Tampon pledget for increased bypass leakage protection
View Patent ↗There is provided a tampon pledget that includes one or more enhanced features that result in the pledget exhibiting increased bypass leakage prevention. These enhanced features may include, but are not limited to, geometry, absorption, and any combinations thereof. There is also provided one or more methods for constructing a tampon pledget having increased bypass leakage protection.
1. A tampon pledget comprising:
a bottom pad;
a top pad, wherein said bottom pad and said top pad comprise material selected from the group consisting of cellulosic, rayon, cotton, pulp, superabsorbent, absorbent foam, and any combinations thereof; and
a pad lay-up ratio being a ratio of an area of said bottom pad to an area of said top pad, said pad lay-up ratio being between about 1:1.2 to about 1:2.25; and
a fiber weight distribution ratio between about 0.5:1 to about 2:1; wherein prior to folding said bottom pad and said top pad to form a compressed tampon pledget, said top pad and said bottom pad are in a cross-pad configuration,
wherein said cross-pad configuration has an overlap portion that is formed where said top pad and said bottom pad overlap one another and a plurality of non-overlap portions are formed on opposite sides of said top pad and said bottom pad where said top pad and said bottom pad do not overlap one another.
2. The tampon pledget according to claim 1 , wherein said pad lay-up ratio is about 1:1.6.
3. The tampon pledget according to claim 1 , wherein said top pad has a length dimension between about 2 inches and about 6 inches and a width dimension between about 1 inch and about 4 inches.
4. The tampon pledget according to claim 1 , wherein said top pad has a length dimension between about 3.5 inches and about 5 inches and a width dimension between about 1.5 inches and about 3 inches.
5. The tampon pledget according to claim 1 , wherein said top pad has a length dimension of about 4 inches and a width dimension of about 2 inches.
6. The tampon pledget according to claim 1 , wherein said bottom pad has a length dimension between about 1 inch and about 4 inches and a width dimension between about 1 inch and about 4 inches.
7. The tampon pledget according to claim 1 , wherein said bottom pads has a length dimension between about 2 inches and about 3 inches and a width dimension between about 1.5 inches and about 3 inches.
8. The tampon pledget according to claim 1 , wherein said bottom pad has a length dimension of about 2.5 inches and a width dimension of about 2 inches.
9. The tampon pledget according to claim 1 , further comprising a fiber weight distribution ratio of a fiber weight distribution of said bottom pads to a fiber weight distribution of said top pads that is between about 0.75:1 to about 1.5:1.
10. The tampon pledget according to claim 1 , further comprising a fiber weight distribution ratio of a fiber weight distribution of said bottom pads to a fiber weight distribution of said top pad that is about 1:1.
11. The tampon pledget according to claim 1 , wherein said bottom pads and said top pads have a pad lay-up configuration selected from the group consisting of cross, chevron, diamond, circular, oval, square, rectangle, and any combinations thereof.
12. The tampon pledget according to claim 1 , further comprising a liquid permeable coverstock.
13. The tampon pledget according to claim 1 , wherein said pledget is expandable to teardrop shape.
14. The tampon pledget according to claim 1 , wherein said pledget is expandable to an hourglass shape.
15. The tampon pledget according to claim 1 , wherein said bottom pads has a bottom overlapping portion between a first bottom end portion and a second bottom end portion and said top pad has a top overlapping portion between a first top end portion and a second top end portion, wherein said top pad and said bottom pad only overlap in said top overlapping portion and said bottom overlapping portion prior to forming the tampon pledget, and wherein said first bottom end portion and said second bottom end portion each have a size that is less than a size of each of said first top end portion and said second top end portion.
