Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable liquid container such as a thermos flask, and more particularly to a structure for connecting an outer case of a portable liquid container.

Hereinafter, a liquid container according to an embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a teapot-shaped thermos flask, which is a specific example of the liquid container of the present invention.

The body diameter of this thermos bottle body 1 is relatively large.

The main body 1 is constructed by disposing an inner container 3 for containing a liquid made of a vacuum double layer inside an outer case 2 made of synthetic resin.

Reference numeral 4 indicates a stopper, and 5 indicates a handle.

The exterior case 2 is divided into an upper case 6 and a lower case 7 at its maximum diameter.

A beak 8 serving as a spout and a plug insertion hole 9 into which the plug 4 is inserted are formed in the upper part of the upper case 6.

Further, a support member 10 for pushing up and supporting the inner container 3 is screwed onto the bottom of the lower case.

Further, tubes 11 and 12 to be screwed together are integrally formed in each opening of the upper and lower cases 6.7.

The threaded cylinder 11 has a female thread 13, and the threaded cylinder 12 has a male thread 14.

A stepped portion 15 is provided at the base end of the outer periphery of both screw cylinders 11 and 12, respectively.
．． '16 is formed.

A body ring 17 made of a relatively hard synthetic resin is fitted onto the outer periphery of the screw 11 and 12 that is on the outside when screwed together (threaded cylinder 11 in this embodiment).
For positioning, longitudinal protrusions 18, 18 are formed on the outer circumferential surface of the threaded cylinder 11, while longitudinal protrusions 119 are formed on the inner circumferential surface of the barrel 17 to fit with the protrusions 18 and 18. , 19 are formed (see Figure 2).

Note that the protrusions 1B and 18 also have the function of reinforcing the threaded cylinder 11.

Then, with the body ring 17 fitted around the outer periphery of the threaded cylinder 11, the threaded cylinders 11 and 12 are screwed together to form the upper and lower cases 6.
．． 7 are combined, the barrel ring 17 connects both threaded cylinders 11, 1.
It is clamped and fixed between the two step portions 15 and 16.

This body ring 17 has an outer diameter larger than the maximum diameter of the outer case 2, and serves both as a decoration and a protector for the joint between the upper and lower cases 6°7, as well as for correcting distortion of the threaded cylinder 11. It also has the effect of making screwing easier, and this becomes more effective as the diameter of the outer case 2 becomes larger.

In this embodiment, the acid thread cylinder is formed on the upper case 6 side, and the male thread cylinder is formed on the lower case side, but this may be reversed.

In that case, the body ring 17 is fitted onto the outer periphery of the threaded cylinder 12 on the lower case 7 side.

It goes without saying that the present invention can also be applied to the illustrated thermos kettle and other liquid containers.

Next, the effects of the liquid container of the present invention will be listed below.

That is, according to the present invention, (1) The threaded cylinder 11.1 is formed in the opening of the upper and lower cases 6.7, which are constructed by dividing the outer case 2 at its maximum diameter.
2, the body ring 17 having an outer diameter larger than the maximum diameter part of the outer case 2 is fitted to the threaded cylinder 11 or 12 which becomes the outer side when screwed together, so that the body ring 17 does not come into contact with the floor etc. when the main body falls over. This effectively absorbs the impact of a fall, protects and reinforces the joint between the upper and lower cases 6 and 7, and also hides the joint between the upper and lower cases 6 and 7. (2) When screwed together, the outside Since both threaded barrels 11 and 12 are screwed together with the body ring 17 fitted around the outer periphery of the threaded barrel 11 or 12, the distortion of the threaded barrel 11 or 12 is corrected, and the upper and lower cases 6 (3) A stepped portion 15 formed at the base end of the threaded cylinder 11.12 when the upper and lower cases 6.7 are connected to the body ring 17;
Since the body ring 17 is sandwiched and fixed between the body rings 16 and 16, there is a practical effect such that the fixing structure of the body ring 17 can be significantly simplified.

Claims (1)

[Scope of utility model registration request] The outer case 2 of the main body 1 equipped with the inner container 3 for storing liquid is divided into an upper case 6 and a lower case at its maximum diameter, and each opening of the upper and lower cases 6. Threaded cylinders 11 and 12 to be screwed together are each integrally formed, and stepped portions 15° and 16 are respectively formed at the base end of the outer periphery of each of the screw cylinders 11 and 12. A trunk ring 17 having an outer diameter larger than the maximum diameter of the outer case 2 is fitted onto the outer periphery of the cylinder 11.
