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 provided with a double locking structure of a detachable coupling structure and a lock coupling structure.

The box for packing the goods is generally manufactured in the shape of a rectangular parallelepiped, and if necessary, the goods are put inside the box together with a buffer or the like.

As such a box for packaging, there is a folded cardboard box made of corrugated cardboard or a cardboard-shaped synthetic resin. The type in which both the bottom and the top are taped with foil staves is the simplest and does not require a separate special cutting process, so it is widely used for packaging of mass-produced products.

The above-described conventional packaging box is provided with a locking means to prevent arbitrary opening during delivery, but the lock structure is insufficient, so that the delivery person may see the items inside the box or eat food in the case of food, so improvement measures are required for this.

In order to solve this problem, a box structure that cannot be opened unless the packaging box is opened, but in this case, since the box cannot be reused, a countermeasure is also required.

On the other hand, the conventional packaging box has a disadvantage that a separate bonding process and/or a taping operation must be performed on the upper side and the lower side twice. To solve this, various prefabricated boxes have been proposed in the related art.

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

In recent years, the number of businesses operating through internet shopping malls is increasing, and thus the number of small and medium-sized businesses and individual businesses handling small parcels is increasing.

Accordingly, there is an increasing need for a structure of an eco-friendly packaging box while satisfying the desired solid packaging strength without a separate taping operation, and at the same time reducing the cost required for packaging.

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

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