Problems solved by technology

However, such a box produced by compression molding needs to maintain a certain volume in order to contain the contents, so there is a problem that a lot of cost is required for storage and transportation.
[0004] On the contrary, the packaging boxes made of paper and corrugated paper are not only easy to make, but also can be unfolded when stored, and can be used through simple assembly when used. Therefore, it has the advantage of greatly reducing logistics costs, but , because the constituent material is paper material, so it is relatively fragile, and there is a problem that it cannot be used again, and there is also the problem that its heat preservation and cold preservation effect cannot reach the expected effect
[0005] In addition, the packaging boxes made of paper and corrugated paper are weak in water resistance. Therefore, when packing warm food or frozen food, moisture will appear in the packaging box due to temperature differences, making the packaging box unable to maintain out of shape, thus, there is a problem that it is not easy to carry

Abstract

The invention relates to a packaging box having heat-retaining and cold-retaining functions that comprises: a main box body consisting of a side-surface part in which side surfaces are formed by folding and securing four side walls so as to form a space in which contents can be held, a floor part which respectively extends from the bottom parts of the four side walls in such a way as to form a floor surface, and lid parts which respectively extend from the top parts of the four side walls in such a way as to cover the upper side of the side-surface part in openable and closable fashion; and foamed paper which protects the contents held inside the main box body from external shock, and is provided inside the main box body so as to maintain heat retention and cold retention.

Description

technical field [0001] The present invention relates to a packing box with heat preservation and cold preservation functions, more specifically, relates to a packing box with heat preservation and cold preservation functions which can safely and conveniently pack and manage contents that need heat preservation and cold preservation due to the possibility of deterioration and decay. The packaging box is a packaging box with heat preservation and cold preservation functions that can prevent moisture or moisture from penetrating into the box body. Background technique [0002] Generally speaking, in order to protect the contents from external impact and facilitate handling, most of the packaging boxes are made and used of several materials such as paper, corrugated paper, and plastic foam. [0003] When plastic foam is used to make the above-mentioned packing box, it can not only play the role of waterproof, heat preservation, and cold preservation, but also can protect the con...
