Description

A packing box of stack type}

The present invention relates to a multilayer packaging box, and relates to a multilayer packaging box that surrounds the outer circumference of an article that needs packaging or can be stored in a box shape, or can be folded and stored when there is no product that needs packaging.

In general, a Danpla box (hereinafter simply referred to as a box) is widely used for transporting parts or products.

These boxes are generally made of synthetic resin materials. Synthetic resin materials used in the molding of such boxes are, for example, polyethylene (PE) or polypropylene (PP), or polymers thereof are used as main components.

In addition, a box manufactured using such a synthetic resin material is cut into a predetermined shape capable of completing the box using raw materials in a plate state, and stapling is performed on overlapping portions while folding the raw materials cut in this way. do. Therefore, metal staples are always present in the finished packaging box.

In a box completed by the stapling process, the above-described metal staples are generally present on the bottom surface as well as the side surface of the packing box.

However, a box manufactured using Danpla must be subjected to a stapling process. However, when the Danpla thickness is increased to withstand a vertical load, box manufacturing through the stapling process becomes difficult. In addition, since the Danpla box is vulnerable to vertical load, there is a limit in stacking the boxes in the height direction, so there is a problem of poor industrial applicability.

6 to 8, the multilayer packaging box 200 according to the second embodiment of the present invention includes a side plate portion 210, a reinforcing portion 220, and a steel guide 230.

Since the side plate portion 210 has a basically the same structure as that of the first embodiment described above, redundant description will be omitted.

However, the side plate portion 210 is folded so as to be folded or unfolded with a groove 211 formed in the central region excluding the region to which the reinforcing portion 220 to be described later is coupled. That is, in the side plate portion 210, “W” shaped grooves 211 are formed outside the center of the two surfaces facing each other, and each surface facing each other is folded so as to overlap in the direction of the inner accommodation space 212. can be folded.

The side plate portion 210 includes a first side plate 211 and a second side plate 212 disposed in at least a vertical direction, and a reinforcement part 220 is provided between the first side plate 211 and the second side plate 212. is combined The first side plate 211 and the second side plate 212 may be arranged such that two side plates having the same shape are manufactured and stacked with each other in a vertical direction. In this embodiment, the side plate 110 includes the first side plate 211 to the third side plate 213, and three side plates in which the third side plate 113 is disposed on the first side plate 111 are stacked. An example will be described.

The steel guide 230 has a substantially "c" shaped frame structure and is coupled to surround the lower end of the second side plate 212 . In addition, the steel guide 230 is provided with at least two or more protrusions 231 on the surface facing the pallet P to prevent slipping on the pallet P.

The reinforcing part 220 includes a first H beam 221 made of a metal material, a second H beam 222, a U-shaped pin 223 and a perforated clip 224. Of course, the reinforcing part 220 may also be made of other materials that provide rigidity within the set allowable range.

The first H beam 221 is disposed on top of each side plate, and the second H beam 222 is disposed on the bottom of each side plate. At this time, the first H beam 221 and the second H beam 222 are positioned on the same side surface, but are disposed at a position out of the center area that is folded from the center of the side surface.

The first H beam 221 and the second H beam 222 have an "H" shape in one cross section, and may be stacked so as to prevent them from being spaced apart in the horizontal direction while partially inserting side plate portions into the upper and lower portions, respectively. At this time, , Fastening grooves (not shown) may be formed at the upper and lower ends of the side plate portion to which the first H beam 221 and the second H beam 222 are coupled. Therefore, the first H beam 221 and the second H beam 222 Since silver is partially inserted into the fastening groove on the side plate, it can be fixed so that slip does not occur along the longitudinal direction of the side plate.

The U-shaped pin 223 penetrates the through hole 10 formed between the inner partition walls of the side plate portion 210 while being inserted through the pair of first coupling holes 225 formed on the upper portion of the first H beam 221, , Passing through the second coupling hole 226 of the 2H beam 222 disposed below the side plate portion 210, and coupled to the perforated clip 224 provided below the 2H beam 222.

Since both ends of the U-shaped pin 223 are elastically disposed outward, a force to spread outward on the third coupling hole 228 acts, so that both ends of the U-shaped pin 223 are not forcibly closed. It is coupled so that it cannot be removed unless otherwise specified. For example, the perforated clip 224 is preferably made of metal or synthetic resin material. Of course, the perforated clip 224 may be applied to a structure that elastically supports both ends of the U-shaped pin 223 while being made of a material having an elastic restoring force.

The reinforcing part 220 is different from the first reinforcing part 220a coupled to a position spaced apart from the center of either side of the first side plate 211 to one side, and the center of either side of the third side plate 213. It includes a second reinforcing part (220b) coupled to a position spaced apart from the side. Of course, although not shown in the drawing, when a fourth side plate (not shown) or more side plate parts are added, a third reinforcement part (not shown) or more reinforcement parts may be added.

At this time, the first reinforcing part 220a and the second reinforcing part 220b are arranged in a zigzag direction with respect to one side of each side plate. That is, on the first side plate 211, the first reinforcement part 220a is coupled to one side (right side) off center, and on the third side plate 213, on the other side (left side) off center, the second reinforcement part ( 220b) is combined.

The side plate portion 210 may be coupled with one reinforcing portion 220 on one side or the other side out of the center on each side.

Therefore, according to the multilayer packaging box according to the present invention, the side plates can be folded and unfolded, so the volume of the foldable packaging box can be significantly reduced in the transportation process, and since the reinforcing parts made of metal connect each side plate in the vertical direction, the height can be adjusted. It is easy, it can be easily fixed on a pallet through a steel guide, and since the reinforcing part is coupled to be inserted at least partially into the inner hole of the side plate part, a strong coupling is possible, and there is an effect that can sufficiently withstand the load of the stored goods.

Although the above has been shown and described as specific embodiments to illustrate the technical idea of the present invention, the present invention is not limited to the same configuration and operation as the specific embodiments as described above, and various modifications do not depart from the scope of the present invention. can be carried out within Accordingly, such modifications are to be regarded as falling within the scope of the present invention, which scope is to be determined by the claims set forth below.
