[0001]

[Industrial applications]

 The present invention relates to wearing articles such as disposable diapers, diaper covers, incontinence pants, and sanitary shorts.

[0002]

[Prior Art]

 Prepare an absorbent pad for absorbing body fluids and a wearing article such as disposable diapers, diaper covers, incontinence pants, and sanitary shorts separately, and apply this absorbent pad to the crotch region of the wearing article. The body fluid treatment means used are well known. It is desirable that this absorbent pad be stably held at a predetermined site of the worn article. For this purpose, for example, there is a conventional technique in which an absorbent pad is detachably attached to a wearing article with an adhesive, or the entire wearing area or the central area of the wearing article is made stretchable in order to press the absorbent pad against the body. is there.

[0003]

[Problems to be solved by the device]

 In order to absorb bodily fluids without using a single absorbent pad in this way, in addition to holding the absorbent pad in place, keep it firmly in contact with the body. It is desirable to keep. According to one of the above-mentioned conventional techniques, this problem can be solved for a while by wearing the wearing article in close contact with the body. However, there is a drawback in that the absorbent article may be separated from the body when the worn article, which is supposed to be in close contact with the body, slides down or loosens from the body.

On the other hand, the better the contact of the absorbent pad with the body by the pressure contact with the diaper, the less the air flow inside the diaper, which is one of the causes of stuffiness.

Therefore, an object of the present invention is to solve the above-mentioned drawbacks by attaching a band-shaped elastic holding member to the inside of a worn article from the front body to the back body under extension.

[0006]

[Means for Solving the Problems]

 The gist of this device to solve the above problems is as follows.

The present invention is premised on a wearing article for treating body fluids, which has at least a leak-proof sheet.

In such a wearing article, a belt-like elastic holding member is attached to the inside of the wearing article while stretching the belt-like elastic holding member from the front body to the back body.

In a preferred embodiment of the present invention, the band-shaped elastic holding member has a greater contraction force in the outer region than in the central region. Further, the band-shaped elastic holding member is composed of a plurality of members arranged in parallel, and in another preferred embodiment, the plurality of members are contracted in a member in an outer region than a member in a central region of the arrangement. I have increased my strength.

[0010]

[Action]

 In the wearing article according to the present invention configured as described above, the band-shaped elastic holding member contracts so as to straddle the crotch portion from the front body to the back body when it is worn, and is pressed against the crotch portion. By using this pressure contact, the absorbent pad applied on the elastic holding member can be pressed against the crotch portion.

By making the band-shaped elastic holding member have a greater contraction force in the outer region than in the central region, the absorbent pad has particularly good adhesion around the left and right legs.

If the band-shaped elastic holding member is a plurality of members arranged in parallel, it becomes easy to adapt the members to a complicated crotch shape.

【Example】

 The details of the present invention will be described below based on the embodiments.

FIGS. 1 and 2 are plan views showing the inside of a disposable diaper 1 which is an example of a wearing article according to the present invention. In FIG. 1, the diaper 1 is in a flattened state and a part thereof is cut away. FIG. 2 shows how the diaper 1 of FIG. 1 is in its natural state.

In FIG. 1, the diaper 1 has a front body 3, a crotch region 4, and a back body 5 when viewed in the longitudinal direction. When viewed in the thickness direction, the diaper 1 is composed of a water-permeable top sheet 6, a water-impermeable leak-proof sheet 7 constituting the back surface, and an absorber 8 interposed therebetween, and the top sheet 6 is The band-shaped elastic holding member 2 under extension is attached by joining only both ends 9, 10. The belt-shaped elastic holding member 2 is stretchable between the front body 3 and the back body 5 between both ends 9, 10. In addition to this, the diaper 1 includes elastic members 11 around the legs which are attached to the surface sheet 6 and / or the leakproof sheet 7 around the left and right legs while stretching, and a fastener tape 12 which is attached to the leakproof sheet 7 at the back body. And so on. When the diaper 1 is placed in a natural state, the belt-shaped elastic holding member 2 and the leg elastic members 11 contract, resulting in the state shown in FIG.

FIG. 3 shows a wearing state of the diaper 1. However, the diaper 1 is shown in a cross section along the center line in the longitudinal direction, and the wearer is not shown. An absorbent pad 20 is placed on the band-shaped elastic holding member 2, and the absorbent pad 20 is pressed against the crotch portion. The absorbent pad 20 is prepared separately from the diaper 1. The absorbent pad 20 that has absorbed body fluid and has become soiled can be discarded separately from the diaper 1, while the diaper 1 can be used repeatedly. In the diaper 1, a front body 3 and a back body 5 are overlapped around the waist and fastened by a fastener tape 12.

As shown in FIG. 3, when the diaper 1 is worn, the band-shaped elastic holding member 2 that is in contact with the crotch portion is deformed following its shape, and a contracting force acts between the joint ends 9 and 10. .. Therefore, the absorbent pad 20 adheres well to the crotch area. If the worn diaper 1 is then slightly slid down, the band-shaped elastic holding member 2 is changed to the position of the imaginary line 22 as an example. However, even in this case, the absorbent pad 20 can be kept in close contact with the crotch portion by the contraction.

FIG. 4 shows an example in which a band-shaped elastic holding member 22 made up of four thin members A and B is arranged in parallel. When the band-shaped elastic holding member 22 composed of a plurality of relatively thin members is used, it becomes easy to fit the absorbent pad 20 to the crotch having a complicated shape. Further, the contracting force of the member A arranged in the outer region can be made stronger than that of the member B in the central region of the array. By doing so, the adherence to the body is weak along the longitudinal centerline of the absorbent pad 20 that directly receives the excrement, and the adherence can be increased near the legs. Therefore, the local feeling of pressure can be softened to facilitate excretion, and the leakage of body fluid from the lateral direction can be effectively prevented. Such a configuration can also be applied to the band-shaped elastic holding member 2 shown in FIG. That is, in this case, it suffices to fold the outer region for increasing the contraction force inward and join at least the lengthwise opposing ends thereof. When a plurality of members A and B are used, it is possible to sandwich both sides of the absorbent pad 20 with two members on both sides thereof, and to fold both sides of the band-shaped elastic holding member 2 inward. If so, the pockets are formed in them, so that both side portions of the absorbent pad 20 can be inserted and clamped in these pockets.

When such band-like elastic holding members 2 and 22 are used in combination with a wearing article composed of a non-stretchable surface sheet 6 and a leak-proof sheet 7, it is particularly useful for bringing the absorbent pad 20 into close contact with the crotch area. It is valid.

As for the constituent members of the diaper 1, it is preferable that the band-shaped elastic holding members 2 and 22 are made of an elastic material having a large friction coefficient. The larger the coefficient of friction, the easier it is to hold the absorbent pad 20 at a predetermined portion. Specifically, sheets, films and fibrous materials made of natural rubber, synthetic rubber and various elastomers are preferable. Nonwoven fabric or perforated plastic film can be used for the surface sheet 6, and polyethylene film, other plastic film, rubber sheet or the like can be used for the leak-proof sheet 7. For the absorbent body 8, for example, a shaped product obtained by mixing crushed pulp and water-absorbing polymer powder is used. Known materials may be appropriately used for the leg elastic members 11 and the fastener tape 12. As the absorbent pad 20, for example, a shaped product obtained by mixing pulverized pulp and superabsorbent polymer powder, which is coated with a water-permeable nonwoven fabric and lined with a water-impermeable plastic film, can be used. Various adhesives including a hot-melt adhesive and a method of heat fusion can be used to join the strip-shaped elastic holding members 2 and 22 to the surface sheet 6. Other members may be joined to each other by using a conventional means.

Note that FIG. 1 shows an example in which two absorbers 8 are symmetrically arranged and no absorber is provided in the middle thereof. If the absorbent pad 20 has sufficient absorbing power, the diaper 1 may not include the absorbent body 8 in some cases. However, the diaper 1 shown in FIG. 1 is provided with an absorber 8 along the side edge in preparation for an unexpected side leakage. In this example, the absorbent body 8 is divided into two parts on the left and right sides in order to save the material and prevent the absorbent pad 20 from undesirably protruding in the worn state. The absorber 8 may be formed in a thin central region without being divided into two parts, or may be provided in a desired portion as appropriate. Further, the strip-shaped elastic holding members 2 and 22 joined to the topsheet 6 may be attached to the topsheet 6 or the leakproof sheet 7 depending on the structure of the diaper 1, for example, when the topsheet 6 and / or the absorber 8 are not provided. Can be directly joined.

Although not disclosed, as the absorbent pad 20, one having a thin absorbent material on both sides thereof or a flap on which the thin absorbent material is not disposed is used. Sometimes.

[0023]

[Effect of the device]

 The absorptive pad can be brought into close contact with the crotch part by the contracting force of the band-shaped elastic holding member provided from the front body to the back body. Such close contact can be maintained even if the diaper is slightly slipped.

Moreover, in such a worn state, since a gap is formed between the bottom surface of the absorbent pad and the inner surface of the diaper that faces the absorbent pad, stuffiness in the diaper is less likely to occur. By the way, there is a significant difference in that such an air gap is generated, compared with the case where the elastic member is directly attached to the entire area or the central area of the diaper.

By using the band-shaped elastic member composed of a plurality of members, it becomes easy to bring the absorbent pad into close contact even with a complicated shape of the crotch.

By making the contraction force of the band-shaped elastic holding member different, it is possible to soften the local feeling of pressure and to effectively prevent body fluid from leaking from around the legs.
