Patent ID: 7307197

Claim:
An interlabial pad comprising: an absorbent body having a body fluid storage layer, a labial-following layer, and a diffusion layer positioned between the labial-following layer and the body fluid storage layer wherein a labial-following layer/body fluid storage layer composition ratio of an apparent thickness is between 60/40 and 95/5; a covering material having a water-permeable surface side sheet, for facing the labia of a wearer, and a back face side sheet, for facing the body fluid storage layer; and a side end portion, joining the surface side sheet with the back face side sheet, wherein at least a part of the labial-following layer is positioned between the surface side sheet and the diffusion layer, and the labial-following layer is adapted to deform together with the covering material in accordance with a labia shape of the wearer; the body fluid storage layer is in contact with the diffusion layer, and the diffusion layer is in contact with the labial-following layer to allow movement of body fluid from the labial-following layer to the body fluid storage layer; spaces are formed at both sides of the body fluid storage layer between the body fluid storage layer and the surface side sheet of the covering material, at least one of the spaces becoming smaller when the interlabial pad is folded in two along a folding axis so that the back face side sheet overlaps itself; and the labial-following layer is more flexible than the body fluid storage layer, wherein the garment side of the body fluid storage layer is covered with tissue having 10 to 20 g/m 2 specific weight per unit; a pulp selected from a range of fiber length of 1 to 10 mm is laminated at 60 to 120 g/m 2 by specific weight per unit in the body fluid storage layer on an upper face thereof; a mesh spun lace of rayon with a fiber length of 25 to 51 mm is laid down in the diffusion layer at a body side of the body fluid storage layer; and a mixture at a mixing ratio of 60 to 90% rayon selected from a range of a fiber length of 20 to 51 mm and 40 to 10% of natural cotton is laminated at 150 to 250 g/m 2 by specific weight per unit in the labial-following layer on an upper face thereof.
