DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet distributing case which is used by cutting various sheets such as synthetic resin wrap film, aluminum foil, kitchen paper sheet and the like used for food packaging into a desired length. In particular, the present invention relates to a sheet distributing case capable of easily separating a cutting member from a case after use.

[0002]

FIG. 8 is a perspective view showing a conventional wrap film distribution case. This conventional example is disclosed in, for example,
It is of the same kind as that disclosed in JP-A-45349. In the wrap film distribution case shown in FIG. 8, reference numeral 1 denotes a rectangular parallelepiped paper box, in which the wrap film W wound in a cylindrical shape on the peripheral surface of the core is housed. On the back plate 2 of the box 1, a cover plate 4 that covers the opening 3 is provided so as to be freely undulated. Furthermore, this lid plate 4
A cover piece 6 overlapping with the front side plate 5 is provided at the tip of the cover member. A metal cutting member 7 is attached to the back side of the tip of the cover piece 6 by means such as caulking or bonding. The cutting member 7 has a saw tooth at the tip, and the saw tooth slightly protrudes from the tip of the cover piece 6.

[0003]

In this type of dispensing case, since a metal cutting member is attached to a paper box, the dispensing case is not used when the wrap film is used up or when the paper is recycled. However, there is an environmental problem that the metal cutting member must be separated and disposed separately.
However, in the conventional example of FIG. 8, since there is no work for peeling off the cutting member 7 attached to the back side of the cover piece 6, it is not easy to actually peel off the cutting member 7 from the cover piece 6. A finger or the like may be damaged by the saw teeth formed on the member 7.

In Japanese Utility Model Laid-Open Publication No. 56-20786, a cutting member made of paper or synthetic paper is used in order to facilitate collection and recycling of used cases. However, a cutting member formed of paper or synthetic paper is not practical because it does not have sufficient sharpness and durability for a wrap film or the like as compared with a metal member. In addition, there has been proposed an improvement method of impregnating a resin material or the like in order to improve the sharpness of the paper cutting member. Since the paper cannot be processed together with the paper material, it is necessary to separate the case and the cutting member.

In order to make the cutting member easy to separate from the case, for example, in a distribution case shown in FIG.
A method is also conceivable in which a perforation is formed horizontally at the base (portion indicated by A) of the cover piece 6, and the cover piece 6 is separated from the perforation from the perforation in an integrated state with the cutting member 7 after use. In this method, the cutting member 7 can be relatively easily and safely separated from the case.

However, since the perforations in this case must be formed along the entire length of the cutting member 7 or so as to surround the entire cutting member, the cover piece on which the cutting member 7 is supported by the perforations is required. 6, the strength (rigidity) of the parts such as 6 is reduced, and the pressing force when cutting the wrap film or the like cannot be increased by the cutting member 7, and if the cover member 6 is strongly pressed, the cover piece 6 bends at the position of the perforation. As a result, there is a problem that film cutting is not successful. Further, since paper remains on the separated cutting member side, the processing of this paper poses a new problem.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and enables a cutting member attached to the tip of a cover piece to be easily separated from a case so that disposal after use can be made extremely practical. The purpose of the present invention is to provide a sheet distributing case which is made in the following manner.

[0008]

According to the present invention, there is provided a box-shaped case body in which a sheet is stored, a cover plate connected to the case body and closing an opening of the case body, and a cover plate. A cover piece that is connected to the front end of the cover body and overlaps the front side plate of the case body; a cutting member attached to the back side of the front end of the cover cover piece; In the sheet distributing case having the opening piece, a separating piece extending from the boundary with the opening piece to the inside of the covering piece is formed on the cover piece through a perforation, and the opening piece is covered with the covering piece. And the separation piece is separated from the cover piece, thereby forming a notch at the tip of the cover piece to expose the end of the cutting member.

In the above means, the separation piece is integral with the opening piece, and the separation piece is separated from the cover piece and at the same time the separation piece is removed from the cover piece to form a notch.

[0010]

In the above-mentioned means, in the state before opening in which the opening piece connected to the cover piece through the perforation is bonded to the front side plate, a cutout is not formed at the tip of the cover piece and the cutting member is exposed. do not do. By separating the opening piece from the lid piece for opening the case, the separation piece provided at the tip of the cover piece can be removed from the cover piece. That is, by removing the separating piece from the cover piece after separating the opening piece from the cover piece, or by separating the separating piece integral with the opening piece from the cover piece together with the opening piece, the end of the cutting member is attached to the tip of the cover piece. A notch is formed to expose the portion. By holding and peeling off the end of the cutting member through this notch,
The cutting member is separated from the cover piece.

[0011] By gripping the cutting member through the notch formed in the case in this manner, the cutting member can be reliably peeled off the case without damaging the finger with teeth. In particular, in a portion to be gripped through the notch, the risk of damaging the finger is reduced by not providing the cutting member with teeth. Further, since the cutout is formed only in the portion corresponding to the edge of the cutting member, the strength of the cover piece to which the cutting member is attached does not decrease.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a state before opening a distribution case of wrap film as one embodiment of the present invention, and FIG. 2 is a perspective view showing a state after opening of a distribution case of wrap film shown in FIG. The box body 10 of this distribution case is

The box body 10, the cover plate 17, the cover piece 18, the side cover piece 19 and the opening piece 31 integral therewith are all made of cardboard. A perforation 32 is formed at the boundary between the cover piece 18 and the opening piece 31. Before the case is opened, the back surface of the opening piece 31 is adhered and sealed to the front surface of the front side plate 12 of the box body 10 by spot gluing (not shown) at several places (FIG. 1).
reference).

The perforations 32 are arranged in a substantially V-shape. When the opening piece 31 is peeled off from the front side plate 12 while being separated from the cover piece 18 by the perforation 32, a V-shaped edge 18a is formed on the cover piece 18 as a perforation separation line. Edge 1 of this cover piece 18
Along 8a, a cutting member 20 having a saw tooth 20a on its back surface is attached so as to slightly project from the edge 18a. Further, separation pieces 31a projecting toward the cover piece 18 are formed at both ends of the opening piece 31, and the separation piece 31a and the cover piece 18
The second or perforated line 32 can be separated from each other by a cutting line. When the separation piece 31 a is cut out together with the opening piece 31, a notch 18 b that exposes both ends of the cutting member 20 is formed in the cover piece 18.

The notch 18b is not necessarily provided with the cover 1
8 may not be formed at both ends, but may be formed only on one of the right and left sides. This notch 18b
This is for making it easier to separate the cutting member 20 from the cover piece 18 after use, and the portion of the cover piece 18 where the notch 18b is formed is a portion that can sandwich the end of the cutting member 20. The cutting member 2 may be located at any position.
It is preferable that the edge of 0 is formed so as to be exposed in the notch 18b. However, the edge of the cutting member 20 does not necessarily need to be exposed in the notch 18b. Further, the notch 18b may be formed to have a width that allows the user's finger to hold the cutting member, for example, 5 mm to 2 mm.
It is preferable to form the notch 18b having a width of about 0 mm.

As shown in FIGS. 3 and 4, the cutting member 20 is mounted on the back side along the V-shaped edge 18a of the cover piece 18 with the saw teeth 20a facing downward. Then, both ends of the cutting member 20 are exposed by the notch portions 18b. In the embodiment shown in FIGS. 3 and 4, the edge 20c of the cutting member 20 extends to the side edge 18c of the cover piece 18, but the edge 20c is located in the cutout 18b. May be arranged. Such an arrangement is particularly useful when the cutting member 20 is spirally rolled and removed using a tool described later.

As shown in FIG. 5A, the cutting member 2
In the case of No. 0, the saw tooth 20a and the caulking piece 33 are formed by press-punching a metal plate. The caulking piece 33 is bent and raised from the cutting member 20 after being punched. As shown in FIG. 5B, the caulking piece 33 is
The cutting member 20 is attached to the cover piece 18 such that the cutting member 20 can be peeled off. The attachment strength of the cutting member 20 to the cover piece 18 is such that the attachment strength enough to cut the wrap film W is maintained and the cutting member 20 can be peeled off the cover piece 18 relatively easily. It is necessary to set the attachment strength by appropriately selecting the amount of bending H at the tip of the caulking piece 33 (see FIG. 5A), the formation density of the caulking piece 33, and the like. It is possible.

The caulked portion formed by the caulked piece 33 is connected to both ends of the cutting member 20, that is, the left and right B
It is preferable that the cutting member 20 should not be provided in the range indicated by, and the cutting member 20 should be easily peeled off the cover piece 18 immediately at the portion B. In the illustrated embodiment, the sawtooth 20a is formed over the entire length of the V-shaped edge of the cutting member 20, but the sawtooth 20a is not formed on the cutting member 20 at, for example, a position corresponding to the notch 18b. When peeling the cutting member 20 from the cover piece 18,
There is no danger of the saw tooth 20a hitting the finger and damaging the finger.

Further, a film retaining portion 21 is formed at a position substantially at the center on the left and right of the front surface of the front side plate 12 and covered with the cover piece 18 when the cover plate 17 is closed. The film holding portion 21 is composed of an adhesive portion 21a provided with an adhesive material layer and a resin layer 2 covering the surface thereof in a double circular shape.
1b, so that the wrap film W remaining on the case side after being pulled out and cut is retained in the film holding portion 21 so that the wrap film W can be easily peeled without being broken at the time of next use. Become.

The wrap film W is wound on a core in a cylindrical shape, and the wound film roll 5 is housed in a box body 10. The wrap film W is, for example, a synthetic resin film of vinylidene chloride, vinyl chloride, polyethylene, polypropylene, or butadiene.

According to the wrap film distribution case having the above structure, after the wrap film is used up, the cutting member 2 exposed from the notch portion 18b by the finger f as shown in FIG.
Grab the 0 end. Then, when the cutting member 20 is pulled up in the direction of the arrow (in the back direction of the cover piece), the caulked portion of the cover piece 18 by the caulking piece 33 is separated, and the cutting member 20 can be separated from the cover piece 18. In addition, for example, a tool similar to a canned opening tool such as a corned beef or a tool such as pliers, nippers, or the like is used. It may be separated by winding it up.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above embodiment, the separation piece 31a was cut out together with the opening piece 31 and the notch 18b was formed in the cover piece 18. However, for example, as shown in FIG. And the notch 1
The separation piece 31a may be left at the portion 8b, and after use, the separation piece 31a may be separated and removed at the perforation 32a to form the notch 18b in the cover piece 18. . However, in this case, it is preferable that the cutting member 20 and the separation piece 31a are not fixed by caulking or bonding.

The shape of the cutting member 20 is not limited to the V-shape but may be a straight line. In addition, the material is not limited to metal, and a glued fiber (vulcanized fiber) plate or the like which has high rigidity and can improve the sharpness of the sawtooth can be used. Furthermore, urethane resin, phenol resin, melamine resin, epoxy resin, polystyrene resin, urea resin, polyphenylene sulfide resin, etc. impregnated synthetic resin such as urethane resin, polystyrene resin, etc. The present invention can be implemented even when a cutting member made of a plastic material is used.

The method of attaching the cutting member to the case is not limited to caulking, but may be a fixing method such as bonding. Further, the distribution case according to the present invention is not only suitable for cutting the wrap film W made of synthetic resin, but can be used for cutting various sheets such as aluminum foil and kitchen paper sheets.

[0025]

As described above, according to the present invention, since the cutting member can be easily peeled off from the case and removed, the used case and the cutting member can be easily separated.

A notch for holding the cutting member can be formed in the cover piece when the opening piece is peeled off.
In other words, in the state before opening the case where the opening piece is not removed, a cutout cannot be formed in the cover piece, so that the cutting member cannot perform an operation such that the cover piece is exposed before the case is opened. The appearance of the case is not impaired.

According to a second aspect of the present invention, if the opening piece and the separation piece are integrated and a notch is automatically formed in the cover piece when the opening piece is removed, the notch is formed only by the opening operation. Can be easily folded.
