Patent number: 7982089Abstract: 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.Type: GrantFiled: January 9, 2004Date of Patent: July 19, 2011Assignee: Playtex Products, Inc.Inventors: Suzanne Pauley, Jacqueline Davis, Dane R.
