Abstract
There is provided a tampon having a plurality of pledget segments with each segment having one or more layers of absorbent material and one or more layers of semipermeable material. The one or more semipermeable layers of each segment forms an absorption restriction boundary to the next adjacent segment that allows each segment to absorb and expand independently from the other segments. The plurality of pledget segments can be positioned in a coverstock bag.
Claims36
A tampon comprising:
- a plurality of segments positioned at unoccupied intervals along an axis, each of said plurality of segments having an absorbent layer and a layer of semipermeable material, and
- wherein said layer of semipermeable material acts as an absorption barrier that restricts and delays substantial fluid absorption by the absorbent layer of a next one of said plurality of segments until said absorbent layer of a preceding one of said plurality of segments has substantially absorbed and expanded.
A tampon comprising:
- a coverstock bag, a withdrawal cord attached to said coverstock bag, and a plurality of segments positioned in said coverstock bag, each of said plurality of segments having at least one absorbent layer and at least one layer of semipermeable material, and
- wherein said at least one layer of semipermeable material acts as an absorption barrier that restricts and delays substantial fluid absorption by the absorbent layer of a next one of said plurality of segments until said at least one absorbent layer of a preceding one of said plurality of segments has substantially absorbed and expanded.
