[Industrial applications]

 The present invention is a cold storage box for storing and transporting food, etc., delivery and collection in the home delivery business, and for the purpose of repeated use, etc. When re-cooling foods that have been exposed to outside air and raised in temperature, there is no need to change the normal work system, and a single box is sufficient for quick and efficient temperature recovery in a refrigerator-freezer or refrigerator-freezer container. Pre-cooling can be performed and quality and freshness can be maintained. Also, when the box is exposed to the outside air, such as in the case of delivery, the present invention relates to a cool box for the purpose of maintaining the temperature by rotating the lid and fitting it tightly.

[0002]

[Prior art]

 In the past, Styrofoam boxes have been used for shipping and delivery of frozen and refrigerated foods and for return boxes (delivery and collection, repeated use) in the home delivery business. In this operation, when loading for transportation or storage, due to its structure, it has been sealed and then stored in a refrigerator or transported by a refrigerator car. As a result, the flow of cold air into the box was cut off, and the purpose of pre-cooling could not be sufficiently achieved. This pre-cooling is important for food temperature control.However, comparing the cooling performance of a conventional box with a lid closed tightly and the cooling performance with the cool air flowing without the lid, the box once exposed to normal temperature In order to recover the food temperature inside to the original temperature (set temperature of the refrigerator), it is obvious that anyone without the lid is more advantageous and effective. For example, in the home delivery business, food and other products are taken out from commercial freezer refrigerators and sorted and picked. At that time, the workplace is at room temperature or in a higher temperature environment (about 15 to 18 ° C) than the freezer refrigerator. The food must be retained for a long time, and the food temperature rises over the length of the residence time. For this reason, after sorting, cool boxes containing foods are loaded on a trolley and pre-cooled again in a refrigerator. The cooling time varies depending on the operation, but it is impossible to return to the set temperature immediately because the conventional box has already been closed and closed at the loading stage. However, it was unavoidable that priority was given to operational convenience. The same is true for transportation by a refrigerated container. In reality, the contradiction of cooling the product with the temperature raised in a sealed state was openly performed, but the idea of performing cooling and pre-cooling in a single cooling box could not be considered at all. Did not. On the other hand, aside from using the Styrofoam box once (one-way use), if the Styrofoam box is repeatedly used more than ten times as a box through which the Styrofoam box is used, such as in the case of home delivery, the Styrofoam box is worn due to its material. Despite being intense and easy to contaminate, it could not be machine-washed, nor could it be washed sufficiently by hand, leaving meat juices and residues in the food, resulting in fungi and mold, causing serious hygiene problems.

[0003]

[Means for Solving the Problems]

 In order to provide the cool box with the function of keeping cool and pre-cooling, it is necessary to enable two functions, that is, the main body and the lid are airtight and open so that air can flow. In order to solve this problem, the present invention devises an uneven arrangement for the fitting of the upper part of the main body and the lower part of the lid. The lower concave / convex structure and arrangement were adopted, and the fitting structure was such that the tapered fitting portion was sealed.

Conversely, when pre-cooling is desired, the lid is rotated by 180 ° horizontally with respect to the main body, so that the fitting projections at the four corners of the main body and the fitting projections at the four corners of the lid interfere with each other, and the gap in the outside air circulation is reduced. It has a structure that can be used.

[0005] In addition, in the case of cooling or pre-cooling, a plurality of the same cooling boxes are stacked on a lid, and one box has operational options.

[0006] The material is composed of a body and a lid in which a molded polypropylene foam having a thickness of about 12 mm is sandwiched and integrated with an outer box and an inner box each molded of a polypropylene resin of about 1.5 mm. Concavo-convex and tapered parts for cooling and pre-cooling were arranged. The reason why the three materials are unified with polypropylene is to facilitate recycling. The reason why the thickness was reduced to 15 mm was because women tended to engage in home delivery work and aimed to reduce the weight. The thickness and size of the cool box can be changed and manufactured without changing the basic structure, depending on the amount and weight of the box.

[0007] The external appearance is a one-third tapered storage type in order to reduce the space for storage and transportation of empty boxes, and a handle and a storage support portion are arranged on the main body. The storage support section is provided because, when empty boxes are stored and loaded and stored in a large freezer refrigerator, a gap for cooling air is secured so that the cool box itself can be cooled.

[0008]

[Action]

 A pre-cooling gap that allows the cool air to flow through the lid when the food is taken out of the freezer refrigerator for various operations and exposed to a higher temperature range or at room temperature, and the temperature of the food has risen, or the food after production is cooled and stored or transported. Efficient cooling can be achieved in a short time by using a cool box in a state.

[0009] In the final purpose of delivery and transportation at room temperature, a cold storage material or a dry ice storage medium is put in, and the lid is rotated 180 ° horizontally and put in a cold storage closed fitting state. It becomes a cool box.

[0010] In the case of pre-cooling or insulated, a plurality of insulated boxes can be stacked, so that there is no need to change the work procedure and to change the bogies and auxiliary equipment.

[0011] Furthermore, hygiene can be controlled because cleaning can be performed.

Since the materials are all the same, recycling is easy.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, the upper four corners of (A main body) have (D main body fitting convex portion), (E main body fitting concave portion), and six (F main body fitting taper portions). At the lower four corners of the (A1 lid), there are (G lid fitting convex part), (H lid fitting concave part) and six (I lid fitting taper part) corresponding to the main body. . When the lid is closed in this state, the fitting concave and convex portions of the main body and the lid fit without interfering with each other, and the refrigerator is closed and sealed as shown in FIGS. 3, 4, and 10. Also, FIG. 2 shows that the (A1 lid) is rotated by 180 ° horizontally with respect to the main body, and (D main body fitting convex portion) and (G lid fitting convex portion) interfere with each other. This indicates that a pre-cooling structure in which cold air easily circulates is formed on the six surfaces of the lid (J outside air circulation gap).

Referring to FIGS. 6 and 7, the sealing structure of the main body and the lid will be described in more detail. At the upper part of (A main body) in FIG. 6, (D main body fitting convex portion) for sealing fit, (E main body fitting concave portion), and (F main body fitting taper portion) are formed. A lid is also provided to facilitate removal of the lid (one lid recess). On the other hand, in the lower part of (A1 lid) in FIG. 7, (G lid fitting convex part), (H lid fitting concave part), and (I lid fitting taper part) are formed. When the lid is placed on the main body, the main body, the concave and convex portions and the tapered portion of the lid are fitted to each other to form a sealed state. For example, (H lid fitting concave part) fits into (D main body fitting convex part), and (F main body fitting taper part) and (I lid fitting taper part) are rubbed. The cross section in FIG. 10 shows the structure, and the state between the main body and the lid is (C cold-sealing tight fitting).

On the other hand, when the same (A1 lid) rotated horizontally by 180 ° in FIG. 8 is put on the main body in FIG. 6, the (D main body fitting projection) and the (G lid fitting projection) interfere with each other. Therefore, there is a gap between (E body fitting concave portion) and (H lid fitting concave portion) and (F body fitting taper portion) and (I lid fitting taper portion), and cool air is discharged from all four sides. It will be distributed inside the main unit. FIG. 9 is a cross-sectional view showing this state, and has (J outside air flow gap).

FIG. 9 is a sectional view showing pre-cooling loading, and FIG. 10 is a sectional view showing cold-holding loading. The upper part of the (A1 lid) has the plan view of FIG. 5 and the structures of (7 loading lid projections) and (8 loading lid recesses) of FIGS. 9 and 10, and the lower part of the cool box main body enters into this. There is no gap. The lid structure is also symmetrical, so multiple boxes can be loaded. By adopting this structure, it is possible to carry out pre-cooling in a state where there is a gap, as well as to carry out pre-cooling while keeping cool. If this is considered in operation, for example, if it is desired to freeze in a freezer, it can be pre-cooled, and refrigerated items can be kept in a cool state so that they can be stored in the freezer in a complex manner. In the case of emergency or when there is no refrigerator, frozen items can be frozen in a freezer, and refrigerated items that you do not want to freeze can be refrigerated as much as possible by keeping them cool and sealed. This method is a revolutionary management method in the field of distribution and equipment of frozen and refrigerated goods.

The material and structure of the cool box of the present invention will be described in detail with reference to FIGS. 9 and 10. The material of the main body and the lid, (9 outer boxes) and (10 inner boxes) are both 1,5 mm thick polypropylene, and (11 heat insulating material) are also integrated using 12 mm thick polypropylene foam. Things. The reason for this is to facilitate recycling. The structure is a one-third taper storage type in order to increase the empty box collection / transportation efficiency and storage efficiency of (A body) and store it as shown in FIG. The main unit is also provided with (12 reinforcing ribs at the bottom of the main unit) and (13 vertical parts) at the top to allow for conveyor conveyance. It is provided. A (two handle recess) is provided on the side of the box. In consideration of the weight of women, the total weight of the main body and lid is approximately 1,500 g, achieving an incredible weight reduction. The cold storage box of the present invention has sufficient cooling performance with this material composition and structure.

[0018] Because it is a plastic product, it is remarkably hard to break as compared with a styrofoam box in which abrasion waste is frequently replaced, which leads to resource saving.

In addition, the washing, sterilization and sterilization by an automatic washing / drying machine can be performed, so that it is extremely sanitary. The cool box according to the present invention is suitable for both temperature control and hygiene control.

[0020]

[Effect of the invention]

 Since the present invention has the structure and configuration as described above, the following effects can be obtained.

The ability to perform the two functions of pre-cooling and cold preservation according to claim 1 means that, for example, during sorting work in the home delivery business, the preservation box is pre-cooled, and the pre-cooling storage by a large freezer / refrigerator is performed in the next step. Migration can be performed as it is, and work can be performed smoothly. Also, at the time of shipment, it is simple and rational because the cold storage box only needs to be filled with dry ice or cold storage material of the cooling medium, and the cold storage box is changed to the cold storage function state. When transporting from the pre-cooled storage to the refrigerated container again, it is loaded in the pre-cooled state as it is and can be cooled during transportation, so it is efficient and wasteless.

[0022] With the structure of claim 2, there is a contradiction that, like the operation with a conventional styrofoam box, the user wants to cool the food but closes it with a lid, makes it hard to cool, and puts it in a refrigerator. Eliminating this will shorten the pre-cooling time and allow efficient cooling, which will greatly contribute to maintaining freshness.

The same lid can be used in both the cold-preserving state and the pre-cooling state, and when a plurality of cold-preserving boxes are placed on the lid, for example, a food or the like to be greatly cooled is stored in a pre-cooled state with a gap and stored. Food items that you do not want to cool too much can be stored in a sealed cold storage container that can be sealed, so that you can store both frozen and refrigerated items in the freezer for operational convenience, rotation, and emergency situations.

Since the material is resin, it can be washed and is strong and clean. It is extremely hygienic and economical when compared to conventional styrofoam boxes, which are often worn, cannot be washed, are frequently replaced, and are full of fungi and mold. In addition, the ability to pre-cool the cool box itself even when loading and storing empty boxes is revolutionary and efficient, and can further contribute to temperature control of foods and the like.

[0025] Lightweight is very important today as the number of female workers is increasing, and it can expand female employment in this field.

The fact that the insulated boxes according to the present invention are all made of the same material facilitates recycling and greatly contributes to environmental conservation.
