Kokuyo S&T Co Ltd will release a stapler that pressure-bonds (crimps) paper sheets with metal teeth Oct 22, 2014.
The company's previous staple-less stapler bonds paper sheets by folding them, causing holes in the sheets. On the other hand, the new method, which is called "press lock method," does not make holes.
With the press lock method, when the lever is pressed down, serrated metal teeth sandwich paper sheets to pressure-bond them. The new staple-less stapler can firmly pressure-bond up to about five copy paper sheets. Also, it is possible to separate bonded sheets by rubbing the bonded part with a hard object such as a pen cap.
This time, Kokuyo S&T made improvements to (1) the mechanism of the stapler so that the force pressing down the lever is efficiently transmitted to the teeth and (2) the shape of the teeth so that paper sheets are more firmly bonded.
The price of the new stapler is ¥1,100 (approx US$10.2, excluding tax). The company aims to achieve sales of ¥300 million per year.
