DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrap film carton for storing a wrap film used for food packaging and the like.

[0002]

2. Description of the Related Art A wrap film for wrapping food or the like is usually wound in a roll on a paper tube and stored in a paper carton. This kind of carton makes it easy to pull out and cut the wrap film. For this purpose, a cover with a metal cutter attached to the edge of a cover piece connected to the tip of the cover is widely used. A carton of this type is known in which the edge of the cover piece and the tip of the cutter are V-shaped so as not to wrinkle when the wrap film is cut (for example, see Japanese Unexamined Patent Publication No. 63-27
2656 and JP-A-2-45349).

[0003]

The wrap film carton described in the prior art can cut the wrap film neatly, but uses a metal cutter so that it is incinerated when disposed of. Then, there is a problem that only the cutter part burns and causes a pollution problem. In order to avoid this problem, the cutter has recently been removed at the time of disposal, but removing the long metal cutter in the longitudinal direction is troublesome and there is a risk of injury.

[0004] The present invention has been made in view of the above problems, and an object thereof is to provide a wrap film which is excellent in disposability while maintaining a function of cutting the wrap film neatly. To provide carton for

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to a carton body in which a wrap film wound in a roll is accommodated. In a wrap film carton, which is provided with a cover piece that is continuously provided at a tip end of the cover body and overlaps with a front side surface of the carton body, an edge of the cover piece is gently inclined in a V-shape. A cutter made of a hard paper material is attached along the V-shaped edge of the cover piece, and a small metal cutting member is attached to the V-shaped tip so as to overlap the cutter. The cover piece is formed with a break line defining a region including the cutter and the cutting member.

[0006]

In the carton for a wrap film having the above construction, the wrap film is pulled out from the carton body and is sandwiched between the front side surface of the carton body and the cover, and then the wrap film is pulled straight or pulled forward. Can be Then, a notch is formed at the center of the width of the wrap film by the sharp cutting member made of metal, and the cut is extended as it is to the both ends of the film along the cutter at one edge of the cover to be cut neatly. When the carton is discarded after use, the area including the cutter and the metal cutting member is removed from the cover piece.

[0007]

FIG. 1 is a perspective view showing a wrap film carton according to an embodiment of the present invention before opening, FIG. 2 is a perspective view showing the same after opening, and FIG. 3 is a sealed cover piece. FIG. 2 is a partially enlarged view of the vicinity of the tip of the camera viewed from the back side.

The wrapping film carton C has the appearance of a rectangular box made of paperboard, and a lid 3 is connected to one side edge of the upper opening 2 of the carton body 1 so as to be able to move up and down. A cover piece 4 and an opening piece 6 connected to the cover piece 4 by a cutting line 5 are provided at the tip of the cover 3. Then, before the carton C is opened, the back surface of the opening piece 6 and the front side surface 7 of the carton main body 1 are glued at several spots.

In the carton body 1, a wrap film wound in a roll around a paper cylinder is stored. The wrap film is, for example, a synthetic resin film of vinylidene chloride, vinyl chloride, butadiene or the like.

A cut line 5 which is a boundary between the cover piece 4 and the opening piece 6 is formed in a V-shape gently inclined downward. Then, a paper cutter 8 is attached along a cut line 5 serving as a V-shaped edge 4a of the cover piece 4 so that the cutting edge portion 8a protrudes to the back side of the opening piece 6. As shown in FIG. 3, a small metal cutting member 9 is attached to the tip of the V-shape so as to overlap with the cutter 8.
Therefore, the opening piece 6 is peeled from the front side face 7
When the cover 4 is separated from the cover 4 and removed, the edge 4a of the cover 4 is gently inclined in a V-shape, and as shown in FIG. Is projected, and the sharp portion 9a of the cutting member 9 projects from the V-shaped tip. Further, a break line 10 is formed on the cover piece 4 to divide a region including the cutter 8 and the cutting member 9. The break line 10 is formed of a half-cut rule line such as a perforation line or a lead rule, and serves as a guide when breaking by hand.

The cutter 8 may be made of paperboard impregnated with a hardener, parchment paper, vulcanized fiber,
It is made of a hard paper material such as thick tracing paper. Then, a sheet obtained by laminating a metal plate having a predetermined width on the paper material is punched into a saw blade shape by a punching machine to form a united cutter 8 and a cutting member 9. At the time of the board, the cutter 8 and the cutting member 9 are attached along the back surface of the edge 4a of the cover piece 4 by pasting with an adhesive along the cutting line 5 as described above. In this case, the cutter 8 is attached to the back surface of the cover piece 4 in such a direction that the cutting member 9 is exposed to the front side so that the metal surface of the cutting member 9 hits the wrap film when cutting the wrap film.

When the wrap film is taken out after opening the carton C having the above structure, first, the carton body 1 is held with one hand and the wrap film is pulled out with the other hand. Next, the wrap film is sandwiched between the cover piece 4 and the front side surface 7 of the carton body 1 with one hand, and the tip of the wrap film is pulled horizontally or forward with the other hand. In this way, a notch is formed at the center of the width of the wrap film by the sharpened portion 9a of the notching member 9, and the notch is pulled along with the film along the cutting edge portion 8a of the cutter 8 protruding from the edge 4a of the cover piece. And the wrap film is cut cleanly. Then, if the cut wrap film held by the other hand is dropped on a food or a tray as it is, the wrap film is kept substantially horizontally spread, as in the case of the conventional wrap film carton. It can wrap packages.

Here, in the above-described embodiment, the shape of the sharpened portion 9a of the cutting member 9 is set so that the middle cutting edge becomes higher. For this reason, at the time of the cutting operation, a notch is easily formed at the center portion of the wrap film by the middle blade, and the cut line is extended by the cut at the center portion, and the wrapping is performed. The film can be cut with a light force. In addition, even if the cutting member 9 is formed in a shape provided with only one middle blade edge, it does not interfere with the cutting operation of the wrap film.

When the carton C having the above structure is to be discarded after use, the area of the cover piece 4 including the cutting member 9 and the cutter 8 is broken off at the breaking line 10 and the metal cutting member 9 is separated. Can be discarded.

The breaking line 10 is not limited to the shape as shown in FIGS. 1 and 2, but may be provided anywhere as long as it has a shape capable of breaking and removing the area including the cutting member 9 and the cutter 8. Good thing.

Although it is preferable that the cutting member 9 and the cutter 8 are integrally formed as in the above embodiment, the cutting member 9 may be separately formed and attached in a separate step from the step of bonding the cutter 8. . In this case, the cutting member 9 is attached by caulking, eyelets or an adhesive. The mounting location may be on the front side or the back side of the cutter 8, but in the case of the back side, the metal cutting member 9 is used.
In order to take advantage of the sharpness of the blade, it is necessary that the sharp portion 9a of the cutting member 9 protrudes beyond the cutting edge of the cutter 8.

[0017]

As described above, the wrapping film carton of the present invention has a cutter made of a hard paper material attached along the V-shaped edge of the cover piece and a small metal piece attached to the V-shaped tip. Notch, and the cover piece has a break line that separates the area including the cutter and the notch, so while maintaining the function of cutting the wrap film neatly, the cutter can be used after use. And has the advantage that the area containing the metal cutting member can be removed and discarded, thus avoiding pollution problems.

Further, at the time of separation, it is only necessary to tear off the area including the cutter and the cutting member along the breaking line, and thus the separation operation can be easily performed as compared with the case of removing the conventional long metal cutter. be able to. In addition, since the metal cutting member is small, the risk of injury to the hand is extremely small as compared with the case where a long metal cutter is attached.
