Cylindrical or tapered metal container with a pressurised sealing cover and a method and apparatus for the production of such a metal container

摘要

A rim ring (5) which accommodates the pressurised sealing cover is formed integrally on the upper rim of the container shell (B'). The rim ring is formed from the shell material itself and is first of all bent inwards and then downwards. This eliminates the customary joint between the shell of the container and a separately produced ring in the case of known cans or buckets with a pressurised sealing cover. <IMAGE>
