ABSTRACT:
A cleaning system is disclosed for pumping compressed air and cleaning solvent to the injection cartridge of a foam-in-place packaging system. The cleaning system comprises a solvent tank for containing a stock supply of solvent; a source of compressed air; and an air-activated submersible solvent pump in air flow communication with the compressed air source. The system also includes an injection cartridge of a foam-in-place packaging system in liquid communication with the solvent pump; and a regulator in air flow communication with the compressed air source, the pump, and the injection cartridge. The regulator distributes compressed air to operate the pump and to travel with solvent to the injection cartridge to provide a cleaning mixture of solvent and air to the cartridge.
