Abstract
A disposable wearing article has first and second barrier flaps on first and second side flaps, respectively. A crotch region is formed with first and second folding guide lines diverging from the vicinity of proximal edges of the first and second barrier flaps toward side edges of the first and second side flaps, respectively. First and second sections of the crotch region are tucked inwardly along the first and second folding guide lines in a transverse direction of the article, respectively, but distal portions of the first and second barrier flaps are not tucked inwardly of the article.
Claims10
A pull-on disposable wearing article, comprising:
- a front waist region;
- a rear waist region opposed to said front waist region;
- a crotch region extending in a longitudinal direction of said article between said waist regions;
- a waist-hole;
- a pair of leg-holes;
- an absorbing zone extending between said front and rear waist regions;
- a pair of end flaps extending in a transverse direction of said article and outside longitudinally opposite ends of said absorbing zone;
- first and second side flaps extending in the longitudinal direction and outside transversely opposite side edges of said absorbing zone, respectively;
- first and second barrier flaps extending in the longitudinal direction on said first and second side flaps, respectively, each of said first and second barrier flaps comprising
- a proximal portion extending in the longitudinal direction,
- longitudinally opposite ends lying on said end flaps and collapsed inwardly in the transverse direction, and
- a distal portion being elastically stretchable and contractible and biased to extend upward from said proximal portion;
- a pair of first folding guide lines extending, in a longitudinally middle zone of said crotch region, from a vicinity of the proximal portion of said first barrier flap toward a side edge of said first side flap and towards said front and rear waist regions, respectively;
- a pair of second folding guide lines extending, in a longitudinally middle zone of said crotch region, from a vicinity of the proximal portion of said second barrier flap toward a side edge of said second side flap and towards said front and rear waist regions, respectively;
- and
- third and fourth barrier flaps extending in the longitudinal direction outside said first and second barrier flaps, respectively, each of said third and fourth barrier flaps comprising
- a proximal portion extending in the longitudinal direction,
- longitudinally opposite ends lying on said end flaps and collapsed outwardly in the transverse direction, and
- a distal portion being elastically stretchable and contractible and biased to extend upwardly from said proximal portion;
- wherein
- a first section of said crotch region defined by said first folding guide lines and the side edge of said first side flap is folded along said first folding guide lines and tucked inwardly of said article, and a second section of said crotch region defined by said second folding guide lines and the side edge of said second side flap is folded along said second folding guide lines and tucked inwardly of said article;
- the distal portions of said first and second barrier flaps are not folded and tucked inwardly together with said first and second sections, whereas the distal portions of said third and fourth barrier flaps are folded and tucked inwardly together with said first and second sections.

A pull-on disposable wearing article having longitudinal and transverse directions, said article comprising:
- a liquid impervious cover sheet defining front and rear regions and a crotch region extending in the longitudinal direction between said front and rear regions;
- a pad comprising a liquid-pervious topsheet, a liquid-impervious backsheet attached to an upper side of said cover sheet, and a liquid-absorbent core interposed between said topsheet and backsheet;
- and
- first and second barrier flaps each having a proximal portion bonded to the topsheet of said pad, a distal portion, and an elastic member attached to said distal portion to bias said distal portion to extend upward from said topsheet of said pad and outwardly in the transverse direction away from said pad;
- wherein transversely opposite lateral portions of the crotch region are folded along a pair of V-shaped folding lines and tucked inwardly of the article;
- wherein the article further comprises third and fourth barrier flaps each having a proximal portion bonded to the topsheet of said pad, a distal portion, and an elastic member attached to said distal portion to bias said distal portion to extend upward from said topsheet of said pad and inwardly of said pad in the transverse direction;
- and
- wherein the distal portions of said third and fourth barrier flaps are not folded and tucked together with the transversely opposite lateral portions of the crotch region, whereas the distal portions of said first and second barrier flaps are folded and tucked together with the transversely opposite lateral portions of the crotch region.
