Containers of the open top can type are closed and sealed by a closure system comprising an inner lid of thin material such as plastic film and a stiff outer cover which grips the container and bears down on the inner lid flange to hold it securely in closed, sealing position. Optional provision is made for the escape of air during insertion of the inner lid and retention of the lid in position pending application of the outer cover.
