  • Publication number: 20120296294
    Abstract: The present invention to provide an absorbent structure adapted to prevent the liquid-absorbent materials from falling off the wrapping sheets. An aggregate of liquid-absorbent materials in an absorbent structure has an inner surface covered with a first wrapping sheet and an outer surface and lateral surfaces covered with a second wrapping sheet. The first wrapping sheet and the second wrapping sheet respectively have first extended portions lying outboard of the lateral surfaces and second extended portions wherein the first extended portions and the second extended portions are put flat and bonded together to form laminated regions. The laminated regions cover the lateral surfaces of the aggregate and part of the outer surface which, in turn, covers these lateral surfaces and the outer surface.

  • Publication number: 20120289922
    Abstract: The present invention provides a disposable pants-type wearing article free from possibility that upper regions of the leg-openings' peripheral edges might be formed with frills even when the belt-like leg elastic members contract along the peripheral edges of the respective leg-openings. Belt-like leg elastic members in a disposable pants-type diaper each has inner and outer surfaces at least one of which is bonded to sheet-like members included in put flat and joined together regions and a crotch region of the diaper. The belt-like leg elastic members extend from the respective put flat and joined regions along leg-openings' peripheral edges. Over ranges in which the belt-like leg elastic members extend along the respective peripheral edges the sheet-like members also extend along the peripheral edges.

    Abstract: The present invention provides a disposable pants-type wearing article using belt-like leg elastic member. Respective opposite side edges of front and rear waist regions of a disposable pants-type wearing article are fusion-bonded together to define put flat and joined together regions. Belt-like leg elastic members respectively have front side upper ends lying in the front waist region and included by the put flat and joined together regions and rear side upper ends lying in the rear waist region and included by the put flat and joined together regions. In the put flat and joined together regions, lower edges of the upper ends and lower edges of the rear side upper ends are displaced one from another in such a manner that the one pair of the lower edges lie below the other pair of the lower edges. The one pair of the lower edges are fusion-bonded to at least one of a sheet-like member and a sheet-like member covering the other pair of the lower edges at a level lower than the other pair of the lower edges.

  • Publication number: 20120253307
    Abstract: A pant-type disposable wearing article includes at least one waist region of front and rear waist regions, which includes an inner sheet lying on the skin-facing side and an outer sheet lying on the non-skin-facing side. The inner sheet has a contractile force higher than that of the outer sheet at least in the transverse direction X. Opposite lateral sections of the inner sheet and opposite lateral sections of the outer sheet are permanently bonded together and extend outward in the transverse direction X from arrays of side seam spots to form front flaps and rear flaps defining protruding rims. The front flaps and the rear flaps are curled inwardly. This article is improved so that opposite side edges do not irritate a wearer's skin even if the wearer's skin comes in contact with these side edges and, in addition, good appearance from a lateral view is assured.

  • Publication number: 20120253306
    Abstract: The present invention aims to provide a disposable wearing article improved so that front and rear waist regions may assure desired fitness without adversely affecting an absorption capacity of a bodily fluid-absorbent core assembly. At least one of front and rear waist regions includes an inner sheet lying on a skin-facing side and having stretch properties and an outer sheet lying on a non-skin-facing side and having a low elastic contractile force. In a section of this one waist region occupied by a liquid-absorbent core assembly including a bodily fluid-absorbent core, the inner sheet is partially cut to define a perforated region. Adhesive used to bond the liquid-absorbent core assembly to the inner sheet and adhesive used to bond the inner sheet to the outer sheet are put in contact with and joined to each other through openings developed by partially cutting the inner sheet.

  • Patent number: 8183429
    Abstract: A composite sheet which has a low basis weight, can be prevented from breaking during the production of an absorbent article or in use, and is good to the touch. The composite sheet is a sheet formed by bonding a stretch nonwoven fabric to a nonstretch nonwoven fabric with an adhesive. The stretch nonwoven fabric is bonded in a stretched state to the nonstretch sheet. The stretch nonwoven fabric has, on each side, strip-form sparse regions and strip-form dense regions alternately formed. The sparse regions and dense regions on one side are alternately formed in a second direction so that the dense regions on this side do not overlie the dense regions on the other side. The composite sheet has a maximum breaking strength of 20 N/50 mm or higher.
