Abstract

A can opener 1 includes a feed gear 27 rotatably attached to a housing 10 with a shaft for engaging with an end seam 80 of a can 8. A lever 30 is rotatably attached to the housing 10, the lever 30 carrying a traction roll 33 and a cutter wheel 34 which are rotatably attached to the lever 30. The traction roll 33 and cutter wheel 34 have an axle 35 and are movable away from the feed gear 27 for allowing the end seam 80 of the can 8 to be engaged with the feed gear 27, and can also be moved toward the feed gear 27 with the lever 30 for clamping and retaining the end seam 80 of the can 8 between the feed gear 27 and cutter wheel 34 and traction roll 34. A rotating device for rotating the feed gear 27 and the can body 8 relative to the housing 10 and lever 30 is also provided. Preferably the rotating means includes a reduction gearing 2, attached to the housing and coupled to the shaft, and a motor 24 with reduced driving speed for driving the feed gear 27 with increased torque.

CAN OPENER
The invention relates to a can opener including a structure for being easily held and operated by the users.
Typical can openers comprise a base having a feed gear or traction roll for engaging with an end seam at a can end of a can body, and a cutter for engaging with and for cutting the end seam at the can end of the can body.
For example, U.S. Patent No. 4,520,567 to Crawford discloses one of the typical power pierce can openers also comprising a feed gear or traction roll disposed on a base for engaging with an end seam at a can end of a can body, and a cutter for engaging with and for cutting the end seam at the can end of the can body.
However, the base includes a large volume that may not be easily held and operated by the users.
It is accordingly an object of the present invention to provide a can opener including a structure for being easily held and operated by the users.
