Abstract
An applicator is disclosed for inserting a substance into a body cavity. An apparatus for coating paper and a method of forming the paper into an applicator are also disclosed. The applicator is especially useful for inserting a catamenial tampon into a woman's vagina. The applicator includes a tubular member formed from at least one layer of paper and has an interior and an exterior surface. The tubular member is capable of holding the substance which is to be inserted. At least one of the surfaces of the tubular member is coated with a water-insoluble coating which is comprised of from between about 95 to about 98 percent by weight of a polymeric material and from between about 2 to about 5 percent by weight of a slip agent. The coating provides the tubular member with a dry coefficient of kinetic friction ranging from between about 0.35 to about 0.56 and a wet coefficient of kinetic friction ranging from between about 0.78 to about 1.06. These low dry and wet coefficient of kinetic friction values facilitates insertion of the applicator into the body cavity and expulsion of the substance from the applicator.
