Definitions
- the present disclosure relates to a disposable wearing article and more specifically to a wearing article such as a disposable diaper having elastic regions defined by elastic bands.
- elastic members made of, for example, urethane foam (Spandex), each having the width in a range of 10 to 45mm, are bonded to the respective peripheries of the waist-opening and the leg-openings to form these peripheries with the elastic regions including gathers.
- the elastic members extend straight in the transverse direction of the pants along the periphery of the waist-opening. However, along the periphery of each leg-opening, some of the elastic members extend straight in the transverse direction of the pants while other elastic members extend straight in the vertical direction of the pants.
- leg-surrounding gasket-cuffs are formed with curved elastic regions. These elastic regions are obtained by bonding belt-like elastic sheet members evenly stretched in the length direction to the respective gasket-cuffs so that the regions along which the elastic sheet members are bonded to the gasket-cuffs may describe curved lines.
- the elastic sheet members are integrated with the gasket-cuffs to define the elastic regions around the wearer's legs. Polyurethane foam (Spandex), polyethylene foam or the like are used as material for the elastic sheet members.
- the preferred belt-like elastic members are made of urethane foam (Spandex).
- the belt-like elastic members made of such material are elastically deformable in a recoverable manner as these elastic members are compressed in the thickness direction and whereby render the peripheries of the waist- and/or leg-openings comprising such elastic members soft and comfortably textured.
- the known wearing articles also use, in addition to urethane foam, plastic film, thin layered sheet of natural rubber, synthetic rubber or the like, and melt blown non-woven fabric as the material for the belt-like elastic members.
- an elastic member made of plastic film, thin layered sheet of rubber or non-woven fabric it is often difficult for an elastic member made of plastic film, thin layered sheet of rubber or non-woven fabric to be as elastically recoverable as an elastic member made of polyurethane foam. Consequently, it is difficult for elastic members made of such plastic films, thin layered sheets of rubber or non-woven fabrics to render the peripheries of the waist- and/or leg-openings soft and comfortably textured.
- One or more embodiments of the invention relates to a disposable wearing article having front and rear waist regions, a crotch region between the front and rear waist regions, a waist-opening defined by the front and rear waist-regions, and leg-openings defined by the front and rear waist regions and the crotch region.
- a periphery of at least one of the waist-opening and the leg-openings has an elastic region including an elastic band of a first fibrous sheet which is elastically contractible in a circumferential direction of the at least one of the waist-opening and the leg-openings.
- the elastic band includes a plurality of first gathers which extend in a length direction of the elastic band along the circumferential direction and undulate in a width direction of the elastic band.
- the front and rear waist regions include an inner sheet and an outer sheet, at least one of both surfaces of the elastic band is bonded to at least one of the inner and outer sheets so as to form second gathers which extend in a direction crossing the first gathers are formed, when the elastic band contracts.

- Measurements of the height of the crests and the thickness of the fibrous non-woven fabric in this disclosure are carried out by subjecting the test pieces to a compression force of 0.5g/cm 2 using Automatic Compression Tester KES-FB3-AUTO-A (manufactured by KATO TECH CO. LTD. in Japan) as measuring means.
