DROPWISE LIQUID DISPENSING SYSTEM PARTICULARLY SUITABLE FOR LIQUIDS HAVING LOW SURFACE TENSION

摘要

A dropwise liquid dispensing system (10) is provided which includes a liquid formulation having a surface tension of less than a specific value. A tip (22) is provided for dispensing of the liquid formulation in a dropwise fashion and an inner bottle (30), in communication with the tip (22), contains the liquid formulation, and forces the liquid formulation through the tip (22) when compressed. The inner bottle (30) is configured with a volume for preventing a liquid formulation from flowing out of the bottle through the tip (22) without compression of the inner bottle (30). An outer bottle (12) is provided and disposed around the inner bottle (30) for compressing the inner bottle (30). The inner (30) and outer (12) bottles are sized for providing hydraulic advantage in compressing the inner bottle (30) with the hydraulic advantage being manifested by the outer bottle (12) having a greater inner surface area than an outer surface of the inner bottle (30).
