Abstract

An absorbent article is disclosed for absorbing body fluids discharged from a human body. The absorbent article includes an absorbent having first and second longitudinally-extending sides, first and second distally spaced ends and a garment-facing surface. The absorbent article includes a structure which interacts with an adjacent undergarment for retaining the absorbent in the crotch region of a human body. The structure includes at least two grooves or channels formed in the garment-facing surface of the absorbent which are sized and configured to receive the side edges of an undergarment. When the undergarment is pulled up around the torso of the user, the side edges of the undergarment will nest in the grooves or channels and hold the absorbent article securely in place, thereby decreasing the likelihood of leakage.

Claims

1. An absorbent article comprising:

a) an absorbent having first and second longitudinally-extending sides and first and second distally spaced ends, said absorbent having a garment-facing surface; and

b) means for retaining said absorbent in the crotch region of a human body, said means including first and second channels formed in said garment-facing surface of said absorbent which are sized and configured to receive edges of an undergarment, each of said first and second channels having a depth into a thickness of said absorbent.

2. The absorbent article of claim 1 wherein said first and second channels are linear.

3. The absorbent article of claim 1 wherein said first and second channels are non-linear.

4. The absorbent article of claim 1 wherein said first and second channels are aligned parallel to one another.

5. An absorbent article comprising:

a) a cover;

b) an absorbent positioned below said cover having first and second longitudinally-extending sides and first and second distally spaced ends, said absorbent having a garment-facing surface; and

c) means for retaining said cover against the crotch region of a human body, said means including first and second channels formed in said garment-facing surface of said absorbent which are sized and configured to receive edges of an undergarment, and each of said first and second channels having a depth into a thickness of said absorbent.

6. The absorbent article of claim 5 wherein said first and second channels are arcuate in shape.

7. The absorbent article of claim 5 wherein said longitudinally-extending sides of said absorbent are non-linear and said first and second channels are aligned parallel to said non-linear sides.

8. The absorbent article of claim 5 wherein said first and second channels are aligned at an angle to one another.

9. The absorbent article of claim 5 wherein said first and second channels extend between said first and second ends of said absorbent.

10. The absorbent article of claim 5 wherein said absorbent has a length and each of said first and second channels extend a distance which is from between about 25 percent to 100 percent of said length.

11. An absorbent article comprising:

a) a cover;

b) an absorbent positioned below said cover having a longitudinally extending central axis, first and second longitudinally-extending sides and first and second distally spaced ends, said absorbent having a garment-facing surface; and

c) means for retaining said cover against the crotch region of a human body, said means including first and second channels formed in said garment-facing surface of said absorbent which are sized and configured to receive edges of an undergarment, each of said first and second channels being located on opposite sides of said longitudinal axis, and having a depth into a thickness of the absorbent.

12. The absorbent article of claim 11 wherein each of said first and second channels has a length of at least 3 inches.

13. The absorbent article of claim 11 wherein each of said first and second channels has a depth into the thickness of the absorbent of from between about 0.1 inches to about 0.5 inches.

14. The absorbent article of claim 11 wherein said absorbent has a plurality of channels formed therein.

15. An absorbent article comprising:

a cover;

an absorbent positioned below said cover having first and second longitudinally-extending sides and first and second distally spaced ends, said absorbent having a garment-facing surface; and

means for retaining said cover and absorbent against the crotch region of a human body, said means including first and second channels formed in said garment-facing surface of said absorbent which are sized and configured to receive edges of an undergarment, and each of said first and second channels spaced inward at least about 0.25 inches from said respective first and second longitudinally-extending sides.

16. An absorbent article comprising:

a cover;

an absorbent positioned below said cover having first and second longitudinally-extending sides and first and second distally spaced ends, said absorbent having a garment-facing surface; and

means for retaining said cover and absorbent against a crotch region of a human body, said means including first and second channels formed in said garment-facing surface of said absorbent which are sized and configured to receive edges of an undergarment, and each of said first and second channels spaced inward at least about 0.5 inches from said respective first and second longitudinally-extending sides.

17. An absorbent article comprising:

a cover;

an absorbent positioned below said cover having a longitudinally extending central axis, first and second longitudinally-extending sides and first and second distally spaced ends, said absorbent having a garment-facing surface; and

means for retaining said cover against the crotch region of a human body, said means including first and second channels formed in said garment-facing surface of said absorbent which are sized and configured to receive edges of an undergarment, each of said first and second channels being located on opposite sides of said longitudinal axis, and each of said first and second channels including an embossment formed into said absorbent.
