Abstract
A method for dispensing fluid, including flowing fluid from at least one reservoir to a fluid feed chamber of a piezoelectric sprayer device during a spray cycle, and at an end portion of the spray cycle, reversing the direction of flow of the fluid such that the fluid is substantially removed from the fluid feed chamber.
Claims32
A method for dispensing fluid, comprising:
- flowing fluid from at least one reservoir to a fluid feed chamber of a piezoelectric sprayer device during a spray cycle;
- and
- at an end portion of the spray cycle, reversing the direction of flow of the fluid such that the fluid is substantially removed from the fluid feed chamber.
A fluid sprayer system comprising:
- a reservoir containing at least one fluid to be sprayed;
- a fluid feed chamber for feeding a piezoelectric sprayer device;
- a flow inducer configured to induce the at least one fluid to flow from the reservoir to the fluid feed chamber during a spray cycle;
- and
- a controller configured to control the flow inducer to reverse a direction of flow of the fluid at an end portion of the spray cycle such that the fluid is substantially removed from the fluid feed chamber.

A method for dispensing a cosmetic product, comprising:
- actuating a piezoelectric sprayer including a fluid feed chamber;
- inducing, via a pump, a flow of a cosmetic product from at least one reservoir to the fluid feed chamber of the piezoelectric sprayer;
- reversing the direction of flow of the cosmetic product such that the cosmetic product is substantially removed from the fluid feed chamber;
- and
- terminating actuation of the piezoelectric sprayer.
