Plate with opening aid for cans

A plate structure with an opening aid for a can having a lever that is attached to the can with a rivet, said plate structure comprising:

• a plate having an upper face and a lower face, a central edge and a radial edge, and
• two lateral edges that each connect a respective end of the central edge and a respective end of the radial edge,
• wherein the radial edge of the plate is curved with a curvature approximating a sphere of curvature having a curvature center that lies approximately on a longitudinal axis of the can and downward from the lower face,
• wherein the radial edge extends over a partial circle with an angle of at least 150°,
• wherein the central edge provides a receptacle configured to receive the rivet,
• each of the lateral edges having a respective edge reinforcement thereon, wherein the edge reinforcements brace the plate, and
• the radial edge has a groove anchor thereon,
• wherein the groove anchor forms an angled slide rail that is directed away from the lower face and engages in a groove of the can,
• the upper face having at least one elongate, substantially crescent-shaped upwardly projecting elevation thereon,
• wherein the elevation is configured to engage with the lever of the can and serves as the opening aid,
• wherein the elevation has ends and a decreasing inclination towards each of the ends thereof, the elevation extending generally concentrically to the receptacle and being at least 5 mm long, and
• at least one sliding aid is arranged on the upper face, wherein the sliding aid has at least one knob,
• wherein the lateral edges have corners that each form a respective projection in a radial direction towards the radial edge and form corner horns, and
• wherein the plate is made of metal.
