DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insulated bag for keeping foods and beverages cold (including refrigeration or freezing to 0.degree. C. or lower) using a refrigerant such as dry ice or a cooling material.

[0002]

2. Description of the Related Art Conventionally, a bag body and an upper lid covering an upper surface opening thereof are formed of an insulating sheet such as an aluminum sheet as a cold storage transport container for a home delivery service or a leisure cold storage container, and the upper lid is formed of a slide fastener. Insulated bags that can be opened and closed are often used.

[0003]

However, in the conventional cold storage bag, the dry ice or the cold storage material is simply put into the bag body together with the food or beverage, and so on.
There were the following problems.

[0004] The temperature inside the bag cannot be adjusted,
Temperature management was very difficult, as it was too cold or the temperature varied significantly depending on the location. Volatile gas from dry ice often directly touches and alters fresh foods such as vegetables and fruits. In the same bag body, it was not possible to properly use one bag in a refrigerated (frozen) state at 0 ° C. or lower and another in a cool state from 0 ° C. to about 5 ° C. Although it is useful as a simple cold storage container for keeping cold between 0 ° C. and about 5 ° C., it is useful as a refrigeration (freezing) use for maintaining a constant low temperature state of 0 ° C. or less as described above. It was not suitable because it was difficult to adjust or it could not be cooled on average. In the case of using dry ice, it was not possible to use such a method as to regenerate a cold insulator at the same time as keeping or refrigerated food or the like.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to facilitate temperature adjustment in a bag body, to prevent adverse effects of dry ice and the like on foods and the like,
The inside of the bag body should be divided into a refrigeration or freezing room and a cold room, and it should be practically sufficient for refrigeration (freezing) applications that want to maintain a constant low-temperature state of 0 ° C or less. While keeping or refrigerated with ice
At the same time, it is intended to be able to use such as regenerating the cooling material with dry ice.

[0006]

An inner wall plate composed of a heat insulating sheet such as an aluminum sheet, which is detachably disposed in the bag body so as to surround the inside of the back body along the inner wall surface of the bag body, and an aluminum sheet provided with a large number of ventilation holes. A partition plate made of a heat insulating sheet, the both ends of which are detachably supported by a partition support portion provided on the inner wall plate so as to stand up in the middle of the bag body, and an aluminum sheet provided with a large number of ventilation holes as well. And an adjusting plate for adjusting the degree of opening of the ventilation holes of the partitioning plate by detachably polymerizing the partitioning plate.

That is, in the present invention, an inner wall plate, a partition plate, and an adjusting plate which can be detachably disposed in the bag body are prepared. The inner wall plate is disposed around the inner wall surface of the back body to reinforce the back body from the inside. The middle partition plate supports both ends on the inner wall plate and stands up to an intermediate position in the bag body to partition the inside of the bag body. The adjustment plate is placed in the back body so as to overlap the partition plate. In this case, if the number of ventilation holes of the partition plate and the number of ventilation holes of the adjusting plate are completely matched, the entire surface of the ventilation hole of the partition plate will be in an open state. If only some of the pores are opened, and if they are completely staggered, the ventilation holes of the partition plate will be closed by the adjustment plate. Since the inside of the bag body is partitioned by a middle partition plate, if one side of the partitioned part is filled with dry ice or a cooling material, and the other side is filled with food, etc., one side is a refrigerated (frozen) room, and the other side is a cooled room. And both temperatures can be adjusted by an adjusting plate.

The preferred main aspects of the present invention are as follows. Velvet fasteners are provided at both ends of the inner wall plate so as to be superimposed on each other in order to make the inner wall plate stand in a frame shape in the bag body. Velvet fasteners are provided at both ends of the partition plate, and the partition support portions of the inner wall plate are formed of velvet fasteners. While providing a large number of ventilation holes in the partition and adjustment plate in multiple rows,

Therefore, for example, if dry ice or a cold insulator is put in one of the two chambers A and B partitioned by the middle partition plate 3, this chamber A is refrigerated or frozen, and the other is B can be properly used as a cold room. In this case, the amount of cool air entering from one chamber A to the other chamber B can be arbitrarily adjusted by the relationship between the ventilation holes 17 and 23. If the cooling material is sandwiched by dry ice and put in one room A, the cooling material can be regenerated.

In the above example, a velvet fastener is used as a member to be detachably held, but the present invention is not limited to the velvet fastener.

[0020]

As described above, according to the insulated bag of the present invention, the inner wall plate, the partition plate, and the adjusting plate, which are each constituted by a heat insulating sheet such as an aluminum sheet and can be detachably disposed in the bag body. The inner wall plate is arranged along the periphery of the inner wall surface of the back body to reinforce the back body from the inside, and the partition plate stands at the middle in the bag body by supporting both ends of the back plate to the inner wall plate. Then, the inside of the bag body is partitioned, and the adjusting plate is superposed on the middle partition plate and arranged in the back body to adjust the ventilation holes of the middle partition plate, so that the following effects are obtained.

If dry ice or a cooling material is put in one of the two compartments separated by the middle partition plate, this compartment can be used as a refrigeration or freezing compartment and the other compartment can be used as a cold keeping compartment. In the same bag body, some are refrigerated (frozen) below 0 ° C, others are from 0 ° C to 5 ° C.
It is possible to use them properly, such as keeping them cool to about ° C. The amount of cold air entering the other chamber from one chamber partitioned by the middle partition plate can be arbitrarily adjusted by the adjustment plate. If you insert the cold insulator between dry ice, you can regenerate the cold insulator. Temperature adjustment in the bag body is facilitated, and excessive cooling and cooling unevenness are reduced. Volatile gas from dry ice directly touches fresh foods such as vegetables and fruits, thus avoiding the possibility of deterioration.
