Abstract

A low stage packaging box is disclosed. The disclosed low stage packaging box includes a bottom plate and four first to fourth side plates and a top plate having the same bottom plate size. The first and second side plates are formed via fold lines on two opposite sides of the bottom plate. The upper plate is formed on the upper end of the second side plate via a fold line. The third and fourth side plates are formed on each side of the second side plate via a fold line. The height of the third and fourth side plates is the same as the height of the first and second side plates, and the length is the same as the other two side lengths of the bottom plate. At the lower ends of the third and fourth side plates, horizontal support plates placed on the bottom plate are formed via the fold line. Vertical support plates are formed on both sides of the first side plate via fold lines, so that each vertical support plate is abutted on the inner surfaces of the third and fourth side plates. Therefore, since all four side plates have a vertical valley direction, the force to withstand the load from above is greatly strengthened. Therefore, the packaging box collapses due to a slight load, thereby preventing the contents from being broken.

Description

LOW HEIGHT TYPE PACKING CASE}

The present invention relates to a low-stage packaging box, and more particularly to a low-stage cardboard box of low height.

For example, since the pizza is low in height and large in area, the pizza box is low in height and long in length and length, that is, in a low stage shape. As such a packing box for pizza, paper, especially cardboard having a constant bone direction, is mainly used.

An example of the prior art of the various types of such low stage packaging boxes is shown in development in FIG. 1.

1, the bottom plate 1 is a rectangle whose horizontal length is longer than the vertical length. The first and second side plates 2, 3 are formed on two long sides of the bottom plate 1 via fold lines. In addition, the third and fourth side plates 4 and 5 are formed on two short sides of the bottom plate 1 via a fold line. The height of each side plate 2, 3, 4, 5 is the same, and is low. On the long side of the second side plate 3, an upper plate 6 having the same size as the bottom plate 1 is formed via the fold line.

Vertical support plates 8 and 9 are formed on the respective short side surfaces of the first and second side plates 2 and 3 via fold lines so that the vertical support plates 8 and 9 are formed by the third and fourth side plates 4, By being abutted against the inner side of 5), each side plate 2, 3, 4, 5 is kept in an upright position.

On the long side surface of the upper plate 6, a coupling plate 7 which abuts against the outer surface of the first side plate 2 is formed via a fold line. Insert plates 10 are formed at two end sides of the coupling plate 7.

The cardboard box made of such a structure is formed by cutting a wide corrugated cardboard as described above. Thus, the bone direction is directed only in one direction as shown by the dotted line in FIG.

Therefore, when the packaging box shown in FIG. 1 is folded as shown in FIG. 2 by folding each fold line, the valley direction of the first and second side plates 2 and 3 becomes a vertical direction. However, the valley direction of the third and fourth side plates 4 and 5 is the horizontal direction.

For this reason, the conventional low-stage packaging box has a disadvantage that the third and fourth side plates 4 and 5 are weaker in supporting strength than the first and second side plates 2 and 3 against the load from above. In other words, even if a slight load is applied to the packaging box from above, the third and fourth side plates 4 and 5, which are weak in supporting strength, collapse, and the contents of the packaging box are damaged.

Therefore, the present invention was devised to solve the shortcomings of the conventional low-stage packing box, so that the bone direction of each side plate is in the vertical direction, and the low-stage packing with enhanced bearing strength against the load from above. The purpose is to provide a box.

In order to achieve the objects of the present invention described above, the low-stage packaging box according to the present invention includes a bottom plate, four first to fourth side plates, and a top plate having the same bottom plate size. The first and second side plates are formed via fold lines on two opposite sides of the bottom plate. The upper plate is formed on the upper end of the second side plate via a fold line.

The third and fourth side plates are formed on each side of the second side plate via a fold line. The height of the third and fourth side plates is the same as the height of the first and second side plates, and the length is the same as the other two side lengths of the bottom plate. At the lower ends of the third and fourth side plates, horizontal support plates placed on the bottom plate are formed via the fold line.

Vertical support plates are formed on both sides of the first side plate via fold lines, so that each vertical support plate is abutted on the inner surfaces of the third and fourth side plates. In order to reinforce the vertical support strength of the third and fourth side plates, it is preferable that a vertical reinforcement plate overlapping the inner surface of each vertical support plate is formed on the upper end of the third and fourth side plates via a fold line.

On the long side of the top plate, a joining plate that is opposed to the outer side of the first side plate is formed via the fold line. Inserting plates are formed on each short side of the joining plate via a fold line. Each insert plate is inserted between the third and fourth side plates and the vertical support plate.

According to the configuration of the present invention described above, since the third and fourth side plates are formed on each of the short side surfaces of the second side plates, the third and fourth side plates are rotated 90 ° horizontally after the third and fourth side plates are erected, so that only the first and second side plates Not only the bone direction of the third and fourth side plates is also directed in the vertical direction.

Hereinafter, the low-stage packaging box according to a preferred embodiment of the present invention will be described in detail with reference to the drawings, but the present invention is not limited or limited by the following embodiments.

<Example 1>

Figure 3 is a development view showing a low-stage packaging box according to a first embodiment of the present invention, Figure 4 is a perspective view of a packaging box showing a state before the top plate is covered, Figure 5 is a packaging box showing a state that the top plate is completely covered Is the final assembled perspective view.

As shown in FIG. 3, the bottom plate-shaped packing box according to Embodiment 1 of the present invention includes a bottom plate 20, four first to fourth side plates 31, 32, 33, 34, and a top plate 50. Include. Since the bottom plate 20 and the top plate 50 are the same size and have a bottom plate shape, the height of each side plate 31, 32, 33, 34 is low.

The bottom plate 20 is a rectangle whose horizontal length is longer than the vertical length, and the first side plate 31 is formed on any one side surface of the bottom plate 20. A fold line is formed between the long side surface of the first side plate 31 and the bottom plate 20. The second side plate 32 facing the first side plate 31 is formed on the other long side surface of the bottom plate 20, and a fold line is formed therebetween.

The third and fourth side plates 33 and 34 are formed on both side short sides of the second side plate 32 via fold lines. That is, in the present invention, the third and fourth side plates 33 and 34 are not formed on the short side surface of the bottom plate 20 as in the prior art, but are formed on the short side surface of the second side plate 32, so that The valley direction of the third and fourth side plates 33 and 34 can be directed in the vertical direction like the first and second side plates 31 and 32. Of course, the lengths of the third and fourth side plates 33 and 34 correspond to the short side lengths of the bottom plate 20, that is, almost the same.

Horizontal support plates 35 and 36 are formed at lower ends of the third and fourth side plates 33 and 34. The horizontal support plates 35 and 36 are horizontally placed on the bottom plate 20 to support the third and fourth side plates 33 and 34 and to reinforce the strength of the bottom plate 20. In particular, each horizontal support plate (35, 36) is a longitudinal length, when placed on the bottom plate 20, the horizontal length is half of the long side length of the bottom plate 20, that is, the area of the horizontal support plate (35, 36) is the bottom plate 20 ) It is desirable to be half of the area. The reason is that when the horizontal support plates 35 and 36 are placed on the bottom plate 20, it is more advantageous for the strength reinforcement of the bottom plate 20 that the adjacent side surfaces of the horizontal support plates 35 and 36 face each other. This is because it looks good.

Two vertical support plates 37 and 38 are formed on both sides of the first side plate 31 via fold lines. Each vertical support plate 37, 38 is placed on the horizontal support plates 35, 36 to abut against the inner surfaces of the third and fourth side plates 33, 34. The vertical support plates 37 and 38 are preferably bonded to the inner surfaces of the third and fourth side plates 33 and 34 by an adhesive or fixed by staplers. Further, in order to reinforce the overall strength of the third and fourth side plates 33 and 34, the length of each vertical support plate 37 and 38 is more preferably the same as the length of the third and fourth side plates 33 and 34. .

In addition, it is preferable that the vertical reinforcement plates 39 and 40 are formed on the upper ends of the third and fourth side plates 33 and 34 through the folding line. Each vertical reinforcement plate 39, 40 is abutted against the inner surfaces of the vertical support plates 37, 38, and is fixed to the third and fourth side plates 33, 34 together with the vertical support plates 37, 38. Therefore, it is preferable that the height of each vertical reinforcement plate 39 and 40 is the same as the height of the third and fourth side plates 33 and 34. On the other hand, a pair of vertical retaining plates 41 are formed at the upper ends of the vertical reinforcing plates 39 and 40, and the vertical retaining grooves 42 into which the vertical retaining plates 41 are inserted are the third and fourth side plates. It is more preferable to be formed laterally in the part between (33,34) and the horizontal holding plates 35,36.

A coupling plate 51 is formed on the long side surface of the upper plate 50, and the coupling plate 51 abuts against the outer side surface of the first side plate 31. The height of the coupling plate 51 is preferably the same as the height of the first side plate 31. A pair of insertion plates 52 and 53 having an approximately 1/4 arc shape are formed on both sides of the coupling plate 51 via a fold line. Each insertion plate 52, 53 is inserted between the third and fourth side plates 33, 34 and the vertical reinforcement plates 35, 36.

The process of assembling the packaging box by folding the developed view of FIG. 3 having the above configuration along the fold line will be described in detail.

The horizontal support plates 35 and 36 and the vertical reinforcement plates 39 and 40 are folded at 90 degrees. Next, the third and fourth side plates 33 and 34 are folded inward by 90 degrees. Then, when the second side plate 32 is folded up by 90 °, the third and fourth side plates 33 and 34 are short sides of the bottom plate 20 while the horizontal support plates 35 and 36 are placed on the bottom plate 20. Placed in a standing position. At this time, the third and fourth side plates 33 and 34 are oriented in the vertical direction, as shown by the dotted lines in FIG. 4, like the first and second side plates 31 and 32. In addition, since adjacent side surfaces of the respective horizontal support plates 35 and 36 face each other, the bottom surface of the packaging box becomes a double structure in which the bottom plate 20 and the two horizontal support plates 35 and 36 overlap each other, thereby becoming more robust.

Subsequently, the vertical support plates 37 and 38 are folded at 90 °, and then the vertical support plates 37 and 38 are folded to the 90 ° by folding the first side plates 31 at 90 °. Butt against the inner side. In this state, each of the vertical reinforcing plates 39 and 40 abuts against the inner surface of each of the vertical supporting plates 37 and 38. Then, when the vertical retaining plate 41 is inserted into each vertical retaining groove 42, the single-sided structure of the packaging box becomes a structure in which three layers of corrugated cardboard are overlapped, thereby further strengthening the strength.

Finally, after folding the upper plate 50 by 90 ° to level it, each insertion plate 52, 53 is removed while the coupling plate 51 is folded by 90 ° to face the outer surface of the first side plate 31. It is inserted between the third and fourth side plates 33 and 34 and the vertical support plates 35 and 36. Then, as shown in FIG. 5, the assembling of the packing box is completed in a state in which the top plate 50 is firmly coupled to the first side plate 31.

In the packaging box assembled in this state, since all four side plates 31, 32, 33, and 34 have a vertical valley direction, the force supporting the load from above is greatly enhanced. Therefore, the box is collapsed by the load from above, and the situation where the contents inside it are damaged is prevented.

Moreover, the bottom of the packaging box also has a double structure, and the strength of supporting the contents from below is also enhanced. In addition, since the third and fourth side structures are tripled, the bone direction is further strengthened in addition to the vertical one.

Figure 6 is a development view showing a low-end packaging box according to a second embodiment of the present invention, Figure 7 is a perspective view of the packaging box showing a state before the top plate is covered.

The developed view of the packaging box according to the second embodiment shown in FIG. 6 is mostly the same as the developed view of the packaging box according to the first embodiment, except that the shape of the vertical support plate is slightly different. Therefore, the rest of the components except the vertical support plate are not repeatedly described and the same reference numerals are given.

Referring to FIG. 6, two fold lines 63 and 64 are formed laterally on both vertical support plates 61 and 62. Accordingly, the vertical support plates 61 and 62 can be folded in the form of a 'C' along the fold lines 63 and 64.

On the other hand, at the lower end of each of the vertical support plates (61, 62) are formed arched fixing plates (65, 66). Fixing grooves 67 and 68 into which the fixing plates 65 and 66 are inserted are laterally formed in the vertical reinforcing plates 39 and 40. In addition, it is preferable that fixing grooves 69 and 70 into which the fixing plates 65 and 66 are inserted are also formed in each of the vertical support plates 37 and 38.

It is comprised as mentioned above, and abuts the vertical support plates 37 and 38 with each horizontal support plate 61 and 62 settled on the bottom plate 20. As shown in FIG. Subsequently, the vertical reinforcing plates 39 and 40 are brought into contact with the inner surfaces of the vertical supporting plates 37 and 38, and then the vertical holding plates 41 are inserted into the vertical holding grooves 42 to thereby form the third and fourth side plates 33. 34) to be kept vertical.

Subsequently, when the horizontal support plates 61 and 62 are folded along the fold lines 63 and 64, the horizontal support plates 61 and 62 are in the form of a 'C'. Then, as shown in FIG. 7, the fixing plates 65 and 66 are inserted into the respective fixing grooves 69 and 70 to maintain the horizontal supporting plates 61 and 62 in the U shape. In this case, since the stepped structures formed by the horizontal support plates 61 and 62 are formed on both sides of the bottom plate 20, the stepped structures serve as a buffering function or a pedestal of the contents.

Finally, as in Embodiment 1, the respective insertion plates 52 and 53 are sandwiched between the third and fourth side plates 33 and 34 and the vertical support plates 37 and 38, whereby the packing box according to Embodiment 2 is finally Is assembled.

As described above, according to the present invention, since all four side plates have a vertical bone direction, the force to withstand the load from above is greatly enhanced. Therefore, the packaging box collapses due to a slight load, thereby preventing the contents from being broken.

In the above description and illustration of a low-stage packaging box according to a preferred embodiment of the present invention, but the present invention is not limited to the above-described embodiment without departing from the gist of the present invention claimed in the utility model registration claims below It will be understood by those skilled in the art that the present invention may be modified in various ways.
