Document Type and Number:
Japanese Patent JP2001519720
Kind Code:
A
Abstract:
A can end (13) is manufactured by forming an end shell (5) comprising a seaming flange, chuck wall, centre panel and countersink etc. The end shell is converted to an easy open can end by forming a score and raising a rivet on the centre panel, and attaching a tab to the rivet. The end is subsequently reformed by moving the centre panel (9) relative to the seaming flange (7) to raise the centre panel to a height above the level of the seaming flange. The end is secured to a can body which has been filled with product, and then reformed a second time to lower the centre panel (9) to a height below the level of the seaming flange (7), in order to reduce the headspace within the package.
