ABSTRACT:
Apparatus operable for dispensing toothpaste from an outlet opening at one end of a collapsible toothpaste containing tube is disclosed. The present apparatus includes a base member having a nozzle mounted adjacent a first end. The nozzle is adapted for cooperatively receiving and holding the one end of the collapsible toothpaste tube and has a passage therethrough for dispensing toothpaste from the tube. A pinch roller assembly is mounted to the base member for movement therealong between a location spaced from the nozzle and a location adjacent the nozzle, the pinch roller assembly including a pair of pinch rollers defining a space therebetween adapted for receiving the toothpaste tube in a generally collapsed condition. The outer surface of at least a first of the pinch rollers is adapted for engaging the tube so as to be capable of moving along the tube when rotated. The apparatus further includes a drive cable having one end attached to the first pinch roller for drivingly rotating it, the drive cable having an opposite end connected in rotatably driven communication with a gear motor or other rotatable power source. In operation, the rotatable power source is energizable for rotatably driving the drive cable and the connected pinch roller to move the pinch roller assembly along the toothpaste tube for collapsing a portion of the tube to pressurize the toothpaste therein and dispense the toothpaste through the nozzle.
