ABSTRACT:
A refillable pressure spray container comprises a container having a filling and dispensing nozzle extending outwardly from a cap secured thereon, the nozzle being received in a quick disconnect coupling attached to a motor-driven pump. The quick disconnect coupling has a valve actuating member to raise a valve plunger in the nozzle when inserted into the coupling to establish communication between the pump and the interior of the container. The motor pumps air or gas under pressure into the container. At a predetermined container pressure, a relief valve deactivates the pump. When the container nozzle is removed from the coupling, the plunger closes communication between the container and the pump to pressure seal the contents within the container. A conventional spray nozzle is attached to the plunger for using the refillable container as a conventional aerosol container.
