ABSTRACT:
An improved flexible wall dispensing tube is disclosed. The tube has a plurality of circumferential ridges along its length and a spherical plunger ball mounted inside near its sealed end. The outside of the tube is squeezed from the rear to push forward the plunger ball which then uniformly pushes the tube contents ahead of it while significantly preventing leakage back past the ball. As the plunger ball is pushed, or softly clicked, past the inside vertex of each groove formed between ribs, a stepwise uniform amount of tube contents is pushed out of the tube.
