Abstract

A dispenser is disclosed herein having a paste container removably mounted in a stationary base with a dispensing nozzle for discharging paste therethrough. In one version, the paste container is pressurized by use of a removable air pump while in another version, a mechanical pump extracts paste into and through the nozzle. In either version, a brush-operated lever actuates a mechanism coupled to the nozzle for selectively releasing the pressurized paste.

Claims

1. A toothpaste dispenser operated by one hand comprising:

a toothpaste tube holding a quantity of paste;

a stationary support retaining said tube in a fixed position;

said support having a fixture outwardly projecting from said support having a first nozzle in communication with said tube;

said fixture having a primary chamber in communication at one end with said paste held in said toothpaste tube and terminating in an interior wall carrying said first nozzle at said chamber'"'"'s other end,

a movable element slidably carried on said fixture having an exterior wall carrying a second nozzle coaxially disposed with respect to said first nozzle;

an intermediate chamber provided in said movable element defined between said fixture interior wall and said exterior wall for receiving paste from said first nozzle preparatory for dispensing from said second nozzle;

spring means compressed between said stationary support fixture and said movable element normally biasing said element away from said fixture;

flexible sealing means operable about each of said nozzles to release paste into said intermediate chamber and exteriorly of said second nozzle respectively in response to linear movement of said movable element;

said movable element having two positions defined as a first position compressing said spring means to load paste into said intermediate chamber and a second position expanded by said spring means to expel paste from said intermediate chamber exteriorly of and via said second nozzle;

a deformable adaptor composed of pliable material intercoupling said tube with said stationary support; and

said firs position of said element creates a vacuum as it moves into its second position whereby paste is withdrawn via said fist nozzle past said sealing means to fill said intermediate chamber.

2. The invention as defined in claim 1 including:

manually operated lever means pivotally carried on said fixture and in engagement with said movable element to move said movable element into said first position.

3. The invention as defined in claim 2 wherein:

said lever means includes a hook in contact with said movable element and an extended arm having a terminating and adjacent to and in spaced relationship to said second nozzle whereby said movable element is responsive to pivot movement of said lever means when said arm terminating end is manually operated.
