DESCRIPTION OF THE PREFERRED EMBODIMENTS An article according to the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show a pants-type diaper. The diaper 1 includes front and rear bodies 1a and 1b. The front and rear bodies 1a, 1b are defined by a waist upper edge 2, both outer edges 3, a crotch protruding edge 4, both inner edges 5, and a leg lower edge 6, and a trunk covering portion. 7 and a leg covering portion 8 extending downward. Even if both outer edges 3 are inclined with respect to the longitudinal axis 9 so that the body covering portion 7 becomes wider downward, even if the both inner edges 5 are vertical lines parallel to the longitudinal axis 9, The lower edge 6 around both legs may be a horizontal line orthogonal to the vertical axis 9. The front and rear bodies 1a, 1b are substantially the same as the inner and outer sheets 10, 11 in contour between the liquid-permeable inner sheet 10, the liquid-impermeable outer sheet 11, and the inner and outer sheets 10, 11. , And formed smaller than the inner and outer sheets 10, 11 in the size of the contour,
The interposed liquid-absorbent panel 12 and the outer peripheral edges 10a of the inner and outer sheets 10, 11 extending from the outer peripheral edge of the panel 12.
Elastic members 13 and 14 are attached between the sheets around the waist and both legs of the base 11a while extending in the lengthwise direction. Further, the outer peripheral portion 1
Nos. 0a and 11a are fusion-bonded under heating or under the action of ultrasonic waves while leaving their edges slightly. Such front and back body 1a,
1b is formed by fusion bonding under heating or ultrasonic action along the outer edges 3, the inseam protruding edges 4 and the inner edges 5 while leaving them slightly. An opening 16 is formed.

As shown, the joining line 17 along both outer edges 3 may be intermittent in order to separate the front and rear bodies 1a and 1b by tearing after use of the diaper and to improve the air permeability. Preferably, the joining line 18 along the crotch ridge 4 and the inner edges 5 is continuous, as shown.
It is preferable in preventing leakage of excreted liquid.

The front and rear bodies 1a and 1b extend downward from the crotch base 19 to the crotch between the leg covering portions 8 and extend upwardly.
An arc-shaped protruding portion 20 defined by the above is formed. The pockets 21 are formed by joining the protruding portions 20 of the front and rear bodies 1a and 1b at the joining line 18. The depth of the pocket 21,
That is, the dimension D from the crotch base 19 to the deepest bottom of the pocket 21 is preferably at least 5 mm in order to introduce and hold the stool in the pocket 21, but if the maximum dimension is up to about 80 mm, it is worn. Since it does not hinder the walking of the person or significantly impairs the appearance, it may be appropriately determined within the range according to infants and adults. Even in the case of this maximum size, it is not preferable that the lower end of the protruding portion 20 protrudes too much from the lower end of the leg covering portion 8.

FIG. 3 shows an open type diaper. The diaper 1A according to this embodiment includes a front and rear body 1a,
The configuration is the same as the diaper 1 according to the above-described embodiment, except that the diaper 1 is not joined, and the back body 1b is formed wider than the front body 1a in width.

The diaper 1A is provided with tape fasteners 22 coated with a plurality of pressure-sensitive adhesives on the inner surface thereof as fastening pieces on both sides of the back body 1b at intervals in the longitudinal direction of the back body 1b. Are connected to both sides of the front body 1a. Of course, front and back body 1a, 1
b may be formed in the same manner. Even in such a case, as long as the width is appropriately formed, the front body 1
The same connection can be made in a state where both sides of the back body 1b are overlapped on both sides of the body a.

FIG. 4 shows a diaper 1B according to still another embodiment.
Shows the crotch. The diaper 1B according to this embodiment uses continuous inner and outer sheets 10, 11 of the front and rear bodies 1a, 1b. A portion 23 is formed and joined along a concave edge 24 at a joining line 25. In this embodiment, the bottom of the raised portion 20 is not required to be joined because it is a fold of the continuous sheet, but this is also referred to as "joined along the raised edge" in the claims of the present invention. It should be understood that it is included.
In order to form the leg opening 16 at an appropriate angle, the lower edge of the folded continuous sheet, which is a folding line, is cut.

The inner sheet 10 is preferably a nonwoven fabric, preferably at least a stretchable nonwoven fabric in the width direction, and the outer sheet 11 is a stretchable nonwoven fabric at least in the width direction, and the same stretchable elastomer film is laminated on the inner surface.
Is a mixture of fluff pulp and superabsorbent polymer, elastic members 13 and 14 have rubber elasticity such as natural or synthetic rubber, and tape fastener 22 is a laminate of a high-quality paper or nonwoven fabric and a plastic film. Can be used.

In the case of the diaper 1A shown in FIG. 3, a plastic film is applied to the region of the front body 1a where the adhesive application portion of the tape fastener 22 is adhered so that the application portion can be repeatedly adhered to the region. You may be wearing it.

[0019]

According to the present invention having the above configuration,
When the wearer stands up and wears the stool, the stool hangs down from the wearer's crotch, so that the stool can be smoothly introduced and held in the pocket formed by the swell. Even when the wearer is lying down and wearing the stool, the stool flows into the space where the space is generated without contacting the wearer's skin, and is often introduced and held in the pocket. Even when the article is worn with the crotch base pulled up so that the crotch base abuts on the wearer's crotch, the wearer's crotch does not come into contact with the stool staying in the pocket and does not get dirty.

The raised portion also serves as a positioning when the article is properly worn by a wearer. This is particularly effective when the article is an open diaper.

When dumping used diapers, it is preferable to remove stool from the viewpoint of public health. At this time, the stool held in the pocket can be easily removed by pushing the protruding portion / pocket so that the bottom surface thereof protrudes inward and inverting the inner and outer surfaces, which is extremely convenient.

When the liquid-absorbent panel is interposed between the front and rear body including the raised portion / pocket, the absorption area of the crotch is increased by the inner surface of the pocket, and the absorption capacity of excreted liquid is increased.
