Patent ID: 7828176

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 in interchamber fluidic communication; a common wall between said chambers containing an aperture permitting interchamber fluidic communication and capable of being blocked to prevent said interchamber fluidic communications; a dispensing channel controlling fluid communication between said pump chamber and an exterior orifice for discharge of pressurized pump fluid; said pump chamber being sufficiently flexible to be reduced in volume by application of external finger pressure sufficient to expel pressurized pump fluid through said orifice and said pump chamber having sufficient resilient means to regain original volume absent said external pressure and refill said original volume with reservoir fluid drawn through unblocked said aperture; and, the pump action transferring said pump fluid characterized by said aperture being blocked and closed by a portion of exterior reservoir chamber wall surface applied directly to said aperture by sufficient purposeful said external finger pressure and opened absence said external finger pressure holding said reservoir wall in a blocking relationship with said aperture and permitting fluidic communication between chambers.
