Abstract

<P>PROBLEM TO BE SOLVED: To provide a safe snap-off blade cutter, which is safe and easy to use. <P>SOLUTION: The renewable blade of a safe snap-off blade cutter can be exchanged by snapping off its tip section therefrom on a line meeting its edge at an obtuse angle to make its edged point obtuse, so that it is safer and also less causes a feeling of danger visually. Because the edged point of the blade is not acute, it is possible to adjust the cutting depth. Moreover, the cutter can cut a straight line neatly along a ruler because the former contacts the latter on longer area to be prevented from deviation. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は替刃の折り方を変えて刃先を鈍角にして切れ味を維持しながら危険性を軽減したカッターナイフに関するものである。The present invention relates to a cutter knife that reduces the risk while changing the way the spare blade is folded to make the edge of the blade obtuse and maintain sharpness.

従来カッターナイフは替刃の先端部が鋭利で危険であった。その上刃先が鋭利であるがため弱くブレるため、切断が思うようにならないことがあった。Conventional cutter knives have a sharp and dangerous tip. In addition, the blade edge is sharp, but it weakly blurs, so cutting may not be as expected.

替刃の刃先を鈍角に折ることによって先端部分が切れないので安全性を増すことができる。従来品は図１のように先端部分が鋭利で、視覚的にも大変危険である。それを図２のように折ることによって先端部分が切れないから突き刺す危険性が少なくなる。又視覚的にも危険性を軽減される。先端部分が切れないことを利用してカット面に対し角度を変えカットするとき深さを調節することができる。それゆえ浅く切ることができ内部を傷つけにくい。刃先が鈍角であるため図３のように添い切りするとき接触面が長くなり刃先がブレにくくなり美しく直線を切ることができる。Since the tip portion is not cut by folding the blade edge of the replaceable blade at an obtuse angle, safety can be increased. As shown in FIG. 1, the conventional product has a sharp tip and is visually dangerous. By folding it as shown in FIG. 2, the tip portion cannot be cut, so that the risk of piercing is reduced. The danger is also reduced visually. The depth can be adjusted when changing the angle with respect to the cut surface using the fact that the tip portion is not cut. Therefore, it can be cut shallowly and the inside is hard to be damaged. Since the cutting edge has an obtuse angle, the contact surface becomes longer and the cutting edge is less likely to be shaken when it is applied as shown in FIG.

本発明は定規でものを添え切りするときとか、モノを削るときに刃先が鋭利でないので安全に切ることができる。The present invention can be cut safely because the cutting edge is not sharp when cutting or cutting things with a ruler.
