摘要:
The present invention is a tube squeezer designed to squeeze excess toothpaste, ointments, and similar materials trapped at the bottom of a collapsible tube dispenser. Two cylindrical rods positioned in parallel have notches to guide and hold two bands or O-rings at each end. The bands or O-rings provide pressure against the tube which is sandwiched between the two rods. Sliding the whole assembly up the length of the tube forces the residual contents to the top.
