Patent ID: 8556128

Claim:
A fluid dispenser, comprising: a reservoir chamber and a pump chamber, both chambers having at least one flexible wall surface and containing a fluid; said pump chamber being a flexible, resistive predetermined shape capable of volumetric reduction by deforming under sufficient finger pressure so as to pressurize pump fluid contained within; a channel with at least one flexible wall positioned between said reservoir wall and said pump chamber wall and providing fluidic passage between said chambers; said channel being flexible, resistively deformable of predetermined shape, a portion capable of being compressed by sufficient finger pressure so said channel wall blocks fluid passage; said channel having resilient deformable properties characterized as less resistive than said pump chamber resistive properties so as to cause said channel walls to respond first to deforming said finger pressure to block said channel before developing significant pressurizing of said pump chamber fluid; said channel and said pump chamber being so arrayed one to the other in a layered fashion so that application of direct linear finger pressure deforms each together to compress said portion of said channel by said direct finger pressure sufficient to block fluid passage thru said channel and to pressurize pump chamber fluid blocked from moving thru said channel; a dispensing channel with a one-way valve providing exiting fluidic communication between said pump chamber and an orifice for discharging said pressurized pump chamber fluid; and, whereby said pump chamber develops sufficient fluidic pressure from said finger pressure to discharge said pressurized channel blocked pump chamber fluid thru said dispensing channel to exit through said orifice and absent said finger pressure said resilient channel unblocks and said resilient pump chamber reforms undeformed shape and thereby draws in said fluid from said reservoir chamber thru said unblocked channel completing a pump cycle.
