Side plates 3 and 4 corresponding to the height of the can beer are connected to both sides of the top plate 2 via folding lines 2a and 2b that form boundaries.
[0023]
The bottom plates 5 and 6 are respectively formed with a female locking portion 7 (bottom plate 5 side) and a male locking portion 8 (bottom plate 6 side) that can be engaged with each other at the tip.
[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 developing sheet forming the leading end portion, and a vertical side 1a on the inner side. And a second locking portion 7b provided in parallel with each other. These 1st latching | locking part 7a and 2nd latching | locking part 7b are each provided in the center of the vertical side 1a, and the three places of the both ends side.
[0025]
In this embodiment, the shape of the first locking portion 7a is a 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 cut. It has become.
[0026]
On the other hand, the male locking portion 8 on the bottom plate 6 side located on the right side of the drawing is formed so as to be engaged 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 configured.
[0027]
In this embodiment, the shape of the first locking portion 8a is a straight line parallel to the vertical side 1a, and the center is a notch that forms a recess b on the 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 following tip is formed as a head portion c wider than the neck portion d. ing.
[0028]
Further, the side plates 3 and 4 are folded inward at the respective ends on the side 1b side to prevent the beer can from falling off between the top plate 2 and the corners of the bottom plates 5 and 6. Folding pieces 9 constituting the gussets 10a and 10b are connected in series via folding lines 3b and 4b that form boundaries. The state of the gussets 10a and 10b is shown in an easy-to-understand manner in FIG. Cuts may be made in the folds 3b and 4b of the folding piece 9 in order to facilitate folding inside.
[0029]
By attaching the bottom plates 5 and 6, the multipack packaging box 1 that can be stored so as to wrap a group of containers 19 such as canned beer is assembled. Then, as shown in FIG. 2, an opening P through which a part of the side surface of the container group is viewed is formed at both ends where the side plates 3 and 4 of the multipack packaging box 1 are not present.
[0030]
In the upper surface plate 2 of the present invention, a notch 50 is formed on the opening P side so that a part of the ring-shaped protrusion 95 formed on the peripheral edge of the top cover 90 of the container can be seen (see FIG. 1, see FIG.
[0031]
As shown in FIG. 3, such a cutout portion 50 includes cutout start base points 51 a and 51 b (represented by the cutout portion located at the upper right side of the four cutout portions as a representative). It is desirable to set the notch maximum depth length G to be at least 3 mm or more (particularly, 3 to 30 mm), more preferably 8 to 12 mm, with respect to the straight line L connecting each other. This is so that the can product can be pulled out as easily and easily as possible (improvement of ease of removal).
[0032]
The length L of the straight line connecting the notch start base points 51a and 51b is set to a dimension equal to or smaller than the width of one container. More specifically, it is desirable to set in the range of 6 to 60 mm, preferably 16 to 24 mm. This is for ensuring sufficient space for pulling out the can product and improving the ease of removal.
[0033]
In addition, when the notch maximum depth length G exceeds 30 mm, for example, an unexpected 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 notch start base points 51a and 51b exceeds 60 mm, inconveniences such as dropping of the can may occur.
[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 straight line length L and the notch maximum depth length G were set using a take-out device in which a load cell was connected to a jig shown in FIG. That is, the hook force at the tip of the jig is hooked on the ring-shaped protrusion 95 of the top lid 90 of the container to measure the take-out force when taking out one can (considering holdability in the container to some extent), and the above optimum value 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 locations), 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 places), reference numeral 15b denotes a bottom gusset hole (four places), reference numeral 16 denotes finger holes (two places), reference numeral 17 denotes a cut 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 the bottom of six can beers facing upward are placed in parallel in two rows on the upper portion of the top plate 2.
[0038]
Then, the side plates 3 and 4 are folded inward with the fold lines 2a and 2b as boundary lines so as to cover the side portions of the canned beer, and the bottom plates 5 and 6 are folded along the fold line 3a so as to cover the bottom portion of the canned beer. , 4a are folded inward, and the male second locking portion 8b provided on the vertical side 1a of the bottom plate 6 is provided in the direction of the vertical side 1a on the bottom plate 5 side from the head c. The first locking portion 7a on the female side is engaged with the second locking portion 7b through the hole of the first locking portion 7a to prevent the neck portion d of the first locking portion 8a from coming off and the concave portion of the first locking portion 8a on the male side. The pack sheet 1 is formed in an endless state by engaging b with one side a forming a horizontally long square hole of the first locking portion 7a on the female side. It becomes a packaging box for packs.
[0039]
At this time, when each folded piece 9 is folded inward, the top gusset 10a is formed at the corners of the top plate 2 and the side plates 3 and 4, and the side plates 3 and 4 are bottomed at the corners of the bottom plates 5 and 6. Each of the gussets 10b is formed, and canned beer packaged in the multipack packaging box 1 is prevented from coming off.
[0040]
When the pack sheet 1 is turned over so that the surface of the upper surface plate 2 faces up, 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 peripheral edge of the top cover 90 of canned beer is an opening P of the top plate 2. It peeks at the location of the notch 50 formed on the side. In the present invention, since the design of the notch 50 is set to the optimum condition, canned beer can be easily taken out by hooking and pulling a part of the ring-shaped protrusion 95 that is peeping on the tip of the finger. .
[0041]
FIG. 4 is a perspective view of a carton case 20 in which canned multipack packaging box 1 as shown in FIG. 2 is housed. In this, four canned multipack packaging boxes are arranged in series and in parallel. It is the size that can be stored. When storing the four can-packed multipack packaging boxes, 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 (second embodiment) of another specific embodiment of the multipack 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 the development view of the multipack packaging box of the present invention. In the second embodiment, the forms other than the upper surface plate 2 'are the same as the developed view (FIG. 1) of the first embodiment described above.
[0044]
The second embodiment is different from the first embodiment described above in the basic form of a notch 50 formed on the opening P side of the top plate 2 ′ as shown in FIG. That is, the cutout portions 50 in the second embodiment are not provided in the same number as the number of containers viewed from the opening P, but each top surface for all of the container groups viewed from the opening P. It is in the point which is notched and formed so that a part of lid may look. “Integrally formed with cutouts” refers to cutouts formed as a single cutout combined in form.
[0045]
In FIG. 6, the length L of the straight line connecting the notch start base points 52a and 52b is within the range of the total width of the container group viewed from the opening P (if two cans are arranged as shown in FIG. It is set to a length that allows a part of each top cover to be viewed through all the container groups viewed from the opening P. Furthermore, it is desirable to set the maximum depth G of the notch to be 3 mm or more (3 to 30 mm), particularly 8 to 12 mm. The straight line length L and the cutout maximum depth length G were set by using a take-out device in which a load cell was connected to the jig shown in FIG. 5 as described above.
[0046]
In addition, although embodiment of this invention demonstrated taking the packaging of beer cans as an example, it is not limited to this. For example, it can of course be applied to juice cans and other various can products.
