Abstract
A planar, partition-forming insert member, when disposed in a tube, e.g., a toothpaste tube, divides the tube into two compartments for storage of two components which are to be prevented from reacting until the product is ready for use. A dual-compartment assembly contains the two separate compartments in which the two components are stored until the compartments are opened for use. The assembly contains a dispensing tube and the planar partition-forming insert member disposed in the tube, the insert member causing the tube to be divided into the two compartments. The assembly is capable of separately storing the components in the two compartments and simultaneously dispensing the components from the two compartments.
