Description

  The present invention relates to a freezing foam box that can be used in a series of processes from a refrigeration / freezing process to a transportation process for foods and the like that require low-temperature management.

  Conventionally, frozen foods such as meat and fish, fresh foods such as vegetables, and refrigerated foods such as dairy products have been required to be controlled at a low temperature in order to maintain freshness and prevent quality deterioration. In particular, in order to maintain a constant temperature without interruption during distribution while managing in a temperature range according to each food, not only temperature management in processing facilities and retail stores, but also storage warehouses and refrigerated trucks and containers It is necessary to manage at a certain temperature even in the transportation process. Therefore, a cold chain (low temperature distribution system) has been established, which is a distribution system that distributes frozen foods and fresh foods from production areas to consumption areas while maintaining a low temperature consistently.

  To prevent this cold chain from being interrupted, for example, food such as meat, fish, and vegetables that has been packed and shipped from farmers in the past has been used in cardboard boxes and wooden boxes in collection boxes such as agricultural cooperatives and large refrigerators in fruit collection centers. Refrigerated / frozen using a metal pan or metal bread.

  Next, when these foods are transferred to a refrigerated truck or the like and transported to each market or retail store, it is necessary to prevent the food from being thawed (temperature deviation) without being exposed to the outside temperature as much as possible. For this purpose, a method of cold-packing cardboard boxes and wooden boxes packed with foods controlled at low temperatures in a foamed polystyrene container having a cold-retaining function is widely used. That is, low temperature food that is packaged with cardboard or the like is cold-packed in a styrofoam container to prevent temperature deviations during operations that are exposed to outside air temperature.

  In addition, a freshness-keeping container and method (for example, see Patent Document 1) for keeping the cold chain and keeping the freshness of leaf vegetables in the high temperature period are also disclosed.

(Embodiment 1)
A freezing foam box according to Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1A shows a state before the freezing foam box 1 is assembled, and the freezing foam box 1 includes an inner box 2 and an outer box 3 formed of foamed synthetic resin. The freezing foam box 1 is packed with items requiring low-temperature management, for example, frozen foods such as meat and fish, and refrigerated foods such as vegetables and dairy products. The foamed synthetic resin is a polyolefin resin such as polystyrene, polyethylene, or polypropylene.

  First, the shapes of the inner box 2 and the outer box 3 constituting the freezing foam box 1 will be described. As shown in FIGS. 1 and 2, the inner box 2 has a rectangular (polygonal) bottom plate 2a and side plates 2b, 2c, 2d, and 2e that are integrally provided upright from the respective sides around the bottom plate 2a. In the first embodiment, a substantially box shape having an opening surface on one surface is formed. The side plates 2b, 2c, 2d, and 2e are formed with a plurality of vent holes that form gaps between the internal space and the outside air. In the first embodiment, the vent ports are the bottom plate 2a of the inner box 2. Is a notch groove 2f having a concave shape formed from the upper edge surface of the side plates 2b, 2c, 2d, and 2e toward the lower side. And, as shown in FIG. 4, the temperature and humidity of the food (packing material) packed in the inner box 2 can be controlled by these notched grooves 2f even when the plurality of inner boxes 2 are stacked in a large freezer. It can be easily adjusted by adjusting the outside air. The pitch width of the notch grooves 2f can be freely changed according to the type of packing material packed in the freezing foam box 1 such as a relatively wide width when packing meat.

  As shown in FIGS. 1 and 3, the outer box 3 includes a rectangular (polygonal) lid plate 3 a and side plates 3 b, 3 c, 3 d, 3 e erected integrally from each side around the lid plate 3 a. In the first embodiment, a substantially box shape having an opening surface on one surface is provided. In order to maintain the cold insulation function in a tight fitting state (sealed state) in which the outer box 3 and the inner box 2 do not have a gap, the side plates 3b, 3c, 3d, 3e are connected to the side plates 2b, 2c, 2d, and 2e have a size that fits closely from the outside. The side plates 3b, 3c, 3d, and 3e of the outer box 3 are provided with a recess 3f for improving workability such as making it easier to remove the inner box 2 from the outer box 3 in the state shown in FIG. Is formed.

  Next, the state of the inner box 2 and the outer box 3 during the operation of the freezing foam box 1 according to the first embodiment will be described with reference to FIGS. 1 and 4.

  First, in the refrigeration / freezing process, as shown in FIG. 4, refrigeration management is required by using a plurality of inner boxes 2 of a freezing foam box 1 with their bottom plates 2a facing down. It is stored for a predetermined time in a large freezer with food such as meat and fish.

  Next, when loading from a large refrigerator to a refrigeration truck in the transportation process, first, an operator puts the outer box 3 on the opening surface of the inner box 2 as shown in FIGS. Further, as shown in FIG. 1 (c), the cover plate 3a of the outer box 3 is covered with the lower side and the bottom plate 2a of the inner box 2 is set on the upper side. As a result, the outer case 3 having a large size becomes the lower side, improving the transportability during loading, and reliably preventing the drip (liquid) from the food from flowing down. The refrigerated truck is a refrigerated vehicle that transports frozen goods, meat, frozen seafood, ice cream, fresh confectionery, dairy products, etc. while maintaining the freshness of the loaded cargo for a long time.

  As described above, in the freezing foam box 1 according to the first embodiment, the side plates 2b to 2e of the inner box 2 are formed with a plurality of cutout grooves 2f as vent holes. Therefore, even when a plurality of inner boxes 2 are stacked in a large refrigerator, a gap is formed between the internal space of the freezing foam box 1 and the outside air, and the temperature and humidity of the freezing foam box 1 are adjusted to the outside air. This can be easily adjusted. That is, the food refrigeration / freezing process can be performed in the large refrigerator using the inner box 2 of the freezing foam box 1.

  In addition, since the freezing foam box 1 has an excellent cold-retaining function, the food does not thaw even when a long period of time is required for loading into the freezing truck and loading from the freezing truck. In other words, the use of the freezing foam box 1 makes it possible to provide a packaging material in which food is easily cooled (frozen) in the refrigeration / freezing process and is difficult to thaw in the transport process. As a result, the cold chain is not interrupted, and it is possible to prevent food quality deterioration and disposal in the process of transporting the freezing foam box 1.

  Furthermore, since the freezing foam box 1 can consistently take charge of the food refrigeration / freezing process and the management / transportation process in large refrigerators, etc., it is no longer necessary to use cold storage packaging using conventional foamed polystyrene containers. , Work efficiency is improved. In addition, the conventionally required packing tools such as cardboard, wooden boxes, and metal pans are no longer required, and waste can be reduced and cost can be reduced.

  In addition, when packing refrigerated foods, such as vegetables and dairy products, in the foaming box 1 for freezing, you may bundle the cryogen (approximately 5 degreeC) which is not frozen. By doing so, it is possible to ship while maintaining a low temperature more reliably while suppressing a rapid temperature change.

(Modification 1)
A modification of the first embodiment will be described with reference to FIGS. In this modification 1, as shown in FIG.5 and FIG.6, the vent formed in the side plates 2b-2e of the inner box 2 of the freezing foam box 1 becomes the through-hole 2g. In addition, this through-hole 2g is formed using a cylinder at the time of manufacture of the freezing foam box 1. With this configuration, the first modification can achieve the same effects as those of the first embodiment.

(Modification 2)
A modification of the first embodiment will be described with reference to FIG. In the second modification, as shown in FIG. 7, a plurality of openings 2 h are formed in the bottom plate 2 a of the inner box 2 of the freezing foam box 1. With this configuration, in the second modification, in addition to the effect of the first embodiment, quick freezing can be performed.

(Modification 3)
A modification of the first embodiment will be described with reference to FIG. In the third modification example, as shown in FIG. 8, a handle portion 3 g that is a recessed portion is formed on the outer edge portion of the cover plate 3 a of the outer box 3 over a predetermined range. With this configuration, in the third modification, in addition to the effect of the first embodiment, the workability when the freezing foam box 1 is used can be further improved.

  The present invention is not limited to the configuration of the embodiment described above, and various modifications can be made without departing from the spirit of the invention. For example, the packing material packed in the freezing foam box 1 is not limited to food, and can be used to manage medicines, electronic parts, and the like at a constant temperature. Furthermore, although it demonstrated using the rectangular solid-shaped freezing foam box 1, it can apply also to polygonal shapes, such as a pentagon type and a hexagon.
