Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging case in which a plurality of cans such as beverage cans are put together during transportation.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 6 to 7, six cans are put together in a packaging case, but FIG. 7 shows the development of this packaging case. As is apparent from this development view, there is an upper surface portion 22 at the center of the paperboard, and a pair of side surface portions 23 and 24 are continuous on both the left and right sides, and a bottom surface portion 25 is provided on both sides of the side surface portions 23 and 24. 26 in succession. A pair of pushing pieces 27 are formed on the upper surface portion 22. These push-in pieces 27 form a fold line 28 on the inside they face each other. Then, by bending the pushing piece 27 from the folding curve 28,
As shown in FIG. 6, a hole having a size such that a person's thumb can be inserted is formed in the pushed-in pushing piece portion.

A folding curve 29 is formed at the boundary between the upper surface portion 22 and the side surface portion 23, and the projecting piece 3 is located on the folding curve 29 and toward the outer side surface portion 23.
0, 31, 32 are formed. When the folding curve 29 is bent at a right angle, these protrusions become horizontal as shown in FIG. 6, and can upper fixing holes 33, 34, and 35 at which the corners of the can project are formed at the corners. ing. Further, the same bending line 36 and the protruding pieces 37, 38, 39 are formed on the boundary of the side surface portion 24 on the side opposite to the side surface portion 23.

[0004] The side surface portion 23, the protruding pieces 30, 3
The punching holes 40, 41, 4 are provided at positions facing 1, 32.
2 is formed and the punched holes 40, 41, 4
The tongue pieces 43, 44, and 45 are left on the inner side of 2. A folding curve 46 is formed between these punched holes and on the outermost side thereof. Further, the punching holes 47, 48, 49, the tongue piece 50,
51 and 52 and a bent line 53 are formed. And
By folding the above-mentioned folding lines 46 and 53, as shown in FIG.
At its bottom corner, as shown in FIG.
45, 50, 51, and 52 are projected, and the corresponding punched holes are located at the bottom corners thereof. Reference numeral 54 in the figure denotes a cut-off tape portion formed on the side surface portion 24.

On the outside of the side surface portion 23, the bottom surface portion 26 is continuous, and a pair of pressing pieces 55 is formed on the bottom surface portion 26. The pressing piece 55 is tapered outward and has a right-angled notch 56 at its tip. And this holding piece 55
The hole formed after the stand is raised is referred to as a hook hole 57. On the other hand, in the bottom surface portion 25 that is continuous with the side surface portion 24,
A pair of insertion holes 58 are formed. An arcuate notch 59 is formed further inside the insertion hole 58, and a portion surrounded by the notch serves as a hooking piece 60.

The packaging of the can with the paperboard punched out as described above will be described below. Six cans are arranged in two rows on the upper surface portion 22 at the center of the paperboard and placed upside down.
And, as if the folding curves 29 and 36 were to go along with the standing can,
Bend 90 degrees and fit the rim of the can into the can upper fixing holes 33, 34 and 35. Further, the folding curves 46 and 53 are put along the bottom of the can and bent at 90 degrees. Then, the punching holes 40, 41, 42, 47, 4 and
Fit on 8 and 49. Next, the bottom surface portion 25 is placed on the bottom surface portion 26. Then, the pressing piece 55 is raised, and the pressing piece 55 is made to dive into the insertion hole 58. After this, the tip of the hooking hole 57 is hooked on the hooking piece 60. In the can thus packaged, the cutting tape portion 54 is cut off to release the packaging state.

[0007]

In the conventional packaging case as described above, when the can is packaged, the pressing piece 55 is made to stand up and it is further submerged in the insertion hole 58, and the hooking hole 57 is provided. There is a problem in that the packaging process is complicated such that the hooks have to be hooked on the hooking pieces 60. Further, the cut-off tape portion is cut off to unwrap the rectangular tubular package. Therefore, the strip-shaped tape that has been cut off cannot be attached to the original position. Therefore, if the wrapping tape is opened with the cut tape, the wrapping case cannot be used again. It is an object of the present invention to provide a packaging case which is easy to assemble and which can be reused as long as the strength of the material allows.

[0008]

In order to achieve the above object, the packaging case for a can according to the present invention has at least 4 cans.
A bottom part that holds an area to hold more than one book, a pair of side faces that are continuous on both left and right sides of the bottom part through folding lines, and a pair of top faces that are continuous on each side part through folding lines Part, a fixing piece formed on at least one upper surface portion, and a fixing hole formed on at least the other upper surface portion, and these fixing piece and fixing hole are aligned when both upper surface portions are overlapped with each other. The feature is that a folding curve formed on one side of the fixing piece is bent and the bending curve is fitted into the fixing hole. The packaging case of the present invention may be made of paper or synthetic resin, and its material is not particularly limited. Further, it goes without saying that the number of cans that can be packaged may be any number as long as it is 4 or more.

[0009]

According to the present invention, a plurality of cans can be packaged by superposing one upper surface portion on the other upper surface portion and recessing the fixing piece. Further, after the packaging, the hole after the fixing piece is depressed serves as a handle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a development view showing a first embodiment. In this packaging case, a rectangular paperboard with rounded corners is punched out in a developed state as shown in the figure. That is, there is a bottom portion 1 at the center of the paperboard, and this bottom portion 1 holds an area capable of standing up to six target cans. However, the width x shown in FIG. 1 is made slightly smaller than the sum of the diameters of the two cans. Furthermore, as shown in FIG.
Side surface portions 4 and 5 are connected to the upper and lower sides of the bottom portion 1 via folding curves 2 and 3. The heights h of the side surface portions 4 and 5 are made to match the height of the can when the side surface portions 4 and 5 are bent from the folding curves 2 and 3 and are erected. Then, on each of the side surface portions 4 and 5, three cutout holes 6 are formed in parallel in the width direction orthogonal to the height direction h thereof. The cutout hole 6 thus formed is formed so as to fill the height direction h. The cut-out hole 6 has slanted portions 7 and 8 at its four corners to form a tapered shape as a whole, but the angle of the slanted portions 7 and 8 is adjusted to the vertical inclination of the target can. It was done like this.

Outside the side surface portions 4 and 5 as described above, the upper surface portions 11 and 12 are connected to each other through folding lines 9 and 10. A pair of fixing pieces 13, 13 are formed on the upper surface portions 11, 12. These pair of fixing pieces 1
3 and 13 are symmetric with each other, and a fold curve 14 is formed at their opposing portions. Further, the center of the fixing piece is separated from the folding curve 9 by a distance of about half the length x of the bottom surface portion 1.

Next, a packaging procedure using this packaging case will be described. First, six cans are arranged in two rows on the bottom part 1. Since the width x of the bottom portion is shorter than the total diameter of the two cans, when the cans are lined up on the bottom portion 1, the edges of the respective cans project slightly from the bottom portion 1. In this state, if the folding curves 2 and 3 on both sides of the bottom part 1 are bent,
Each can protrudes from the cutout hole 6, but in the end, the protrusion from the cutout hole 6 positions the can. Next, bend the folding curves 9 and 10,
The upper surface portions 11 and 12 are overlapped with each other, and the fixing piece 13 of the one upper surface portion 11 and the fixing piece 13 of the other upper surface portion 12 are aligned with each other. When the two fixing pieces 13 are aligned with each other in this manner, when the two fixing pieces 13 are pushed in and depressed, the fixing pieces 13 of the upper surface portion 12 located on the upper side are fixed to the fixing pieces of the upper surface portion 11 located on the lower side. Fits in 13 depressions.

When the upper fixing piece fits into the depression of the lower fixing piece in this manner, the upper surfaces 11 and 12 cannot be opened left and right, so that six cans are packed as shown in FIG. Will be done. In addition, in this embodiment, since the cutout holes 6 are formed in the side surface portions 4 and 5 so that the target can is projected from the cutout holes 6, when the upper surface portions 11 and 12 are pulled while being slightly tightly overlapped, Can maintain some elasticity. Therefore, if the fixing piece of the one upper surface portion 11 and the fixing piece of the other upper surface portion 12 are made to coincide with each other while maintaining this elasticity, one fixing piece fits into the depression hole of the other fixing piece. At this time, forces are exerted on the upper surface portions 11 and 12 so as to separate them from each other in the horizontal direction.

As described above, the more the force for separating them in the horizontal direction is exerted on both upper surface portions, the more the fixing piece 1 on one side.
It becomes difficult for 3 to come out from the recessed hole of the other fixing piece, and thus the packaging case maintains the packaging state firmly. For this reason, the upper surface portions 11 and 12 that are overlapped with each other are
Will not separate as long as the fixing piece 13 is folded inward. Then, unless the upper surface portions 11 and 12 are separated, the rectangular tube state of this package is maintained. As mentioned above, since the surface of the can projects from the cutout hole 6,
The pattern printed on the surface can be seen from outside the case. Therefore, the products can be identified without printing for a specific product in this case. for that reason,
The case can be used universally for various products.

FIG. 3 is an enlarged view of the fixing piece 13. The outer shape of the fixed piece 13 is formed by connecting a semi-circular arc portion 15 and a linear portion 16 continuing to both ends thereof. If the fixing piece is composed only of the semi-circular arc portion 15, when it is fitted into the recessed hole of the other fixing piece, the catching becomes worse. In other words, if only the semi-circular arc portion 15 is used, when a strong force is exerted on both upper surface portions 11 and 12 to separate them in the horizontal direction, the fixing piece fitted in the other recessed hole is likely to rise. Therefore, the force for stopping the superposition of the upper surface portions becomes small. Therefore, in this embodiment, in order to ensure the fixation of the upper surface portions 11 and 12, in addition to the semi-circular arc portion 15 which constitutes the fixing piece 13,
The straight part 16 is provided. As a result, when the fixing piece 13 is fitted into the depression hole of the other fixing piece, the straight portion 16 thereof comes into firm contact with the inner circumference of the depression hole, and the upper surface portion 1
It secures the fixation of 1 and 12. Further, even if the side surface portions 4 and 5 are pressed and the tension between the upper surface portions 11 and 12 is loosened, the fixing piece 13 is increased by the length of the linear portion 15, so that the upper surface portion 11 or 12 is Even if it rises to some extent, it will not come off.

FIG. 4 is a development view showing the second embodiment.
In the second embodiment, the fixing piece is removed from the other upper surface portion 12 to form the fixing hole 17, and the other points are the same as in the first embodiment. Therefore, in this second embodiment, the other upper surface portion 12 provided with the fixing holes 17 is always placed downward, and the one upper surface portion 11 is overlapped on the upper surface portion 12 to fix the fixing piece 1 of the upper surface portion 11.
3 is fitted in the fixing hole 17 of the upper surface portion 12.
Then, the fixing piece 13 is caught in the fixing hole 17 and can be fixed. Except for the above points, it is the same as the first embodiment, and therefore its details are omitted.

FIG. 5 is a sectional view showing the third embodiment.
In this third embodiment, two paperboards 18 are bonded with an adhesive 19 to form a three-layer structure. Therefore, the strength of paperboard is
Stronger than with a single board. Further in this example,
The smooth printed surface 20 is attached so as to be the front side. That is, the third embodiment assumes a case where the adhesive surface 21 is rough and unsuitable for printing. In such a case, by adhering the adhesive surfaces 21 to each other, it is possible to print both surfaces of the adhered three-layer board. Therefore, it is possible to print the front and back separately. Also, if the same printing is performed on both the front and back sides, the paperboard can be wrapped without distinguishing between the front and back sides.

[0018]

According to the packaging case for a can of the present invention, the packaging case can be assembled only by pushing the fixing piece, so that the packaging process is extremely simple compared with the conventional case.
Also, even when unpacking, it is easy to remove the fixing piece from the fixing hole, so it is easy, and even after removing it, if you put the fixing piece in the fixing hole, you can use the case many times be able to.
