Patent ID: 8550309

Claim:
A molded fluid pump dispenser operable to be connected to a non-pressurized fluid container, said molded fluid pump dispenser comprising: a base; a pump chamber floor connected to said base and being operable to pivot from a connected molded condition into flush engagement with said base wherein, a fluid inlet port extends through said pump chamber floor, and an inlet check valve is pivotally connected to said chamber floor and operably covers said fluid inlet port to permit one way flow of fluid from a container of fluid through said inlet check valve; and a compressible pump chamber spout having, a rigid spine connected to said base by a living hinge, a relatively thin wall section connected to said spine and circumferentially jointed to said base, said thin wall section in cooperation with said rigid spine forming a pump chamber spout, and an outlet check valve molded internally into approximately a distal end of said pump chamber spout wherein said chamber floor having an inlet check valve, said pump chamber spout having a rigid spine and a thin wall pump chamber section and said outlet check valve forming a pump chamber fluid spout, wherein upon pivoting of said pump chamber fluid spout by said rigid spine about said living hinge said pump chamber fluid spout collapses said relatively thin wall section between said pump chamber floor and said spine to expel fluid within the interior of said pump chamber fluid spout past said outlet check valve and out of said pump chamber fluid spout and then returning said rigid spine to a generally upright posture with a generally empty pump chamber fluid spout resulting in an interior pump chamber fluid spout pressure being less than ambient pressure which induces fluid at approximately ambient pressure within a container to push through said inlet check valve to refill said pump chamber fluid spout with fluid to be dispensed.
