Abstract
A container of paint or other liquid is seated within a pressurized vessel. Both the vessel and the paint container are designed with a special orientation. This assures that only the specially-designed paint container will be received within the pressurized vessel, and discourages the use of a standard commercially-available can of paint. The top of the paint container is closed by a diaphragm. The diaphragm has an annular recess normally closed by a removable plug. When the plug is removed, a delivery pipe sealingly carried by the vessel lid extends through the diaphragm and is received vertically within the paint container. A small opening in the diaphragm assures that the pressure internally and externally of the paint container will be substantially equalized. The delivery pipe is connected to a flexible feed tube, and the end of the feed tube is connected to a hand-held applicator. The applicator carries an on/off switch for interrupting the flow of paint to the applicator. The applicator also carries a regulator for varying the amount of paint flowing through the applicator to the work surface. A replaceable gas cartridge is housed on the lid of the vessel, and pressurizes t…
