Finally, the bottom lid (32) is attached to the central portion of the bottom member (4) to complete the assembly of the container body (1).

[Modifications, etc.]

In the above-mentioned embodiment, the proximal end pipe (20) of the liquid passage (16) is formed separately from the middle screw member (30) to separate the assembling steps thereof. The one shown in FIG. 4 is the tube on the proximal end side.
It has a remarkable feature in that (20) is integrally formed with the middle screw member (30), and other configurations are the same as those in FIG.

By adopting such a configuration, it is not necessary to provide the base end side tube (20) as a separate member in addition to the middle screw member (30) as shown in FIG. 1, so that the number of parts can be reduced. not only that,
By simply tightening the middle screw member (30), tightening and fixing work of the middle bottle (8) and connecting work to the lower opening (8b) of the proximal side tube (20) can be performed at the same time, and the number of assembly steps can be reduced. There is.

In the case of FIG. 2, the proximal pipe (20) is oriented vertically at the center of the middle screw member (30), and the upper portion (20b) of the proximal pipe (20) is shown.
The lower portion (20c) and the lower portion (20c) are respectively formed so as to project above or below the disc portion (30d) of the middle screw member (30) by a predetermined length. A connecting packing (25) is fitted in the central hole (31a) of the medium bottle protection member (31).

The proximal side pipe (20) of FIG. 3 has its upper part (20b) shorter than that of FIG. 2, and only the connecting packing (25) is fitted into the lower opening (8b) of the middle bottle (8). It is configured to be inserted.

The proximal end tube (20) of FIG. 4 is formed by eliminating the upper portion (20b) shown in FIGS. 2 and 3 and projecting only the lower portion (20c) downward.

The method of coupling the proximal end side pipe (20) and the middle screw member (30) can be arbitrarily changed in design.

[Effect of device]

According to this invention, (1) the relay pipe is integrally formed at a position outside the middle screwed portion of the bottom member into which the middle screw member is screwed, and each connecting pipe is connected to the relay pipe. Since the above-mentioned series of liquid passages are provided, as in the conventional example, with the communication pipe inserted in the narrow insertion port, the first pipe is provided at both ends of the communication pipe.
It is possible to solve the problem that the work of connecting the second connecting pipe is troublesome and time-consuming. That is, since each connection pipe can be easily connected to the relay pipe integrally formed with the bottom member, the respective components constituting these liquid passages can be connected easily and quickly.

(2) Moreover, in the present invention, since the relay pipe is integrally formed on the bottom member, it is not necessary to separately provide a communication pipe as in the conventional example, and the number of parts is reduced.

(3) As described in claim (2), when the base end side pipe of the liquid passage is integrally formed with the middle screw member, as described above, the inner bottle is tightened and fixed and the lower end of the base end side pipe is fixed. There is an advantage that the connecting work for the opening can be performed at the same time and the number of assembling steps can be reduced.
