Description

Eco-friendly packaging box with double locking structure {ECO FRIENDLY PACKAGING BOX HAVING A DOUBLE ROCKING STRUCTURE}

The present invention relates to a packaging box, and more particularly, to an eco-friendly packaging box having a double locking structure of a detachable coupling structure and a locking coupling structure.

A box for packaging an article is generally made in the shape of a rectangular parallelepiped housing, and if necessary, the article is put inside the box with a buffer or the like.

Widely used as such a packaging box includes a folding cardboard box made of corrugated cardboard or cardboard-shaped synthetic resin. The type, in which both the bottom and top are taped with box tape, is the simplest and does not require a special cutting process, so it is widely used for packaging of mass-produced products.

In the conventional packaging box described above, a locking means is provided to prevent arbitrary opening during delivery, but the lock structure is insufficient, so that the delivery person sees the goods inside the box or eats food in some cases, so improvement measures are required.

In order to solve this problem, a box structure that cannot be opened unless the packaging box is opened is disclosed.

On the other hand, the conventional packaging box has a disadvantage that a separate bonding process and/or taping operation must be performed over the upper and lower surfaces secondary. In order to solve this, various prefabricated boxes have been proposed in the prior art.

In such a conventional one-sided prefabricated packaging box, a separate bonding process or taping operation is required to complete the top surface, so there is a disadvantage in that related costs such as cost and manpower increase.

In recent years, the number of cases of conducting business through an Internet shopping mall is increasing, and the number of small and medium-sized enterprises or individual operators handling small parcels is increasing.

Accordingly, there is an increasing need for a structure of an environmentally friendly packaging box that can reduce the cost required for packaging while satisfying a desired strong packaging strength without a separate taping operation.

In addition, even in large-scale production lines, there is a need for an improvement measure that can finish packaging by simply bending without a separate taping or stapling process.

The above-described technical configuration is a background for helping the understanding of the present invention, and does not mean a conventional technique widely known in the art to which the present invention pertains.
