Abstract

(57) [Summary] (Modified) [Purpose] The cutter in the roll storage carton has a blade-shaped hard fiber sheet obtained by treating the cellulose-based fibers with zinc chloride when both sides are overcoated with a resin. By punching it out and using it, the safety and disposal property are improved. [Structure] A roll-storing carton that stores a roll wound in a long length and is provided with a cutter at the rim of the take-out opening so that the necessary amount is cut out, and the cutter is a cellulose resin, a urethane resin, or a polyester resin. Molded from a hard fiber sheet obtained by subjecting cellulosic fibers to zinc chloride treatment, which was overcoated on both sides with a resin such as a resin. This makes it highly water resistant,
It is possible to obtain a roll carton which is as sharp as a metal blade and is safe without damaging a hand and which can be easily disposed of.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a carton for storing rolls, which stores rolls wound in a long length such as wrap film and aluminum foil, and cuts and removes them as needed. It is made of a material that is as sharp as a blade, yet highly safe, and that can be easily disposed of.

[0002]

[Prior Art]

 Various cartons for storing rolls have been developed so far, and cutters for cutting rolls are often made of metal such as tin or aluminum. Further, recently, as the cutting blade of the roll, one made of synthetic resin such as plastic is used in place of the above-mentioned material made of metal (disclosed in Japanese Utility Model Laid-Open No. 63-149834), and grinding blade. The one using a paper containing particles (the one disclosed in JP-A-58-64940) or the one using a hardened paper blade impregnated with a synthetic resin and cured (Actual Development No. 51- (Japanese Patent Laid-Open No. 150938) and the like are known.

[0003]

[Problems to be solved by the device]

 However, metal objects are liable to hurt hands during handling, and are always dangerous, and it is necessary to remove the blade from the carton part and dispose of each at the time of disposal, which causes many difficulties in disposal. There are problems such as accompaniment.

In addition, when a synthetic resin product is used, it is not only necessary to separate it when disposing of it, but also it is easy to burn the furnace because the combustion energy is large during incineration, especially when incinerating vinyl chloride or the like. Toxic gas is generated and is dangerous. Furthermore, when the abrasive-containing paper is used, the abrasive particles tend to fall off during use, and there is a sanitary problem when used in foods. Further, when a resin-cured paper blade is used, it is difficult to allow the resin to soak in during processing, and there is the dislike of insufficient strength.

[0005]

[Means for Solving the Problems]

 Therefore, the present invention has solved the above-mentioned various problems in the prior art, and developed a cutter that is as sharp as metal blades, yet highly safe, and easy to dispose. The roll carton has a roll at the edge of which is equipped with a cutter and is cut to the required amount to be taken out. The cutter is made of cellulose resin, urethane resin, polyester resin. A carton for storing rolls with a cutter, characterized in that it comprises a hard fiber sheet obtained by treating cellulosic fibers with zinc chloride, both sides of which are overcoated with a resin such as.

[0006]

[Action]

 A blade shape was punched out from a hard fiber sheet obtained by treating cellulosic fibers that had been overcoated with resins with zinc chloride, and this was cut at the roll carton roll edge with an adhesive or the like. Attach it for use.

The cutter using the hard fiber obtained by treating the cellulosic fiber with zinc chloride has high water resistance and also has an appropriate hardness, and has a sharpness of roll as compared with a metal cutter. Is not inferior. In addition, the resin coating on both sides of the hard fiber makes the water resistance even more perfect.

[0008]

【Example】

 Hereinafter, the specific contents of the present invention will be described with reference to the illustrated embodiment, where 1 is a cutter and 6 is a carton. The cutter 1 comprises a hard fiber sheet 2 obtained by treating a cellulosic fiber with zinc chloride, and resin layers 4 and 5 coated on both sides of the sheet. Cutter 1 is formed.

That is, in the hard fiber sheet 2, raw material paper made of purified organic natural fibers was laminated and integrated into a layer thickness of about 0.2 to 0.4 mm by utilizing the swelling and gelatinization reaction of zinc chloride. It is an organic industrial material. Due to the above-mentioned swelling and gelatinizing action, the fiber structure has the shape of a gelatinous semipermeable membrane and has a high density, and it has the highest mechanical strength as a natural fiber material. It can be cold punched, bent, or drawn, and has excellent wear resistance, impact resistance, and oil resistance.

For the resin layers 4 and 5, various resins such as cellulose resins such as nitrocellulose and ethyl cellulose, urethane resins, polyester resins, and acrylic resins can be used. Roll coating is generally used as the coating method, and the resin thickness is within a range of 1 to 5 μm so that pinholes do not occur.

Further, the blade portion 3 of the cutter 1 is preferably formed in a saw-tooth shape by using a cutting die in order to maintain the sharpness of the cutting edge. Regarding the shape of the blade, if the pitch (a) and the height (b) are both less than 1.0 mm, it becomes difficult to cut both the aluminum foil and the wrap film, and conversely, the pitch is 1.7 mm and the height is high. When the thickness exceeds 2.0 mm, the sharpness is further improved, but the strength is deteriorated, the catching is reduced, and it becomes difficult to catch the trigger of cutting, and the cutting surface becomes misaligned and dirty.

Therefore, regarding the shape of the blade, as shown in FIG. 2, pitch (a): 1.0 to 1.7 millimeters, preferably 1.2 to 1.5 millimeters range height (b): 1. 0 to 2.0 millimeters, preferably 1.2 to 1.5 millimeters range should be within the above range.

The cutter 1 having the above-described structure is attached to the roll take-out port edge portion of the roll storing carton. That is, FIG. 3 shows a roll-shaped carton 6 having a standard shape. A rectangular box with a bottom having side portions 8 on both left and right ends is opened and the roll 12 is stored inside. The lid portion 9 and the insertion tongue piece 10 are connected to each other on the rear surface side, and an outlet is formed between the lid portion 9 and the opening edge portion 7 of the front surface portion 11.

The cutter 1 has its blade 3 directed toward the opening (upper part) of the carton 6 and has a back surface such as a polyolefin-based adhesive or other solvent-drying adhesive or hot-melt adhesive. It is applied, and it is used by being integrally attached to the opening edge portion 7 of the carton 6 described above.

[0015]

[Effect of the device]

 As described above, the present invention uses a cutter formed by punching out a hard fiber sheet obtained by treating cellulose fibers with zinc chloride, which has been overcoated on both sides with a resin, and therefore has a high water resistance. It is expensive and has a sharpness that is not inferior to that of a metal blade, but it does not hurt your hands, so it is highly safe, and because it can be incinerated with the carton, disposal is easy.

Further, regarding the shape of the blade of the cutter, pitch (a): 1.0 to 1.7 mm, preferably 1.2 to 1.5 mm range height (b): 1.0 to 2.0 mm In the case of preferably in the range of 1.2 to 1.5 mm, the balance between good sharpness and high strength is good, and the practicality is improved.
