Abstract:
1. An absorbent article comprising a liquid-permeable top sheet, a liquid-impermeable back sheet, an absorber interposed therebetween, and a flap surrounding the absorber without including the absorber; and wherein the flap has a wave-like outline contour along each of a frontmost distal edge and a backmost distal edge; wherein each said wavelike contour is composed of convex outline lengths and concave outline lengths and has a peripheral tangential line that continuously changes; wherein at a front portion of the flap extending to the frontmost distal edge, flap width gradually narrows to form a frontmost distal convex curve portion, and wherein to each side of said frontmost distal convex curve portion are convex outline lengths and concave outline lengths of said frontmost distal edge wave-like outline contour; and wherein at a back portion of the flap extending to the backmost distal edge, flap width gradually narrows to form a backmost distal convex curve portion, and wherein to each side of said backmost distal convex curve portion are convex outline lengths and concave outline lengths of said backmost distal edge wave-like outline contour.
