2. Description of the Related Art FIG. 6 is a perspective view showing a conventional wrap film storage case. This conventional example is, for example, Jikho Sho 61-2.
It is of the same type as that disclosed in Japanese Patent No. 2823.
In FIG. 6, reference numeral 1 is a case body made of cardboard, and includes a bottom plate 1a, both end plates 1b and 1c, and a front plate 1.
It is a rectangular parallelepiped box having d and a back plate 1e. A lid plate 2 is integrally extended to an upper edge portion of the back plate 1e of the case body 1, and a boundary portion between the back plate 1e and the lid plate 2 is a hinge portion 2a having a crease. A cover lid piece 3 is integrally extended at the tip of the lid plate 2, and a cutting member 4 having a saw blade is provided at the tip thereof. The film roll 5 having the core wrapped with the wrap film W is housed in the case body 1. The wrap film W is guided from the upper opening 1f of the case main body 1 between the front side plate 1d and the covering lid piece 3 and pulled out to the outside. After the wrap film W is drawn to a desired length, the case body 1 and the drawn wrap film W are twisted relative to each other, and the wrap film W is cut by the saw blade of the cutting member 4. At the center of the outer surface of the front plate 1d and at the portion where the covering lid piece 3 is overlapped, an adhesive material 6 is provided as a film retaining portion, and the cut wrap film W is fed from the outside of the covering lid piece 3 with fingers. Press with and adhesive material 6
By pressing it against, the detent to the film roll 5 in the case body 1 is stopped.

[0003]

In the conventional wrap film storage case shown in FIG. 6, the adhesive material 6 of the film retaining portion provided on the front surface of the front side plate 1d is a recess formed on the front side of the front side plate 1d. It is provided inside. Therefore, after pulling out the wrap film W and cutting it with the cutting member 4, even if the central portion of the covering lid piece 3 is pressed with a finger to press the cut wrap film W remaining in front of the front side plate 1d against the adhesive material 6, It is difficult to reliably press the film W against the adhesive material 6. Therefore, the wrap film remaining after the film is cut may be securely adhered by the adhesive material 6 and may not be held. In such a case, the wrap film W remaining in front of the front side plate 1d after cutting is the case body 1
It is easily rewound on the inner film roll 5. Therefore, when the adhesive material 6 is provided in the concave portion of the front side plate 1d as shown in FIG. 6, it is necessary to use a material having a strong adhesive force as the adhesive material 6. However, when the adhesive material 6 having a strong adhesive force is used, when the wrap film W is adhered to almost the entire surface of the adhesive material 6, the force for holding the wrap film W becomes too strong, and
When it is tried to separate the adhesive material 6 from the adhesive material 6, it may tear. As a conventional example other than the one shown in FIG. 6, there is one in which an adhesive material is provided as a film retaining portion without providing a concave portion on the front surface of the front side plate 1d, but also in this case, an adhesive material having a weak adhesive force is used. Then, when the force of pushing the cover lid piece 3 with a finger is weak, the wrap film W is not reliably adhered to the adhesive material 6,
If the adhesive strength of the adhesive material is too strong, the wrap film W
A similar problem arises, in which is retained by excessive adhesion. The present invention is to solve the above-mentioned conventional problems, and even if a film retaining portion having a relatively weak adhesive force is used, the wrap film remaining in front of the front side plate after cutting is cut with a finger through the covering piece. It is an object of the present invention to provide a wrap film storage case capable of reliably holding the wrap film in the film portion when pushed.

[0004]

A storage case for a wrap film according to the present invention is a box-shaped case body in which a bottom plate, a front plate, a back plate and two end plates are surrounded on five sides and one side is an opening. And a cover plate that is continuous with the back plate of the case body and can cover the opening, and a cover piece that is continuous with the tip of the cover plate and that is stacked in front of the front plate when the cover plate covers the opening. And a cutting member for cutting the film drawn out from between the front side plate and the cover lid, which is pulled out from the film roll housed in the main body case,
In the part of the front side plate covered by the cover lid , other parts of the front side plate
Protrusion that is formed by applying pressure to the lid lid side rather than the part
Is provided, and a film retaining portion that adheres and holds the drawn film is provided on the surface of the raised portion.
It is characterized by that.

[0005]

In the above-mentioned means, the wrap film is pulled out from the film roll and led out between the front side plate and the covering lid piece, after being cut by the cutting member, the covering lid piece is pressed with a finger to remove the wrap film remaining in front of the front side plate. Press on the film holding part. The front surface of the front side plate where the film holding section is provided projects more outward than the front surface of the other front side plates, so the wrap film can be pressed firmly against the film holding section by simply pressing the cover lid piece lightly. . Therefore, even if a film retaining portion having a weak adhesive force is used, the wrap film can be reliably retained in front of the front side plate. In this way, since the wrap film can be reliably pressed against the film retaining portion provided on the front surface of the front side plate, it is not necessary to use a film retaining portion that exhibits excessive adhesive force, and thus excessive adhesiveness The force causes the wrap film to stick and does not break when the wrap film is peeled off.

3 is an enlarged cross-sectional view of the wrap film storage case shown in FIG. The wrap film storage case shown in FIG. 1 is made of thick paper. The case body 10 is composed of a bottom plate 11, a front plate 12, a back plate 13, and two end plates 14 that connect the bottom plate 11, the front plate 12, and the both end portions of the back plate 13 to each other. It is a cubic box in which five surfaces are covered and the upper one surface is the opening 15. A cover plate 17 extends continuously from the upper edge of the back plate 13 of the case body 10. A boundary portion between the back plate 13 and the lid plate 17 is a hinge portion 16 formed by folding a cardboard as a material. Further, a cover piece 18 is bent at a right angle to the front edge of the cover plate 17 and extends integrally. The left and right end portions of the cover plate 17 and the left and right end portions of the covering lid piece 18 are connected by a side lid piece 19. When the lid plate 17 and the cover lid piece 18 are closed by the case body 10, the side lid piece 19 is placed on the outside of the end plate 14.

A lower edge portion 18a of the cover lid piece 18 is substantially V-shaped, and a cutting member 20 having a saw blade is attached along the lower edge portion 18a. As shown in FIG. 5, the cutting member 20 is attached to the lower part of the inner surface of the covering lid piece 18 with the saw blade facing downward. When the lid plate 17 is closed at the substantially left-right center position on the front surface of the front side plate 12, the cover lid piece 1
A film holding portion 21 is provided in a portion covered by 8. As shown in an enlarged scale in FIG. 2, the film retaining portion 21 has an adhesive portion 21a composed of a film whose surface is a layer of an adhesive material and which has an adhesive layer to the front surface of the front side plate 12 on the back surface, and its surface. Resin layer 2 that covers
1b and. The layer of the adhesive material on the surface of the adhesive portion 21a has a relatively weak adhesive force. Further, by providing the resin layer 21b on the surface,
The adhesive area on the surface of the adhesive portion 21a is adjusted to an appropriate width to prevent the drawn wrap film W from being stopped by an excessive adhesive force.

As shown in FIG. 2, a portion of the front surface of the front side plate 12 where the film holding portion 21 is provided and a peripheral portion thereof are formed with a raised portion 12a which is formed to project to the outside of the case body 10. Has become. The raised portion 12a projects slightly outward from the other portion of the front surface of the front plate 12. 3 and 4 show the boundary portion of the raised portion 12a by an enlarged cross-sectional view, the protrusion of the raised portion 12a is performed by press working using a mold (so-called embossing), but the front surface of the raised portion 12a is not shown. The amount of protrusion of is small. Further, as shown in FIG. 2, a reinforcing piece 12b is continuously formed at the upper edge of the front side plate 12, and this is the front side plate 1.
It is adhered to almost the entire back surface of No. 2 to reinforce the portion where the film retaining portion 21 is formed. The wrap film W is a core wound in a cylindrical shape, and the wound film roll 5 is housed in a case body 10. The wrap film W is, for example, a vinylidene chloride-based, vinyl chloride-based, polyethylene-based, polypropylene-based, or butadiene-based synthetic resin film.

Next, a method of using the wrap film storage case will be described. As shown in FIG. 5, the wrap film W pulled out from the film roll 5 in the case body 10 is fed from the opening 15 of the case body 10 to the front side plate 12.
It is guided to the outside through a space between the cover and the cover piece 18. When the wrap film W having a desired length is drawn out, the wrap film W is spread in a substantially horizontal state on an object to be packaged such as a tray. Then, with one hand, the cover plate 17 or the cover piece 18
5, the lid plate 17 covers the opening 15 and the covering lid piece 18 overlaps the front of the front side plate 12 as shown in FIG. With the other hand, pull the wrap film W horizontally and twist the case a little in the α direction (see FIG. 5). As a result, the saw blade of the V-shaped cutting member 20 cuts the central portion of the wrap film W, which creates a trigger for cutting. If you pull the wrap film W horizontally as it is,
The wrap film W is cut into a substantially V shape along the V-shaped saw blades.

After the cutting work is completed, the central portion of the covering lid piece 18 is pushed toward the front side plate 12 with a finger. The wrap film W cut by this and left in front of the front side plate 12 is adhered to and retained by the adhesive portion 21 a of the film holding portion 21. At this time, as shown in FIGS. 2 and 5, the raised portion 12a of the front side plate 12 in which the film holding portion 21 is provided.
Since it projects in the direction of the cover lid piece 18, the wrap film W can be reliably pressed against the film holding portion 21 by simply pressing the cover lid piece 18 lightly with a finger. Therefore, an adhesive material having a relatively weak adhesive force is used, and the wrap film W is reliably held with an appropriate adhesive force by the adhesive portion 21a which is covered with the resin layer 21b and has the smallest area. In the illustrated embodiment, the film retaining portion 21 using the adhesive portion 21a provided with the resin layer 21b on the surface is used, but an adhesive material not covered by the resin layer should be used as the film retaining portion. Is also possible. In addition, a plurality of film retaining portions may be formed on the front surface of the front side plate, and a raised portion may be formed on the front side plate 12 at a portion where each film retaining portion is provided.

[0011]

[Effect of the Invention] As described above, according to the present invention,
By forming a ridge protruding in the direction on the front side plate,
Since the film reserving portion is provided on the surface , the wrap film can be reliably retained in the film reserving portion only by lightly pressing the wrap film cut and left by the covering piece. In addition, the ridge is formed by pressing the front plate.
Since it can be formed, the manufacturing process of this ridge is easy.
It is simple. Also, the ridges formed by pressure molding are
The protrusion size is moderate, and it projects extremely large in the direction of the cover piece.
It doesn't matter. Therefore, when the lid plate is closed, the front plate
Forming an unnecessarily large gap between the cover and the lid piece
There is no need to improve the tightness of the storage case.
