The height dimension h1 of the gap formed between the cover part 15b corresponds to the thickness dimension t1 of the locking part 41 in the screwing direction (vertical direction) of the lid 3 and the cylindrical part 16. That is, the height dimension h1 of the gap formed between the lid 3 and the bottom surface 15b of the step portion 15 is substantially equal to the thickness dimension t1 of the locking portion 41. Therefore, it is possible to prevent a large load from being applied to the locking portion 41 of the holding member 7 positioned between the lid 3 and the ink container 2 when the lid 3 is fastened to the cylindrical portion 16. As a result, it is possible to prevent the locking portion 41 from being damaged, and thus it is possible to prevent the locking portion 41 from dropping from the ink container 2 due to breakage.

(Function and effect)
According to this example, the storage device 5 is not directly held by the ink container 2, but the storage device 5 is held by the holding member 7, and the holding member 7 is locked to the ink container 2. Accordingly, the storage device 5 can be supported by the commercially available ink container 2 without providing the ink container 2 with a special shape. Therefore, it is easy to procure the ink container 2, and the procurement cost can be suppressed.

  In addition, the holding member 7 is locked to the ink container 2 and the lid 3 by positioning a part of the holding member 7 between the ink container 2 and the lid 3. If it is removed from the ink container 2, the holding member 7 can be easily removed from the ink container 2 and the lid 3. Accordingly, the storage device 5 of the ink container 2 can be easily taken out.

  Further, since the holding portion 42 of the holding member 7 is provided with the window 44 facing the lid 3 side, whether or not the storage device 5 is held by the holding member 7 when the lid 3 is attached or detached. Can be easily confirmed. As a result, forgetting to hold the storage device 5 in the holding member 7 can be prevented. In addition, forgetting to remove the storage device 5 from the holding member 7 can be prevented.

  Further, in this example, the holding member 7 holds the storage device 5 at a position removed from between the ink container 2 and the lid 3. Therefore, it is possible to avoid the storage device 5 held by the holding member 7 from being sandwiched between the ink container 2 and the lid 3 and being damaged. Further, since the holding member 7 holds the storage device 5 at a position deviated from the imaginary line L connecting the grip portion 18 and the ink inlet / outlet 2a, the ink in the ink container 2 flows out through the ink inlet / outlet 2a. Even when the holding member 7 is not removed from the ink container 2, it is possible to prevent or suppress the storage device 5 from getting wet by the ink.

  Furthermore, in this example, the holding member 7 is housed inside the step portion 15, and the holding member 7 does not protrude outward from the step portion 15. Further, the holding member 7 is prevented from rotating around the cylindrical portion 16 and protruding outside the step portion 15. Accordingly, it is possible to prevent or suppress the storage device 5 from being damaged when the ink container 1 is transported. Further, when arranging and stacking a plurality of ink storage containers 1, the holding member 7 attached to one ink storage container 1 does not interfere with other ink storage containers 1. Work is easy.

(Modification)
In the above example, the thickness dimension t1 of the locking portion 41 of the holding member 7 is larger than the pitch p1 of the male screw 17 of the ink container 2, but the thickness dimension t1 of the locking portion 41 of the holding member 7 is equal to the male dimension. It may be shorter than the pitch p1 of the screws 17. In this case, since the locking portion 41 is easily caught by the male screw 17 after the holding member 7 is locked to the ink container 2, it is possible to suppress the falling of the holding member 7 from the ink container 2.

  In the above example, the height dimension h1 of the gap formed between the lid 3 and the bottom surface 15b of the step portion 15 and the thickness dimension t1 of the locking portion 41 are substantially equal. The dimension h1 may be shorter than the thickness dimension t1 of the locking portion 41. In this case, the lid 3 and the ink container 2 can be held while pressing the locking portion 41 of the holding member 7.

  In addition, although said example is an example of the liquid container which accommodates ink as a liquid, the liquid to accommodate is not restricted to ink. Further, in the above example, the storage device carries attribute data relating to the contained liquid, but information carried by the storage device is not limited to such information.
