ABSTRACT:
An automatic toothpaste dispenser employs a roller-type squeeze device that is driven along the toothpaste tube simultaneously with the opening of a gate that permits the toothpaste to flow. After the desired amount of toothpaste has been dispensed, the roller is automatically retracted and the gate is simultaneously closed. However, the retraction of the gate only continues until the gate is closed, which results in a ratchet-like effect, the roller being retracted a smaller distance than that by which it is advanced.
