Therefore, the beverage container packaging box has the advantage that it is possible to accommodate several products in one packaging box, it is easy to assemble into a packaging box. However, the beverage container packaging box has a simple structure of the box does not support a large load, so if a large number of products are accommodated more, the packaging box may not support the force and may be torn or damaged.

In addition, these packaging boxes can not support the vertical load, which is the force pushing down from the top when loaded up, may collapse the structure of the internal storage space, and if the height of loading the packaging box up, the packaging box is unstable and collapsed There is also a possibility that the packing box may not be loaded high.

In addition, the conventional packaging box is provided with a partition plate manufactured separately inside the packaging box, a number of products are fixed inside the packaging box by the partition plate. However, such a packaging box is difficult to properly manage the separately manufactured partition plate, it is more economically disadvantageous because the fabric of the packaging box is also consumed more than if made integrally. In addition, since the partition plate itself does not support a large force in accommodating the product, it is likely to be torn in the process of taking out or storing the product.

Accordingly, an object of the present invention for solving the above-described problems of the present invention is to provide a packaging box in which a partition plate capable of storing a plurality of products is integrally formed when the packaging box is assembled.

Another object of the present invention is to provide a packaging box having a stable structure even when a plurality of packaging boxes are stacked up.

In addition, another object of the present invention is to provide a packaging box which is simple to assemble and which can stably house a product.

According to a preferred embodiment of the present invention for achieving the objects of the present invention described above, the packaging box has a bottom plate, a side wall portion and a partition portion.

The bottom plate is formed in a rectangular shape and forms the bottom of the packaging box. The side wall portion includes a first side plate, a second side plate, a third side plate, and a fourth side plate sequentially connected to four edges of the bottom plate.

The partition portion forms an incision through a bend line that is a boundary between the bottom plate and the first to fourth side plates, and when the side wall portion is bent perpendicularly to the bottom plate, the partition portion protrudes from the bottom plate to define the inner space. At least one partition is formed, and a storage space is provided between the partition and the partition or between the partition and the side wall to accommodate the goods. The shape of the partition may be manufactured in a circular or various shapes depending on the shape of the product.

In the conventional packaging box, a partition plate for partitioning the inner space of the packaging box is separately manufactured. Accordingly, the partition plate is manufactured to accommodate a plurality of goods, the hole is to position the goods in the storage space, so that it is possible to stably receive the goods inside the packaging box. However, since the partition plate is manufactured separately, the manufacturing cost is high, and the packaging box and the partition plate are not formed integrally, which is cumbersome because they need to be managed separately. However, the packaging box according to the present invention, the compartment is formed integrally with the packaging box. Therefore, there is no need to manufacture the compartments separately, so it is economically advantageous and there is no need to manage them separately, which is convenient for storage and transportation. In addition, since the partition portion disperses the direction of the pressing force from the outside, the strength of the packaging box is increased so that even if a large number of products are accommodated, the structure of the packaging box is stably supported without collapsing the structure or tearing the packaging box.

The packaging box may further include sidewall reinforcement plates connected to both edges of the first and third side plates to reinforce the second and fourth side plates. At this time, the upper edge of each side plate in the first to fourth side plate is formed to be narrower than the lower edge, and by forming the inclined adjacent edges of the second and fourth side plate in the side wall reinforcement plate, the entire side wall portion can be inclined toward the top have. That is, the packaging box is formed in an inclined shape in which the sidewall portion is slightly narrowed in the receiving inlet for receiving the goods on the bottom plate. Therefore, when loading the packaging box formed with the insertion groove in the four corners of the bottom plate up and down, the protrusion of the packaging box can be easily inserted into the insertion groove of the bottom plate, each side wall portion is stable by having a pyramid shape slightly inclined The laminated structure of a packaging box can be formed. In addition, since the lower part of the stacked packing box is partially lifted, the packing boxes can be easily lifted or stacked.

The packaging box according to the present invention is initially fed to the box assembly machine so that the bottom of the packaging box is visible during assembly. And it pushes toward the part bent at the boundary of a partition part and a bottom plate, or a partition part and a side wall part. Therefore, cut lines are formed at the boundary between the partition and the bottom plate. Then, by rotating 180 degrees and seated so that the top of the bottom plate is visible, when assembling the packaging box, the partition is projected to the bottom plate, the packaging box is easily completed. Therefore, it is economically advantageous to automate this process by installing a box assembly device to reduce the manufacturing cost and manufacturing time.

Further, according to another preferred embodiment of the present invention for achieving the above object of the present invention, the packaging box has a bottom plate, side wall portion, top plate and partition.

The bottom plate is formed in a rectangular shape and forms the bottom of the packaging box. The side wall portion includes a first side plate, a second side plate, a third side plate, and a fourth side plate sequentially connected to four edges of the bottom plate. The first to fourth side plates are connected to the four corners of the bottom plate through a bend line. The top plate is connected through the side wall portion and the bend line and covers the internal space provided by the bottom plate and the side wall portion. The partition portion forms an incision through a bend line that is a boundary between the bottom plate and the first to fourth side plates, and when the side wall portion is bent perpendicularly to the bottom plate, the partition portion protrudes into the bottom plate at the boundary to partition the internal space. At least one partition is formed, and a storage space is provided between the partition and the partition or between the partition and the side wall to accommodate the goods. The shape of the partition may be manufactured in a circular or various shapes depending on the shape of the product.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments.

2 is a development view for explaining a packaging box according to a first embodiment of the present invention.

Referring to FIG. 2, the packaging box includes a bottom plate 110, a sidewall part 120, and a partition part 130.

Bottom plate 110 is formed in a rectangular shape and the material is made of cardboard. Corrugated cardboard has a sufficient strength to maintain the structure, while the material itself is relatively soft to cushion external impacts. In addition, it is possible to freely form the desired structure through cutting and bending, and can be stored and transported in a bent state, the logistics cost of the packaging material itself is low, and above all, there is an advantage that it is cheaper to manufacture and purchase. Bottom plate 110 is located on the bottom of the packaging box to support the weight of the product from the bottom. Therefore, although the present invention is manufactured in the size of the bottom plate 110 that can accommodate 10 products, in another embodiment of the present invention may be manufactured in various sizes according to the intention of the designer. And the side wall portion 120 and the partition portion 130 is integrally made of cardboard.

The side wall part 120 includes a first side plate 122, a second side plate 124, a third side plate 126, and a fourth side plate 128. The first side plate 122 is connected to one corner of the bottom plate 110 via a bend line, the second side plate 124 is connected to the adjacent one edge through a bend line, and the third side plate 126 and The fourth side plate 128 is also sequentially connected to the remaining corners of the bottom plate 110. The first side plate 122 and the third side plate 126 are formed to extend in the horizontal axis. Thus, a packaging box extending in one direction can be produced. The side wall portion 120 may be assembled and positioned vertically to the bottom plate 110, and may be deployed when the packaging box is stored and transported to reduce the volume of the packaging box. However, in another embodiment of the present invention, the side wall portion may be fixed perpendicularly to the bottom plate according to the designer's intention.

The partition 130 includes a bend line that is a boundary between the bottom plate 110 and the bottom plate 110, and the first side plate 122, the second side plate 124, the third side plate 126, and the fourth side plate 128. An incision 132 via a bend line is formed to intersect. The cutout 132 is formed such that the first cutout 132a and the second cutout 132b are symmetric with each other, and the partition 130 is disposed between the first cutout 132a and the second cutout 132b. Is bent perpendicularly to the bottom plate 110. Therefore, the partition unit 130 protrudes from the bottom plate 110 to form an accommodation space between the partition unit 130 and the partition unit 130, and supports the product from the left and right of the product, so that the shock generated from the outside of the packaging box This is buffered. In addition, the partition 130 connects the bottom plate 110 and the side wall portion 120, and distributes the direction of the pressing force from the outside, so that the strength of the packaging box is increased, even if a large number of goods are accommodated in the structure collapse or packaging box It stably supports the structure of the packing box without tearing.

Therefore, the packaging box according to the present invention is economically advantageous because the partition 130 is integrally formed inside the packaging box, so that the partition 130 does not need to be manufactured separately. There is no need for convenient storage and transportation.

3 is a partial perspective view for explaining a partition of the packaging box according to the first embodiment. The present invention is suitable for receiving a beverage container.

Referring to FIG. 3, the partition 130 includes a first partition plate 134 and a second partition plate 136. The first partition plate 134 is formed perpendicular to the bottom plate 110 so that one end is connected to the bottom plate 110 and the other end is connected to the second partition plate 136. The second partition plate 136 is formed horizontally on the bottom plate 110, and both ends thereof are connected to the first partition plate 134 and the side wall part 120. Accordingly, when the first to fourth side plates 122, 124, 126, and 128 are bent perpendicularly to the bottom plate 110, the partition 130 is bent in the opposite direction to automatically partition the space, and at the same time, a plurality of partitions are assembled. Part 130 may be made. Thus, the product is stored between the partition 130 and the adjacent partition 130. The side portions of the first partition plate 134 and the second partition plate 136 may be variously cut and formed according to the shape of the product. The cutout 132 passes through the first side plate 122 and the bottom plate 110, and includes eight partitions 130 formed by the cutout 132, and ten items are stored therein. do. However, in another embodiment of the present invention, the number of partitions 130 may be variously manufactured according to the intention of the designer.

Example 2

4 is a perspective view for explaining a packaging box according to a second embodiment of the present invention, Figure 5 is a perspective view of the packaging box according to the second embodiment assembled.

4 and 5, the packaging box includes a bottom plate 210, a side wall portion 220, a side wall reinforcement plate 230, and a partition 240.

The bottom plate 210 is formed in a rectangular shape and the material is made of cardboard, the bottom plate 210 is located on the bottom of the packaging box to support the weight of the product from the bottom. In addition, the side wall portion 220, side wall reinforcement plate 230 and the partition portion 240 is integrally made of cardboard. At four corners of the bottom plate 210, an insertion groove 212 cut in an L-shape is formed to penetrate from the bottom of the bottom plate 210 toward the inner space of the packaging box.

The side wall portion 220 includes a first side plate 222, a second side plate 224, a third side plate 226, and a fourth side plate 228. The first side plate 222 is connected to one edge of the bottom plate 210 via a bend line, the second side plate 224 is connected to the adjacent one edge through a bend line, and the third side plate 226 and The fourth side plate 228 is also sequentially connected to the remaining corners of the bottom plate 210. The first side plate 222 and the third side plate 226 are formed to extend in the horizontal axis. The second side plate 224 and the fourth side plate 228 are formed to be inclined at opposite corners, so that the first side plate 222 and the third side plate 226 are slightly inclined sidewalls in a state perpendicular to the bottom plate 210. Is provided.

The side wall reinforcement plate 230 is connected to both ends of the first side plate 222 and the third side plate 226 via a bend line. The side wall reinforcement plate 230 is positioned adjacent to the second side plate 224 and the fourth side plate 228, and the edge 232 adjacent to the second side plate 224 and the fourth side plate 228 is formed to be inclined. Accordingly, the edge 232 is in contact with the bottom plate 210 when the first side plate 222 and the third side plate 226 are placed perpendicular to the bottom plate 210, and the first side plate 222 and the third side plate 226. The state is slightly inclined than the state perpendicular to the bottom plate 210. In addition, a protrusion piece 234 is formed at an upper portion of a bending line to which the first side plate 222 and the side wall reinforcement plate 230 are connected, and when the packaging box is folded, the L-shaped protrusion piece 234 faces upward. It protrudes. Thus, the protruding piece 234 is inserted into the insertion groove of the other packing box which is loaded on the packing box. Similarly, the protruding pieces 234 are also formed at portions where the third side plate 226 and the side wall reinforcement plate 230 are connected to each other. An end portion of the side wall reinforcement plate 230 is partially cut by a predetermined width. Here, the predetermined width means the height of the partition 240 connected to the second side plate 224 and the fourth side plate 228 from the bottom plate 210. Thus, the cut portion of the sidewall reinforcement plate 230 contacts the partition 240 to support the sidewall reinforcement plate 230 from below. The side wall reinforcement plate 230 is positioned on inner surfaces of the second side plate 224 and the fourth side plate 228 to reinforce the side wall.

The partition 240 is a bend line that is a boundary between the bottom plate 210 and the first side plate 222, the second side plate 224, the third side plate 226, and the fourth side plate 228 sequentially connected to the bottom plate 210 and the bottom plate 210. An incision 242 is formed through it. The cutout 242 is formed such that the first cutout 242a and the second cutout 242b are symmetric with each other, and the partition 240 is disposed between the first cutout 242a and the second cutout 242b. Is bent perpendicular to the bottom plate 210. Accordingly, the bottom plate 210 forms an accommodation space between the partition 240 protruding from the bottom plate 210 and the adjacent partition 240, and the partition 240 supports the goods at the left and right sides of the goods from the outside. It cushions the generated shocks. The partition unit 240 includes a first partition plate 244 and a second partition plate 246. The first partition plate 244 is formed perpendicular to the bottom plate 210 so that one end is connected to the bottom plate 210 and the other end is connected to the second partition plate 246. Both ends of the second partition plate 246 are connected to the first partition plate 244 and the side wall part 220 so as to be horizontal to the bottom plate 210. Accordingly, when the first to fourth side plates 222, 224, 226, and 228 are bent perpendicularly to the bottom plate 210, the first to fourth side plates 222, 224, 226, and 228 are bent in the opposite direction to automatically form the partition 240. A portion of the second partition plate 246 connected to the cutout 242 and the first side plate 222 is cut in a straight line, but the remaining portion is cut in a circular curve to keep the storage space in a circular shape. Therefore, the storage space between the partition 240 and the adjacent partition 240 is suitable for accommodating a circular circular product. Therefore, the product can be completely fixed because it is in close contact with the side of the circular circular product, such as a beverage container, does not move from side to side and does not move back and forth.

In addition, the spacing between the compartment 240 and the adjacent compartment 240 is formed slightly smaller than the circumference of the actual beverage container. Accordingly, when the beverage container is disposed between the partitions 240, the beverage container floats in the air about 5 mm from the bottom plate 210. Therefore, the packaging box can be more effectively buffered by not transmitting the impact generated from the outside directly to the beverage container. However, in another embodiment of the present invention, the spacing between the partitions can be adjusted according to the designer's intention.

The partition unit 240 is easily bent because a ruled line is formed at both ends of the bent line. At this time, a ruled line is formed on the top surface of the bottom plate 210 at the bent lines of the first partition plate 244 and the bottom plate 210, and is bent toward the top of the bottom plate 210, and the second partition plate 246 and the side wall portion are formed. Similarly, a ruled line is formed on the inner surface of the bending line 220 to be bent toward the space on the bottom plate 210. In addition, a ruled line is formed on the bottom of the boundary between the first partition plate 244 and the second partition plate 246 and is bent in a direction opposite to the above direction.

In addition, the area of the first partition plate 244 is smaller than the second partition plate 246 by a predetermined interval and is connected to the central portion of the second partition plate 246. Therefore, the boundary where the second partition plate 246 and the first partition plate 244 meet is the same as the shape of the arrow, so that bending occurs easily at that portion. In addition, the cutout is cut so as to be spaced apart from the boundary of the bottom plate 210 by a predetermined interval so that there is no contact between the bottom plate 210 and the partition 240, and therefore, the bottom plate 210 when bending the partition 240. It is not disturbed by the workforce of the department.

6 is a perspective view for explaining that the packing box according to the second embodiment of the present invention is stacked up.

Referring to FIG. 6, the packaging box may load another packaging box up. At this time, the packaging box is formed in the L-shaped protrusion pieces 234 at the four corners. However, in another embodiment of the present invention, the shape of the protruding piece may be variously manufactured according to the intention of the designer. The protruding piece 234 is stably supported by the structure inserted and inserted into the insertion piece 212 formed at four corners of the bottom plate 210. The second side plate 224 and the fourth side plate 228 are formed to be inclined so that the receiving inlet is narrowed. Therefore, it is formed in a trapezoidal shape so that the protruding piece 234 can be inserted into the insertion piece 212 of another packaging box. In addition, since the lower part of the loaded packing box is partially lifted, it is convenient to lift and move the packing box or to stack it on top of the packing box.

Hereinafter, a ruled line forming method of the cardboard connection portion according to an embodiment of the present invention.

7A to 7C are cross-sectional views illustrating a ruled line forming method according to the present invention.

Referring to FIG. 7A, there is provided a corrugated cardboard 290 including a first plate and a second plate connected to the first plate, the cutout being formed via a boundary of the first and second plates to form a partition. . In addition, the step may include the first uneven portion 292a corresponding to the bent position of both ends of the cutout portion and the second uneven portion 292b corresponding to the internal bending position of the partition portion and having unevenness opposite to the first uneven portion 292a. Provide a die to include. The ruled line member 294 is disposed at a position corresponding to the first concave-convex portion 292a and the second concave-convex portion 292b on the upper side of the cardboard 290 and moves up and down. The first concave-convex portion 292a is a surface tape having a linear groove shape. The first concave-convex portion 292a is formed by adhering on the die 296 to protrude upward by a predetermined length. Thus, when the corrugated cardboard 290 is pressed by the ruled member 296, the periphery of the bend line is slightly bent in the opposite direction, and thus more easily bent in the desired direction. The second uneven portion 292b is formed in a linear protrusion shape to press the lower portion of the cardboard 290. However, in another embodiment of the present invention, the first uneven portion and the second uneven portion may use various materials, and the shape of each is not limited.

Referring to FIG. 7B, the step presses a position corresponding to the first uneven portion 292a and the second uneven portion 292b from the top to the bottom using the ruled member 294. Accordingly, the portion of the cardboard 290 disposed on the first uneven portion 292a provides an upper ruled line on which ruled lines are formed from the upper surface. In addition, the portion of the corrugated cardboard 290 disposed on the second uneven portion 292b provides a lower ruled line on which a ruled line is formed from the lower surface.

Referring to FIG. 7C, the corrugated cardboard 290 having the above-described step is formed with concave ruled lines in contact with the first concave-convex portion 292a, and convex ruled lines are formed in contact with the second concave-convex portion 292b. . Concave ruled line means a ruled line formed concave from the upper surface of the cardboard 290, convex ruled line means a ruled line formed convex from the upper surface of the cardboard (290). Therefore, since the cardboard 290 is easily bent toward the ruled line (ⓐ), when an external force is applied to the outside, the corrugated sheet 290 is bent only at a portion where a concave ruled line and a convex rule line are formed, and the cardboard is automatically shaped into a Ｗ-shaped shape along the ruled line. Is bent.

As described with reference to FIGS. 7A to 7C, a ruled line may be formed by the surface of the body plate for manufacturing the packaging box according to the second embodiment.

The above-described ruled line forming method and a manufacturing method of a packaging box can be used to manufacture another packaging box according to the present invention.

Firstly, there is provided a body plate comprising a bottom plate and a side wall plate connected to an edge of the bottom plate, and a partition portion defined by an incision through a boundary between the bottom plate and the side wall plate. Then, the body plate is placed on a die including a first uneven portion corresponding to the bent position of both ends of the partition portion and a second uneven portion corresponding to the internal bending position of the partition portion and having unevenness opposite to the first uneven portion. The body board for manufacturing a packaging box can be prepared by pressing the position corresponding to a 1st uneven part and a 2nd uneven part using a member.

The first uneven portion may be formed as a linear groove to form a concave ruled line at a position corresponding to the bending position of both ends of the partition portion, and the second uneven portion may be formed as a linear protrusion to form a convex ruled line corresponding to the internal bending position of the partition portion. have. In this case, the incision may be formed as thin as a line or wider to have a predetermined width. In particular, in the case of being formed wide, since the partition portion can be bent without friction around, it can be easily bent around the concave ruled line and the convex ruled line.

The partition includes a first partition plate perpendicular to the bottom plate and a second partition plate vertically connected to the side wall plate. The bottom plate-first partition plate-second partition plate-side wall plate is connected to the concave ruled line, the convex ruled line, and the concave ruled line, respectively.
