Embodiment Construction

[0025] Hereinafter, the present invention will be described with reference to the drawings.

[0026] like figure 1 As shown in (A), the diaper 11 is comprised by the sandwich structure which sandwiched the absorbent core 14 between the backsheet 12 and the topsheet 13 . The back layer 12 faces outward when the diaper 11 is worn, and is formed of a liquid-impermeable and air-permeable resin layer or the like that does not leak moisture such as urine to the outside. In addition, the surface sheet 13 faces the wearer's skin and is in direct contact with the wearer's skin, so it is composed of a liquid-permeable nonwoven fabric or a porous resin layer that allows the collected urine to pass through the absorbent core. In addition, the absorbent core 14 absorbs urine or the like which has passed through the top sheet 13, and is therefore made of pulverized pulp with good water absorption, or a mixture of pulverized pulp and a superabsorbent polymer, or the like.

Abstract

Thin thickness parts are formed in the absorption core present in the front waist region and the back waist region of a diaper. The thickness of the diaper at the thin thickness part is preferably 1/2-fold or less the thickness of the absorption core at the thick thickness part in the crotch region. When the diaper is folded along a line parallel to the longitudinal direction of the diaper, the front waist region and the back waist region are folded at the thin thickness parts to overlay the thin thickness parts together. Thus, the thickness of the front waist region and the back waist region when folded along the folding line is the same as the thickness of the thick thickness part. Therefore, the thickness of the folded diaper can be made thin, with no reduction of the thickness of the absorption core in the crotch region where urine is mainly absorbed.

Description

technical field [0001] The invention relates to a diaper which can be folded into a small size and put into a bag, and the folded thickness is thin, small and convenient for transportation and portability. Background technique [0002] Disposable diapers are composed of a back layer and a surface layer, and an absorbent core interposed between these two layers. The aforementioned back layer faces outward when the diaper is worn. It is composed of a liquid-impermeable and air-permeable resin layer that is impermeable to urine and the like. In addition, since the surface layer faces the wearer's skin and directly contacts the skin, a liquid-permeable nonwoven fabric, a porous resin layer, or the like is used as the surface layer. Furthermore, the absorbent core absorbs urine passing through the surface layer, and a mixture of pulverized pulp and a superabsorbent polymer is used. [0003] The above-mentioned absorbent core is pressed to make the thickness uniform, cut into a...
