Dropwise liquid dispensing system particularly suitable for liquids having low surface tension
First Claim
1. A dropwise liquid dispensing system comprising:
- a liquid formulation having a surface tension of less than a specific value;
tip means for dispensing of the liquid formulation in a dropwise fashion;
inner bottle means, in communication with said tip means, for both containing the liquid formulation and forcing the liquid formulation through the tip means upon compression of the inner bottle means;
means, defining a volume of said inner bottle means, for preventing the liquid formulation from flowing out of the inner bottle means through the tip means without compression of the inner bottle means;
means for facilitating compression of the inner bottle means comprising accordion-like folds in the inner bottle means; and
outer bottle means, disposed around said inner bottle means, for compressing the inner bottle means.

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