Description

Assembly type insulation box}

The present invention relates to an insulated box for packaging fresh food, thermal insulation items, medicines, etc., and more specifically, to a prefabricated box that is inserted into the box body so that the entire inner surface is covered with an insulating pad, and can be easily assembled and disassembled. It's about insulated boxes.

In general, insulated boxes are used to package fresh foods such as fish, meat, and various agricultural and marine products, items that need to be kept warm, and medicines.

Such conventional insulated boxes were mainly made of Styrofoam.

Although these insulated boxes made of Styrofoam have excellent insulation effects for packaged goods, it is not easy to manufacture them in various sizes, and it is difficult to manufacture them compactly due to the thickness of the Styrofoam material. As a result, they are bulky when stored or transported. There was a problem with poor space utilization.

On the other hand, boxes made of paper are easy to manufacture in various sizes and compact, and have a small volume when stored or transported, providing excellent space utilization, but there is a problem in that the insulation effect is greatly reduced.

In order to increase the insulation effect while taking advantage of the advantages of such a paper box, the box is manufactured by thickening the paper material or using a multi-layered material such as corrugated cardboard, and attaching an insulating sheet layer to the inner side of the box. This was done to further improve the insulation effect.

However, since the above-mentioned paper-based insulating box is used by attaching only a single insulating sheet layer to the inner side of the box, there is a limit to improving the insulating effect by the insulating sheet layer, and in addition to the insulating function, it is resistant to external shocks like a Styrofoam insulating box. There was a problem that it did not have a protection function.

In addition, since the above-described paper-based insulation box is manufactured as a whole with an insulation sheet layer attached to the inside, the manufacturing process is not only complicated, but also the difficulty of disposing of the paper and the insulation sheet layer separately when disposing of the insulation sheet layer. There was an uneconomical problem in that it could not be separated and reused.
