[Prior art]
[Patent Document 1] Japanese Patent Application Laid-Open No. 2001-233378 Conventionally, a plurality of containers such as canned beer and canned juice are arranged and arranged in a state of being erected in a single row or a plurality of rows, and then the upper part of the container A multi-pack packaging box made of paper, which is wrapped so as to enclose the side and the lower part, is used.
[0003]
By using such a multi-pack packaging box, a plurality of canned beers, canned juices, and the like can be packaged in one package and easily carried at once, and furthermore, the effect of collective selling can be obtained. In addition, the use of the multi-pack packaging box has been rapidly expanding in recent years.
[0004]
For example, when a beer or the like stored in such a multi-pack packaging box is to be delivered from a wholesaler to a retail store or the like, the flap at the opening on the front side is usually opened in one shipping carton case. Four multi-pack packaging boxes are stored in two rows and two rows through the opening and are carried out.
[0005]
[Problems to be solved by the invention]
Therefore, in a retail store or the like, it is necessary to individually pull out the multi-pack packaging boxes stored in the shipping carton case. The extracted multi-pack packaging box is then (1) taken out of the multi-pack packaging box from the multi-pack packaging box at a retail store and sold in bulk, or (2) eat and drink. At the same time, the can product is taken out of the multi-pack packaging box by the purchaser's hand.
[0006]
In addition, in recent years when consumers often purchase products in shipping carton cases, sometimes can products can be taken directly from a multi-pack packaging box left in a shipping carton case. It is said that operations such as taking out are also being performed.
[0007]
In any case, various methods can be adopted as a method for removing cans one by one from the current paper multi-pack packaging box. As one of them, insert a finger from one of the openings at both ends where the side plate of the multi-pack packaging box does not exist, and hook the finger tip on the ring-shaped protrusion formed on the periphery of the top lid of the can product. A method of forcibly extracting a can product may be performed. In such a case, the packaging box carton may pierce between the nails and injure the fingertip. In addition, it is desirable that the extraction of can products be performed as easily and smoothly as possible (improvement in ease of removal).
[0008]
The present invention has been devised in view of such circumstances, and an object of the present invention is to solve the above-mentioned problems, to allow safer removal of can products from a multi-pack packaging box, and to facilitate removal. It is an object of the present invention to provide a multi-pack packaging box which can improve the performance (it does not easily pop out when it is in the multi-pack packaging box and can be relatively easily taken out when trying to take it out).
[0009]

It has an area consisting of two cans of beer. Side plates 3 and 4 corresponding to the height of the can beer are provided on both sides of the upper plate 2 via folding lines 2a and 2b, which are boundaries, respectively, so as to cover side portions of the canned beer.
[0023]
A female locking portion 7 (bottom plate 5 side) and a male locking portion 8 (bottom plate 6 side) are formed on the bottom plates 5 and 6, respectively.
[0024]
The locking portion 7 on the bottom plate 5 side located on the left side of the drawing includes a first locking portion 7a parallel to one vertical side 1a of the development sheet forming the front end portion, and a vertical side 1a inside the first locking portion 7a. And a second locking portion 7b provided in parallel to The first locking portion 7a and the second locking portion 7b are provided at the center of the vertical side 1a and at three places on both ends.
[0025]
In this embodiment, the shape of the first locking portion 7a is a cut out vertically elongated substantially square hole, one side a of the hole is formed in the engaging portion, and the shape of the second locking portion 7b is the notch. It has become.
[0026]
On the other hand, the male locking portion 8 on the bottom plate 6 located on the right side of the drawing is formed so as to be able to engage with the first locking portion 7a and the second locking portion 7b, respectively. The first locking portion 8a and the second locking portion 8b are provided.
[0027]
In this embodiment, the shape of the first locking portion 8a is a notch that is a straight line parallel to the vertical side 1a and whose center is a concave portion b inside. The shape of the second locking portion 8b is tapered from the width of the first locking portion 8a to the outside of the vertical side 1a to reach the neck portion d, and the tip following this is formed as a head c having a width larger than the neck portion d. ing.
[0028]
Further, each end of the side plates 3 and 4 on the side of the side 1b is folded inward to prevent the beer can from falling off between the upper plate 2 and the corners of the bottom plates 5 and 6. The fold pieces 9 constituting the gussets 10a and 10b are connected to each other via fold lines 3b and 4b forming borders. The state of the gussets 10a and 10b is shown in FIG. Cuts may be made in the folds 3b, 4b of the fold-in piece 9 to facilitate inward folding.
[0029]
By attaching the bottom plates 5 and 6 as described above, the multi-pack packaging box 1 that can be stored so as to wrap a group of containers 19 such as canned beer or the like is assembled. Then, as shown in FIG. 2, openings P are formed at both ends of the multi-pack packaging box 1 where the side plates 3 and 4 do not exist, respectively, so that some side surfaces of the container group can be seen.
[0030]
In the upper plate 2 of the present invention, a cutout portion 50 is formed on the opening P side so that a part of a ring-shaped protrusion 95 formed on the periphery of the top cover 90 of the container can be seen. 1, see FIG. 2).
[0031]
As shown in FIG. 3, such notches 50 are notch start base points 51a and 51b (a notch located at the upper right portion of the four notches is shown as a representative). It is desirable to set the notch maximum depth length G to be at least 3 mm or more (especially 3 to 30 mm), more preferably 8 to 12 mm, with respect to the straight line L connecting the two. This is to make it possible to pull out the can product as simply and easily as possible (improvement in ease of taking out).
[0032]
The length L of the straight line connecting the base points 51a and 51b at the start of the notch is set to be equal to or smaller than the width of one container. More specifically, it is desirable to set the range of 6 to 60 mm, preferably 16 to 24 mm. This is for the purpose of securing a sufficient space for pulling out the can product and improving the ease of taking out.
[0033]
If the maximum depth G of the notch exceeds 30 mm, for example, a sudden drop of the can caused by hooking the can product or a problem that the paperboard is sandwiched between the can lid and the tab may occur. Further, if the length L of the straight line connecting the base points 51a, 51b at the start of the notch exceeds 60 mm, there may be inconvenience such as dropping of the can.
[0034]
It is particularly preferable that the shape of the cutout portion 50 is a curved shape, and the number of the cutout portions 50 is desirably the same as the number of containers viewed from the opening P.
[0035]
The length L of the straight line and the maximum depth G of the notch were set using a take-out device in which a load cell was connected to a jig shown in FIG. That is, the hook at the tip of the jig is hooked on the ring-shaped projection 95 of the top cover 90 of the container, and the take-out force at the time of taking out one can is measured (considering the holdability in the container to some extent). It has been confirmed that a particularly remarkable effect (very remarkable ease of removal and safety) is exhibited within the above range.
[0036]
In FIG. 1, reference numeral 13 denotes a compression hole (six places), reference numeral 14a denotes a mountain fold line, and reference numeral 14b denotes a valley fold line. Further, reference numeral 15a denotes a top gusset hole (four locations), reference numeral 15b denotes a bottom gusset hole (four locations), reference numeral 16 denotes a finger hole (two locations), reference numeral 17 denotes a cutout line, and reference numeral 18 denotes a lot confirmation window. .
[0037]
Next, an example of a specific packaging operation will be described. First, the pack sheet shown in FIG. 1 is turned upside down, and three cans arranged in series with two bottoms of six canned beers facing upward are placed in two rows on the upper part of the upper surface plate 2.
[0038]
Then, the side plates 3 and 4 are folded inward with the fold lines 2a and 2b as border lines so as to cover the side portions of the can beer, and the bottom plates 5 and 6 are further folded along the fold line 3a so as to cover the bottom of the can beer. , 4a as a boundary line, and the male second locking portion 8b provided on the vertical side 1a of the bottom plate 6 is provided from the head c in the direction of the vertical side 1a on the bottom plate 5 side. The second locking portion 7b is engaged with the second locking portion 7b through the hole of the female first locking portion 7a to be locked at the neck d of the first locking portion 8a, and the concave portion of the male first locking portion 8a. b is engaged with one side a of the female first locking portion 7a forming a horizontally long rectangular hole, so that the pack sheet 1 is formed in an endless state, and the canned beer in a state in which the beer is covered with a band. It becomes a packing box for packs.
[0039]
At this time, when each folding piece 9 is folded inward, a top gusset 10a is provided at the corner between the top plate 2 and the side plates 3 and 4, and a bottom plate is provided at the corner between the side plates 3 and 4 and the bottom plates 5 and 6. The gussets 10b are respectively formed, and the canned beer packaged in the multi-pack packaging box 1 is prevented from falling off.
[0040]
When this pack sheet 1 is turned over so that the upper surface plate 2 faces upward, a form of a perspective view as shown in FIG. 2 is obtained. FIG. 3 is a plan view of FIG. 2, and as can be seen from these drawings, a part of the ring-shaped protrusion 95 formed on the periphery of the top lid 90 of the canned beer has an opening P of the top plate 2. It is looking at the notch 50 formed on the side. In the present invention, since the design of the cutout portion 50 is set to an optimum condition, a part of the ring-shaped protrusion 95 being looked at can be easily taken out by hooking the tip of the finger and pulling it. .
[0041]
FIG. 4 is a perspective view of a carton case 20 in which the multi-pack packaging box 1 with cans as shown in FIG. 2 is provided. In FIG. 4, four multi-pack packaging boxes with cans are arranged in series and in parallel. It is the size that can be stored. When storing four packaging boxes for a multi-pack containing cans, the upper and lower flaps 20a and 20b on the short side are opened as shown in FIG. 4, and then the flaps 20a and 20b are closed to complete the storage.
[0042]
Description of Second Embodiment Next, an example (a second embodiment) of another specific embodiment of the multi-pack packaging box 1 of the present invention will be described with reference to FIG.
[0043]
FIG. 6 shows an upper surface plate 2 '(second embodiment) as a main part in a development view of the multi-pack packaging box of the present invention. In the second embodiment, the configuration other than the upper surface plate 2 'is the same as the development view (FIG. 1) of the first embodiment described above.
[0044]
As shown in FIG. 6, the second embodiment differs from the first embodiment in a basic form of a notch 50 formed on the opening P side of the upper surface plate 2 '. That is, the notches 50 in the second embodiment are not provided in the same number as the number of containers peeping from the opening P, but are provided on all top surfaces of the container group peeping through the opening P. The point is that a part of the lid is cut out integrally so as to be seen. “Integrally formed notch” refers to a notch formed as one notch that is morphologically integrated.
[0045]
In FIG. 6, the length L of the straight line connecting the base points 52a and 52b at the start of the notch is within the range of the total width of the container group viewed from the opening P (two cans as shown in FIG. (Within the range of the width), and a length that allows a part of each top cover to be seen through the entire container group seen through the opening P. Furthermore, it is desirable that the notch maximum depth length G is set to be 3 mm or more (3 to 30 mm), particularly 8 to 12 mm. The setting of the length L of the straight line and the maximum depth G of the notch was performed using the take-out device in which the load cell was connected to the jig shown in FIG. 5 as described above.
[0046]
In the embodiment of the present invention, the packaging of beer cans has been described as an example, but the present invention is not limited to this. For example, it goes without saying that the present invention can be applied to juice cans and other various can products.
[0047]
