  • Patent number: 4508242
    Abstract: The toothpaste dispensing apparatus of my invention comprises an enclosure which houses multiple separate tube holders for holding the tubes of paste. It, also, contains a reversible motor connected by a worm screw to a holder containing a pair of movable rollers for dispensing tooth paste, shaving cream, etc. from any of its multiple positions. The paste is discharged at the bottom of the inner tube holder by a squeezing pressure exerted upon the tube by the pair of rollers which moves downward over the inner tube holder. This device is equipped with a switch for automatically reversing the downward direction of the rollers when the contents of the tube have been exhausted. A most unique feature is the provision for housing several tubes and the selector knob, which allows the operator to choose either one of the several tubes on which to operate without having to dismantle or load or unload the device.
