[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
[0018]
FIG. 1 is a view showing a deployed state of a carton as a preferred embodiment of the packaging material of the present invention. FIG. 2 is a view showing a state where the carton shown in FIG. 1 is formed in a box shape. In the carton (packaging material) 100, for example, a container for a beverage such as beer can be stored. Here, the container of beer or the like may be housed in the carton 100 in an independent state, or may be housed in the carton 100 after being packed as a multi-pack in a predetermined number unit. In this specification, unless otherwise specified, a packaging material or a carton includes both an unfolded state (a state before packaging a container) and a box state (a state after packaging a container). Is used to mean
[0019]
In the carton 100 in the box state, four of the six surfaces are configured by the pair of wide surface portions 11 and 12 and the pair of narrow surface portions 21 and 22. One of the remaining two surfaces may be constituted by flaps 31 and 33, and the other of the remaining two surfaces may be constituted by flaps 32 and 34.
[0020]
The carton 100 in the unfolded state (plate state) has the connecting portion 41 fixed to the wide surface portion 11 so that the narrow surface portion 22 is connected to the wide surface portion 11, and the flaps 35 and 37 are arranged inside the flaps 31 and 33. The flaps 31 to 38 are bent at right angles so that the flaps 36 and 38 are disposed inside the flaps 32 and 34, and the outer flaps are fixed to the inner flaps, thereby forming a box state. In addition, such a format is called a wrap round type.
[0021]
The first wide surface portion 11 includes a pair of first tear rows 11a and 11b as first tear portions extending inward from the first end portion 11i to the first wide surface portion 11 and a first wide portion from the second end portion 11j. A pair of second tearing rows 11c and 11d as second tearing parts extending inwardly of the surface part 11, and third tearing parts extending between the first tearing rows 11a and 11b and the second tearing rows 11c and 11d, respectively. And a pair of third tearing rows 11e, 11f.
[0022]
Here, it is preferable that the second end 11j is opposite to the first end 11i. Preferably, the flap 31 is connected to the first end 11i, and the flap 32 is connected to the second end 11j.
[0023]
The pair of first tearing rows 11a and 11b are formed so as to extend from both ends (corners or vertexes of the first wide surface portion 11) of the first end portion 11i or the vicinity thereof toward the inside of the first wide surface portion 11. Is preferred. Accordingly, a wide opening can be formed when the box-shaped carton 100 is opened, and the packaged object can be easily taken out. Furthermore, it is preferable that the pair of first severing rows 11a and 11b be formed such that the distance between them becomes smaller as the distance from the first end 11i increases. Thereby, the strength of the box-shaped carton 100 at the time of opening can be maintained to a certain extent, and it is possible to prevent the articles to be packaged that should be left without being taken out of the carton 100 from falling off. It is preferable that the second tearing rows 11c and 11d have the same configuration as the first tearing rows 11a and 11b.
[0024]
Each of the first, second, and third nicks may be constituted by a single nick row instead of a pair of two or more nick rows separated from each other. In this case, the box-shaped carton 100 After being cut by one slicing row, the part freed by the slicing is pulled in the outer direction of the carton 100 so as to open in a double-opened manner with the boundary (ridge) between the wide surface portion and the narrow surface portion as an axis. Can be done.
[0025]
The above-described cut portion can also be formed on the second wide surface portion 12. By forming the cut portions on both the first wide surface portion 11 and the second wide surface portion 12, the degree of freedom in taking out the container as the article to be packaged can be improved. However, when importance is placed on the strength of the carton 100, the cut portion should be formed only on one of the two wide surface portions 11 and 12.
[0026]
In the example shown in FIG. 1, the second wide surface portion 12 is also formed with cut portions 12a to 12h. That is, the second wide surface portion 12 includes a pair of first tear lines 12a and 12b as first tear portions extending inward of the second wide surface portion 12 from the first end portion 12i, and a second cut surface from the second end portion 12j. A pair of second slicing rows 12c and 12d as second slicing sections extending inward of the wide surface portion 12, and third slicing extending between the first slicing rows 12a and 12b and the second slicing rows 12c and 12d, respectively. A pair of third tearing rows 12e and 12f are formed as parts.
[0027]
Here, the tearing row is used to open a part of the carton 100 in a box state (for example, parts denoted by reference numerals 200 and 210 in FIG. 3) and to cut the carton 100 when taking out a container as an article to be packaged. Is formed. In other words, the carton 100 is configured to be cut at the portion of the severing row, so that the opener can access the package inside from the outside of the carton 100.
[0028]
In the carton 100, the tearing rows 21 a, 21 b, 22 a, 22 b for dividing the carton 100 in a box state into two may be formed in the narrow surface portions 21, 22. The opener removes the band portion defined by the pair of tearing rows 21a and 21b at both ends and the band portion defined by the pair of tearing rows 22a and 22b from the carton 100, thereby dividing the box-shaped carton 100 into two. Can be split. Here, it is preferable to form the cuts 21c and 22c at appropriate portions of the band portion. The unsealing person can start tearing the band portions starting from the cut portions 21c and 22c by inserting a finger or the like into the cuts 21c and 22c and pulling the band portions.
[0029]
The first tearing rows 11a, 11b, 12a, 12b as the first tearing parts facilitate the first wide surface portions 11, 12 only from the first ends 11i, 12i toward the inside of the first wide surface portions 11, 12. Although it is preferable to form it so that it can be torn, it may be formed so that it can be easily torn in the opposite direction. The second slicing rows 11c, 11d, 12c, 12d as the second slicing portions facilitate the second wide surface portions 11, 12 only from the second ends 11j, 12j toward the inside of the first wide surface portions 11, 12. Although it is preferable to form it so that it can be torn, it may be formed so that it can be easily torn in the opposite direction. The arrows in FIGS. 1 and 2 indicate directions in which the tearing is easy.
[0030]
The third tearing rows 11e, 11f, 12e, and 12f as the third tearing portions are directed from the first tearing rows 11a, 11b, 12a, and 12b to the second tearing rows 11c, 11d, 12c, and 12d, respectively, and in the opposite direction. , So that it can be easily torn in two directions. Here, it is preferable that the third cut portion is formed so as to be able to cut with substantially the same force in any of the two directions. Thus, regardless of how the carton 100 is placed, the force required to partially open the carton 100 becomes substantially the same.
[0031]
Hereinafter, the first and second cut portions are formed so that the wide surface portion can be cut in at least one direction (a direction toward the inside of the wide surface portion), and the third cut portion can be cut in both directions. The advantage of the structure formed as described above will be described with reference to FIG.
[0032]
FIG. 3 is a diagram illustrating a state in which a can, for example, a beer can is taken out from the box-shaped carton 100 as a packaged object. In FIG. 3, the carton 100 is placed on the floor with the surface formed by the flaps 32 and 34 facing downward. When the carton 100 is placed in such an arrangement, first, the flap 31 is opened, and then the flap 31 is pulled toward the front, so that the flap 31 is widened by the pair of first tear rows 11a and 11b as the first tear portions. The surface portion 11 is cut off, and the wide surface portion 11 is cut off by a pair of third cutting lines (cutting lines capable of cutting in both directions) 11e and 11f, and a part of the carton 100 (portion denoted by reference numerals 200 and 210) is cut. Open. Thus, the multi-pack 50 of the beer can 40 can be taken out of the carton 100 through the opening. Here, by opening the flaps 33, 35, and 37, the multipack 50 can be more easily taken out.
[0033]
Here, when the second tearing rows 11c and 11d are easily formed in only one direction (the direction toward the inside of the wide surface portion 11), the second tearing rows 11c and 11d remain without being torn. Therefore, it is possible to prevent the multipack 50 stored below from dropping off during transportation or the like.
[0034]
As shown in FIG. 1, when the cut portions are formed on both of the two wide surface portions 11 and 12, the flap 33 may be pulled to cut the wide surface portion 12, contrary to the above description.
[0035]
Next, a case where the carton 100 is placed on the floor with the surface constituted by the flaps 31 and 33 facing downward will be described. First, the flap 32 (or 34) is opened, and then the flap 32 (or 34) is brought forward. , The wide surface portion 11 is torn by a pair of second tearing rows 11c and 11d (or 12c and 12d) as a second tearing section, and further a pair of third tearing rows (a tearing row capable of tearing in both directions). ) The wide surface portion 11 (or 12) is cut off at 11e and 11f, and the carton 100 is partially opened. Here, by also opening the flaps 34 (or 32), 36, and 38, it becomes easier to take out the multipack 50.
[0036]
Further, when the carton 100 is placed on the floor with the second wide surface portion 12 facing downward, the first wide surface portion 11 may be cut from the flap 31 side or the flap 32 side. Conversely, when the carton 100 is placed on the floor with the first wide surface 11 facing downward, the second wide surface 12 may be cut from the flap 33 side or the flap 34 side.
[0037]
Further, when the carton 100 is placed on the floor with the narrow surface portion 21 or 22 facing downward, any one of the flaps 31, 32, 33, and 34 may be pulled and the wide surface portion following the flap 31 may be cut with the tearing portion.
[0038]
In order to make it easy for the wide surface portions 11 and 12 to bend a band-like portion (the trapezoidal portion 210 in FIG. 3) which is pulled during the opening operation as described above, a notch for folding or a ruled line (dent) 11g, 11h is provided. , 12g and 12h may be formed. For example, when the carton 100 is partially opened as shown in FIG. 3, the carton 100 is pulled forward in FIG. 3 in a state where the wide surface portion 11 is cut to the last part of the pair of first cutting rows 11 a and 11 b. The strip-shaped portion (the trapezoidal portion 210 in FIG. 3) is easily bent forward with the cut 11g as a hinge. This makes it possible to easily start the tearing of the third cut rows 11e and 11f, and to prevent the band-shaped part from being unsightly due to being bent at an arbitrary part.
[0039]
As described above, according to the double-opening structure of the preferred embodiment of the present invention, the carton 100 is partially opened and the multipack 50 to be packaged is opened regardless of how the carton 100 is placed (orientated). Can be easily taken out. Note that such an effect can be obtained even when an independent can 40 (that is, a can not packaged by the multipack 50) is stored in the carton 100.
[0040]
In the example shown in FIGS. 1 to 3, the tear rows 11 e, 11 f, 12 e, and 12 f, which are easy to tear in both directions, are configured by arranging semi-circular or arc-shaped cuts intermittently and in a line.
[0041]
The row of tears in which the carton 100 can be easily torn in both directions is not limited to the examples shown in FIGS. 1 to 3 and can be realized in various forms. Hereinafter, another embodiment of the tearing row in which the carton 100 can be easily torn in both directions will be exemplarily described with reference to FIG. 4 can be employed in place of the tear rows 11e, 11f, 12e, and 12f shown in FIGS. Here, in any of the examples shown in FIGS. 4A to 4F, the wide surface portion is partially cut off by cutting out the band portion from the wide surface portion of the carton, and the wide surface portion of the carton is partially opened. can do.
[0042]
In the examples shown in FIGS. 4A to 4F, the strip 300 can be cut in any of two directions (left direction and right direction in the figure). However, the belt-like portion may have a structure that can be cut off in only one direction. Also in such a case, the two strip-shaped portions 300 corresponding to the tearing rows 11e and 11f on both sides of a portion to be opened (for example, a portion denoted by reference numeral 200 in FIG. 3) in the wide surface portion are cut off. You can open the part you want to open.
[0043]
In the example of the slicing row shown in FIG. 4A, semi-circular or arcuate cuts are intermittently arranged in two rows.
[0044]
In the example of the tearing row shown in FIG. 4B, cuts having straight portions at both ends of a semicircular or arcuate portion are intermittently arranged in two rows.
[0045]
In the example of the tearing row shown in FIG. 4C, a semicircular or arcuate cut and a linear cut are alternately arranged in two rows.
[0046]
In the example of the tearing row shown in FIG. 4D, a semi-circular or arc-shaped notch convex in the first direction, and a semi-circular or arc-shaped notch convex in the second direction opposite to the first direction. Are arranged alternately.
[0047]
In the example shown in FIG. 4E, linear cuts are intermittently arranged, and when a band is cut from right to left, a band formed by two inner cuts is cut and left. When the band is cut rightward from, the band formed by the two outer cuts can be cut.
[0048]
In the example shown in FIG. 4 (f), unit cuts composed of straight cuts along the cut direction and straight cuts not parallel to the cut direction are intermittently arranged. In this example, when the band is cut from right to left, the band formed by the two inner cuts is cut out, and when the band is cut from left to right, the outer two cuts are formed Can be cut off.
