Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutter knife with a width cutting tool provided with a cutting knife.

[0002]

2. Description of the Related Art A conventional cutter knife with a width cutter has a fixed cutting width type in which a width cutting plate is fixed to a cutter body with a screw, and a slide fixed to a cutter body with a screw.
There was a variable cutting width type in which the width cutting plate was fixed to the slide with screws.

[0003]

When a conventional cutter knife with a width cutter is used to break off a worn edge along a cutting line or to use it as a normal cutter knife, it is necessary to turn the screw and remove the blade. It was necessary to remove the patch plate, and it took time to attach and detach the width cutting tool.

[0004] Further, since the shape of the cutter knife is suitable for width cutting, it is difficult to use it as a normal cutter knife.

[0005] Further, the cutting width cannot be changed with a fixed cutting width type cutter knife with a width cutting tool. On the other hand, with a variable cutting width type cutting knife with a width cutting tool, the mounting position of the width cutting plate is set to a required cutting width. It had to be adjusted accordingly.

Further, conventional cutter knives with a width cutter are too large and expensive to disassemble a paper pack such as a milk pack or to open a thick tea envelope.

[0007] In addition, small cutter knives are often used to disassemble paper packs such as milk packs, but it is difficult to cut the corners of the paper pack straight.
They could bend or the blades could slip and hurt the desk, floor, or human body.

According to the present invention, the width cutting device can be easily attached and detached,
An object of the present invention is to provide a small and inexpensive cutter knife with a width cutting tool that is easy to use as a normal cutter knife when width cutting is not performed, and that can easily change the cutting width.

[0009]

Means for Solving the Problems In order to achieve the above object, a cutter knife with a width cutter according to the present invention comprises:
At the end of a cutter knife having a cutter blade and a cutter body having a groove for sliding the cutter blade and a slider connected to the cutter blade, a width cutting plate and a fitting concave portion fixed to the width cutting plate are provided. The width cutting tool provided is fitted.

[0010] The width cutting plate and the fitting recess can be made of metal, but if they are integrally formed of synthetic resin, it is inexpensive, and the fitting recess can be formed according to the shape of the cutter knife. The part and the engaging part can be molded at the same time, the width cutting tool can be shaped into a character or an animal, the company name, a logo mark or an advertisement can be molded at the same time, and coloring is easy.

Although the width of the width cutting plate can be asymmetrical for right-handed or left-handed use only, the width of the width-cutting plate can be made symmetrical because the cutter knife is for both right-handed and left-handed use. Right-handed and left-handed can also be used as a knife. In addition, if the shape of the width-applying plate is made to be a shape close to a circle, it will not be caught around when working or carrying around, and it is easy to make the shape of a character or an animal.

The cross-sectional shape of the fitting recess can be rectangular or C-shaped. In the case of the rectangular shape, it is necessary to cut out a portion that interferes with the slider.

The gap between the width patch plate and the cutter blade, that is, the cutting width, can be manufactured according to each application. However, in the case of disassembling a paper pack such as a milk pack, a cutting width of about 3 mm and the side of the paper pack are required. The bottom can be cut open. In the case of opening a thick brown envelope, it can be opened with a cutting width of 2 mm to 3 mm.

[0014] A cutter knife with a width cutter which can be used for both right-handed and left-handed use if the cutting width is changed by providing fitting recesses on the front and back surfaces of the symmetrical width cutting plate. Becomes

In a width cutting tool exclusively for right-handed or left-handed use, a cutting edge stopper can be provided on the width cutting tool, and the back side of the tip of the cutter blade hits this cutting edge stopper so that the cutting edge does not come out any more.

The fitting of the cutter knife and the width cutting tool may cause the width cutting tool to fall off. Therefore, it is preferable to provide the engaging portions A and B on the cutter knife and the width cutting tool, respectively. Considering the ease of use of the cutter knife alone, an engaging portion B composed of a leaf spring made of synthetic resin and a convex or concave portion at its end is provided on the width cutting tool, and the concave or convex engaging portion A is provided on the cutter knife. In this case, the engaging portion A and the engaging portion B may be engaged.

The storage can be facilitated by forming a through hole in the width cutting plate to form a hanging hole, or by attaching a magnet to the back surface of the cutter knife.

[0018]

In the above construction, the width cutting tool is fitted to the cutter body, and the cutting edge of the cutter blade is appropriately extended from the width cutting tool.
If the width cutting plate is applied to the end face of the width-cut object and the cutter body is pulled toward the front while being pressed against the width-cut object, the width can be cut at a constant width.

If the same operation is performed by replacing the gap between the width-applying plate and the cutter blade, that is, the width-cutting tool having a different cutting width, it is possible to cut the width with different cutting widths.
In a width cutting device having different widths for cutting on the front and back sides, in which fitting recesses are provided on both front and back surfaces of the width cutting plate, width cutting with different cutting widths can be performed by mounting the width cutting device upside down.

When used as a normal cutter knife, the width cutter can be easily removed by grasping the cutter knife and pushing out the width cutter with the thumb.
