Description

[Detailed description of the device]

[0001]

[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]

 Traditionally, when processed foods prepared by processing seafood such as kazunoko, cod, scallops, etc. by cooking, seasoning, salting, salted and dried are shipped frozen, foamed synthetic products such as round and square shapes are used. A resin container containing the processed food is covered and sent to a freezer. Then, as shown in FIG. 10, the lid is removed and the containers are staggered so that cool air can spread from the upper surface 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 packing and labeling were performed before shipping.

[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 indispensable to open the lid after cooking and processing, and then remove the lid again in the freezer.In addition, staggering of containers in the freezer is arranged with consideration of the induction of cold air into the containers. However, there is a drawback in that the workability is extremely poor because it needs to be stacked, and the storage efficiency of the freezer is reduced because it requires a lot of space. 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 at least a cold air passage communicating with the inside and outside of the container with a side wall of the container with a lid made of synthetic resin, which is tapered at least from the outside to the inside of the container. One is provided, and a cold air passage opening / closing plug is fitted in the cold air passage so as to be able to move in and out laterally.

When the container has a rectangular shape, it is better to provide a cool air passage at a corner portion of the container, so that the volumetric efficiency of the container is improved as compared with a case where it is provided at an intermediate portion of a side wall of the container. Further, it is preferable to provide a cool air guide groove on the inner surface of the container, which communicates with the cool air passage, so that the cool air passage can be secured even when the processed food is fully filled in the container, and the cool air is kept in the container. The freezing time is shortened because it is efficiently frozen in all corners.

[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 freezing room, the cold air passage is opened by pulling the stopper of the container outward to form a gap between the stopper and the cold air passage, and the inside and outside of the container are communicated, and then the cold air passage is concealed by another container. Start the freezing by stacking the containers in the normal direction and refrigerating. In this case, the containers do not need to be staggered and cold air flows into the container through the cold air passage on the side of the container to freeze the processed food. When the freezing is completed, the packing and labeling are completed before the freezing, so the product can be shipped immediately by pushing the stopper inward and closing the cold air passage. In the above work, since the same worker performs the laborious work such as cooking, processing and packing, and labeling, etc. in the same work place, the work efficiency is greatly improved. Can be shortened to a day. Also, for re-freezing or refrigerating, it suffices to simply unplug and plug, and there is no need to unpack the container.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. Example 1 The cold-insulating container of this example is made of foamed synthetic resin, and has a container 1 provided with a lid 2 and a pair of stoppers 3 as shown in FIGS. As the foamed synthetic resin, a styrene foamed resin, a foamed polyolefin resin, a foamed polyurethane resin, or the like having heat insulation property is used.

The container 1 has a round shape, and a pair of thick-walled portions 5 formed at opposite positions of the side wall 4 are provided with a pair of cold air passages 6 for communicating the inside and the outside of the container 1 in the opposite directions. A guide rod 7 for preventing the stopper 3 from coming out is provided upright on the bottom surface of the passage 6, and a cold air guide groove 9 is provided in a cross shape on the inner surfaces of the side wall 4 and the bottom plate 8 so as to communicate with the cold air passage 6. Both sides of the cold air passage 6 are formed in a taper shape from the outside to the inside of the container 1.

The lid 2 is formed in an airtight fitting structure at the joint with the container 1 in order to prevent the cool air in the container 1 from leaking to the outside.

As shown in FIG. 7, the stopper 3 is a wedge-shaped block body for opening and closing the cold air passage 6, has a guide elongated hole 10 in the center, and can freely move in and out in the cool air passage 6 in a lateral direction. In addition, the guide rod 7 is slidably inserted into the elongated guide hole 10 while being fitted so as to maintain airtightness. When the plug 3 is pushed into the cold air passage 6 and the cold air passage 6 is closed, in order to prevent the plug 3 from being pulled out spontaneously due to vibration or the like, both sides of the plug 3 and both sides of the cold air passage 6 are prevented. Has a small protrusion 11 and a concave groove 12 which can be fitted into and removed from each other by the elasticity of the foam 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 that has been cooked and processed is stored in the container 1, the lid 2 is attached, and packing and labeling are performed immediately. Send to the freezer. Next, in the freezer, the cold air passage 6 is opened by pulling the stopper 3 of the container 1 outward to form a gap S between the stopper 3 and the cold air passage 6 (see FIGS. 3 and 4), After the inside and outside of 1 are communicated with each other, as shown in FIG. 9, the cold air passage 6 is orientated in a direction in which it is not covered by another container 1 (in FIG. 9, a direction perpendicular to the paper surface), and the containers 1 are normally piled up in a transparent manner, and then frozen. To start. At that time, the cool air is sent so as to flow into the container 1 from one of the cool air passages 6, passes through the gaps between the processed foods and the cool air guiding groove 9, and reaches all the corners of the container 1, and the other cool air. Hot air is pushed out from the passage 6 to freeze the processed food. In this way, the ventilation in the container 1 is completed and quickly, and the freezing time is greatly shortened.

When the freezing is completed, the stopper 3 is pushed into the cold air passage 6 to close the cold air passage 6, and the product is immediately shipped as it is. This shipping work can be performed only by the driver of the transportation vehicle, for example, because the packing and labeling of the container 1 have been completed at the cooking and processing stages before freezing, and thus these work are not required again. . The same worker can perform the above-mentioned series of work at the same work place in one day. Further, for re-freezing or refrigerating at the shipping destination, only the stopper 3 needs to be pulled out and there is no need to unpack the container 1.

Embodiment 2 As shown in FIG. 8, the cold insulation container of this embodiment has a container 1 having a square shape and a pair of thick parts 5 formed at diagonal corners of the container 1 and a pair of cool air. The passages 6 are provided so as to face each other, and the cool air guide groove 9 is provided in a diagonal direction so as to communicate with the cool air passage 6. 2 is a lid and 3 is a stopper. Other configurations, operations, and effects are exactly the same as in the first embodiment. The cold air passage 6 is thus provided at the corner portion of the side wall 4 because the thick wall portion 5 can be smaller than that provided at the middle portion of the side wall 4, and the volumetric efficiency of the container 1 can be improved. Although not shown in the drawings, the container 1 may have a rectangular outer shape, and only the inner storage portion is rounded, so that the rectangular shape can be adjusted to a desired consumer's preference. The reverse is also possible. Further, at least one cold air passage 6 communicating between the inside and the outside of the container may be provided, but preferably two to four cold air passages 6 are provided to promote the flow of cold air.

[Effect of device]

 According to the present invention, as described above, a cool air passage is provided on a side wall of a container in a tapered shape from the outside to the inside of the container to communicate the inside and outside of the container, and a stopper can be laterally extended and retracted in the cool air passage. Since the cold air passage can be opened and closed by fitting to, the container that holds the processed food, is packed, and is labeled can be frozen simply by opening and closing the stopper. Therefore, since the same worker can perform laborious and time-consuming cooking, processing, packing, and labeling in the same workplace, it is possible to easily rationalize, shorten, and save labor. By the way, the work that used to take two days can be completed in one day.

Further, in the freezer compartment, the troublesome staggered stacking of containers is not required, so that the stacking workability and the storage efficiency of the freezer compartment are improved. Further, re-freezing and refrigerating at the shipping destination can be done simply by opening and closing the stopper, and there is no need to unpack the container, so re-freezing and refrigerating are easy and convenient.

When the container has a rectangular shape, the volume efficiency of the container can be improved by providing the cool air passage at the corner portion of the container as compared with the case where the cool air passage is provided at the middle portion of the side wall of the container. Further, when the cool air guide groove communicating with the cool air passage is provided on the inner surface of the container, the cool air is easily spread to every corner of the container, so that the freezing can be completed completely and in a short time.
