ABSTRACT:
A container for fluid products having telescoping parts and operable by outside manual pressure is provided. The container assembly includes a base cup, a plunger cup telescopingly received in the base cup and relatively slidable therein, a nozzle in direct communication with each of the cups, and a pair of slidable pistons, one located in the base cup and relatively fixed with respect to the plunger cup and the other located in the plunger cup relatively fixed with respect to the base cup, for forcing product from the cups to the nozzle upon telescoping movement of the cups together. An air intake is provided to admit air from the surrounding atmosphere between the cups into an interior space adajcent to the slidable pistons to avoid a vacuum in the container and prevent seepage of the products from the cups. A set of locking threads is formed on each of the cups for locking the cups in an extended relationship to prevent undesired telescoping movement in the filling and handling of the container. When disengaged, the threads slidably engage the side walls of the cups to stabilize the telescoping movement of the cups. A telescoping transfer tube assembly is provided to supply product from the base cup directly to the nozzle and to further stabilize the telescoping movement of the cups.
