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.
