Abstract
A liquid dispensing container particularly for single-use dispensing if eye medication and self-application if eye drop. The container for the liquid storage cavity has a molded plastic housing and a flexible cavity wall. The 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 plastic housing has an integrally molded nozzle which combine to control displaced flow and drop size of the dispensed medication.
