  • Patent number: 8221371
    Abstract: A process for overwrapping a catamenial device such as a tampon includes the steps of providing a substantially cylindrical overwrapper material, inserting a catamenial device into the overwrap material, and closing the open end of the overwrapper material. The overwrapper material has an open end, a closed end, and a first length. The catamenial device has a tapered insertion end, a longitudinal axis, and a length less than the first length, such that the open end of the overwrapper material extends beyond the insertion end of the inserted catamenial device. Concave clamping jaws are applied to the open end of the overwrapper material to urge it toward the longitudinal axis of the catamenial device; to conform portions of the overwrapper material to the insertion end of the catamenial device; and to fold overwrapper material between adjacent clamping jaws to form fins extending outwardly from the conformed portions.

  • Patent number: 7982089
    Abstract: 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.

  • Patent number: 7977532
    Abstract: A catamenial tampon comprises a compressed absorbent member having an inner region and an exterior surface, the compressed absorbent member comprising an absorbent material. An overwrap substantially covers the exterior surface of the compressed absorbent member. The overwrap comprises an apertured fluid pervious material that is hydrophobic or rendered hydrophobic relative to the compressed absorbent member. The fluid pervious overwrap therefore tends to remain free of fluid as the fluid is preferentially partitioned into the absorbent member.
