Description

  The present invention relates to a carton that accommodates a plurality of articles such as cans, and more particularly to a carton that is easy to assemble and can greatly reduce raw material costs.

  2. Description of the Related Art Conventionally, cartons for storing a plurality of articles such as beverage cans such as soft drinks for distribution and use by consumers have been provided. When a consumer purchases such an article, the consumer carries the article in a carton unit, and when taking out the article, the consumer destroys the carton and takes out the article.

  In general, as a carton for storing articles, a box-shaped carton including a top wall panel, a bottom wall panel, and front, rear, left and right side wall panels has been used for a long time. However, in a box-shaped carton, since it is necessary to cover the entire article to be accommodated, the amount of cardboard or the like used as a raw material is large, and improvement in cost has been demanded.

  As a carton that has improved the problems of the box-shaped carton, a so-called round-up carton having a cylindrical structure having a top wall panel, a bottom wall panel, and a pair of side wall panels and having an open front end and rear end is also widely used. . This round-up carton has the advantage that the use amount of the carton blank raw material is reduced because it has an opening, and the contained article can be seen from the outside, but the front end and the rear end are open and the article is open. Since there is a risk of falling off, many structures for preventing the dropping of articles have been devised.

  As such an article drop-off preventing structure, a carton having a closed structure at an opening, a carton that engages with a concave portion of an article to be accommodated, and the like to prevent individual articles from dropping off are disclosed. As such an example, for example, a round-up carton comprising a top wall panel, a side wall panel, and a bottom wall panel, and a flap formed by cutting out a part of the top wall panel and a part of the bottom wall panel, A carton is disclosed that can be folded into the upper part and engage the flaps with the recesses at the top and bottom of the article to prevent the carton from falling off (see, for example, Patent Documents 1 and 2).

  However, the carton described in the above-mentioned patent document has a certain effect with respect to the structure for preventing the dropout of the article, and although the amount of raw material used is reduced as compared with the box-shaped carton, it covers most of the article except the opening. Since it is necessary to form a cylindrical structure, there is still room for improvement in the amount of raw materials used in the carton.

  The present invention has been made in view of the above circumstances, and can reduce costs by using less raw materials than conventional cartons, and can securely fix and store articles, and easily. It is an object of the present invention to provide a carton and a carton blank that can achieve automation by a simple assembly process.

  The present invention is a carton for arranging and holding cylindrical articles such as a plurality of cans in a triangular shape so that their circumferential side surfaces are in contact with each other, and is an abbreviation for holding a plurality of triangularly arranged articles. A triangular bottom wall panel, a substantially triangular top wall panel, and three side wall panels that hold part of the side surfaces corresponding to the three triangular sides of the side surfaces of a plurality of articles arranged in a triangular shape; And at least one of the top wall panel and the bottom wall panel is engaged with at least one article in the opening. A flap is provided, and the article engaging flap is engaged with the bottom and / or top of the article to fix the article.

  In the carton of the present invention having the above-described configuration, the article engaging flap is engaged with at least one of the top and / or the bottom of the article to be housed to prevent the dropout firmly. The top and bottom wall panels are connected to each other to hold the article by covering only a portion of the side of the article arranged in a triangular shape without covering the majority of the article side like a carton, Furthermore, since the top wall panel and the bottom wall panel only cover the top and part of the bottom of the article, the amount of carton raw material used is greatly reduced. In addition, since the articles to be accommodated are arranged in a triangular shape in contact with each other, when a plurality of units are arranged in the front, rear, left, and right with a carton containing a plurality of articles as a minimum unit, As a result, it becomes a hexagonal close-packed arrangement, which contributes to a reduction in accommodation space.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the carton that holds the three articles shown in FIG. 1 will be described as an example. However, the present invention is not limited to the carton and the carton blank. For example, the six articles shown in FIG. Any carton can be produced as long as it is within the range specified in the present invention, such as a carton to be held or a carton to hold more articles.

  FIG. 3 shows a blank 1 for forming a carton for accommodating a plurality of articles such as cans, which is made of cardboard or a similar foldable sheet material. In FIG. 3, the blank 1 includes a bottom wall panel 10, a first side wall panel 11, a top wall panel 12, a second side wall panel 13, and a third side wall panel 14, which are crease lines 20 to 23. Are continuously connected in a foldable manner. By folding these panels, the carton shown in FIG. 4 is formed, and articles such as cans can be held as shown in FIG. Various flaps and slits described below are formed on the panels 10 to 14 and the edge of the panel.

  The bottom wall panel 10 has a substantially triangular shape (hexagonal shape) in which a portion corresponding to the apex of the triangle is cut off, and the bottom article engagement flap 30 is continuously foldable through a crease line 24 on three sides thereof. It is connected. Similarly, the top wall panel 12 has a substantially triangular shape (hexagonal shape) in which a portion corresponding to a vertex of the triangle is cut off, and the top article engagement flaps 31 and 32 are connected to the three sides of the top wall panel 12 via the crease lines 25 and 26. Are continuously connected in a foldable manner. In the assembled state of the carton, the article engaging flaps 30 to 32 are folded inwardly through the crease lines 24 to 26, and the top surface and the bottom surface of the article to be stored are fixed to each other to fix the article. Prevent falling out.

  A glued flap 33 is continuously connected to the edge of the second side wall panel 13 and the third side wall panel 14 on the opposite side to the top wall panel 12 via a fold line 27 so as to be foldable. The gluing flap 33 is glued to the bottom wall panel 10 to connect the second side wall panel 13 and the third side wall panel 14 to the bottom wall panel 10 to form a closed structure of the carton.

  On the top wall panel 12, a zipper 41 made up of a plurality of character-shaped cut lines is formed, and on the top article engagement flap 31, the break is defined by a semi-arc-shaped cut line 40. A starting point flap 34 is formed, and is continuously connected to the top wall panel 12 via the crease line 25 so as to be foldable. The opening of the carton is performed by holding the breaking start flap 34 and breaking the zipper 41.

In order to assemble the carton from the carton blank 1 shown in FIG. 3, a continuous bending operation is performed. The bending operation is performed without reversing or rotating the blank or carton with a linear machine line. The following shows the procedure, but the present invention is not limited to the following examples.

  First, the first side wall panel 11, the second side wall panel 13, and the third side wall panel 14 are bent vertically upward along the fold lines 21 to 23 of the carton blank 1 placed horizontally. The glued flaps 33 formed at the end portions of the second side wall panel 13 and the third side wall panel 14 are folded 90 ° inward of the carton along the fold line 27 to keep both glued flaps 33 horizontal and directed outwardly of the carton. Glue the surface. The bottom wall panel 10 is bent 90 degrees inward of the carton along the crease line 20, and the bottom wall panel 10 and the glued flap 33 are bonded together to complete the carton having openings in three directions shown in FIG. The above is assembled with the top wall panel downward and the bottom wall panel upward, but the same is true when both are upside down.

  Subsequently, the top article engaging flaps 31 and 32 and the bottom article engaging flap 30 are bent 180 ° inward into the carton along the crease lines 24 to 26, and these are closely attached to the top wall panel 12 and the bottom wall panel 10, respectively. . Finally, a cylindrical article such as a can is inserted from the three openings, and a carton package containing three articles is completed as shown in FIG. When the package is opened, the zipper 41 can be broken by pulling the breaking start flap 34, and the article can be taken out.

  As shown by the broken line in FIG. 1, the top article engagement flaps 31 and 32 are folded 180 ° inward of the carton, but strictly speaking, they are not in close contact with the top wall panel, and the restoring force of the carton material Therefore, the top wall panel 12 / bottom wall panel 10 and the top article engagement flaps 31, 32 / bottom article engagement flap 30 are actually opened at a certain angle. By this opening, the edges of the top article engagement flaps 31, 32 / bottom article engagement flaps 30 are engaged with the recesses at the top / bottom of the article, and the article is prevented from dropping out of the carton.

  The carton of the present invention can firmly hold the article by the mechanism as described above and prevent the article from falling off. Further, as is apparent from FIG. 1, the top wall panel and the bottom wall panel cover only a part of the article without covering the entire top and bottom of the article, and the side wall panel is also a part of the side surface of the article. Since the top wall panel and the bottom wall panel are connected so as to cover the part, the amount of raw material used in the carton is greatly reduced.

  Since the articles to be accommodated are arranged in a triangular shape in contact with each other, when a plurality of units are arranged in the front, rear, left, and right with the minimum unit of a carton in which three articles are accommodated, the accommodated articles as a whole It becomes a hexagonal close-packed arrangement (honeycomb arrangement) and contributes to a reduction in storage space as compared with a conventional carton of articles arranged squarely in the vertical and horizontal directions. Furthermore, compared with the conventional square array carton, the triangular array carton and the hexagonal close-packed array of products using the same are visually unique and can appeal to the buyer.

  In the above-described embodiment of the present invention, the second side wall panel, the third side wall panel, and the bottom wall panel are connected by the glued flap. However, the present invention is not limited to this means. Arbitrary connecting means such as a means for providing a lock flap on one side of the panel and a lock flap receiving slit on the other side to connect them can be provided.

  In the above description, a carton that holds three articles is illustrated, but a carton that holds six articles as shown in FIG. 2 can also be produced. Since the basic configuration of this carton conforms to the carton of FIG. 1, detailed description is omitted, but as with the carton described above, six articles are arranged in a triangular shape, and a substantially triangular top wall and bottom wall are arranged. Can be held by a panel and three sidewall panels. The appearance of this carton is also unique, and it is possible to add a novel appeal to the product. In addition, the hexagonal close-packed arrangement that contributes to space saving is also possible. Furthermore, it is possible to produce a carton or the like that can accommodate four triangular arrays on one side, that is, ten articles.

  In the carton shown in FIG. 1 (and FIG. 2), an example in which a total of six article engagement flaps are provided in the three openings of the top wall panel and the bottom wall panel has been described. It can be changed. For example, an article engagement flap is provided only on one of the top wall panel or the bottom wall panel, and the article is engaged with only the top or bottom of the article. Also in such a form, since one of the top part or the bottom part of the article is engaged and the other is pressed by the wall panel, the article can be held. In this case, since the article engagement flap is provided only on one side, the amount of the carton raw material used can be reduced.

  It is also possible to provide the top / bottom article engagement flaps of the present invention at only one or two of the three openings. In that case, it is possible to provide a conventional arbitrary open end connection structure in the opening without the article engaging flap, or a closed structure without providing the opening.

  The carton of the present invention may be provided with a gripping means by punching and forming a gripping flap on the top wall panel or by forming a hole through which a finger can be inserted into the top wall panel.

  The terms used in the above description for directions such as top, bottom, edge, front, back, inside, and outside do not limit each panel to such a direction, but simply distinguish the panels from each other. It is only for the purpose. The term crease line does not necessarily refer to a single crease line, and can easily be one or more score lines, for example, perforations or lines thinned by press embossing, etc. without departing from the scope of the present invention. It may be a line that bends or bends. The present invention can also be applied to cartons of articles having various arrangements without departing from the scope of the invention.

  As described above, according to the present invention, the cost can be reduced by using a small amount of raw materials, the article can be securely fixed and accommodated, and automation can be achieved by an easy assembly process. Also possible carton and carton blank can be provided.
