[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet distributing case for cutting various kinds of sheets such as synthetic resin wrap film, aluminum foil, kitchen paper sheet and the like used for food packaging and the like into a desired length. More particularly, the present invention relates to a sheet distributing case that allows the cutting member to be easily separated from the case after use.

[0002]

2. Description of the Related Art FIG. 7 is a perspective view showing a conventional sheet distribution case for a wrap film. This conventional example is of the same kind as that disclosed in, for example, JP-A-2-45349. In the sheet distribution case shown in FIG. 7, reference numeral 1 denotes a rectangular parallelepiped paper box main body, in which a wrap film W wound in a cylindrical shape on a peripheral surface of a core.
Is stored. On the back plate 2 of the box body 1, a cover plate 4 that covers the opening 3 is continuously provided so as to be openable and closable. Further, a cover piece 6 overlapping the front side plate 5 is provided at the tip of the cover plate 4, and a metal cutting member 7 is provided on the back side of the tip of the cover piece 6 by means such as caulking or bonding. Installed. 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 sheet distributing case, since a metal cutting member 7 is attached to a paper box, it is necessary to dispose of the wrap film or to recycle the paper. At this time, there is an environmental problem that the metal cutting member 7 must be separated and disposed separately. However, in the conventional example of FIG. 7, there is no working portion for grasping with a finger when peeling off the cutting member 7 attached to the back side of the cover piece 6, so that the saw-toothed portion of the cutting member 7 is actually grasped. In this case, the cover member 6 must be peeled off from the cover member 6, so that the operation of removing the cutting member 7 is not easy, and there is a risk that the finger of the cutting member 7 may be damaged by the sawtooth.

An object of the present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a sheet distribution case in which a cutting member attached to the tip of a cover piece can be easily removed.

Further, according to the present invention, when a cut line for removing the cutting member is provided in the cover piece, the strength of the cover piece when cutting the sheet with the cutting member is reduced due to the presence of the cut line. It is an object of the present invention to provide a sheet distribution case capable of preventing the occurrence of the sheet distribution.

[0006]

According to the present invention, a part of a sheet distributing case formed of a paper material or the like is formed as a separation part which can be cut and separated, and this separation part is held by a finger and cut together with the separation part. The member can be removed.

That is, the present invention provides a box body in which a sheet is stored, a cover plate connected to the box body and closing an opening of the box body, and a box body extending from the tip of the cover plate. In a sheet distribution case having a cover piece overlapping the front side plate and a cutting member attached to the back side of the tip of the cover piece, the cover piece is formed with a separation portion that can be cut and separated by a cut line, The cutting member can be removed together with the separation portion, and the cut line is formed at a portion other than the central portion of the cover piece.

According to the invention, in particular, the teeth of the cutting member have a V-shape in which the central part of the cover piece projects in the direction of the bottom plate of the box body, and the cut line is the V of the cutting member at the cover piece. This is effective when it is formed at a portion other than the top of the character shape.

In the above, the cut line is formed along the edge of the cutting member by the cover piece, and the tip portion of the cover piece together with the cutting member can be cut and separated by the cut line as a trigger. Are

Alternatively, the cut line extends to the edge of the tip of the cover piece across the cutting member, and a separation portion that can be cut and separated at the cut line portion is formed at a side end of the cover piece. And
An end portion of the cutting member is fixed to the separating portion, and the caulking portion between the cutting member and the cover piece can be separated by peeling the cutting member together with the separating portion to the back side of the cover piece.

[0011]

According to the present invention, a separating portion which can be separated by a cut line is partially formed in the cover piece, and the tip of the cover piece is cut and separated by using the cut line as a trigger.
A part of the cover piece to which the cutting member is attached can be cut and removed. Alternatively, a part of the cover piece is cut off from the cut line to separate the separation part, and the cutting member together with the separation part is peeled off from the cover piece so that the caulked part of the cover piece and the cutting member can be removed. I have to.

However, since the cut line is formed in a portion other than the central portion of the cover piece, the strength of the cover piece is not reduced by the cut line at the central portion of the cover piece.
When the sheet is cut by the cutting member, the strength of the cover piece necessary for cutting can be secured.

In particular, when the teeth of the cutting member are V-shaped, when the sheet is cut by the cutting member, a large deformation force acts on the cover piece at the V-shaped top. Therefore,
By adopting a structure in which a cut line is not provided in a portion corresponding to the V-shaped top, the strength of the cover piece when cutting the sheet at the V-shaped top can be increased.

It is a synthetic resin film of polypropylene or butadiene.

The sheet distribution case is made of a cardboard material. The box body 10 includes a bottom plate 11, a front side plate 12, a back plate 13, and two end plates 14a and 14b connecting both ends of the bottom plate 11, the front side plate 12, and the back plate 13, and these plate portions are used. It has a cubic shape in which five surfaces are covered and one upper surface is an opening 15. Box body 10
A lid plate 17 extends continuously from the upper edge of the back plate 13. At the front end of the cover plate 17, a cover piece 18 is formed continuously and substantially bent at a right angle. A boundary portion between the back plate 13 and the cover plate 17 is a hinge portion 16 in which a cardboard, which is a material, is folded. Side lid pieces 19a and 19b are bent at substantially right angles on both side ends of the lid plate 17.

FIG. 3 shows one side cover piece 19a and cover piece 18
2 shows a connection structure. A joining piece 21a is bent at a substantially right angle at the right end of the cover piece 18 in the figure, and the joining piece 21a is superimposed on the inside of the side cover piece 19a.
9a and the joining piece 21a are bonded and fixed to each other. Also at the left end in the drawing of the distribution case, a joining piece 21b is bent at the left end of the cover piece 18, and this joining piece 21b is superimposed on the inside of the side cover piece 19b, and both are bonded and fixed. When the opening 15 of the box body 10 is closed by the cover plate 17, the cover piece 18 is overlaid on the outside of the front side plate 12, and the side cover pieces 19a, 19b and the joining pieces 21a, 21b are provided.
Are superimposed on the outside of the end plates 14a and 14b.

As shown in FIG. 1 and FIG.
Is substantially V-shaped. A cutting member 22 is attached to the back side of the cover piece 18 along the edge 18a, and the saw teeth 22a of the cutting member 22 slightly protrude from the edge 18a. The cutting member 22 is formed of a thin iron plate, is provided with a plurality of pairs of crimping claws 22b, and has a substantially V-shape similar to the edge 18a of the cover piece 18. The saw teeth 22a are also arranged in a V-shape. The caulking claw 22b is inserted into the cover piece 18 from the back side and bent at the surface of the cover piece 18, whereby the cutting member 22 is bent.
Is fixed to the cover piece 18 by caulking. As shown in FIG. 1, a film retaining member 23 is provided at a central portion of the front side plate 12 of the box body 10 and at a portion covered by the cover piece 18.

As shown in FIG. 3, a separating portion B for removing the cutting member 22 is constituted by components indicated by B1 to B4. B1 of the separating portion is a part of the side cover piece 19a, and B2 is a part of the joining piece 21a. An arc-shaped perforation 31 cut through both pieces is formed on the side lid piece 19a and the joining piece 21a that are adhered and fixed to each other, and the B1 portion and the B2 portion are adhered to each other by the perforation 31. It can be cut and separated from the side cover piece 19a and the joining piece 21a as it is. At the right end of the cover piece 18, a substantially triangular B3 portion continuous with the B2 portion can be cut and separated by a perforation 32. The cut lines 32a of the perforations 32 are slightly longer and narrower, and can be cut relatively cleanly. The cover piece 18 is provided with a band-shaped B4 portion having a predetermined width along the edge portion 18a, which is continuous with the B3 portion. The B4 portion can be cut and separated from the cover piece 18 by a perforation 33. The perforation 33 is formed along the cutting member 22 formed substantially in a V-shape from the end of the perforation 32.

However, as shown in FIGS. 1 and 2, the perforations 33 are formed only at the portions other than the vicinity of the center, which is the top of the V-shaped cutting member 22, that is, only at the left and right ends of the cover piece 18. Partially formed. The perforations 33 are formed by forming a group of holes made up of short cut fine cut holes 33a at intervals. Since the holes are formed at intervals, the cut is relatively rougher than the perforations 32.

Hereinafter, a method of removing the cutting member according to the first embodiment will be described. In the first embodiment, when the wrap film has been used, the B1 portion and the B2 portion are grasped with a finger, and the B1 portion and the B2 portion are cut and separated from the side cover piece 19a and the joining piece 21a by the perforation 31. I do. If it is pulled forward as it is, the B3 portion and the B4 portion, which are part of the cover piece 18, are gradually cut and separated along the perforations 32 and 33. The perforation 33 is not formed in the vicinity of the center of the cover piece 18, but in the portion where the perforation is not formed, along the edge of the cutting member 22 opposite to the saw tooth 22 a side, the cover piece is formed. The cutting of 18 progresses. Since the cutting member 22 is formed of a metal plate,
When the cutting member 22 is pulled together with the portion and the B4 portion, the cover piece 18 can be easily cut at the edge of the cutting member 22. In the portion where the perforations are not formed, the cutting member 2
As the cutting progresses to the cover piece 18 along the edge of 2,
This cutting joins the perforation 33 formed at the left end of the cover piece 18 in the drawing, and the cover member 1
8 can be reliably cut and separated.

FIG. 4 is a front view of a sheet distribution case showing a second embodiment of the present invention, FIG. 5 is a partial perspective view of the right end thereof,
FIG. 6 is a partial perspective view illustrating the operation of removing the cutting member. In this embodiment, the separating section C is provided only at the right end of the sheet distribution case. This separation part C is C1-C3
It consists of each part shown by. The portion C1 of the separation portion C is the entirety of the side cover piece 19a, and the portion C2 is the entirety of the joining piece 21a. The portion C3 is formed in a triangular shape at the right end of the cover piece 18 continuously with the portion C2. A perforation 35 is formed at the C1 portion, that is, at the bent boundary between the side cover piece 19a and the cover plate 17. C3 is perforated 3
6 allows the cover piece 18 to be cut and separated.

The perforation 36 is continuous with the perforation 35, is formed obliquely by the cover piece 18, and extends to the edge of the tip of the cover piece 18 across the portion where the cutting member 22 is provided. ing. In the second embodiment, a strip-shaped portion along the edge 18a of the cover piece 18 is not included in the separation portion, as in the portion B4 shown in FIG. And triangular C3
In the portion, the right end portion of the cutting member 22 is fixed by the caulking claw 22b in the portion (a).

In the second embodiment, when the wrap film W in the box body 10 has been used, first the C
Part 1 and part C2 (the side lid piece 19a and the bonding piece 21a bonded to each other) are grasped with fingers, and the
And the C3 portion, which is continuous with the C2 portion, is cut and separated from the cover piece 18 by the perforation 36. As shown in FIG. 6, with the cover plate 17 and the cover piece 18 lifted up from the box body 10, the C1, C2 and C3 parts are moved in the direction of the back side of the cover piece 18 and the cover piece 1
8 along the edge 18a. As a result, the swaging claws 22b of the cutting member 22 are sequentially disengaged from the right one to the left one, and the cutting member 22 can be peeled off from the back surface of the cover piece 18.

In this embodiment, the separation part C is composed of the part C1 and the part C2.
After the portion is cut by the perforations 35 and 36, the cutting member 22 is peeled off from the cover piece 18 at the portion of the caulking claw 22b. Therefore, in order to facilitate this peeling, it is preferable to reduce the swaging engagement force by shortening the swaging claw 22b. However, in FIG.
The caulking claw 22b of the portion indicated by the symbol C3 constituting the separation portion C
This part (b) must be firmly fixed to the
It is necessary to increase the fixing strength of the caulking claw 22b in the portion indicated by.

In the first embodiment, a perforation 3 for cutting a B4 portion formed in a band shape at the front end of the cover piece 18 is used.
3 are formed near both ends of the cover piece 18 near the center, and in the second embodiment, the edge 1 of the cover piece 18 is formed.
No perforations along 8a are formed. Since the perforation is not formed at the center of the cover piece 18 where the cutting member 22 is provided, the strength of the portion of the cover piece 18 where the cutting member 22 is provided is maintained high. Can be. In particular, when cutting the wrap film W, since the perforations are not formed at the V-shaped top of the cutting member 22 on which the greatest force acts, the strength of the cover piece 18 at this top is increased. Can be maintained. Therefore, at the time of the cutting operation of the wrap film W, the deformation of the portion provided with the cutting member 22, particularly the deformation at the top of the V-shape is less likely to occur, and the wrap film W can be cut reliably.

In each of the above embodiments, the edge 18a of the cover piece 18 is V-shaped. However, the same is true even if the edge is linear. The sheet is not limited to a wrap film, but may be an aluminum foil or a kitchen paper sheet. Further, the cutting member 22 may be made of not only metal but also plastic material. Further, in each of the above embodiments, the cutting member 22 is fixed to the cover piece 18 by the caulking claw 22b, but the cutting member 22 may be fixed to the cover piece 18 by an adhesive. In this case, FIG.
In the first embodiment shown in FIG. 6, the cutting member 22 is peeled off from the cover piece 18 by peeling off the adhesive portion.

[0027]

According to the present invention, by providing perforations at the ends of the cover pieces, the cutting member can be easily removed from the cover pieces when the sheet distribution case is disposed of. On the other hand, since the perforations are formed only at the ends avoiding the central portion of the cover piece, the strength of the tip portion of the cover piece to which the cutting member is fixed can be maintained high, and when cutting the wrap film, Since deformation and the like hardly occur in the central portion of the cover piece, the wrap film can be reliably cut.
