Description

  The present invention relates to a carton that accommodates an article, and more particularly, to a carton that is easy to assemble, can hold an article firmly, 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 in a carton unit, the consumer carries the carton by a gripping means formed on the top of the carton, and takes out the article by destroying the carton when taking out the article.

  Generally, in a carton that contains articles, a box-like carton comprising a top wall panel, a bottom wall panel, and front, rear, left and right side wall panels, or a part of the box-like carton is cut out to have a window portion. A carton that can be confirmed, or a so-called round-up carton that has a top wall panel, a bottom wall panel, and a pair of side wall panels, has a cylindrical structure with an open front end and rear end, and can confirm the contents. It has been known. Furthermore, many cartons are known, such as a carton having a partially closed structure (side wall panel) at the opening of the round-up carton, or a carton that covers and grips only the top of the article. . Some of these cartons have a grip portion at one end of the top wall panel or a part of the top wall panel, and are thus carried and displayed.

  A carton having a large area covering an article such as a carton or a box-like carton having a closed structure at the opening of a round-up carton can hold the article firmly and is preferable from the viewpoint of strength, but the panel constituting the carton The number of carton materials used is large and the raw material cost is increased. On the other hand, round-up cartons that do not have a closed structure or cartons that hold only the top of an article have a simple structure and low cost, but have problems with strength, and the carton breaks during use. There was a problem that the articles were easily dropped.

  For such a problem, a plurality of article pressing flaps are provided by cutting out a part of the top and bottom walls of the round-up carton, and the article pressing flaps are folded inwardly into the carton so that the top and bottom of the article such as a can A carton that fixes an article by pressing is disclosed (for example, see Patent Document 1).

  However, in this carton, the flap is simply folded inward of the carton via the straight crease line, so that, for example, when the flap is folded 180 degrees with respect to the wall panel, Since the article is in close contact with the back side of the wall panel and is not in contact with the article, the article cannot be pressed, and there is a problem that the fixing force of the article is insufficient.

  As a round-up carton that can solve this problem, a triangular panel is provided on a part of the crease line connecting the article pressing flap and the top wall / bottom wall punched out on the top wall / bottom wall of the carton. A carton that fixes an article by folding a flap and a triangular panel inward of the carton is disclosed (see, for example, Patent Document 2). According to this carton, since the two surfaces that are inclined to each other such as the article pressing flap and the triangular panel protrude inward of the carton, the article pressing flap does not adhere to the top wall panel, and presses and fixes the article. The triangular panel is caught on the article and can be prevented from falling off.

  However, in this carton, only the articles arranged at both openings of the cylindrical structure are fixed, and the articles arranged between these articles are not provided with a flap for fixing, The fixing of the articles in both openings only prevented the internal articles from falling off. Therefore, when the article in the opening is dropped, there is a problem that the article in the inside is also dropped.

  As a carton capable of solving this problem, a carton is disclosed in which an engagement flap formed by punching a part of a top wall panel is folded inwardly to engage with a recess at the top of the article to fix the article. (For example, Patent Document 3). According to this carton, the internal article sandwiched between the articles in both openings can be fixed.

  However, in this carton, since there is no means for fixing the folded engagement flap, the engagement portion with the article is easily removed by the restoring force of the engagement flap outward of the carton, and the fixing force is sufficient. I couldn't.

  The present invention has been made in view of the above situation, and an object of the present invention is to provide a carton that has a simple and low-cost component and can firmly fix an article.

  The present invention is a carton for arranging at least three articles in rows and holding at least one row, and includes a bottom wall panel, a pair of side wall panels, and a top wall panel for forming a cylindrical structure. A plurality of panels are provided, and a top engagement fixing portion formed by punching a part of the top wall panel is foldably connected to the top wall panel via a crease line, and by punching a part of the top wall panel A bottom formed by punching a part of the bottom wall panel, wherein the formed top pressing flap is partly connected to the top wall panel via the crease line and partly foldable to the top engaging fixing part The engagement fixing part is foldably connected to the bottom wall panel via the crease line, and the bottom pressing flap formed by punching out a part of the bottom wall panel is partly connected to the bottom wall panel via the crease line, Or A part is foldably connected to the bottom engaging fixing part, and the top / bottom engaging fixing part and the top / bottom pressing flap are bent inward of the carton, and the top / bottom pressing flap is cylindrical inside the carton. Pressing the top and bottom of the article placed at both open ends of the structure, and the top / bottom engaging fixings engage the recesses at the top and bottom of the article placed at both open ends of the tubular structure And the second top pressing flap and the second pressing flap formed by punching out a part of the top wall panel and the bottom wall panel are foldably connected via a fold line, Two top / bottom pressing flaps are folded inward of the carton, and are characterized by pressing and fixing the top and bottom of articles placed between the articles placed at both open ends.

  In the carton of the present invention configured as described above, the top / bottom pressing flaps press the top and bottom of the articles arranged at both open ends of the cylindrical structure in the article row, and the top / bottom engaging fixing part Is engaged with the recesses at the top and bottom of the article disposed at both opening ends of the cylindrical structure, and the article disposed between the articles disposed at both opening ends is also fixed. Since the top part and the bottom part are fixed by folding the second top part / bottom part pressing flap, all of these individual articles are firmly fixed, and can be prevented from falling off. In addition, since all the fixing means are formed by punching a part of the top wall panel and the bottom wall panel, and no additional panels are required, the amount of raw material used for the carton blank can be reduced. And cost reduction is possible.

  The present invention also includes a fold line connecting the top pressing flap, the top wall panel and the top engaging fixing portion, and a fold line connecting the bottom pressing flap, the bottom wall panel and the top engaging fixing portion, An arc shape is preferable. According to such a form, when the top / bottom pressing flap is folded inwardly into the carton, the folding line to be folded is arcuate, so that the top / bottom pressing flap is bent in an arcuate shape and the strength against external force is increased. To increase. As a result, the pressing of the top / bottom pressing flap against the article is strengthened and the engagement of the top / bottom engagement fixing part with the article is also strengthened.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, a carton and a carton blank for storing articles such as cans in 3 × 2 rows are illustrated, but the present invention is not limited to the carton and carton blank in the form described below.

  FIG. 1 shows a blank 1a for forming a carton for accommodating articles, which is made of cardboard or a similar foldable sheet material. In FIG. 1, a blank 1a includes a first bottom wall panel 10a, a first side wall panel 11a, a top wall panel 12, a second side wall panel 11b, and a second bottom wall panel 10b, which are crease lines. 20a, 22a, 22b and 20b are continuously connected so as to be bendable. By bending these panels and connecting the first bottom wall panel 10a and the second bottom wall panel 10b, a cylindrical structure for accommodating articles is formed.

  The top wall panel 12 is formed with four top pressing flaps 40 and top engaging and fixing portions 41 near the cylindrical structure opening end of the top wall panel by punching a carton blank. The top pressing flap 40 is connected to the top wall panel 12 and the top engagement fixing portion 41 via the crease line 30, and the top engagement fixing portion 41 is connected to the top wall panel 12 via the crease line 31. ing. Further, a second top pressing panel 42 is punched and formed at the center of the top wall panel 12 and connected via a crease line 32. Further, a pair of gripping flaps 43 are connected to the top wall panel 12 via crease lines 33. By folding the gripping flap 43 into the carton, the user can insert a finger into the carton and grip it.

  Similarly, in the first bottom wall panel 10a and the second bottom wall panel 10b, the bottom pressing flaps 44a and 44b and the bottom engagement fixing portions 45a and 45b are formed at the cylindrical structure opening end of the bottom wall panel by punching a carton blank. It is formed in four nearby places. The bottom pressing flap 44a is connected to the first bottom wall panel 10a and the bottom engagement fixing portion 45a via a fold line 34a, and the bottom engagement fixing portion 45a is connected to the first bottom wall panel via a fold line 35a. 10a. The bottom pressing flap 44b is connected to the second bottom wall panel 10b and the bottom engagement fixing portion 45b via a fold line 34b, and the bottom engagement fixing portion 45b is connected to the second bottom via a fold line 35b. It is connected to the wall panel 10b. In addition, second bottom pressing panels 46a and 46b are stamped and formed at the center of the first / second bottom wall panels 10a and 10b and connected via crease lines 36a and 36b. Furthermore, a lock flap 47 is formed in the second bottom wall panel 10b, and a lock flap receiving slit 50 is formed in the first low wall panel 10a. During the assembly of the carton, the first bottom wall panel 10a, the first side wall panel 11a, the top wall panel 12, the second side wall panel 11b, and the second bottom wall are inserted by inserting the lock flap 47 into the lock flap receiving slit 50. A cylindrical structure composed of the panel 10b is formed.

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

  First, after assembling, the blank 1a is placed horizontally so that the inner surface of the carton is upward and the outer surface of the carton is downward. Next, by bending the crease lines 30 and 31, the four top pressing flaps 40 and the top engaging fixing portions 41 are bent inward (upward) in the carton, and the top pressing flap 40 is brought into contact with the top wall panel 12. Then, four articles such as cans are placed on these flaps with the top part facing down. In addition, two top pressing flaps 42 are folded inwardly into the carton, and two articles are placed on these flaps with the top facing down while being in contact with the top wall panel 12. Subsequently, the first side wall panel 11a and the second side wall panel 11b are bent upward through the crease lines 22a and 22b and are brought into close contact with the side surface of the article, and the first bottom wall panel 10a and the second side wall panel 10a through the crease lines 20a and 20b. The bottom wall panel 10b is bent downward. At this time, the bottom pressing flaps 44a and 44b, the bottom engaging fixing portions 45a and 45b, and the bottom pressing flaps 46a and 46b are bent inwardly of the carton, and the respective flaps are formed on the first bottom wall panel 10a and the second bottom wall panel 10b. The first bottom wall panel 10a and the second bottom wall panel 10b are brought into close contact with the article while being in close contact, and at the same time, the lock flap 47 is inserted into the lock flap receiving slit 50 to close the cylindrical structure of the carton. Thus, a package as shown in FIGS. 3 and 4 is completed. FIG. 3 is a perspective view of a carton containing articles (cans such as beverages) as seen from above, and FIG. 4 is a perspective view as seen from below.

  In the carton of this embodiment, as shown in FIG. 3, the top engaging and fixing portion 41 is folded inward with the top pressing flap 40, so that the top pressing flap 40 does not adhere to the top wall panel 12. A gap is created between the top pressing flap 40 and the top wall panel 12, thereby pressing the top pressing flap 40 against the can C and the top pressing flap 40 engages the end of the can C. Furthermore, since the top engaging and fixing portion 41 folded inward of the carton is also engaged with the end portion of the can C, the can C can be prevented from falling off. In this way, the four cans arranged at the open end of the cylindrical structure of the carton are firmly fixed. Further, in the present invention, since the second top pressing panel 42 is folded inward of the carton, the second top pressing panel presses the can C inside the carton with a restoring force to return the carton to the outside. Engage with the end of C and fix. As described above, according to the present invention, not only the can disposed at the opening end, but also the can retained inside can be fixed, and dropping of all retained cans can be prevented. Further, at the bottom of the carton, as in the case of the top, the bottom pressing flap 44, the bottom engagement fixing portion 45, and the second bottom pressing flap 46 fix the bottom of the can C as shown in FIG. .

  In the present invention, an additional panel is not required to obtain the above-described effect, and the article is fixed only by the pressing flap and the engagement fixing portion formed by punching the top wall panel 12 and the bottom wall panels 10a and 10b. Since it is realized, the shape of the carton blank is a simple rectangular shape, and there is almost no waste part of the carton material at the time of manufacturing the carton blank, and cost reduction can be realized.

  A carton blank 1b according to another embodiment of the present invention is shown in FIG. The basic structure of the carton blank 1b is the same as that of the carton blank 1a, but the crease line 30 that divides the top pressing flap and the fold lines 34a and 34b that divide the bottom pressing flaps 44a and 44b are arcuate. This is the difference from the carton blank 1a. Thus, since the crease lines 30, 34a and 34b are arcuate, the top pressing flaps 40, 44a and 44b bend in an arcuate shape when folded inwardly into the carton. Compared to the case where the top pressing flap bent in an arc shape is flat, the bending strength of the flap itself with respect to an external force is improved, and the fold line itself is also in an arc shape so that the flap can be pushed back to the outside of the carton. The action to oppose is improved. As a result, the top pressing flap more firmly secures the article and prevents it from falling off.

  The specific embodiments of the present invention have been described above. However, the present invention is not limited to these embodiments. For example, the present invention is applicable to articles arranged in one row or cartons holding articles arranged in three or more rows. It is also possible to do.

  As described above, in the present invention, the first bottom wall panel and the second bottom wall panel are closed by the engagement of the lock flap and the slide lock flap receiving slit, but the present invention is not limited to these, Any closing means such as gluing can be taken.

  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, a carton and a carton blank can be provided.

It is a top view which shows the carton blank of this invention. It is a top view of the carton blank in other embodiments of the present invention. It is a perspective view of the carton top part which assembled the carton blank of FIG. It is a perspective view of the carton bottom part which assembled the carton blank of FIG.
