Abstract
Disposable garments of pants type having a waist-opening with a first elastic member, a pair of leg-openings with second elastic members and a pair of cuff members with third elastic members which are inwardly spaced from said second elastic members, respectively and thereby said leg-openings are provided with double elastically stretchable seal structures.
Claims5
Disposable garments of pants type having a waist-opening provided with a first elastic member and a pair of leg-openings provided with ring-like second elastic members, wherein there are provided a pair of cuff members inwardly spaced from said second elastic members, respectively, and these cuff members are adapted to rise against the user's skin under a contractile force of third elastic members contained in these cuff members, respectively, wherein, with the garments unfolded and respective opposed side edges of front and rear bodies thereof being still not bonded together, said second elastic members for the respective leg-openings are positioned to be curved inward while said third elastic members for the cuff members are positioned substantially in parallel to the longitudinal axis of the garments so that, once put on the user's body, elastically stretchable lines defined by said second elastic members partially intersect elastically stretchable lines defined by said third elastic members so as to bias said cuff members against the user's skin.
Disposable pants that contain a single waist opening (2) and two leg openings (3) and an absorbent core (14) sandwiched between a water-permeable inner sheet (12) and a water-impermeable outer sheet (13), the improvement which comprises
- (a) a first elastic member (4) mounted in said waist opening (2) which applies a contractile force to said waist opening (2),
- (b) ring-like second elastic members (5) provided in each leg opening (3),
- (c) spaced apart cuff members (6) mounted on said inner sheet (12) at least partially inwardly from said second elastic members (5), said cuff members (6) extending along lines that are substantially parallel to each other and substantially parallel to the longitudinal axis of the pants, and said cuff members (6) are formed from a moisture-permeable but water-impermeable non-woven fabric, and
- (d) a third elastic member (7) mounted within each cuff member (6) so as to exert a contractile force that causes each cuff member (6) to rise against the leg of a person wearing the pants,
- a portion of the elastically stretchable lines defined by said second elastic members (5) extend toward the longitudinal axis of the pants and partially intersect the elastically stretchable lines defined by said third elastic members (7) so as to bias said cuff members (6) against the user's skin.
