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.

1 and 2, the wire-reinforced laminated packaging box 100 according to the embodiment of the present invention includes a side plate portion 110 and a reinforcement portion 120.

First, the side plate portion 110 has a corrugated cardboard shape and is made of polypropylene copolymer (PP Coplymer) resin. More specifically, the side plate portion 110 is made of a plastic corrugated cardboard structure called danpla.

This side plate portion 110 is light, tough, can provide chemical resistance and chemical resistance, and can provide heat insulation and sound insulation effects. Accordingly, the side plate portion 110 may be applied to packaging materials, building materials, cushioning materials, and the like. Of course, the side plate portion 110 may be manufactured using other materials according to the type or use of the packaged object.

The side plate portion 110 has a thin plate shape, and a plurality of through holes (see FIG. 4, 10) penetrating the inside along the extrusion direction are formed. For example, the side plate portion 110 includes a pair of plate materials (see FIG. 4 11) facing each other and a partition wall (see FIG. 4 12) that connects the pair of plate materials 11 to each other but is spaced apart from each other at equal intervals. It can be made up of the structure of.

The side plate unit 110 includes at least a first side plate 111 and a second side plate 112 disposed in the vertical direction. The reinforcing part includes a first reinforcing part 120a coupled to the first side plate 111 and a second reinforcing part 120b coupled to the second side plate 112 . The first side plate 111 and the second side plate 112 may have the same shape as each other, and may be stacked vertically with each other. In this embodiment, three side plates including the first side plate 111 to the third side plate 113 of the side plate unit 110 will be described as an example.

The first side plate 111 to the third side plate 113 may be bent into a rectangular structure as shown in FIG. 1 . Alternatively, the side plate portion 110 may be bent into a quadrangular structure, and both ends thereof may be joined. Of course, the shape of the side plate portion 110 may be made of a polygonal shape of more than a triangle according to the number of bending areas, or may be made of an asymmetrical shape.

The side plate portion 110 may be folded while the central regions CA of both sides facing each other are folded inward or unfolded outward. At this time, the reinforcing part 120 may be disposed in an area outside the center area CA of both sides facing each other. Of course, the reinforcing part 120 may be disposed in the central region on both sides of the side plate 110 that are not folded.

Therefore, when the side plate portion 110 is unfolded, the accommodation space 114 is formed therein, and when the central regions CA of both sides facing each other of the side plate portion 110 are folded inward, the accommodation space disappears and the volume increases. can reduce

The foldable packaging box 100 may be installed on a pallet P so as to be transported and loaded using a forklift or the like.

In addition, while the lower end of the reinforcing part 120 on the pallet P is coupled so as to partially interfere, it may be arranged so that slip does not occur between the pallet P and the wire-reinforced stacked packaging box 100. For example, the insertion member 129 of the reinforcing part 120 to be described later may be exposed to the outside of the pallet P to support the outside of the top edge of the pallet P.

Figure 3 is an exploded perspective view showing one side plate and a reinforcing part corresponding thereto separately in the wire-reinforced laminated packaging box shown in Fig. 2, Figure 4 is a laminated side plate of the wire-reinforced laminated packaging box shown in Figure 2 It is a reference view showing a coupled state for, Figure 5 is a perspective view showing the separated reinforcement portion of the wire-reinforced laminated packaging box shown in Figure 2.

3 to 5, the wire-reinforced laminated packaging box (see FIG. 2, 100) according to an embodiment of the present invention includes a first side plate 111 having a rectangular cross section with an accommodation space 114 formed therein, and , One unit box 100a is constituted by including four reinforcing parts 120 coupled to off-center positions on both sides of the first side plate 111 facing each other.

Therefore, the wire-reinforced stacked packaging box 100 according to the embodiment of the present invention will be described as an example in which three unit boxes 100a are combined (see FIG. 1), and stacked according to the amount or volume of the stored items. The number of unit boxes 100a (or the number of stacks) may be changed.

The reinforcing part 120 includes a ring part 121, a fixing part 124, and a coupling part 127.

The ring part 121 is bent from one end of the fixing part 124 to a substantially "c" shaped frame structure. The first side plate 111 is coupled to the inside of the ring part 121 so as to surround a part of the upper end of the first side plate 111 .

The ring part 121 is a bending member 122 bent in the thickness direction of the first side plate 111 at one end of the fixing part 124, and bent again at the end of the bending member 122 to form a fixing part 124 It includes a holding member 123 disposed to face.

That is, while the bending member 122 and the engaging member 123 are bent in an approximate "L" shape, they are coupled to cover the upper surface and a portion of one side of the first side plate 111 . Although not shown in the drawing, the holding member may be inclined to be bent from an end of the bending member to gradually approach the fixing part. This can increase the bonding strength of the reinforcing part at the top of the first side plate.

Also, the fixing part 124 includes a fixing area 125 and a reinforcing area 126 .

The fixing area 125 is disposed on both sides of the reinforcement part 120 along the longitudinal direction. The fixing area 125 is placed in close contact with the first side plate 111 while being fixed with fasteners (eg, bolts and nuts or rivets).

The reinforcing area 126 is integrally disposed at the center of each fixing area 125 . At this time, the reinforcing regions 126 are arranged to be spaced apart from each other from the outer surface of the first side plate 111 . Accordingly, at one end (upper end in FIG. 5 ) of the fixing part 124 , a fastening area 125a is formed as much as the distance between the reinforcement area 126 and the first side plate 111 . An insertion member 129 to be described later is inserted and coupled to the fastening area 125a.

The fixing part 124 has a frame structure in which the reinforcing areas 126 from the fixing areas 125 on both sides are arranged to be spaced apart from the first side plate 111 and bent. Therefore, the fixing part 124 has the advantage of reinforcing the reinforcing structure compared to the case where the fixing area 125 and the reinforcing area 126 are disposed on one plane. Although not shown in the drawings, the fixing part 124 further reinforces the reinforcing structure by further forming protrusions (not shown) protruding from the reinforcing area 126 or concave recesses (not shown) along the longitudinal direction. may be Of course, protrusions or depressions may be disposed at positions spaced apart from both ends of the reinforcing area 126 so as not to block the fastening area 125a to which the insertion member 129 is to be coupled.

In addition, the coupling part 127 protrudes so as to extend further from the center of the other end of the fixing part 124 and the overlapping member 128 bent in the thickness direction of the first side plate 111 at both sides of the other end of the fixing part. It includes an insertion member (129).

The overlapping member 128 protrudes in a shape corresponding to the bending member 122 . At this time, the overlapping member 128 is combined with the other reinforcing part 120b so as to overlap the ring part 121 of the other reinforcing part 10b.

The insertion member 129 protrudes from the end of the reinforcing area 126 so as to be bent so as to be positioned on the same virtual plane as the fixing area 128 . Therefore, the overlapping member 128 and the insertion member 129 of the first reinforcing part 120a disposed on the upper part are connected to the hook part 121 of the second reinforcing part 120b disposed on the lower part and the fastening area 125a, respectively. is coupled to

At this time, the ring part 121 of the second reinforcement part 120b and the overlapping member 128 of the first reinforcement part 120a are formed along the thickness direction of the second side plate 112 at the upper end of the second side plate 112. while the insertion member 129 of the first reinforcing part 120a is inserted into the fastening area 125a between the outer surface of the second side plate 112 and the reinforcing area 126 of the second reinforcing part 120b. The first side plate 111 and the second side plate 112 are laminated.

The first reinforcement part 120a and the second reinforcement part 120b may be coupled to four sides of the first side plate 111 and four sides of the second side plate 112 , respectively. Alternatively, although not shown in the drawing, a pair of reinforcing parts may be provided on each of the four sides of each side plate so that a total of four pairs of reinforcing parts may be coupled in the vertical direction.

Figure 6 is a cross-sectional view showing a portion of one side plate of the wire-reinforced laminated packaging box shown in Figure 3;

Referring to Figures 4 and 6, the wire-reinforced laminated packaging box (see Figure 1, 100) according to an embodiment of the present invention includes a reinforcing wire 130 inside the first side plate 111.

The reinforcing wire 130 is inserted into the through hole (see FIG. 4 , 10 ) formed along the horizontal direction of the first side plate 111 and is connected to surround four sides of the first side plate 111 . Therefore, the reinforcing wire 130 inserted into the through hole 10 at one end of the first side plate 111 is discharged through the through hole 10 at the other end of the first side plate 111, and both ends of the reinforcing wire 130 By binding the first side plate 111 can be reinforced so that it does not bend while stretching or spreading in the horizontal direction.

In this embodiment, the reinforcing wires 130 are respectively disposed in the first through hole 10a disposed in the center of the first side plate 111, the second through hole 10b disposed in the upper part, and the third through hole 10c disposed in the lower part. ) is provided to reinforce the reinforcing function at equal intervals in the upper region, the central region, and the lower region of the first side plate 111 . Of course, the reinforcing wire 130 may change the arrangement position inside the first side plate 111 or increase or decrease the number of reinforcing wires according to the weight of the stored goods accommodated therein.

For example, as shown in FIG. 5, the reinforcing wire 130 is adjacent to the upper and lower ends of each side plate corresponding to the area where the reinforcing parts 120a and 120b couple the first side plate 111 and the second side plate 112. One or a plurality of through holes 10b and 10c may be provided, respectively. This has an effect of reinforcing a force preventing the combined state of the reinforcing parts from being separated by the weight of the stored object in the region where the first side plate 111 and the second side plate 112 are coupled.

Of course, the reinforcing wire 130 may be simultaneously folded or bent while the side plate portion (see FIG. 1, 110) is folded. For example, the reinforcing wire 130 may be a wire such as piano wire or fishing line made of metal or synthetic resin.

Then, after both ends of the reinforcing wire 130 are connected to each other inside each side plate, each through hole can be shielded as the ends of each side plate (both ends exposed to the outside) are joined.
