Description

  The present invention relates to a carton that accommodates articles, and more particularly, to a carton that is easy to assemble and can significantly reduce raw material costs.

  2. Description of the Related Art Conventionally, cartons are provided that contain a plurality of articles and display them as merchandise in stores, and are used for distribution and consumer use. A product in which an article is stored in a carton is displayed, for example, in a display shelf of a store in a state where a plurality of products are suspended by passing a gripping portion of the carton through a hook. 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 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, having a front end and a rear end open, and capable of checking the contents. Are known. Further, many cartons are known, such as a carton having a partially closed structure (side wall panel) to prevent the articles from falling off at the opening of the round-up carton, and further, one end of the top wall panel of these cartons or A carton has been devised that has a gripping part panel on a part of the top wall panel and that can be folded and raised to form a gripping part that can be carried and displayed (for example, see Patent Document 1). .)

  However, the grip part formed only by bending such a panel has a problem in strength, and depending on the weight of the contents and how to handle the carton, the panel constituting the grip part and the panel constituting the carton body There is a problem that stress concentrates on the crease line forming the boundary of, and breaks.

  For such a problem, a gripping panel formed independently adjacent to the top wall panel is once folded inward in the carton and overlapped with the top wall panel, and further through the opening formed in the top wall panel, It is formed independently in the carton (for example, refer to patent documents 2 and 3) which makes the tip part of the gripping part panel project from one side to the outside to make the gripping part, and other parts not adjacent to the top wall panel of the carton blank. A carton is disclosed in which a grip portion is formed by projecting the grip portion panel from the inside of the carton through an opening formed in the top wall panel during assembly to the outside (see, for example, Patent Documents 4 and 5). ).

US Pat. No. 2,661,142 U.S. Pat. No. 2,168,387 U.S. Pat. No. 2,663,485 U.S. Pat. No. 2,191,723 U.S. Pat. No. 4,700,831

  According to these cartons, an independent gripping part panel is superimposed on the top wall panel from the inside of the carton, and a part thereof is projected outside the carton to form the gripping part. In this carton, the top wall part is doubled, and in the carton of Patent Document 2, the strength is remarkably improved compared to the conventional carton where the gripping part panel is folded to form the gripping part. ing.

  However, since these cartons have an independent gripping panel, the amount of cardboard or the like used as a raw material increases, and there is a problem of increased cost. Further, as in the carton blank described in Patent Document 2, since the grip part panel is formed in a shape that additionally protrudes from the carton blank main body, when the carton blank is punched from the raw cardboard, In addition, there is a problem that the waste portion around the grip portion panel is increased, resulting in waste of raw materials.

  This invention is made | formed in view of the said condition, and it aims at providing the carton which can maintain the intensity | strength of a top wall panel and a holding part, and can suppress raw material cost. .

  The present invention is a carton for holding an article, and includes a plurality of panels including a bottom wall panel, a pair of side wall panels, and a top wall panel for forming a cylindrical structure. A gripping flap formed by punching out a part of the panel and the top wall panel is foldably connected. The gripping flap includes a first portion that forms a tip portion and a second portion that is connected to the top wall panel. The wall panel includes a gripping flap through-opening, the gripping flap is bent inward of the carton, the top wall panel and the second part are brought into close contact with each other inside the carton, and then the gripping flap through-opening from the inside of the carton. And the first portion is projected outward from the carton.

  In the carton of the present invention having the above-described configuration, the gripping flap is once folded into the carton so that the second portion and the top wall panel are brought into close contact with each other. Since the load is supported by the entire overlapped surface, the stress is not concentrated in part, and the strength of the carton gripping portion is improved. In addition, since the grip flap is formed by punching when the window portion is formed on the side wall panel of the carton instead of additionally providing means such as a grip panel, the raw material cost can be suppressed.

  Furthermore, in the present invention, it is preferable that the gripping flaps are provided on each of the opposing side wall panels in a pair and project outward from the gripping flap through-opening portion in an overlapping state. According to such a form, since the area of the overlapping surface of the top wall panel that supports the load and the grip flap second portion is doubled, the strength is further improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited to the carton and carton blank of the form demonstrated below.
FIG. 1 shows a blank 1a for forming a carton for containing 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. 20 to 23 are continuously connected so as to be foldable. 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.

  Further, the third side wall panel 13a and the fourth side wall panel 13b can be bent along the crease lines 24 and 25 in a direction orthogonal to the direction in which the first side wall panel 11a and the second side wall panel 11b of the top wall panel 12 are connected. Connected continuously. Folding panels 15a and 15c are continuously connected to the side end portion of the first side wall panel 11a so as to be foldable by crease lines 28a and 28c. Folding panels 15b and 15d are connected to the side end portion of the second side wall panel 11b. Are continuously connected to each other by fold lines 28b and 28d. Furthermore, the connection panels 14a-14d are continuously connected to the end of the third side wall panel 13a and the end of the fourth side wall panel 13b so as to be foldable by the fold lines 26a-26d. These connection panels 14a-14d connect between the third side wall panel 13a and the folding panels 15a, 15b and between the fourth side wall panel 13b and the folding panels 15c, 15d. The third side wall panel 13a and the fourth side wall panel 13b are interlocked with each other as the carton is folded inward.

  On the top wall panel 12 and the first side wall panel 11a, a window part 50a and a gripping flap 30a + c are formed by cutting out a carton blank. Similarly, on the top wall panel 12 and the second side wall panel 11b, a window part 50b and a gripping part are formed. A flap 30b + d is formed. The gripping flap 30a + c includes a first portion 30a and a second portion 30c. The second portion 30c is continuously connected to the top wall panel by a fold line 29a so as to be foldable, and the first portion 30a is secondly connected by the fold line 29c. The portion 30c is continuously connected to bendable. The gripping flap 30b + d includes a first portion 30b and a second portion 30d. The second portion 30d is continuously connected to the top wall panel so as to be foldable by a fold line 29b, and the first portion 30b is foldable by a fold line 29d. The second portion 30d is continuously connected to be bent. The windows 50a and 50b are for confirming the contents held in the carton being displayed. The grip flap first portions 30a and 30b constitute a carton gripping means in the carton assembly process described later. In the conventional carton, as described above, an independent gripping panel is required to form the gripping means, and the carton blank raw material cost has been increased. Since the gripping flap is formed, the material cost can be suppressed. The top wall panel 12 is formed with a grip flap penetrating opening 40. The grip flap penetrating opening 40 is an opening for forming grip means by penetrating the grip flap first portions 30a and 30b outward of the carton. The gripping means is formed in the assembled state of the carton, and the user can grip the gripping means to facilitate carrying of the carton containing the article.

  A lock flap 31 is formed in the second bottom wall panel 10b, and a lock flap receiving slit 41 is formed in the first bottom 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 31 into the lock flap receiving slit 41. 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 surface that becomes the inner side of the carton is upward and the surface that becomes the outer side of the carton is downward. Next, the folding flap second parts 30c and 30d are folded upward (inside the assembled carton) along the crease lines 29a and 29b to bring the second parts 30c and 30d and the top wall panel 12 into close contact with each other. The grip flap first portions 30a and 30b are bent along 29c and 29d and inserted into the grip flap through-opening 40, and protruded below the blank (outside the carton after assembly). Subsequently, the first side wall panel 11a, the second side wall panel 11b, the third side wall panel 13a, and the fourth side wall panel 13b are folded upward along the crease lines 21, 22, 24, and 25, and at the same time, the crease lines 28a to 28d. The folding panels 15a to 15d are folded inward along the carton to bring the folding panels 15a to 15d into close contact with the first side wall panel 11a and the second side wall panel 11b. Finally, the contents are inserted into the carton upside down, the first bottom wall panel 10a and the second bottom wall panel 10b are folded along the fold lines 20 and 23 to close the carton, and the lock flap 31 is Insert the lock flap receiving slit 41 to secure the closure. Thus, the package as shown in FIG. 2 is completed (in the figure, the content article is omitted and only the carton is shown).

  In the carton of the present embodiment, as shown in FIG. 3, the gripping panel is folded inwardly of the carton so that the second portion and the top wall panel are brought into close contact with each other, and the first portion is further outward from the gripping panel through opening. Since the gripping means is formed by projecting, the gripping means supports the carton body when the gripping panel second portion folded inward and the top wall panel 12 come into close contact with each other. Thus, since the weight is supported by the whole panel surface which closely_contact | adhered, intensity | strength is maintained. Furthermore, since the grip panel is not formed of an additional panel portion with respect to the carton body, but is formed when an unnecessary portion is cut out when forming the window portion, an increase in raw material cost can be suppressed.

  In the present embodiment, the folded panel is folded and brought into intimate contact with the side wall panel, then the article is accommodated, and the contained article holds the folded panel in close contact with the side wall panel. The third and fourth side wall panels connected to the folding panel are also held closed. Thus, the closing of the side wall panel is supported by supporting the article without any other connection means such as gluing or engagement of flaps. However, the closing mechanism for the cylindrical structure opening of the present invention is not limited to this example, and any other connecting means can be used.

  In this embodiment, the carton bottom wall panel is closed by engaging the lock flap and the slide lock flap receiving slit. However, the present invention is not limited to these, and any closing means such as gluing can be used. 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. In addition, the present invention can 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, it is possible to provide a carton and a carton blank that can both maintain the strength of the gripping part and suppress the increase in raw material cost.

It is a top view which shows the carton blank in one Embodiment of this invention. It is a perspective view of the carton which assembled the carton blank of FIG. FIG. 3 is a cross-sectional view taken along line AA of the carton gripping part in FIG. 2.
