Controlled drop dispensing container
Abstract:
The present invention relates to packaging materials for ophthalmic solutions. Difficulties with water loss in standard ophthalmic bottles are overcome in the controlled drop dispensing container of the present invention. This controlled drop dispensing container comprises a dispensing tip, a laminate tube 15, and a shoulder connecting the laminate tube 15 to the dispensing tip 7. The dispensing tip 7 comprises an inner orifice having a diameter sufficiently small to restrict flow of liquid contents of the tube to the desired level, an outer orifice 9 having a diameter sufficiently large to form a drop of the desired size from the liquid contents of the tube, where fluid communication exists between the inner orifice and the outer orifice 9. The laminate tube 15 comprises an outer polymeric layer 10, an optional first tie layer 11, a middle barrier layer 12, an optional second tie layer 13, an inner polymeric layer 14. Preferably, the controlled drop dispensing container 1 also comprises a cap 4 and a reusable seal 3 between the cap 4 and the dispensing tip 7. In another preferred embodiment of the invention, the cap 4 also comprises a tamper evident tear strip 5.
