Pants-type disposable diaper

Abstract

To realize a shorts type disposable diaper enabling easy putting and wearable suitably. This paper diaper (1) comprises an external sheet (20) having a waist elastic band (25a) formed of a plurality of waist elastic members (25) disposed on a front body portion (F) and a rear body portion (B) starting at one joining end parts (21, 22) thereof to the other joining end parts (21, 22) thereof, curved elastic bands (26a, 28a) formed of a plurality of curved elastic members (26, 28) disposed on the front body portion (F) and the rear body portion (B) starting at one joining end parts (21, 22) thereof to the crotch part (20c) side thereof and, after bypassing the crotch part, further to the other joining end parts (21, 22) thereof, and an absorbable body (10) disposed at the crotch part (20c). The curved elastic bands (26a, 28a) are formed to roughly cover the entire area (Trf, Trb) of the external sheet which is surrounded by the edge parts of the external sheet (20), the absorbable body (10), and the waist elastic band (25a).

Description

technical field [0001] The present invention relates to a pants-type disposable diaper with improved wearability and fit. Background technique [0002] Conventionally, in underpants-type disposable diapers, in order to fit an absorbent body that absorbs body fluids on the body, an elastic stretchable member is disposed on an outer sheet that holds the absorbent body to improve the fit to the body. [0003] For example, as shown in FIG. 21 , in the diaper main body 50 in which the absorber 40 is interposed between the front panel and the rear panel, there is known a pants-type disposable diaper including a waist elastic member 51 and leg elastic members 52, 52 . . . The waist elastic member 51 is arranged on the front body 50F and the back body 50B which form the waist opening; the leg elastic members 52, 52... are respectively arranged from the front body 50F and the back body 50B to the crotch 50C. The substantially central side of the diaper is curved in a convex shape, a...

[0007] However, in the case of the above-mentioned Patent Document 1, since the leg elastic members 52 are arranged along the edge of the diaper main body 50 forming the leg openings, the leg openings can be opened by the contraction force of the leg elastic members 52 . Suitable for the wearer of a diaper, but surrounded by the leg elastics 52, the waist elastics 51 and the absorbent body 40, the substantially triangular region Tr in the outer sheet consisting of the front panel and the back panel, surrounded by the leg elastics 52 and the waist elastic member 51 are contracted so that the inside of the roughly triangular region Tr has a raised shape in the finished state, thereby forming a pocket-like space inside the diaper.

[0008] When putting on and taking off such shorts-type disposable diapers, the toes or heels may be caught in the pocket-shaped space, which hinders wearing

[0009] And, in the case of the above-mentioned Patent Document 2, the diaper itself and the absorber of the diaper are fitted to the body by bending the ela
