Abstract
A manually portable spray tank includes a plug-like adapter mounted in the filler opening or mouth of the tank to receive and hold a pressurized can or canister containing a liquid propellant. The adapter includes a depending, elongated heat exchanger tube or trap which is closed at its lower end and which extends almost to the bottom of the tank for direct heat exchange contact with the liquid contained in the tank. Liquid propellant under pressure flows from the supply can into the heat exchanger tube or trap where it is vaporized by heat from the spray liquid in the tank. The vaporized propellant then passes under relatively high pressure outwardly through a comparatively small opening in the upper end of the heat exchanger tube into the ullage of the tank to pressurize the column of spray liquid in the tank and thereby insure its forcible discharge from the outlet of the spray tank.
