ABSTRACT:
A dispenser for flowable materials such as creams, includes a pair of open ended containers nested telescopically with each other at their open ends, with the upper container having a dispensing orifice formed therein adjacent its upper end and containing a hollow dispensing channel communicating at one end with at least a portion of the orifice and having its other end located adjacent the open end of the upper container. A piston is received in the upper container for sliding movement with respect to the dispensing channel and has a hollow rod operatively connected to it which telescopically engages the dispensing channel. This hollow rod has a bottom end that engages the closed end of the lower container and also has an opening formed therein adjacent its bottom end to provide communication between the interior of the lower container and the hollow rod. A separator-seal disc is located in the lower container for movement relative to the hollow rod and is positioned to be engaged by the end of the upper container adjacent its open bottom. By this arrangement material contained in both the first and second containers will simultaneously be discharged from the dispensing opening in the upper container upon depression of the upper container into the second container.
