Patent ID: 6991136

Claim:
A device for removable attachment to a fluid container of the type including a threaded neck surrounding a discharge opening in fluid communication with an interior chamber of the fluid container, the device comprising: a rigid handle portion; a manually operated pump mechanism coupled to the handle portion, the pump mechanism operative to introduce a charge of pressurized air into the interior of the fluid container, wherein the pump mechanism includes a squeeze bulb; an air delivery conduit providing fluid communication between the pump mechanism and the interior of the fluid container; and a head portion including: threads for threaded engagement with the threaded neck of the fluid container thereby providing a substantially airtight seal between the device and the discharge opening of the fluid container to contain the charge of pressurized air and the fluid within the interior chamber of the fluid container; and a valve spout operable between a closed position to contain the fluid and the charge of pressurized air within the interior of the fluid container, and an open position to permit dispensing of the fluid through the discharge opening and from the valve spout; wherein rotation of the squeeze bulb relative to the handle portion is prevented, wherein the pump mechanism comprises: a central body surrounding a compressible interior air chamber and operable between a normally relaxed full state and a compressed state; a first end portion; a second end portion; a one-directional intake valve for drawing air into the interior air chamber upon the central body returning to the relaxed state from the compressed state; and a one-directional exhaust valve on the second end portion for directing air outwardly from the interior air chamber and to the air delivery conduit upon the central body being compressed from the relaxed state to the compressed state, wherein rotation of the squeeze bulb relative to the handle portion is prevented by holding the second end portion in a substantially fixed position relative to the handle portion, and wherein the second end of the squeeze bulb is keyed, wherein the handle portion includes a receptacle adapted for keyed receipt of the second end portion of the squeeze bulb to prevent rotation of the squeeze bulb relative to the handle portion upon operation of the manually operated pump mechanism between the normally relaxed full state and the compressed state.
