Title: Improved can opener actuated by a crank or by an electric gear motor
IPC: B67B7/70
Filed: 1986-01-23
Abstract: The invention relates to a preserve-can opener using a cutting blade 2 and a notched rotary roller 7 moved by a crank. The clamp (staple) of the preserve can is pinched between the blade which penetrates into the inner angle of the lid and the wheel (roller) which bears on the outside of the clamp (staple). The necessary squeezing is generally obtained by the relative flexibility of the blade 2. In order to separate the blade from the wheel (roller), a cam 13 actuated by a lever 14 pushes the inner face of the blade. Since the spindle 6 of the wheel (roller) moves only in rotation on itself, a motorised version is easy to produce. This can opener is more particularly intended for communal catering.
