ABSTRACT:
A disposable multi-cavity refill cartridge, for use with a reusable base and a reusable dispensing head for the simultaneous coextension of at least two flowable materials. The disposable refill cartridge has two hollow and separate parallel inner cylinders for each containing a flowable material. The inner cylinders have a first generally open top end which can be temporarily sealed until the refill cartridge is combined with a reusable dispensing head. The second or bottom end of the refill cylinders telescopically and slidingly accommodate parallel piston heads which are compressibly engageable with piston rods of a reusable base. The piston heads ride sealingly along the interior walls of the inner refill cylinders and when compressed by the piston rods, they force the flowable material to flow out of the refill cylinders and through the outlet means of the dispensing head. Once the flowable materials have been expended, the refill cartridge can be discarded and a new one can be used in conjunction with the reusable base and dispensing head.
