ABSTRACT:
A liquid dispensing container particularly for single-use dispensing of eye medication and self-application of eye drop. The container for the liquid storage cavity has a molded plastic housing and at least one metallic foil wall secured to form an exterior wall of the housing and a flexible cavity wall. The foil wall is manually squeezable or deformable to enable a reduction in the volume of the cavity and compression and displacement of the medication therefrom. The foil wall is impervious to water vapor transmission out of the cavity which extends the shelf life of the stored container. The foil wall is also conveniently printed with labelling text and color. The plastic housing has an integrally molded nozzle which combine to control displaced flow and drop size of the dispensed medication.
