US Patent 11471610 Asymmetrical closure for a medical device

A closure for a medical device includes a base having a terminal end for supporting the base in an upright orientation. A connector is mounted on the base for the attachment to the medical device. Automatic, self-righting capabilities of the closure include a curved, substantially bulbous, exterior surface of the base and a center of mass located between the terminal end and a flange. The flange is connected to the base and includes a multi-level peripheral edge extending outwardly from said base at different distances. An included asymmetrical structure of the closure facilitates the automatic, self-righting capabilities thereof.
