Abstract: A self-return teeter tauter lid assembly (10) includes a cap (12), a release lever (14) and a spring (16) operatively coupled thereto. The cap (12) has a self-gripping handle (18), a top face (20), a sip and vent ports (22), (24) integrally formed in the top face (20). The release lever (14) is detachably and pivotally coupled to the cap (12) about pivot points (28), (29) and is moveable between a sealed configuration and an unsealed configuration. The release lever (14) has a thumb pad (26) on first side of the pivot point (28), (29) and a sip and vent plugs (30), (32) on a second side of the pivot points (28), (29). The sip and vent plugs (30), (32) seal the sip and vent ports (22), (24) in the sealed configuration. The spring (16) urges the release lever (14) to the sealed configuration, whereby a user applying force between the thumb pad (26) and the self-gripping handle (18) achieves the unsealed configuration.
