Abstract
A drinking cup having a receptacle with an open end and a lid assembly configured for releasable engagement with the receptacle over the open end. A lid assembly wall has an inner surface and an inner ring extending radially inward therefrom. The inner ring defines a plurality of fluid passages. A seal assembly is configured to be retained by the inner ring, with the seal assembly being resiliently deformable between a sealed configuration and an unsealed configuration. In the sealed configuration, the upper lip sealingly engages the inner surface and fluid is prevented from flowing through a lid assembly volume defined between the lid assembly and the seal assembly. In the open configuration fluid is permitted to flow from the receptacle, through the plurality of fluid passages, and between a gap defined by a portion of the seal lip and a corresponding portion of the sealing surface.
