  • Publication number: 20050133395
    Abstract: A diaper package is composed of a plurality of disposable diapers and a flexible packing bag forming top and bottom walls, and front, rear and laterally opposed walls printed with display elements. These diapers are arranged between the laterally opposed walls to form a row extending between these laterally opposed walls in such a manner that respective crotch regions of these diapers face the rear wall while respective waist-surrounding end portions of these diapers face the front wall. A radius of curvature of the corners is longer than a radius of curvature of the corners so that a range in which the package can be visually recognized from the side of the front wall is larger than a range in which the package can be visually recognized from the side of the rear wall.

  • Publication number: 20050107761
    Abstract: Here is disclosed a disposable wearing article in the article, an area of a rear waist region in which a core is present is divided into a first area and a second area. The second area is formed in its transversely middle zone with a through-hole extending through the core. A transverse flexural stiffness of the core lying in the second area is lower than a transverse flexural stiffness of the core lying in crotch region and the first area and proximal portions of leak-barrier sheets and longitudinal ends of elastic members are laid on the first area. The first area lies above the crotch region in a thickness direction of the article and the second area forms a barrier and a pocket.

  • Patent number: 6840925
    Abstract: A throwaway wearing article for disposal of bodily discharges improved so that a cylindrical guide for bodily discharge can be brought in close contact with a zone surrounding the anus without use of an adhesive. A flat bag-like receptacle is formed on its upper sheet with an inlet means having the cylindrical guide adapted to guide bodily discharge such as loose passage into a receptacle. An elastically stretchable supporting member extending under extension between front and rear sections of the receptacle is operatively associated with a peripheral edge of the upper end of the cylindrical guide.

  • Patent number: 6780173
    Abstract: A disposable undergarment includes a pair of elastically stretchable first wings extending outward from transversely opposite side edge portions of a rear waist region, proximal side edge portions of the respective first wings are contiguous to transversely opposite side edge portions of a crotch region. The undergarment further includes a pair of elastically stretchable second wings placed upon the first wings and extending outward from the transversely opposite side edge portions of the rear waist region, proximal side edge portions are not contiguous to the transversely opposite side edge portions of the crotch region. A stretch stress generated in the first wings as the front and rear waist regions are connected to each other is exerted upon the undergarment in a waist-surrounding direction as well as in a thigh-surrounding direction but a stretch stress generated at the same time is exerted upon the article only in the waist-surrounding direction.
