Embodiment Construction

[0065] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The dotted part in the cross-sectional view indicates the adhesive used as the joining means for joining the constituent parts located on the front side and the back side. Formed by coating, curtain coating, sumit coating or spiral coating, or pattern coating (transfer of hot-melt adhesive by relief method), or elastic parts The fixing portion is formed by applying the adhesive to the outer peripheral surface of the elastic member with a coating gun, glue coating, or the like instead of the adhesive or together with the adhesive. As the hot-melt adhesive, there are, for example, EVA-based, adhesive rubber-based (elastic), olefin-based, and polyester-polyamide-based adhesives, which can be used without particular limitation. As the joining means for joining the constituent members, means by material welding such as heat sealing or ultrasonic sealing may be used....

Abstract

The invention provides an underpants-type disposable diaper to prevent deterioration of appearance due to a conspicuous corner of the leg-opening side of the side edge of a buttocks cover portion in atwo-part outer-shell-type underpants-type disposable diaper. The abovementioned problem is solved by an underpants-type disposable diaper in which a front outer shell 12F and a rear outer shell 12B are provided separately and the front outer shell 12F and rear outer shell 12B are separated in the longitudinal direction LD at the center of the longitudinal direction LD, wherein the rear outer shell 12B has a buttocks cover portion C extending more toward the longitudinal-direction center than does a side seal portion 12A, and the longitudinal-direction dimension of the side edge of the buttocks cover portion C is 0.9-1.1 times the width-direction dimension W3 from the side edge of the rear outer shell 12B to the width-direction-center-side side edge of the side seal portion 12A.

Description

technical field [0001] The present invention relates to a pants-type disposable diaper. Background technique [0002] Generally, the underpants-type disposable diaper includes: an outer body that separately or integrally constitutes a front body part and a back body part; Body, both side edges of the outer body of the front body part and both side edges of the outer body of the back body part are joined together to form side seals, thereby forming a waist opening and a pair of left and right leg openings. [0003] In such a pants-type disposable diaper, in order to improve the fit to the body, the outer body is formed into a laminated structure having a plurality of sheets, and various elastic members are attached between the sheets in an extended state. , wherein the following structure has relatively high fit to the body: in the waist region determined as the front-rear direction range corresponding to the side seal portion, or in the middle region between the front and r...
