DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foamed synthetic resin container for cooling and keeping articles that need to be kept cool, such as fresh foods, seafood and other pharmaceuticals.

[0002]

2. Description of the Related Art A foamed synthetic resin container is a material having a low specific gravity and excellent heat insulation properties.
It used to store ice and fresh fish and used it for transportation, etc.Depending on the type of fish, some fish did not lose freshness even if they entered ice water, but some fish lost freshness , A container formed with a drain hole at the bottom of the container by fish,
And a container without a drain hole. Also, in the case of a container made of only a foam, if the wall thickness is not considerably increased, light beams pass through and the ice contained therein can be easily melted, so it is necessary to take measures against this.

[0003] Further, the present invention is configured such that they can be used for other articles requiring cold insulation. A container for storing and transferring medicines and the like has an outer peripheral wall made of a hard material. Although various configurations were applied to the inside of the product, some of the medicines that do not need to be held firmly are required to have containers that can be stored and transported in a slightly simpler container. It had been.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to provide a foamed synthetic resin container for cooling which can be adapted to articles requiring cooling without changing the structure of the conventional container.

[0005]

In order to achieve the above object, the present invention accommodates a foamed synthetic resin container having a drain hole at the bottom and ice having a drain hole at the bottom similarly to the container. In combination with a synthetic resin bag, ice and articles requiring cooling are stored in the bag, and the synthetic resin bag is placed in the foam synthetic resin container, and is used for transfer, management and the like. A container, which is obtained by depositing metal on the bag, or by changing the color of the container itself to a color that is difficult to transmit light, and using the container alone without using the bag, or a combination of these.

With the above-described structure, it takes a long time to melt the ice inside, and it is possible to maintain the freshness of perishable foods and the efficacy of pharmaceuticals for a considerable time. In this case, a transparent bag is used. Even so, freshness can be maintained for a considerable time, and a bag provided with a metal coating formed by metal deposition is most suitable.

[0007] The water from which the ice has melted accumulates in the container through the hole in the bag, and is then discharged to the outside through the water drain hole in the container. And, for example, can maintain the freshness of fresh food products and the utility of pharmaceuticals.

[0008] If the metal vapor deposition is aluminum vapor deposition, the cooling effect can be improved, and it can be produced economically at low cost, and a stable product can be provided.

Further, by making the color of the container itself a color that does not easily transmit light, it is possible to further enhance the cooling effect, and it is possible to further enhance the cooling effect by combining these.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described in detail with reference to FIG. 1. A foamed synthetic resin container 3 having a bottom 1 formed with water drain holes 2,. And a synthetic resin bag 6 for accommodating ice 7 provided with appropriate drain holes 5... At positions that are difficult to match with the drain holes 2. 8 is housed in the foamed synthetic resin container 3 for use in transportation, management, etc., and the bag 6 is provided with a metal coating formed by metal deposition. Or a color in which the color of the container 3 itself is difficult to pass light rays.

With the above-described structure, it takes a long time for the ice 7 inside the bag 6 to melt, and the freshness and utility of the article 8 can be maintained for a considerable time.
From the hole 5 of the container 3 and then the drainage hole 5 of the container 3
・ ・ It is discharged to the outside. In this case, the metal deposition is preferably aluminum deposition, which is more expensive, but using a bag in which an aluminum foil or another metal foil is bonded can further increase the effect. In FIG. 1, the shape of the bottom 1 is slightly raised at the center, but such a shape of the bottom 1 can be used without any limitation. Furthermore, various forms are also conceivable for the whole form of the container 3, but FIG.
As shown in the second embodiment, when the containers 13 are stacked and stored or transported, draining of the bottom 11 is performed so that the melted water of the upper container 13 does not stain the outer wall of the lower container 13. It can be said that the configuration of the container 13 provided with the vertical hole 14 communicating with the hole 12 is a preferable configuration. In addition, in addition to these, a drain hole is provided at the bottom of the container, and any form can be used as long as ice can be stored. In addition, fish is described as an example of stored goods. However, it goes without saying that it can be used not only for fresh fish but also for articles that require cooling.

In particular, when a container for fresh fish or an elongated container is required, the drainage holes of the container are not provided at the four corners of the container, but are preferably provided at the side wall portions, as shown in FIGS. 3 and 4. In many cases, a long container such as bonito or mackerel is required even for fish, and in the case of such a container 23, it is difficult to drain the thawing water to the outside smoothly even if drain holes are provided in the four corners. A drain hole 22 is provided at the bottom 21 of the side wall.

[0013]

According to the present invention having the above-described structure, it takes a long time to melt the ice inside, and it is possible to maintain the freshness and the effect of the articles that need to be kept cool for a considerable time. The water accumulates in the container through the hole of the bag, and is then discharged to the outside through the drain hole of the container. In addition, if the bag inside the container is metal-deposited, the cooling effect can be maintained for a long time, and even if the color of the container is a color that is hard to pass light, it takes a long time to melt the ice inside, It can maintain the freshness and the effect of the article for a proper time, and by using these in combination, the cooling effect can be further enhanced.
