Embodiment Construction

[0019] The disposable diaper of the present invention will be described in detail with reference to the drawings, as follows.

[0020] figure 1 It is a partial cross-sectional perspective view of an underpants-type disposable diaper 1 as an example of a disposable diaper, and the front-rear direction, the lateral direction, and the height direction of the diaper 1 are indicated by mutually orthogonal double-headed arrows A, B, and C. The diaper 1 is symmetrical with respect to the center line P that bisects the dimension of the horizontal direction B, and has a crotch panel 6 for forming a crotch region 2, and a front panel for forming a front waist region 3 located in front of the crotch region 2. 7. The rear panel 8 for forming the rear waist region 4 located behind the crotch region 2, the front and rear panels 7, 8 are overlapped on the side of the waist in a folded palm shape and are joined at intervals in the vertical direction C The regions 20 are welded to each other....

Abstract

A disposable diaper wherein the gap occurring between the wearer's skin and leakage preventive cuffs formed on both sides of a crotch region is reduced. The disposable diaper (1) has a pair of cuffs (323, 33) extending along the back and forth direction A on both sides of a crotch region respectively and capable of stretching and contracting. one (32) of the pair of cuffs has a first elastic component (47) at the outside rim part. the other (33) thereof has a base rim part fixed on the inner surface of the cuff (32) and a second elastic component (49) mounted at the free rim part. A third elastic component (60) is mounted on at least of the pair of cuffs (32, 33) adjacent to the part with the base rim part (44).

Description

technical field [0001] The present invention relates to a disposable diaper. Background technique [0002] Disposable diapers are conventionally or even well known, each having a pair of leak-proof cuffs extending parallel to each other in the front-rear direction on both sides of the crotch region. [0003] For example, the underpants type diaper described in Japanese Unexamined Patent Application Publication No. 2002-102278 (Patent Document 1) has thigh openings on both sides of the crotch region in which thigh elastic members are ring-shaped, and the thigh openings are closer to the diaper than the thigh openings. A pair of leak-proof cuffs extending in the front-rear direction at the inside position. The cuffs respectively have elastic edge portions capable of elastic expansion and contraction. An elastic member extending linearly is attached to the elastic edge. When wearing the diaper, the edge of the thigh opening is closely attached to the entire thigh by the acti...
