Container for use in erasing tool e.g. pen with correction liquid, has rotating device with stem body having head that advances slowly to support against liquid surface in cylinder when cap pushes body, to increase liquid pressure

摘要

The container has a rotation device (1), at a rear end of a liquid storing cylinder (2), having a stem body (11) and a cap (12). The body extends to the cap, such that the cap is at the rear end. The body has a stem head (111) adhered to an internal wall of the cylinder. The head advances slowly to support against a surface of a liquid (20) in the cylinder when the cap pushes the body, to increase the liquid pressure.
