Description

Paper Box Having Sturdy And Easy Assembly

The present invention relates to a paper box, and more particularly, to a paper box including a sturdy and simple assembly structure.

In general, a packaging box serves to store and store the contents in an internal storage space or to protect the contents during delivery. In addition, the packaging box also plays a role in storing and packaging gifts in the internal storage space.

1 shows a packaging box according to the prior art.

In the case of the packaging box according to the prior art, a content protection structure is additionally mounted therein to protect the contents stored in the internal storage space. In addition, it is manufactured in a structure that can be assembled by being separated into upper and lower parts to seal the inner storage space of the packaging box.

However, in the case of the packaging box according to the prior art, there is a problem in that the upper structure and the lower structure must be separately manufactured.

To solve this problem, a packaging box consisting of a single structure has been developed. However, in the case of a packaging box composed of a single structure, it is made of a single-layer paper material and is easily deformed by an external impact, and thus has a problem that the contents stored therein cannot be safely protected.

In addition, the packaging box consisting of a single structure according to the prior art has a complex structure in order to form a storage space that can accommodate the contents therein, and also have a configuration that can seal the storage space. For this reason, there is a problem in that a large number of pieces of raw materials are generated in the process of cutting the development view of the packaging box from raw materials, resulting in severe waste of raw materials.

Therefore, there is a need for a technique capable of solving the above-mentioned problems according to the prior art.
