<p>The invention relates to an improved can opener which is designed to open a metal container by making a continuous, peripheral cut in the corresponding upper cover of said container. The inventive device is of the type that comprises a pair of interarticulated arms which define a clamp therebetween. According to the invention, one arm is tilted in relation to the other in order to close said clamp and mount the cutting edge on the cover of the container. The aforementioned cover is then cut by rotating a toothed wheel which in turn moves the can opener along the perimeter of the container, the upper edge of the container being disposed between said toothed wheel and a lateral flange of the main arm. The toothed wheel is rotated using a rotation-mounted manual actuation lever or crank handle. Moreover, a ratchet is provided which enables the toothed wheel to rotate continuously and the can opener to move along the perimeter of the container by subjecting the crank handle or lever to an alternating tilt movement. <IMAGE></p> |
