Abstract
A rigid piston-type multi-cavity dispensing container for simultaneous coextrusion of two or more flowable materials in a predetermined proportion, such as multi-component toothpaste and the like which, upon relative compression of the upper and lower body members, produces a single, banded, unmixed stream of material. The container has a unique outlet which is arranged to cause the outlet streams of material to flow towards each other. The outlet maintains the segregation of the different materials as they move simultaneously outward through the outlet.
