Description

{JUNCTIONLESS COLLAPSIBLE ASSEMBLY PACKING BOX}

The present invention relates to a non-bonded, foldable, prefabricated packaging box, and more particularly to a foldable packaging box which is capable of achieving a three-dimensional structure (assembly) of a box by omitting a series of edge bonding processes and also serving as a tray or a bowl The present invention relates to a non-bonded folding and packaging box.

The packaging industry in Korea is required to secure both the manufacturing technology of packaging boxes and the aesthetics that can meet various needs of consumers, which can occupy an advantage in competition between enterprises in the global era of infinite competition system .

The packaging box (hereinafter referred to as a "packaging box") is a means for storing and distributing various articles and carrying them in an internal storage space. Traditionally, , But the past packing box focused on basic functions such as storing or protecting necessities on the premise of bartering.

On the other hand, today it is defined as an element of the merchandising policy that is fundamentally related to consumer choice, and it is necessary to confirm the identity of the product beyond the design for safe use and storage, .

Currently available packaging materials include paper (paper), wood, glass, and synthetic resin (plastic), but the most commonly used material is paper. In other words, it is not an exaggeration to say that the packaging box is the most used paper machine. Paper jigs are generally known as paper containers, such as paper boxes and cardboard boxes. Recently, paper jugs have been used as main materials, but various composite materials such as synthetic resin films and gold foil have been used together.

It has the advantage that it can be flexibly bent, cut, and connected with each other and can form freely. They also have the advantage of being lightweight, easy to process, cheap, robust, safe and printable. In recent years, the use of prefabricated packaging boxes, which are folded at the factory to maximize the efficiency of transportation, or are provided to the user as an unfolded structure, are increasing in frequency.

However, as described above, in the case of being folded and made small or being provided to the user in the form of a deployed structure, it is troublesome to carry out an assembling process for completing the three-dimensional structure, and a structural improvement .

In addition, due to the nature of the paper material, there is a disadvantage in that the strength for maintaining the shape of the box is weak, unlike that made of materials such as wood, glass, and plastic, when storing a somewhat heavy article such as cosmetics, Technical improvements are also required.

Hereinafter, a general structure of a prefabricated packaging box (hereinafter referred to as a "prefabricated packaging box"), which is disclosed in Korean Registered Utility Model No. 20-0339384, will be described.

FIG. 1 is an exploded view of a prefabricated packaging box according to the prior art. In the conventional prefabricated packaging box, as shown in FIG. 1, a handle 909 is formed so as to be movable in the shape of a rectangular parallelepiped, The bottom surface 901 is integrally formed on the front and rear surfaces 902 and 903 and the lower ends of the left and right surfaces 904 and 905 and then a fold line 906 is provided at each of the boundary lines.

A trapezoidal fitting portion 907 is integrally formed on the upper ends of the left and right upper and lower surfaces 904 and 905 and a fitting groove 908 is formed at the center of the fitting portion 907 A knob groove 910 is formed integrally with the knob 909 at the upper end of the front and rear surfaces 902 and 903 and the fold line 906 is formed in the direction of the knurling of the knob 909, And an insertion / removal groove 911 is formed on both sides of the upper end of the handle 909.

This makes it possible to store various articles in the inner space formed by folding the front and rear surfaces 902 and 903 and the left and right surfaces 904 and 905 to form a rectangular parallelepiped. So that portable movement can be facilitated.

However, since the three-dimensional structure of the packaging box can be completed if the connecting blade at the end of the rear surface 903 and the edge of the seating surface 904 are overlapped with each other with an adhesive or a stapler, (Edge joining process) must be performed. For this reason, there has been a problem of labor cost incurred due to delay in the packaging box manufacturing process and employment of process execution workers.

Further, the bottom surface 901 is formed only when a plurality of bottom surfaces 901 extending from the lower side of the front and rear surfaces 902 and 903 are assembled to face each other. It has been pointed out as a cause of loss and loss of stored articles such as leakage of articles housed in an internal space, in particular, packaged foods and the like.
