A self-opening can comprising:

• a container having a receiving space and a longitudinal wall surrounding said receiving space, said wall having an edge extending around one end of said receiving space;
• a rim member having an outer peripheral portion sealingly joined to said edge, and an inner peripheral portion extending inwardly of said outer peripheral portion and confining an opening for access to said receiving space, said inner peripheral portion having a groove extending around said opening;
• a filler of non-metallic plastic material filling said groove and exposed from said groove;
• a cover panel closing said opening and extending to said inner peripheral portion of said rim member, said cover panel having a layer of non-metallic plastic material connected sealingly to said filler;
• and
• an opening tab having a connecting part connected to said cover panel, and a handle part extending from said connecting part;
• wherein said rim member further includes an intermediate portion extending between said inner and outer peripheral portions, said outer peripheral portion abutting against said longitudinal wall, said intermediate portion projecting transversely and inwardly from said longitudinal wall, said inner peripheral portion being bent from said intermediate portion to project longitudinally and inwardly so as to form a tubular portion which define said opening, said inner peripheral portion being further bent transversely and inwardly from said tubular portion to make a U-turn so as to form said groove.
