Abstract:
1. An interlabial pad having a longitudinal axis and a lateral axis, comprising: an absorbent body for absorbing body fluid; a surface side sheet and a rear surface side sheet having a first bonding portion each of which bonded surrounding ends of the interlabial pad enclosing the absorbent body; a holding sheet member disposed on the rear surface side sheet having second bonded portions which is bonded surrounding ends of the interlabial pad and having first unbonded portions including an area that keep peripheral edges of the holding sheet member away from peripheral edges of the rear surface side sheet provided near each of two longitudinal surrounding ends of the interlabial pad and second unbonded portions including a pair of laterally opposed unbonded portions located at the rear surface side sheet of the interlabial pad on left and right peripheral side edges near a central area along a longitudinal axis of the interlabial pad; a long protruding area linearly and continuously over the entire length of the longitudinal axis provided by folding the interlabial pad folded in a mountain folded shape toward the surface side sheet along the longitudinal axis, is located on the first unbonded portion of the holding sheet member, the long protruding area having folding guide element is comprised of any of a broken line, a cut line, and a compression line formed into the absorbent body, wherein ends of the second unbonded portions meet ends of the bonded portions along the peripheral side edges; a first fingertip insert opening formed by one of the pair of unbonded portions of the second unbonded portions and arranged between the rear surface side sheet and the holding sheet member; a second fingertip insert opening formed by the other of the pair of unbonded portions of the second unbonded portions and arranged between the rear surface side sheet and the holding sheet member; and wherein the interlabial pad forms a convex protruding area having the long protruding area linearly and continuously over the entire length of the longitudinal axis when the holding sheet member is pinched via the first and second fingertip insert openings, wherein at least one of the absorbent body, surface side sheet, rear surface side sheet and holding sheet member has at least one property of a biodegradable material, a water dispersible material, and a water soluble material, wherein the surface side sheet includes a nonwoven fabric as a water permeable sheet selected from a range in which fiber length is 1 to 15 mm, or a biodegradable resin by a water solution, wherein at least one of the first bonding portion and the second bonding portion are achieved by a single or a combination of a bonding by water soluble or water expanding polyvinylalcohol and a hydrogen bond connecting, and wherein the holding sheet member includes one of a biodegradable or water soluble resin, and a laminated member of the biodegradable or water soluble resin and tissue.
