Abstract
A shaped sanitary napkin. The sanitary napkin of this invention has an absorbent means, such as an absorbent core, and two flaps extending outwardly from the absorbent means. Each flap is associated with the absorbent means along a nonlinear line of juncture and each has two axes of flexibility. In use, the absorbent means is secured in the crotch of a panty and the flaps are secured about the elastic edges of the panty so that, when the panty is worn, the absorbent means is held adjacent the body while the flaps form a wall at each side of the absorbent means and seals against the body. Both the walls and the seals serve to prevent soiling of the body and clothing by menstrual fluid.
Claims33
An absorbent article comprising:
- a) a central absorbent pad having longitudinal edges and a pair of flaps extending laterally outward from said longitudinal edges, said central absorbent pad having a body contacting surface and a garment surface, said flaps having a resistance to bending, through an arc of 90°, of between about 20 grams and about 200 grams;
- and
- b) attachment means for securing the absorbent article to an undergarment, said attachment means being positioned on each of said flaps.
An absorbent article comprising:
- a) a liquid pervious topsheet;
- b) a liquid impervious backsheet;
- c) an absorbent core positioned between said topsheet and said backsheet;
- thereby forming a central absorbent pad having longitudinal edges and a pair of flaps extending laterally outward from said longitudinal edges, said central absorbent pad having a body contacting surface and a garment surface, said flaps having a resistance to bending, through an arc of 90°, of between about 20 grams and about 200 grams;
- d) attachment means for securing said pad to an undergarment, said attachment means being positioned on said garment surface on both of said flaps;
- and
- e) release paper covering said attachment means.
