that linear joints E ′ and E ′ are formed at positions between adjacent absorbers as shown in FIG. 10D. The parts are joined continuously. Of course, the leg hole edge is not joined. These linear joint portions E ′ and E ′ are portions that become both-side joint portions Ec and Ec of the front and rear bodies, and a known side portion joint formation technique for a pants-type disposable diaper can be employed. As specific joining means, for example, means of heat fusion, thermocompression bonding, and ultrasonic welding can be employed. Further, the specific configuration of the joint portion, for example, the width of the joint portion, solid joint or pitch joint is an appropriate design matter, and a known technique can be appropriately employed.

After joining side part E ', as shown to FIG.10 (E), it cut | disconnects for every absorber presence part in the state which maintained the joining of the position between adjacent absorbers.
Thus, the pants-type disposable diaper X1 according to the first embodiment having the penis exposing slit hole 1H shown in FIGS.
In fixing the absorbent body, the pants-type disposable diaper in which the absorbent body is present only on the back body is manufactured by placing it on the side opposite to the side where the slit hole is formed without straddling the boundary in the folding process. Is done.

[Method for producing second-type pants-type disposable diaper]
Next, an example of a method for manufacturing the disposable diaper X2 of the second embodiment will be described with reference to FIG. Steps similar to those of the first embodiment of the diaper are omitted. This manufacturing process has the following processes instead of the process of forming the slit hole in the process of the diaper of the first embodiment.
In the process, first, as shown in FIG. 11B, in the process of supplying the continuous exterior sheet S, the hollow 1H is formed on one side with the width center of the continuous exterior sheet as a boundary. The hole 1H is formed by a cutter device, a punching device, or the like. Although not shown, it is preferable that the peripheral edge portion is subjected to a thermal fusion treatment, a thermocompression treatment, an ultrasonic welding treatment or the like simultaneously with or after the formation of the hollow hole.

Next, as shown in FIG. 11C, the sheet-like covering member 2 having the slit holes 1H is laminated on the continuous exterior sheet S so as to cover the hollow holes 1H. At this time, the extending direction of the slit hole 10 is set to be the width direction of the continuous sheet S, and the slit hole 10 is positioned in the cut-out hole 1H.
The two sheets can be joined by hot melt adhesive, heat fusion, thermocompression bonding, ultrasonic welding, or the like. The joining position is preferably the entire peripheral edge of the cut-out hole 1H.

  Here, in the example shown in the drawing, the sheet-shaped covering member 2 is formed by superimposing one longitudinal edges of two rectangular sheets 2A and 2B and bonding them at both longitudinal ends of the overlapping longitudinal edges. The sheet is formed into a single sheet, and the edge of the overlapping portion becomes the slit hole 10. When such a sheet-like covering member 2 is used, after forming the sheet-like covering member 2, for example, two rectangular sheets 2 </ b> A and 2 </ b> B are cut out in order, in addition to the method of stacking and joining the hollow holes 1 </ b> H. It is possible to adopt a method in which the sheet-like covering member 2 that is laminated in the hole 1H and consequently covers the hollow hole 1H is joined.

  Steps other than the step of forming the slit hole 10 are the same as the manufacturing method of the pants-type disposable diaper of the first embodiment, and the step of continuously supplying a continuous sheet ((A) in FIG. 11), leg After the step of forming the peripheral hole LH ((B) in FIG. 11), the step of fixing the absorber, the step of folding the continuous sheet S into two layers ((D) in FIG. 11), the side joint E 11 (E in FIG. 11) and the step of individually dividing ((F) in FIG. 11) are carried out continuously to perform the penis exposure shown in FIGS. The underpants type disposable diaper X2 concerning the 2nd form which has the slit hole 10 is manufactured continuously.

[Method for Producing Third-Type Pants-Type Disposable Diaper]
Next, an example of a manufacturing method of the disposable diaper X3 of the third embodiment will be described with reference to FIG. The same steps as those of the first and second diapers are omitted.
Also in this manufacturing method, first, the continuous exterior sheet S used as the exterior body 1 is continuously supplied in the line direction. In the illustrated continuous exterior sheet S, a group of a plurality of elastic elastic members 28s are spaced apart from each other about the center of the line width. This elastic elastic member 28s later becomes the elastic elastic member 28 around the thigh. Although not shown, the waist elastic elastic member and the like are also arranged at appropriate positions.
Then, in the process of supplying such a continuous exterior sheet S in the line direction, as shown in FIG. 12 (A), using a folding machine such as a holding machine, a butting portion T having the same surface butting at the center of the line width. The continuous exterior sheet S is continuously folded so that is formed. At this time, the butt portion T is set so as to be in a positional relationship where the elastic elastic members 28s arranged flat on the sheet face each other.

In the form of the illustrated example, the continuous exterior sheet S forms a butt portion T by Z-folding the center in the line width direction. For example, as shown in FIG. The part T can also be formed.
On the other hand, before or after or simultaneously with the step of forming the butt portion T, a slit hole 10 is provided on one side with the width center of the continuous sheet S as a boundary, as shown in FIG.

In the example shown in the figure, a method of joining the sheet-shaped covering member 2 having the slit hole 10 after forming the cut-out hole 1H is employed.
The slit hole is set at a position where it does not become the butted portion T. When the slit hole 10 or the cut hole 1H for the slit hole 10 is formed prior to the abutting portion T, the allowance for forming the abutting portion T in the continuous sheet S is considered in advance.

On the other hand, after at least the butted portion is formed, the absorbent body 3 is intermittently placed on the continuous exterior sheet S so as to straddle the opening side edge e2 of the butted portion T as shown in FIG. Fix it. When the absorbent body 3 is fixed to the sheet S, at least the portion of the sheet covered with the absorbent body 3 and preferably the absorbent core 33 is removed, and the opening edge e2 of the butted portion T is sealed and bonded with an adhesive or the like. Do not.
Next, as shown in FIG. 12 (C), one side of the continuous exterior sheet S is continuously folded back to the other side together with the absorber 3 with the opening side edge e2 of the butted portion T as a boundary, and is folded in two To. The folding of the continuous exterior sheet S can employ a sheet folding technique of a pants-type disposable diaper. One side or the other side at this time becomes the front body sheet 11F and the back body sheet 11B, respectively.

As shown in FIG. 12D, the continuous sheet S ′ that has been folded back has a convex joint Z ′ that is directed from the folded edge e1 of the butted portion T toward the folded edge 3e of the absorbent body 3 as shown in FIG. The sheet parts facing each other so as to be formed are joined by an adhesive means such as heat fusion, thermocompression bonding, or ultrasonic welding. The joint Ec is preferably a pitch joint. As a specific configuration of the joining portion, a known sheet edge joining technique can be appropriately employed.
The body surface sheet portions are joined together so that linear joining portions E ′ and E ′ are formed at positions between adjacent absorbers 3 and 3 before or after the formation of the convex joining portion Z ′. In the illustrated example, as can be understood from FIG. 3E, the formation of the main joints E ′ and E ′ and the convex joint Z ′ are performed simultaneously.
Of the joining steps of the convex joint Z ′ and the joints E ′ and E ′, at least after the convex joint Z ′ is formed, the folded edge Se (e1) of the continuous sheet S ′ is rolled. Cut or turn the cut edge with a cutter or the like. Preferably, it is performed after both steps of the respective joining steps of the convex joint Z ′ and the side joints E ′ and E ′.

When the folded edge Se (e1) of the continuous sheet S is cut, a part of the convex joint Z ′ remains. Then, at the same time as or after the cutting step of the folded edge Se (e1) of the continuous sheet S, the convex joint portion is cut into the concave notches while leaving the convex joint edges Zc to form the concave notches.
In the illustrated example, the one-dot chain line portion on the folding edge side of the continuous sheet S shown in FIG. 12 (F) is cut with a roll cutter, and the folding edge Se (e1) is cut and the recessed portion Z is simultaneously formed. I am doing so.

After passing through at least the side joining step among the joining steps of the convex joining portion Z ′ and the side joining portions E ′ and E ′, the absorber is maintained in the state where the joining at the position between adjacent absorbers is maintained. Divide into existing parts.
Thus, as shown in FIG. 12G, the trunks-type pants-type disposable diaper X3 shown in the third embodiment is continuously manufactured.
In the above manufacturing method as well, when forming the concave portion Z, the convex joint portion Z ′ is formed and then cut into the concave portion to form the concave portion Z. 3 is continuously folded back to the other side so as to be the inner surface, then cut into a concave notch from the folded edge Se (e1) toward the absorber edge 3e, and the concave notched edge is joined to A part may be formed.
In the step shown in FIG. 12B, the absorber 3 is sequentially and intermittently fixed in the line direction on the side where the slit hole is not formed with the opening side edge e2 of the butted portion T as a boundary. And the underpants type disposable diaper which has an absorber only in the back body is manufactured.

  Next, as shown in FIGS. 14C to 14D, the second continuous exterior sheet S2 is superposed on the first continuous exterior sheet S1. At this time, it is made for the absorber fixing | fixed part and opening part of each continuous exterior | packing sheet S1 and S2 to face. As a technique for continuously superimposing these sheets S1 and S2, a sheet laminating technique used for manufacturing a pants-type disposable diaper can be employed. In addition, the 1st continuous exterior sheet S1 and the 2nd continuous exterior sheet S2 at this time become the back body sheet 12 and the front body sheet 12, respectively.

  The continuous sheet S ′ in which the first continuous exterior sheet S1 and the second continuous exterior sheet S2 are overlaid and laminated is provided with an elastic elastic member group 28s as shown in FIG. The sheets are joined by means such as heat fusion, thermocompression bonding, and ultrasonic welding so that a convex joint Z ′ from the edge to the absorber edge is formed. The joining portion is preferably pitch joining. As a specific configuration of the joining portion, a known sheet joining technique can be adopted as appropriate.

The facing sheet portions are joined together so that linear joining portions E ′ and E ′ are formed at adjacent inter-absorber positions before or after the formation of the convex joining portion Z ′. In the illustrated example, as can be understood from FIG. 13E, the formation of the main joints E ′ and E ′ and the formation of the convex joint Z ′ are performed simultaneously.
These linear joint portions E ′ and E ′ are portions which become both side edge joint portions Ec and Ec of the front and rear bodies, and a known side edge joint formation technique of a pants-type disposable diaper can be employed. As specific joining means, for example, means of heat fusion, thermocompression bonding, and ultrasonic welding can be employed. Further, the specific configuration of the joint portion, for example, the width of the joint portion, solid joint or pitch joint is an appropriate design matter, and a known technique can be appropriately employed.
