Claim:
A self return lid assembly for selectively sealing a container comprising: a cap having a self-gripping handle, a top face, a sip port and a vent port integrally formed in the top face, and a generally circular outer peripheral rim; a release lever detachably pivotally coupled to said cap about a pivot point and moveable between a sealed configuration and an unsealed configuration, said pivot point being disposed outside said generally circular outer peripheral rim, said release lever having a thumb pad on a first side of the pivot point and a sip plug and a vent plug on a second side of the pivot point, the second side of said release lever is fork-shaped having two arms, wherein the vent plug and the sip plug each extend from the distal end of one of each arm, and the sip plug sealing the sip port independently of the vent plug sealing the vent port in said sealed configuration; and a biasing mechanism operatively coupled to said cap and said release lever, said biasing mechanism urging said release lever to said sealed configuration through application of an upward force on an underside of said release lever, whereby said unsealed configuration is achieved by applying force between the thumb pad and the self-gripping handle.
