<p>A multi-cavity dispensing container is provided for the coextrusion of at least two flowable materials. The container includes a refill cartridge (2) and a reusable base (4). The cartridge contains a pair of separate parallel cylinders (16) within which are carried the flowable materials. At a lower end of each cylinder (16) is a piston head (26). The lower surface of the piston head (26) is configured as a hollow recess (38). The reusable base (4) is formed with a pair of separate parallel piston support posts (32). These posts (32) are characterized by a central hub (34) surrounded with at least two outwardly projecting arms (36). Tops of the posts (32) can readily engage within the recesses (28) of the piston heads (26). Consequently the refill cartridge (2) and reusable base (4) can be readily engaged and disengaged from one another.</p> |
