In at least one embodiment, an inward edge flange with an inserted sealing ring is arranged in the form of a valve seat at the free end of a constricted can neck on a can body. The inward edge flange holds the sealing ring without completely surrounding it, and the sealing ring is therefore accessible from the interior of the can lateral surface. After the crimping of a valve part, an inner stop is formed between the sealing ring and the connecting shell flange. Since the sealing ring is elastic, the connecting shell flange bears against the sealing ring without gaps along the entire circumference. The sealing ring also bears tightly against an inner contact surface of the inward edge flange of the can body.
