[Industrial applications]

 The present invention relates to a cold storage container, and more particularly to a cold storage container suitable for containing processed tableware, freezing and shipping.

[0002]

[Prior art]

 Conventionally, when frozen processed foods are produced by processing seafood such as kazunoko, cod, scallops, etc. by cooking, seasoning, salting, salting, etc. A container containing the above-mentioned processed food is capped and sent to a freezer, where the cap is removed and the containers are staggered so that cool air can spread from the top of the container to the inside. After that, it was frozen at a temperature of −40 ° C. or lower for 24 to 48 hours or more, and after freezing, the lid was capped again and the product was packed, labeled and shipped.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional work process, the cooking and processing workplaces before freezing are different from the workplaces for freezing after that and the process from freezing to shipping, and since workers are attached to each of these workplaces, a lot of work is required. In addition to requiring personnel, the work usually lasts for two days, making it difficult to rationalize, shorten, and save labor. In addition, it is very complicated because it is essential to open the lid after cooking and processing, and then remove the lid again in the freezer compartment.In addition, staggering the containers in the freezer compartment induces cool air to the containers. Since it is necessary to arrange and stack in consideration of the above, workability is extremely poor, and since a large amount of space is required, the storage efficiency of the freezer is reduced. In addition, if the middleman, retailer or consumer of the ship-to destination wishes to refrigerate or refrigerate for shipment to another destination or storage, then the container must be unpacked each time. There was an inconvenience that it wouldn't happen. An object of the present invention is to provide a new and useful cold storage container in order to eliminate such conventional problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the cold storage container of the present invention has an annular guide part formed on the side wall of a container with a foam synthetic resin lid, and a slide ring is rotatably fitted on the outer periphery of the guide part. The guide portion and the sliding ring are provided with at least one cold air hole that communicates the inside and the outside of the container so that they can communicate with each other.

When the container is rectangular, a cold air supply window also serving as a sliding ring operation window is provided on the side wall of the container so as to face the cold air hole on the guide side. Further, a cold air guide groove communicating with the cold air hole on the guide portion side may be provided on the inner surface of the container, or the sliding ring may be formed in an arc shape.

[0006]

[Action]

 When the processed food is frozen and shipped in the cold storage container configured as described above, the cooked and processed processed food is placed in a container, covered, packed, labeled, and then sent to the freezer. In the freezer compartment, the sliding ring of the container is rotated to connect the cold air holes to the cold air holes on the guide side so that the inside and outside of the container are communicated, and then these cold air holes are not hidden by other containers. The containers are piled up normally and closely and the freezing is started. In this case, it is not necessary to stack the containers in a staggered manner, and the cool air flows from the cold air holes on the sliding ring side through the cold air holes on the inner side into the container to freeze the processed food. When the freezing is completed, packing and labeling are already completed before freezing, so the sliding ring is rotated to the original position and the communication between the cold air and the cold air holes on the guide side is cut off immediately before shipping. can do.

When the container has a rectangular shape, the sliding ring is rotated from the cold air supply window that also serves as the sliding ring operation window, and the cold air flows into the container from the cold air supply window through both cold air holes. . In the above work, since the same worker performs the troublesome work such as cooking, processing and packing, and labeling in the same work place, the work efficiency is greatly improved, and it took one day to wait for two days. Can be shortened to a day. It is also convenient because it is only necessary to rotate the slide ring when refreezing or refrigerating, and there is no need to unpack the container. Further, when the cool air guide groove communicating with the cool air hole on the guide portion side is provided on the inner surface of the container, the cool air is easily distributed to every corner of the container, and the freezing time is shortened. Further, when the sliding ring is formed in an arc shape, the opening / closing position of the cold air hole of the sliding ring can be easily set at an arbitrary position on the side wall.

It is rotatably fitted around the outer circumference. Although illustration is omitted, in order to prevent the sliding ring 3 having the cold air holes 6 closed after freezing from naturally rotating due to vibration or the like, the sliding surface between the sliding ring 3 and the guide portion 5 is It is preferable to provide a small protrusion and a recess that can be fitted into and removed from each other by the elasticity of the foamed synthetic resin.

In order to freeze and ship the processed food in the cold storage container having the above-mentioned configuration, first, the processed food is stored in the container 1, the lid 2 is attached, and the packaging and labeling are immediately performed and the processed food is sent to the freezing chamber. Next, in the freezing room, the sliding ring 3 is rotated to communicate the cold air holes 9 with the cold air holes 6 so that the inside and outside of the container 1 are communicated with each other, and then the cold air passages 6 and 9 are connected to each other as shown in FIG. Containers 1 are normally piled up in a direction not hidden by the container 1 and the freezing is started. At that time, the cold air is sent so as to flow into the container 1 from one of the cold air holes 9 and 6, passes through the gap between the processed foods and the cold air guiding groove 8, and reaches every corner of the container 1, The warm food is pushed out from the other cold air passages 6 and 9 to freeze the processed food. In this way, the ventilation in the container 1 is complete and rapid and the freezing time is greatly reduced.

When the freezing is completed, the sliding ring 3 is rotated to the original position to block the communication between the cold air holes 6 and 9, and the product is immediately shipped as it is. This shipping operation can be easily performed by, for example, only the driver of the transportation vehicle, since the packing and labeling of the container 1 are completed before freezing. The same worker can perform the above-mentioned series of work at the same work place in one day. In addition, when re-freezing at the shipping destination or refrigerating by the consumer, it is only necessary to rotate the slide ring 3 and it is not necessary to unpack the container 1, which is very convenient.
