DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body fluid-absorbing wearing article such as a disposable diaper, a sanitary napkin, a urine absorbing pad, etc., which is provided with a tape piece for rolling and discarding after use.

[0002]

2. Description of the Related Art In a disposable diaper disclosed in Japanese Utility Model Laid-Open No. 58-22908, an adhesive tape piece is attached to a back sheet. After use, the diaper can be rolled up so that the soiled area is not exposed and stopped with this piece of tape.

[0003]

The adhesive tape piece is
When attached to the rear waist area of the diaper, it is difficult for the infant wearing the diaper to reach, and the mischief of the infant is less likely to impair the adhesive function of the tape piece. However, doing so does not completely prevent the mischief of infants,
Sometimes the adhesive function is impaired. Further, when this tape piece is rubbed with clothing and peeled off from the back sheet, dust may be attached to the adhesive-applied area and the adhesiveness of the area may be impaired.

[0004] Therefore, an object of the present invention is to prevent a tape piece for rolling a disposable diaper or the like from being easily tampered with by an infant, and to prevent the tape from being easily peeled off by being rubbed by clothes. I have to.

[0005]

In order to solve the above-mentioned problem, the present invention is based on the premise that the present invention has a contact surface and a non-contact surface with the skin, and one end portion is formed on the non-contact surface. A body fluid-absorbing wearing article having a tape piece fixed and having a fastening area formed in a remaining free deformable portion including an end opposite to the one end.

On this premise, the present invention is characterized in that the tape piece is formed by a sheet covering at least a majority of the tape piece and a sheet forming at least a part of the non-contact surface. And at least a part of the accommodated portion is formed so as to be able to extend outward from an opening of the pocket, and when extended, the fastening area is formed outside the pocket to a part of the article. It is formed so that it can be fastened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the accompanying drawings, taking a disposable diaper as an example of a body fluid-absorbing wearing article.

FIG. 1 is a partially broken plan view of a disposable diaper viewed from the back side. Diapers are liquid-permeable topsheets 2
And a liquid-impervious back sheet 3 and a liquid-absorbent core 4 interposed between these two sheets. And a crotch region 8 located between the surrounding regions 6 and 7. The front and back sheets 2 and 3 extend from the periphery of the core 4 and are joined to each other,
Front and rear edge flaps 11, 12, right and left edge flaps 1
3, 14 and the left and right leg flaps 16 are formed. At the rear edge flap 12 and the left and right leg flaps 16, a waist elastic member 17 and a leg elastic member 18 are located between the front and back sheets 2, 3.
3 is adhered in an extended state to at least one inner surface.

In the rear waist region 7 of the diaper, a tape fastener 18 is provided on the side edge flap 14.
In the center between the left and right edge flaps 14, a pocket 21 opening toward the edge 12 is formed.
In FIG. 1, a discarding adhesive tape 22 that can be extended in the direction of the edge 12 as shown by the imaginary line is accommodated. The tape 22 is used when the dirty diaper is rolled up and discarded, and the details thereof will be described later. Pocket 2
1 is formed by joining a sheet piece 23 of a plastic film or a nonwoven fabric to the back sheet 3 at a sealing line 24.

FIG. 2 is a partial end view taken along the line II-II of FIG. The tape 22 includes a base end tape 26, a holding end tape 27, and an intermediate tape 28 located between these end tapes 26, 27. The base end tape 26 is adhered to the back sheet 3 and the intermediate tape 28 with an adhesive 31, and the intermediate tape 28 is adhered to the holding end tape 27 with an adhesive 35. These tapes 26, 27, 28 have an adhesive strength such that they do not substantially peel. Although the base end tape 26 and the holding end tape 27 are inextensible, the intermediate tape 2
8 is elastically or inelastically extensible up to 1.5 to 30 times, and when the tape 22 whose end 27 is pulled out from the opening of the pocket 21 is pulled, FIG. It extends like a virtual line of 2. An adhesive 32 is applied to at least a part of the lower surface of the intermediate tape 28, and the adhesive 32 is covered and protected by a release paper 33.

FIG. 3 is a side view of the diaper rolled using the tape 22. When the diaper is rolled so that the tape 22 is located on the outermost side, the tape 22 is extended, and
During the elongation process, the release paper 33 is peeled off, and the intermediate tape 28 is removed from the back sheet 3 at a position where the intermediate tape 28 exceeds the edge 12 of the diaper.
To stop.

FIG. 4 shows a pocket 2 for accommodating a tape 22.
1 is a rear-side plan view of a diaper according to one embodiment. In this diaper, a back sheet 3A covers the front waist region 6 and part of the crotch region 8, and a second back surface covers the back waist region 7 and the remaining part of the crotch region 8. And a seat 3B. First and second back sheets 3A, 3
B overlaps in the crotch region 8 and adheres in the region region 36 indicated by a number of dots, while the non-adhesion region 3
7 are formed, and the pockets 2 in which the first and second back sheets 3A and 3B open toward the edge 12 in the area 37.
1 are formed. In this example, since the pocket 21 is located in the crotch region 8, the tape 22 stored therein is
It is hard to be noticed not only by infants wearing diapers but by anyone, and it is also difficult to become a target of mischief between infants.

FIG. 5 is a view similar to FIG. 2 showing one embodiment of the tape 22. This tape 22 has an S-shape (inverted Z).
(Shaped). The tape 22 includes a base end portion 126 bonded to the back sheet 3 via the adhesive 31,
It is constituted by a non-adhesive gripping end 127 and an intermediate portion 128 between both ends 126 and 127.
An adhesive 132 is applied to the lower surface of the portion 128A adjacent to the holding end 127, and the adhesive 132 is applied to the portion 128A.
It comes into contact with the portion 128B of the intermediate portion 128 facing A in a releasable manner. When the tape 22 is pulled with the gripping end portion 127, the portion A and the portion B are peeled off and extend like an imaginary line. The dirty diaper can be rolled up with the topsheet 2 inside and stopped with an elongated tape 22.

In the present invention, the illustrated adhesive tape 22
Can be replaced with a tape having a mechanical fastener known as a trade name magic tape or the like. When using such a tape, use a non-woven fabric for the back sheet 3,
It is preferable that the tape can be fixed to an arbitrary portion of the back sheet 3. As a material of the tape 22, a plastic film or a nonwoven fabric can be used. When making the tape 22 elastic, a rubber sheet or a plastic elastomer film can be used. The objects using the tape 22 include disposable diapers, body fluid-absorbing wearing articles such as training pants, sanitary napkins, urine absorption pads, and blood absorption pads. When it is a diaper, it may be an open type as shown in the illustrated example or a pants type. As the members constituting the diaper, such as the top sheet 2, the back sheet 3, and the core 4, those commonly used in the art can be used.

[0015]

In the body fluid absorbent article according to the present invention, the tape piece used when the article is rolled up and discarded is accommodated in the pocket, so that the tape can be rubbed against a child's mischief, clothes, or the like. The fastening function of the pieces, for example the tackiness, is not impaired. When the pocket is formed in the crotch region of the diaper, the presence of the tape is not particularly conspicuous, and it is difficult for the child to be mischievous between infants.
