JP7492447B2 - Packaging box - Google Patents

Description

The present invention relates to a packaging box for bottle containers such as PET beverage bottles, and in particular to a packaging box that allows easy removal of the bottle containers when inserting them into a vending machine, etc.

Conventionally, as disclosed in Patent Document 1, for example, packaging boxes are known that take into consideration the ease of loading bottle containers, such as PET bottles containing beverages, into vending machines.

Patent Document 1 discloses a configuration for so-called A-type cartons (set-up cardboard boxes) that improves the efficiency of the work of inserting bottle containers into vending machines. Specifically, the packaging box is stood upright with the short side panels (narrow side surfaces) that make up the peripheral walls facing upward (top), and a cutting tape is pulled from an H-shaped cut to cut and open the short side panels, allowing the bottle containers to be removed from the top.

JP 2002-166927 A

In the configuration disclosed in Patent Document 1, only the H-shaped cut is provided in the short side panel, so when opening the package with the short side panel facing up, it is necessary to first insert fingers into the H-shaped cut and pull the cutting tape horizontally to the left and right ridges, and then break the ridges that extend perpendicular to the opening to open the package.

In this case, pulling the cutting tape to the left and right requires a firm grip with the fingers and a strong pull, and because it needs to be pulled in both directions, it is difficult to do with one hand and places a strain on the worker. In addition, after pulling the cutting tape, the worker is forced to tear the ridge (the boundary between adjacent side panels), which also places a large strain on the worker.

In view of the above, the present invention proposes a new technology that allows packaging boxes for bottle containers to be easily opened and reduces the burden on workers when opening them.

The problem that the present invention aims to solve is as described above, and the means for solving this problem will be explained next.

In one embodiment of the present invention, a packaging box is provided having a peripheral wall formed by alternately arranging four side panels, and a box shape formed by closing flaps connected to each side panel,
At least one side panel has
a zipper line extending obliquely downward from the position of the handle located at the upper end of the left-right center of the side panel toward the fold extending in the up-down direction at the left and right edges of the side panel, and extending downward along the fold after reaching the fold;
The packaging box has a side flap which is opened by pulling up the handle and breaking the zipper line.

In one embodiment of the present invention, the inclined line portion of the zipper line that extends diagonally downward from the center of the left and right sides of the side panel is positioned at a position shifted upward from the center in the vertical direction of the side panel.

In one embodiment of the present invention, the inclined line portion of the zipper line near the fold is made up of a small through line that is shorter in length than other portions.

In one embodiment of the present invention, a corner portion is formed in the side panel in the area opposite the side flap across the inclined line portion, and the corner portion remains when the side flap is open.

In one embodiment of the present invention, the side panels are configured to form a peripheral wall by alternately connecting narrow short side panels and wide long side panels,
The narrow side panels have zipper lines and side flaps.
With the packaging box held upright, the short side panels are positioned at the top, and the side flaps are pulled up to form an opening.
The packaging box is configured so that the contents can be removed from the top.

In one embodiment of the present invention, the side flaps can be flipped up and pulled up to open the packaging box, reducing the burden on the worker who opens the box.

In addition, in one embodiment of the present invention, a wide opening can be formed after the side flap is opened, making it easy to remove bottle containers and other items stored in the packaging box.

In addition, in one embodiment of the present invention, the continuity of the zipper line can be maintained to ensure ease of opening. In addition, the strength of the surrounding areas can be maintained, and the so-called bulging (lateral deformation caused by the packaging box being crushed) during stacking (when the packaging boxes are stacked) can be suppressed.

In addition, in one embodiment of the present invention, the corners function as reinforcing parts, ensuring the rigidity of the packaging box after it has been opened.

In addition, in one embodiment of the present invention, for example, when inserting a bottle container into a vending machine, it is possible to hold the packaging box with the left arm, open the side flap with the right hand, and then insert the bottle container with the right hand, thereby shortening the operation time and improving efficiency.

FIG. 4 is a diagram showing a blank state before assembly of a packaging box. FIG. FIG. 4 is a diagram showing the configuration of a short side panel. 1A is a diagram showing the packaging box in a vertical orientation, and FIG. 1B is a diagram showing the packaging box in a side flap open state. FIG. 13 is a diagram showing the packaging box in a landscape orientation with the side flaps folded forward and open.

The following describes an embodiment of the present invention with reference to the attached drawings. For ease of explanation, the positional relationship is basically specified based on the up/down and left/right directions shown by the arrows in Figure 1.

This packaging box is made of a cardboard blank as shown in Figure 1, in which a pair of narrow short side panels 1, 1 and a pair of wide long side panels 2, 2 are alternately connected via folds 8. A joint panel 3 is connected to the outer edge of one of the short side panels 1.

Flaps 4, 5 are connected to the upper and lower edges of each short side panel 1 and each long side panel 2. Folds 31, 32 are formed at the connection points.

As shown in Figure 2, the short side panel 1 and the long side panel 2 of the blank described above are folded into a rectangular tube shape, and a joining panel 3 (Figure 1) is attached to the back surface of one of the short side panels 1 to form a peripheral wall, and the flaps 4 and 5 are folded inward to form a packaging box 50.

As shown in Figures 1 and 2, a handle hole cutout 11 is formed in each short side panel 1, and the handle hole is opened by pushing a finger into the handle hole cutout 11 and pushing the small piece inward.

As shown in Figure 1, each short side panel 1 has an H-shaped notch 13 formed in it. By inserting your fingers into the H-shaped notch 13 and folding the gripping portion towards you while pulling it sideways, the internal cut tape is pulled up, causing each short side panel 1 to break, allowing it to be separated into upper and lower parts.

Similarly, each long side panel 2 has an H-shaped notch 21 formed in it, and by inserting your fingers into the H-shaped notch 21 and folding the gripping portion towards you while pulling it sideways, the internal cut tape is pulled up and each long side panel 2 breaks, allowing it to be separated into upper and lower parts.

FIG. 3 is a diagram showing the structure of the short side panel 1. As shown in FIG.
This short side panel 1 is positioned on the upper side when the packaging box 50 is upright, as shown in FIG. 4(A), and is configured so that it can be opened as shown in FIG. 4(B) to easily remove the bottle container 40 inside.

As shown in FIG. 3, the short side panel 1 is provided with a push-in piece 12 at a position along the top end of the short side panel 1 in the left-right center, which is pushed inward to form a handle 19. The push-in piece 12 is surrounded by a fold 12a extending horizontally and a number of arc-shaped through lines 12b that bulge downward from the left and right ends of the fold 12a. The fold 12a forms part of a fold 31 that extends horizontally at the top end of the short side panel 1.

As shown in Figure 3, the arc-shaped through-line 12b is positioned close to the upper end of the short side panel 1, so that when a load acts from above during stacking (when the packaging boxes are stacked), the load can be absorbed by the through-line 12b, and the so-called bulging (lateral deformation caused by the packaging box being crushed) can be suppressed.

As shown in FIG. 3, zipper lines 14, 14 are formed on the short side panel 1, extending diagonally downward to the left and right from the left and right ends of the fold 12a of the push-in piece 12. The zipper line 14 is configured to bend downward at the fold 8 that is the boundary between the short side panel 1 and the long side panel 2, and extend along the fold 8 to a position that reaches the lower end of the short side panel 1. In the zipper line 14, the portion between the fold 12a of the push-in piece 12 and the fold 8 is the inclined line portion 14a, and the portion disposed in the vertical direction along the fold 8 is the vertical line portion 14b.

The zipper line 14 may be provided on at least one of the two short side panels 1 shown in Figure 1.

As shown in FIG. 3, in the zipper line 14, the boundary 14c between the inclined line portion 14a and the upper and lower line portions 14b is located above the center in the vertical direction of the short side panel 1. In this embodiment, it is located about 1/6 of the way from the top in the vertical direction of the short side panel 1. This ensures a wide range for the upper and lower line portions 14b, and as will be described in more detail later, it is possible to ensure a wide opening 52 (FIG. 4(B)) when the side flap 16 is opened.

The zipper line 14 is constructed by arranging approximately L-shaped through-lines 15a at equal intervals, and when force is applied, the areas between the through-lines 15a break, causing the zipper line 14 to break continuously.

As shown in FIG. 3, the side flap 16 is defined by the area of the short side panel 1 that is surrounded by the zipper line 14, the fold 12a of the push-in piece 12, and the lower fold 32.

As shown in FIG. 1, the transition plate 3 has a similar zipper line 17 at a position corresponding to the zipper line 14, and when the side flap 16 to which the transition plate 3 is attached is opened, the zipper line 17 formed on the transition plate 3 breaks. The side flap 16 can also be opened by peeling off the glued portion between the side flap 16 and the transition plate 3 without breaking the zipper line 17.

In the above configuration, as shown in Figure 4 (A), while the short side panel 1 is facing up, the push-in piece 12 is pushed inward to open the handle portion 19, and then the side flap 16 is pulled upward from the inside in the direction of the arrow F1 with the fingers. This causes the zipper line 14 to break continuously toward the inclined line portion 14a and the upper and lower line portions 14b, and as shown in Figure 4 (B), the side flap 16 is pulled up and opened, and the packaging box 50 is opened.

By opening the side flap 16, a wide opening 52 for removing the bottle container 40 is formed on the upper side of the packaging box 50, and the bottle container 40 can be removed from the top through the opening 52.

The opening operation can be performed with a single action, i.e., by pushing the push-in piece 12 inward and then pulling it up, which reduces the burden on the worker who opens the packaging box 50.

In addition, since the packaging box 50 can be opened with one hand, for example, when inserting a bottle container 40 into a vending machine, the user can hold the packaging box 50 in the left arm, open the side flap 16 with the right hand, and then insert the bottle container 40 with the right hand, thereby shortening the operation time and improving efficiency.

The opening 52 is formed by opening the side flaps 16, but the triangular corner portion 18 remains above the inclined line portion 14a. The presence of the corner portion 18 in this way allows it to function as a so-called reinforcing portion, ensuring the rigidity of the packaging box 50 after it has been opened.

By ensuring the rigidity of the packaging box 50 after opening, for example, the packaging box 50 can be lifted stably without deformation. Even if the number of bottle containers inside is reduced and the free space inside increases, deformation such as crushing of the packaging box 50 can be prevented, and the box shape can be maintained.

In particular, when replenishing products in vending machines, it is expected that the replenishing will be carried out by moving between multiple locations, and it is expected that after opening a packaging box at one location, not all bottle containers will be replenished, and the opened packaging box will be loaded onto a truck or the like and moved. For this reason, the packaging box needs to be stable in shape after opening, and in this regard, ensuring rigidity by the corner portions 18 is effective.

In addition, in the inclined line portion 14a of the zipper line 14, near the fold 8, instead of the approximately L-shaped through line 15a, a small straight through line 15b that is shorter than the other through lines 15a is arranged.

In this way, by placing a short small through line 15b near the fold 8, the continuity of the zipper line 14 is maintained to ensure ease of opening, and the rigidity against so-called bulging (lateral deformation caused by the packaging box being crushed) during stacking (when the packaging boxes are stacked) can be increased.

In the embodiment described above, the side flaps 16 are formed on the short side panels 1 that make up the peripheral wall, but they may be provided on the long side panels 2 instead of the short side panels 1, or on both the short side panels 1 and the long side panels 2. Also, the side flaps 16 may be provided on only one of the four side panels, or all of the side panels may have side flaps 16. Also, instead of the peripheral wall being made up of the narrow short side panels 1 and the wide long side panels 2, the peripheral wall may be made up of four side panels of the same width.

The present invention can be carried out as described above.
That is, as shown in FIGS.
A packaging box 50 having four side panels (short side panel 1, long side panel 2) arranged alternately to form a peripheral wall, and flaps 4, 5 connected to each side panel are closed to form a box shape,
At least one side panel has
a zipper line 14 extending obliquely downward from the position of a handle portion 19 disposed at the upper end of the left-right center of the side panel toward a fold 8 extending in the up-down direction at the left and right edges of the side panel, and extending downward along the fold 8 after reaching the fold 8;
The packaging box 50 has a side flap 16 which is opened by pulling up a handle 19 and breaking a zipper line 14.

This configuration allows the side flap 16 to be pulled up to open the packaging box 50, reducing the burden on the worker who opens the box.

Also, as shown in FIG. 3, the inclined line portion 14a of the zipper line 14, which extends diagonally upward from the center of the left and right sides of the side panel, is positioned at a position shifted upward from the center in the vertical direction of the side panel.

This configuration allows a wide opening 52 to be formed after the side flap 16 is opened, making it easy to remove bottle containers and other items stored in the packaging box.

Also, as shown in FIG. 3, the inclined line portion 14a of the zipper line 14 near the fold 8 is made up of a small through line 15b that is shorter in length than other portions.

This configuration maintains the continuity of the zipper line 14 and ensures ease of opening. It also maintains the strength of the surrounding areas, and suppresses so-called bulging (lateral deformation caused by the packaging box being crushed) during stacking (when the packaging boxes are stacked). The length and arrangement of the small through lines 15b are not particularly limited, but for example, as shown in the example of Figure 3, a configuration can be adopted in which two straight lines each about 1/4 the length of the other through lines 15a are arranged.

Also, as shown in Figures 3 and 4 (B), a corner portion 18 is formed in the side panel (short side panel 1) in the area opposite the side flap 16 across the inclined line portion 14a, and the corner portion 18 remains when the side flap 16 is open.

With this configuration, the corner portion 18 functions as a so-called reinforcing portion, ensuring the rigidity of the packaging box 50 after opening.

As shown in Figs. 4(A) and 4(B), the side panels are made up of narrow short side panels 1 and wide long side panels 2 that are alternately connected to form a peripheral wall.
A zipper line 14 and a side flap 16 are formed on the narrow short side panel 1,
With the packaging box 50 in a vertical position with the short side panel 1 positioned on the top surface, the side flap 16 is pulled up to form an opening 52,
The packaging box is configured so that the contents (bottle container 40) can be removed from the top.

With this configuration, for example, when inserting a bottle container 40 into a vending machine, it is possible to hold the packaging box 50 in the left arm, open the side flap 16 with the right hand, and then insert the bottle container 40 with the right hand, thereby shortening the work time and improving efficiency.

As shown in FIG. 5, the packaging box 50 may be placed horizontally with the side flaps 16 open, allowing the bottle container to be removed horizontally. In this case, the corners 18 provide a wide opening while ensuring high rigidity, making it easy to remove the bottle container.
