Description

Prefabricated transport packaging box {TRANSPORT TYPE PACKAGE BOX}

The present invention relates to a prefabricated transport packaging box, and more particularly, to a prefabricated transport packaging box that is easy to use and store because it can be assembled and disassembled, is strong in external impact, and has excellent durability.

In general, when a heavy cargo is to be transported over a long distance using a ship or an aircraft, a standard size container is used.

This packaging box for transport is provided with a pallet to transport heavy cargo, and is configured to include a box-shaped sleeve for protecting the cargo loaded on the pallet.

However, the conventional packaging box for transport has a problem in that the arm and the sleeve are integrally configured or the sleeve is configured to maintain the box shape, so it has a large volume and occupies a lot of space during transportation and storage.

In order to solve this problem, a prefabricated transport box that can reduce the volume by disassembling it for storage and assembling when packing cargo has been developed.

A typical prefabricated transport box includes a pallet on which cargo is loaded, a box-shaped frame surrounding the cargo loaded on the pallet, and a cover covering the upper portion of the frame. At this time, the pallet, frame and cover are manufactured as separate parts so that they can be assembled and used or disassembled and stored as needed.

However, since the conventional prefabricated transport box is made of polypropylene (PP), there was a risk of being easily damaged when it comes into contact with the fork of a forklift during the transport process or when it falls to the floor or comes into contact with other transport boxes during the loading process.

In particular, in the winter when the temperature is low, there is a risk of being easily damaged by a small impact and contact, and there is a problem that the entire pallet and cover must be replaced even if partially damaged.

An embodiment according to the present invention will be described in detail with reference to the accompanying drawings. Hereinafter, in describing the embodiment according to the present invention, and in adding reference numerals to the components of each drawing, the same reference numerals are added to the same components even though they are indicated in different drawings as much as possible.

1 and 2, the packaging box 10 for prefabricated transport according to an embodiment of the present invention includes a pallet 100 on which cargo is loaded, a sleeve 200 surrounding the loaded cargo, and a sleeve It is configured to include a cover 300 covering the open upper part of the 200, and sheets 400 and 500 for protecting the loaded cargo.

At this time, the pallet 100, the sleeve 200, and the cover 300 constituting the packaging box 10 for prefabricated transport are coupled in a fitting manner so that they can be assembled or disassembled according to the user's needs.

Let's take a closer look at each of the components 100 to 500 of the prefabricated transport packaging box 10 (hereinafter referred to as 'packaging box') according to the present embodiment.

As shown in FIG. 3 , the pallet 100 is a component that forms the bottom of the prefabricated transport packaging box 10 , and includes an upper panel 110 , a lower panel 120 , and a connecting column 130 .

The upper panel 110 and the lower panel 120 are rectangular plates having different thicknesses, and in this case, the upper panel 110 on which the cargo is directly loaded is formed to be thicker than the lower panel 120 .

The connecting pillar 130 is a pillar connecting the upper panel 110 and the lower panel 120, and a corner pillar 132 formed at each corner of the panels 110 and 120, and an intermediate pillar formed between the corner pillars 132 ( 134). At this time, a lift hole 190 into which a fork (not shown) of a forklift is inserted is formed between the corner pillar 132 and the intermediate pillar 134 .

A plurality of through holes 140 and 150 are formed in the upper panel 110 and the lower panel 120 . When the through-holes 140 and 150 are formed in the upper panel 110 and the lower panel 120 , the pallet 100 can have a certain strength, and at the same time, the weight can be minimized.

The through-hole 140 formed in the upper panel 110 is a first through-hole 142 formed in an area corresponding to the connecting pillar 130 and a second through-hole formed in an area between the connecting pillar 130 . It is composed of a 144 and a third through hole 146 formed in other regions. At this time, the first through hole 142 is formed to be relatively larger than the second through hole 144 , and the second through hole 144 is formed to be relatively larger than the third through hole 146 .

In this way, when the through-holes 140 are formed in different sizes for each area of the upper panel 110 , uniform strength can be obtained over the entire area of the upper panel 110 . Accordingly, it is possible to prevent the upper panel 110 from being partially damaged by an externally applied load and/or impact.

On the other hand, the through-hole 150 formed in the lower panel 120 is a first through-hole 152 formed in an area corresponding to the connecting pillar 130 and a second through-hole formed in an area between the connecting pillar 130 . Consists of a through hole (154). In addition, a seating hole 156 into which the second protrusion 350 of the cover 300 to be described later is inserted is formed in the other area. In this case, the first through hole 152 is formed to be relatively larger than the second through hole 154 , and the second through hole 154 becomes smaller toward the outside of the lower panel 120 .

Meanwhile, ribs 160 for reinforcing the strength of the pallet 100 are formed around the upper panel 110 . The ribs 160 are arranged densely from the middle of the upper panel 110 toward the edge. In particular, at least three or more are formed at the corners of the upper panel 110 and are radially arranged.

As such, when the ribs 160 are arranged more densely toward the edge of the upper panel 110 , the strength of the edge of the pallet 100 can be increased. Therefore, even if the packaging box 10 falls to the floor in the process of transporting or loading, it is possible to prevent the edge portion of the pallet 100 from being damaged.

For example, the pallet 100 of the above-described structure is not easily damaged even if it falls from a height of about 2 m with a load of -18 degrees below zero, 600 kg, and in particular, it can effectively prevent the corner portion of the pallet 100 from being damaged. .

In this embodiment, although the rib 160 is illustrated as having a plate shape extending up and down, it is not necessarily limited thereto, and may be manufactured in various shapes such as a + shape or an X shape if necessary.

A mounting groove 170 for assembling the sleeve 200 is formed in the upper panel 110 . The mounting groove 170 extends along the circumference of the upper surface of the upper panel 110 to form a ring shape.

As shown in FIG. 4 , the mounting groove 170 has a tapered shape that becomes narrower toward the bottom. In more detail, it has a multi-stage tapered shape comprising a first mounting groove 172 formed on the upper portion and a second mounting groove 174 formed on the lower portion.

At this time, the first mounting groove 172 is formed with a relatively wide width, the second mounting groove 174 is formed with a relatively narrow width, the first mounting groove 172 is wider than the second mounting groove 174 . It is formed more than twice as deep. In addition, the second mounting groove 154 is deviated to the outside of the pallet 100 from the center of the width direction of the first mounting groove 152, for example, to be located at 2/3 of the width direction of the first mounting groove 152. can

As in this embodiment, when the mounting groove 170 has a multi-stage tapered shape, the sleeve 200 can be easily assembled or disassembled, and since the sleeve 200 is inserted to a certain depth or more, the sleeve 200 can be firmly and supported. can

In addition, when the first mounting groove 172 is formed deeper than the second mounting groove 174, it is possible to improve the resistance to the load applied in the horizontal direction, and the second mounting groove 174 is the pallet 100. If it is deviated to the outside of the sleeve 200 may increase the resistance to the load applied from the outside.

A support protrusion 180 is formed on the upper panel 110 to prevent the sleeve 200 fitted into the mounting groove 170 from being overturned. The support protrusion 180 includes a corner protrusion 182 formed at each corner of the upper panel 110 and an intermediate protrusion 184 formed between the corner protrusions 182 .

As shown in FIG. 5 , the sleeve 200 is a component that forms the wall of the prefabricated packaging box 10 for transport, and has a rectangular pipe shape with upper and lower surfaces open. That is, the sleeve 200 includes a pair of long sidewalls 210 positioned to face each other and a pair of short sidewalls 220 connecting the pair of long sidewalls 210 .

The sleeve 200 made of the long side wall 210 and the short side wall 220 has a folding structure so that it can be opened and used or folded and stored according to the user's needs. To this end, a first folded portion 230 is formed between each corner of the sleeve 200, that is, between the long side wall 210 and the short side wall 220, and a second folded portion 240 is formed at the middle of the long side wall 210. is formed

Referring to FIG. 6 , the first folding part 230 includes a pair of first triangular grooves 232 and 234 respectively formed on the inner and outer surfaces of the sleeve 200 . The pair of first triangular grooves 232 and 234 are formed in an approximately equilateral triangle and are positioned to correspond to each other.

When the long-side sidewall 210 and/or the short-side sidewall 220 is rotated around the first folding part 230 , the sleeve 200 may be expanded into a rectangular pipe shape or folded into a plate shape.

Referring to FIG. 7 , the second folding part 240 includes second triangular grooves 242 and 244 formed on inner surfaces of a pair of long sidewalls 210 . The second triangular grooves 242 and 244 are formed in a substantially equilateral triangle and are formed of a pair positioned adjacent to each other.

When the long side wall 210 is rotated around the second folding unit 240 , the long side wall 210 may be unfolded in a plate shape or the long side wall 210 may be folded in two layers.

On the other hand, the second folding parts 240 respectively formed on the pair of long sidewalls 210 are shifted from each other in the longitudinal direction of the long sidewalls 210, which is a pair of folds when the long sidewalls 210 are folded in two layers. This is to prevent the second folding parts 240 from contacting each other, and through this, the volume when the sleeve 200 is folded can be minimized.

8 shows a modified example of the second folding part 240 among the folding parts 230 and 240 according to the present embodiment.

The second folding portion 240m includes second triangular grooves 242a, 244a and 242b, 244b formed on the inner surfaces of the pair of long sidewalls 210a and 210b. At this time, the second triangular grooves 242a, 244a, and 242b, 244b forming the second folding part 240m are equilateral triangles of different sizes, and are located adjacent to each other.

As shown in the drawing, the second triangular groove 242a located at the upper part of the second triangular grooves 242a and 244a formed in the first long side wall 210a is formed relatively large and a second triangular groove located at the lower part. The groove 244a is formed to be relatively small.

On the other hand, among the second triangular grooves 242b and 244b formed in the second long side wall 210b, the second triangular groove 242b located at the upper portion is formed to be relatively small, and the second triangular groove 244b located at the lower side is relatively large.

As such, when the pair of second triangular grooves 242a, 244a and 242b, 244b are formed to have different sizes, the position of the second foldable portion 240m is different when the pair of long sidewalls 210a and 210b are folded. contradict each other Accordingly, it is possible to prevent the pair of second folding parts 240m from coming into contact with each other, and it is possible to minimize the volume when the sleeve 200 is folded.

On the other hand, a mounting projection 250 inserted into the mounting groove 170 of the pallet 100 protrudes from the lower end of the sleeve 200 . The mounting protrusion 250 has a shape corresponding to the mounting groove 170 so that it can be fitted into the mounting groove 170 .

As shown in FIG. 4 , the mounting protrusion 250 has a multi-stage tapered shape that becomes thinner toward the bottom, and includes a relatively thick first mounting protrusion 252 and a relatively thin second mounting protrusion 254 . .

At this time, the first mounting protrusion 252 is formed to be twice as long as the second mounting protrusion 254 , and the second mounting protrusion 254 is at the center of the first mounting protrusion 252 , outside the sleeve 200 . is biased to

In addition, a first protrusion 340 protruding upward and a second protrusion 350 protruding downward are formed on the upper plate 310 . The first projection 340 is to prevent another packaging box (not shown) stacked on top of the packaging box 10 from sliding, and the second projection 350 is to withstand the load applied in the vertical direction. .

The side plate 320 protrudes further downward than the upper plate 310 so as to surround the sleeve 200 assembled in the insertion groove 330 . In this way, when the side plate 320 is formed to be long, the coupling between the sleeve 200 and the cover 300 can be strengthened.

A baffle 360 and ribs 370 for reinforcing the strength of the cover 300 are formed on the upper plate 310 and the side plate 320 . The baffle 360 prevents the cover 300 from being deformed by a load applied in the vertical direction, and the rib 370 prevents the cover 300 from being deformed by a load applied in the horizontal direction. In this case, the baffles 360 are arranged in a grid shape along the lower surface of the upper plate 310 , and the ribs 370 are arranged at equal intervals along the side plate.
