Abstract

(57) [Summary] [Purpose] A disposable diaper is provided with a stool reservoir to prevent the spread of stool. [Structure] In the crotch portion 13 of the disposable diaper 1, a toilet bowl 7 composed of a recess 20 and a raised portion 21 is provided in the absorbent body 4, and the topsheet 2 is made to conform to the shape of the toilet bowl 7. By wearing the diaper 1 so that the toilet bowl 7 is located near the anus, the feces can be guided to the toilet bowl 7 and its spread can be suppressed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a disposable diaper.

[0002]

[Prior Art]

 Conventionally, many disposable diapers are constructed by interposing an absorbent body between a liquid-permeable top sheet and a liquid-impermeable back sheet. As the absorber, a mixture of ground pulp and superabsorbent polymer shaped into an hourglass shape or a rectangular shape is often used.

[0003]

[Problems to be solved by the device]

 Since such an absorber and the surface sheet covering it are made flat, it is unavoidable that excreted feces spread widely in the diaper's inseam, so that the diaper wearer's inseam to buttocks / waist area. It is inevitable that a wide range will be contaminated.

Therefore, the present invention has an object to suppress the spread of such feces by providing a feces reservoir in the absorbent body.

[0005]

[Means for Solving the Problems]

 The gist of the present invention to solve the above problems is as follows.

The present invention is premised on a disposable diaper including a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorbent body interposed between these sheets.

On this premise, a feces reservoir is provided in the crotch region of the absorbent body, and the feces reservoir defines a concave portion recessed from the upper surface of the absorbent body and a ridge protruding from the upper surface to define a peripheral edge of the concave portion. It is a feature of the present invention that it is formed from a raised portion.

[0008]

[Action]

 In the disposable diaper thus configured, the recess surrounded by the ridge is located near the anus, and the excreted feces are received here, and the spread of the feces is suppressed. The stool basin has a raised part around it, and by applying this part to the buttocks, the stool is guided to the stool so that it does not escape to the side during excretion.

【Example】

 The details of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view of a disposable diaper 1 according to the present invention. The diaper 1 is provided with a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, and an absorbent body 4 interposed between the two sheets 2 and 3. In addition, the diaper 1 is stretched between the two sheets 2 and 3 on the inner sides of both sides. The leg elastic member 5 attached below and the connecting tapes 6 provided on both side edges of the rear body 14 are provided. The longitudinal direction of the diaper 1 can be roughly divided into a front body 12, a crotch portion 13, and a back body 14, and in the crotch portion 13, a toilet bowl 7 is provided on the surface of the absorbent body 4.

FIG. 2 is a sectional view taken along the line II-II of FIG. 1 and shows the details of the toilet bowl 7. The absorbent body 4 is provided with a substantially circular toilet bowl 7 in the widthwise center of the diaper 1. The toilet bowl 7 is formed from a concave portion 20 having a thickness A at the bottom surface which is recessed from the upper surface of the absorbent body 4, and a raised portion 21 protruding from the upper surface of the absorbent body 4 and defining the peripheral edge of the concave portion 20. And the outer peripheral portion 22 extends substantially flat. The thicknesses A, B and C of the respective parts are B> C ≧ A. The toilet bowl 7 is formed by shaping the absorbent body 4 in such a manner, while the topsheet 2 is shaped, or is made slack to conform to the shape of the absorbent body 4. Therefore, if necessary, the back surface of the top sheet 2 and the front surface of the absorber 4 can be joined intermittently so that the top sheet 2 does not move unnecessarily.

When the diaper 1 configured in this manner is worn so that the toilet bowl 7 is located at the anus, most of the excreted feces can be retained here and its spread can be suppressed. Since the peripheral edge of the concave portion 20 is raised by providing a raised portion 21, the raised portion 21 easily adheres to the buttocks so as to seal around the anus, and the feces are effectively placed in the concave portion 20 so that the feces do not escape sideways. You can lead in. The planar shape of the recess 20 is not limited to the circle shown in the drawing, but may be an appropriate shape such as an oval or a rectangle.

To provide the toilet bowl 7 in the absorbent body 4, a raw material such as crushed pulp is sprinkled and supplied onto a forming die having the shape, and the shape is copied or a web having a predetermined thickness is formed. There are methods such as pressurizing with a mold and shaping, and if necessary, the raw materials can be processed in a wet state or a heated state. For the diaper 1, other known materials can be used for the other constituent materials and the means for assembling them. It is more preferable that the raised portion 21, that is, the portion having the thickness D on the upper surface of the absorber 4 is more flexible or has higher compression elasticity than the other portions of the absorber 4.

[0014]

[Effect of the device]

 In the diaper according to the present invention, since the feces are provided in the crotch part, the feces are prevented from spreading to the crotch part, the buttocks and the waist part, and the wearer's body is not soiled.
