Abstract
A condiment dispenser is provided having a length of resilient elastic tubing with an upper tube section and a lower tube section. An arm is pivotally mounted adjacent the tubing and moveable through dispensing and return strokes. The arm has an upper arm portion adjacent the upper tube section and a lower arm portion adjacent the lower tube section. During the dispensing stroke, the upper arm portion moves to compress the upper tube section against a wall on the opposite side of the tubing while the lower arm position retracts from the lower tube section to cause the condiment to be dispensed. The return stroke is caused by the return of the compressed upper tube section to a less compressed section, causing the lower arm section to compress and close the tubing at the lower tube section against the wall.
