Since the connecting member 39 of the present invention is entirely made of an elastic material such as rubber, when connecting the lower opening pipe 37 of the inner container 8, the spout unit 46, the tube 43, etc., They can be easily connected while maintaining airtightness, and the simple tightening rings 44, 47 can make the connection more complete. Moreover, the vibrations generated in the inner container 8 can cause damage to the pouring unit 46 and the water level pipe 71.
Furthermore, even if a shock is applied to the spout unit 46 or the water level pipe 71, it will not be transmitted to the inner container 8. As a molded liquid container, it has excellent impact resistance.

The connecting part between the outflow part 41 and the spouting part unit is the connection part 4 of the spouting part unit 46 as shown in the embodiment.
An annular rib 74 is provided on the outer periphery of the spout unit 8 , an annular groove 75 is formed on the inner periphery of the outflow portion 41 , and an annular rib 76 is formed on the outer periphery of the spout unit 46 . It is preferable that it is elastically fitted into the annular groove 75 and the tightening ring 47 is fitted next to the annular rib 76 for coupling.

Further, the joint portion between the connecting pipe 40 and the lower port pipe 37 is the fourth
As shown in the figure, an annular rib 77 is provided on the outer periphery of the connecting pipe 40.
The annular rib 77 can be used to prevent the tightening ring 44 from coming off.

In particular, since the lower tube 37 of the inner container 8 is made of glass, its dimensional accuracy is low, and if the connecting member 39 is made of hard plastic, a packing or the like must be used, and the connecting structure However, in the present invention, since the connecting member 39 is made of an elastic material, the structure can be extremely simple.

Further, a vertical rib 45 is formed on the outer periphery of the connecting pipe 40, and the connecting pipe 40 is fitted between the lower mouth pipe 37 and the center hole 38 of the tightening body 34, so that the tightening body 34 The lower part of the inner container 8 is held and the connecting pipe 40 acts as a cushion, which has the effect of significantly improving the impact resistance of the magic bottle. In particular, the lower opening tube 37 in a double-ended vacuum bottle is a part that is extremely susceptible to damage, and is fitted to the closing body 34 via a connecting tube 40 made of an elastic material with vertical ribs 45 formed on the outer surface. By doing so, the position of the inner container can be determined while protecting the lower mouth pipe 37.

Note that a cover 78 is usually provided in the lower half of the inner container 8 of the magic bottle to protect the inner container 8 and to prevent the contents from leaking out even if the inner container is damaged. However, in the present invention, the cover 78 is cut in the middle of the lower mouth pipe 37 of the inner container as shown in FIG. It is preferable to insert and hold it between the connecting pipe 40 and the lower mouth pipe 37 of the middle container 8 from the upper end.

Furthermore, the connecting member 39 of the present invention is a branch pipe branched into three directions, each of which has a connecting pipe 40 connected to the lower mouth pipe 37, an outflow part 41 connected to the spout unit 46, and Since the metering tube 73 is connected to the tube 43, all the poured out liquid can be distributed to the necessary parts using a single member, and the structure is simple. The assembly work becomes extremely simple.
