  • Absorbent article with a concave groove
    Patent number: 10806642
    Abstract: A absorbent article has a concave groove that satisfies (1) a relationship between a depth “h” of a bottom surface portion of the concave groove, and a distance “S” from a bottom end “G” of the concave groove to an upper end “K” from which a concavity of the concave groove starts is 1.5h<S, (2) a relationship between a width “b” of a bottom surface of the concave groove, and a width “B” of a liquid collection area expressed by a distance between the upper ends “K” and “K” at both sides of the concave groove is B?3b, and (3) a relationship between a dimension “a” of a square concave groove expressed by a product of the width “b” of the bottom surface and the depth “h” of the bottom surface, and a cross-sectional dimension “A” of the concave groove is A?2a.
