Interlabial Pad

May 6, 2008

An interlabial pad for attaching between labia was patented. It comprises a water permeable surface side sheet facing a body side; either a water permeable or water impermeable back side sheet facing a garment side; a water permeable inner sheet positioned between the surface side sheet and the back side sheet; and an absorbent body for absorbing body liquid. The absorbent body includes a first absorbent body to form a first protruding area projecting toward the body side from a first flat area. It extends along a substantial center line from one end to another end in a longitudinal direction of the interlabial pad. A second absorbent body forms a first flat area with a substantial plane plate shape. The first protruding area of the first absorbent body has a largest width at a portion closest to the first flat area of the second absorbent body. It provides one hollow part on the garment side of the first protruding area formed in a shape corresponding to the first protruding area with a largest width at a portion closest to the first flat area of the absorbent body. It extends along the center line from one end to another end with openings at each of the ends. The first absorbent body and the second absorbent body are formed by a single sheet enclosed between the surface side sheet and the inner sheet. A third base absorbent body lies on the back side sheet. The second absorbent body is affixed to the third base absorbent body via a portion of the inner sheet. The surface side sheet, the inner sheet and the back side sheet are affixed to each other along edges of the interlabial pad in the longitudinal direction. The first flat area and a first protruding area satisfy Formulas (1) to (3) shown below: 1≤H1/H2≤10 (1) 1/3≤W1/W2≤5/6 (2) 1/3≤L1/L2≤1 (3) H1 is the apparent bulkiness of the first protruding area; H2 is the apparent bulkiness of the first flat area; W1 is the apparent maximum width of the first protruding area; W2 is the apparent maximum width of the first flat area; L1 is the apparent maximum length of the first protruding area; and L2 is the apparent maximum length of the first flat area.
