发明名称 Coating method
摘要 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. In one embodiment, multiple layers form the exterior surface coating. In one embodiment, the exterior surface coating has a thickness varying in dimension from the insertion end to the opposite external base end.
