When ink is filled into an ink packincluding a bag partand an outlet part, firstly, air in the bagand outlet partis sucked by a suction pump Pprovided for an ink pouring apparatus. Further, by a first measuring pipe, ink supplied from a main tankis poured through the outlet partinto the bag part. Further, by a second measuring pipe, the ink poured into the bag partof the ink packis sucked and exhausted. Furthermore, the ink in the second measuring pipeis mixed into a mixing tankwith ink previously supplied to the mixing tankfrom the main tank. Next, the ink is supplied from the mixing tankto a third measuring pipe, and filled from the third measuring pipethrough the outlet partinto the bag part

Method of filling liquid into liquid containing member, liquid filling apparatus and method of inspecting liquid containing member

A method of refilling liquid into a cartridge according to the present invention is a method of liquid refilling, through which liquid is refilled into a used cartridge () in a liquid jet apparatus, comprising: a film removing process, in which an injection hole film () adhered around an air discharge opening (), which communicates with the interior of the used cartridge (), to seal the air discharge opening () is removed in order to make the air discharge opening () open; a liquid injecting process, in which liquid is injected into the used cartridge () through the air discharge opening () that has been made open in the injection hole film piercing process; and an injection hole film rewelding process, in which the film is rewelded using a surface other than an originally welded surface as a rewelded surface in order to seal again the air discharge opening (), through which the liquid is injected in the liquid injecting process.

Method of liquid filling of cartridge, liquid filling device, and cartridge

In a liquid container in which a liquid container case accommodates at least three liquid storing packs under a condition that the liquid storing pack partially overlaps the adjacent liquid storing pack, amounts of liquid stored in the respective liquid storing packs have a plurality of levels, and the liquid pack storing the most amount of the liquid is arranged at parts other than the center of arrangement.

Liquid container, liquid ejecting device, and method of checking arrangement of liquid storing packs

A method of manufacturing an ink cartridge for use in an ink jet recorder including positioning a container body having a bottom wall and an opening on a pallet such that the bottom wall faces upward, the container body including a porous member, a foam chamber for accommodating the porous member therein, and an ink supply port, having an inlet formed in the bottom surface of the foam chamber and an outlet; inserting packing into the ink supply port; sealing the ink supply port outlet; resetting the container body on the pallet by turning the container body upside down such that the opening faces upward; affixing a filter to the ink supply port inlet; inserting the porous member into the foam chamber; bonding a cover to the opening of the container body; injecting ink into the foam chamber; and sealing the cover.
