The present invention provides an ink filling tool including: an ink tank having an internal space configured to store a liquid ink; and a cylindrical nozzle having an inner hole communicating with the internal space of the ink tank, the nozzle being insertable into the through hole. The nozzle is configured to be capable of pressing the valve mechanism which is present inside a pen in a state of being inserted into the through hole, and the nozzle has an ink circulating part configured to communicate the inner hole with an outside in a direction orthogonal to the axis of the nozzle.

An automatic cover-opening device has a body, at least one cover panel and a recoil mechanism. The body has an insertion hole defined in the body. The at least one cover panel is mounted on the body and moveably closes the insertion hole. Each one of the at least one cover panel has a guiding segment having at least one guiding edge inclined relative to an axis of the insertion hole to guide an axial force along the axis of the insertion hole to a lateral direction non-parallel with the axis, so as to generate a lateral component force for opening the at least one cover panel. The recoil mechanism is disposed on the body to push the at least one cover panel to a closed position for closing the insertion hole. With such an arrangement, an automatic cover-opening device that can be applied for insertion of a rod-like object is provided.

Disclosed are a knock type direct liquid pen refill assembly and a writing pen. The pen refill assembly comprises an ink cylinder assembly (100), a pen tip (200) and an elastic member (300). An ink guide core (150) is provided in the ink cylinder assembly. The pen tip (200) is arranged at one end of the ink cylinder assembly (100). An ink duct (210) is formed inside and passes through the pen tip (200). A ball member (230) is provided at an ink outlet end of the ink duct (210). The ink guide core (150) partially passes through the ink duct (210), and one end of the ink guide core (150) is abutted against the ball member (230). The elastic member (300) is sleeved at the periphery of the ink guide core (150) and positioned inside the ink duct (210). The elastic member is abutted against the ball member to exert a force, such that the ball member is closely attached to an inner wall of the ink outlet end, the ball member forms sealed contact with the inner wall of the ink outlet, and ink volatilization and leakage are avoided.

A device for removing a liquid from a container having a depressible valve is provided. The device may include a reservoir for holding the liquid removed from the container. A conduit of the device may include a first end and a second end. The first end may be fluidly coupled to the reservoir while the second end may be fluidly coupled to the container. Depressing the conduit may actuate the depressible valve of the container to provide fluid communication of the liquid from the container, through the conduit, and into the reservoir.
