Patents by Inventor Kenichi Uchimoto

Kenichi Uchimoto has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8686217
    Abstract: An absorbent product has a top sheet, an absorbent core and a back sheet. The absorbent core includes 40% by weight or more of high absorbent resin powder and it is possible to slim down the absorbent core while keeping a sufficient amount of absorption to thereby achieve slimming down of the absorbent product. A top sheet lower part contacting the high absorbent resin powder in the absorbent core includes hydrophilic fibers having water retention characteristics, and moisture is temporarily retained in the top sheet lower part before reaching the absorbent core and rapidly disperses in a range facing the absorbent core of the top sheet lower part. As a result, it is possible to reliably absorb the moisture of excrement in the absorbent core and to simplify a structure of the absorbent product.

  • Publication number: 20080319408
    Abstract: An absorbent product has a top sheet (21), an absorbent core (22) and a back sheet. The absorbent core (22) includes 40% by weight or more of high absorbent resin powder (223) and it is possible to slim down the absorbent core (22) while keeping a sufficient amount of absorption to thereby achieve slimming down of the absorbent product. A top sheet lower part (212) contacting the high absorbent resin powder (223) in the absorbent core (22) includes hydrophilic fibers (2122) having water retention characteristics, and moisture is temporarily retained in the top sheet lower part (212) before reaching the absorbent core (22) and rapidly disperses in a range facing the absorbent core (22) of the top sheet lower part (212). As a result, it is possible to reliably absorb the moisture of excrement in the absorbent core (22) and to simplify a structure of the absorbent product.

  • Patent number: 6972011
    Abstract: In an ultra-thin absorbent sheet member 1a in which an absorbent polymer powder 3 is adhered to one surface of a first nonwoven fabric 2 by a hotmelt adhesive such that absorbent polymer powder present areas 2c and absorbent polymer powder absent areas 2a, 2b exist; the absorbent polymer powder absent areas are present at opposite widthwise ends (2a) of the ultra-thin absorbent sheet member and at least one position (2b) between the opposite ends; the absorbent polymer powder 3 is bonded to the first nonwoven fabric 2 by first hotmelt adhesive layers S1 formed on an upper side of the first nonwoven fabric 2 and on a lower side of the absorbent polymer powder 3 and a second hotmelt adhesive layer S2 formed to cover upper sides of the absorbent polymer powder present areas 2c and the absorbent polymer powder absent areas 2a, 2b; and the first hotmelt adhesive layer S1 and the second hotmelt adhesive layer S2 are both made of an aggregate of linear hotmelt adhesive pieces.

  • Patent number: 6569137
    Abstract: An absorbent incontinence pad is provided with a liquid impervious air permeable back sheet and an absorbent unit partly covered by the back sheet, wherein the absorbent unit has a non-woven fabric substrate, an absorbent zone formed by a plurality of highly absorbent layers extending in the form of bands on the surface of the non-woven fabric substrate and an air permeable zone where no such highly absorbent layer exists, which has sufficiently adequate properties to meet incontinence requirements and provides a comfortable feeling during use.

  • Patent number: 6369291
    Abstract: Disposable underpants 1 according to the invention has an improved sealability at the crotch of user by providing a fitting elastic member 55 and has an absorbent core 7 having an improved shape retention by providing a first nonwoven fabric 73 as an intermediate layer inside the absorbent core 7 and adhering it to the upper and lower layers thereof. Since the absorbent core needs not be heated, inexpensive disposable underpants can be produced. Further, according to an inventive production method, a step of adhering elastic members to an outer sheet 2 and a step of producing inner absorbent members 6 are separately performed, and no heating treatment is performed in the absorbent core production step. Accordingly, the disposable underpants can be produced at a remarkably higher speed.
