A disposable multi-cavity refill cartridge (100), for use with a reusable base (2) and a reusable dispensing head (1) for the simultaneous coextension of at least two flowable materials. The disposable refill cartridge or cartridges have at least one hollow and separate parallel inner cylinder (111, 112) for containing a flowable material. The inner cylinders have a first generally open top end (152) 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 (4) which are compressibly engageable with piston rods (8) of reusable base. The piston heads ride sealingly along the interior walls of the inner refill cylinders when compressed by the piston rods and they force the flowable material to flow out of the refill cylinders and through outlet means (17) of the dispensing head. Once the flowable materials have been expended, the refill cartridge or cartridges can be discarded and new ones can be used in conjunction with the reusable base and dispensing head. |
