When placed on the bottom surface 25a of the holder 25 by any of f, the distance H between the bottom surface 25a of the holder 25 and the spout 14 of the ink container 10 can be kept substantially constant.

That is, as in the comparative example shown in FIG. 7, when the ink container 10 is placed on the bottom surface 25a of the holder 25 by the bottom surface (reference surface) 11f composed of a three-layer panel,
The bottom surface 25a of the holder 25 and the spout 14 of the ink container 10
Is unstable because the thickness of the three-layer panel changes due to the gap between the panels, but as in the present invention, the bottom surface (reference surface) 11f of the single-layer panel makes the ink container 10 When placed on the bottom surface 25a, the distance H is substantially constant. For this reason, the alignment between the spout 14 and the discharge nozzle 26 becomes easy.

Further, the spout 14 is a spout mounting surface 1.
Since it is fixed to only one panel 20a, the mounting work of the spout 14 becomes easy.

As shown in FIG. 2, the cap 15 includes a cap body 15a mounted on the spout 14 and a cylindrical support portion 15b abutting on a spout mounting surface 11a provided on the outer periphery of the cap body 15a. The cylindrical support 1
The spout 14 can be effectively protected by 5b. In this case, the cylindrical support portion 15b is
a, the cap 15 can be received by the cylindrical support portion 15b even if a force is applied to the cap 15 from the outside, so that the spout 14 does not bend.

[0030]

As described above, according to the present invention,
The spout mounting surface can be configured rigidly, and thereby the spout can be stably and firmly mounted on the spout mounting surface. For this reason, external pressure is not applied to the spout, and the spout does not bend or come off the spout mounting surface. Also, since the spout is fixed to only one panel of the spout mounting surface, the work of mounting the spout can be easily performed. Further, the distance from the spout of the spout mounting surface to the reference surface becomes constant. For this reason, it becomes easy to align the device on which the container for viscous contents is placed with the spout.
