After assembling the upper and lower parts to seal the upper and lower parts while overlapping each other, the exposed edges are fitted and fixed to form a hexahedral box shape without sealing means such as double-sided tape, adhesive, or string, for quick packaging and The sealing operation can be made, and while separating the fitting edge from the fitting inclined cutout of the upper and lower plates, it is possible to easily perform the opening operation after packaging and sealing work, while from the edge of the edge of the fitting edge for the upper and lower plates. By applying an incision structure, not a groove or hole, to the interlocking cut-off formed on both sides at a certain distance and the fitting inclined incision for the upper and lower plates to be caught and supported, the fitting state is more stably supported when the fitting edge is fitted. It relates to a packaging box that can be packaged without a tape so that the maintenance of the assembled state can be made more firmly.

In general, a box is used to deliver goods or the like by mail. In this case, the user submits to the post office using a predetermined box prescribed by the post office so that the contents are not damaged or lost.

In addition, the packaging box is used when a predetermined content is delivered by mail, and a parcel box of a predetermined size is purchased and delivered. .

1 is an exemplary view showing a packaging box according to the prior art.

On the other hand, the packaging box according to the prior art is presented as a postal parcel box as shown in Patent Document 1 (Korean Utility Model Publication No. 1999-000502, published on January 15, 1999.).

As shown in FIG. 1, the configuration of the postal parcel box applied to the conventional packaging box as described above is bent so that the front and

rear side panels

10 and 11 are erected around the bottom panel 1, and their auxiliary wings (12) is also bent.

And the first and second

auxiliary panels

13 and 14 extending from one side of the front and

rear side panels

10 and 11 are bent to overlap, and the first slot 13a and the second slot 14a are bent. ) are alternately combined to make them stand upright, and the third and fourth

auxiliary panels

16 and 17 extending from the other side of the front and

rear side panels

10 and 11 are bent to overlap, and the bent piece 18 ) is bent so that the third and fourth

auxiliary panels

16 and 17 are maintained in an upright state.

In addition, the right side panel 2 is erected toward the upright first and second

auxiliary panels

13 and 14, and the first top panel 3 extending from the right side panel 2 is bent to cut one side of the upper part. cover, and upright the left side panel 4 toward the third and fourth

auxiliary panels

16 and 17, and bending the second upper panel 5 extending from the left side panel 4 to to cover the whole.

Then, the fixing piece 7 of the second upper panel 5 is inserted into the cut-out hole of the first upper panel 3 and fixed, but the bent portion of the fixing piece 7 is the cut-out line 8 of the cut-out hole 6 . ), the coupling force is large around the fixing point 9, and when the assembled parcel box is dismantled, the second upper panel 5 is opened and folded by pulling the handle 19 in the folded state. Disassembly can be done easily.

However, the conventional box as described above has a problem in that the contents are accommodated in the box and then fixed with glue, bond, string, tape, or the like.

In other words, large marts such as E-Mart, Homeplus, and Lotte Mart have provided packaging space with paper boxes, tapes and strings so that customers can directly pack their purchased products, and from January 1, 2020, large-scale marts Tapes and strings have disappeared from the self-contained packaging stand.

As mentioned above, the autonomous packaging stand has not disappeared, but the reflection of the paper box is maintained because it is pointed out that consumer inconvenience may increase if the paper box is also removed.

That is, the problem of not providing tapes or strings in large marts as described above is to prevent environmental pollution caused by the use of plastic tapes or strings. A packaging box that can be easily repackaged without a string or the like is required.

In addition, the conventional box as described above has a disadvantage in that a plurality of fixing pieces or incision holes must be installed, so that the structure is complicated and the assembly process is increased.

Therefore, the simple structure makes it easy to manufacture, and at the same time, it is easily assembled without sealing means such as tapes, adhesives, strings, etc. There is a need for research and development on a packaging box that can be easily made.
