Description

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.

[0002]

2. Description of the Related Art Wrap films for wrapping foods are usually rolled into a paper cylinder and stored in a paper carton. This kind of carton makes it easy to pull out and cut the wrap film. In order to achieve this, a metal lid cutter is widely used at the edge of a cover lid piece that is continuously provided at the tip of the lid body. A carton of this type is known in which the edge of the cover lid and the tip of the cutter are V-shaped to prevent wrinkles when the wrap film is cut (see, for example, Japanese Patent Laid-Open Publication No. Sho. 63-27
2656 and JP-A-2-45349).

[0003]

The carton for the wrap film mentioned in the prior art can cleanly cut the wrap film, but since it uses a metal cutter, it is incinerated when it is discarded. Then, there was a problem that only the cutter part burns and causes pollution problems. In order to avoid this problem, the cutter has recently been removed at the time of disposal, but the work of removing the elongated metal cutter over the length direction is troublesome and at the same time there is a risk of injury.

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

[0005]

In order to achieve the above object, the present invention allows a lid to be undulated on one side edge of an upper opening of a carton body in which a roll-wrapped wrap film is stored. In a wrap film carton in which a lid lid piece that is continuously provided and overlaps with a front side surface of the carton body is provided at a tip end of the lid body, the edge of the lid lid piece has a V-shaped gently sloping shape. A small metal notch member is attached to the V-shaped tip of the covering lid piece, and a cutter made of a hard paper material along the edge of the covering lid piece other than the portion where the notching member is attached. It is characterized by being attached.

In order to facilitate the removal of the cutting member, it is preferable that a perforation be formed at the boundary between the cutting member and the cutter near the tip of the covering piece.

[0007]

In the carton for wrap film having the above structure, 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 lid piece, and then the wrap film is pulled straight or forward. Be done. Then, a notch is formed in the width center part of the wrap film by the notch member, and the notch is pulled as it is so that the notch extends to both ends of the film along the cutter at the edge of the cover lid edge and is cut neatly. Then, when the carton is discarded after use, the tip portion of the covering lid piece including the metal cutting member is broken and removed.

1 is a perspective view showing a carton for a wrap film according to an embodiment of the present invention before opening, and FIG. 2 is a perspective view showing the same after opening.

The carton C for wrapping film has the appearance of a rectangular parallelepiped box formed of paperboard, and a lid 3 is movably connected to one side edge of the upper opening 2 of the carton main body 1, At the tip of the lid body 3, there is provided a covering lid piece 4 and an unsealing piece 6 connected to the covering lid piece 4 by a cut line 5. In the state before the carton C is opened, the back surface of the unsealing piece 6 and the front side surface 7 of the carton body 1 are glued together at several spots.

A wrap film wound in a roll on a paper cylinder is stored in the carton body 1. This wrap film is, for example, a vinylidene chloride-based, vinyl chloride-based, or butadiene-based synthetic resin film.

A cutting line 5 which is a boundary between the covering lid piece 4 and the unsealing piece 6 is formed in a V shape which is gently inclined downward. Then, a metal notch member 8 shown in FIG. 3 is attached to the back side of the V-shaped tip of the covering piece 4 so that a sharpened portion 8a thereof projects to the back side of the unsealing piece 6, and further, the notch member A cutter 9 made of a hard paper material is attached along the edge of the covering lid piece 4 other than the portion to which 8 is attached so that the cutting edge portion 9a thereof projects to the back side of the unsealing piece 6. Therefore, when the unsealing piece 6 is peeled from the front side surface 7 and separated from the covering lid piece 4 along the cutting line 5, the end edge 4a of the covering lid piece 4 becomes a V-shaped gently sloping shape, and as shown in FIG. As shown, the cutting edge portion 9a of the cutter 9 projects from the edge 4a, and the sharpened portion 8a of the cutting member 8 projects from the V-shaped tip. In addition, after removing the opening piece 6,
The lid 3 together with the covering piece 4 can be opened and closed with respect to the opening 2 of the carton body 1.

The cutting member 8 is attached to the back side of the front end of the covering lid piece 4 by being crimped by the leg portions 8b and 8c on the left and right sides thereof. Further, the cutter 9 is formed by punching out a hard paper material, and as shown in FIG. 4, is attached to the rear side of the edge of the covering lid piece 4 with an adhesive in a state of being adjacent to both sides of the cutting member 8. There is. As the material of the cutter 9, paperboard impregnated with a curing agent, parchment paper, vulcanized fiber, thick tracing paper, or the like can be used.

When the wrap film is taken out after opening the carton C having the above construction, first, the carton body 1 is held by one hand and the wrap film is pulled out by the other hand. Then, the wrap film is sandwiched between the covering lid piece 4 and the front side surface 7 of the carton body 1 with one hand, and the other end of the wrap film is pulled horizontally or toward the front. By doing so, a notch is formed in the width center part of the wrap film by the sharpened portion 8a of the notch member 8, and the notch is pulled along with the film along the blade edge part 9a of the cutter 9 protruding from the end edge 4a of the covering lid piece. Of the wrap film, resulting in a clean cut of the wrap film. Then, if the wrap film after cutting held by the other hand is unloaded onto the food, tray, etc. as it is, as in the case of the conventional carton for wrap film, the wrap film remains in a substantially horizontal state. It is possible to wrap an item to be packaged.

Here, in the above embodiment, the shape of the sharpened portion 8a of the cutting member 8 is such that the cutting edge in the middle is high. For this reason, during the cutting operation, the cutting edge is easily formed in the central portion of the wrap film by the cutting edge in the middle, and the cutting line is extended with the notch in the central portion as an opportunity to extend the wrap. The film can be cut with a light force. In addition, even if the cutting member 8 provided with only one center cutting edge is used, it does not interfere with the cutting operation of the wrap film. The cut member 8 may be attached by eyelets or by a strong adhesive.

When the carton C having the above-mentioned structure is disposed of after use, the leading end portion of the covering lid piece 4 including the cutting member 8 is broken and removed, and the metal cutting member 8 can be disposed in a separated state. .. In order to facilitate this sorting operation, as shown in FIG.
Perforations 10 may be formed at the boundary between the cutting member 8 and the cutter 9 in the vicinity of the tip of the perforation, and the perforations 10 may be broken as a clue.

[0016]

As described above, in the carton for wrap film of the present invention, a small metal notching member is attached to the V-shaped tip of the covering lid piece, and the covering lid piece other than the portion to which the cutting member is attached is attached. Since a cutter made of hard paper material is attached along the edge, while maintaining the function of cutting the wrap film neatly, after use, only the area containing the metal notch member is removed and the paper is cut. It has the advantage that it can be discarded as part of only, thus avoiding pollution problems.

Further, since it is only necessary to break and remove the region including the small metal notch member at the time of separation, the separation operation can be performed easily as compared with the conventional case of removing a long metal cutter. it can.
