Description

Corrugated cardboard packaging box

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated cardboard packaging box having a corrugated cardboard pallet part and a corrugated cardboard box part, and more particularly, to a corrugated cardboard packaging box and a method of assembling the corrugated cardboard packaging box, wherein the fork insertion opening is a space created by a difference in height between folded lines of left and right flaps and folded lines .

Conventionally, a pallet for use with a packaging box for unloading by a forklift was generally a wooden pallet or a plastic pallet. However, when exporting using a wooden pallet, the wooden pallet had to be fumigated at a predetermined temperature for a predetermined period of time in order to relieve the pests hidden in the wood. Therefore, a variety of corrugated cardboard pallets are being developed which are free from the hiding of insects.

The conventional corrugated cardboard packaging box is composed of a corrugated cardboard box body and a corrugated cardboard pallet installed on the bottom of the corrugated cardboard box body, as described in Patent Document 1, for example.

As such, the corrugated pallet is exposed to the outside, so that when the fork is inserted, the beam of the corrugated pallet can be torn down or collapsed.

In addition, the beam of the corrugated pallet may collapse or fall when pushing the corrugated cardboard box.

In addition, although the corrugated cardboard box body is integrally formed on the corrugated cardboard pallet, the corrugated cardboard box may be detached from the corrugated cardboard pallet after the corrugated cardboard box is carried by the forklift and the joint is broken.

In addition, when the corrugated cardboard packing box is stacked, the vertical rolled steel is directly transferred to the upper plate of the corrugated pallet, and the thickness of the upper plate is relatively thick, so that the steel plate can withstand the vertical rolled steel without being distorted. .

To solve such a problem, a conventional corrugated cardboard packaging box has been proposed in Patent Document 2.

The corrugated cardboard packaging box 1 has a cardboard box body 2 and a corrugated cardboard pallet 12 as shown in Fig. The corrugated box body 2 is composed of a corrugated cardboard lid 3 and a corrugated cardboard shell frame 4 which can be folded.

The corrugated shell frame 4 is formed in a square pillar shape having openings at the top and bottom, and is formed by joining a pair of shell frame members (not shown) to be foldable.

The corrugated pallet 12 is a two-way insertion pallet, as shown in Fig. 2, the corrugated pallet 12 is composed of a tray 13, two fork insertion members 14, three beams 15 and a deck board 16, Two fork insertion members 14 and three beams 15 are disposed between the bottom plate 13a of the deck board 16 and the lower surface of the deck board 16 and fixed by glue bonding by a bonding agent Respectively.

Thus, the fork insertion member 14, the beam 15, and the deck board 16 are accommodated in the tray 13, so that the tray 13 is not exposed to the outside.

However, the process of making a space for accommodating the corrugated pallet 12 in the corrugated cardboard box 1 of Patent Document 2 is very complicated.

That is, the tray 13 is folded and joined, the fork insertion member 14 and the beam 15 are inserted into the tray 13, and the deck board 16 is inserted thereinto. Further, the corrugated board shell 4 is placed on the deck board 16 and the cardboard lid 3 is closed.

In the corrugated cardboard packaging box according to claim 7 of the present invention, it is preferable that the beam is disposed in the non-folding section.

In the corrugated board packaging box according to claim 8 of the present invention, it is preferable that the horizontal cutting line is at the same height as the fold line of the left and right flaps.

A developed view for a corrugated cardboard packaging box according to claim 9 of the present invention includes a front plate and a right plate connected by a vertical folding line, a front flap connected to a horizontal folding line at the bottom of the front plate, a horizontal flap at the bottom of the right plate, A first deployment view including a right flap connected to a line, and a first adhesive band connected by a vertical fold line to the outside of the front flap; A rear flap connected to the horizontal folding line at the lower end of the rear flap; a left flap connected to the horizontal folding line at the lower end of the left flap; And a second development zone including a second adhesive band connected by a folding line, wherein the horizontal folding line of the front and rear flaps is disposed above the horizontal folding line of the left and right flaps.

A method of assembling a corrugated cardboard box according to Claim 10 of the present invention comprises the steps of: preparing a corrugated cardboard box in which the folding lines of the front and rear flaps are disposed above the fold lines of the left and right flaps; Folding the front and rear flaps; Placing a corrugated pallet on the folded front and rear flaps; And folding the left and right flaps.

The present invention has the following effects.

The left and right flaps can be folded and the corrugated pallet part can be simply installed at the lower part thereof.

That is, if the folded lines of the left and right flaps are folded together with the difference in the height of the fold lines of the front and rear flaps, a fork insertion opening is formed between the folded left and right flaps and the front and rear flaps so as to penetrate forward and backward.

Further, since the lower ends of the front and rear flaps are disposed above the lower ends of the left and right flaps by the height difference of the fold lines, when the front and rear flaps are folded, there is no portion that does not overlap each other.

On the other hand, since at least one beam is provided in the fork insertion opening, the beam can prevent the front and rear flaps from being unfolded, the load of the object can be supported by the beam, and the opening in which the fork is inserted between the beam and the beam can be guided have. Further, since the beam is contained in the fork insertion opening, there is no fear of collapse or dislocation by the fork.

Furthermore, by embodying a corrugated pallet to which a beam and a board are joined, it is possible to take the form of a pallet simply by folding the front and rear flaps and then immediately inserting the corrugated cardboard pallets.

On the other hand, by arranging the beam in the non-folding section, the non-folding section prevents the beam from falling off before and after the beam.

In addition, since the horizontal cutting line is at the same height as the folding line of the left and right flaps, the lower end of the non-folding section touches the ground and disperses the force, thereby making it possible to reduce the weight to a thin corrugated pallet. It is very advantageous.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 5 is a perspective view showing a corrugated cardboard packaging box according to a preferred embodiment of the present invention, and FIGS. 6 to 9 are perspective views illustrating a corrugated cardboard packaging box of FIG. 5 by assembling a corrugated cardboard box and a corrugated cardboard pallet, , And Fig. 10 is a first developed view (a) and a second developed view (b) showing the development of the corrugated cardboard box portion.

5, the corrugated cardboard packaging box 100 according to the present embodiment includes a corrugated cardboard box portion 300 having an outer shape and a corrugated cardboard pallet portion 500 formed at a lower portion of the corrugated cardboard box portion 300 . Of course, the corrugated cardboard box part 300 is covered with a conventional corrugated cardboard lid.

The corrugated cardboard box portion 300 is a rectangular box having front and rear side plates 301 and 302 and left and right side plates 303 and 304.

6 and 7, the front and rear flaps 310 and 320 that cover the bottom of the corrugated cardboard box part 300 and the corrugated cardboard box part 300 are formed at the lower end of the corrugated cardboard box part 300, Left and right flaps 330 and 340 are folded in a wing shape.

The front and rear flaps 310 and 320, which block the bottom of the corrugated cardboard box part 300, are folded before and after the lower end of the corrugated cardboard box part 300.

The corrugated cardboard pallet part 500 is positioned below the folded front and rear flaps 310 and 320 and has a fork insertion opening 501 formed therein.

That is, the corrugated cardboard pallet part 500 is formed by folding the front and rear flaps 310, 320 and the left and right flaps 330, 340 to form a fork insertion opening 501 therebetween.

6, the folding lines 311 and 321 of the front and rear flaps 310 and 320 are connected to the fold lines 331 and 341 of the left and right flaps 330 and 340, As shown in FIG.

The difference in height Δ between the folding lines 311 and 321 and the folding lines 331 and 341 is a stepped shape when the front and rear flaps 310 and 320 and the left and right flaps 330 and 340 are folded The fork insertion opening 501, which is a space, is naturally created.

The lower ends 312 and 322 of the front and rear flaps 310 and 320 are disposed above the lower ends 332 and 342 of the left and right flaps 330 and 340 by the height difference Δ, So that the lower ends 312 and 322 of the front and rear flaps 310 and 320 are folded to each other without overlapping each other as shown in FIG.

On the other hand, non-folding sections 313 and 323 are formed on the fold lines 311 and 321 of the front and rear flaps 310 and 320, respectively.

The non-folding sections 313 and 323 are separated from the front and rear flaps 310 and 320 by the vertical cutting lines 315 and 325 and the horizontal cutting lines 316 and 326, respectively.

That is, the non-folding sections 313 and 323 by the vertical cut lines 315 and 325 and the horizontal cut lines 316 and 326 form the wall 317 which is not integrally folded with the front and rear side plates 301 and 302, (327).

It is also preferable that the horizontal cutting lines 316 and 326 are flush with the fold lines 331 and 341 of the left and right flaps.

Accordingly, the lower ends of the walls 317 and 327 are brought into contact with the ground along with the folding lines 331 and 341, thereby dispersing the force of the vertical pressing force from above, thereby reducing the weight of the corrugated cardboard pallet 510 described later.

The cardboard pallet 510 is composed of a plurality of beams 511a to 511c and a board 513 to which the beams 511a to 511c are joined as shown in Fig.

The beams 511a to 511c are made of honeycomb, and the board 513 is made of the thinnest corrugated board.

That is, since the board 513 is only required to close the front and rear flaps 310 and 320, the board 513 needs to be thin, and the support of the board 513 supports the beams 511a to 511c provided under the support, have.

The middle beam 511b of the beams 511a to 511c is wider than the edge to allow the fork insertion opening 501 to be stably supported without collapsing.

Between the beams 511a to 511c serves as a path for inserting the fork.

As shown in FIG. 7, the corrugated cardboard pallet 510 is placed on the underside of the folded front and rear flaps 310 and 320 to prevent the board 513 from blocking the corrugated cardboard pallets 510, do.

Of course, at least one beam may be installed in the fork insertion opening 501 without a board.

In addition, the beam and the board may be separately constructed, and the boards may be placed on the folded front and rear flaps 310 and 320, and the beams may be placed thereon.

However, if the board and the beam are not connected and are separately configured, the storage and assembly are very troublesome.

In addition, if it is installed in the fork insertion opening 501 with only the beam without the board, the bottom surface of the folded front flaps 310 and the folded flaps 310 can be completely blocked,

Therefore, as shown in FIG. 7, a single corrugated pallet 510 having the beams 519a to 511c bonded to the board 513 is optimal for assembly.

It is also preferable that the front and rear of the beams 511a to 511c are disposed between the walls 317 and 327 of the non-contact sections 313 and 323.

That is, when the corrugated cardboard pallet 510 is received in the fork insertion opening 501, it prevents the cardboard pallet 510 from falling in the forward and backward directions.

10 is a developed view for a corrugated cardboard packaging box.

The first developed view of Fig. 10 (a) shows the front and rear plates 301 and 304 connected to each other by the vertical folding line 305 and the front folding line 311 connected to the horizontal folding line 311 at the lower end of the front plate 301 A right flap 310 and a right flap 310. A right flap 340 is connected to the horizontal folding line 341 at the lower end of the right flap 304. A right flap 340 is connected to the outer folding line 310 and the vertical folding line 306, 301a.

10B is connected to the horizontal folding line 321 at the lower ends of the rear side plate 302 and the left side plate 303 and the rear side plate 302 connected by the vertical folding line 307 A flap 320, a left flap 330 connected to the horizontal folding line 331 at the lower end of the left plate 303, a second bonding strip (not shown) connected to the outer side of the rear flap 320 and the vertical folding line 308 302a.

The horizontal folding lines 311 and 321 of the front and rear flaps 310 and 320 are disposed above the horizontal folding lines 331 and 341 of the left and right flaps 330 and 340.

5, the first adhesive band 301a is adhered to the left plate 303 and the second adhesive band 302a is adhered to the right plate 304. As shown in FIG.
