Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is for storing a long-rolled box-like roll for storing a roll wound in a long length, such as a wrap film or an aluminum foil, and cutting and taking out the roll as needed. Regarding the improvement of the cutter attached to the roll outlet of the carton and its manufacturing method, the cutter for roll cutting is made of a material that is as sharp as a metal blade but has high safety and is easy to dispose of. Is used, and in particular, wavy deformation in the length direction due to moisture absorption is prevented.

[0002]

2. Description of the Related Art A variety of cutters for cutting rolls, which are used in cartons for storing rolls, have been developed so far, and metal cutters such as tinplate are often used. . In recent years, instead of the above-mentioned metal material, the cutting blade of the roll is made of synthetic resin such as plastic (Shokai Sho 6).
No. 3-149834), one using a paper containing abrasive grains (the one disclosed in JP-A-58-64940), or a curing method in which a synthetic resin is impregnated and cured. The one using a paper blade (the one disclosed in Japanese Utility Model Laid-Open No. 51-150938) is known.

[0003]

However, a metal object is liable to be injured in handling and is always accompanied by danger, and it is necessary to remove the blade from the carton part for disposal and dispose of it separately. There are problems in that not only many difficulties are involved in processing but also hands are easily damaged.

Further, when a synthetic resin is used, it is not only necessary to separate it at the time of discarding it, but especially when incinerating vinyl chloride or the like, a toxic gas is generated, which is dangerous. Further, when the abrasive-containing paper is used, the abrasive particles tend to fall off during use, and there is a sanitary problem when used for foods. Further, when a resin-cured paper blade is used, it can be used to cut an aluminum foil, but it has poor sharpness against a wrap film and has a drawback that the type of roll to be stored is limited.

Therefore, recently, a paper cutter, which is excellent in terms of the above-mentioned disposal and safety, has been suddenly noticed. In particular, a hard fiber sheet obtained by treating a cellulosic fiber with zinc chloride is a paper-like material and has high strength, and therefore, it can be said that it is suitable as a cutter for a carton for storing rolls. However, even in this case, when it is processed and used as it is as a cutter for a roll storing carton, there are the following problems.

That is, when a cutter using a hard fiber sheet is attached to the outlet of a roll carton, when the humidity changes, the cutter will move in a relatively short time due to the difference in expansion / contraction ratio between the carton board and the hard fiber. There is a tendency to wavy in the length direction,
As a result, not only is the product unsatisfactory, but the cutting performance of the drawn sheet is poor, and the cutting line at the cutting end is irregular, which is not convenient. This is because even in a hard fiber sheet obtained by treating a cellulosic fiber with zinc chloride, the base paper is inevitably aligned along the papermaking direction at the stage of papermaking as in the case of a general paper material. A grain is generated in the length direction of the paper, and generally, it is cut in a direction orthogonal to the length direction of the paper (direction intersecting the grain) to form an elongated cutter. This is because the above-mentioned hard fiber sheet has a high expansion and contraction rate in the lateral grain direction (the direction orthogonal to the grain), among other types of paper.

[0007]

SUMMARY OF THE INVENTION Therefore, the present invention solves various problems in the prior art described above, and uses a hard fiber sheet excellent in both disposal property and safety as a raw material, and particularly due to its peculiar drawbacks. It is designed to prevent the deformation of the cutter due to moisture absorption at a certain place, and specifically, it is an opening edge in a box with a long box shape with a bottom, a side edge of a bottom plate, or a tip of a lid plate. In a cutter that has a length corresponding to the roll width and is attached with the blade tip protruding outward, the cutter is made of a hard fiber sheet obtained by treating paper with zinc chloride, and the fibers of the hard fiber sheet are , A roll carton cutter configured to face the length direction of the cutter.

Further, according to the present invention, the cutter is provided with a length corresponding to a roll width at an opening edge portion of a box having a long box shape with a bottom, a side edge portion of a bottom plate, or a tip portion of a lid. And also relates to a carton with a cutter, in which the blade tip is attached so as to project outward.

Further, the present invention relates to a carton with a cutter, which is attached to a carton for storing rolls in the form of a long box having a bottom, with the cutting edge of the cutter protruding outward, wherein the cutter is a hard fiber sheet whose paper is treated with zinc chloride Manufacture of a carton with a cutter that cuts the original fabric along its fiber direction and integrally adheres it to the opening edge of the carton, the side edge of the bottom plate, or the tip of the lid plate with an adhesive. Also related to law.

[0010]

Function: A long and narrow cutter having a length corresponding to the entire width of the roll storing carton is manufactured along the fiber direction of the cellulosic hard fiber sheet, and the thin cutter is formed, for example, in the box with a bottomed long box for storing roll. Attach it to the roll outlet of the edge with adhesive etc. with the tooth tips facing outward. Since the length direction of the cutter matches the fiber direction of the sheet, there is almost no expansion and contraction due to moisture absorption,
Therefore, it is less likely to be deformed.
