发明名称 SANITARY NAPKIN COMPRISING THREE-DIMENSIONALLY SHAPED TUBE OF ABSORBENT MATERIAL
摘要 A tube of absorbent material extends outward from the body-facing side of the base pad and is aligned along the longitudinal centerline of the base pad. In one embodiment, the tube of absorbent material comprises an absorbent material and a cover at least partially wrapping the absorbent material. In this embodiment, the absorbent material is penetrated by autogenous bonds that join one portion of the cover to an opposing portion of the cover. The bonds are selectively placed to provide the tube of absorbent material with a distinct three-dimensional shape. The method of making a shaped tube of absorbent material for the sanitary napkin, in one embodiment, involves the steps of: (a) providing a web of absorbent material; (b) providing a cover for the first and second surfaces of the web of absorbent material; (c) at least partially covering the first and second surfaces of the web of absorbent material with the cover to form a composite web having longitudinal side margins; (d) folding the composite web at least once with folds defining fold lines that are arranged about the longitudinal centerline of the web of absorbent material; and (e) autogenously bonding a portion of the cover that covers the first surface of the web of absorbent material to a portion of the cover that covers an opposing portion of the second surface of the web of absorbent material.
