[0079] Hereinafter, an embodiment in which the present invention is embodied will be described with reference to FIGS. 1 to 11 . 1 is a perspective view of an inkjet recording device (hereinafter referred to as a printer 11 ) as a liquid ejecting device according to the present embodiment; FIG. 2 is a perspective view of main parts of the printer 11 . FIG. 3 is an exploded perspective view of the ink cartridge 20 included in the printer 11 .

[0080] As shown in FIG. 1 , the printer 11 has a frame 12 roughly in the shape of a cube. Then, as shown in FIG. 2 , a rail shaft 14 , a carriage 15 , and a recording head 16 as a liquid ejection head are provided in the frame 12 .

[0081] The rail shaft 14 is formed into a rod shape, and is erected in the frame 12 . The bracket 15 is inserted through the rail shaft 14 and can move relative thereto, so that it can move back and forth relative thereto. Then, the carriage 15 is connected to a carriage motor (all not shown in the figure...

[0119] Next, a second embodiment of the present invention will be described with reference to FIG. 12 . In addition, since the second embodiment is only a structure in which the structure of the casing of the first embodiment is changed, description of the same parts will be omitted. In addition, FIG. 12 shows a cross section of the ink cartridge 40 in the longitudinal direction (longitudinal direction).

[0120] As shown in FIG. 12 , an ink cartridge 40 as a liquid container has a case 41 . The case 41 has a main body case 42 with an open upper surface, and a cover portion 43 fitted on the main body case 42 . Inside the main body case 42 is provided a frame 44 integrally formed with the main body case 42 and constituting a closed space for pressurizing the ink pack 24 , and the ink pack 24 is housed in the frame 44 . In addition, the storable volume V1, length L1, width W1, and height H1 of the bag portion 31 of the ink pack 24 are the same as those of the first embodiment,...

Abstract

In an ink pack 24 stored in an ink cartridge 20 of a printer, a first welded portion is formed by bonding both end portions of a sheet of film to each other. A tube-shaped bag portion 31 is formed by the first welded portion. One opening of the bag portion 31 is thermally welded in a state where a supply member 27 is inserted into the film, thereby forming a second welded portion 38. The other opening of the bag portion is sealed through the thermal adhesion, thereby forming a third welded portion 39. The ink volume capable of being stored in the bag portion 31 of the ink pack 24 is larger than the volume in a frame 26c for storing the ink pack 24.

Description

technical field [0001] The present invention relates to a liquid container. Background technique [0002] A liquid ejection device has a liquid container and a liquid ejection head, and ejects the liquid drawn from the liquid container from the liquid ejection head to a target opposite to the liquid ejection head. Such a liquid ejecting device includes, for example, an ink jet recording device. [0003] An inkjet recording device has a carriage, a recording head as a liquid ejection head mounted on the carriage, and an ink cartridge as a liquid container. Then, while moving the carriage relative to the target recording medium, ink is supplied from the ink cartridge to the recording head, and the ink is ejected from nozzles formed on the recording head to perform printing on the recording medium. [0004] In such an inkjet recording device, in order to reduce the load on the carriage and reduce the size and thickness of the device, the ink cartridge is not mounted on the ca...
