And a protection plate 7 connected to the other end of the front cover 6 through a cutout line A, and a protection plate 7 connected to the other end of the protection plate 7 via a broken line e. Auxiliary plate 8,
The other end of the auxiliary plate 8 has a cutting plate 9 connected with several bridge-shaped jumpers B at several places. At the end of the cutting plate 9 on the auxiliary plate 8 side, a sawtooth-shaped cutting portion 10 is formed. The back surface of the cutting plate 9 and the back surface of the front lid 7 are fixed by an adhesive A1, while the auxiliary plate 8
Is detachably bonded to the surface of the front plate 3 via an adhesive A2. A roll R in which a long body is wound around a core C is accommodated in the inside surrounded by the bottom plate 2, the front plate 3, the rear plate 4, the upper cover 5, and a side plate (not shown).

In the storage box 1 of the present invention as described above, the cut portion 10 of the cutting plate 9 is located between the front plate 3 and the protection plate 7, and therefore, the cut portion 10 is a stored item. It does not cause any damage by contacting the roll R or any other storage box, and prevents the cutting section 10 from being contaminated or damaged.

The storage box 1 of the present invention as described above can be manufactured by assembling a blank 11 formed by punching a paper base material. FIG. 2 is a development view showing an example of the blank 11 used for the storage box of the present invention. In FIG. 2, in the blank 11, the front plate 3 is connected to one side of the bottom plate 2 via a broken line a, and the rear plate 4 is connected to the other opposite side of the bottom plate 2 via a broken line b, c, d. 5 and the front cover 6 are sequentially connected, a protection plate 7 is connected to the front cover 6 through a cut line A, and an auxiliary plate 8 is connected to the protection plate 7 through a broken line e. The cutting plates 9 are connected by bridge-shaped jumpers B. Also,
The blank 11 includes side plates 2a, 3a, 4a, 5a, and 6a of a predetermined shape connected to the respective sides of the bottom plate 2, the front plate 3, the rear plate 4, the upper lid 5, and the front lid 6 via broken lines f and f '. , Side plate 2
a ', 3a', 4a ', 5a', and 6a '. Further, the width of the front cover 6 (the distance from the broken line d to the cut line A) is smaller than the width of the corresponding position of the cutting plate 9 (the distance from the leading end of the saw-tooth cut line B to the other end). Things. In this case, the difference between the width of the front lid 6 and the width of the cutting plate 9 can be appropriately set according to the material of the cutting portion 10, the size of the sawtooth shape, and the like. It is preferable to set the length to about 2 mm. In the illustrated example, the side plates 2a, 4a, the side plates 2a ', 4
The semi-circular cuts S and S 'are respectively formed in a'. The cuts S and S ′ are for preventing the roll R from jumping out by folding the cut inside the storage box.

As the paper base material for forming the blank 11 as described above, white paperboard, paperboard such as manila, and processed paper such as varganized paper and glassine paper can be used. The thickness of the paper substrate can be about 0.1 to 1.2 mm, preferably about 0.3 to 1.0 mm. If the thickness of the paper substrate is less than 0.1 mm, the strength (particularly, stiffness) as the substrate is insufficient, and the cut portion 1
If 0 is formed integrally with the cutting plate 6, the sawtooth may be broken, which is not preferable. On the other hand, if the thickness of the paper substrate exceeds 1.2 mm, the piercing property of the cutting portion 10 into the long body of the sawtooth becomes insufficient, and good cutting property cannot be obtained. The paper substrate may be formed by bonding two or more kinds of the above paper materials.

When the storage box of the present invention is prepared using the above-mentioned blank 11, it can be assembled, for example, as follows. First, the auxiliary plate 8 is connected to the protection plate 7 by a broken line e.
Of the bottom plate 2, front plate 3, rear plate 4, top cover 5, front cover 6, side plate 2a,
3a, 4a, 5a, 6a, side plates 2a ', 3a', 4a
, 5a ', 6a' to be polygonal lines a, b, c, d, e,
f, f ', bent to the back side of the blank, and the back side of the cutting plate 9 and the back side of the front lid 6 are fixed with an adhesive A1,
The surface of the auxiliary plate 8 is detachably adhered to the surface of the front plate 3 with an adhesive A2. The bonding between the auxiliary plate 8 and the front plate 3 is usually performed at several spots. Next, with the roll R placed inside, the side plates 2a, 3a, 4a,
, 3a ', 4a' are fixed to each other, and the side plates 5a,
6a, the side plates 5a ', 6a' are fixed to each other.

When the storage box 1 (FIG. 1) prepared by assembling the blank 11 as described above is used by opening, first, the protective plate 7 and the auxiliary plate 8 are peeled off from the front plate 3 while being cut off. Remove the protection plate 7 and the auxiliary plate 8 along A. The jumper B is easily cut in a bridge shape connecting the auxiliary plate 8 and the cutting plate 9, and since the auxiliary plate 8 is detachably adhered to the surface of the front plate 3 as described above,
One end of the protection plate 7 and the auxiliary plate 8 is gripped and a cut line A
Can be easily removed by pulling along. When the protection plate 7 and the auxiliary plate 8 are removed in this way, the cut portion 10 covered by the protection plate 7 is exposed. That is, as described above, the width of the front cover 6 (the distance from the broken line d to the cutting line A) is smaller than the width of the cutting plate 6. As described above, the storage box 1 of the present invention includes the protection plate 7 and the auxiliary plate 8.
It can be opened by the operation of removing.

FIG. 3 is a longitudinal sectional view showing the state of the storage box of the present invention after such opening, and FIG. 4 is a perspective view showing the storage box of the present invention with the upper lid 5 opened slightly. after opening,
The upper cover 5 is rotatable about the broken line c so that the opening can be opened and closed, and the cutting plate 9 is integrated with the front cover 6 and is separated from and connected to the front plate 3 as the upper cover 5 rotates. It becomes possible.

As described above, since the cutting plate 9 is integrated with the front lid 6 in a fixed state, and the cutting portion 10 protrudes from the front lid 6, as shown in FIG. The elongate body can be cut by pulling out the elongate body for a predetermined length and bringing the elongate body into contact with the cutting section 10 and pulling the elongate body upward or moving the storage box 1 downward. At that time, the cutting plate 9 is reinforced by the front lid 6 and has a small deformation when cutting the long body, so that the long body is easily cut. Further, since the durability is high, the cutting of the elongated body as described above can be repeatedly performed.

Examples of the long body applicable to the storage box of the present invention include resin films such as polyethylene resin, polyester resin, vinylidene chloride resin, polymethylpentene, metal foil such as aluminum foil, glassine paper, and wax. Paper, water-absorbing paper, and paper such as oil-absorbing paper can be used.

In the example shown in FIG. 2, the ridge line formed by the vertices of the sawtooth shape of the cutting portion 10 forms a straight line. However, the present invention is not limited to this, and may have any shape. For example, a V-shape with a central portion protruding may be used. Regardless of the shape of the ridge line, in the state where the cutting plate 9 is fixed to the front lid 6 and the cutting portion 10 protrudes from the front lid 6 as described above, it does not hinder cutting of the elongated body. It is advantageous from the viewpoint of durability that the cutting width of the cut portion 10 is small as long as the protrusion does not occur. Therefore, the cut line A is
Preferably, the shape corresponds to the shape of the ridgeline.

Next, the cutting section 10 constituting the storage box 1 of the present invention will be described. The cutting portion 10 has a sawtooth shape as described above, and is formed at the end of the cutting plate 9 on the auxiliary plate 8 side. By opening, the auxiliary plate 8 and the protection plate 7 are removed, and at the same time, the saw-tooth-shaped cut portion 10 of the cutting plate 9 appears in a state protruding from the front lid 6. Auxiliary plate 8 and cutting plate 9
Is connected by a bridge-shaped jumpsuit B so that the cutting line B is not cut off before assembling or using the storage box 1 and cut off when opened. After cutting at the portion of the jumper B, so that the cutting effect of the saw blade of the cutting portion 10 is not hindered,
As shown in the figure, the shape of the jumpsuit B is set so as to cut off at the sawtooth-shaped valleys of the cutting portion 10. The cutting portion 10 is formed not at the end of the blank 11 but at the end of the cutting plate 9 on the auxiliary plate 8 side, and the cutting plate 9 is connected to the auxiliary plate 8 by a bridge-shaped jumper B. 10 is exposed in a blank state, resin can be applied to this portion, and the resin is also applied to the tip of the sawtooth shape.

A water-resistant resin may be applied to the cut plate 9 where the cut portion 10 is formed, in order to impart water resistance.
Examples of the water-resistant resin include a polyester resin, an acrylic resin, a vinyl chloride resin, a vinyl chloride-vinyl acetate copolymer, a polyvinyl alcohol resin, a polyvinyl butyral, a styrene resin, an epoxy resin, a polyurethane resin, and a cellulose resin. Resins, phenolic resins, xylene resins, urea resins, melamine resins, terpene resins, ketone resins, amide resins, silicon resins and the like can be mentioned.

Further, in order to enhance the cutting effect of the cutting portion 10, a hardening treatment by impregnation and hardening of resin may be applied to the cut plate 9 where the cutting portion 10 is formed. This curing treatment is performed by cutting the styrene-butadiene copolymer-based resin, acrylonitrile-butadiene copolymer-based resin, acrylic resin, methyl methacrylate-butadiene copolymer-based resin, chloroprene copolymer-based resin, acryl-vinyl acetate copolymer in the cut portion 10. It can be carried out by coating and impregnating one or more resins such as a system resin and a resin such as paraffin wax. Alternatively, an ultraviolet curable resin may be applied and cured by ultraviolet light.

A method of applying a water-resistant resin for imparting water resistance to a portion where the cutting portion 10 is formed on the cutting plate 9 and applying a resin for curing treatment for enhancing the cutting effect of the cutting portion 10 are as follows. First, the cutting unit 10 is placed in a planar state.
A method of applying and impregnating a water-resistant resin for imparting water resistance or a resin for curing treatment to the position of the second step. Second, the cutting plate 9 is bent to expose the cut portion 10, and the exposed cut portion is exposed. There is a method of coating and impregnating 10 with a water-resistant resin for imparting water resistance or a resin for curing treatment. In any of the methods, since the cut portion 10 is exposed in the blank 11 and is in a closed state, the resin impregnation spreads to the end of the cut portion 10 and the cutting effect of the cut portion 10 is enhanced.

[0023]

As described in detail above, according to the present invention,
A front plate and a protection plate are used as members for preventing the cut portion from being in contact with the roll-shaped elongated body that is contained, and for preventing the cut portion from being contaminated or damaged. Since the protective plate and auxiliary plate are removed during use, the amount of paper base material used for the blank is smaller than that of the conventional storage box, and it is easy to manufacture. The opening operation is only removal of the protection plate and the auxiliary plate, the operation is simple, and since the cutting plate is reinforced by the front lid, the durability and cutting performance of the cutting portion are good,
In addition, since the ends of the constituent members are not exposed at the longitudinal portion of the storage box that can be touched during use, there is an effect that the appearance and the handling feeling are good. Further, when the cut portion is reinforced with resin, the cut portion is exposed in a blank state, so that the cut portion is easily impregnated with the resin, and the resin spreads over the end portion of the cut portion to enhance the cutting effect.
