Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a heat-retaining container such as a cooler box or a water jar.

[Conventional technology]

Conventionally, as shown in FIG. 7, a cooler box or the like having a box-shaped heat insulating layer has an outer container 1 and an inner container 2 made of synthetic resin formed separately, and a space inside the outer container 1. The inner container 2 is arranged and fitted around the outer periphery of the opening, the space provided between the outer container 1 and the inner container 2 is filled with a heat insulating material 3, and the heat insulating lid 4 is attached to the opening. Ta.

[Problem that the invention attempts to solve]

Therefore, the appearance is almost the same, and there is not much freedom in design.Moreover, because the outer container 1 has a mold draft during molding, the cross-sectional area decreases from the opening to the bottom, resulting in an unstable shape. It was hot. In addition, when providing a water inlet, for example, to take out the liquid stored in the inner container 2 to the outside, as shown in FIG.
The pipe 6 is inserted into the hole 5 provided at the bottom, and the pipe 6 is watertightly connected with the nut 9 via the gaskets 7 and 8, and the water tap 10 is attached. There was a risk that the liquid stored in the inner container 2 would leak due to loosening or deterioration of the packings 7 and 8, enter the heat insulating material 3 between the inner container 2 and the outer container 1, and rot.

Therefore, an object of the present invention is to provide a heat-retaining container that is easy to assemble, has stability, and has an improved degree of freedom in design.

4b, continuous and integrally formed from the mouth edge 14f of the inner container 14, and further outer plates 15, 15
Continuing below the outer sole plate 17 is a reinforcing rib 19c.
It is integrally formed on the outer side of the bottom surface 14e of the inner container 14 via.

Further, locking portions 21, 21 of the strap 20 are formed on the upper portions of the outer plates 15, 15, respectively.
A drainage conduit 22 and a drain port 23 communicating with the inside of the inner container 14 are integrally formed in the lower part of one of the outer plates 15.
It is designed to drain water inside.

Open remaining opposing sides 1 of the inner container 14
4c, 14d are provided with outer plates 16, 16, and outer plates 15, 1 integrally formed with the inner container 14.
5 and the outer bottom plate 17 by fixing members 25 such as screws to form an outer container 26.

These outer plates 16, 16 are connected to the inner container 1, respectively.
4 mouth edge 14q and the edge 1 of the outer plates 15, 15
The inner container 1
It is fitted to the outside of the side surfaces 14c and 14d of 4 with an appropriate interval, and is attached by a fixing member 25 such as a screw to form an outer container 26, and the head of the screw 25 is connected to the outer plate 16, It protrudes from 16 by a dimension l.

Then, the side surfaces 14a, 14b, 1 of the inner container 14
4c, 14d and outer surfaces 15, 15 and outer surface 1
6 and 16, and between the bottom surface 14e and the outer sole plate 17, a heat insulating material 18 such as polyurethane foam or expanded polystyrene is provided, respectively.

Further, an inner plate 13a is provided at the upper opening of the main body 12.
A heat insulating cover 13 filled with a heat insulating material 18 is attached by a cover locking member 28 between the outer panel 13b and the outer panel 13b.

The heat-insulating container 11 configured in this manner has the inner container 14, the outer plates 15, 15, and the outer bottom plate 17 integrally formed, so there is no need for plate slopes of the mold, and it is stable and has an easy design. The degree of freedom is improved, and
Since the drain conduit 22 and the drain port 23 are integrally formed, the structure is simple and there is no fear of water leakage between the inner container 11, the outer plate 15, and the outer bottom plate 17.

Furthermore, since the outer plates 15, 15 and the outer bottom plate 17 are provided through the reinforcing ribs 15a, 15b, 15c, they have sufficient strength to prevent deformation, and the outer plates 16, 16 are sealed. In addition to being fitted through the gasket 27, it is also attached with a fixing member 25 such as a screw, so it is securely fixed and prevents water from entering the space between the inner and outer containers. Prevents decay.

Furthermore, the head of the fixing member 25 such as a screw is attached to the outer plate 1.
6, so when placed with the outer plate 16 side down, it serves as a leg and does not damage the outer plate 16.

In the above embodiment, the drain port 23 is provided at the lower part of the outer plate 15, but it may be provided integrally with the bottom surface 14e of the inner container 14 and the outer bottom plate 17.
Also, the heat insulating material 18 is attached to the side surfaces 14c and 1 of the inner container 14.
It is also possible to form two pieces in advance and assemble them so that they can be attached from the 4d side, thereby simplifying the assembly process.
