Description

[Detailed description of the device]

[0001]

[Industrial application]

 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. Uses a material that is as sharp as a blade and has high safety and is easy to dispose of.In addition, the length of the material is shortened to save material and improve handleability. This is to prevent damage to the cutter during the transportation process.

[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. In addition, since the roll has the full width, it is not only costly depending on the material, but also inferior in workability.In addition, when the blade is exposed, There are problems such as being easily damaged during the transportation process.

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 solves the various problems in the above-mentioned conventional technology, and is a cutter that is not only inferior to a metal blade in terms of sharpness but also has high safety, is easy to dispose of, and has excellent carton processability. We have developed a carton for storing rolls with a cutter that can completely protect the cutter during storage and transportation as well as in the vertical direction. In a carton in which a face plate, a lid plate, and a laminated plate, and side plates and glue strips at both ends in the width direction thereof are foldably installed in sequence through fold lines, a cutting line is provided on the laminated plate. A fixing plate is continuously provided through the laminated plate, and both sides are overcoated with a resin such as a cellulose resin, a urethane resin, or a polyester resin in the center of the back surface side of the laminated plate.

Further, the present invention is characterized in that a front plate, a bottom plate, a back plate, a lid plate, and a laminated plate are longitudinally bent, and a side plate and an adhesive margin piece are respectively bent at both ends in the width direction thereof by folding lines. In a freely arranged carton, a fixed plate is connected to the laminated plate via a cutoff line, and a cellulose resin, urethane resin, polyester resin, etc. are provided at the center of the back surface side of the laminated plate. The base of a cutter with a sharp-pointed tip, which consists of a hard fiber sheet obtained by treating cellulosic fibers with zinc chloride, over-coated on both sides with the resin of The roll storing carton with a cutter according to claim 1, wherein a slit for inserting the cutter is formed at a position corresponding to the tip of the cutter.

Further, according to the present invention, a front plate, a bottom plate, a back plate, a lid plate, and a laminated plate are arranged in the vertical direction, and a side plate and an adhesive margin piece are provided at both ends in the width direction of the plate through fold lines. In a carton that has been installed in order by folding, the fixing plate is connected to the stacking plate through a cutting line that protrudes in a trapezoidal or arcuate shape with the central portion facing the vertical end face. It also relates to a roll storage carton with a cutter.

[0008]

[Action]

 Regarding the cutter, a relatively small blade shape with various shapes such as triangular shape or heart shape is obtained from hard fiber sheet obtained by treating cellulose fiber with zinc chloride, which is overcoated on both sides with resin. Punch it out and attach it to the center of the back side of the laminated plate corresponding to the roll take-out edge of the roll carton with an adhesive, and further fix the fixing plate to the front plate with an adhesive or other means.

In use, when the fixing plate is cut off from the cutting line, the tip of the cutter is exposed from the center of the stacking plate, pierces the center of the rolled-out sheet, and cutting of the sheet is started. A cutter using a hard fiber obtained by treating a cellulosic fiber with zinc chloride has high water resistance, has an appropriate hardness, and is not inferior in sharpness of a roll to a metal cutter. In addition, the resin coating on both sides of the hard fiber makes the water resistance even more perfect. Further, after the cutter is used, the tip of the cutter is inserted into the slit of the front plate, whereby the stack plate is temporarily locked.

[0010]

【Example】

 The concrete contents of the present invention will be described below with reference to the illustrated embodiment. The front plate 1, the bottom plate 3, the back plate 6, the cover plate 8 and the stacking plate 9 are arranged in the longitudinal direction of the carton. The plate 1, the bottom plate 3, and the back plate 6 are respectively provided with glue margin tongues 2, side plates 4, folding tongues 5, and glue margin tongues 7 at fold lines a, b, and c, respectively. , D, and e, f, g, and h are foldably installed in sequence, and a fixed plate 12 is connected to the stack plate 9 via a cutoff line 11.

The cutoff line 11 has a protrusion 10 formed on the stacking plate side by projecting a central portion thereof into a substantially trapezoidal shape toward the longitudinal end face. The protruding portion 10 is not necessarily limited to the trapezoidal shape, and other methods such as a method of protruding the central portion of the cutoff line 11 toward the vertical end face in an arc shape may be used. The formation of such protrusions is more preferable because it acts more effectively by cutting the roll sheet when the finished carton is used.

Furthermore, a cutter 13 is attached to the center of the back surface side of the stack plate 9. The cutter 13 includes a hard fiber sheet 13c obtained by treating cellulosic fibers with zinc chloride as shown in FIG. 2, and a cellulosic resin, urethane resin, or polyester resin coated on both sides of the sheet. The material is composed of resin layers 13d and 13e made of resin such as resin. This plate is formed into a triangular shape, a heart shape, or any other cutter shape by using an appropriate punching die. To use.

The tip portion 13b of the cutter 13 may be sharply pierced so that it can be pierced into the center of the sheet to be cut. In this case, it is an acute angle according to FIG. 2, but it is not necessarily limited to this, and an obtuse angle is not always necessary. You may form in. Further, the tip end of the cutter tip portion 13b is not sharp as shown in FIG.

The above-mentioned hard fiber sheet 13c is made by laminating raw material paper made of purified organic natural fiber 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 industrialized material that has been made into an organic material. Due to the above-mentioned swelling and gelatinizing action, the fibrous structure has a semi-permeable, colloidal membrane structure, and has a high density, making it the most mechanically strong natural fiber material. It is also excellent in cold punching, bending, or squeezing, and has excellent wear resistance, impact resistance, and oil resistance.

For the resin layers 13d and 13e, 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.

In the embodiment, this is cut out into a triangular shape with a sharp tip, the tip portion 13b thereof is projected to the fixing plate 12 side, and the base portion 13a is attached to the stacking plate 9 with an adhesive or the like. wear. Further, a slit 1a for inserting a cutter is formed in the front plate 1 at a position corresponding to the tip portion 13b of the cutter 13.

A carton blank having the structure shown in FIG. 1 and showing the back surface of the front plate 1, the bottom plate 3, and the back plate along fold lines a, b, c, d and e, f, g, h. 6, the lid plate 8 and the stacking plate 9, and the front side plate 1, the bottom side plate 3 and the back side plate 6 at the widthwise ends of each of them, the adhesive margin tongue 2, the side plate 4, and the folding tongue 5 and the glue. The sub-tongue pieces 7 are each folded back to the inside to form a rectangular box body, and with the lid plate 8 opened upward, the roll R is housed inside, and finally the fixing plate 12 is placed. The back surface of the above is bonded and fixed to the front surface of the front plate 1 by the bonding portion 12a (see FIG. 3).

In use, when the fixing plate 12 is cut off from the stacking plate 9 along the cut line 11, the tip portion 13b of the cutter 13 hidden behind the fixing plate 12 is exposed.

The lid plate 8 is opened upward together with the stacking plate 9, and when a necessary amount of the sheet RS of aluminum or the like is fed out from the roll R inside, the stacking plate 9 is lowered downward, and the cutter 13 attached at the center is projected. After inserting the front end portion 13b into the sheet RS, the sheet RS is further pulled to easily cut the sheet RS.

In this case, when the above-mentioned sheet is a resin-based wrap film instead of aluminum, a necessary amount of the sheet RS is pulled out at the time of cutting the film, and the cutter tip portion 13b of the lapping plate 9 is rolled by the roller. Can be easily cut by inserting the sheet into the slit 1a of the front plate 1 together with the sheet RS and further pulling the sheet in that state. Further, when not in use, if the cutter tip portion 13b of the stacking plate 9 is inserted into the slit 1a of the front plate 1 as well, dust and the like will not enter the inner portion, and it can be used hygienically.

[Effect of the device]

 According to the present invention, as described above, the stacking plate of the roll storage carton is continuously provided with the fixing plate through the cut line, and the base of the relatively small cutter is fixed to the center of the back side of the stacking plate. Therefore, when the back surface of the fixed plate is bonded and fixed to the front surface of the front plate with an adhesive, the sharp tip of the cutter is hidden behind the fixed plate and completely Protected so that it is not only dangerous in storage and transportation but also non-destructive.

In addition, since the above-mentioned cutter uses a cutter formed by punching out a hard fiber sheet obtained by treating cellulose fibers with zinc chloride when both sides are overcoated with a resin, It has a high sharpness and is not inferior to a metal blade, but it does not hurt your hands, so it is highly safe, and because it can be incinerated together with the carton, it is easy to dispose of it, and its length is shortened. The material can be saved and the handling can be improved.

Further, when a slit for inserting the cutter is formed in the front plate at a position corresponding to the tip of the cutter, the stability is improved especially when the resin-based wrap film is cut.

Further, in the case where the central portion of the stack is projected in a trapezoidal or arcuate shape with the central end facing the end face in the vertical direction, the cutting performance of the sheets centering on the cutter is significantly improved.
