Methods of lubricating a tampon and a tampon lubricated thereby
View Patent ↗There is provided a tampon pledget or tampon applicator that is covered by a wrapper having microcapsules thereon. Alternatively, the microcapsules may simply be disposed on the tampon pledget or tampon applicator. The microcapsules may contain a lubricant or a fragrance or a combination of both. The microcapsules may be ruptured prior to inserting the tampon pledget or tampon applicator and the resultant free-flowing lubricant and/or fragrance is spread on the tampon pledget, tampon applicator, or a combination thereof. The lubricant increases the ease and comfort of inserting and positioning the tampon pledget or tampon applicator. The amount of lubricant desired may be controlled by varying the pressure applied to the microcapsules. Thus, the number of microcapsules ruptured can be controlled by varying the pressure applied.
1. A tampon pledget comprising: an exterior surface, said exterior surface having a plurality of microcapsules thereon, a substantial number of said plurality of microcapsules having a lubricant as an only ingredient therein and a remainder of said plurality of microcapsules absent lubricant, wherein said plurality of microcapsules may be ruptured, as desired, for the purpose of spreading said lubricant on said exterior surface, wherein said plurality of microcapsules are on said exterior surface by a binding material, wherein each of said plurality of microcapsules range in size from 500 μm to 800 μm, and wherein said lubricant has a weight of about 40 mg per microcapsule.
2. The tampon pledget according to claim 1 , wherein said lubricant is selected from the group consisting of: mineral oil, vegetable oil, silicone oil, water, propylene glycol, polyglyceryl methacrylate, glyceryl laurate, polysorbate, and any mixture thereof.
3. The tampon pledget according to claim 1 , wherein said remainder of said plurality of microcapsules has fragrance therein.
4. The tampon pledget according to claim 1 , wherein said exterior surface has said remainder of said plurality of microcapsules with fragrance therein, said remainder of said plurality of microcapsules being interspersed with said substantial number of said plurality of microcapsules having lubricant therein.
5. A method of lubricating a tampon comprising the steps of:
providing a plurality of microcapsules that are adhered to an exterior surface of a tampon applicator, said plurality of microcapsules having a substantial number thereof with a lubricant therein and a remainder of said plurality of microcapsules without said lubricant therein; and
rupturing said substantial number of said plurality of microcapsules for the purpose of spreading said lubricant onto a tampon pledget, said tampon applicator, or combination thereof.
6. The method of claim 5 , further comprising varying the pressure exerted on said substantial number of said plurality of microcapsules to control the number of ruptured microcapsules and, thus, the amount of said lubricant desired.
7. The method of claim 6 , wherein the pressure exerted on said substantial number of said plurality of microcapsules is applied by a portion of a wrapper over an insertion end of the tampon.
8. The method of claim 5 , wherein said remainder of said plurality of microcapsules have fragrance therein.
9. The method of claim 5 , wherein said rupturing one or more of said plurality of microcapsules comprises rupturing one or more of said substantial number of said plurality of microcapsules to spread said lubricant onto said tampon pledget.
10. The method of claim 5 , wherein said rupturing comprises using a portion of a wrapper like a tourniquet to squeeze and rupture a number of said plurality of microcapsules.
11. The method of claim 5 , wherein each of said plurality of microcapsules range in size from about 500 μm to about 800 μm.
12. A method of lubricating a tampon comprising the steps of:
providing a plurality of microcapsules on an interior surface of a wrapper covering said tampon, said plurality of microcapsules having a substantial number thereof with a lubricant therein and a remainder of said plurality of microcapsules without said lubricant therein;
opening said wrapper at about a midpoint of said wrapper and leaving a portion of said wrapper over an insertion end of said tampon and discarding another portion of said wrapper; and
rupturing said substantial number of said plurality of microcapsules that comprises applying pressure to said portion of said wrapper over said insertion end of said tampon and simultaneously twisting said wrapper so that said substantial number of said plurality of microcapsules adhered thereto are ruptured resulting in free-flowing lubricant that is spread onto said tampon pledget, said tampon applicator, or combination thereof.
13. The method of claim 12 , further comprising varying said pressure and said simultaneous twisting force applied to said wrapper to control an amount of said plurality of microcapsules ruptured.
