Abstract: In a locking mechanism, in particular, for fixing filter holders on sterilizing containers, with a housing in which a locking member is displaceable between two end positions, namely a first end position in which it engages behind a locking projection, and a second end position in which it releases the locking projection, with a spring means which biases the locking member in the direction towards the first end position, and with an actuating member protruding from the housing for displacement of the locking member, in order to ensure that unlocking does not occur if the actuating member is unintentionally actuated, it is suggested that a second actuating member be provided and that the actuating members be arranged on the housing on opposite sides thereof and be actuatable by displacement in the direction towards the respective other actuating member, the locking mechanism only being unlockable if both actuating members are actuated.

Abstract: A metal closure for beverage containers of the type having a center panel, a center-panel ring, an inner leg, and a pull-tab opener, includes circumferential variegations for increasing the buckling pressure of the container. The circumferential variegations are cold-worked or coined into the center-panel ring and/or into portions of the closure that are adjacent to the center-panel ring. The circumferential variegations include coined surfaces with variegated lengths, variegated coin angles, variegated coin residuals, variegated spaces between coined surfaces, or variegated widths of the center panel. The circumferential variegations achieve non-axisymmetric doming of the metal closure and increase the buckling pressure of the closure by obviating excess metal in the center panel that typically results from scorning the center panel for the easy open end.
