ABSTRACT:
The invention relates to a can opener which removes the lid (E) of a can by cutting through an outer part of the rim (R) of the lid. The can opener comprises two body portions arranged for relative pivotal movement about an axis, one portion carrying a rotary cutting wheel (10) and the other portion carrying a rotary traction wheel (12). The latter is shaped to distort the rim of the can while it is being cut by the cutting wheel whereby the overlapping engagement between the end wall of the can and the side wall of the can is loosened. To distort the rim, the traction wheel includes a portion having a surface adapted to engage, in use, the inner side wall of the rim, the said surface being inclined at an angle greater than the angle of the inclination of the rim with respect to the vertical axis of the can.
