Description

[Detailed Description of the Invention] This invention relates to a liquid heat-insulating container used to hold liquid such as drinking water in a heated or cooled state for a long period of time.

Such a liquid heat-insulating container consists of a container body and an outer lid that covers the opening of the container body, and the container body generally has an inner container inside which actually stores the liquid. It is true.

The inner container of conventional liquid heat-insulating containers is formed so that the diameter of the opening provided at the top is considerably smaller than the inner diameter of the body in order to enhance the insulation effect. In order to reduce the diameter of the opening to a width larger than the inner diameter of the body, the opening of the medium container and the body must be manufactured separately and then joined together by caulking or other methods. There was a problem that the manufacturing process became complicated and the manufacturing cost increased.

In addition, the inside diameter of the opening is small, making it difficult to clean the inside of the container.
Another inconvenience was that it could only hold small ice cubes.

This idea was made in view of the above circumstances,
To provide a liquid heat insulating container which is normally used as an opening with a small diameter, but whose inner diameter can be made sufficiently large as needed.

That is, in the liquid heat-insulating container according to this invention, the inner container is formed as a wide-mouthed container whose opening diameter is approximately equal to the inner diameter of the body, and the opening of the inner container (opening of the container body) is formed as a wide-mouthed container. A part of the outer cover that covers the outer cover (which is also a part) is provided with a small opening that penetrates the outer cover in the thickness direction, and at the same time, the through hole is provided, and the through hole is provided with a holding means for holding an article such as a pot. The feature is that it can be kept.

Hereinafter, embodiments of this invention shown in the drawings will be described.

FIG. 1 is a partially sectional side view of an example of a liquid heat-insulating container according to this invention.

In the figure, a liquid heat-insulating container 1 is constructed by pivotally connecting a container body 2 and an outer lid 3 with pins 4 in a so-called hinge type manner.

The container body 2 is constructed by filling a heat insulating material 7 between an outer case 5 made of a decorative steel plate and an inner container 6 made of aluminum, plastic, etc. The outer case 5 and the inner container 6 are formed by an annular shoulder member. They are connected via 8.

Note that the heat insulating material 7 does not necessarily need to be filled in the entire interval between the outer case 5 and the inner container 6, and there may be a portion without the heat insulating material.

In this example, the outer case 5 and the shoulder member 8 are joined by a so-called force-fitting method in which the elasticity of the material is used to press-fit them.

Further, the upper end of the middle container 6 is fitted into an annular groove 8a provided in the shoulder member 8 via a packing 9.

The outer case 5 is joined to the bottom member 10 at its lower end by force fitting, similar to the case of the shoulder member.

The container body 2 has three foldable legs 11 (one of which is not shown).

The legs 11 are pivotally connected to the bottom member 10 with pins 12,
These legs are fixed in both the upright and folded states by the action of springs 13 screwed to the bottom member 10.

The container body 2 is also provided with a liquid level gauge 14 and a liquid discharge port 15.

The liquid level gauge 14 is connected to the mounting ports 6a and 6 provided in the medium container 6.
b is connected to a transparent glass tube 14a via rubber joints 14b and 14c.

The liquid discharge port 15 is attached near the bottom of the medium container 6, and has a gasket 15b at the tip of a conduit 15a1 leading from the inside of the medium container 6 to the outside of the container body, and normally closes the outlet of the conduit 15a. However, by turning the knob 15d in the direction that loosens the screws 1' and 5c, the conduit 1 is moved back.
A stopper 15e1 configured to open the outlet of the pipe 5a and a discharge portion 15f connecting the conduit 15a and the outside are provided.

The liquid discharge port 15 is attached by tightening a nut 15g screwed onto its inner end (on the side of the medium container) with an O-ring 15h interposed between it and the inner wall of the medium container.

As mentioned above, the outer lid 3 is pivotally connected to the container body 2 so as to be openable and closable, but there is a locking part 1 on the opposite side of the hinged joint part.
6 is formed.

The lock portion 16 includes a lock lever 1 pivotally attached to the outer lid.
6a, and a spring 16b that always presses the lock lever 16a in the direction of arrow A.

Due to the action of this spring 16b, the hook portion 16c provided at the tip of the lock lever 16a is fixed to the fixing piece 17 of the locking member 17 provided on the outer circumference of the upper end of the container body 2.
a, and thereby the outer lid 3 is fixed in a state covering the opening of the container body 2.

If the lock lever 16a is pressed in the direction opposite to the direction of arrow A, the hook portion 16c will come off from the fixing piece 17a, allowing the outer cover to be opened.

The outer lid has a built-in heat insulating material 31, and an annular packing 18 is provided on the lower surface of the container at a position corresponding to the opening periphery of the container body, covering the entire circumference of the opening, so that the outer lid 3 can be closed. In this state, heat transfer between the inner container and the outside is effectively suppressed.

In this example, the gasket 18 is attached to an annular projection 32 formed on the lower surface of the outer lid 3, but a similar upward annular projection is provided on the waist shoulder member 8, which has a flat lower surface. , you may attach a gasket to this.

A small through hole 19 is formed in the outer lid 3 and extends through the outer lid in the thickness direction, and a lid 20 that can be opened and closed is provided in the through hole 19.

In this example, the lid 20 is screwed onto a threaded portion formed on the inner wall of an enlarged portion formed at the upper portion of the through hole 19 .

A part of the threaded part formed on the inner wall of the enlarged part of the through hole is cut out in the vertical direction to form a gap 19a, and this gap 19a is used to take out the liquid from the liquid discharge port 15. It acts as a necessary ventilation hole.

In the two examples shown in the figures, a porous container 21 is held inside the through hole 19 with its flange 21a locked to the bottom of the enlarged opening.

A pot 22 is further housed inside the porous container.

FIG. 2 is an external view of a part of the porous container 21 with a broken surface. As can be seen from the figure, this porous container has a flange 2 at the top
1a, and a number of through holes 21b are bored in the bottom surface.

A notch 21c is formed in a part of the flange 21a, and this notch 21c is designed to provide ventilation between the inside and outside of the inner container in relation to the gap 19a formed in the inner wall of the through hole. Works as a hole.

The porous container 21 not only serves as an article holding means for storing and holding a pot and the like inside the through hole, but also can be used as a tea bag.

Note that instead of providing such a porous container 21,
A tip with a flange or the like may be directly engaged and held at the bottom of the enlarged portion of the through hole 19 (the stepped portion of the through hole 19).

FIG. 3 shows another embodiment of the liquid heat-insulating container according to this invention.

In this example, the inner diameter near the opening of the middle container 6 (the part indicated by B in the figure) is slightly narrowed.

As in this example, it is advantageous in terms of insulation if the area around the opening of the medium container 6 is narrowed to the extent that it will not be difficult to manufacture or inconvenient for cleaning the medium container or charging ice cubes, etc. .

Next, talking about the effects of this invention, the liquid heat-insulating container according to this invention has a wide-mouthed inner container whose opening is approximately equal to the inner diameter of the body, and the opening of the container body is covered with an outer lid that can be opened and closed. This structure makes it easy to wash the inner container and load ice cubes, making it extremely convenient in practice.

Since the opening of the inner container is wide, it can also store canned juice, etc., depending on the situation.

When attaching a liquid discharge port as shown in Figure 1 to this liquid heat insulating container, the nut tightening work, which was conventionally done by hand, can be done while visually checking, making the installation process extremely easy and reliable. becomes.

Even if the inner container is formed as a wide-mouthed container, there will be no problem with the insulation effect since the opening is always covered with an outer lid having heat insulation properties.

The outer lid has a small-diameter through-hole with a lid that can be opened and closed, and it is possible to inject and pour liquid and observe the inside of the container through this hole, so the entire outer lid can be opened and closed. The amount of heat entering and exiting from the inside of the container can be suppressed to a smaller extent than in the case of the above case.

In addition, this through-hole is provided with a step that forms the bottom of the enlarged opening and an article holding means such as a porous container, so that small items such as cups and spoons necessary for going on vacation can be stored inside the through-hole. It became extremely convenient because it could be stored and carried around.
