  • Patent number: 9610201
    Abstract: A tampon absorbent for insertion into a vaginal cavity is provided. The tampon absorbent includes a longitudinal direction and has an insertion end and a withdrawal end. The tampon absorbent includes a first absorbent material portion at the insertion end for capturing body fluid and demonstrating a first expansion capacity, and a second absorbent material portion at the withdrawal end for storing body fluid and demonstrating a second expansion capacity. The second absorbent material portion is partially wrapped around the first absorbent material portion in a direction transverse (perpendicular) to the longitudinal direction, at a bonding region, whereby the first absorbent material portion is bonded to the second absorbent material portion at the bonding region.
    Type: Grant
    Filed: April 30, 2012
    Date of Patent: April 4, 2017
    Assignee: Kimberly-Clark Worldwide, Inc.

  • Patent number: 8293968
    Abstract: A dual mode absorbent tampon comprising a mass of absorbent material compressed into a generally cylindrical shape, in a first mode of the tampon. The mass of absorbent material comprising a homogeneous mixture of a plurality of fibers which comprise at least a first type of fiber and a second type of fiber, where the first type of fiber is bondable to fibers of the plurality of fibers. At least a portion of the first type of fibers are bonded in a pre-determined pattern to adjacent fibers of the plurality of fibers wherein absorption by the tampon causes at least a portion of the mass of absorbent material to expand into a non-cylindrical shape which is dependent upon the pre-determined pattern, in a second mode of the tampon.
