The absorbent includes first front and rear elasticized regions outside of opposite lateral regions as viewed in a transverse direction of the separate sheet. Each of these first front and rear elasticized regions is paired and spaced apart from each other in the transverse direction and between respective pairs of first front and rear elasticized regions. Front and rear non-elasticized regions are free from any influence by the contractile force of the front and rear waist elastic members. The sub-regions of the front and rear waist regions unoccupied by a liquid-absorbent structure extend in the transverse direction between respective pairs of opposite side edges. | 04-28-2011 |

First joint zones continuously extend in a longitudinal direction Y and substantially overlap the absorbent structure as viewed in a thickness direction. Leak-barrier cuffs provided on the side of the separate sheet are joined to the inner sheet via second joint zones lying outside the separate sheet as viewed in a transverse direction X, joined to the separate sheet via third joint zones, and joined to the separate sheet via fourth joint zones. | 07-28-2011 |
20120016334 | DISPOSABLE DIAPER - A disposable diaper using elastic sheet materials so that a contact surface pressure may be locally enhanced and thereby the diaper may be prevented from being noticeably displaced on the wearer's body during used thereof is provided. Of first and second waist regions at least the first waist region is contractible. The first waist region includes waist auxiliary elastic sheets extending in a direction of a transverse axis between opposite side edges of the first waist region and leg auxiliary elastic sheets extending along front peripheral edges of leg-openings. The waist auxiliary elastic sheets and the leg auxiliary elastic sheets overlap one another in areas of the opposite side edges of the first waist region adjacent to the leg-openings respectively.

20120022482 | ABSORBENT ARTICLE - An absorbent article is provided with a waist-cuff to prevent body waste from leaking beyond a waist-opening. An elastic sheet is used for the waist-cuff to be held in contact with the wearer's skin even if the wearer moves. The waist-cuff and a chassis may be joined to each other so as to be separated from each other in the vicinity of an absorbent structure to assure that fitness of the waist-cuff to the wearer's skin is not significantly affected by movement of the wearer and, at the same time, to assure that leg-cuffs can rise without being collapsed by the waist-cuff. The ends of the leg-cuffs are interleaved between the waist-cuff and the chassis to prevent body waste from leaking through a clearance which would otherwise be defined between the leg-cuffs and the waist-cuff. | 01-26-2012 |
