ABSTRACT:
A dispenser apparatus for dispensing a portion of the contents from compressible tubular containers such as those used for toothpaste includes a plastic housing member having one portion designed for the receipt of an air pressure pump and associated linkage, and a second outward portion in communication with the air pressure pump but otherwise sealed, and a front panel portion hinged to the remainder of the housing for selectively opening and closing the second outward portion so as to define a sealed chamber. A tubular container such as a toothpaste tube is placed in the sealed chamber and the side walls of the tube are compressed by the introduction of air pressure into the sealed chamber. The bottom surface or wall of the housing includes an internally threaded outlet which is rigidly secured to the housing and which is suitably designed to receive the threaded end of the tubular container such that when one tube is empty, it may be unscrewed and a new tube screwed into this outlet. A mechanical linkage connects the air pressure pump to an exterior pushbutton control and the connecting linkage also cooperates with a pulley arrangement to selectively open and close a slide valve disposed over the outlet such that as the air pressure pump is activated the valve is opened and when the air pressure pump is deactivated, the valve closes.
