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.

A low height and long width package, such as a box for packaging such as egg seats or air conditioner piping, requires a structure and strength to support a certain load or more.

In particular, various forms of the low-stage packaging box for the egg seat has been presented in the past, one example of which is shown in the development of FIG. The low-stage packaging box shown in FIG. 1 is disclosed in Korean Laid-Open Patent Publication No. 2001-16501.

As shown in FIG. 1, the packing box includes a bottom portion 100 having lower bends 110a and 110b formed at four ends, and two pairs formed by bending at lower end portions 110a and 110b. Side walls 200 and 300, and two cover parts 200 extending from the pair of side walls 200.

At the center of the end of the cover 220, the support wing 230 is extended. In addition, the semicircular insertion blades 250 are formed at left and right ends of the lid part 200 and inserted into the insertion grooves 340 formed at the center of the bent portion 310 of the support blade 320. The outer side of the semi-circular insertion blade 250 is bent at the left and right ends of the cover portion 220, the inside is cut to be inserted into the insertion groove 340. In addition, in order to reinforce the strength of the side wall 300, a pair of side wall support blades 330 extend from both sides of the side wall 300, so that each side wall support blades 330 abut against the inner wall of the side wall 300 adhesive It is attached by an adhesive means such as.

By the way, the low-end packaging box as described above has an effect that the assembly operation is very simple by inserting the insertion blade 250 in the insertion groove 340, the side wall support wing 330 for the strength of the side wall is the side wall 300 ), There is still an inconvenience of assembly that must be adhered with an adhesive.

In addition, since the packaging box is kept assembled by simply inserting, there is also a problem in that the strength is very weak and the packaging box may collapse from only a slight load.

The present invention was devised to solve the assembly discomfort of the conventional low-stage packaging box, and eliminates the insertion assembly method, and also changes the sidewall support method, simplifying the assembly structure for sidewall support and collapse It is an object of the present invention to provide a low-stage packaging box that can be completely eliminated.

In order to achieve the above objects of the present invention, the low-stage packaging box according to the present invention includes a bottom plate. First to fourth side plates having the same height on four sides of the bottom plate are formed through the fold line. A pair of side wall support plates are formed on both sides of opposing first side plates and third side plates via fold lines. The end of one side wall support plate is formed with a locking groove from the top to the bottom, while the end of the other side wall support plate is formed with a locking groove from the bottom to the top. When each side wall support plate is folded and fitted to the inner walls of the first side plate and the third side plate, the end portions of the side wall support plates overlap with each other, and the side wall support plates are held in a fixed state by sandwiching the engaging grooves in this state. . In addition, horizontal support plates perpendicular to the respective side plates are formed on the upper ends of the first side plate and the third side plate through the fold line.

A pair of cover plates are formed on the upper ends of the second side plate and the fourth side plate to extend horizontally through the fold line. Both bottoms of each cover plate are opposed to each horizontal support plate, and the ends are fixed with adhesive tape in abutted or partially overlapped state.

According to the above-described configuration of the present invention, the engagement grooves formed in the sidewall support plate are fitted to each other, so that the sidewall support plate is kept in an upright position on the inner wall of the side plate, so assembly is very easy, and each cover plate supported by the horizontal support plate is bonded. Since it is fixed with tape, the strength is very strengthened and the fear of collapse is eliminated.

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.

Figure 2 is a development view showing a low-stage packaging box according to the present invention, Figure 3 is a perspective view showing the assembly structure of the side wall support plate which is the main part of the present invention, Figure 4 is a final assembly of the packaging box showing a state where the cover plate is completely covered 5 is a perspective view of the final assembly showing another connection structure of the cover plate.

First, referring to FIG. 2, first to fourth side plates 21, 22, 23, and 24 are formed on all four sides of the rectangular bottom plate 10 via a fold line. In FIG. 2, the left side plate is the first side plate 21, and the second to fourth side plates 22, 23, 24 are disposed along the clockwise direction. Accordingly, the first side plate 21 and the third side plate 23 face each other, and the second side plate 22 and the fourth side plate 24 face each other. Of course, each side plate (21, 22, 23, 24) is to be installed on the side of the bottom plate 10, the height is of course the same.

Four pairs of side wall support plates 31, 32, 33, and 34 are formed through fold lines from both side surfaces of the first side plate 21 and the third side plate 23, respectively. Each side wall support plate 31, 32, 33, 34 is folded through a fold line so as to abut against inner walls of the first and third side plates 23. In particular, each of the side wall support plates 31, 32, 33, 34 has a length such that the end portions of the side wall support plates 31, 32, 33, 34 overlap each other.

In this way, the overlapping grooves 35 and 36 are formed in opposite directions to each other. That is, in the first side plate 21, the engaging groove 35 is formed from the top to the end of the side wall support plate 31 facing downward. On the other hand, at the end of the side wall support plate 32 facing upwards, a locking groove 36 is formed from below. Here, the formation direction of the locking grooves 35 and 36 is explained in the up and down direction because the side wall support plates 31, 32, 33, and 34 are vertically assembled, and this is assumed. As the engaging grooves 35 and 36 are fitted to each other, the side wall support plates 31 and 32 are brought into abutment against the inner wall of the first side plate 21 while being firmly connected.

In particular, in order to facilitate the fitting between the engaging grooves 35 and 36, the partial heights of the engaging grooves 35 and 36 and the ends of the side wall support plates 31 and 32 are preferably slightly shorter than the heights of the side wall support plates 31 and 32. Do. That is, the upper end of the side wall support plate 31 in which the locking groove 35 is formed from above has a stepped shape from the locking groove 35 forming portion downward. On the other hand, the lower end of the side wall support plate 32 on which the catching grooves 36 are formed from below has a stepped shape upward from the forming portion of the catching grooves 36. Since the side wall support plates 33 and 34 of the third side plate 23 are also the same as those of the first side plate 21, they will not be repeated.

On the other hand, horizontal support plates 41 and 42 are horizontally formed on the upper ends of the first side plate 21 and the third side plate 23 through the fold line. Each of the horizontal support plates 41 and 42 has a relatively short length and has a function of supporting the cover plates 51 and 52 to be described later.

Subsequently, a pair of cover plates 51 and 52 extend horizontally from the upper end of the 2nd side plate 22 and the 4th side plate 24 via a fold line. Accordingly, both bottom surfaces of the cover plates 51 and 52 are placed on and supported by the horizontal support plates 41 and 42 as described above.

Each cover plate 51, 52 has a length such that at least each end portion is abutted with each other, that is, half length of the first side plate 21, as shown in FIG. In addition, in order to enhance the strength of the cover plates 51 and 52, as shown in FIG. 5, one cover plate 52a may be slightly longer than the other cover plate 51, and a part may overlap. In either case, the ends of each cover plate 51 and 52a are bonded and connected with a general adhesive tape 60 used for fixing the interface of the packaging box.

Hereinafter, the operation of assembling the low-end packaging box according to the present embodiment configured as described above will be described in detail with reference to the accompanying drawings.

First, in the state of FIG. 2, the fold lines between the bottom plate 10 and the side plates 21, 22, 23, and 24 are folded to set up the side plates 21, 22, 23, and 24. Then, the side wall support plates 31, 32, 33, 34 are folded to abut against the inner walls of the first and third side plates 21, 23, and then the locking grooves 35, 36 are sandwiched with each other. It becomes the state shown. Then, the horizontal support plates 41 and 42 are folded horizontally.

Finally, as shown in Fig. 4, the cover plates 51 and 52 are folded horizontally and placed close to each other. Then, both bottom surfaces of the cover plates 51 and 52 are supported from the bottom by the horizontal support plates 41 and 42. In this state, the adhesive tape 60 is adhered along the boundary surface of each cover plate 51 and 52 to connect each cover plate 51 and 52 with each other.

In another variation, if the length of one cover plate 52a is longer than the length of the other cover plate 51 as described above, the adhesive tape 60 is placed along the overlapped portion as shown in FIG. 5. Attached.

On the other hand, the low-stage packaging box according to the present embodiment may be used for egg seats or air conditioning piping, depending on the thickness of the cardboard, of course, can be used for other packaging of low height.

As described above, according to the present invention, since the side wall support plates are connected by fitting instead of the adhesive method, there is an advantage that the assembly of the side wall support plates becomes very easy.

In addition, since the cover plate is fixed with an adhesive tape, the strength of the packaging box itself is greatly strengthened, and the packaging box can be prevented from collapsing even with a slight load.

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.
