On a can body (1), comprising a can casing (3), which is closed around the can axis and comprises a metal layer, and a closure part (13, 33, 56), which comprises a metal layer, a laser connection is produced between the metal layers of the can casing (3) and the closure part (13, 33, 56) in an overlapping region of the closure part (13, 33, 56) and the can casing (3). The laser connection comprises a plurality of perforations along the connecting line, or a plurality of narrowly delimited regions, in which the two metal layers are melted together. A plastic material (3b, 7a, 13d, 15, 54, 58) is arranged on the laser connection. The laser connection ensures stability, and the plastic material (3b, 7a, 13d, 15, 54, 58) ensures leak tightness, of the connection between the can casing (3) and closure part (13, 33, 56).

The invention relates to a container having a head piece (7), which container can be or is filled with a medium and is produced of plastic materials using a blow molding, filling, and sealing method, comprising a transition region (13) between the container (1) and at least one first type of a head surface (11), which is arranged on the head piece (7) at an end face and can be penetrated by means of a piercing or cutting part and extends with a specifiable curvature. Said container is characterized in that at least one second type of a head surface (41), which likewise has a specifiable curvature, which is the same as the curvature of the head surface (39) of the first type, but preferably is different therefrom, is present on the head piece (7), that the head surfaces transition into each other in such a way that a whole surface is formed, which spans the free end of the transition region (13) directed away from the container (1), and that the head piece (7) is an integral component of the container (1).

A process for producing a canned product comprises the steps of: providing a can (1), a lid (2) and contents to be filled in the can (1), the can (1) having a mouth (13), and the lid (2) having an extension (21) that is able to fit the mouth (13) to seal the can (1); filling the can (1) with the contents; fitting the lid (2) in the mouth (13) of the can (1), such that the extension (21) of the lid (2) forms a fit with a sidewall (11) of the mouth (13). The process further comprises the step of forming at least one bulge (22) on one of the extension (21) of the lid (2) and the sidewall (11) of the mouth (13) after fitting the lid (2) in the mouth (13) of the can (1), wherein while the lid (2) is removed from the can (1), the convex surface of the at least one bulge (22) is engaged with the other of the extension (21) of the lid (2) and the sidewall (11) of the mouth (13) in such a way that the extension (21) and/or the sidewall (11) is destroyed. A canned product produced by the process is also disclosed.
