Abstract: A sip and pour drinking system with one or more of a lid, straw assembly, and drinking container with tiers so that a user can: (1) open a first tier and sip a liquid from the container in a first configuration; and (2) open a second tier and pour a liquid from the drinking container in a second configuration. The lid body or base (representing a third tier) has a spout with first and second openings, the latter to retain a straw assembly with a mouthpiece configured to stop and bypass the first opening in the first configuration (for sipping) and unstop the first opening in the second configuration (for pouring). The drinking system also has structures and features for mitigating container pressure, including the first cover opening only slightly through a pushbutton latch assembly that opens the first cover in stages.

Abstract: A container lid system having a lid body with a drinking aperture, a slider aperture and slider, and a recess located on the underside of the lid body. The slider slides within the slider aperture between a first position covering the drinking aperture and a second position exposing the drinking aperture. Slider may be an assembly with first, second, and third slider members that releasably attach to each other via a post in the first member that extends through the slider aperture and second slider member, with the third slider member attaching to the post and retaining the assembly. Venting functionality is achieved by the slider assembly forming a vent channel with the recess on the underside of the lid body when the slider moves towards the open position. Some versions omit the lid body bottom recess and venting functionality or include a matching container.
