  • Patent number: 11529265
    Abstract: A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

  • Patent number: 11517484
    Abstract: The present invention is intended to provide an absorbent article that is excellent in anti-odor effect at the time of disposal. A pants-type disposable diaper includes an anti-odor tape that has a first gas barrier layer coupled to the pants-type disposable diaper and a second gas barrier layer that is stuck in a separable manner to either front or back surface of the first gas barrier layer via an adhesive agent containing an anti-odor agent. The anti-odor tape takes an anti-odor measure by separating the second gas barrier layer from the first gas barrier layer to expose the adhesive agent to the outside at the time of disposal of the pants-type disposable diaper.
