Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container for packaging articles such as cans and bottles, and more particularly to a portable handle on the top wall in the state where a cylindrical article such as a can is packaged. A packaging container suitable for forming.

[0002]

2. Description of the Related Art Articles such as cans filled with beer or juice are generally packed in one packaging container in a single stage by arranging, for example, 4 articles in 4 rows in 6 rows. It is like this.

Such a packaging container has a flat shape,
Since the vertical handle is stable to carry, the portable handle is formed on the side wall or the end wall of the packaging container where the side wall of the can opposes. When the handle is formed on the side wall or end wall of the packaging container where the side walls of the can face each other in this way, there is a relatively large gap between the side wall or end wall of the packaging container and the side wall of each can forming a cylindrical surface. And a pair of handle forming openings spaced apart from each other on the side wall or end wall of the packaging container with a separating piece that is at least partially separated from the side wall of the packaging container. It can be done easily.

[0004]

However, since the above-mentioned flat-shaped packaging container has a flat shape as a whole, the packaging containers each containing an article are stacked and sold in plural stages. In the case of, the area of the side wall or the end wall exposed to the outside corresponds to the projected area from the side orthogonal to the alignment direction of the articles when the six articles are aligned in the case of packaging 24 articles, Since the end wall corresponds to a similar projected area when four articles are aligned, the area of the side wall or the end wall exposed to the outside of this packaging container is small, and the side wall or the end wall is flat. There is a problem in that it is difficult for consumers to see the articles on the wall.

In view of such a point, in recent years, a packaging container has been developed in which the area of the side wall or the end wall exposed to the outside is larger than that of the conventional packaging container. In this improved packaging container, for example, in order to wrap 24 cans, 12 cans are arranged in 2 stages by arranging 3 cans in 1 line over 4 lines. Looking at the areas of the side wall and the end wall exposed to the outside in this improved packaging container, each of the two side walls facing each other in the packaging for 24 pieces has eight articles arranged in two stages of four pieces. It corresponds to the projected area from the side orthogonal to the alignment direction of the articles when they are made, and the two opposing end walls correspond to the same projected area when the articles are aligned in two stages of three articles each. Therefore, the area of the side wall or end wall exposed to the outside of this improved packaging container is larger than the area of the side wall or end wall of the conventional packaging container described above, and each has a shape close to a square, The display of the article on the side wall or the end wall is easily noticed by the consumer.

By the way, in the improved packaging container described above, a handle is formed on the top wall in order to carry it vertically because of its three-dimensional shape. Then, in order to form the handle, the top wall has a part as a cutting line and the rest as a folding line, or a separating piece which is at least partially separated from the top wall as a cutting line. The pair of grip forming openings are formed so as to be spaced from each other. Even if the separating pieces are all cut lines, they are connected to the top wall with a slight connecting portion until the handle is formed.

In the improved packaging container described above, the top wall of each packaged can faces the top wall on which the handle is formed, and a small gap is formed between adjacent cans. Therefore, even if each of the separating pieces is pushed in with a fingertip to form a handle, the separating pieces come into contact with the top wall of the can, and it is difficult to completely bend the separating pieces. As a result, the handle could not be formed unless the separating piece was bent forcibly.

In view of the above points, the present invention makes it easy to form a separating piece on the top wall even when packaging an article such as a can which has a cylindrical shape and a large gap cannot be formed up to the top between the adjacent pieces. An object of the present invention is to provide a packaging container in which a handle can be easily formed by pushing into a container.

[0009]

To achieve the above object, the packaging container of the present invention has a pair of handle forming openings in the top wall with a separating piece that is at least partially separated from the top wall. In a packaging container formed to be spaced apart from each other and containing a plurality of articles therein, the separation pieces for forming each of the openings are continuously provided to the top wall via a folding curve and the folding curve. And a second separating piece part that can be separated from the first separating piece part that can be fitted into the space between the adjacent articles by being bent inward along the It is characterized by that.

[0010]

According to the packaging container of the present invention described above, since the separating piece has the first separating piece portion, if the first separating piece portion is pushed with a finger, the first separating piece portion will be adjacent. Since it fits into the space between the articles, the second separating piece can be easily separated from the top wall through the opening of the first separating piece separated from the top wall, and the handle can be easily formed. be able to.

Further, the end walls 11 and 12 are formed on both sides of the first side wall 11 via folding lines 17 and 18, respectively.
Narrow auxiliary end walls 19 and 20 located inside are provided so as to project. Also, on both sides of the second side wall 12, the end walls 11 and 12 of the respective end walls 11 and 12 are respectively bent via folding lines 21 and 22. Narrow width auxiliary end walls 23 and 24 located inside are projected.

On the top wall 2, a pair of handle forming openings 26, 26 for forming a handle 25 on the top wall 2 are formed at intervals. Opening 26 for forming both handles
Are the upper end walls 11 at the center of the top wall 2, respectively.
The handle forming openings 26, 26 are elongated holes extending in the directions A, 11B, and the central portions of the strip-shaped handles 25 formed in the center of the top wall 2 in the longitudinal direction and the width direction. It is positioned so that it extends in parallel.

Each of the handle forming openings 26 is formed in the top wall 2.
Separation piece 2 having the same shape as the handle forming opening 26 connected to
Originally closed by 7. The separation piece 27
Is composed of a first separating piece portion 27A and a second separating piece portion 27B which are adjacent to each other and separated so as to be independently bendable. Of these, the first separating piece portion 27A faces the inside of the handle forming opening 26 from the central position in the longitudinal direction of the handle forming opening 26 so as to be adjacent to the handle 25 via a folding line 28. . The shape of the first separating piece portion 27A is the first when the blank 1 is assembled into a packaging container and the can is packaged inside.
A triangle is formed by a curved line so that when the separating piece portion 27A is bent through the folding line 28 and is pushed into the packaging container, it can be fitted into the space between the adjacent cans. It is shaped. The second separating piece portion 27B has a shape in which a concave portion corresponding to the shape of the first separating piece portion 27A is formed in the shape of the separating piece 27 corresponding to the shape of the handle forming opening 26. The second separating piece portion 27B is connected to the top wall 2 via a plurality of dot-like connecting portions (not shown). This second separating piece portion 27B
Is connected to the top wall 2 in this manner so that the second separating piece portion 27B can be separated from the top wall 2 and can be bent with respect to the top wall 2. is there.

Three auxiliary folding curves 29, 29 ... Which reach the corners of the top wall 2 from both ends of each handle forming opening 26 are formed. These three auxiliary folding curves 29 are formed so as to gradually expand from the end of each handle forming opening 26 to the corner of the top wall 2, and each corner of the top wall 2 is expanded. An inclined cutting line 30 connecting the tips of the three auxiliary folding curves 29 is formed on the. The auxiliary folding curve 29 and the cutting line 30 are for facilitating formation of a gap between the top wall 2 and the upper end of the can when the handle 25 is pulled up.

At one side edge of the upper end walls 11A and 12A, both end portions 31A of the handle reinforcing piece 31 having a substantially U shape,
31A is connected to each other via folding curves 32 and 33. The width of the intermediate portion 31B of the handle reinforcing piece 31 is equal to or slightly smaller than the width of the handle 25.
When bent 180 degrees along 33, this handle reinforcement piece 31
The intermediate portion 31B of the above is closely attached to the back surface of the handle 25. Therefore, by adhering the intermediate portion 31B of the handle reinforcing piece 31 to the back surface of the top wall 2, the handle reinforcing piece 31 is integrated with the back surface of the handle 25, and the strength of the handle 25 can be increased.

The blank 1 is provided with a tear line 34 for taking out an internal can when it is used as a packaging container. Further, a glue margin 35 for connecting the second side wall 5 to the top wall 2 at the time of forming the packaging container is formed on the open side edge of the top wall 2.

In order to form the packaging container 40 in which the can C is packaged inside the blank 1 shown in FIG. 1, each folding curve 6, 7 and 8 is bent so that the top wall 2 has a second shape. Side wall 5
After applying an adhesive to the glue allowance 35 for connecting
The top wall 2 and the second side wall 5 are connected to each other, and the blank 1 is formed into a tubular shape. In this state, a total of 24 cans C, each 3 4
It is placed on the bottom wall 4 of the blank 1 so as to be stacked in two rows. Next, each upper end wall 11A, 12A, each lower end wall 11B, 12B and each auxiliary end wall 19, 20,
23 and 24 are each a bending curve 9, 10, 17, 18, 21, 21
Bend along 2 and each auxiliary end wall 19, 20, 23, 24
An adhesive is applied to the end walls 11 and 12 to seal them.

In this way, the packaging container 40 in which 24 cans C are packaged in a completely sealed state is completed. In this state, each handle forming opening 26 is closed by a separating piece 27. This is to prevent dust or the like from entering the inside of the packaging container 40 through the handle forming opening 26 in the open state.

Next, the operation of forming the handle 25 on the packaging container 40 will be described.

The first separating piece portion 27A and the second separating piece portion 27B constituting the separating piece 27 in each handle forming opening 26 formed on the top wall 2 of the packaging container 40 are shown in FIG. As described above, most of the first separation piece portion 27A including the tip end portion has a substantially cylindrical shape (the radius L1 of the body portion) and faces the space between the four cans C arranged in a square shape. There is. Moreover, the can of beer or the like actually has a frustoconical shape whose upper end gradually decreases in radius upward, and the shape of the upper end of the can C is a double concentric circle shown by an imaginary line in FIG. As indicated by the inner line L2, when the first separating piece portion 27A is pushed into the packaging container 40 to open each handle forming opening 26, the first separating piece portion 27A becomes almost a bent piece 28. It will be bent along and will be inserted in the space between the four cans C. Therefore, by bending the first separating piece portion 27A by 180 degrees so that the handle 25 located between both the first separating piece portions 27A is floated upward, the first separating piece portion 27A is moved to the handle reinforcing piece 31. Can be adhered to.

Next, the second separating piece portion 27B left in each handle forming opening 26 is bent or cut to remove it from the inside of the handle forming opening 26. At this time, when the second separating piece portion 27B is to be bent inside the packaging container 40, the second separating piece portion 27B is left as it is.
Cannot be bent because it is caught in the can C, but after the first separating piece 27A is sufficiently bent, the handle 2
When 5 is picked up and lifted up, the top wall 2 is pulled along the three auxiliary folding curves 29 formed so as to extend in the four corner directions from the central portion of the top wall 2, Since the grip 25 is separated from the upper end of the internal can C so as to widen each cutting line 30 formed at each corner of the second separation piece 27B, the second separation piece 27B is bent inward. be able to.

As described above, according to this embodiment, the separation piece 27 that closes the handle forming opening 26 is the first separation piece part 2.
Since the first separating piece portion 27A has 7A, if the first separating piece portion 27A is pushed into the packaging container 40 with a finger, the first separating piece portion 27A will fit into the space between the adjacent cans C. Second through the opening of the first separating piece 27A separated from the wall 2
The separating piece portion 27B can be easily separated from the top wall 2, and as a result, the handle 25 can be easily formed.

The present invention is not limited to the above embodiment, but can be modified as necessary. For example, the articles packaged in the packaging container of the present invention are not limited to the cans described in the examples.

[0028]

As described above, according to the packaging container of the present invention, even if an article having a cylindrical shape such as a can and having no large void up to the top between adjacent articles is wrapped, It is possible to easily push the separation piece of the top wall to easily form the handle.
