Abstract
A tampon is disclosed which exhibits low frictional drag during insertion into and withdrawal from a woman's vagina. The tampon includes an absorbent compressed into a generally cylindrical shape and a liquid-permeable cover which surrounds at least a portion of the absorbent. The cover is treated with an aqueous solution having a viscosity of at least 50 cps at a temperature of about 25.degree. C. The solution includes a lubricant and at least about 3 percent by weight of a polymer. The polymer serving to prevent the lubricant from migrating away from the cover such that the tampon retains a sufficient amount of lubricant to facilitate comfortable withdrawal from the vaginal cavity.
Claims19
A tampon exhibiting low frictional drag comprising:
- a) a compressed absorbent;
- and
- b) a cover surrounding at least a portion of said absorbent, said cover being treated with an aqueous solution having a viscosity of at least 50 cps at a temperature of about 25.degree. C., said solution including a lubricant and polyvinyl alcohol, said polyvinyl alcohol preventing said lubricant from migrating away from said cover.
A tampon exhibiting low frictional drag comprising:
- a) an absorbent compressed into a generally cylindrical shape;
- b) a liquid-permeable cover surrounding at least a portion of said absorbent, said cover being treated with an aqueous solution having a viscosity of at least 50 cps at a temperature of about 25.degree. C., said solution including a lubricant and at least about 3 percent of polyvinyl alcohol, said polyvinyl alcohol preventing said lubricant from migrating away from said cover;
- and
- c) withdrawal means for removing said tampon from a woman's vagina, said withdrawal means being attached to said absorbent.
A tampon exhibiting low frictional drag during withdrawal from a woman's vagina, said tampon comprising:
- a) an absorbent compressed into a generally cylindrical shape;
- b) a liquid-permeable cover circumferentially surrounding said absorbent, said cover being treated with an aqueous solution having viscosity of at least 50 cps at a temperature of about 25.degree. C., said solution including a lubricant and at least 3 percent by weight of a polymer having a molecular weight of at least 106,000, said polymer preventing said lubricant from migrating away from said cover;
- and
- c) withdrawal means for removing said tampon from said vagina, said withdrawal means being attached to said absorbent.
A tampon exhibiting low frictional drag during withdrawal from a woman's vagina, said tampon comprising:
- a) an absorbent compressed into a generally cylindrical shape;
- b) a liquid-permeable cover circumferentially surrounding said absorbent, said cover being treated with an aqueous solution having a viscosity of at least 50 cps at a temperature of about 25.degree. C., said solution including myreth-3-myristate and from between about 3 percent to about 10 percent by weight of polyvinyl alcohol having a molecular weight of at least 106,000, said polyvinyl alcohol preventing said myreth-3-myristate from migrating away from said cover;
- and
- c) withdrawal means for removing said tampon from said vagina, said withdrawal means being attached to said absorbent.
