A vented output device for uniformly mixed liquid comprising a barrel defining a reservoir for containing the uniformly mixed liquid, and at least one vent channel extending from a first vent opening in fluid flow communication with an exterior of the device and second vent opening in fluid flow communication with the reservoir. A binary ink storage assembly includes multiple glass ampoules arranged in pairs, which are placed inside the barrel in parallel. The invention provides a reliable, simple and low-cost output device for solving the problem of not allowing the liquid to be uniformly mixed and output when a chemiluminescent marker or pen is activated.

An ink storage member for writing implements may reduce environmental impact by replacing the conventional aluminum with silica for the intermediate layer between the inner and the outer layer, both of which use paper as a base material, in a paper refill for writing implements. An ink storage member for writing implements may have at least three layers, including an inner layer of a paper base material, an intermediate layer formed on an outer surface of the inner layer, and an outer layer of the paper base material formed on an outer surface of the intermediate layer. The intermediate layer may have at least one layer selected from an aluminum oxide film layer, a silica film layer formed from a low molecular weight silane, and a silica film layer formed from a polysilazane.

Provided is a liquid storage member for coating tools that uses a paper material, having an ink follower filled at the rear end part of a liquid storage tube made of paper, and preventing leakage and backflow of the ink follower. The liquid storage member for coating tools according to the present invention comprises: a liquid storage tubes using a paper base material; and an ink follower having a yield stress of 16 Pa or more, and preferably, a phase angle of 35 or more when a shear strain amplitude at 25 C. and 1 Hz is 0 to 30%. The liquid storage member for coating tools follower is suitable as a paper refill for a writing tool.
