FIG. 7 is a schematic perspective view schematically showing a state in which four multipack packaging boxes are stored in the shipping carton case 20. FIG. 8 is a plan view of the multipack packaging box as viewed from the top plate side.

  As a preferred embodiment of the present invention, a general multi-pack packaging box 1 capable of storing six cans of beer (three cans in series arranged in two rows) will be described as an example.

  The multipack packaging box 1 of the present invention can be formed by assembling the unfolding sheet (packing sheet) shown in FIG. 1, and the unfolding sheet has a horizontally long and substantially rectangular shape as shown in FIG. ing.

  In the unfolded sheet shown in FIG. 1, the central portion constitutes an upper surface plate 2, and side plates 3 and 4 are connected to both ends thereof. A bottom plate 5 is formed on the left side of the side plate 3 in the drawing, and a bottom plate 6 is formed on the right side of the side plate 4 in the drawing.

  The upper surface plate 2 covers the upper surface of six canned beers in which three in series are arranged upright in two parallel rows, so that three cans of beer cans in the direction of the vertical side 1a of the drawing, and in the direction of the horizontal pieces 1b It has an area consisting of the length of two beer cans. 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.

  The bottom plate 5 and the bottom plate 6 are respectively provided with a female locking window portion 7a (bottom plate 5 side) and a male locking portion 8a (bottom plate 6 side) that can be engaged with each other in the vicinity of the tip portion. Is formed. Locking window portions 7a on the bottom plate 5 side located on the left side of the drawing are respectively provided at the center and at three locations on both ends thereof along the vertical side 1a as shown. In this embodiment, the shape of the locking window portion 7a is a vertically elongated substantially rectangular hole cut out, and one side a of the hole is a substantial engaging portion. On the other hand, the shape of the locking portion 8a on the male side of the bottom plate 6 located on the right side of the drawing is a straight line parallel to the vertical side 1a and a notch with the center being a recess b on the inside.

  In addition to these engaging portions (locking portions), female side locking portions 7b and 7c are formed on the bottom plate 5 side located on the left side of the drawing. On the bottom plate 6 side, male engagement pieces 8b and 8c are formed, respectively. The shape of the female locking portions 7b and 7c located on the left side of the drawing is a cut. The shape of the male engagement piece 8c located on the right side of the drawing is squeezed so as to form a jaw portion from the hook-shaped head portion at the tip as shown in the drawing to the neck portion d. The other male engagement piece 8b (upper side in the figure) can also function as a locking portion, but is mainly assembled when assembling the stopper for preventing rolling of the container, which is a main part of the present invention. It functions as a hook piece 8b for shape fixing, which is one part of the member. Therefore, the hook piece 8b for form fixing has a hook plane part 81 that stands up from the bottom surface and exhibits a hook function, and a bent base part 85 when the hook plane part 81 is raised. An inclined side 86 extending from the end of the bent base 85 and a jaw 87 formed on the upper side of the inclined side 86 are formed. These specific functions will be described in detail later.

The state of the gussets 10a and 10b is shown in an easy-to-understand manner in FIG. 2, for example. It is desirable to make cuts (slits) in the folds 3b and 4b of the folding piece 9 in order to facilitate folding inside.

  By engaging the locking portions provided on the bottom plates 5 and 6 described above, the multipack packaging box 1 that can be stored so as to wrap a group of containers 19 such as canned beer is assembled. As shown in FIGS. 2 to 4, the first opening P <b> 1 through which a part of the side surface of the container group peeks at both ends where the side plates 3, 4 of the multipack packaging box 1 do not exist, Openings P2 are respectively formed. The first opening P1 refers to a side on which a tear opening piece that can be substantially removed by tearing is formed for convenience in explaining the present invention, and the second opening P2 refers to the present invention. For convenience in explanation, the side on which the stopper for preventing the rolling of the container is formed is said.

  In the embodiment of the present invention, the top plate 2 is cut on the first and second openings P1 and P2 side so that a part of the ring-shaped protrusion 95 formed on the peripheral edge of the top cover of the container can be seen. A notch 50 is formed (see FIGS. 1 and 8).

  Such a notch 50 is formed so that the can product can be drawn out as easily and easily as possible (improvement of take-out ease). That is, as shown in FIG. 8, canned beer can be taken out relatively easily by hooking and pulling a part of the ring-shaped protrusion 95 that is being looked at to the tip of the finger.

  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. However, in the present invention, the presence of the cutout portion 50 is not essential, and it is a matter of course that a multipack packaging box that does not include the cutout portion 50 may be used.

  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. Reference numeral 16 represents finger holes (two places), and reference numeral 17 represents a cut line. A tear line indicated by reference numeral 17 on the upper surface plate 2 forms an upper surface tear opening piece. The operation of tearing off the top tear opening piece is started from the side of reference numeral 17a in FIG.

(Description of the first essential structure of the present invention)
The first main part of the present invention is a tear opening that can be removed by tearing from the predetermined depth side position of the side plate toward the first opening P1 that is the front side of the side plate 3 and / or the side plate 4. The point is that a piece is formed. In the present embodiment, a case where a tear opening piece 40 is formed on one side plate 4 is illustrated. The back side position in the present invention indicates a location that progresses from the opening P1 to the middle of the side plate, for example, the vicinity indicated by reference numeral 41.

  As shown in FIG. 1, the tear opening piece 40 is formed with discontinuous cut lines along the form to be removed by tearing, and the final ends 47 a and 47 a of the cut lines at the time of tear removal are respectively openings. It is formed so as to be substantially directed to both ends of the folding line 4b of the folding piece 9 formed in the vicinity of the end portion of P1.

  Here, "substantially directed and formed" means that when the tear opening piece 40 is removed to form a container outlet, both ends of the folding line 4b of the folding piece 9 are used. This means that the opening piece 40 is removed. Thereby, the tear opening piece 40 can be easily separated from the packaging box body.

  In the tear removal operation, after the tear opening piece 40 has reached the positions at both ends of the folding line 4b of the folding piece 9, there is almost no tear resistance, and thereafter, the tear opening piece 40 can be torn and removed all at once.

  The shape of the tear opening piece 40 is preferably formed such that the tear width gradually increases from the back side position toward the opening P1 as illustrated. This is because after the tear opening piece 40 is removed, a hand is inserted from the removed side to facilitate removal of the product inside the packaging box body.

  Further, the shape of the tear opening piece 40 will be described in detail. As shown in FIGS. 1 and 2, the tear opening piece 40 includes a tear start window 41 formed in the vicinity of the back side position, and an opening side connected to the tear start window 41. It has a tear region forming part 45 extending to.

  The tear start window 41 has a hole that is large enough to allow a finger to be inserted, thereby facilitating opening. The tear region forming portion 45 has a region 45a in which a finger can be inserted into the tear start window 41 and a recess can be formed by folding or folding inward by pressing or pulling from the outside of the box. As a part, it can be torn to the first opening P1 side. Three cut lines 31, 32, 33 are formed further toward the tear start window 41 toward the tear start window 41, thereby assisting insertion of a finger into the tear start window 41, and After opening, a function of facilitating the removal of the container (a finger can be put in when removing the container located in the back) can be exhibited.

  The configuration of the tear region forming portion 45 will be described in further detail.

  The tear region forming portion 45 in the present embodiment includes a curved portion 46 that forms the vicinity of the tip of the tear opening piece 40, a cutout region 47 that is connected to the curved portion 46 toward the opening portion P <b> 1, and the curved portion 46 is arcuate. The fold line portion E (two fold line portions in the drawing) is formed so as to be drawn. The fold line portion E can act as a base portion of the flap piece when forming the recessed region 45a by the above-described flap-like folding.

  Due to the presence of the fold line portion E, the recessed region 45a formed by the flap-shaped folding is easily maintained in its original form (that is, the recessed portion is difficult to return to the original flat state), and the gripping operation is easily performed. Can be done.

  In addition, the tear start window 41 is desirably formed so as to be present in a gap position generated when the containers are adjacent to each other in relation to the container accommodated in the packaging box in order to reliably perform the gripping operation. That is, the canned beer containers accommodated in the multipack packaging box are arranged so as to stand upright at the bottom of the packaging box, and two 2 × 3 arrangement states (for example, two are visible in the opening P1 as shown in FIG. 2) ), The tear start window 41 is preferably formed so as to exist in a gap position (valley space) generated when the containers are adjacent to each other.

  In the case of the above arrangement form, the contact portion between the first container and the second container and the contact portion between the second container and the third container are located at gap positions (valley spaces). Will exist. The tear start window 41 may be formed at any gap position (valley space), but considering the box strength, ease of tearing operation, etc., the first gap position (valley space) from the opening P1. It is desirable to form the tear start window 41.

  The gap position (valley space) is clearly shown in the plan view of FIG. 8 and should be understood with reference to this drawing. FIG. 8 is a plan view of the multipack packaging box assembled as described above, as viewed from the top plate 2 side.

  Further, as shown in FIG. 1, the curved portion 46 connected from both sides of the tear start window 41 may be formed by a dotted cut line. In addition, the cut region 47 connected to the curved portion 46 has a “he” -shaped cut line, that is, a dotted cut line portion that forms the cut region 47, and a back side position of the dotted cut line portion. It is good to form with the cutting line of the shape of a "he" which is connected and has the line part cut into the inside of the tearing opening piece. However, it is not limited to the “he” -shaped cut line, and may be another cut shape such as a dotted line or a Y-shape.

  Further, the tear opening piece as shown in FIGS. 1 and 2 described above may be modified to a tear opening piece having a form as shown in FIG. 3, for example.

  The tear opening piece 40 shown in FIG. 3 is greatly different from that shown in FIG. 2 in that the tear start window 41 is not formed as shown in FIG. 2 in the form of FIG. There is no hole that has been made. That is, the tear opening piece shown in FIG. 3 has a tear start window forming portion 42 formed in the vicinity of the back side position, and a tear region 43 that is connected to the tear start window forming portion 42 and extends toward the first opening P1 side. The window forming portion 42 can form a recess (opening) by folding inwardly by pressing from the outside of the box so that tearing toward the opening can be started with this recess as a gripping portion. It has become.

  In order to make the tear opening piece 40 capable of tear removal easy to cut to the end, as shown in FIG. 1, it is usually formed at the position where both ends of the fold line 4b intersect with the fold lines 14b and 14b. The gusset hole to be formed is not formed in the present invention.

  When there is a gusset hole, when the tear opening piece is cut off, a part of the gusset remains without being cut out, and it is difficult to take out the container. By eliminating the gusset holes, the entire gusset can be cut out when the tear opening piece is cut out, making the container much easier to remove.

(Description of Second Essential Structure of the Present Invention)
As shown in FIG. 4, the second main part of the present invention is assembled with a stopper 60 for preventing rolling of the container projecting inward from the box at a position near the second opening P2 of the bottom plate. It is where it is formed.

  The container rolling prevention stopper 60 is mainly the container closest to the second opening P2 as shown in FIG. 4 (corresponding to the last container when the first opening P1 is used as a reference). However, it is formed in order to prevent rolling out of the second opening P2 (toward the front side in FIG. 4).

  The container rolling prevention stopper 60 is formed at a position close to the second opening P2 in the direction opposite to the side on which the tear opening piece 40 capable of tear removal described above is provided. The first opening P1 side where the tear opening piece 40 is provided corresponds to the original container outlet, and the second opening P2 at the opposite position corresponds to the last opening. When the container is taken out from the first opening P1 side, a container rolling prevention stopper 60 is formed to prevent the container located at the rearmost part from rolling backward further. That is, as shown in FIG. 4, the stopper 60 for preventing rolling of the container is disposed between the two containers so as to be engaged with the bottom peripheral edges of the last two containers 19 located on the second opening P2 side. It protrudes in a convex shape.

  The assembly member of the container rolling prevention stopper 60 will be described in more detail with reference to the drawings.

  The stopper 60 for preventing the container from rolling is a bent piece 61 formed on the bottom plate 5 shown in the upper left of FIG. 1 and the male side of the bottom plate 6 shown in the upper right end of FIG. It is formed by assembling the combined piece 8b (the hook piece 8b for fixing the form).

  As shown in FIG. 1, the bent piece 61 includes a punched flat surface portion 64 punched in a U-shape and a bent portion 66 connecting the two end points 64 a and 64 a of the punched flat surface portion. .

  The punching plane portion 64 is formed with stopper forming folding lines 64c and 64c from the two terminal ends 64a and 64a toward the substantially middle point of the punching opposing line 64b arranged in parallel with the bent portion 66. By such stopper forming folding lines 64c and 64c, the punching plane portion 64 has two triangular folding pieces 64d and 64d, and a triangular base that is connected to the two triangular folding pieces 64d and 64d. A shaped base 64e is formed. Strictly speaking, the stopper forming broken lines 64c and 64c are curved lines that slightly swell toward the triangular base 64e.

  The hook piece 8b used for fixing the shape located on the opposite side of the punched plane portion 64 and the developed view will be described in more detail. The hook piece 8b for fixing the shape is as shown in FIG. It has a hook plane part 81 that exhibits a hook function, and a bent base part 85 for raising the hook plane part 81. The hook plane portion 81 has an inclined side 86 extending from the end portion (outer base portion) of the bent base portion 85 and a jaw portion 87 formed on the upper side of the inclined side 86. The jaw portion 87 can be engaged with a convex portion in the vicinity of the apex of the punching opposing line 64b folded in an inverted V-shaped convex shape as will be described later.

  Hereinafter, an example of an assembly procedure of the container rolling prevention stopper 60 will be described in detail. This procedure is merely an example, and is not limited to this procedure.

  When assembling the multi-pack packaging box, the hook piece 8b shown on the right side of FIG. 1 is inserted through the female locking portion 7b shown on the left side of FIG. The male engaging piece 8c is also inserted through the female engaging portion 7c located on the left side of FIG.

  Thereafter, the hook piece 8b that is inserted is bent and the hook flat portion 81 (of the hook piece 8b) is bent and raised with the base 85 as a base line. Further, an operation of raising the punched flat portion 64 from the bent portion 66 by punching the bottom plate 5 into a U-shape is performed. Any of these operations may be performed first, or may be performed simultaneously. FIG. 5 shows a state in which these operations are completed, and the hook flat surface portion 81 and the flat surface portion 64 (the bent piece 61) are raised by the bending operation.

  Next, the stopper forming folding lines 64c and 64c are folded inward (so-called mountain folding) while the punching opposing line 64b of the bent piece 61 raised from the bending portion 66 is folded into an inverted V-shaped mountain fold. As a result, two triangular folded pieces 64d and 64d and a triangular base 64e serving as a base connected to the two triangular folded pieces 64d and 64d are formed. Thereafter, the jaw portion 87 of the hook piece 8b for fixing the form is engaged with the substantial middle point (near the vertex of the reverse V-shape) of the punching opposing line 64b folded into the reverse V-shape, and the inside of the box. A stopper for preventing rolling of the container protruding in a convex shape is assembled. The state after the assembly is shown in FIG.

  The inclined side 86 of the hook piece 8b can come into contact with the surface (inner surface in FIG. 6) constituting the triangular base 64e when assembling the stopper for preventing rolling of the container (see FIG. 6). ). As a result, the inclined position of the triangular base 64e raised obliquely is fixed, and the form of the stopper for preventing the rolling of the container can be stabilized.

  The two triangular folded pieces 64d and 64d of the stopper 60 for preventing rolling formed in this way engage with the peripheral edge of the bottom of the container (see FIG. 4), and the raised hook plane part 81 includes two containers. Intervened between.

  In the above-described embodiment, a so-called 6-can multipack packaging box having a 2 × 3 arrangement has been described. However, the same can be applied to a so-called 8-can multipack packaging box having a 2 × 4 arrangement. In the case of an 8-can multipack packaging box, the contact area between the first container and the second container, the contact area between the second container and the third container, the third container and the four containers It exists in a clearance gap position (valley part space) in three places of contact parts with an eye container. A tear start window or a tear start window forming portion may be formed in any gap position (valley space), but in this case as well, tearing starts from the first opening P1 to the first gap position (valley space). It is desirable to form a window and a tear start window forming part.

(Description of an example of specific packaging action)
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.

  Then, the side plates 3 and 4 are folded inward with the fold lines 2a and 2b as the boundary lines so as to cover the side portions of the canned beer, and the respective folding pieces 9 are folded inward, so that the top plate 2 and the side plates 3 and 4 The top gusset 10a is formed at the corner of the bottom plate 10 and the bottom gusset 10b is formed at the corner of the side plates 3, 4 and the bottom plate 5 and 6, and the bottom plates 5 and 6 are formed so as to cover the bottom of the canned beer. The folding lines 3a and 4a are folded inward with the boundary lines as the boundary lines, and the concave portion b of the first locking portion 8a on the male side provided on the bottom plate 6 is formed in the laterally long side of the first locking portion 7a on the female side of the bottom plate 5. Canned beer is packaged by engaging with one side a forming a square hole. In order to prevent the engagement from dropping off, the hooks 8b for fixing the shape provided on the bottom plate 6 and the engagement pieces 8c on the male side are respectively engaged with the female side provided on the bottom plate 5 from the head. The hooks 8b and the engagement pieces 8c are secured to each other through the slits of the stop portions 7b and 7c to prevent the hook pieces 8b and the engagement pieces 8c from coming off.

  Next, the stopper 60 for preventing rolling of the container is assembled, for example, according to the above-described assembly procedure.

  When the pack sheet 1 is turned over so that the side plate 4 faces upward, a perspective view as shown in FIG. 2 is obtained.

  In addition, a multipack packaged product is completed by storing a container in the above-mentioned multipack packaging box.

(Description of an example of operation for removing the tear opening piece 40)
To tear and remove the tear opening piece 40 of the multipack packaging box inserted into the shelf with the first opening P1 on the near side as shown in FIG.
