Abstract
A tool for squeezing out a high-viscosity liquid from a flexible plastic tube container includes a spool having a slot in which the bottom of the tube container is received and locked, and a container holder having a pair of opposed bearing portions frictionally and rotatably supporting thereon a body of the spool, and a pair of opposed engagement portions engageable with a body of the tube container as the tube container is wound on the spool body from the bottom thereof. When a rotational force or torque on the spool is released, the spool is urged to rotate in the reverse direction by a resilient force stored in a portion of the flexible plastic tube container wound on the spool body. However, partly due to a friction acting between the spool body and the bearing portions, and partly due to the engagement between one of the engagement portions and the tube container, the spool is held immovable relative to the container holder against the resilient force of the tube container.
