<p>A multi-cavity dispensing refill cartridge is provided, to be used with a reusable base. The refill cartridge has two hollow, separate parallel cylinders for containing flowable material. The cylinders have a first generally closed end and a second end which accommodates piston heads and outlet means. The piston heads are compressably engageable with piston rods of the reusable base. Relative compression of the piston heads and cylinders cause flowable material to flow toward the first end of the cylinders and out the outlet means. The outlet means include means for causing the flowable materials to flow toward each other at the outlet opening. The refill cartridge is provides with means for selectively, engaging the reusable base.</p> |
