Patent ID: 7648490

Claim:
A sanitary napkin comprising: a napkin body having a liquid-absorbent layer for absorbing and retaining liquid; and a first projection and a second projection, each of the projections extending in a longitudinal direction and each comprising an elastic member for exerting an elastic contractive force between longitudinally opposing front and rear ends to concavely curve the body surface of the napkin body and raise itself from the body surface of the napkin body, wherein: the first projection is formed with a top sheet and a tube-like shaped surface material which extends longitudinally and exerts an elastic contractive force between the front and rear ends to form the projection, the napkin body has an overlap region where a portion of the second projection extending forward from the rear end of the second projection lies laterally opposite to a portion of the first projection extending rearward from the front end of the first projection, and wherein a portion of the second projection extending rearward from the front end of the second projection and a portion of the first projection extending forward from the rear end of the first projection each lie outside of the overlap region, the napkin body has front and rear regions on longitudinally opposite sides of the overlap region; front and rear ends of the front region are defined by the front end of the second projection and the front end of the first projection, respectively; front and rear ends of the rear region are defined by the rear end of the second projection and the rear end of the first projection, respectively, wherein the napkin body has compression lines which extend longitudinally at least in the front region, and the napkin body further comprises a third projection which also exerts an elastic contractive force between longitudinally opposing front and rear ends to concavely curve the body surface of the napkin body, wherein a midpoint between the front and rear ends of the first projection and a midpoint between the front and rear ends of the third projection are each located behind a midpoint between the front and rear ends of the second projection.
