Means for Solving the Problems The constitution of the present invention which has solved the above-mentioned problems is as follows: 1) A closed bag space is formed by an upper sheet and a lower sheet, and the whole or a part of the inner surface of the bag space is water-absorbing. 2) A disposable diaper in which a central portion of the upper sheet is opened to allow human waste to be accommodated in the bag space 2) An elastic body for contracting the periphery of the opening is provided in the upper sheet, and the upper sheet and the lower sheet The disposable diaper according to the above 1), wherein the passage through which the human waste enters is widened. 3) The disposable diaper according to the above 2), which is provided with an elastic body for contracting the side edge of the opening. 4) The bag space of the upper sheet. The disposable diaper according to any one of 1) to 3) above, wherein the sides and the outer side of the lower sheet are waterproof.

[0005]

According to the present invention, human waste excreted by humans is accommodated in the bag space through the opening. Since the buttocks are covered with the upper sheet in portions other than the opening, the stool stored in the bag space rarely adheres to the buttocks even if it adheres to the upper sheet. In addition, since loose stools and urine are stored in a bag-shaped space, they can be received so as not to leak even if they flow to the back or crotch portion, and spread between the upper sheet and the lower sheet, so that a large bag space is formed. Since water is absorbed by the area, it can be efficiently absorbed. The elastic body that contracts along the periphery of the opening is provided so that the opening is contracted so that the periphery of the opening is stretched so as to be in close contact with the buttocks and to surely guide the human waste to the bag space. When a waterproof sheet is provided on the bag space side of the upper sheet and the lower side of the lower sheet, the moisture absorbed by the outside of the upper sheet touching the buttocks with the waterproof sheet on the bag space side of the upper sheet In addition, loose stools and urine discharged into the bag space are easily spread between the upper sheet and the lower sheet, and moisture absorbed by the waterproof sheet outside the lower sheet is exuded. There is no.

[0006]
