  • Patent number: 11389343
    Abstract: An absorber, a liquid impervious sheet covering a back surface side of the absorber and having air permeability, and a cover nonwoven fabric covering a back surface side of the liquid impervious sheet are provided. The cover nonwoven fabric has a large number of holes penetrating the front surface and back surface at intervals in a region overlapping with the liquid impervious sheet. Edge portions of the holes bend-up toward a front surface side. In a region having the holes in the cover nonwoven fabric, rows of the holes, which are aligned in the front-back direction at intervals in the front-back direction narrower than the dimension in the front-back direction of each of the holes, are repeatedly formed at predetermined intervals in the width direction, and the interval of the adjacent two holes in the width direction is wider than the dimension in the front back-direction of the hole.

  • Patent number: 10398609
    Abstract: Provided is a method for manufacturing a stretchable elastic member excellent in appearance and reduced in manufacturing cost by applying a first adhesive to an inner surface of a sheet at one side at predetermined intervals, applying a second adhesive to elongated resilient and elastic members at predetermined intervals, forming first application regions in which the first adhesive is applied and first non-application regions between the first application regions and the adjacent first application regions, forming second application regions in which the second adhesive is applied over a large number of the first application regions and second non-application regions between the second application regions and the adjacent second application regions, fixedly installing, on an inner surface of the sheet at the one side, the elongated resilient and elastic members and a sheet at the other side at the outer side of the elongated resilient and elastic members, and cutting the elongated resilient and elastic member

  • Patent number: 10092457
    Abstract: In an underpants-type disposable diaper including a waist edge portion in which pleats extend straight and which has excellent fit, the inner layer and the outer layer at the waist edge portion of an outer body are joined by an adhesive arranged intermittently or a welding process performed intermittently in the width direction and continuously in a direction crossing the width direction, thereby forming sheet joined sections, waist edge portion resilient and elastic members are sandwiched between the inner layer and the outer layer and fixed to at least one of the inner layer and the outer layer at positions intersecting with the sheet joined sections, and the diaper includes an area not being joined and not having resilient and elastic member at an end portion of the outer body on the waist opening side in the waist edge portion, the area not having sheet joined sections nor the waist edge portion resilient and elastic members, and a vertical range being wider than spacing between the waist edge portion res
