SPILL RESISTANT TRANSITION CUP

A spill resistant cup comprising: a substantially hollow lower body with at top and a bottom, where the bottom of the lower body is closed and the top of the lower body is open; a substantially hollow upper body with a top and a bottom, where the top of the upper body is closed and the bottom of the upper body is open, the open bottom of the upper body corresponds to the open top of the lower body such that the upper body and the lower body together form a single vessel, and the top of the upper body has an opening, where the opening has a smaller diameter than the upper body; and an opening between the lower body and the upper body, where the opening has a smaller diameter than the lower body and the upper body. Fluid in the lower body may travel through the opening between the lower body and the upper body and into the upper body and then may travel through the opening in the top of the upper body when the cup is tipped sufficiently, but the fluid will not exit the cup significantly if the cup merely falls over.
