Tampon pledget with improved by-pass leakage protection
View Patent ↗A tampon pledget is made by assembling one or more pads in a pad compression configuration, radially compressing the pad compression configuration in a traverse direction into a cylindrical form, and axially compressing the cylindrical form in a direction along a vertical axis to form the tampon pledget. In one embodiment, the axial compression is performed as a pressure is applied to at least one of a first and a second end of the cylindrical form. In one aspect of the present invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 6.0 grams to 9.0 grams and a density of about 0.4603 grams/cubic centimeter. In another aspect of the invention, the formed tampon pledget has an absorbent capacity as measured by the syngyna test of between about 9.0 grams to 12.0 grams and a density of about 0.4755 grams/cubic centimeter.
1. A tampon pledget, comprising:
a first pad having a length and a width; and
a second pad having a length and a width,
wherein said first pad is placed perpendicular to said second pad thereby forming a cross configuration said pads being radially and then axially compressed into a generally cylindrical form, wherein after compression, the cylindrical form has an absorbent capacity as measured by the syngyna test of between about 6.0 grams to 9.0 grams, and a density of about 0.4603 grams/cubic centimeter, and at least one of a maximum displacement volume exceeding about 3.00 milliliters, and a rate of displacement exceeding about 0.55 milliliters per minute; and
wherein said tampon pledget blooms in a radial direction when it absorbs fluid such that it blooms to an increase of 90% or more.
2. The tampon pledget of claim 1 , further comprising a leak shield covering at least a portion of the tampon pledget and having a second absorbency, the second absorbency being less than an absorbency of the tampon pledget, the leak shield comprising a nonwoven material that directs fluid to the tampon pledget when the tampon pledget is inserted in a vaginal cavity of a wearer.
3. The tampon pledget of claim 1 , wherein said cylindrical form has a first end geometry that is blunt, conical, tapered, curved, an inverse thereof and/or combinations thereof.
4. The tampon pledget of claim 1 , wherein said cylindrical form further comprises a withdrawal string.
5. A tampon pledget, comprising:
a first pad having a length and a width; and
a second pad having a length and a width,
wherein said first pad is placed perpendicular to said second pad thereby forming a cross configuration said pads being radially and then axially compressed into a generally cylindrical form, wherein after compression, the cylindrical form has an absorbent capacity as measured by the syngyna test of between about 9.0 grams to 12.0 grams, and a density of about 0.4755 grams/cubic centimeter, and at least one of a maximum displacement volume exceeding about 4.20 milliliters, and a rate of displacement of exceeding about 0.65 milliliters per minute; and
wherein said tampon pledget blooms in a radial direction when it absorbs fluid such that it blooms to an increase of 75% or more.
6. The tampon pledget of claim 5 , further comprising a leak shield covering at least a portion of the tampon pledget and having a second absorbency, the second absorbency being less than an absorbency of the tampon pledget, the leak shield comprising a nonwoven material that directs fluid to the tampon pledget when the tampon pledget is inserted in a vaginal cavity of a wearer.
7. The tampon pledget of claim 5 , wherein said cylindrical form has a second end geometry that is blunt, conical, tapered, curved, an inverse thereof and/or combinations thereof.
8. The tampon pledget of claim 5 , wherein said cylindrical form further comprises a withdrawal string.
9. A tampon pledget, comprising:
a first pad having a length and a width; and
a second pad having a length and a width,
wherein said first pad is placed perpendicular to said second pad thereby forming a cross configuration said pads being radially and then axially compressed into a generally cylindrical form, wherein after compression, the cylindrical form has an a density of greater than or equal to 0.4603 grams/cubic centimeter, and at least one of a maximum displacement volume exceeding about 3.00 milliliters, and a rate of displacement exceeding about 0.55 milliliters per minute; and
wherein said tampon pledget blooms in a radial direction when it absorbs fluid such that it blooms to an increase of 75% or more.
10. The tampon pledget of claim 9 , further comprising a leak shield covering at least a portion of the tampon pledget and having a second absorbency, the second absorbency being less than an absorbency of the tampon pledget, the leak shield comprising a nonwoven material that directs fluid to the tampon pledget when the tampon pledget is inserted in a vaginal cavity of a wearer.
11. The tampon pledget of claim 9 , wherein said cylindrical form has a second end geometry that is blunt, conical, tapered, curved, an inverse thereof and/or combinations thereof.
12. The tampon pledget of claim 9 , wherein said cylindrical form further comprises a withdrawal string.
13. A tampon pledget, comprising:
a first pad having a length and a width; and
a second pad having a length and a width,
wherein said first pad is placed perpendicular to said second pad thereby forming a cross configuration, said pads being radially and then axially compressed into a generally cylindrical form having a shaped insertion end and a removal end, wherein after compression, the cylindrical form has a density greater than or equal to about 0.42 grams/cubic centimeter, and at least one of a maximum displacement volume exceeding about 3.00 milliliters and a rate of displacement exceeding about 0.55 milliliters per minute; and
wherein said tampon pledget blooms in a radial direction when it absorbs fluid such that it blooms to an increase exceeding 61%.
14. The tampon pledget according to claim 13 , wherein at least one of said length and said width of said first pad and said second pad are substantially equal.
15. The tampon pledget according to claim 13 , wherein said length of said first pad is about 4 inches.
16. The tampon pledget according to claim 13 , wherein said width of said first pad is about 2 inches.
