Embodiment Construction

[0010] Hereinafter, the disposable diaper of the present invention will be described in detail with reference to the drawings.

[0011] Fig. 1 is a partially cutaway perspective view of a disposable urinal. The diaper consists of a laminated sheet 1; the sheet 1 has a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, an absorbent core 4 interposed between The liquid-repelling first leak-proof layer 5 extending in a ring shape, and the liquid-repelling second leak-proof layer 6 extending in a ring shape coexist with the first leak-proof layer 5 on the outer side of the top layer 2 . The sheet body 1 has a front waist region 20, a rear waist region 22, and a crotch region 21 between the front and rear waist regions 20 and 22 in the longitudinal direction; The side edge portions 1a drawn in an arc inwardly and the front and rear end edge portions 1b, 1c facing each other and extending in the lateral direction. A pair of liquid-repellent side layers 17 extending i...

Abstract

In order to provide a disposable diaper that can prevent excreted urine and feces from being mixed and avoid uncomfortableness. A diaper is constituted of a laminated panel made by interposing a core between a top sheet and a back sheet and providing a first leakage barrier sheet extending in an annular shape on an outer face of the top sheet, and has a first opening 8 in an approximately central part of the first leakage barrier sheet. The first leakage barrier sheet is located at a rear half part 1e of the panel and a second leakage barrier sheet 6 is located at a front half part 1d of the panel and a second opening is defined in an approximately central part of the second leakage barrier sheet.So that urine discharged into the second opening may be absorbed by the core through the topsheet and feces discharged into the first opening may be absorbed by the core through the topsheet.

Description

technical field [0001] The present invention relates to a disposable diaper which absorbs and retains excreted body fluids. Background technique [0002] Japanese Patent Laying-Open No. 5-277149 discloses a disposable diaper having a liquid-permeable top sheet, a liquid-impermeable back sheet, a liquid-absorbent core sandwiched between the two layers, a circularly extending In the liquid-repellent leak-proof layer, the outer periphery of the leak-proof layer is joined to the upper surface of the top layer, and a longitudinally elongated opening is formed in the approximate center of the leak-proof layer, and an elastic member stretchable in the longitudinal direction is attached to the periphery of the opening of the leak-proof layer. The diaper can prevent excrement from leaking from the diaper side edges and the front and rear end edges because the leak-proof layer extending in a ring is installed on the top layer. [0003] The diaper shown in JP-P-5-277149 communiqué can...
