US 4,050,612 A · Dispensing container

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.

Dependent claims

A dispenser for flowable materials comprising a first, open-topped container, a second open-bottomed container dimensioned to be telescopically received in said open topped container with its open bottom therein, said open-bottomed container having a dispensing orifice formed therein and containing a hollow dispensing channel communicating at one end with at least a portion of said orifice and having its other end located adjacent the open bottom of said second container;

a piston received in said second container for sliding movement therein with respect to said dispensing channel;
a hollow rod operatively connected to said piston and telescopically engaging and receiving said dispensing channel, said hollow rod having a bottom end engaging the bottom of said first container and having an opening therein providing communication between the interior of said first container, said hollow rod and said dispensing channel and a separator-seal member located in said first container for movement relative to said rod and in position to be engaged by the edge of said second container surrounding the open bottom thereof, whereby material contained in said first and second containers will be simultaneously discharged upon depression of the first container into the second container.

A dispenser for flowable materials comprising a first, generally cylindrical, open-topped container;

a second generally cylindrical open-bottomed container dimensioned to be telescopically received in said open-topped container with its open bottom therein;
said second container having first and second dispensing orifices formed therein;
a hollow dispensing tube in said second container communicating at one end with said first orifice and having its other end located adjacent the open bottom of said second container, said tube having a portion thereof extending generally axially of said second container;
a piston slidably received in said second container for sliding movement with respect to said dispensing tube for urging material in said second container out of said second orifice when the piston moves towards the top of the second container;
said piston including a hollow piston rod axially located in said first container and being open at both ends, said piston rod beig dimensioned to telescopically receive said dispensing tube through said piston and having an open bottom end engaging the bottom of said first container for providing communication between the interior of said first container and said dispensing tube;
and a separator-seal disc located in said first container in position to be engaged by the edge of the second container and having an aperture therein slidably receiving said piston rod;
whereby material contained in said second container between its top and said piston, and material contained in said first container between its bottom and said separator-seal disc will be simultaneously and respectively discharged through said first and second dispensing orifice upon depression of the first container into the second container.
