Abstract
Abstract A squeezeable container in the form of a multiple compartment tube having a resilient bellows divider. One end of the bellows divider is secured to the neck and the other is crimped into the closed opposite end. The bellows have side pieces which lie flush against the inner side walls of the container so that two separate compartments are formed by the divider with the divider being deformable so as to permit variable amounts of material to be deposited in the several compartments.
