  • Patent number: 5248065
    Abstract: A device for squeezing out the contents of a tube, such as toothpaste. There is provided a flat, lower frame upon which is supported a squeezable tube whose contents are to be dispensed. Extending upwardly from the top, flat surface of the frame are two pairs of two guide-posts. The two pairs of guide-posts are aligned and are spaced apart along the length of the top surface of the frame. The two-guide posts of each pair are laterally spaced apart, whereby a tube may be inserted on the top surface and between the upstanding posts of the pairs of guide-posts. Mounted for manual, vertical movement along the two pairs of guide-posts are a pair of spaced-apart slide-blocks, one such slide-block for one such pair of guide-posts. Each slide-block has a pair of oppositely-disposed through-holes through which pass the two guide-posts of the respective pair. Both slide-blocks are used during the dispensing of the contents of a tube positioned on the top surface of the frame, between the guide-posts.
