A dispenser for collapsible tubes which includes an elongate flexible plastic support for the collapsible tube having a flange on its lower end with an aperture through which the dispensing end of the tube extends. The flexible member has rows of generally rectangular apertures formed adjacent the opposite side edges thereof to serve as racks. A pair of tube squeezing rollers are journalled in a frame and are adapted to engage over the flexible member with the tube mounted thereon. One of the tube squeezing rollers has sprocket gears on each end thereof for engaging in the rack of the flexible member with the other roller having an annular groove at each end thereof into which the teeth of the first roller extend. A key on one end of the first roller is provided for rotating the rollers to move the frame downwardly on the flexible member with the rollers squeezing the front and rear of the flexible tube dispensing the contents therefrom.
