Problems solved by technology

[0003] In such a container, there is a problem that the liquid tends to remain in a part of the liquid absorber far from the liquid supply part due to the capillary force of the liquid absorber.
However, if such a filter is installed in the container, the inventors of the present application have found the following problem: for example, when a shock is applied to the container due to dropping or the like, the air existing on the liquid absorber side is easily filtered. The container moves to the side of the liquid supply part, and as a result, there is a possibility of poor discharge of the liquid.
[0004] In addition, the inventors of the present application have found a problem that when such a filter is installed in a container, the air existing between the filter and the liquid supply part expands when the air temperature rises, and the existing liquid is removed from the container. Possibility of leakage due to extrusion of the liquid supply part

[0045] A1. The structure of the liquid injection system:

[0046] figure 1 It is a perspective view showing the structure of the liquid ejection system 100 . exist figure 1 The X-axis, Y-axis, and Z-axis which are orthogonal to each other are drawn in . figure 1 The X-axis, Y-axis, and Z-axis of the graph correspond to the X-axis, Y-axis, and Z-axis of other graphs. In the diagrams shown thereafter, the X-axis, Y-axis, and Z-axis are also indicated as necessary. Let the direction along the X axis be the X direction, let the direction along the Y axis be the Y direction, and let the direction along the Z axis be the Z direction. In addition, let one direction of the X direction be +X direction, and let the other direction of the X direction be -X direction. Moreover, let one direction of a Y direction be a +Y direction, and let the other direction be a -Y direction. In addition, one of the Z directions is referred to as +Z direction, and the other is referred to as −Z dir...

[0136] Figure 22 is a cross-sectional view of a container 20b in the second embodiment. Figure 23 Yes Figure 22 A perspective view of container 20b is shown. In the above-mentioned first embodiment, the length of the filter 210 provided in the container 20 is 50% or more of the length of the liquid absorber 299 along the Y direction. On the other hand, in this embodiment, filter 210b is smaller than 50% of the length of liquid absorber 299 . Furthermore, the shape of the bubble trap chamber 212b is substantially rectangular parallelepiped, and the liquid guide path 231b is formed on the inner surface of the bubble trap chamber 212b in the +Y direction and the −Y direction so as to extend in the vertical direction. According to such a second embodiment as well, the ink in the bubble trap chamber 212b can be smoothly flowed to the liquid supply unit 280 .

no. 3 approach

[0138] Figure 24 is a cross-sectional view of a container 20c in the third embodiment. Figure 25 Yes Figure 24 A perspective view of container 20c is shown. In the second embodiment described above, the length of the filter 210b is smaller than 50% of the length of the liquid absorber 299 along the Y direction. On the other hand, in this embodiment, the length of the filter 210c is 50% or more of the length of the liquid absorber 299 similarly to 1st Embodiment. However, in this embodiment, unlike the first embodiment, the bottom surface 213c of the bubble trap chamber 212c is not inclined toward the liquid supply part 280 but is horizontal, and falls vertically in the vicinity of the liquid supply part 280 . Furthermore, in the present embodiment, the liquid guide path 231c is formed horizontally along the bottom surface 213c of the bubble trap chamber 212c, and descends vertically near the bubble trap chamber 212c. Also according to such third embodiment, the ink in t...

Abstract

The invention provides a cartridge. The cartridge includes a liquid supply portion configured to receive a liquid supply needle; a first chamber provided with a liquid absorber, a second chamber not provided with the liquid absorber and provided with the liquid supply portion; and a filter provided between the first chamber and the second chamber. A length of the filter in a longitudinal directionof the filter is longer than half a length of the liquid absorber in the longitudinal direction.

Description

technical field [0001] The present invention relates to a container. Background technique [0002] As a container used by a liquid ejecting device such as an inkjet printer, a container in which a liquid absorbing body for holding a liquid is disposed in a liquid containing chamber in the container is known (refer to JP-A-2000-33715, JP-A-4 -173343, JP-A-2006-76313, and JP-A-2006-76314). As the liquid absorber, for example, a porous body and a fibrous body are used. The liquid held by the liquid absorber is sucked by the liquid ejection device from a liquid supply unit provided on the bottom surface of the container or the like, and supplied to the liquid ejection device. [0003] Such a container has a problem that liquid tends to remain in a portion of the liquid absorber far from the liquid supply part due to the capillary force of the liquid absorber. Therefore, the inventors of the present application conducted research on a case in which a large filter is arranged b...
