Abstract
The present invention relates to plural compartment assemblies in which materials are stored in at least two separate compartments until the compartments are opened for use. More particularly, the invention relates to a dispensing tube whereby the utilization of a novel insert, a conventional dispensing tube can be divided into separate and discrete compartments at a low cost. The resulting dispensing assembly provides for dispensing more than one material from the same tube and even more particularly co-dispense predetermined proportions of incompatible materials simultaneously and effectively.
