Shaped tampon
Shaped tampons having varying perimeters are provided. Tampons disclosed comprise a mass of absorbent material formed into a self-sustaining shape comprising an insertion end, a withdrawal end, and a center region. The center region has at least one perimeter which is less than a largest insertion end perimeter and is less than a withdrawal end perimeter. The shaped tampons may also have varying average fiber density regions. The shaped tampons may be wrapped in tightly conforming wrappers which optionally aid in maintaining the self-sustaining shape prior to use. Optionally, the shaped tampons may utilize tampon applicators which enable a user to visually see the shape of the tampon prior to use.
1. A tampon wholly insertable in a body cavity comprising a mass of absorbent material formed into a compressed self-sustaining shape, said self-sustaining shape comprising:
an insertion end wherein said insertion end is closed, a withdrawal end, and a center region, wherein the insertion end is opposed to the withdrawal end and the center region is located between the insertion end and the withdrawal end;
the center region having at least one perimeter which is less than both a largest insertion end perimeter and a withdrawal end perimeter.
2. A tampon according to claim 1 wherein the withdrawal end is asymmetric about an Y axis of the tampon.
3. A tampon according to claim 1 having a withdrawal edge which has a smaller perimeter than at least one withdrawal end perimeter.
4. A tampon according to claim 1 wherein having a substantially serpentine outer surface.
5. A tampon according to claim 1 wherein at least one of the center region perimeters is from about 5% to about 25% smaller than the largest insertion end perimeter.
6. A tampon according to claim 1 wherein at least one of the center region perimeters is from about 5% to about 25% smaller than the withdrawal end perimeter.
7. A tampon according to claim 5 wherein at least one of the center region perimeters is from about 10% to about 15% smaller than the largest insertion end perimeter and/or a largest withdrawal end perimeter.
8. A tampon according to claim 1 having a maximum perimeter region which has a maximum perimeter region average fiber density, and a minimum perimeter region which has a minimum perimeter region average fiber density;
wherein the minimum perimeter region average fiber density is greater than the maximum perimeter region average fiber density.
9. A tampon according to claim 1 wherein the withdrawal end has a withdrawal end average fiber density, which is less than the minimum perimeter region average fiber density.
10. A tampon according to claim 8 wherein the minimum perimeter region average fiber density is from about 105% to about 150% of the maximum perimeter region average fiber density.
11. A tampon according to claim 9 wherein the minimum perimeter average fiber density is from about 105% to about 150% of the withdrawal end average fiber density.
12. A tampon according to claim 9 wherein the minimum perimeter region average fiber density is from about 110% to about 130% of a maximum perimeter region average fiber density and/or the withdrawal end average fiber density.
13. A tampon according to claim 8 wherein a the maximum perimeter region and the withdrawal end comprise rayon having a first average fiber density and the minimum perimeter region comprises a cotton/rayon blend having a second average fiber density which is greater than the first average fiber density.
14. A tampon according to claim 6 further comprising texturing on the outer surface.
15. A tampon according to claim 1 wherein the insertion end has a first perimeter about 5 mm from a second perimeter; wherein the first perimeter is equal to the second perimeter.
16. A tampon according to claim 1 wherein the withdrawal end is flared and the insertion end is tapered.
17. A tampon according to claim 1 housed in an applicator wherein the applicator is at least partially translucent, allowing at least a portion of the tampon to be visible to a user prior to use.
18. A tampon according to claim 1 housed in an applicator, wherein the applicator comprises an insertion end comprising flexible material;
and wherein at least a portion of the flexible material conforms to at least a portion of the substantially serpentine outer surface of the tampon, enabling a user to observe at least a portion of the substantially serpentine outer surface of the tampon through the flexible material prior to expulsion of the tampon from the applicator.
19. A tampon according to claim 1 wrapped in a tightly conforming wrapper.
20. A tampon according to claim 19 wherein the tightly conforming wrapper aids in maintaining the self-sustaining shape prior to use.
