Description

Packing box that can be packed without tape

The present invention relates to a packaging box that can be packaged without a tape, and more particularly, includes a side plate, an upper plate, and a lower plate, but the free end corners of the upper and lower plates are cut obliquely to form an assembly guide inclined surface, and the upper and lower plates Fitting corners are formed at the free end corners of the other side of the upper and lower plates, and a structure in which fitting sloping holes are formed in the longitudinal center of the upper and lower plates is applied, making it easy to manufacture with a simple structure consisting of side plates and upper and lower plates. , A plurality of upper and lower plates are stacked alternately on each other, overlapping each other, to seal the upper and lower parts, and then fasten the exposed corners to the outside. Tape including double-sided tape, adhesive, string, etc. It is easily assembled in a hexahedral box shape without the need for sealing means so that quick packaging and sealing work can be done, while separating the fitting corners from the fitting inclined holes of the upper and lower plates, making it easy to open work after packaging and sealing work It relates to a packaging box that can be packed without a tape so that it can be made.

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 to deliver predetermined contents 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 (Korea Utility Model Publication No. 1999-000502, published on January 15, 1999.).

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

rear side panels

10 and 11 are bent so that the front and

rear side panels

10 and 11 are erected around the bottom panel 1, 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 alternately coupled to make them 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 upper 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 disassembled, 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 must be fixed with glue, bond, string, tape, etc. after accommodating the contents in the box.

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, it has a simple structure and is easy to manufacture, and at the same time, it is easily assembled without sealing means such as tape, adhesive, string, etc. There is a need for research and development on a packaging box that can be easily made.
