ABSTRACT:
This invention provides a simplified device for dispensing paste materials from collapsible tube packages, such as the familiar toothpaste tube. A roller, actuated by an electric motor driven lead screw, compresses a tube within a cabinet to expell a desired quantity of the paste materials. A dispensing adapter provides for use of the invention with any common size of tube dispensing nipple and an adapter nozzle closure also serves as a motor switch actuation element.
