Keyed straw assembly with dual-engagement architecture

A lid structure for a beverage container, comprising:

• a body portion;
• a connection port disposed on the body portion, the connection port comprising a first guide path and a second guide path positioned on opposite sides of the connection port, wherein each guide path includes a vertical portion configured to receive a straw tab during axial insertion and a horizontal portion configured to secure the straw tab during rotational locking, and wherein the connection port has an increased wall thickness configured to provide resistance to stresses that develop from dual engagement points during repeated locking and unlocking cycles;
• a detent positioned along each guide path, the detent configured to provide a retention feature to secure the straw tab in a locked state;
• a straw fitting positioned within the connection port, the straw fitting comprising a straw opening for fluid communication with a straw;
• and
• a keyed straw assembly comprising a sleeve having a first straw tab configured to engage the first guide path and a second straw tab configured to engage the second guide path, wherein the dual-path engagement distributes locking forces across two discrete locations on the connection port.

A beverage system, comprising:

• a base structure defining an interior volume for containing a beverage;
• and
• a lid structure coupled to the base structure, the lid structure comprising:
• a body portion having a spout portion;
• a connection port disposed on the body portion;
• and
• a keyed straw assembly comprising a straw extending into the interior volume and a sleeve having a first straw tab and a second straw tab positioned on opposite sides of the sleeve, wherein the first straw tab and the second straw tab are configured to engage corresponding guide paths within the connection port to secure the keyed straw assembly to the lid structure, and wherein the dual engagement points resist angular displacement of the keyed straw assembly relative to the lid structure when subjected to lateral forces during use.
