Description

Technical Field

[0001] The present invention relates to a connected packaging box.

Background Art

[0002] It is sometimes the case that different products are combined and sold, or that prizes are attached to products and sold. For example, shampoo and conditioner are each placed in separate packaging boxes, which are integrally connected and sold, or a packaging box containing a prize such as a promotional item is integrally connected to a packaging box containing a product so that they do not become separated and sold.

[0003] As such a connected packaging box, there is a packaging connected box in which one side surface portion of a packaging box (A) is opposed to one side surface portion of a packaging box (B), and a protruding piece of the packaging box (B) is inserted into a gap between the upper edge of one side surface portion of the packaging box (A) and the upper lid portion, thereby connecting and holding both of them detachably (Patent Document 1).

[0004] In this packaging connected box, the packaging box (A) is a box body assembled from a single sheet into a rectangular parallelepiped shape, and includes a rectangular tube portion composed of a front surface portion, a back surface portion, and left and right side surface portions, an upper lid portion that covers the upper opening of the rectangular tube portion, and a lower lid portion that covers the lower opening of the rectangular tube portion. The packaging box (B) is a box body assembled from a single sheet into a substantially rectangular parallelepiped shape, and includes a rectangular tube portion composed of a front surface portion, a back surface portion, and left and right side surface portions, an upper lid portion that covers the upper opening of the rectangular tube portion, and a lower lid portion that covers the lower opening of the rectangular tube portion. The shapes of the left and right side surface portions of the rectangular tube portion are set to be the same as the shapes of the left and right side surface portions of the rectangular tube portion of the packaging box (A), and a protruding piece that protrudes outward by a predetermined width is formed from the upper edge of one of the left and right side surface portions.

[0005] In this packaging connected box, since only the protruding pieces that protrude outward from the upper edge of one of the left and right side surface portions are used for connection, there is a risk that the connection may easily come off.

[0006] To prevent this, methods such as reinforcing the connection between box 1 and box 2 with adhesive tape, or securing the top and bottom lids with tape or adhesive to prevent them from opening, as shown in Figure 9, are sometimes used, but this makes the packing process more time-consuming.

Embodiments for Carrying out the Invention

[0018] Hereinafter, embodiments of the present invention will be described in detail while referring to the drawings. The present invention is not limited to the embodiments described below. Also, in the embodiments shown below, technically preferable limitations are made for carrying out the invention, but this limitation is not an essential requirement of the present invention.

[0019] FIG. 1 is an external view of one form of packaging box A and packaging box B of the connected packaging box of the present invention. The connected packaging box of the present invention is composed of a large packaging box A and a small packaging box B when compared with each other. Packaging box A and packaging box B are appropriately designed according to the size, quantity, and weight of the items to be packaged, and are not particularly limited, but are typically formed by folding a sheet material having strength and processability such as cardboard or thick paper and appropriately bonding it. Packaging box A and packaging box B may be composed of the same material or different materials.

[0020] Packaging box A can be made larger to accommodate and package the goods. The goods are not particularly limited, but may be a single item or a group of items. Examples of single items include electrical and electronic equipment, while examples of group items include metal or paper cans filled with beverages such as milk, juice, soft drinks, and beer.

[0021] Packaging box B is made relatively small and connected to packaging box A. Preferably, the height of packaging box B is equal to or less than the height of packaging box A. The items to be packaged are not particularly limited, but examples include accessories for the items packaged in packaging box A, and promotional items for the items packaged in packaging box A.

[0022] Packaging box A is formed by folding a sheet material into a rectangular tube shape, creating a top surface 24, a bottom surface 25, and left and right sides 26a and 26b. The direction from the bottom surface 25 to the top surface 24 and the reverse direction are defined as the up and down direction. The length in the up and down direction of a box or item is also called the height. Corresponding to the up and down direction, the left and right, front and back directions are defined according to general technical common sense. The front and back sides, which are the open sides, are sealed after the item is placed inside by folding in the left and right flaps 22a and 22b on the front side, and then folding in the top and bottom flaps 21a and 21b and sealing them as appropriate to form a box shape. The back side is sealed in the same way.

[0023] The sizes of the left and right flaps 22a, 22b and the top and bottom flaps 21a, 21b are set to a size that provides sufficient strength to the box when folded and glued, while avoiding waste of resources and costs. Generally, they are not made large enough to completely cover the front. In this embodiment, the left and right flaps 22a, 22b cover a portion of the front. The top and bottom flaps 21a, 21b are sized to create a small gap 23 when folded. Therefore, the gap 23 is formed to extend horizontally. This is to absorb processing variations that may occur in the corrugated cardboard or thick paper material, and also to allow fingers to be inserted into the gap 23 when opening the box, making it easier to open.

[0024] In the connected packaging box of the present invention, packaging box A and packaging box B are connected using this gap 23. Packaging box B is formed by folding a blank 10, as shown in Figure 2, along the dashed line and assembling it, and then gluing it together as appropriate. A first protruding piece 12 protrudes from one side of the portion 11b that will become the box body 11 of the blank 10, and a second protruding piece 13 is attached to the tip of the first protruding piece 12. The width W of the protruding piece is set to a width that can be inserted into the gap 23. The respective protruding lengths P1 and P2 will be described later.

[0025] This blank is assembled into a box shape, and as shown in the lower part of Figure 1, a first protruding piece 12 is bent and protruded from one side 14 of the box body 11 so as to extend downward along one surface 16 of the box body 11, and a second protruding piece 13 is formed by folding back at the folded portion 15 at the tip of the first protruding piece 12 so as to extend upward on the opposite side. Packaging box A and packaging box B are connected by inserting these first protruding piece 12 and second protruding piece 13 into the gap 23 so as to face packaging box A. Thus, one surface 16 becomes the surface facing packaging box A.

[0026] Figure 3 is a perspective view of one form of packaging box A and packaging box B, taken from the direction of arrow X in Figure 1. There is a gap 23 between the upper and lower flaps 21a and 21b of packaging box A, and narrow spaces 23a and 23b extending vertically are formed inside this gap. This is due to the thickness of the side flaps 22a and 22b that are inside the upper and lower flaps 21a and 21b and do not cover the entire front surface, as well as the slight gap between the items stored inside and the box. Packaging box B has a first protruding piece 12 extending downward from one side 14 in a direction along the box body 11, and a second protruding piece 13 that is folded back at the folded-over part 15 extending upward. However, in the diagram, the respective protruding pieces are shown slightly apart for clarity.

[0027] Figure 4 is an explanatory diagram of how packaging box B is connected to packaging box A. First, the second protruding piece 13 of packaging box B is inserted into the space 23a formed above packaging box A, i.e., in the second direction. Once the folded portion 15 reaches the gap 23, it becomes possible to insert the folded portion 15 into the space 23b formed downwards, i.e., in the first direction. By inserting the first protruding piece 12 into space 23b, packaging box A and packaging box B are connected to form a connected packaging box 1. Since the first protruding piece 12 extends downwards in the direction along the box body 11, packaging box A and packaging box B become an integrated entity. In this way, by inserting the respective protruding pieces in two directions, the protruding pieces are held in two places, allowing for easy and secure connection.

[0028] In this case, as mentioned above, if the height of packaging box B is equal to or less than the height of packaging box A, then when the bottom surface 25 of packaging box A and the bottom surface 19 of packaging box B are inserted until they are at approximately the same height, packaging box B will not get in the way even if multiple packaging boxes A are stacked, which is more preferable.

[0029] As described above, when packaging box A and packaging box B are connected, the protrusion lengths of each protrusion (P1 and P2 in Figure 2) should be appropriately set so that the second protrusion 13 is held in space 23a and the first protrusion 12 is held in space 23b. When the first protrusion 12 and the second protrusion 13 are inserted into the narrow spaces 23a and 23b, the frictional resistance that naturally occurs between the materials constituting packaging box A and packaging box B holds packaging box B in place in both spaces, making it difficult for it to fall out, and packaging box B becomes almost fixed. Therefore, even if packaging box B is shaken vertically during normal transport or display, there is little risk of packaging box B shifting or falling out.

[0030] Figure 5 is a side view of a modified form of packaging box B. In this example, the first protruding piece 12 is adhered or glued to one surface 16 of the opposing box body 11 near its upper part 17, i.e., one side 14. As a result, the first protruding piece 12 is less likely to separate from the surface 16, and is more strongly fixed to packaging box A when connected to it. Also, the lower flap 21b can only be inserted up to the part where the first protruding piece 12 is not adhered or glued, i.e., up to height H. This ensures that the bottom surface 25 of packaging box A and the bottom surface 19 of packaging box B are aligned by matching the height H with the height of the lower flap 21b, and conversely, packaging box B cannot move any further downward relative to packaging box A, further reducing the risk of packaging box B shifting or falling out. Furthermore, there is no particular problem even if the height of packaging box B is greater than height H.

[0031] Figure 6 is a side view of a second modified example of packaging box B connected to packaging box A. In this example, the height of packaging box B is made equal to the height of the lower flap 21b. By doing this, when packaging box A and packaging box B are connected as described above, if the first protrusion 12 is inserted to the point where the bottom surface 25 of packaging box A and the bottom surface 19 of packaging box B are at the same height, the lower flap 21b will enter up to the vicinity of the side 14 from which the first protrusion 12 protrudes, and it will not be possible to insert it any further, making it easy to align the bottom surface 25 of packaging box A and the bottom surface 19 of packaging box B. In addition, there is no need to separately bond or adhere the upper part of the first protrusion 12 to one side 16.

[0032] Figure 7 is a perspective view of a third modified example of one form of packaging box B. In this example, double-sided adhesive tape 18 is applied to the surface of packaging box B that directly faces packaging box A when packaging box B is connected to packaging box A. When the first protruding piece 12 and the second protruding piece 13 are inserted into the gap and connected, the double-sided adhesive tape 18 is used to further adhere packaging box B to packaging box A, making it even more difficult for packaging box B to detach or shift even when large forces are applied during display or transportation of the connected packaging boxes. There are no particular restrictions on the position where the double-sided adhesive tape is applied, as long as it is on the surface that directly faces packaging box A when connected. For example, it may be on the first protruding piece 12 as in Figure 7(A), or on one surface 16 of the box body 11 as in Figure 7(B), or it may be applied to both.

[0033] Figure 8 is a side view of packaging box B connected to packaging box A. Packaging box B has a first protruding piece 12 and a second protruding piece 13 that are inserted into the gap 23, and is attached to the upper flap 21a or lower flap 21b with double-sided adhesive tape 18. In the example shown in Figure 8(A), the double-sided adhesive tape 18 is applied to the first protruding piece 12, so the first protruding piece 12 is attached to the upper flap 21a, making it less likely for the protruding piece inserted into the gap 23 to fall out of the gap 23, and also deterring intentional removal. On the other hand, in the example shown in Figure 8(B), the double-sided adhesive tape 18 is applied to one surface 16, so the one surface 16 is attached to the lower flap 21b, and packaging box B is fixed at both the upper and lower ends, so that the lower end of packaging box B in particular does not swing around.

[0034] As described above, the connected packaging box of the present invention allows two packaging boxes to be connected without effort by inserting two protruding pieces into the gap in two directions, and there is no risk of the attached packaging boxes falling off during display or handling. Furthermore, a connected packaging box is obtained that does not require time-consuming fixing methods such as taping. [Explanation of Symbols]
