Abstract:
1. 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 handle portion; an air delivery conduit; a manually operated pump mechanism including: a coupling mechanism which secures the pump mechanism to the handle and is structured and disposed to prevent rotation of the pump and obstruction of airflow of the air delivery conduit; and a container engaging portion with threads for threaded engagement with the threaded neck of the fluid container 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, the container engaging portion including: the air delivery conduit providing fluid communication between the exhaust valve of the pump mechanism and the second connection point of the container-engaging portion for directing airflow from the pump mechanism to the fluid container; and a trigger lever positioned above the container engaging portion comprising: a fluid discharge nozzle comprising: a housing comprising a head portion integral with the rigid handle portion; and a pinch valve manually operated by the trigger lever and is 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 fluid and air flow, the pinch valve permitting fluid from the fluid container to pass through the fluid discharge nozzle when not in a closed position, including: a fluid conduit connected to the third connection point of the container engaging portion for positioning in the interior of the fluid container to draw out fluid and air from the fluid container; and wherein only one human hand is required to simultaneously hold the device, operate the pump mechanism, operate the valve, and aim the fluid discharge opening.
