Applicator for medicinal therapeutic, pharmaceutical, and cosmetic preparations
DCFirst Claim
1. An improved applicator head comprising a hollow applicator head shell having a central cavity, a perimeter wall surrounding the central cavity, an open applicator end at its top and an opposite reservoir end communicating with the central cavity, and a transverse wall within the shell separating the central cavity into an applicator chamber opening into the open application end, and a reservoir chamber opening into the open reservoir end, the transverse wall having at least one opening between the applicator chamber and the reservoir chamber;
- the perimeter wall surrounding the applicator chamber having a plurality of inwardly beveled lips extending upwardly from the perimeter wall, the lips separated from one another;
a foam applicator head having an applicator surface and an opposite face surface, the foam applicator head positioned in the applicator chamber with the applicator surface extending beyond the open applicator end, the lips removably securing the foam applicator head into the applicator chamber, the applicator head having at least one slit extending from the applicator surface through the foam to the base surface, at least a portion of each slit at the base surface positioned on one of said openings in the transverse wall;
the walls of each slit normally compressed together to seal each slit.

Abstract
An improved applicator for medicinal, therapeutic, pharmaceutical, and/or cosmetic preparations comprising an applicator head having a foam applicator head, a flexible tubular reservoir for storing the preparation, and a cap to seal off the applicator end of the applicator head. The foam having one or more slits which form communication passageways between the reservoir and the applicator head and which are compressed by the cap to prevent migration of air from the exterior into the reservoir and passage of preparation from the reservoir to the applicator head when the cap is seated on the applicator head.
