Description

Packing box with insulation and cooling function}

The present invention relates to a packaging box with thermal and cold insulation functions, and more specifically, a bottom plate, front and rear side plates, left and right side plates, front upper cover plate, left and right front mounting plates, left and right rear mounting plates, left and right reinforcing plates, It consists of one piece including the left and right fitting fixing plates, the rear upper cover plate, and the front cover plate, and the left and right rough wing plates are applied to both sides of the front cover plate. After assembly through folding for packaging the product, taping is performed on the lower part or sides. Without this, there is no gap in itself, and through this, unlike before, it prevents moisture or oil from leaking through gaps in the bottom or sides, while at the same time maximizing heat insulation or cold insulation efficiency through a structure that eliminates gaps. One site including the plate, front and rear side plates, left and right side plates, front upper cover plate, left and right front mounting plates, left and right rear mounting plates, left and right reinforcing plates, left and right mounting fixing plates, rear upper cover plate, and front cover plate. When assembling a box, a wave-shaped corrugation is further attached and molded on one side facing the inside, so that oil or moisture from oily or frozen packaged goods is received into the ribs and the packaged goods are supported on the acid part, allowing oil or moisture to come into contact with the packaged goods. This can reliably prevent the packaged goods from becoming damp, and by applying a perforation line to the front cover plate and attaching means in the form of a strip to one side of the front and back plates placed on the front side, the final finish is achieved when assembling the box. It relates to a packaging box that has heat-insulating and cold-insulating functions that can be easily opened through an attachment means and at the same time cut into a strip shape through a perforation line when opening.

In general, packaging boxes manufactured to store or transport contents such as agricultural products, marine products, and livestock products that require heat and cold insulation are mostly made of various materials such as paper, cardboard, and Styrofoam.

When such a packaging box is made of Styrofoam, it not only provides waterproofing, thermal insulation, and cold insulation effects, but also protects the contents stored inside from shocks applied from the outside. However, the molded box itself maintains a certain volume to contain the contents. Since it was compression molded to do so, there was a problem in that it cost a lot of money to store and transport.

On the other hand, packaging boxes made of paper and cardboard are easy to manufacture and can be stored in an unfolded, stacked state and then simply assembled when in use, which has the advantage of greatly reducing logistics costs, but its constituent material is made of paper. Because of this, the waterproofness is greatly reduced, and the warming and cooling effects do not reach the expected level, and at the same time, there is a problem in that the contents stored inside cannot be properly protected from external shock.

Moreover, packaging boxes made of paper and cardboard have the problem of gaps forming in the bottom or sides after assembly is completed by folding. Accordingly, the process of sealing the gaps through attachment or taping to the bottom or sides is essential. In addition, there was a problem in which moisture or oil inside the box leaked to the outside through gaps in the bottom or sides.

Therefore, after assembling the product by folding it for packaging, there is no gap in the lower part or the side without any taping work. This prevents moisture, oil, etc. from leaking through the gap in the lower part or the side, unlike before, and also prevents the gap. It is possible to maximize the efficiency of thermal or cold insulation through a structure that eliminates heat insulation, while maintaining product quality while efficiently insulating or cooling items that require heat or cold insulation. It is also environmentally friendly by allowing separate disposal for recycling. There is a need for research and development on packaging boxes with improved thermal and cold insulation functions.
