Title:
インクタンク
Document Type and Number:
Japanese Patent JP4731898
Kind Code:
B2
Abstract:
A package is formed including an ink tank in a bag. A cap is attached to an ink supply port of the ink tank. In the cap including an adsorption material made of zeolite, the adsorption material is arranged in a position in the cap where the adsorption material does not interfere with the ink tank when the cap is attached to the ink tank. By this arrangement, it is possible to adsorb ammonia gas issuing from the ink tank and hold down the amount of ammonia gas that reacts with electrodes of the substrate on the ink tank. Zeolite adsorbs and releases ammonia gas and does not adsorb ammonia gas limitlessly; therefore, it is possible to prevent notable changes in the composition of components of the ink stored.
