Description

The present invention relates to a packaging box that is assembled from a corrugated cardboard plate and that houses and wraps containers such as canned beverages and bottled beverages.

Conventionally, after use, corrugated cardboard packaging boxes, especially those having a relatively large size, are generally folded into small pieces and discarded, and there are packaging boxes that facilitate this folding.

For example, in Patent Document 1, of the two sets of facing side plates constituting the body of the box, at least one set of facing side plates and the lid plate and / or bottom plate connected to the upper and lower sides thereof are repeatedly folded in a mountain fold and a valley fold. A packaging box having an accordion (bellows) structure provided with a wire so that the box after use can be easily and compactly folded is disclosed.

JP-A-2009-137625

However, the technique described in Patent Document 1 has a problem that the manufacturing process is complicated and the strength of the side surface is lowered because the facing side surface has a bellows structure.

In view of the above circumstances, an object of the present invention is to provide a packaging box that can be easily folded after use while maintaining strength.

In order to achieve the above object, the packaging box according to one embodiment of the present invention is connected to a top surface, a bottom surface, a pair of side surfaces connecting the top surface and the bottom surface, and each of the top surface, the bottom surface, and the side surface. It is a corrugated cardboard packaging box provided with a plurality of flaps. The top surface and the side surface, and the bottom surface and the side surface are connected to each other via a first bending line, and the top surface, the bottom surface and the side surface, and each of the flap portions are perpendicular to the first bending line, respectively. It is connected continuously via the second bending line. A plurality of holes are formed on the first bending line and on the line intersecting the first bending line, which straddles the top surface, the side surface, and the bottom surface.

With this configuration, by providing a hole on the first bending line, it is possible to provide a packaging box that can be easily folded after use while maintaining strength.

The hole may be formed on a line parallel to the second bending line.

As a result, the used packaging box can be neatly folded along the second bending line.

A third bending line may be formed on a line parallel to the second bending line.

As a result, the packaging box can be more easily folded by forming not only the holes but also the bending lines.

The third bending line may be a ruled line.

The ruled line may be an aggregate of a plurality of ruled lines (slash-shaped ruled lines) formed at predetermined intervals in a predetermined diagonal direction with respect to a line parallel to the second folding line.

As a result, compared to general straight ruled lines and perforations, the folds are less affected by the peaks and valleys of the steps when folded, and the folds are soft and wide, so the packaging box can be folded more easily. be able to.

The third bending line may be formed along the valley line of the corrugated cardboard step.

As a result, a crease is formed along the valley line, so that the packaging box can be folded more easily.

The hole may be formed in a diamond shape having vertices on a line parallel to the second bending line and on the first bending line.

As a result, since the apex of the rhombus is located on the line parallel to the second bending line, the packaging box can be easily folded from the apex.

The packaging box according to another embodiment of the present invention includes a top surface, a bottom surface, a pair of side surfaces connecting the top surface and the bottom surface, and a plurality of flaps connected to the top surface, the bottom surface, and the side surface, respectively. It is a corrugated cardboard packaging box provided with. The top surface and the side surface, and the bottom surface and the side surface are connected to each other via a first bending line, and the top surface, the bottom surface and the side surface, and each of the flap portions are perpendicular to the first bending line, respectively. It is connected continuously via the second bending line. A third bending line parallel to the second bending line is formed along the valley line of the corrugated cardboard step across the top surface, the side surface, and the bottom surface.

With this configuration, since folds are formed along the third folding line and the valley line, it is possible to provide a packaging box that can be easily folded after use while maintaining strength.

[Structure of packaging box and holes]
FIG. 1 is a perspective view showing the appearance of a packaging box according to an embodiment of the present invention. Further, FIG. 2 is a development view (blank view before assembly) of the packaging box.

As shown in both figures, the packaging box 100 is assembled from a corrugated cardboard plate, and has a top surface 1, a bottom surface 2, a pair of side surfaces 3 (3a, 3b), and a top surface 1, a bottom surface 2, and a side surface 3 thereof. Has a flap 4 connected to. The packaging box 100 contains an container such as a beverage can.

As shown in FIG. 2, a glue margin portion 6 extends on the long side of the side surface 3a, and the glue margin portion 6 is adhered to the end portion of the top surface 1 at the time of assembly.

The top surface 1 and the side surface 3 and the bottom surface 2 and the side surface 3 are connected to each other via the first bending line L1 (L1a, L1b, L1c, L1d from the left side of FIG. 2), respectively. The top surface 1, the bottom surface 2, the side surface 3, and each flap 4 are connected to each other via a second bending line L2 perpendicular to the first bending line.

On a line that bisects the first fold line L1 (a line parallel to the second fold line L2) or a line that bisects the top surface 1, the side surface 3, and the bottom surface 2, the third fold line is formed. It is preferable that the line L3 is formed. The third folding line L3 is an aggregate of a plurality of ruled lines (slash-shaped ruled lines) formed at predetermined intervals in a predetermined diagonal direction (for example, 45 degrees) with respect to a line parallel to the second folding line L2. More preferably.

The circular portion indicated by reference numeral S in FIG. 2 indicates the step of the corrugated cardboard plate constituting the packaging box 100. Mountain lines P and valley lines T appear alternately as the step S. The second bending line L2 and the third bending line L3 are formed in parallel with the step S. The third bending line L3 is preferably formed along the valley line T of the step S. That is, the third bending line L3 coincides with the valley line T as a line parallel to the second bending line L2, and each of the diagonal ruled lines is located between the two mountain lines P at both ends of the valley line T. It is possible to be provided as such.

Then, a plurality of hole portions 5 are formed at the intersection of the first bending line L1 and the third bending line L3. In the present embodiment, the hole 5 is formed on the second and fourth first bending lines L1b and L1d of the four first bending lines L1a, L1b, L1c, and L1d when viewed from the left side of FIG. 2, respectively. It is provided one by one.

The hole 5 is preferably formed in a diamond shape (square shape). As a result, the hole 5 can have upper and lower vertices on the first bending line L1 and left and right vertices on a line parallel to or parallel to the second bending line L2. The length of each side of the hole 5 is, for example, 10 mm, but the length is not limited to this, and is appropriately adjusted according to the size of the packaging box 100 and the like.

The hole 5 and the third folding line L3 are for facilitating folding when the packaging box 100 is disposed of after use.

[How to fold the packaging box]
Next, a method of folding the packaging box 100 at the time of disposal after use will be described.

The operator first opens all the flaps 4 of the packaging box 100 as shown in FIG.

Subsequently, as shown in FIG. 4, from the state of FIG. 3, the holes 5 are folded along the two first bending lines L1b and L1d formed to form a flat shape. As a result, the two holes 5 are located on both ends of the flat body.

Then, as shown in FIGS. 5 and 6, the flat packaging box 100 of FIG. 4 is folded in half (toward) with reference to the two holes 5 and the third bending line L3.

In this way, by using the hole 5 and the third folding line L3, the used packaging box 100 can be neatly folded along the second folding line L2.

Further, by making the shape of the hole 5 a rhombus, the apex of the rhombus is located on a line parallel to or parallel to the second bending line L2, so that the packaging box 100 can be easily folded from the apex. be able to.

Further, by making the third folding line L3 a slash-shaped ruled line, the third folding line L3 is formed as an aggregate of ruled lines having a predetermined width dimension in the vertical direction. As a result, the third bending line L3 is less affected by the peaks and valleys of the step S when folded, and becomes a soft and wide crease as compared with a general straight ruled line or perforation. The packaging box 100 can be folded more easily.

[Modification example]
The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.

In the above-described embodiment, the hole 5 is formed in a rhombus shape, but the hole 5 can be formed in any shape such as a rectangle or a circle other than the rhombus.

In the above-described embodiment, a diagonal (slash-shaped) ruled line is shown as the third folding line L3, but the third folding line L3 may be a general straight ruled line or a perforation (lead). It may be a ruled line) processed.

In the above-described embodiment, the hole 5 is formed on the second and fourth first bending lines L1b and L1d when viewed from the left side of FIG. 2 among the four first bending lines L1a, L1b, L1c, and L1d. A total of two were provided. However, the number and position of the holes 5 are not limited to this, and may be provided on all four first bending lines L1, for example. As a result, the distance between the holes 5 in the left-right direction can be narrowed, and the packaging box 100 can be easily folded starting from the apex of the holes 5.

Further, in the above-described embodiment, only one third bending line L3 is provided, but a plurality of third bending lines L3 may be provided. For example, two third fold lines L3 are formed so as to divide the first fold line L1 into three equal parts, and each of the two third fold lines L3 (that is, two for each first fold line L1). The hole 5 may be provided. As a result, the packaging box 100 has a plurality of third folding lines L3 in the vertical direction, and can be compactly folded.

In the above embodiment, the third bending line L3 is formed parallel to or parallel to the second bending line L2 (perpendicular to or perpendicular to the first bending line L1). However, if the third bending line L3 intersects the first bending line L1 over the top surface 1, the side surface 3, and the bottom surface 2, it is not necessarily parallel to the second bending line L2 (to the first bending line L1). It does not have to be vertical). For example, the third bending line L3 may be formed so that the angle with the second bending line L2 is 10 degrees or 20 degrees, and the hole portion 5 may be formed on the third bending line L3.

In the above-described embodiment, the hole 5 is provided on the third bending line L3. However, as a means for folding the used packaging box 100, the hole 5 may not be provided and only the third folding line L3 may be provided. In this case, the third folding line L3 is formed along the valley line T of the corrugated cardboard step S and parallel to the second folding line L2. As a result, even if the hole 5 is not provided, the packaging box 100 can be sufficiently functioned as a means for folding the packaging box 100.

In this case, the third fold line L3 is formed so that the line parallel to the second fold line L2 coincides with the valley line T, and the third fold line L3 is an oblique ruled line as in the above-described embodiment. For example, each of the diagonal ruled lines is provided so as to be located between two mountain lines P at both ends of the valley line T. When the third bending line L3 is parallel to or parallel to the second bending line L2, they are formed so as to coincide with the valley line T of the step S.
