  • Patent number: 10602715
    Abstract: An absorbent sheet includes a liquid-permeable topsheet, a liquid-impermeable backsheet and a liquid-absorbent structure interposed between the top- and backsheets. In the sheet, the topsheet faces itself and is bonded to itself by a joining means extending in a transverse direction so as to define a fold edge extending in a transverse direction. The absorbent structure includes a first absorbent section extending between a front end edge and the fold edge, a second absorbent section extending between the fold edge and the joining means and a third absorbent section extending between the joining means and a rear end edge. Outboard of the third absorbent section of the sheet in the longitudinal direction, a non-absorbent region in which the absorbent structure is not present is formed. A portion of the backsheet of the sheet within the non-absorbent region is attached to a wall by attachments.

  • Patent number: 10383309
    Abstract: An absorbent sheet for pets that is highly effective in concealing pet excrement. The absorbent sheet includes: a liquid-permeable front-surface sheet; a liquid-impermeable back-surface sheet; an absorbent body that is provided between the front-surface sheet and the back-surface sheet, and that absorbs liquid that has permeated through the front-surface sheet; an intermediate sheet that is arranged between the front-surface sheet and the absorbent body; and a color arrangement region that forms a color arrangement pattern together with at least one of the front-surface sheet, the back-surface sheet, and the absorbent body. The front-surface sheet is formed so as to have a lower total light transmittance than the intermediate sheet.
