Abstract

Absorbent products having integral belt means for retaining the absorbent product in a position to absorb body fluids are disclosed. In a preferred embodiment, a napkin is provided wherein straps are cut from the material of the napkin. These straps are then tied around the body of the user when the napkin is applied. The straps are flexible enough to allow them easily to be tied to each other on the side. The straps may or may not be retained by the waistband of an undergarment. Alternatively, a second embodiment is provided wherein long flap-like straps extend longitudinally away from the transverse ends of the absorbent product. These straps are then engaged by the elastic waistband on an undergarment, to retain the napkin in place. Methods of manufacturing absorbent products are also disclosed.
