Abstract

The present invention pertains to a compound sanitary napkin. The compound sanitary napkin comprises a primary absorbent member including an absorbent core and an outer cover. The primary absorbent member has a second portion and an first portion; the first portion being vertically opposed to the second portion. The width of the first portion is greater than the width of the second portion. The compound sanitary napkin further comprises a secondary absorbent member that is joined with the primary absorbent member juxtaposed the second portion. The secondary absorbent member preferably comprises a liquid impervious backsheet and an absorbent material joined thereto. Optionally, the secondary absorbent member includes a backsheet, a topsheet joined to the backsheet and an absorbent core disposed between the backsheet and the top sheet.

Claims

1. A compound sanitary napkin comprising a primary absorbent member and a secondary member;

said primary absorbent member having a body facing side and a secondary absorbent member facing side, said primary absorbent member including an absorbent core and an outer cover, said body facing side defined as the side of said primary absorbent member which is most vertically opposed to said secondary absorbent member, said secondary absorbent member facing side defined as the side of said primary absorbent member which is juxtaposed said secondary absorbent member, said body facing side having a first width and said secondary absorbent member facing side having a second width, said first width being greater than said second width; and

said secondary absorbent member having a primary absorbent member facing side, a garment facing side and a periphery defined by a pair of longitudinally extending edges and a pair of end edges, said secondary absorbent member comprising a liquid impervious backsheet, a liquid pervious topsheet joined directly with said backsheet in at least a portion of said periphery and an absorbent element positioned between said topsheet and said backsheet, said secondary absorbent member being joined with at least a portion of said secondary absorbent member facing side of said primary absorbent member, said longitudinal edges of said secondary absorbent member being disposed laterally outboard of said primary absorbent member such that said secondary absorbent member is wider than said primary absorbent member.

2. The compound sanitary napkin of claim 1 wherein said primary absorbent member comprises a containment layer.

3. The compound sanitary napkin of claim 1 wherein said primary absorbent member comprises an acquisition layer.

4. The compound sanitary napkin of claim 1 comprising a resilient member.

5. The compound sanitary napkin of claim 4 wherein said resilient member comprises a polyurethane foam.

6. The compound sanitary napkin of claim 1 wherein said primary absorbent member comprises a plurality of absorbent core members.

7. The compound sanitary napkin of claim 6 wherein said primary absorbent member comprises at least one first core member and at least one second core member, said second core member being compressible under normal wearing forces and said first core member being sufficiently resilient such that when subjected to normal wearing forces said first core member does not permanently collapse.

8. The compound sanitary napkin of claim 7 wherein said first core member is of generally arcuate cross-section.

9. The compound sanitary napkin of claim 7 wherein said first core member comprises a foam.

10. The compound sanitary napkin of claim 7 wherein said first core member is wrapped in a containment layer.

11. The compound sanitary napkin of claim 7 wherein said first core member is wrapped in an acquisition layer.

12. The compound sanitary napkin of claim 6 comprising a resilient member.

13. A compound sanitary napkin comprising a primary absorbent member and a secondary member;

said primary absorbent member having a body facing side and a secondary absorbent member facing side, said primary absorbent member including an absorbent core comprising at least one first core member, and at least one second core member; and

an outer cover;

said body facing side defined as the side of said primary absorbent member which is most vertically opposed to said, secondary absorbent member, said secondary absorbent member facing side defined as the side of said primary absorbent member which is juxtaposed said secondary absorbent member, said body facing side having a first width and said secondary absorbent member facing side having a second width, said first width being greater than said second width; and

said secondary absorbent member having a primary absorbent member facing side, a garment facing side and a periphery defined by a pair of longitudinally extending edges and a pair of end edges, said secondary absorbent member comprising a liquid impervious backsheet, a liquid pervious topsheet joined directly with said backsheet in at least a portion of said periphery and an absorbent element positioned between said topsheet and said backsheet, said secondary absorbent member being joined with at least a portion of said secondary absorbent member facing side of said primary absorbent member, said longitudinal edges of said secondary absorbent member being disposed laterally outboard of said primary absorbent member such that said secondary absorbent member is wider than said primary absorbent member.

14. The compound sanitary napkin of claim 13 wherein said second core member is compressible under normal wearing forces and said first core member is sufficiently resilient such that when subjected to normal wearing forces it does not permanently collapse.

15. The compound sanitary napkin of claim 13 wherein at least one of said first core members is generally in the shape of a parallelepiped.

16. The compound sanitary napkin of claim 13 wherein said first core members comprise a foam.

17. The compound sanitary napkin of claim 13 wherein said first core member comprises a different material than said second core member.
