ABSTRACT:
A dispenser for tubes of fluent materials, such as toothpaste, wherein the tube is placed between two wings which are progressively moved towards each other to squeeze the tube and dispense its contents. The wings are mounted at their ends which are remote from the open end of the tube and are movable towards each other by two guides mounted on a carriage which is movable from the mounted ends of the wings towards the open end of the tube. As the carriage moves from the mounted ends of the wings, where the wings are close to each other, towards their other ends, where the wings are initially further apart, the wings are forced together to apply a squeezing force to the tube. The guides are moved by a ratchet system including a reciprocable rack and a ratchet tooth provided on the carriage. Movement of a dispenser operating lever moves the rack in one direction to move the carriage. The ratchet system includes a fixed rack to prevent the carriage from moving in the wrong direction. The operating lever is preferably situated so that an article such, for example, as a toothbrush, pressed against it will have the fluid material, e.g., toothpaste, dispensed directly onto it.
