Abstract
A device for opening sealed food bags is mounted on the frame of an electric can opener. The device includes a serrated cutter wheel which is driven by the can opener motor. A guide surface on the frame guides the bag as it is being fed through the cutter wheel. A modified form of the invention includes a pair of idler discs which overlap the cutter wheel. In a third form of the invention, the cutter wheel is not driven, and a pivotal lever is used to maintain the bag against the cutter wheel as it is fed manually through the cutting mechanism.
