Problems solved by technology

That is, in the outer body of the conventional underpants-type disposable diaper, since the male genitalia facing part is not provided with an elastic elastic member, or even if an elastic elastic member is provided, it is arranged so that the shrinkage force acts uniformly in the width direction. Therefore, in the case of the former, the opposite part of the male genitalia becomes loose, which is easy to affect the shape of the clothes, and in the case of the latter, it will cause the male genitalia to be oppressed

Embodiment Construction

[0047] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In addition, the dotted part in the cross-sectional view represents joining means such as a hot-melt adhesive.

[0048] Figure 1 to Figure 7A pant type disposable diaper is shown. This pants-type disposable diaper (hereinafter, simply referred to as a diaper.) has: an integral outer body 20 that constitutes a front body part F and a back body part B; The inner body 10 is integrated, and the absorber 13 is interposed between the liquid-permeable top sheet 11 arrange|positioned at the front side, and the liquid-impermeable sheet 12 arrange|positioned at the back side. During manufacture, the back of the inner body 10 is bonded by bonding means such as hot-melt adhesive ( Figure 7 After the pattern part 10B) of the outer body 20 is placed on the inner surface of the outer body 20, the inner body 10 and the outer body 20 are folded at the boundary between the...

Abstract

The present invention addresses the problem of enhancing fit properties with respect to male genitalia. The above problem is solved by a configuration whereby at least a male-genitalia-facing portion(100) and portions on both sides thereof in a width direction (WD) thereof in an exterior body (20) of a front part (F) have: an elastic film stretch structure (20X) in which an elastic film (30) is layered between a first sheet layer (20A) and a second sheet layer (20B), and the first sheet layer (20A) and the second sheet layer (20B) are directly or indirectly joined by numerous sheet joining parts (40) arranged at an interval; and a variation region (90) in which the surface area of the joining parts (40) decreases in stages or continuously from a center part of the male-genitalia-facing portion (100) in the width direction (WD) thereof toward both sides of the male-genitalia-facing portion (100) in the width direction (WD) thereof; the portion of the variation region (90) other than atleast a portion (91) where the surface area of the joining parts (40) is greatest being extensible in the width direction (WD) and contracted in the width direction (WD) by contraction of the elasticfilm (30) in a natural length state.

Description

technical field [0001] The present invention relates to a pants-type disposable diaper excellent in fit to male genitalia. Background technique [0002] Underpants-type disposable diapers generally include: an outer body that separately or integrally constitutes a front body part and a rear body part; On the surface, the side seals are formed by joining the side edges of the outer body of the front body part and the outer body of the back body part together to form a waist opening and a pair of left and right leg openings. [0003] In general, the exterior body has a waist region and a middle region, wherein the waist region is determined to have a front-rear direction range of the side seal (the front-rear direction range from the waist opening to the upper end of the leg opening), and the middle region is defined as Determine the range in the front-rear direction of the portion forming the leg opening, the middle region has a cover region positioned at the side of the inn...
