  • Patent number: 11266547
    Abstract: A liquid permeable surface sheet (3) includes an upper layer non-woven fabric (20) which is provided at the skin side, and which is hydrophilic, and a lower layer non-woven fabric (21) which is provided at the non-skin side, and which is water repellent. Multiple apertures (22) are formed which penetrate the upper layer non-woven fabric and the lower layer non-woven fabric. Accordingly, body fluid transfers smoothly through the apertures to an absorbent body. The upper layer non-woven fabric at the skin side is made to be hydrophilic such that body fluid readily permeates therethrough. The lower layer non-woven fabric at the non-skin side is made to be water repellent such that the body fluid which has passed through is not readily absorbed again. Accordingly, the backflow amount of body fluid can be reduced.

    Abstract: An absorbent article includes a pair of ears secured to and extending transversely outward from opposite sides of a back portion of the article. Each of the ears is stretchable in at least a transverse direction of the article from a relaxed position to an extended position. A waistband includes a waist elastic disposed in at least the back portion. The waist elastic has an in product load loss of less than 60 percent according to a four-hour hold stress relaxation test. A fastening system has a primary fastening system and a secondary fastening system. In a wear configuration of the absorbent article, the secondary fastening system secures each of the ears of the pair of ears in the extended position.

  • Patent number: 9023007
    Abstract: A wearing article configured to smooth out wrinkles that tend to be created in front and rear waist regions. A diaper includes front and rear waist members connected to an intermediary crotch. The front and rear waist members extend from waist ends toward the side of a crotch region and respectively include first regions overlapping front and rear end flaps of the absorbent structure and second regions adjacent the respective first regions. In the front and rear waist members, the first regions and the second regions are provided with first and second waist elastic members sandwiched between the respective top- and backsheets. The respective second regions are formed with inelastic zones overlapping the core and elastic regions lying on both sides of the inelastic regions in the transverse direction. The tightening force of the first regions are lower than the tightening force of the respective second regions.

  • Patent number: 9023006
    Abstract: The present invention aims to provide a wearing article adapted to prevent unintentional displacement of a crotch region relative to front and rear waist regions by elastics attached to the crotch region. A diaper includes front and rear waist members, a crotch member by the intermediary of which the front and rear waist members are connected with each other. The rear waist member is formed with a waist fit section and an appendix section. Of the crotch member, front and rear ends including front and rear end flaps are bonded to the front and rear waist members, respectively, to form front and rear bonded regions. Both side flaps are provided on respective inner surfaces thereof with gasket elastics attached thereto. Each of the gasket elastic overlaps at one end with a part of the front waist elastic and overlaps at the other end with a part of the appendix section elastic. Furthermore, the one end overlaps with the front bonded region and the other end overlaps with the rear bonded regions.
