The present invention relates to a box for packing various articles, and more particularly, to a box for packing a good lower binding force in which the lower coupling structure is more securely configured, so that the contents do not fall down and stably function properly. will be.

In general, in the case of a packing box containing various items, the four flanges having a flange at the end of the upper and lower openings of the box are generally enclosed in such a manner that one of the two sides is overlapped with the tail bited inward and the other outward. It is common to combine the upper or lower structure of the.

However, in the prior art, there is no problem in the case where the lower area of the box is small or in the case of a square, but there is an obstacle in the configuration in which one side combines a relatively long side packing box. In other words, the longer the length of the combined parts overlapped, the weaker the binding force due to deflection and bending, and the more the weight of the stored object contained therein is easily released. This is especially true in the case of a rectangular rectangular box having a long side on either side.

Therefore, the conventional simple flange-type box is a box packaging by folding the outer flange in the state in which the flange is folded inward and taping along the boundary line where the flange meets.

However, packaging with adhesive or taping is not only cumbersome, but it is not inconvenient for the consumer to tear off or peel off the adhesive layer when opening something.

Therefore, it is desirable to have a strong bonding structure by simple assembly without the need for a separate adhesive or taping, but it is possible to put the light contents, but there is a problem that relatively heavy weight has not been attempted.

Therefore, the present invention was devised in view of the above problems, and an object of the present invention is to provide a relatively low weight of the contents by allowing the packaging box constituting a simple assembly without the need for a separate adhesive or a tape to have a more stable lower coupling structure. It's in the way it can be put.

The object is a rectangular frame body main body is opened up and down;

A lid capable of covering the upper opening of the body; And

Achieved by the first embodiment having folded flanges on both sides of the lower opening of the main body, at least one male engaging portion on one of the flanges on the other side and at least one female engaging portion on the flange on the other side do.

This is achieved by the second embodiment in which a female engaging portion having the same configuration as that of the female engaging portion is formed at a corresponding position of the female engaging portion 35 of the flange 31 which is in contact with the flange 33.

Each of the flanges of the main body is provided with a pair of male and female coupling portions, and the male and female coupling portions of the corresponding flanges are achieved by the third embodiment installed opposite to each other.

Meanwhile, as a fourth embodiment, a rectangular frame body having an upper and lower openings;

A lid capable of covering the upper opening of the body; And

At least one male coupling portion 34 has folding flanges 31, 32, 33, 34 overlapping with each other in front, rear, left, and right sides of the lower opening of the main body, and one side of the folding flange 31, 32. Is achieved by having at least one arm engaging portion 35 coupled to the flanges 30, 33 on the other side.

In the above embodiments, the male coupling part includes a protrusion formed in an opposite direction of the flange connected to the main body, a protrusion protruding out of the flange, and an incision protrusion formed to be cut out from the protrusion in the direction of the main body,

In the above, the female engaging portion is achieved by including a cutout formed in the flange surface corresponding to the protrusion and the cutout protrusion.

In addition, the protrusion and the incision protrusion of the male coupler are formed in a semicircle, and both ends of the incision start portion of the incision protrusion include an extension cut in an opposite curve.

The cutout portion of the female coupling portion is formed in a straight line, each of which comprises an extension portion cut inwardly perpendicularly to each other at both ends of the incision start portion, and between the cutout achieved by further comprising an incision connecting them do.

A lid 20 capable of covering the upper opening of the body; And

It has a folding flange 31 on both sides of the lower opening of the main body, at least one male coupling portion 34 on one flange 32 of the other side and at least one female coupling on the flange 33 of the other side It is characterized by having a combination of the part 35. Of course, the lid 20 in the above is not necessarily limited to the drawings of the embodiment.

For example, it may be a conventional lid structure having four flanges, or may be composed of any known equivalents.

3 is a second embodiment of the present invention, having the same configuration as that of the first embodiment, and the arm at a corresponding position of the arm engaging portion 35 of the flange 31 which is in contact with the flange 33. The female coupling part 35 of the same structure as the coupling part is formed, It is characterized by the above-mentioned.

Meanwhile, as shown in FIG. 4 as a third embodiment of the present invention, each of the flanges 32 and 33 of the main body has a pair of male and female coupling parts 35 and 34, but the male and female coupling parts of the corresponding flanges face each other. Characterized in that installed.

And a rectangular frame body 10 having a top and bottom opening as shown in FIGS. 5A and 5B as a fourth embodiment;

A lid 20 capable of covering the upper opening of the body; And

At least one male coupling portion 34 has folding flanges 30, 31, 32, and 33 overlapping with each other in front, rear, left, and right sides of the lower opening of the main body, and flanges 31, 32 on one side of both sides of the folding flange. And the flanges 30 and 33 on the other side are provided with at least one arm coupling part 35.

In the above embodiments, the male coupling portion 34 is formed in a direction opposite to the flange connected to the main body 10 and protrudes outwardly from the flange 34A and toward the main body from the protruding portion 34A. A cutout protrusion 34B formed by being cut out to protrude,

The female coupling portion 35 is characterized in that it comprises a cutout portion (35A, 35B) formed on the flange surface corresponding to the projection (34A) and the cutout projection (34B).

The protrusion 34A and the incision protrusion 34B of the male coupling part 34 are formed in a semicircle, and both ends of the incision start portion of the incision protrusion 34B are extended to the inverted portion 34b. ),

The cutouts 35A and 35B of the female coupling part 35 are formed in a straight line, and include extension parts 35a and 35b cut inwardly at right angles to each other at both ends of the incision start part, respectively. It is characterized by further comprising a cutout 35C connecting them between the cutouts 35A and 35B.

However, the male coupler and the female coupler are not necessarily limited in shape and will allow replacement by equivalent means.

Referring to the operation of the present invention configured as described above are as follows.

First, the procedure for combining the bottom of the box of the present invention will be described as the first embodiment. As shown in FIG. 2A, the flange 33 is folded to cover the bottom of the main body, and then the projection 34A or the incision projection 34B is unsupported in the male coupling portion 34 on one side regardless of the order. 35A, 35B) to assemble to each (see Fig. 2b).

Then, the other side is assembled by inserting in the same manner as in FIGS. 2C and 2D.

Therefore, the coupling structure of the present invention exerts an action that the lower part of the box can never be opened naturally because the assembly is inserted in different directions.

In addition, at this time, the extension portion 34b cut in opposite curves at both ends of the incision start portion of the incision protrusion 34B from the protrusion 34A and the incision protrusion 34B prevents tearing when the material of the flange is soft. Acts to exert elasticity when bent and released to fit,

Connection between the incisions 35a and 35b and the incisions 35A and 35B which are inverted perpendicularly inwards to each other at each of both ends of the start of each of the cutouts 35A and 35B of the female coupling part 35 The cutout 35C serves to allow the opening of the cutouts 35A and 35B for fitting the protrusions when the material of the box is a hard synthetic resin plate, and the cutout 35C also performs the same function.

On the other hand, the second embodiment as shown in Figure 3 is the same as the operation of the first embodiment, but directionally folded with the male coupling portion 34, the overlapping flanges (31, 33) are closely coupled without lifting each other to the packing box After the coupling configuration of the flange 31 has an action to eliminate the problem such as lifting to the top of the box body (10).

And the third embodiment will provide a higher degree of ease of coupling than unidirectional coupling, as in Fig. 4 by combining the technology or the overall coupling in the cross-coupling manner with the embodiment of the present invention.

On the other hand, the fourth embodiment of the present invention is actually the most preferred embodiment of the present invention, which is suitable for the purpose of the present invention.

That is, the subject of this embodiment is to provide a strong bottom coupling force in the box by applying a structure that combines all the flanges (30, 31, 32, 33) of the bottom of the box body (10). In other words, as in 5a, a box with a narrow width on one side and a long length on the other side will not only have a good bond strength by achieving a coupling structure of at least three points but also the direction of the bond will also be changed from side to side. Provides a wide range of acceptable effects from side to side.

Alternatively, as shown in FIG. 5B, even in the case of a box having a generally square plane or a relatively large box, a relatively heavy article may be embedded as in FIG. 5A, which is also coupled by the fourth embodiment of the present invention. Taking the point more than 4 points, as described above, the direction of the combination also provides an effect that can be widely accommodated from side to side and left and right.

The present invention constructed and acted as described above has an effect of improving the bonding structure and strength in bonding the box assembly structure of the simple assembled type not by the adhesive.
