Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a carton for a wrap film which accommodates a wrap film wound in a cylindrical shape and has a paper cutting blade for cutting the wrap film.

[0002]

[Prior Art]

 As shown in FIGS. 9 and 10, a wrap film carton that has been already proposed has a metal cutting blade 1 for cutting the wrap film between the bottom plate 2 and the auxiliary plate 3 of the wrap film carton. It is known that the structure is attached along the curve 4.

[0003]

[Problems to be solved by the device]

 However, in such a conventional structure, there are problems that a child is injured by the metal cutting blade 1 and that the metal cutting blade 1 cannot be incinerated at the time of disposal, and further, the assembling at the time of manufacturing. There were various problems that the work was troublesome and the cost was high. Then, in view of such a problem, a carton having a paper cutting blade has been proposed (for example, Japanese Utility Model Publication No. 56-3823, Japanese Utility Model Publication No. 53-157036, and Japanese Utility Model Publication No. 62-13830). Official Gazette, Japanese Utility Model Publication No. 56-13218, and Japanese Utility Model Publication No. 60-37295). However, in the above-mentioned conventional example, there is a problem in the position of the cutting blade in any configuration, such as the cutting blade being provided at the end of the carton flap, and the flap bends when the wrap film is cut. It had the drawback of being difficult to cut.

The object of the present invention was made in view of the above-mentioned drawbacks, and there is provided a carton for a wrap film, which can easily and surely cut the wrap film without causing the carton flap to bend when the wrap film is cut. To provide.

[0005]

[Means for Solving the Problems]

 According to a first aspect of the present invention, in a carton for a wrap film formed from one cardboard, an auxiliary plate is continuously provided adjacent to the bottom plate at a position overlapping the back side of the front plate at the time of box making, and the bottom plate is connected. It is characterized in that a sawtooth-shaped punched-out portion is provided on the boundary line between the auxiliary plate and the auxiliary plate, leaving a part of the connecting portion.

The invention of claim 2 is characterized in that a folding plate is further provided at a free end of the auxiliary plate, and the folding plate is folded on the auxiliary plate to form a double structure.

[0007]

[Action]

 Thus, according to the present invention, since the cutting blade is provided between the bottom plate and the auxiliary plate and is not located at the end of the carton flap, the flap does not bend when the wrap film is cut. The wrapping film can now be easily and reliably cut.

[0008]

【Example】

 Hereinafter, the details of the present invention will be described with reference to the embodiments shown in the drawings.

FIG. 1 is a developed plan view showing an embodiment of a wrap film carton according to the present invention, FIG. 2 is an assembled perspective view of the wrap film carton, and FIG. 3 is a sectional view of the wrap film carton. . As is apparent from FIG. 1, a rear plate 6, a cover plate 7, a front plate 8 and a flap 9 are sequentially arranged on the right side of the bottom plate 1 through folding curves 2 to 5, and the bottom plate 1 An auxiliary plate 10 is connected to the left side of the. On the boundary line between the bottom plate 1 and the auxiliary plate 10, as shown in FIGS. 4 and 5, a sawtooth-shaped punching portion 11 forming a cutting blade is provided with a part of the connecting portion 12 left. There is. Side plates 13 and flaps 14 are connected to both ends of the bottom plate 1, and adhesive pieces 15 and 16 are connected to both ends of the back plate 6 and the auxiliary plate 10, respectively.

Next, the assembling of the wrap film carton configured as described above will be described. First, in the unfolded state shown in FIG. 1, with the bottom plate 1 facing downward, the back plate 6, the lid plate 7, the front plate 8 and the flap 9 are sequentially bent into a rectangular tube shape as shown in FIGS. In this assembled state (during box-making), as shown in FIG. 3, the auxiliary plate 10 is provided at a position overlapping the back side of the front plate 8 and the cutting blade (saw tooth-shaped punch) at the time of distribution. In order to prevent tooth spillage of the removed portion 11), the flap 9 is bent so as to overlap with the lower side of the bottom plate 1.

As described above, according to the carton for wrap film of the present embodiment, the cutting blade is provided between the bottom plate 1 and the auxiliary plate 10, so that the auxiliary plate 10 can be manually operated when the box is used. The bottom plate 1 provided with a cutting blade does not bend inward as a support when held, and since the bottom plate 1 and the auxiliary plate 10 are partially connected via the connecting portion 12, the wrap film The bottom plate 1 does not bend outward during cutting.

6 to 8 are views showing another embodiment of the wrap film carton according to the present invention. In this embodiment, the configurations of the bottom plate 1, the back plate 6, the lid plate 7, the front plate 8, the flaps 9, the auxiliary plate 10, the side plates 13, the flaps 14, and the adhesive pieces 15 and 16 are the same as those in the first embodiment. On the boundary line between the bottom plate 1 and the auxiliary plate 10, in the same manner as in the first embodiment, the saw-tooth-shaped punched-out portion 11 constituting the cutting blade is partially connected (not shown). It is provided. This embodiment is different from the above-mentioned embodiment in that the folding plate 19 and the adhesive piece 20 are further attached to the free end of the auxiliary plate 10, that is, the left end portion of the auxiliary plate 10 in FIG. This is an added configuration. In this structure, at the time of assembly (during box making), the folding plate 19 is positioned on the back side of the auxiliary plate 10 in a folded state to form a double wall, and the folding plate 19 is bonded via the adhesive piece 20. The structure is adhesively fixed to the bottom plate 1.

In this way, if the folding plate 19 is further provided at the free end of the auxiliary plate 10 and is folded over the auxiliary plate 10 to form a double structure, the bottom plate 1 provided with the cutting blade is reinforced and bends. It makes it easier to cut the wrap film.

[0014]

[Effect of the device]

 As described above, according to the carton for wrap film of the present invention, the auxiliary plate is continuously provided adjacent to the bottom plate at a position overlapping the back side of the front plate during box making, and the boundary between the bottom plate and the auxiliary plate is formed. The sawtooth-shaped punching part is provided on the line with a part of the connecting part left, so that the cutting blade is located between the bottom plate and the auxiliary plate, and it is located at the end of the carton flap as before. Since it is not located, it is reliably prevented that the carton will bend when the wrap film is cut. As a result, there is an excellent effect that the wrap film can be cut more easily and surely than ever before. Further, if a folding plate is further provided at the free end of the auxiliary plate and the auxiliary plate is folded and formed into a double structure, the bottom plate provided with the cutting blade is reinforced so that it does not bend, thereby further The wrap film can be easily and surely cut.
