Abstract
A collapsible dispensing system for viscous fluids which should not be mixed until the time of application. The system comprises a cartridge and a container which fits into the cartridge. The cartridge is designed to fit into conventional caulking guns. The cartridge has a forward end cap having a central circular orifice and a rear thrust wall. The container fits into the cartridge and is made up of a plurality of collapsible chambers which hold the viscous fluids. The chambers may take the form of closed bags or accordion cylinders. At the front end of each chamber is a forward end piece. The forward end pieces fit snugly together and form a circular periphery. The forward end piece contains a neck which fits through the forward end cap and attaches to a mixing nozzle. Chambers having predetermined ratios of ingredients may be used in this system.
