Description

[Detailed explanation of the invention] This invention is a portable thermal container that can be carried by hanging it with a hanging string (hereinafter simply referred to as a thermal insulation container).
Regarding.

Conventionally, the main body of such an insulated container has been formed as a cylindrical body with a cross section that is almost circular or oval, and a hanging cord has typically been attached to two cord attachment devices specially provided on the container body via rings called hanging loops.

However, since the above-mentioned conventional heat-retaining containers have a circular or oval cross section, they have the disadvantage that they tend to roll over when they fall. In addition, parts such as a hanging ring are required to attach the hanging string, so
Another problem was that the manufacturing cost was high.

This invention provides a highly practical heat-insulating container that is equipped with a roll-over prevention means and uses the roll-over prevention means as a string attachment tool for attaching a hanging cord, and will be described below.

The thermal container according to this invention has a non-perfect circular annular body formed with a diameter larger than the outer diameter of the container body and provided with a through hole for attaching a hanging string, at least on the upper part of the container body or on the shoulder member. It is characterized by a hanging cord attached to the through hole of this annular body.

Hereinafter, the present invention will be explained based on drawings showing embodiments.

FIG. 1 shows an example of a heat-insulating container according to this invention, in which a is a perspective view, b is a plan view, and c is a bottom view. Moreover, FIG. 2 is a partial sectional view showing the AA cross section in FIG. 1b.

In these figures, a heat insulating container 1 includes a cylindrical container body 2 that contains a liquid, a stopper 4 that can open and close an opening 3 of a shoulder member 9 provided at the top of the container body 2, and a stopper 4 that can be opened and closed. It is equipped with a hanging string 5.

The container body 2 is made up of an outer case 6 made of a decorative steel plate or the like, and a vacuum double bottle 7 for storing liquid stored therein. The upper part of the outer case 6 is bent inward to form a fixed edge 6a.
a is clamped and fixed by the flange 8a of the mounting ring 8 and the hanging portion 9a of the shoulder member 9. The mounting ring 8 is fixed to a plurality of mounting bosses 9b (two are shown) provided on the shoulder member 9 with screws 10. Upper edge of double vacuum bottle 7 and shoulder member 9
A packing 11 is arranged between the two. In the illustrated example, a vacuum double bottle is used as the inner container, but a plastic or metal inner container may also be used.

The shoulder member 9 has a female thread 9c on the inside, into which a plug body 4 having a male thread 4a on the outer periphery is screwed. Thereby, the opening 3 of the shoulder member is closed so as to be openable and closable. The plug body 4 has a built-in heat insulating material 4b, and a small-diameter fitting part 4 that fits into the vacuum double bottle 7 at the bottom thereof.
c, and a packing 12 is attached to the base of the fitting portion. When the stopper 4 is tightened, that is, when the stopper is closed, the seal 12 is attached to the shoulder member 9.
9d to prevent the internal liquid from flowing out. The inner wall of the shoulder member 9, on which the internal thread 9c is provided, is partially cut out in the vertical direction deeper than the thread trough to form a liquid channel 9e, which can be accessed without removing the stopper 4. If you loosen the gasket 12 and create a gap between the bottom surface 9d of the shoulder member 9, the spout 9f will pass through the liquid path 9e.
You will be able to pour out liquid from the In the illustrated example, the outer cover 13 is covered on the outside of the stopper 4, and there is a stopper 1 between the outer cover 13 and the stopper 4.
4 are stored. The top 14 is held on the shoulder member 9, and the outer lid 13 is placed on the shoulder member 9.
It is held in a state where it is screwed into an upper outer circumferential screw 9g provided on the outer circumferential part of.

Next, in the illustrated example, a lower outer circumferential screw 9h is provided on the outer circumference of the hanging portion 9a of the shoulder member 9, and a first
A rectangular annular body 15 as shown in FIG. b is screwed. A through hole 16 serving as a string attachment means is bored in the projecting portion of the annular body 15. The hanging cord 5 is passed through the through hole 16 from top to bottom, and the tip of the hanging cord 5 passing through the through hole 16 is attached to the through hole 16.
A stopper 17 as shown in FIG. 1d is attached which is large enough not to pass through and can be detachably attached to the hanging cord. Thereby, the hanging cord 5 is attached to the annular body 15. The string attachment means is not necessarily limited to such a through hole; for example, a hanging ring or the like may be provided and the hanging string may be attached to this, but the structure is simpler if the above-mentioned through hole is provided. Therefore, it is preferable. The hanging string attached in this manner allows the thermal container to be hung and carried. The toroidal body does not necessarily have to be circular;
In addition to the rectangular shape shown in FIG. 1, it is formed into a non-perfect circular shape that is difficult to roll over, such as a hexagonal or other polygonal shape, or an oval shape as shown in FIG. 3.

FIG. 4 shows a first annular body 1 attached to the upper part of the container body 2.
5 is provided, and an example in which a second annular body 15' is also provided at the bottom of the container body 2 (to be more precise, the bottom member 19) is shown. In this example, the first annular body 15 provided at the top is integrally formed with the shoulder member 9, and the second annular body 15' provided at the bottom is integrally formed with the bottom member 19. ing. The bottom member 19 is screwed onto a bottom member attachment ring 18 fitted to the outer case 6, and a cover 21 is provided inside the bottom member 19.
A holder 20 for holding the vacuum double bottle 7 is screwed through the holder 20. In this case, the second annular body 15' also
It may be manufactured separately from the bottom member and attached to the container body or the bottom member by screwing or the like. In the example shown in FIG. 4, two through holes 16 and 16' are provided in parallel at one location of the annular body 15, and a hanging string 5' is passed through these in a U-shape and attached. If the first and second annular bodies are provided in this way, the hanging cord can be passed between only the first annular body or between the first and second annular bodies depending on the purpose of use. This is convenient because it allows you to This is also advantageous in preventing the heat insulating container from rolling over.

FIG. 5 shows an example in which a roughly U-shaped handle 22 made of an elastic body is attached in place of the hanging cord 5 by fitting both ends of the handle into the through hole. Providing such a handle makes it possible to stably hold the heat insulating container. In this case, the handle 22 can be attached by simply compressing it in the longitudinal direction using its elasticity and fitting its both ends into the through holes of both annular bodies, making attachment and detachment extremely easy.

FIG. 6 shows an example in which the annular body 15 is attached to a heat-insulating container equipped with an inner container 7' made of stainless steel. In this case, the annular body 15 is attached to the welded portion 23 appearing on the outer periphery of the container body by a so-called force-fitting method in which the annular body 15 is fitted by utilizing the elasticity of the material. This annular body 15 also has the effect of serving as a cover to hide the weld line.

As explained above, the insulating container according to this invention has a diameter larger than the outer diameter of the container body, and has a rectangular shape.
It has an annular body formed in a non-perfect circle, such as a hexagonal shape, other square shape, or oval shape, so that it is difficult to roll over, so the container body is protected when it falls over or comes into contact with other objects, and it also protects the container from falling. However, rolling can now be effectively prevented. Moreover, since the annular body is used as a hanging string attachment tool, there is no need for special string attachment tools such as hanging rings.
It is structurally simple and has the effect of increasing installation strength.
