ABSTRACT:
The present invention is a tube press designed to squeeze excess toothpaste, ointments, and similar materials trapped at the bottom of a collapsible tube dispenser. Two rods having oblongated cross-sections are positioned in parallel and have notches to guide and hold two bands or O-rings at each end. The rods have preferred cross-sections of ellipses or football shapes. A tube-receiving slot is formed by gradual slopes towards a nip. The bands or O-rings provide pressure against the tube which is sandwiched between the two rods within the nip. Sliding the whole assembly up the length of the tube forces the residual contents to the top.
