  By the way, as shown in FIG. 7, the multipack package M in which the cans C are packaged is packed in a cardboard box B in a wrap round format and delivered. When the cardboard boxes B are stacked, as shown in FIG. 8 (a), the cardboard boxes B to be placed are hit against the upper ridges of the cardboard boxes B that have already been stacked, as shown in FIG. 8 (b). In addition, it may collide with the upper ridge of the lower cardboard box B.

In such a case, a very large impact is locally applied to the multi-pack package M accommodated in the cardboard box B, and the holes 59 are formed in the ridges of the bottom plate 53 as shown in FIG. In some cases, a tear t ₁ may be generated from both end edges, and a tear t ₂ may be generated at a connecting portion between the side plate 52 and the folded piece 56 as shown in FIG. 9B. And when such a tear arises, there exists a possibility that the can C may not be hold | maintained by the multipack package M. FIG.

  Therefore, the present invention has an object to provide a multi-pack package that is unlikely to be broken so that the holding force of a can is impaired even if a large impact is applied in a state of being packed in a cardboard box in a distribution process. To do.

In order to solve the above-mentioned problem, the present invention is such that side plates and bottom plates are sequentially arranged on both sides of the top plate, folding pieces are extended from both ends of the side plate near the top plate, and the folding pieces and the corner portions of the top plate are provided. Connected by holding pieces, a fixed piece by cutting is formed from the bottom plate on both sides to the lower part of the side plate, and a crease line extending in the width direction is put in the base part and the intermediate part of the fixed piece, respectively.
A plurality of accumulated cans are surrounded by the top plate and side plates and bottom plates on both sides, and the bottom plates on both sides are connected and held in a sleeve shape,
The folded piece is folded inward, the holding piece is held at the upper part of the can along the upper outer periphery of the can, and the fixed piece is folded in the opposite direction around the fold line of the base and the middle part and fixed. In the multi-pack package in which the tip of the piece is engaged with the peripheral edge of the recess on the bottom of the can and the lower part of the can is held, thereby preventing the can from coming off from the opening on both ends.
A perforation in which the cut and the connecting portion are intermittently extended so as to extend in the direction connecting the openings of both end faces to the central portion of the boundary between the top plate and the side plate or in the vicinity thereof, and so as not to reach any end edge. It was assumed that a weak line of the shape was put.

  In the multi-pack package according to the present invention, even when a large impact is applied during the handling operation in a state of being packed in a cardboard box, the central portion of the boundary between the top plate and the side plate or the side plate which does not significantly affect the holding of the can Since the joint between the cuts breaks at the weak line put in the vicinity, the impact is absorbed, so that it is difficult to cause a tear that impairs the holding power of the can.

  First, a first embodiment of the present invention will be described with reference to FIGS.

  The multi-pack package shown in FIG. 1 wraps three cans C in two rows so that six cans C containing beer can be carried together, and is water resistant as shown in FIG. It is formed from a paperboard blank.

  In this blank, the side plate 2 and the bottom plate 3 are successively arranged on both sides of the top plate 1, the insertion piece 4 and the engagement piece 4 a on one bottom plate 3, and the insertion hole 5 and the engagement on the other bottom plate 3. Each hole 5a is provided. The insertion hole 5 has a slit shape, and a pressing piece 5b is formed by cutting into the insertion hole 5.

  Folding pieces 6 are connected to both side edges of the side plate 2 near the top plate 1, and the folding pieces 6 and the corners of the top plate 1 are connected by holding pieces 7.

  From the bottom plate 3 to the lower portion of the side plate 2, three fixed pieces 8 having rounded tips are formed by cutting, and a crease line 8 a extending in the width direction is formed at the base portion and the intermediate portion of the fixed piece 8. , 8b are respectively inserted. The fixing piece 8 is raised along with the folding along the crease lines 8a and 8b at the time of packaging, and a hole 9 is formed in the extraction trace.

  The top plate 1 is formed with a finger pressing piece 10 that forms a finger insertion hole for transportation, and is cut at the time of opening to take out the can C, so that it can be taken from one edge to the other edge. In addition, two zipper-type cut lines 11 in which the bowl-shaped cuts are intermittent are provided.

  In the center of the boundary between the top plate 1 and the side plates 2 on both sides, a perforated weakening line 12 is formed on the border line of the boundary. The weakening line 12 does not reach any end edge of the boundary between the top plate 1 and the side plate 2.

  In order to assemble and wrap the can C as shown in FIG. 1 by assembling the blank as described above, the top plate 1 is put on the upper surface of the accumulated can C, the side plates 2 on both sides are bent downward, and the bottom plate 3 is Bend inward. And the engagement piece 4a and the engagement hole 5a of the bottom plate 3 are engaged, the insertion piece 4 is inserted into the insertion hole 5, the bottom plates 3 are connected to each other, and the shape is maintained in a sleeve shape.

  Further, the folding piece 6 is folded inward, the holding piece 7 is placed along the outer periphery of the upper portion of the can C, the upper portion of the can C is held, and the fixed piece 8 is folded in opposite directions around the crease lines 8a and 8b. The tip of the fixed piece 8 is engaged with the peripheral edge of the concave portion of the bottom surface of the can C, and the outer periphery of the bottom of the can C is fitted into the punched hole 9 formed in the boundary portion between the side plate 2 and the bottom plate 3. Is held to prevent the can C from coming off from the openings on both end faces.

  As shown in FIG. 7, the multipack package in which the cans C are packaged in this way is packed in a cardboard box of a wrap round type as shown in FIG.

  At this time, as shown in FIGS. 8A and 8B, even if the cardboard boxes B are roughly handled at the time of stacking and a very large impact is applied locally to the multipack package M, As shown in FIG. 3, in the said multipack package, the connection part 12b between the notches 12a is formed by the weakening line 12 which is put in the center part of the boundary between the top plate 1 and the side plate 2 which does not affect the holding of the can C so much. Since the impact is absorbed by the fracture, the tear is unlikely to occur so that the holding force of the can C is impaired.

  Next, a second embodiment of the present invention will be described with reference to FIGS. Since the second embodiment has the same basic configuration as that of the first embodiment, the description regarding the common parts is omitted here, and only the differences are mentioned.

  This multi-pack package is assembled from the blank shown in FIG. 5, and a hole 9 a larger than the hole 9 of the first embodiment is formed at the boundary between the side plate 2 and the bottom plate 3. A hole 9b is formed at the boundary with the top plate 1. The length of the top plate 1, the side plates 2 on both sides, and the bottom plate 3 in the connecting direction is slightly shorter than that of the first embodiment.

  At the boundary between the top plate 1 and the side plates 2 on both sides, a perforated weakening line 12 is formed on the border line of the boundary from the vicinity of the central hole 9b toward both ends. . The end of the hole 9b of the weakening line 12 is provided with a notch 9c for preventing breakage, and the same notch is formed at the other end of the ruled line at the boundary between the side plate 2, the top plate 1 and the bottom plate 3. Is also included.

  In the packaging state of the can C shown in FIG. 4, the can C is strongly tightened by the top plate 1, the side plates 2 and the bottom plate 3 formed in a sleeve shape, and the bottom outer periphery and the top of the can C are removed from the punched holes 9a and 9b. The outer periphery protrudes from each other.

  Even in such a multi-pack package, in the distribution process, when it is roughly piled up in a state of being packed in a cardboard box and a very large impact is applied locally, a central portion of the boundary between the top plate 1 and the side plate 2 is applied. Since the impact is absorbed when the connecting portion 12b between the cuts 12a is broken by the weakened line 12 that has been put in, the can C can be broken like a tear from the vicinity of the end of the punched hole 9b to the cut line 11 for opening. It is difficult for tears to lose its holding power.

  In each of the above embodiments, if the length of the weakening line 12 is set to be too long with respect to the length of the boundary between the top plate 1 and the side plate 2, the packaging strength during carrying alone will be reduced. The ratio of the length of the line 12 is preferably about 1/5 to 1/2.

  Moreover, in the said embodiment, although the cut line 12a was illustrated as the weakening line 12 with a fixed pitch, it is good also as what the pitch of the cut 12a changes.

  Further, although the weak line 12 is illustrated as a straight line extending on the boundary between the top plate 1 and the side plate 2, the weak line 12 may be placed at a position slightly shifted from the boundary between the top plate 1 and the side plate 2. They may be curved or zigzag wavy.
