A pivotally mounted frame has a portion which can be moved toward and away from the piston while it is retracted from the metal container and the frame carries two cutting knives and two divaricating members disposed alternately around the piston axis. Each knife and each divaricating means is movable parallel to the axis of the piston and radially outwardly of the piston by a pair of pivotally interconnected fluid-actuable, cylinder and piston assemblies. The frame may also carry apparatus for loading container sealing discs on the press metal container and may be in the form of a cage with an openable side.
