[0002]

2. Description of the Related Art Conventionally, there is provided a storage body for storing a long roll of wrap film, aluminum foil or the like used for packaging foods and the like, and capable of cutting the long roll pulled out from the roll to an arbitrary length. It is used. Such a storage body,
A metal cutting tool having saw teeth was fixed to the box body. However, since the box body of the container with the metal cutting tool is made of paper, it is necessary to separate the metal cutting tool from the box body at the time of discarding the container body, and the disposability becomes a problem. ing. Further, although the metal cutting tool is excellent in cutting property and durability, there is also a problem that the metal cutting tool is easily scratched when touched by the hand.

Therefore, instead of a metal cutting tool, a hardened paper cutting tool such as valganized paper is used, or a sawtooth shape is directly applied to a paper base material for forming a container. Proposed is a container that is formed and impregnated with α-cyanoacrylate at the edge to integrally provide a cut portion.

[0004] In such a storage body, it is possible to prevent the cutting tool from damaging the long body which is the contents, the other storage bodies from being damaged, and the cutting tool from being contaminated or damaged in the distribution stage. For this reason, the structure is such that the cutting portion is covered with the paper base material that constitutes the storage body before use.

For example, in the housing disclosed in Japanese Utility Model Publication No. 7-28105, a cut portion in which an edge portion having a sawtooth shape is impregnated with α-cyanoacrylate is arranged at a lower end portion of a front lid, and a front side wall is provided. The cover folded back at the extending perforations (hereinafter referred to as cover 1) is further folded back at the folds so as to protect the cut portion at the lower end of the front lid (hereinafter, this folded portion is referred to as cover 2). In addition, the cover 2 is formed with two perforations for forming a cut band at portions located above and below the cut portion in parallel with the fold line. In use, the cut band is removed to expose the cut portion at the lower end of the front lid, the cover 1 is removed by perforations, or the cover 2 is folded back into the storage body.
In the above, the portion left above the cut portion is bonded to the front lid and acts as a reinforcing material when cutting a long body such as a wrap film.

A roll R having a long body wound around a core C is provided inside a bottom plate 2, a front plate 3, a rear plate 4, an upper lid 5, and side plates (not shown). It is stored.

In the storage body 1 "of the present invention as described above, since the cutting portion 21 of the front lid portion 8 is sandwiched between the sliding plate portion 6 and the protective plate portion 7, the cutting portion 21 is a stored item. A certain roll R
Therefore, the cutting portion 21 itself is prevented from being contaminated and damaged, and the cutting portion 21 itself is prevented from being damaged.

In such a storage body 1 "of the present invention, in the blank plate as shown in FIG. 3, the perforation 6a is formed at a predetermined distance from the bending line 16 of the sliding plate portion 6 and the protection plate portion 7 is formed. It can be created by assembling a blank plate in which one perforation 17 is formed at the position of the perforation 17b without forming the perforation 17a. In this case, first, each component 2, 3 of the blank plate is formed. , 4, 5,
Bending 7,8,9a, 9b, 9c, 9d, 9e along the folding lines 11,12,13,15,16,18 to the back surface of the blank plate (the surface which is the inner surface of the storage body), and the sliding plate portion. Bend 6 along the fold line 14 to the front side of the blank plate. Next, the surface of the front plate portion 3 and the surface of the sliding plate portion 6 are fixed to each other with the adhesive A1 between the bending line 14 and the perforations 6a (all surface adhesion, line adhesion, or spot adhesion). Further, the cutting portion 21 is located between the perforations 6 a and the perforations 17 and is sandwiched between the sliding plate portion 6 and the protection plate portion 7 so that the back surface of the protection plate portion 7 and the front lid portion 8 are provided.
And the surface thereof are fixed by the adhesive A3 (any of whole surface adhesion, line adhesion and spot adhesion). Next, with the roll R placed inside, the side plate portions 9a, 9a
b and 9c are fixed to each other, and side plates 9d and 9e are fixed to each other.

When the container 1 "(FIG. 8) of the present invention is unsealed and used, first, in the sliding plate portion 6, a portion (cutout portion) 6A sandwiched between the folding line 16 and the perforation 6a and protection. The fold line 16 of the plate portion 7 and the portion (cutout portion) 7A sandwiched by the perforations 17 are removed by cutting along the perforation 6a and the perforation 17. The cutout portions 6A and 7A are collectively removed. , And can be easily removed by grasping one end thereof and pulling it along the perforations 6a and the perforations 17. When the cutouts 6A and 7A are removed in this manner, they were covered with the protective plate portion 7. The cut portion 21 is exposed. Simultaneously with the exposure of the cut portion 21, an opening is formed between the front plate portion 3 and the rear plate portion 4. The perforations 6a and the perforations 1
7 is preferably relatively easy to cut in order to facilitate separation and removal of the cut-off portions 6A and 7A. For example, the cut / uncut ratio is 20/1 to 1/1, and the uncut length is It can be 0.5 to 5 mm.

As described above, in the container 1 "of the present invention, the unsealing work is completed by one operation of separating and removing the cut-off portion 6A of the sliding plate portion 6 and the cut-off portion 7A of the protection plate portion 7, and the roll R is temporarily removed. No complicated operation such as taking out from the container 1 is required.

FIG. 9 is a vertical sectional view showing the state of the container of the present invention after such opening. As shown in FIG. 9, the elongated body is pulled out from the roll R. At this time, the elongated body comes into contact only with the folding line 14, the sliding plate portion 6 and the front lid portion 8, and the conventional storage body The contact between the elongated body and the cut trace (the trace of the member cut off by perforations or cut lines) that occurred during opening as seen in Fig. 2 does not exist in the container 1 "of the present invention. The sliding property between the container and the storage body 1 ″ is good, and no catching or damage occurs when the elongated body is pulled out. Further, the front lid portion 8 is integrated and reinforced with the remaining protection plate portion 7B which is not removed.
Since the front plate 3 is integrated and reinforced with the remaining sliding plate 6B that has not been removed, the front lid 8 and the front plate 3 having the cutting portion 21 when the long body is cut are deformed. There is little and it is easy to cut a long body.

In the example shown in FIGS. 3 and 5, the ridge line formed by the apexes of the sawtooth shape of the cutting portion 21 is a straight line, but the present invention is not limited to this and any shape may be used. You can For example, as shown in FIGS. 10 and 11, the ridgeline formed by the vertices of the sawtooth shape may have a central portion projecting from both ends or the vicinity of both ends. Further, as shown in FIG. 12, the shape may be such that both ends or the vicinity of both ends of the ridgeline formed by the apexes of the sawtooth shape are projected more than the central part. Then, regardless of the shape of the ridge line, the protection plate portion 7B that remains without being removed is fixed to the front lid portion 8 having the cutting portion 21 as described above, and the cutting portion 21 is protected by this protection. In the state where it projects from the plate portion 7B, it is advantageous in terms of durability that the projected width of the cutting portion 21 is small as long as it does not hinder the cutting of the elongated body. For this reason, at least the perforations 17b (the same applies to the perforations 17) are shown in FIGS.
As shown in 2, it is preferable that the shape corresponds to the shape of the ridge.

Next, the cutting section 21 which constitutes the container 1 of the present invention will be described. The cutting portion 21 has a sawtooth shape as described above, and the front lid portion 8 may have a sawtooth shape directly formed on the tip portion thereof. In this case, a water-resistant resin may be applied to at least the cut portion 21 forming portion of the front lid portion 8 in order to impart water resistance. As the water resistant resin, polyester resin, acrylic resin, vinyl chloride resin, vinyl chloride / vinyl acetate copolymer, polyvinyl alcohol resin, polyvinyl butyral, styrene resin, epoxy resin, polyurethane resin, cellulose resin Examples thereof include resins, phenol resins, xylene resins, urea resins, melamine resins, terpene resins, ketone resins, amide resins, and silicone resins. Further, as will be described later, when the abrasive grains are fixed to the sawtooth-shaped portion, the above-mentioned water resistance may be given in advance, or after the abrasive grains are fixed to the sawtooth-shaped portion, or before and after the fixing of the abrasive grains. You may go in.

In the present invention, the durability of the cut portion 21 may be further improved by subjecting at least the cut portion 21 forming portion of the front lid portion 8 to a hardening treatment. This curing treatment is performed on the cut portion 21 with styrene / butadiene copolymer resin, acrylonitrile / butadiene copolymer resin, methylmethacrylate / butadiene copolymer resin, chloroprene copolymer resin, acrylic resin, acrylic resin.
It can be carried out by impregnating any one or two or more resins such as vinyl acetate copolymer resin, paraffin wax and microcrystalline wax. Further, the above-mentioned treatment for imparting water resistance may be performed after such a curing treatment.

FIG. 13 is a perspective view showing an example of such an integrally-molded cutting portion 21, which has a saw-toothed portion 22 formed on the end side of the front lid portion 8. This sawtooth shaped part 2
A plurality of triangular saw teeth 23 are arranged so that both ends of the base thereof are connected to each other. Abrasive grains 25 are fixed to a desired region of the sawtooth portion 22 with a resin 24. In the illustrated example, the abrasive grains 25 are fixed to the upper end surface 22a and the side surface 22b of the sawtooth-shaped portion 22, but the abrasive grains 25 may be fixed to only the upper end surface 22a of the sawtooth-shaped portion 22. On the contrary, if the abrasive grains are unnecessarily adhered to the area other than the saw-tooth-shaped portion 22 of the cutting portion 21, when a long body such as a wrap film is cut, the portion other than the cut portion is damaged or the storage body is It is not preferable because it may cause scratches.

The resin 24 for fixing the abrasive grains 25 in the cutting portion 21 constituting the present invention is a polyester resin, an acrylic resin, a urethane resin and a polyester urethane resin having a glass transition temperature of 50 ° C. or higher. Resin group A consisting of If the glass transition temperature is 50 ° C. or lower, the resin component may change to cause tackiness, or the abrasive grains 25 may fall off the cut portion 21, which is not preferable. Further, by adding a curing agent to the resins of the resin group A, the adhesive holding property of the abrasive grains 25 can be further enhanced. In this case, as the curing agent, polyethyleneimine type, organic titanium compound type, polyolefin type, polybutadiene type, isocyanate type, polyester urethane type, polyether urethane type and the like can be used.

Further, the resin 24 for fixing the abrasive grains 25
As, epoxy resin, amino resin, phenol resin, cellulose derivative resin, natural polymer resin,
A resin group B including a polyvinyl alcohol-based resin, a polyvinyl butyral-based resin, a silicon-containing compound-based resin, a silane-based resin, and a silica-based resin can be mentioned. The resins of such a resin group B may be a curing agent as described above,
The curing time can be shortened by adding a curing aid or the like.

Further, the resin 2 for fixing the abrasive grains 25
4 is styrene / butadiene copolymer resin, acrylonitrile / butadiene copolymer resin, methyl methacrylate / butadiene copolymer resin, chloroprene copolymer resin, acrylic resin, acrylic / vinyl acetate copolymer resin, paraffin wax And a resin group C composed of latex (emulsion) such as microcrystalline wax.

The resin 24 may be composed of one kind or two or more kinds of the above resin groups, or a combination of resins of different resin groups, but preferably has a glass transition temperature of 50 ° C. The polyester resins and acrylic resins described above are used.

Further, as the resin 24, an ultraviolet curable resin or an electron beam curable resin made of at least one resin of acrylate monomer, polyester acrylate, epoxy acrylate, urethane acrylate, silicon acrylate and polybutadiene acrylate can be used. By adding a photopolymerization initiator or a sensitizer to such an ultraviolet curable resin or an electron beam curable resin, it is possible to cure the resin 24 in a short time even if the film thickness of the resin 24 increases. It will be possible.

As the abrasive grains 25 used in the cutting portion 21 constituting the present invention, alumina, silicon carbide, diamond,
Cubic boron nitride, antimony trioxide, silicon nitride, siliceous, metal powder such as aluminum, iron, zinc, antimony, metal oxide, cerium oxide, titanium carbide, titanium boride, titanium hydroxide, titanium nitride, Examples thereof include titanium compounds such as titanium silicide and titanium selenide, and particles such as zirconium oxide. Among these, especially alumina,
Silicon carbide is preferably used. Such abrasive grains 25
Has an average particle size of about 2 to 500 μm, preferably 8 to 20
It is about 0 μm. When the average grain size of the abrasive grains 25 is less than 2 μm, the piercing property of the saw teeth 23 into a long body such as a wrap film is deteriorated, and when it exceeds 500 μm, the adhesiveness with the resin 24 is decreased and the saw teeth are formed. Abrasive grain 2 from shaped portion 22
5 occurs, and the edges of the sawteeth 23 become sharper and larger than necessary, which is not preferable because there is a risk of injury when touched with a hand.

By combining two or more of the above powders as the abrasive grains 25, the cuttability of the cutting portion 21 can be improved. That is, by selecting the shape and size of the abrasive grains and combining the abrasive grains of about 40 μm with the small abrasive grains of about 4 μm, the adherence density of the abrasive grains is increased and the cutting property is improved.

When the abrasive grains 25 as described above are fixed to the saw-toothed portion 22 with the resin 24, the abrasive grains are 0.8 to 100 parts by weight, preferably 2 to 50 parts by weight, relative to 1 part by weight of the resin. To do so. When this ratio is less than 0.8 parts by weight, the amount of abrasive grains attached to the saw teeth 23 forming the saw tooth-shaped portion 22 becomes too small, the piercing property of the saw teeth 23 into a long body is insufficient, and the cutting property is poor. It becomes stable, and cutting failure may occur, which is not preferable. Further, if the amount exceeds 100 parts by weight, defective fixing of the abrasive grains may occur, and further, as will be described later, the resin coating material containing the abrasive grains is coated with the sawtooth-shaped portion 22.
When the cut portion 21 is formed by applying the varnish to the resin coating material, the viscosity of the resin coating material increases, and the settling of the abrasive particles in the resin coating material occurs, resulting in a significant decrease in coatability.

FIG. 14 is a partial front view of the cutting portion shown in FIG. The abrasive grains 25 fixed to the saw-toothed portion 22 via the resin 24 are omitted. In FIG. 14, the triangular saw teeth 23 forming the saw tooth-shaped portion 22 of the cutting portion 21 have a bottom length L of 0.1 to 5.0 mm and a height H of 0.1 to 5.0 mm. Is preferred. If the size is less than the above range, the space between the saw teeth 23 is filled with the abrasive grains 25 and the saw tooth shape is not formed, which is not preferable. On the other hand, if it exceeds the above range, the saw teeth 23 are likely to be broken and the durability is deteriorated. Also, the triangular saw teeth 23
The radius of curvature R of the apex 23a is preferably 0.1 mm or more. When the radius of curvature R is less than 0.1 mm, the adhesiveness between the resin 24 and the abrasive grains 25 at the apex 23a is reduced, the adhesiveness of the abrasive grains 25 is also reduced, and the cutting property is deteriorated. Bending is likely to occur and durability is insufficient. Further, the disposition pitch P of the above-mentioned triangular saw teeth 23 is preferably 0.1 to 10.0 mm. If the arrangement pitch P is 0.1 mm or less, it becomes difficult to form the sawtooth shape on the tip of the front lid portion 8, and the sawtooth 23 is filled with the abrasive grains 25, so that the sawtooth shape is not formed. On the other hand, if the arrangement pitch P exceeds 10.0 mm, the continuity of cutting by the saw teeth 23 is lost and the cutting property becomes insufficient.

If the dimensions, the radius of curvature and the arrangement pitch of the saw teeth 23 are within the above ranges, for example, as shown in FIG. 15, there may be a region where no saw teeth exist between the saw teeth 23. Alternatively, as shown in FIG. 16, triangular saw teeth 23 having the same height H but different bottom lengths L are arranged at different pitches, or as shown in FIG. It is also possible to form the saw-tooth-shaped portion 22 in which the saw-tooth 23 having a triangular shape with different height H is arranged at the same pitch.

When the size is less than the above range, the amount of resin coating containing abrasive grains is reduced, the abrasive grain density is reduced and the cutting property becomes unstable, and the space between the saw teeth 33 is filled with the abrasive grains. This is not preferable because the sawtooth shape is not formed. On the other hand, if it exceeds the above range, the rigidity of the saw teeth 33 is apt to be broken and the durability is deteriorated. Further, the radius of curvature R of each apex 33a of the trapezoidal sawteeth 33 is 0.1 mm or more.
The arrangement pitch P of 3 is preferably 0.5 to 10.0 mm. By making the saw teeth 33 have a trapezoidal shape as described above, the directionality at the time of cutting the long body becomes good.

If the size, the radius of curvature, and the arrangement pitch of the saw teeth 33 are within the above ranges, for example, as shown in FIG. 19, the trapezoidal saw teeth 33 are connected to each other at the bottom end thereof. It may be. Also, although the heights H are the same,
Trapezoidal saw teeth 33 having different bottom lengths are arranged at different pitches, or trapezoidal saw teeth 33 having different heights H are arranged at the same pitch.
It can also be. In FIG. 19, the abrasive grains fixed to the saw-toothed portion 32 via the resin are omitted.

It is preferable that it is 3.0 mm. If the size is less than the above range, the amount of the resin coating material containing abrasive grains attached decreases, the abrasive grain density decreases, and the cuttability becomes unstable. On the other hand, if it exceeds the above range, the rigidity of the saw teeth 43 is apt to be broken and the durability is deteriorated. Further, it is preferable that the radius of curvature R of the apex 43a of the heptagonal sawteeth 43 is 0.1 mm or more, and the arrangement pitch P of the sawteeth 43 is 0.5 to 6.0 mm.

FIG. 21 is a partial front view showing another example of the cutting portion constituting the present invention. In FIG. 21, the cutting portion 21 has a sawtooth shaped portion 52 formed at the tip of the front lid portion 8.

If the size is less than the above range, the amount of the resin coating material containing abrasive grains attached decreases, the abrasive grain density decreases, and the cuttability becomes unstable. On the other hand, if the amount exceeds the above range, the rigidity of the saw teeth 53 is apt to be broken due to insufficient rigidity, resulting in poor durability. Further, it is preferable that the radius of curvature R of the apex 53a of the heptagonal sawteeth 53 is 0.1 mm or more, and the arrangement pitch P of the sawteeth 53 is 0.9 to 7.5 mm. As described above, by forming the saw teeth 53 into a heptagonal shape in which a triangle is placed on a rectangular body and providing the upper side portion of the rectangular body, the directionality at the time of cutting the wrap film is improved.

In the example shown in FIG. 21, one triangular tip is formed, but by forming two or more triangular ones, the amount of resin coating material containing abrasive grains is increased to improve the cutting property. You can also let it.

FIG. 22 is a partial front view showing another example of the cutting portion constituting the present invention. In FIG. 22, the cutting portion 21 has a sawtooth shaped portion 62 formed at the tip of the front lid portion 8. The sawtooth-shaped portion 62 is formed by arranging a plurality of bow-shaped sawteeth 63 so that both ends of the bottom side are connected to each other. Abrasive grains are fixed by resin to at least the upper end surface of the sawtooth portion 62. Note that, in FIG. 22, the abrasive grains fixed to the sawtooth portion 62 via the resin are omitted. The arched fan-shaped sawteeth 63 forming the sawtooth-shaped portion 62 of the cutting portion 21 shown in FIG. 22 have a radius r of 0.2 to 6.0 m.

5.0 mm, pitch P of saw teeth 63 is 0.5 to 15 m
m is preferable. If the size is less than the above range, the amount of the resin coating material containing abrasive grains attached decreases, the abrasive grain density decreases, and the cuttability becomes unstable. On the other hand, if the thickness exceeds the above range, the rigidity of the saw teeth 63 is apt to be broken and the durability is deteriorated.

Further, the sawtooth-shaped portion of the cutting portion which constitutes the present invention has two or more of the above-mentioned triangular sawtooth, trapezoidal sawtooth, polygonal sawtooth and bow sawtooth.

After making a cut in the elongated body, the abrasive grains fixed between the saw teeth 123 (the portion where the saw teeth do not exist) have a high cutting directionality.

Next, a method of forming the cutting portion of the integrally molded die in which the above-mentioned abrasive grains are fixed will be described.

In the method of producing the cutting portion which constitutes the container of the present invention, as shown in FIG.
The sawtooth-shaped portion 132 is formed on the surface of the sawtooth-shaped portion 132, and the resin paint 134 containing abrasive grains is applied to at least the upper end surface (the upper end surface and the side surface in the illustrated example) of the sawtooth-shaped portion 132. Next, as shown in FIG. 32 (B), the front lid part 8 is passed through the slit 142 having a predetermined width provided in the slit jig 141. As a result, the excess resin paint 134 on the front lid 8 is removed. afterwards,
The resin coating material 134 on the saw-toothed portion 132 is cured to form a cut portion. It is generally preferable that the width of the slit 142 is set to be about 90 to 150% of the thickness of the front lid portion 8.

In this way, the extra resin paint 1 on the front lid 8
By removing 34 by the slit 142, the abrasive grains are not unnecessarily fixed to the area other than the sawtooth-shaped portion 132, and when cutting the long body, damage to a portion other than the cut portion, as will be described later. This prevents damage to the storage compartment.

The resin paint used to make the above cut portion is
The above-mentioned resin for fixing abrasive grains contains abrasive grains. The resin used for the resin coating may be a combination of two or more resins such as polyester resin-acrylic resin, acrylic resin-urethane resin, urethane resin-vinyl acetate resin, and the like.

The amount of abrasive grains contained in the resin can be appropriately set according to the particle size of the abrasive grains, and 0.8 to 100 parts by weight of the abrasive grains is contained with respect to 1 part by weight of the resin (solid content). , Preferably 2 to 50 parts by weight. If this ratio is less than 0.8 part by weight, the amount of abrasive grains attached to the saw teeth forming the saw tooth-shaped portion will be small, the piercing property of the saw teeth into the elongated body will be insufficient, and the cutting performance will become unstable, resulting in cutting. This is not preferable because defects may occur. On the other hand, if it exceeds 100 parts by weight, the viscosity of the resin coating material increases, and the settling of abrasive grains in the resin coating material occurs, resulting in a significant decrease in coatability. Specifically, for example, 5 parts by weight (for a particle size of about 60 μm) to 60 parts by weight (for a particle size of about 2 μm) of abrasive particles can be used with respect to 1 part by weight of the resin.

The resin coating composition as described above may be one in which an anti-settling agent such as silica or polyethylene oxide is added in order to stabilize the ink dispersibility. Further, an antistatic agent such as a surfactant, an antistatic agent, or a conductive agent may be added in order to prevent dust and the like from adhering to the coated portion coated with the resin coating material. Further, a coloring agent may be added to the resin paint so that the abrasive grain fixed region can be seen.

As another example of the method for producing the cut portion constituting the container of the present invention, a resin coating material containing no abrasive grains is applied to at least the upper end surface of the sawtooth portion of the front lid portion 8 and then the predetermined width is applied. It is also possible to remove excess resin paint on the paper substrate using the slits and then attach the abrasive particles to the resin paint application surface. In this case, the method for attaching the abrasive particles to the resin coating surface is electrostatic coating, spraying with air, allowing the abrasive particles to drop onto the resin coating surface, or applying the resin coating on the paper base to the abrasive particles. Any method such as pressure-bonding the surfaces may be used.

The cutting portion constituting the container of the present invention has a saw-tooth shape directly formed on the front lid portion 8 as described above, or a separate cutting tool is fixed to the front lid portion 8. It may be In this case, the cutting tool may be a paper base material having a sawtooth shape formed at the tip portion thereof, a resin or wooden base material having a sawtooth shape, etc., as in the case of the above-mentioned integral molding. Good.

In the case of a resin cutting tool, usable resins include polyester resin, acrylic resin, polycarbonate resin, polyamide resin, ABS resin, polypropylene resin, polystyrene resin, inorganic filler-containing polyolefin resin, degradable plastic. Etc. can be mentioned. As the above-mentioned inorganic filler-containing polyolefin resin, for example, polypropylene resin or polyethylene resin containing an inorganic filler such as calcium carbonate or magnesium silicate can be used, and the inorganic filler content is about 30 to 50% by weight. preferable. The above degradable plastics include photodegradable plastics and biodegradable plastics. As the photodegradable plastic, for example, a copolymer of ethylene and carbon monoxide,
Polyethylene (Density 0.900 to 0.950 g / cm
³ , a mixture of a melting index (MI) of 0.4 to 40) and an organic acid metal salt and / or metal oxide, and the like. Examples of biodegradable plastics include polyesters that are polymerized by microorganisms. Examples of such polyesters include 3-hydroxybutyrate and 3
-Random copolymerized polyester with hydroxyvalerate, 3-hydroxybutyrate-based polyester obtained by supplying valeric acid to hydrogen bacteria, and the like can be mentioned. Also, as biodegradable plastics, polyethylene and
Mixtures of polycaprolactone, starch and the above polyesters can also be used.

In the case of a wooden cutting tool, a hard and elastic material is preferable, and for example, a material made by processing wood such as bamboo, willow, cherry tree, and cypress can be used.

The saw-tooth shape to be formed can be a saw-tooth shape that can be adopted for the cutting portion of the above-mentioned integral molding die.
When a resin having a particularly high hardness is used, the saw-tooth shape similar to that of the conventional metal cutting tool can be used.

The container of the present invention is not limited to the above embodiment. For example, by applying a resin such as an acrylic ultraviolet curable resin or a polyamide resin in a predetermined shape on the back surface of the sliding plate portion 6 or by sticking a seal having a predetermined shape formed of these resins, a resin film You may form a stopper part for preventing a long body, such as the above, from rewinding inside the storage body.

As described above in detail, according to the present invention, since the cutting portion is located between the sliding plate portion and the protective plate portion, which are attached to the front plate portion, in the state before use, the cutting portion is used. Prevents damage to the roll-shaped long body that is the contained object, contamination and damage to the cut part from the outside, and removes the protective plate part between perforations during use or protects the sliding plate part between perforations By removing the plate portion, the cut portion is exposed, and the rolled elongated body passes between the sliding plate portion and the front lid portion after contacting the bending line between the front plate portion and the sliding plate portion. Since it is pulled out to the outside of the storage body, the sliding property between the roll-shaped long body and the storage body is good, and it is effectively prevented from being caught or damaged when the roll-shaped long body is pulled out. With the protective plate part that is attached and reinforced, and the front lid part remains without being removed. Because the reinforced Ri intertwined with deformation less cutting performance with high durability of the front plate and the front lid (cut portion) is good, the effect is achieved that is superior in handling feeling.
