Abstract
A splash and spill resistant insulating lid for beverage containers comprising an insulated splash and spill barrier integrated into a cup lid combination. This is achieved by creating a barrier and/or labyrinth flow path, which buffers and deflects sloshing liquid. Accidental/incidental release of liquid is minimized and/or prevented while allowing the normal flow of liquid for drinking. These features of the SSRIL further create an insulating barrier to keep a cup's fluid hotter or cooler for a longer period of time, enhanced by using an appropriate insulating material combined with finite number of transfer holes that are of a specific shape and/or specific location and/or specific orientation to promote the formation of a surface tension film of fluid across the transfer holes, creating additional barriers against the escape and exchange of both fluid and vapor outside the cup.
