A tube dispenser utilizes a ratchet actuated pusher for squeezing the contents from a tube. In a first embodiment, a tube is supported on a support plate with a nozzle of the tube extending through an aperture formed in an end wall connected to the support plate. A handle, mounted on an opposite end wall, has an attached ratchet actuation lever. A toothed rod extends through an aperture in the end wall adjacent the handle. A pair of frame rods extend betwen the end walls. By squeezing the ratchet actuation lever, the pusher is caused to advance along the support plate, squeezing the tube walls between the pusher and the support plate. Three different configurations of the pusher are disclosed. The pusher may be formed as a cylindrical bar, a right angle channel, or as a plurality of rotatable rollers. In a second embodiment, the tube is supported within a receptacle, with a nozzle of the tube extending through an aperture in an end wall of the receptacle. A plurality of rotatable rollers are mounted in a triangular configuration for sliding movement along a partition floor of the receptacle. A squeezing slot is formed between the rollers. A toothed bar in conjunction with a ratchet lever are utilized to advance the rollers along the partition floor of the receptacle, thus dispensing the tube contents.
