Abstract

A straw adapter for coupling a straw to a water bottle lid is provided. The straw adapter may receive the straw in a cavity, and a protrusion of the straw adapter may be received by the lid. Retaining rings circumscribing the cavity and the protrusion may provide for frictional coupling. The straw adapter may include a valve comprising a plurality of self-sealing flaps. The self-sealing flaps may be configured to open or close in response to pressure changes. As such, when the self-sealing flaps are oriented vertically, the valve may allow fluid to flow through the straw adapter. Conversely, when the self-sealing flaps are oriented horizontally, the valve may impede fluid from flowing through the straw adapter. Thus, the straw adapter may help to limit unintentional spills.
