Abstract

A tube squeezer is disclosed wherein a lower end portion of a tube is wound on a winding shaft so as to squeeze out the contents of the tube. The slit extends along an axis of the inner cylinder. An outer cylinder is rotatably fitted on an outer periphery of the inner cylinder. The outer cylinder has an open portion for receiving the closed end portion of the tube, and the open portion extends along an axis of the outer cylinder. A disc-shaped plate is fixedly mounted on one end of said inner cylinder in coaxial relation thereto. The disc-shaped plate has a projection-and-groove portion formed at its outer periphery. The projection-and-groove portion has alternate projections and grooves arranged radially. A lock lever is supported at one end on an outer periphery of the outer cylinder. The lock lever is engageable at the other end thereof with the projection-and-groove portion.
