  A roll-shaped packaging material such as a wrap film used for wrapping food or the like is usually stored in a paper carton in a state of being rolled around a paper tube. Then, after a packaging material such as a wrap film is drawn out to a desired length from the carton, it is cut and used by a saw blade member such as metal attached to the carton. By the way, in the conventional carton of this type, the carton body is only covered with a lid, so that a roll-shaped packaging material such as a wrap film inside the lid may open and fall. Therefore, in order to prevent the roll-shaped packaging material from jumping out, many shapes are known in which tongue pieces are provided on the side plate of the carton body. (For example, refer to Japanese Utility Model Publication No. 7-12267).

  However, the roll-shaped packaging material storage carton having a tongue provided on the side plate of the carton body has a risk of intrusion of foreign matters from the outside, which is problematic in terms of hygiene. In order to solve this problem, various shapes have been studied. For example, various shapes have been proposed in which a pressing piece or the like is connected to the front plate to prevent the roll-shaped packaging material such as a wrap film from popping out. ing. However, even with this shape, the position of the presser piece is not stable and the effect of preventing the roll-shaped packaging material from popping out is uncertain, and there is a problem that it becomes difficult to pull out when pulling out wrap film etc. It is in a state of not having a satisfactory shape.

  The present invention has been made in view of the above-described problems, and an object thereof is a carton for storing a roll-shaped packaging material such as a wrap film, and the stored roll-shaped packaging material pops out. Another object of the present invention is to provide a roll-shaped packaging material storage carton having a structure that can be easily formed without causing any trouble in pulling out a roll-shaped packaging material such as a wrap film.

In order to achieve the above object, the roll-shaped packaging material storage carton of the present invention is connected in a undulating manner to one side edge of a carton body and its upper opening that stores a roll-shaped packaging material wrapped with a wrap film or the like. In a rolled packaging material storage carton having a box-shaped lid, a folded reinforcing plate is connected to the upper side of the main body front plate of the carton main body, and the folded reinforcing plate is folded inside the carton main body. A roll-shaped packaging material storage carton, characterized in that a part of the back surface of the carton body is raised, a part that is not bonded is raised, and a roll pressing portion protruding in the inner direction of the carton body is formed. on the back of the body front plate, bonded to both sides of the folded reinforcing plate, a cut or wedge on each side of the central portion which is not bonded in the folded reinforcing plate It is, causing the central portion of the folded reinforcing plate, characterized by comprising forming said roll pressing portion.

  The roll-shaped packaging material storage carton of the present invention having the above configuration is a carton for storing a roll-shaped packaging material shape such as a wrap film, and a folded reinforcing plate connected to the main body front plate of the carton main body is provided on the main body front plate. By partially sticking to the back side and raising the unbonded part to make the roll presser part protruding in the inner direction of the carton body, the stored roll-shaped packaging material is surely prevented from popping out and falling. In addition, the carton has a structure that can be easily formed without hindrance to pulling out a roll-shaped packaging material such as a wrap film.

  As described above, the roll-shaped packaging material storage carton of the present invention having the above-described configuration is a carton for storing a roll-shaped packaging material such as a wrap film, and is folded back and connected to the main body front plate of the carton body. A part of the plate is pasted on the back of the front plate of the main body, and the part that is not pasted is raised to form a roll presser that protrudes inward of the carton main body. This is advantageous in that it can be reliably prevented and can be easily formed into a shape that does not hinder the drawing of a roll-shaped packaging material such as a wrap film.

  FIG. 1 is a perspective view showing a reference example of a roll-shaped packaging material storage carton according to the present invention. The roll-shaped packaging material storage carton 1 stores a roll-shaped packaging material R obtained by winding a wrap film F around a paper tube. The carton body 10 and the lid 20 are constituted. Unlike a normal roll-shaped packaging material storage carton, a part of the folded reinforcing plate 17 folded back from the upper side of the main body front plate 11 of the carton main body 10 is bonded to the back surface of the main body front plate 11 and is not bonded. It is a feature that the part is raised to form a roll presser P protruding inside the carton main body 10 and to prevent the roll-shaped packaging material R stored in the carton main body 10 from popping out. When used in general households, stores, etc., the necessary length of the wrap film F is drawn from the roll-shaped packaging material storage carton 1 and is mainly used for packaging foods such as seafood, side dishes and fruits.

  FIG. 2 is a development view showing a blank of the roll-shaped packaging material storage carton 1 according to the present invention. Blank 1A is comprised from the part of the cover body 20 which covers the part of the carton main body 10 which accommodates the roll-shaped packaging material R, and the opening part of the carton main body 10. As shown in FIG. In the carton body 10, the main body front plate 11, the main body bottom plate 12, and the main body rear plate 13 are sequentially connected via the folding lines a and b, and the main body folding pieces 14 and 14 are bent on both sides of the main body front plate 11. The main body side plates 15 and 15 are connected to both side edges of the main body bottom plate 12 via fold lines d and d, respectively, and the main body folding edge is connected to both side edges of the main body rear plate 13. 16 and 16 are connected to each other via broken lines e and e.

  Further, a folded reinforcing plate 17 is connected to the upper side of the main body front plate 11 via a broken line f. The folded reinforcing plate 17 is folded inward from the upper side of the main body front plate 11 and is partially bonded to the back surface of the main body front plate 11. That is, a roll pressing portion P having a shape that sticks at a part and raises the remaining portion that is not bonded and protrudes inside the carton body 10.

  The method of bonding the folded reinforcing plate 17 to the back surface of the main body front plate 11 is divided into two methods depending on the portion to be bonded, and one of them is a central portion of the folded reinforcing plate 17 as shown in FIG. There is a method of pasting (halftone dot part), and another method is a method of pasting both side parts (halftone dot part) as shown in FIG. Therefore, in the former case, as shown in FIG. 3B, both sides are raised to form a roll presser P protruding inside the carton body 10, and in the latter case, as shown in FIG. A roll presser part P that is raised by protruding the part is used.

Further, in the former case, as shown in FIG. 3C, it is possible to make it easy to raise by providing a polygonal line h on both sides which are raised portions.

  Further, in the latter case, in order to easily raise the central portion, as shown in FIG. 4C, at both ends of the raised portion, as shown in FIG. It is preferable to make the shape into which. Furthermore, as shown to FIG. 4-d, it can also be set as the circular arc shape which expanded the edge | side of the center part. By setting it as this circular arc shape, it becomes difficult to pull out the wrap film F, and it is possible to prevent scratches and the like.

  In any case, the corner of the raised part needs to be rounded so as not to damage the wrap film F when it is pulled out.

  On the other hand, in the lid 20, the lid lid plate 21 is connected to the lower side of the main body rear plate 13 via a broken line i, and the lid front plate 22 is folded to the lower side of the lid lid plate 21. j are connected via j. Also, lid side plates 23 and 23 are connected to both sides of the lid plate 21 via fold lines k and k, respectively, and lid folding pieces 24 and 24 are placed on both sides of the lid front plate 22. They are connected via broken lines l and l, respectively. Further, a cutout portion 22a for separating the cutter body C to expose the cutter C at the time of use is defined by a broken line D, and the portion of the main body front plate 11 to which the cutout portion 22a is bonded is formed from the surface. A plurality of adhesion regions H formed by half cutting are formed. In this adhesion region H, the cut-out portion 22 a of the lid front plate 22 is bonded to the main body front plate 11.

  Next, a process of assembling the paperboard blank 1A having the above-described configuration to form the roll-shaped packaging material storage carton 1 of the present invention will be described. That is, in the same process as a general roll-shaped packaging material storage carton, a roll-shaped packaging material storage carton 1 that is folded by folding according to a fold line while being glued to a necessary portion of the blank 1A is produced, and then automatically filled and packaged A roll-shaped packaging material R of a wrap film F wound in a roll shape is accommodated in a roll-shaped packaging material storage carton 1 by a line.

  First, the folded reinforcing plate 17 is folded inward along the fold line f and bonded to the back surface of the main body front plate 11. At that time, in the case of the present embodiment, the bonding is performed on both sides. Next, the main body front plate 11 is folded inward along the fold line a, and then the lid body lid plate 21 is folded along the fold line i so that the lid body front plate 22 is superimposed on the main body front plate 11, and the lid body front plate 22 is cut off. The folded packaging material storage carton 1 is produced by pasting the portion 22a and the main body front plate 11 together. In such a folded state, storage, transportation, and the like before filling the roll-shaped packaging material R of the contents are performed.

  Next, the roll-shaped packaging material R in which the wrap film F or the like of the contents is wound is stored in the roll-shaped packaging material storage carton 1 in the automatic filling and packaging line. The roll-shaped packaging material storage carton 1 in a folded state is raised to form a quadrangular prism shape, and the roll-shaped packaging material R is inserted from the opening on one side surface. After inserting the roll-shaped packaging material R, the main body folding pieces 14 and 16 are bent, and the main body side plate 15 is bent thereon, and the main body folding pieces 14 and 16 and the side plate 15 are bonded together. Next, one side surface is formed by folding the lid folding piece 24 and folding and bonding the lid side plate 23 thereon. Similarly, the other side surface is formed to complete the roll-shaped packaging material storage carton 1.

  Actually, in order to use the roll-shaped packaging material storage carton 1 of the present invention, after removing the cut portion 22a of the lid front plate 22 along the breaking line D while removing it from the main body front plate 11, FIG. As shown in FIG. 5, the lid 20 is opened, and the unbonded portion of the central portion of the folded reinforcing plate 17 in which both side portions are bonded to the back surface of the main body front plate 11 is raised. It is set as the roll press part P of the shape which protruded in the inner side direction. After that state, the edge of the wrap film F is picked and pulled out by a desired length, and then cut with a cutter C. At this time, the roll pressing portion P has a shape protruding inward from the main body front plate 11, and the roll-shaped packaging material R can be prevented from jumping out.
