Patent ID: 8486037

Claim:
An absorbent article comprising: wing-like flaps that are respectively disposed on both side edges of a main body in which an absorber is interposed between a liquid-permeable front sheet and a back sheet and are to be fixed to an undergarment by wrapping around an inner surface of a crotch portion of the undergarment when the article is worn; seat-holding flaps that are respectively disposed on both side edges of the main body posteriorly of the wing-like flaps and that are to be fixed to an inner surface of a seat portion of the undergarment when the article is worn; a main body displacement-preventing adhesive layer on the back sheet adjacent the back side of the absorber; wing displacement-preventing adhesive layers on the back sides of the wing-like flaps; seat displacement-preventing adhesive layers on the back sides of the seat-holding flaps; and removable release paper sheets covering the main body displacement-preventing adhesive layer, the wing displacement-preventing adhesive layers, and the seat displacement-preventing adhesive layers, wherein the release paper sheets are constituted of a first release paper sheet covering all the main body displacement-preventing adhesive layer and the wing displacement-preventing adhesive layers so that each of the main body displacement-preventing adhesive layer and the wing displacement-preventing adhesive layer are exposed upon removal of the first release paper sheet in to enable adherence of the main body displacement-preventing adhesive and the wing displacement-preventing adhesive layer to the undergarment in a non-worn state of the undergarment., and a pair of second release paper sheets respectively covering the seat displacement-preventing adhesive layers so that the seat displacement-preventing adhesive layers are exposed separately from the main body displacement-preventing adhesive layer and the wing displacement-preventing adhesive layer upon removal of the second release paper sheets, and wherein the seat-holding flaps and the second release paper sheets are each respectively folded to the back side of the absorbent article, and the ends of the second release paper sheets protrude from the side edges of the seat-holding flaps, said removal of the second release paper sheets occurring upon the undergarment being positioned in a worn state of the undergarment for enabling the seat displacement-preventing layers to be fitted to a contour of the undergarment at the seat portion thereof.
