Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention is made of cardboard having a simple structure for packaging a plurality of cans such as cans, bottles, plastic bottles or liquids, powders, solids, etc., for liquids such as beer and juice. Regarding storage case.

[0002]

[Prior art]

 As a storage case in which a plurality of cans are simply packaged so that the purchaser can carry them conveniently, various types of structures such as those disclosed in Japanese Patent Laid-Open No. 5-112373 have been proposed.

As shown in FIG. 3, a known storage case of this kind has an open mouth at four corners C and D of an open mouth B at both ends of a square tubular storage case A formed by folding with cardboard. Closing hypotenuses E and F are bent so as to partially block B, and the can body G is prevented from falling out of the opening B.

The storage case A shown in FIG. 3 is formed by mechanically folding at high speed from a blank H formed by punching, the half of which is schematically shown in FIG.

In the known example shown in FIG. 4, left and right side walls J are connected to the top wall I, a half bottom wall K is connected to the side wall J, and the insertion engagement portion L engages to form a rectangular tubular shape. It is molded into the storage case A.

Due to the folding molding of the closing oblique sides E and F, a first inward folding line O is formed inward of the edge N of the edge M at the symmetrical position of the side wall J in parallel with the edge N. A punching window hole Q is formed in a portion of the first inward folding line O near the ridge line P, and the outer folding line R and the top wall I and the bottom wall L intersect obliquely at a position near the center of the edge N from the punching window hole Q. The second internal folding line T is formed so as to cross the edge S of the.

To form the blank H shown in FIG. 4, it is essential to remove the punched pieces of the punched window hole Q, and the walls I, J, K are removed from the blank H from which the punched pieces have been removed. At the same time as folding and folding the edge M until it abuts against the inner side surface of the side wall J, the closing oblique sides E and F are formed by bending the outer fold line R and the second inner fold line T.

[0008]

[Problems to be solved by the device]

 In the conventional can-shaped storage case A, in the mechanical high-speed continuous punching forming process of the blank H, the workability of removing the punching piece for forming the narrow punching window hole Q is remarkably poor. In addition to reducing the production efficiency, window holes Q appear on the oblique sides E and F for closing, impairing the appearance.

Therefore, in the present invention, the punching piece removing step is completely unnecessary even though it has the same function as that of the conventional storage case shown in FIGS. 3 and 4, and holes or the like are present in the oblique side for closing. It is an object to provide a storage case that has a good appearance without being forgotten.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, according to the present invention, at least one pair of opposing first edges out of two pairs of opposing edges at the opening ports at both ends of a cardboard storage case formed in a rectangular tube shape. A first inward folding line was formed on the edge, inside the edge, substantially parallel to the edge and close to the edges on both sides of the first edge.

An outwardly swelling slit is formed between the first inner fold line and the ridge edge, and an outer fold line is formed from a part of the slit in a direction oblique to the first edge line. Formed.

Further, a second inward folding line is formed from the intersection of the slit and the ridge in a direction obliquely intersecting with another pair of second edges continuous with the ridge.

By forming each of the folding curves, the first edge is made into a bent edge that abuts the inner side surface of the storage case, and the closing slant is provided at the opening portion between both ends of the bent edge and the second edge. It was positioned so that the can-like body could be prevented from falling out, and the removal of punched pieces during the molding process was completely unnecessary.

[0014]

[Embodiment of device]

 FIG. 1 shows a developed state of a blank 1 of an embodiment, and FIG. 2 shows a molded storage case 15. The blank 1 has left and right side walls 3 and 4 continuous with a top wall 2 and a side wall 3. , The bottom walls 5 and 6 of the respective halves that are continuous with 4 are stamped and formed by a piece of cardboard.

The bottom wall 5 of the one half has window holes 7 for engagement and a group of slits 8 for engagement, and the bottom wall 6 of the other half is inserted into the slit 8 and locked. Group of locking pieces 9 and a group of ear pieces 11 that are locked to the side edges 10 of the window hole 7 are formed, and the connecting portions of the bottom walls 5, 6 and the side walls 3, 4 are A group of locking holes 12 is formed to engage with a winding edge on the outer circumference of the lower bottom of the can body to be stored. In the figure, reference numerals 13 and 13 are outer bending lines provided between the walls, and reference numeral 14 is a slit for forming a finger-holding hole for grasping.

The pair of opposite edges 17 and 18 and the edges 19 and 20 of each two pairs in the opening 16 at both ends of the rectangular tubular storage case 15 shown in FIG. 2 formed from the blank 1 shown in FIG. Of the pair, in the illustrated example, one of the edges 17, 18 is hereinafter referred to as a first edge 17, 18, and as shown in FIG. 1, the edge 21, 18 is located inside the edge 21, 22. First inward folding lines 25 and 26 are formed in parallel with the first edge 17 and 18 up to the ridge edges 23 and 24 on both sides.

Between the ends 27, 28, 29, 30 of the first inward folding lines 25, 26 and the ridge edges 23, 24, slits 31, 32, 33, which bulge outward in an arc shape, are formed. 34 are formed.

Outer bending lines 35, 36, 37, 38 are formed so as to obliquely intersect each part of the slits 31 to 34, in the illustrated example, from the substantially central portion toward the center of the first edge 17 or 18. There is.

Further, from the intersection points 39, 40, 41 and 42 of the slits 31 to 34 and the ridge edges 23 and 24, another pair of second edge sides 43, 44 and 45 continuous with the ridge edges 23 and 24, and Second inward folding lines 46, 47, 48, 49 are formed in a diagonal direction.

The outer fold lines 35 to 38 in the illustrated example are formed with slits 50, 51, 52 and 53 orthogonal to the edges 21 and 22 at positions close to the edges 21 and 22, respectively. 50 to 53 are not always required.

The first and second inner and outer folding lines described above are also formed with the same structure on the edges 54, 55, 56, 57, 58 forming the other opening 16.

In the storage case 15 according to the present invention, the first edges 17, 18 and the corresponding edges 54, 55 are bent until they come into contact with the inner side surfaces of the side walls 3, 4 to form bent sides. As a result, the paper material in the band surrounded by the slits 31 to 34, the outer folding lines 35 to 38, and the second inner folding lines 46 to 49 is provided at both ends of the bent side at the opening 16 portion. Formed on the closing oblique sides 60 1, 61, 62, 63 located between the second side edges 43, 44, 45 and prevents the can-like body 59 from falling out from the opening 16 of the storage case 15.

The bent sides formed by the first edges 17 and 18 and the corresponding edges 54 and 55 that are bent until they come into contact with the inner surfaces of the side walls 3 and 4 are stored in a storage case. Since the strong side-holding function is exerted by being pressed by the side surface of the can-shaped body 59, the closing hypotenuses 60 to 63 exert a strong can-shaped body slip-out preventing function.

Furthermore, the protrusions 64 or 67 remaining on the edges of each wall due to the formation of the slits 31 to 34 obscure the bent corners generated by the folding of the closing oblique sides 60 to 63, and thus the appearance of the storage case is improved. To do.

In the illustrated embodiment, the slits 31 to 34 are formed in an arc shape, but as long as the slit has a triangular shape, a quadrangular shape, or the like that can bulge outward, it has a special shape. Does not exist.

[0026]

[Effect of device]

 The present invention has the above-described structure and operation. Since the closing hypotenuse is formed at the corner portion of the open mouth of the storage case, the narrow window hole required in the prior art is replaced by the outside window. Since it suffices to form the slits 31 to 34 having a shape that bulges laterally, the step of removing small punched pieces due to punching of a small window hole is completely unnecessary, and it is possible to improve the production efficiency. .

Further, by forming the slits 31 to 34, when the closing oblique side is bent and formed, the projecting pieces 64 to 67 remain on each wall edge, and the projecting pieces 64 to 67 are bent corners of the closing oblique side. Since the part is covered, it also has an effect of keeping the appearance of the storage case good.
