The specific embodiment

To be that example is described every content of the present invention and embodiment such as disposable absorptive articles for use such as sanitary towel or disposable diapers with one below.Yet clearly, the present invention is equally applicable to such as medicated cap, operating coat, spat, fem-care, children training trousers, incontinence garment or the like.Usually, disposable product is designed to and only limits to once use and do not plan washing or reuse after the cleaning in addition.For example, a disposable diaper is abandoned after being polluted by the wearer usually.

Figure 1A is to having vertical 26, the cross-sectional direction 24 of a length direction and the centrage 40 of a longitudinal extension such as the such articles for use of sanitary towel 10 (or Fig. 2 A is to the disposable diaper 10 ' shown in Fig. 2 B) shown in Fig. 1 E.These articles for use comprise that one first articles for use part, second articles for use part and at least one are used for first articles for use partly are fastened on securing member 36 on second articles for use part.This fixed form be designed to can be whereby and, for example, articles for use are fixed on one's body the wearer.This securing member requires to comprise at least one first secure component 70 and a cooperation secure component 72, on the appointed part of this first secure component 70 attached to first (or second) articles for use part, this cooperates secure component 72 attached on second (or first) articles for use part.The first tight state parts 70 comprise a bonding land, and this bonding land has a plurality of joint elements 56.Each joint element 56 has a stem 58, and this stem 58 has a remote area 44 and has at least one and is arranged on retaining element 60 in its respective distal end zone.The retaining element of these a plurality of joint elements 56 has a kind of spread geometry.Be contemplated that the spread geometry of the retaining element of used a plurality of described joint element 56 can have nothing in common with each other on the articles for use.

Another aspect of the present invention can provide a kind of articles for use, and secure component wherein can comprise a bonding land, and this bonding land has a plurality of non-isotropic joint elements.Wherein each non-isotropic joint element can have a stem 58 and the retaining element 60 with directivity that has distal portions 44, be arranged on the remote area of its corresponding stem 58, so that a non-isotropic connector to be provided these retaining element 60 non-isotropies.The connector of described a plurality of non-isotropic joint elements can have a kind of spread geometry.Be contemplated that, can use a plurality of so non-isotropic joint elements, and the spread geometry of the connector of these non-isotropic joint elements can have nothing in common with each other.

In concrete structure, the direction of the connector of most of non-isotropic joint elements is substantially normal to it and adheres to direction.In general, the described direction of adhering to is meant in the articles for use that corresponding first and second portion are incorporated into together in an overlapping and the direction of the relation of being bonded with each other.In Fig. 1 and Fig. 2, adhering to direction is such direction substantially, and this direction has one transversely 24 and towards the horizontal vector component of articles for use centrage 40.Therefore, the connector direction of a plurality of non-isotropic joint elements is arranged essentially parallel to the centrage 40 of articles for use.

In various aspects of the present invention, one joint element all is soft and resilient usually, but they will keep its initial shape basically in normal the use.When during normal use bending or being out of shape, plastic deformation can not take place and keep the distortion that is suffered in joint element basically, but returns to or spring back to its initial direction and shape basically.

Each side of the present invention (individual event and compound) can help articles for use are fitted on one's body the wearer better.For example, each side of the present invention can help to reduce the sagging of medicated clothing crotch region and have a down dip, and can help to reduce the clot of lumbar region and have a down dip.The each side of incorporating fastening system of the present invention into can be improved the fixed performance of articles for use, make the fastening system of articles for use have the bigger ability that collapses out in early days of resisting, also can improve the suitability of articles for use, make it have bigger comfortableness and reduce its zest wearer's skin.

Articles for use of the present invention can be, for example, and disposable diaper.Of the present invention required aspect in, first articles for use of these articles for use part can be the i.e. back waistband portion of one first waistband portion, and its second articles for use part can be that one second waistband portion is the front waist belt part.In addition, these articles for use can also have a mid portion or a title crotch portion that is connected between this first and second waistband portion.This diaper can comprise that also the top flat layer of the liquid thoroughly that a backsheet layer, one and this backsheet layer are opposed and coupled and one are such as the absorbent structure that includes the moisture absorption body.This absorbent structure is clipped between this backsheet layer and the top flat layer, and operationally is fixed on therebetween.Between first waistband portion and second waistband portion, be provided with one usually and these two waistband portion coupled together, articles for use are fixed on one's body the wearer such as the fastening system that includes securing member.This fastening system can be designed to effectively, in dress, with first waistband portion promptly the back waistband portion from after to overlap onto second waistband portion forward be that front waist belt is partly gone up and the two is coupled together, thereby make the two health that surrounds the wearer and diaper be fixed on one's body the wearer.Alternative is, the used securing member of this fastening system also can be designed to, and in dress, the front waist belt part is overlapped onto on the waistband portion of back in the past backward and the two is coupled together diaper is fixed on one's body the wearer.In such constructive alternative, the front waist belt zone can be regarded as first waistband portion then waist area can be regarded as second waistband portion.

Figure 1A is depicted as a typical hygiene towel to Fig. 1 E, and this sanitary towel has the flap or the fin 36 of fastener forms.Wherein have one first secure component 70 at least attached on flap or the fin 36, and have at least one to cooperate secure component 72 attached on opposed flap or the fin 36.In certain embodiments of the present invention, be attached with first secure component 70 on each flap simultaneously and cooperate secure component 72, the concrete overlapping order that so just needn't haggle over two flaps just can tighten up the two.In another embodiment, flap can form whole or a part of cooperation secure component 72.Sanitary towel shown in Fig. 1 C centers on two flap or fin 36 and is fixed on underwear or the underpants " P ".Arrow among the figure " A " is generally represented to adhere to direction, and arrow " 0 " ordinary representation adheres to the orthogonal direction of direction.Should be appreciated that this orthogonal direction should be thought of as basically along articles for use usually or drops on the articles for use plane, although this orthogonal direction comprises a very little Z durection component under some specific occasion.

According to the present invention, first secure component should be designed to have a maximum axis that engages.This can finish by the joint element 56 that adopts a plurality of non-isotropies (that is anisotropy) or asymmetry.When the maximum engagement axis with first secure component is orientated to and adheres to direction (also be about to each secure component roughly gather together to implement the overlapping direction that is connected) roughly during quadrature, be surprised to find that the be bonded with each other situation of this fastening system in wearing process seems better.For example, measure peeling force and tangential force with the test instrunment of standard, adhere on the direction if the maximum engagement axis of first secure component is arranged in, the measured value of the peeling force of fastening system and tangential force is bigger before the articles for use dress so; If adhere to direction and the maximum engagement axis of first secure component is arranged as to be orthogonal to, measured peeling force and the tangential force of fastening system is less before the articles for use dress so.

But after articles for use were worn, the peeling force of two kinds of aligned fastening systems and the measured value of tangential force had all improved.Yet the maximum engagement axis of first secure component is arranged as and is orthogonal to the measured peeling force and the tangential force of fastening system of adhering to direction and but is arranged in the measured peeling force and the tangential force of fastening system of adhering on the direction greater than the maximum engagement axis of first secure component.

The particular content of standard test procedure is that attempt generates the fastening condition that can represent the operating position of user better.In the preparation test piece (for example, hook and loop type material) when measuring in the typical construction of the present invention collaborative peeling force that produces and/or shearing force, should be noted that the width dimensions of selected test piece material should be corresponding along the size of articles for use vertical 26 with the fastener material in the actual articles for use.The length dimension of equally, selected test piece material should be corresponding along the size of articles for use horizontal 24 with the fastener material in the actual articles for use.

It is desirable to, the intensity that is fastenedly connected between first secure component and the cooperation secure component should be enough to prevent that parts from bearing so tensile time spent generation drop out of gear of doing, this tensile size is at least about 1,000 gram force, it applies direction for transversely outwards and be roughly parallel to the backsheet layer plane of articles for use.

The fastener-parts of various structures of the present invention and tightening member can adopt any or multiple adhering mode to be attached in the substrate suitably, and this class adhering mode has been used for constructing the multiple miscellaneous part of articles for use of the present invention or different parts are fixed together.Tightening member in the zones of different can be used such as model, method such as coextrusion and form along their relevant basal layeres are whole.Basal layer and relevant mechanical tightening component can form with substantially the same polymeric material, and needn't be ad hoc one independently operation tightening member is attached to originally on the isolating basal layer.For example, can come integrally to form simultaneously hook element and hook basal layer with essentially identical polymeric material with coextrusion process.

Be understood that easily, but the intensity of fixing or other connections between basal layer and the accompanying secure component should be greater than in order to draw back required peak force to fastening flaps 36 from the fixed specified articles for use parts of its releasable.

Generally speaking, if the flap of personal-care supplies or fin adopt quite softish material to make, a problem just can appear in a part that is used as the releasable fastening system that is bonded with each other of selectivity with this flap or fin so.The flexibility of height can make nursing materials be easy to use, be easy to fastening and also be easy in some cases make.Yet,, will cause occurring undesirable gauffer, pack and/or inefficacy in the time of so on fastening system is worn if it is undue nonelastic, soft and/or lax to be used as the flap or the fin of a fastening system part.

According to one embodiment of present invention, first secure component of a flexibility extends across on the longitudinal size at least or direction of a relative more softish flap or fin, and this helps to alleviate flap and turns round and too soft, the nonelastic and/or shortcomings such as lax gauffer that causes and fastening inefficacy because of the securing member attachment systems because of beating of causing on being worn.Generally speaking, first secure component should be than the flexible material of making flap, fin firmer (that is flexibility be hanged down slightly).One of advantage of this structure is shaken and seismism for flap or fin less may generation by high-speed production lines and/or baling line time of incorporating first secure component into.

The relative flexibility of the flexible material of first secure component and making flap or fin can be measured with the hardness test of dangling of routine.This test is known to the professional and technical personnel and is easy to carry out.As an example, can by measure earlier make flap or fin material the standard size test piece (for example, 10 centimetres of 10 cm x, 15 centimetres of 15 cm x or the size that some is similar) the hardness of dangling, the hardness of dangling after measuring this test piece again (on resembling attached to product time direction) adhering to last first secure component substantially continuously on vertical direction at least, thus its relative flexibility assessed out.Although the conventional test of dangling all is to be used for assessment material to perpendicular to the resistance of the deflection that power caused of material plane usually, but with regard to purpose of the present invention, can be used for assessing such as the flap in the personal-care supplies such as sanitary towel or fin resistivity to the distortion power that run in the normal use by the test of dangling of the routine relative performance of the material a kind of good approximation method of can yet be regarded as of measuring and monitoring the growth of standing timber.

(for example discussing first secure component and articles for use flexible portion, form the articles for use part of flap or fin) relative flexibility the time, used " more soft relatively " speech is meant flexible portion (or material) and is attached with the difference that this flexible portion (or material) of first secure component dangles in testing in routine and is at least about 10%.It is desirable to, it is about 25% that this difference is at least, and better is that this difference is greater than 50%.In certain embodiments, this difference is thought of as greater than 100%.Consider can be greater than 250% for this difference in other embodiments, even greater than 500%.

In addition, be that first secure component that a flexibility is set on longitudinal size or the direction can be avoided in flap central authorities a little caused problem of isolated first secure component being set at least at relatively more softish flap or fin.Little isolated first secure component 100 is positioned at the central authorities of flap or fin 36 among Fig. 9.Such fastening system just can cause a moment 110 of changeing around securing member 100 (this securing member resembles an axle) when having a power 120 that is orthogonal to longitudinal size or direction to act on the securing member in the normal use at articles for use.This moment causes flap to be beaten usually turning round and frills, and tends to make the suitability of the personal-care supplies that adopt this fastening system to reduce.It is too little or do not have rigidity to come the moment of negative function on little isolated secure component 100 to beat the reason turn round with the pack phenomenon and be the rigidity of flap.

Figure 10 shows that same normal force 120 appears at constructional situation of the present invention.In this structure, it is on vertical (" L " direction among the figure) size or the direction at a relative more softish flap or fin 36 at least that first secure component 70 of a flexibility extends across basically.When moment 110 produced, " successive basically " first secure component 70 that is on the tram can reciprocal static force 130 of generation be offset this moment.With same structure but do not adopt first secure component 70 of " continuous basically " but adopt little isolated first secure component, 100 displaced personal care absorbent sex aids to compare, the flap in the personal care absorbent sex aids of the present invention is beaten and is turned round and crimped phenomenon has reduced.

Just should be understood to when describing one first secure component 70 for " continuous basically " that this secure component 70 extends across basically is vertically on (" L " direction) size or the direction, as shown in figure 10 at flap or fin 36 at least.Certainly, can consider to make this first secure component roughly to extend in laterally (that is perpendicular to vertically the direction of " L ") of flap or fin 36 and cross over whole flap or fin 36.It is also conceivable that make this first secure component not only roughly extended in flap or fin 36 laterally but also extend across basically flap or fin 36 vertically to cover whole flap or fin.For example, this structure can form a solid square patch, hollow square patch, " X " shape or the figure of other types or the patch of shape.Here alleged " continuous basically " speech is meant that first secure component extends to another side from one side of flap or fin 36 always, and first secure component extends to from another a distance, edge from a distance, an edge from flap or fin 36 always.It is desirable to, this first secure component roughly extends on 50% the longitudinal length of flap at least.Alternative is, this first secure component can roughly extend on 50% the lateral length of flap or fin in addition at least.Better is, this first secure component roughly extends at least 75% vertically and/or on the lateral length of flap.Better again is, this first secure component roughly extends at least 90% vertically and/or on the lateral length of flap.This first secure component can be formed by the first secure component section independently, and this secure component section extends to another edge from an edge of flap or fin haply always and is still " continuous basically ".Although showing among Figure 10 has two flaps 36, only showed first secure component 70 of " continuous basically ".Should be appreciated that on two flaps to be provided with first secure component, for example, as shown in Figure 1.It is also conceivable that one, big flap or fin material only are set in the articles for use that this one big flap material is connected by the flexible portion of fastening system with the personal care absorbent sex aids.

According to an aspect of the present invention, these characteristics can be used to provide a kind of articles for use with the releasable fastening system that is bonded with each other of selectivity, these articles for use have a length direction vertically, a cross-sectional direction, the centrage of a longitudinal extension, first articles for use part and one second articles for use part.This fastening system comprises:
