ABSTRACT:
BACKGROUND AND OBJECTS OF THE INVENTION
The present invention is generally related to the dispenser arts and, in particular, to a system and method for dispensing granular materials such as laxatives.
As is known in the art, laxatives are typically sold in cylindrical containers and so it is often difficult to dispense a certain desired amount of the laxative material.
Dispenser units are known in the art but such are typically difficult to use accurately and costly to manufacture for widespread commercial appeal and use.
Accordingly, it is an object of the present invention to demonstrate a novel dispensing unit and method which may be easily used to dispense a desired amount of material.
It is also an object of the invention to set forth a dispensing unit which may be economically mass-produced for widespread commercial appeal.
It is a still further object of the invention to illustrate a dispensing unit which may be easily assembled and disassembled to facilitate cleaning of the unit when desired.
It is also an object of the invention to show a dispensing unit of high'structural integrity for long-life of the overall unit.
These and other objects of the present invention will be apparent to those of skill in the art from the description which follows.
PRIOR ART PATENTS AND DESIGNS
U.S. Pat. Nos. 5,588,563 and 4,429,815 illustrate the prior art designs for powdered and granular materials.
They illustrate systems which are rather difficult to use and apply in practice. Prior art systems are also costly to manufacture and are typically not of a durable construction.
The advantageous structure and method of the present invention is thus believed to be clearly patentable over all known prior art designs.
SUMMARY OF THE INVENTION
The invention comprises an outer housing which is adapted to fit over the end of a laxative container.
The housing has a number of struts and spars to ADD structural integrity to the overall unit.
A hollowed-out shaft is adapted to fit rotatably within the housing.
In practice of the inventive method, the shaft is turned to a desired position so that the hollowed-out portion is filled. Subsequently the shaft is turned to a dispensing position by the user.
In this manner, an exact desired dosage of the material may be easily dispensed.
