  • Patent number: 6378732
    Abstract: A tube squeezing device comprises a rectangular housing having a longitudinal slot formed in its front wall. The housing is pivoted to a backing plate which includes a tube retaining base for receiving and clamping the neck of the tube. A slide is arranged to slide within the housing, with the first and second rollers being mounted to the carriage. Each roller is provided with a slide advancing face and a tube squeezing face which are substantially perpendicular to each other, with a serrated and curved tube gripping face extending therebetween. The slide advancing faces define a nip which is slightly wider than a squeezed portion of the tube, thereby allowing the slide to move to a position in which the gripping faces or each roller abut the tube shoulders at the commencement of the unsqueezed portion of tube. Upon downward actuation of a lever, the rollers counter-rotate towards one another so that material from an adjacent unsqueezed portion of the tube may be squeezed.
