Problems solved by technology

In addition, it is difficult to position and fix the bag container filled with liquid such as ink in the outer container without shaking.
[0013] (2) After the liquid (ink) in the bag container is used up, the injection needle can be inserted into the bag container from the opening of the outer container to replenish the liquid (ink), but the needle must be plugged with a special adhesive tape after the trace mouth
[0014] (3) Due to the dual structure of the bag container as the outer container and the inner container, the synthetic resin used increases correspondingly, the material cost increases, and at the same time, the weight increases
[0018] However, in the above-mentioned ink cartridge 301, the cylindrical ink discharge port 306 of the above-mentioned inner container 302 is used to protrude to the outside from the hole portion

Abstract

An ink cartridge that protects a cylindrical ink discharge port of an inner container that protrudes from the bottom of the outer container. The ink cartridge (1) has an inner container (2) for storing ink, an outer container (3) for storing the inner container (2), and a cylindrical ink discharge port (13) attached to the bottom of the outer container (3). ) cap (23). Under the bottom of the outer container (3), there is an outer periphery of the cap (23) fitted to the cylindrical ink discharge port (13) protruding from the ink discharge port (33) of the outer container (3) and aligned. Protective ribs (41). The reinforcing rib (41) has a cap release direction rotation preventing portion (42) that prevents the cap (23) from being released.

Description

technical field [0001] The present invention relates to an ink cartridge for an ink jet recording apparatus such as an ink jet printer that performs recording by directly ejecting ink from nozzles provided in a recording head on a recording medium such as recording paper. Background technique [0002] In an inkjet recording apparatus typified by a printer, ink is supplied to a recording head provided with a plurality of nozzles mounted on a carriage, and ink is directly ejected on a recording medium such as recording paper to perform recording. In addition, the supply of ink to the recording head is performed through an ink storage container (hereinafter referred to as an ink cartridge) commonly called a cartridge, which is detachable and replaceable from the recording head. The above-mentioned ink cartridges are known to include a hard type ink cartridge and a soft type ink cartridge. [0003] like Figure 21 , Figure 22 As shown, the rigid ink cartridge 101 is composed ...
