An applicator is disclosed for inserting a substance into a body cavity. 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 which has an exterior surface. The tubular member is capable of holding the substance which is to be inserted. The exterior surface of the tubular member is coated with a compostable coating which is comprised of at least about 98 percent by weight of a polymeric material. The coating provides the tubular member with a dry coefficient of kinetic friction ranging from between about 0.62 to about 0.86 and a wet coefficient of kinetic friction ranging from between about 0.69 to about 1.12. These low dry and wet coefficients of kinetic friction values facilitate insertion of the applicator into the body cavity. Also disclosed is an apparatus for coating a strip of paper and a method of forming a paper applicator containing a compostable coating.
Applicateur conçu pour introduire un matériau dans une cavité corporelle. Cet applicateur convient notamment à l'introduction d'un tampon cataménial dans le vagin. Ledit applicateur comprend un élément tubulaire formé d'au moins une couche de papier à face externe. Cet élément tubulaire peut contenir la substance à introduire. La face externe de l'élément tubulaire est revêtue d'un revêtement compostable dont au moins 98 % en poids est en matière polymère. Ce revêtement confère à l'élément tubulaire un coefficient de frottement dynamique à sec compris entre 0,62 et 0,86 environ, et un coefficient de frottement dynamique à l'état humide compris entre 0,69 et 1,12 environ. Ces faibles valeurs du coefficient de frottement dynamique à sec et à l'état humide facilitent l'introduction de l'applicateur dans la cavité corporelle. On décrit également un appareil pour le revêtement d'une bande de papier, et un procédé de formation d'un applicateur en papier à revêtement compostable.
