A present invention provides an ink housing container inhibiting a resin used to form a layer located outside the innermost layer from flowing into a position other than a predetermined one. In an ink tank having an ink container and a cover member, the ink container is formed by a plurality of layers by means of molding. A flow-in preventing portion is formed at a cover member-side end of a side wall of an inner layer one of a plurality of layers forming the ink container. The flow-in preventing portion is formed so as to project from the cover member-side end.

A liquid container for containing liquid includes an optical path formation member for forming an optical path for guiding to an operating portion light received from an outside at a predetermined position of the liquid container, the optical path forming member constituting a part of the liquid container, wherein the operating portion is caused to emit light by the light guided by the optical path.

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.
摘要:
In a configuration to inform conditions of an ink tank such as an ink residual quantity by use of a light emitting portion such as a light emitting diode, a display in a position easily viewable to a user is achieved without requiring electric wiring that hinders user visibility and operability. A display section for displaying information by letting light out is separated from a light emitting portion, and a light guiding portion for achieving optical connection between both of the constituents is provided on an ink tank holder. In this way, it is possible to dispose the light emitting portion and the display section respectively in optimum locations, and to ensure freedom of disposing the display section in a position achieving fine user visibility.
