is attached so that the liquid level in the water level pipe 10 can be visually observed through the see-through window 13.

An inner stopper 14 is in close contact with the upper surface of the bottle mouth holder 3a of the shoulder body 3, and a water lift pipe 15 and a water injection pipe 16 are integrally attached to the inner stopper 14. Inner stopper 14
A lid 17 that can be opened and closed using a rear hinge 18 as a fulcrum is in close contact with the top surface, and an air pump (not shown) built in the lid 17 operates to supply pressurized air to the air. Medium bottle 2 via stopper 14
As a result, the liquid in the medium bottle 2 is poured out through the water lift pipe 15 and the water injection pipe 16 of the medium stopper 14.

Reference numeral 20 denotes a medium bottle protector for covering and protecting the medium bottle 2, which is made of a relatively flexible material such as soft polyethylene, and is fitted to the outer periphery of the side and bottom portions of the medium bottle 2. An opening 2 is provided at the lower end of this medium bottle protector 20.
1 is formed, and this opening is in close contact with the outer circumferential surface of the lower mouth pipe 2c of the medium bottle 2, and the upper end of the connection gasket 6 is fitted into the outer surface of the lower mouth pipe 2C and the opening 21. are doing. Further, on the outside of the lower end opening 21 of the medium bottle protector 20, an annular stepped portion 22 concentric with the opening is provided to protrude in the horizontal direction.

Note that this stepped portion 22 does not necessarily need to be continuous in an annular shape as long as it is concentric with the opening 21.

An annular member 30 having a female thread on the inner peripheral surface is attached to the inner surface of the lower end of the exterior body 1, and a bottom body 31 is screwed onto the female thread of the annular member 30.

A female thread 31a is provided on the inner circumferential portion of the bottom body 31, and a connecting gasket 6 fitted to the lower mouth pipe 2c of the medium bottle 2 is projected from the center of the female thread 31a as described above. An annular tightening body 40 with an opening is screwed together so as to be freely retractable.

This tightening body 40 is composed of two parts: a tightening screw body 43 and a tightening support body 44. That is, the tightening screw body 43 is screwed into the female screw 31a of the bottom body 31.
A tightening support 44 is slidably mounted on the upper surface, and the stepped portion 22 of the medium bottle protector 20 fits into the inner surface of the upper end of the tightening support 44. A plurality of ribs 44a protrude radially from the outer circumferential portion of the tightening support 44, and an insertion opening 4 cut out in a U-shape is provided on one side through which the connecting tube 8 serving as a connecting means is inserted.
4b is formed. The outer end of the rib 44a engages with a plurality of guide grooves 30a formed at the upper end of the annular member 30, and is guided in a vertically movable manner.

Next, a method of assembling the liquid container having the above structure will be explained.

First, attach the medium bottle protector 2 to the side and bottom of the medium bottle 2.
0, one end of the connecting gasket 6 is fitted into the lower mouth pipe 2c of the medium bottle 2 and the opening 21 of the medium bottle protector 20, and the tightening ring 7 is attached. In this state, the medium bottle 2 and the medium bottle protector 20 are inserted into the container body 1. Then, connect the connecting pipe 8 to the other end of the connecting gasket 6, connect it to the water level pipe 10 via the connecting tube 9, and tighten the connecting pipe 8 to the support member 4.
When the tightening screw body 43 is rotated and screwed upward with respect to the bottom body 31, the tightening support body 44 engages with the rib 44a and the guide groove 30a. Because rotation is prevented by
It moves only upward while slidingly contacting the tightening screw body 43, and the upper end of the tightening support 44 pushes up the bottom of the medium bottle 2. As a result, the upper end opening 2 of the medium bottle 2
a to the bottle mouth holder 3a through the mouth rubber 4,
The medium bottle 2 can be tightened and fixed.

It goes without saying that the order in which the connecting pipes 8 are attached is not limited to the above-mentioned order.

In any case, as in the case of using a conventional medium bottle having an opening only at the upper end, the medium bottle 2 can be fixed by simply rotating the tightening screw body 43.

Therefore, even if the container is accidentally tipped over, the medium bottle protector 20 will fit into the side and bottom of the medium bottle 2, and the medium bottle 2 will be positioned at the center of the exterior body 1, and the medium bottle Since the step portion 22 of the protector 20 is supported by the tightening body 33, external force is hardly applied to the medium bottle 2.
The inner bottle 2 does not come into contact with the outer package 1 and break,
Furthermore, the fall impact is buffered by the medium bottle protector 20 and the connecting gasket 6, and is not directly transmitted to the bottom pipe 2c of the medium bottle 2, so there is no risk of damage to the bottom pipe 2c.

The present invention is applicable not only to the air pot as in the embodiment, but also to so-called hand pots in which liquid is poured by holding the handle and tilting the main body. Further, in the above embodiment, the opening 2b of the medium bottle 2
Although the lower mouth pipe 2c is shown as being integrally provided, it goes without saying that the lower mouth pipe may be provided as a separate body and provided in the opening 2b through packing or the like.
Furthermore, the water level pipe 10 has its upper end connected to a water injection pipe 16.
By connecting it to, it can also be used as an injection channel, and in this case, the water lift pipe 15 of the inner stopper 14 becomes unnecessary.

(f) Effect of the device As is clear from the above explanation, according to the present invention, the tightening body is screwed to the tightening support that presses the lower part of the medium bottle upward, and the bottom body, and the tightening support is connected to the bottom body. It consists of a tightening screw body that moves the body upward, and a tightening support body,
In addition to providing an insertion opening that opens upward into which a connecting means for connecting the lower end opening of the medium bottle and a water level pipe provided on the outer surface of the outer casing is inserted, a plurality of ribs are provided on the outer periphery of the container. Since the connecting means is engaged with the guide groove provided on the main body and is prevented from rotating, the connecting means can be inserted into the insertion hole and the tightening screw body can be rotated to prevent the middle part from rotating without applying any force to the connecting means. The bottle can be easily attached to the exterior body, making the work extremely easy. In addition, the water level pipe and the opening at the bottom of the medium bottle are connected through possible connection tubes and gaskets provided at both ends of the connecting tube, so external forces are absorbed by these tubes and gaskets and directly transmitted to the medium bottle. Not only does it reduce the risk of damage, but it also has the effect of absorbing misalignment between the water level pipe and the lower end opening of the medium bottle, and preventing excessive stress from concentrating on one side.
