  • Patent number: 6689036
    Abstract: An applicator article and method are disclosed for inserting a substance into a body cavity. The applicator article and method are especially useful for inserting a catamenial tampon into a woman's vagina. The applicator article includes a tubular member formed from at least one layer of paper which has an exterior surface. The tubular member is capable of holding the substance to be inserted into the body cavity. An exterior surface coating of the tubular member includes a compostable coating composed of at least 85 percent by weight of a polymeric blend material of polylactide, at least 10 percent by weight of additives, and up to about 5 percent by weight of a residual monomer. The coating provides the tubular member with a dry coefficient of kinetic friction value ranging from between 0.62 to 0.86. In one embodiment, a water-soluble polyethylene oxide, a water-soluble polyvinyl alcohol, or a combination of polyethylene oxide and polyvinyl alcohol.

  • Patent number: 5928183
    Abstract: A tampon applicator is disclosed which includes first and second telescopically assembled members. The first member is designed to house an absorbent tampon. The first member has first and second spaced apart ends and is formed from at least two separate and distinct layers. An insertion tip is integrally formed on the first end of the first member and extends outwardly therefrom. The insertion tip is constructed from at least one of the two distinct layers and has a thickness which is less than that of the first member. The second member is telescopically mounted in the second end of the first member and is adapted to expel the tampon through the insertion tip as it is pushed into the first member.

  • Patent number: 5792096
    Abstract: A tampon applicator is disclosed which has an improved pleated tip for facilitating insertion of a catamenial tampon into a woman's vagina. The tampon applicator includes a first member capable of housing an absorbent tampon. The first member has a central longitudinal axis and first and second ends. An insertion tip is integrally formed on the first end of the first member and extends outwardly therefrom. The insertion tip includes a semi-spherical shaped portion and a frusto-conical shaped portion. The semi-spherical shaped portion has an aperture extending therethrough and the aperture has a side wall which is aligned essentially parallel to the central longitudinal axis. The frusto-conical shaped portion is situated between the semi-spherical shaped portion and the first end of the first member. The insertion tip contains a plurality of pleats which are capable of expanding radially outwardly as the tampon is expelled from the first member.
