  • Patent number: 6283952
    Abstract: The invention provides an improved tampon, particularly suited for use as a digital tampon, having a portion of fibers at a withdrawal end of the tampon displaced towards an insertion end, causing a fiber density in the vicinity of the withdrawal end to be lower than an average fiber density of the tampon. The tampon also includes an indentation in the withdrawal end. In combination, the lower fiber density of the withdrawal end and the indentation in the withdrawal end cause the withdrawal end to be soft and readily flareable. When the tampon is provided with an overwrap the indentation also allows excess overwrap at the withdrawal end to be tucked into the tampon, improving the aesthetic qualities of the tampon and facilitating digital insertion.
