Cold storage box for food transport {COOLER BOX FOR CARRYING FOOD}

The present invention relates to a cold storage box, and more particularly, to optimize the quality of food, such as freshness in the process of shipping and transporting various foods that require refrigeration such as fruits, vegetables, and puddings from the manufacturing factory to the stores of the merchants. The present invention relates to a cold storage box for food transport that can be stored and maintained for a long time.

In recent years, the consumption of bread and desserts has been steadily increasing due to westernization, diversification, and busy daily life of the diet. So-called franchise-type sales methods that process and supply them to franchisees are the mainstream.

The characteristics of the bakery franchise are that the head office should develop products, services, know-how, etc. and ensure that the system is smoothly distributed and operated. Merchants are fresh and homogeneous products to consumers based on the products and systems developed by the head office. Should be provided.

However, in the related art, such contents as hot dogs, toasts, sandwiches, and vegetables and salads contained therein are primarily packaged in a packaging container, and then simply delivered in a plastic box and transported to a store using a refrigerator. Therefore, due to the characteristics of bread and vegetables sensitive to temperature, the freshness and quality such as the lack of moisture due to discoloration and drying occurred while being exposed to room temperature or easily contacted with external air during transportation and temporary storage.

In other words, in order to manufacture and sell high-quality foods with excellent taste and aroma as well as color, various conditions such as humidity, temperature, and time should be kept in optimum condition depending on the type. During the process, rancidity is promoted by bacteria or enzymes, which results in a decrease in the flavor and texture of the food, and even a serious problem of easily deteriorating on hot and hot days such as summer.

As a result, insulated boxes made of styrofoam materials were often used. However, these styrofoam boxes are formed in a unitary form, which makes them difficult to store when space is not used. However, there was a fatal flaw that caused the body to break when subjected to external force or load during the loading process.

In addition, if a part of the body is broken, it cannot be repaired or replaced partially, so the entire box must be discarded, resulting in enormous economic and environmental damage.

Accordingly, the present inventors have studied intensively for many years to develop a cold storage box for food transportation that can maintain the freshness of the food optimally in the process of shipping and transporting the food from the manufacturing plant to the store in consideration of the above-mentioned matters. As a result, the present invention was invented and completed.

Therefore, it is an object of the present invention to provide a cold storage box for food transport to prevent the freshness and commerciality is reduced during transportation and temporary storage according to the shipment of food.

And 400.

First, the bottom plate 100 is mounted on the bottom surface of the plastic box B while forming the bottom surface of the cold storage box. The bottom plate 100 has an opening that corresponds to a bottom surface of the plastic box having an approximately hexahedral shape and has a width corresponding to that of the bottom surface of the plastic box B. It is formed in a shape, and a plurality of mounting grooves 120 for stably mounting the refrigerant material (C) on the upper surface is formed.

Here, the refrigerant material (B) is a conventional one having a melting point of 0 ° C. or lower by sealing a refrigerant containing an absorbent polymer and water in a pack form, and keeping the storage space of the cold storage box at a low temperature for a predetermined time by the cold air. This can delay and prevent deterioration of the freshness and quality of the food stored in the storage space.

The side plate 200 is in close contact with the inner wall surface of the plastic box while forming the wall surface of the cold box, is formed in a rectangular plate shape having a width corresponding to the inner wall surface of the plastic box (B) to the peripheral surface of the bottom plate 100 It is erected along, and is composed of the front / rear and left / right side plates (200a, 200b, 200c, 200d) so as to minimize the volume as needed to form and assemble, respectively.

In addition, a plurality of clamp grooves 210 are formed at the upper edge of the side plate 200 such that the clamp 400 is coupled to form a horizontal plane, and the left and right sides of the front and rear side plates 200a and 200b are in close contact with each other. Stoppers 220 are formed on both sides of the side plates 200c and 200d to prevent the front and rear side plates 200a and 200b from moving inward.

In addition, the lower side of the front and rear side plates (200a, 200b) are respectively in contact with both side ends of the bottom plate 100 is formed with a locking step 230 to prevent the inside of the plastic box (B) to rotate have.

These front / rear and left / right side panels (200a, 200b, 200c, 200d) are easy to assemble with each other and can be easily folded or disassembled in some cases, greatly reducing their volume during storage and transportation due to unused use. Maximizing the efficiency of the loading space as well as to ensure the convenience of transport, if any one side plate 200 is broken can be quickly and simply repair and replace only the side plate.

The holder plate 300 is to maintain a state in which the food is stably stored without flow and departure during the transport process, between the side plates (200a, 200b, 200c, 200d) for smooth air circulation and stable seating of the food It is coupled to the bottom plate 100 at a predetermined interval, and a plurality of support holes 310 for inserting and fixing the food on the upper surface is formed.

The clamp 400 is to keep the bottom plate 100 and the side plate 200 is firmly coupled to the inner side of the plastic box (B), bending the metal plate in multiple stages and elastically deformed when subjected to an external force, When the external force is released, the restoring force is returned to its original state and is formed in the form of forceps that are continuously generated.

The clamp 400 is pushed downward from the upper portion of the plastic box (B) by being elastically wrapped at the same time and elastically surrounding the upper edge of the side plate 200 and the plastic box (B), the side plate 200 is a plastic box (B). It is possible to maintain a firmly coupled state without flow and departure from the), and when pulled upward, the clamping state is released to easily separate the bottom plate 100 and the side plate 200 from the plastic box (B). It becomes possible.

On the other hand, at the position corresponding to the clamp groove 210 of the side plate of the upper edge of the plastic box (B), the clamp 400 is similar to the edge of the clamp groove 210 of the side plate for stable lamination of other plastic boxes. A plurality of mounting grooves (BG) are formed to be coupled while forming a horizontal plane. Therefore, the clamp 400 is inserted into the clamp groove 210 of the side plate and the seating groove (BG) of the plastic box to form the same horizontal plane and vertical surface, thereby transporting and loading the cold storage box as shown in FIG. Multiple boxes can be stacked stably and easily in multiple stages, thereby further increasing the cold storage effect of the cold box.

Cold storage box having such a configuration is preferably formed in a rectangular parallelepiped structure, but is not limited to this may be changed to a variety of forms according to the plastic box and the specific use or design.

In addition, both the bottom plate 100 and the side plate 200 are EPP (foamed polypropylene), EPS (foamed polystyrene), EPE (foamed polyethylene) having characteristics such as excellent heat resistance, heat insulation, stability of specifications, flexibility and buffering properties. It can be formed of any one of the materials, but preferably formed by EPP (foamed polypropylene) can not only improve the good cold effect, but also improve durability, and can be recycled because the material is non-crosslinkable, less graphite and harmful There is no generation of gas, which facilitates waste disposal.

In addition, the cold storage box according to an embodiment of the present invention may obtain a food warming effect by excluding and removing the coolant (C) when the temperature of the atmosphere, such as winter, significantly drops due to the characteristics of the material.
