  • Patent number: 12023232
    Abstract: An absorbent sheet is capable of increasing the absorption capacity in a desired region of an applied wearing article, for example, a crotch portion of a disposable diaper. An absorbent polymer is provided inside a first space region where the periphery is partitioned between a first sheet and a second sheet, and in the first space region, a resistance portion is formed by bonding the first sheet and the second sheet, and the resistance portion is to increase the resistance to gravity movement of the absorbing polymer in the first space region.

  • Publication number: 20220387231
    Abstract: [Problem to be solved] To reduce uncomfortable feeling during wearing, and to prevent leakage from a side portion. [Solution] An absorber 4, and side sheets 7 disposed on both side portions in a longitudinal direction of a skin-contact surface side over an entire length in the longitudinal direction are provided. The side sheets 7 do not include an elastically stretchable member. There are provided a non-adhesive portion 10, in which a center portion in the width direction of the side sheets 7 is not bonded to the absorber 4 side, in a longitudinal section including a region corresponding to a body fluid discharge portion H of a wearer, and adhesive portions 11 and 12 in which side sheets 7 are bonded to the absorber 4 at an outer side in the width direction and at both end sides in the longitudinal direction of the non-adhesive portion 10.

  • Patent number: 11399990
    Abstract: To provide an absorbent pad, the absorbent pad being formed of an inner absorbent pad which is positioned on the body-side and an outer absorbent pad positioned on the non-body side, wherein when the inner absorbent pad absorbs liquid excretions and swells, openings are provided at the side which is indented furthest towards the non-body side, improving the passage of liquid, and improving the dispersion of sites facing the openings in the outside absorbent pad, preventing leakage of liquid excretions to the exterior.

  • Patent number: 11389344
    Abstract: Disclosed is an absorbent pad which efficiently diffuses excretory fluid and gives no sense of discomfort to a wearer even after excretion. A front sheet and a rear sheet are joined to each other at a plurality of first junctions and a plurality of second junctions, and when viewed in plan, the first junctions extending in a longitudinal direction are arranged at predetermined intervals in a width direction, and second junctions extending in the width direction are arranged at predetermined intervals in the longitudinal direction. A plurality of cells, each of which is defined by an adjacent pair of the first junctions and an adjacent pair of the second junctions, is formed between the front sheet and the rear sheet spaced apart from each other. An opening extending in the longitudinal direction is formed in at least one of the first junctions.

  • Patent number: 11291596
    Abstract: Provided is an absorbent pad which prevents leakage of excess liquid excrement to the exterior. An absorbent pad sheet forms an absorbent pad from a liquid-permeable front sheet and a liquid permeable rear sheet, and absorbent polymer particles which absorb liquid excrement and which are provided between the front sheet and the rear sheet. The width in the width direction formed between both side parts folded to the inside is formed as 10-50% of the width of the absorbent pad in the width direction, and some of the absorbent polymer particles at the place at which folding to the inside occurs are made to penetrate the front sheet at the place at which folding to the inside occurs.

  • Publication number: 20210220188
    Abstract: An absorbent article includes a top sheet, a liquid impermeable back sheet, and an absorbent body interposed between the top sheet and the back sheet. Welded portions are formed on at least a part of the top sheet. The welded portions constitute a plurality of units, and each of the units includes rod portions that are arranged radially in planar view. The distance between adjacent units is greater than the diameter of a smallest virtual circle inscribed in the rod portions included in each of the units.

  • Publication number: 20210169707
    Abstract: A core press depressed toward a back-side sheet is formed on at least a surface of an absorber facing an upper-side sheet such that the thickness of the absorber is reduced in the thickness direction, right and left compressed grooves are formed along the longitudinal direction of a sanitary napkin on at least the sides of an area corresponding to a body fluid discharge part of a wearer, and a high absorption part having a greater absorption capacity per unit area than other parts is formed at least between the right and left compressed grooves of the absorber.

  • Publication number: 20200214908
    Abstract: An absorbent article has a front surface side sheet and a back surface side sheet disposed on a back surface side of the front surface side sheet. A large number of cells are formed by bonding the front surface side sheet and the back surface side sheet. A particulate material containing super absorbent polymer particles is accommodated in the cell to form an absorber. At least a part of the particulate material containing the super absorbent polymer particles is not fixed to at least one of the front surface side sheet and the back surface side sheet. In at least one of the front surface side sheet and the back surface side sheet, sites other than the sites where the sheets are bonded each other are shrunk into a pleat shape.
