Description

Packing box {PACKING BOX}

The present invention relates to a packaging box, and more particularly, to an inner box that can be inserted into an outer box, including an accommodation space for receiving a packaged object.

Packaging boxes can be used in a variety of fields, and are particularly used for packaging electronic device products. For example, in the case of a mobile phone, the body of the mobile phone, a battery, an electric wire, a charger, and the like are packaged and sold in a packing box. Therefore, the packaging box may be divided into an inner box for accommodating a mobile phone and an outer box surrounding the inner box and displaying a trademark.

However, conventional packaging boxes may generally be made of plastic or paper. Packaging boxes made of plastic materials are easy to manufacture in a complex shape, convenient to use in the workplace, but because they are not environmentally friendly and inconvenient to recycle, recently used a lot of packaging boxes made of cardboard.

Such packaging boxes can be assembled in a deployed state to a finished state. Therefore, the packaging box can be delivered to the business site in a deployed state, and can be assembled and used directly at the business site for convenient storage and transportation. However, a packaging box made of a conventional corrugated cardboard is complicated to assemble and takes a long time in the workplace, and is somewhat inconvenient because the assembly process is difficult. In addition, even after the packaging box is assembled, the binding state is not sure, and thus the binding state may be dismantled without maintaining the structure by external impact.

Therefore, one object of the present invention for solving the above problems of the present invention is to provide a packaging box having a simple assembly method and stable structure.

In addition, another object of the present invention is to provide a packaging box for easy transportation and storage.

Still another object of the present invention is to provide a packaging box that provides a storage space suitable for accommodating a plurality of packages.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the packaging box has a bottom plate, the main side wall portion, the outer side plate portion, the connecting piece, the adhesive piece and the intermediate side wall portion.

The bottom plate forms the bottom of the packing box, and the main side wall portion and the outer side plate portion are connected to each corner of the bottom plate through a bend line. The main side wall portion is connected to both opposite edges of the bottom plate via a bend line and forms a side wall. The outer side plate portion is connected to one edge of the bottom plate via a bend line and forms one side wall of the bottom plate. Thus, an accommodating space for accommodating the packaged object can be formed on the bottom plate by the bottom plate, the main side wall portion and the outer side plate. The middle sidewall portion is connected to the outer side plate via a bend line, and includes a first intermediate side plate bent into the adhesive piece and the connecting piece, and the connecting piece may be connected to the side edge of the main sidewall portion by a bend line. In addition, the adhesive piece may be connected to the connecting piece via a slanted fold line, and may be bonded to the inner surface of the outer side plate portion. Thus, the main side wall portion can be bent flat on the bottom plate along the fold line, and can be bent perpendicularly to the bottom plate along the fold line. In addition, since the first intermediate side plate is bent over and in close contact with the inclination fold line, the main sidewall portion may be prevented from being bent over the bottom plate along the inclination fold line to maintain the structure of the side wall.

The conventional packing box is formed with an oblique fold line on the side wall portion forming a side wall at each corner of the bottom plate. Therefore, the side plate can be bent flat on the bottom plate to reduce the volume, and can be used to make the side wall by bending the side plate perpendicular to the bottom plate directly in the industrial field. However, the assembled packaging box is also difficult to maintain the structure because the side wall is folded flat on the bottom plate along the oblique fold line when subjected to some force from the outside. As a result, an accommodation space for accommodating the packaged object is not formed.

However, in the packaging box according to the present invention, since the main side wall portion is bonded to the inner surface of the outer side plate by the connecting piece and the adhesive piece by the outer side plate, and the first intermediate side plate is bent thereon, the first intermediate side plate is the inclined fold line that is the boundary between the connecting piece and the adhesive piece. It is fixed to the bottom plate adjacent to it. Thus, the main side wall portion is bent over the bottom plate by the inclination fold line, and the first side wall portion is prevented from being bent along the inclination fold line so that the main side wall portion is always perpendicular to the bottom plate. In addition, the assembling process is also simple since the main side wall is automatically fixed to the bottom plate when the first intermediate plate is fixed to the bottom plate.

Alternatively, the packing box has a bottom plate, a main side wall portion, an outer side plate portion and an intermediate side wall portion. The bottom plate includes an inner partition plate that is cut out to protrude upwards. Therefore, the inner partition plate protrudes on the bottom plate and serves to partition the inner space. The main side wall portion is connected to both opposite edges of the bottom plate via a bend line, and the outer side plate portion is connected to one edge of the bottom plate. In addition, the first intermediate bottom plate and the first intermediate bottom plate connected to the outer side plate part and bent to the inner side of the outer side plate part, the first intermediate plate connected to the first intermediate side plate, and the inner slit grooves corresponding to the inner partition plate are formed. And a second intermediate side plate connected to the intermediate bottom plate.

Therefore, the packaging box can accommodate a variety of products by partitioning a plurality of internal spaces by the first intermediate bottom plate having an inner partition plate and an inner slit groove formed in the bottom plate. Therefore, the packaging box does not require a separate partition plate, so that the corrugated sheet (sheet) is required to reduce the manufacturing cost. In addition, the inner partition plate is bound to the inner slit groove can be maintained in a stable structure.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.
