[Industrial applications]

 This invention stores a packaging web of plastic film, metal foil, etc. in the form of a roll, and when using it, pulls out the web and cuts it by the paper uneven blade provided on the container for the required length. It relates to a web container for packaging with a blade.

[0002]

[Prior art]

 Store the packaging web of plastic film, metal foil, etc. in a roll shape.When using the web, pull out the web and push only the required length against the paper uneven blade, which is a cutter installed in the container. Storage containers adapted to be cut by application are described in, for example, Japanese Utility Model Application Laid-Open No. 2-83229 and Japanese Patent Application Laid-Open No. 4-33975, and are well known.

[0003]

[Problems to be solved by the device]

 For these items, the conventional metal uneven blade is dangerous when handling, and when the container is discarded after using the web, the uneven blade must be removed from the container, sorted, and then discarded. For this reason, paper was used as the material for the uneven blade, and it was hardened by coating or impregnating it with a synthetic resin to supplement the hardness, but the above-mentioned difficulties were not solved. However, since the sharpness is not satisfactory, it is an object of the present invention to provide a storage container with a sharpness that can be sufficiently satisfied even with an uneven blade made of paper.

[0004]

[Means for Solving the Problems]

 In order to attain the above-mentioned problems, the present invention is a package with a paper uneven blade, in which a packaging web 2 wound in a roll is pulled out from a storage container body 1 and cut by a paper uneven blade 4 provided in the storage container body 1. In the container for storing webs, the paper concave-convex blade 4 is obtained by single-edged punching, and the method X of the punching and the paper concave-convex blade 4 of the packaging web 2 for cutting. The web container for wrapping with a paper-made concavo-convex blade is provided in the container body 1 so that the approach direction Y with respect to is aligned.

In the present invention, the paper concavo-convex blade 4 may be a paper obtained by coating or impregnating a paper with a thermosetting synthetic resin or an ultraviolet curable synthetic resin, and curing the synthetic resin. It may be made of hard paper that is not cured.

In this invention, the paper uneven blade 4 may be coated or impregnated with silicone oil or silicone resin. The coating or impregnation of the silicone oil or the silicone resin may be applied to the one cured by coating or impregnation of the synthetic resin for curing the paper.

According to the present invention, one storage container forming piece is bent and assembled to form the storage container main body 1. In the case where the storage container forming piece is formed, a concave-convex blade is formed on a part of the storage container forming piece by a single-edged cutting process. The concave and convex blades may be formed separately from the storage container forming piece in advance by a single-blade punching process and attached to the storage container main body 1. In any case, the concave and convex blades formed on the finished storage container should be such that the direction X of the punching process and the direction Y of entry of the packaging web 2 into the concave and convex paper 4 of paper coincide. Must have been done.

In this invention, the packaging web refers to a plastic film, a metal foil, or the like.

In the present invention, the single-edged punching is to obtain a concave-convex blade by pressing a concave-convex blade from one side to the material paper to obtain a concave-convex blade. Is the direction in which the uneven blade is pressed against the material paper.

In this invention, the concavo-convex blade has a sawtooth shape as shown in FIGS. 4 and 5, and a tooth shape different from the adjacent teeth 5 and 5'as shown in FIG. In addition to the shape in which the teeth 5 and 5'are repeatedly and regularly arranged, the shape in which different tooth shapes are irregularly arranged as shown in Figs. 7 and 8, and also in Figs. 4 to 7. Although the teeth have the same height, the teeth may have a shape in which teeth 5 and 5 ″ having different tooth heights are arranged as shown in FIG.

[0011]

[Action]

 The paper concavo-convex blade provided on the main body of the storage container was obtained by punching the paper with a single edge, and the direction of the punching process and the direction of entry of the packaging web into the paper concavo-convex blade when cutting. Therefore, the packaging web contacts the sharpest point, which is the tip of the uneven blade, and the breaking of the web starts at this sharpest point. Become.

【Example】

 FIG. 1 is a vertical side view showing an embodiment of the present invention, FIG. 2 is a perspective view of FIG. 1, and FIG. 3 shows the relationship between the paper uneven blade and the approach direction when cutting the packaging web in the present invention. FIG. 4 is a front view of a part of a paper uneven blade of the present invention, and FIGS. 5 and 8 are front views of a part of another embodiment of the paper uneven blade of the present invention. is there.

Reference numeral 1 denotes a storage container body, which is usually formed by using one piece of hard paper as a storage container forming piece and simulating it as a folded assembly. Reference numeral 2 denotes a packaging web accommodated in the accommodating container body 1, which is, for example, a plastic film or a metal foil, and is wound around the center core 3 in a roll shape. Reference numeral 4 denotes a paper saw blade, which is formed, for example, by a single-edged punching process on a part of the storage container forming piece, or is separately formed by hard paper, and a paper uneven blade is formed by a single-edged punching process. It is provided at a required portion of the container body 1.

When the paper concave-convex blade 4 is created by punching the single-sided blade, the single-sided blade collides with the paper piece to be the paper concave-convex blade 4 in the traveling direction X to form the concave-convex blade. As shown in FIG. 3, it becomes a concave-convex blade having oblique sides inclined in the thickness direction of the piece of paper. That is, each tooth 5 of the concavo-convex blade 4 has an obtuse angle A between the surface 6 on which the single blade collides and the hypotenuse 7, and the surface 8 on the back side of the surface 6 on which the single blade collides and the hypotenuse 7. The teeth 5 are formed so that the angle is an obtuse angle B. When the uneven blade 4 having such teeth 5 is upright, the packaging web 2 is cut into contact with the uneven blade 4 and is smoothly broken with the lightest force. The traveling direction of the web 2 can be reached by pulling out the packaging web 2 in the same direction Y as the single-blade punching direction X and hanging it up and down on the uneven blade 4.

[0015]

[Effect of device]

 This invention draws the packaging web wound in a roll form from the storage container body and stores it. In the packaging web storage container with a paper uneven blade that cuts with the paper uneven blade provided in the container body, the paper uneven blade is used. It should have been obtained by single-edged punching, and the direction of the paper uneven blade in the storage container body should be determined by the direction of the paper uneven blade's punching process and the packaging web guided by the paper unevenness. Since it is provided in the main body of the storage container so that the direction of movement is the same, it is possible to perform the packaging web very smoothly and with the lightest force even when the packaging web comes into contact with and breaks the paper uneven blade. This means that the paper concave-convex blade is housed so that the direction in which the paper concave-convex blade is punched out and the direction in which the packaging web is guided to enter the paper concave-convex blade are opposite to each other. It can be clearly recognized when compared to the case where it is provided on the container body. When the paper uneven blade is coated or impregnated with silicone oil or silicone resin, the packaging web has a good sharpness and the packaging web does not have stickiness after being cut.
