Abstract
A container lid is characterized by a flange having reinforcing ribs with their axes disposed non-perpendicularly to said flange. The reinforcing ribs may be relatively thin in comparison to prior art devices and permit an increased flexibility of the flange, providing improved shock absorption capabilities and ease of installation and removal of the lid, and improved automation thereof.
