Abstract: An advanced transitional cup (ATC) for training developing children and developmentally-challenged individuals to drink from a cup. The ATC includes a lid with a small fluid aperture and an electric air valve. A microcontroller located in the base of the ATC converts a user-defined “flow rate” into a PWM voltage signal that successively opens and closes the air valve. A higher flow rate results in a PWM signal that opens the air valve for longer spans of time and closes the air valve for shorter spans of time as compared to a lower flow rate, thereby allowing more air to enter the ATC and fluid to be expressed from the fluid aperture more readily. A touch sensor on the sidewall of the ATC prevents the air valve from being opened, and thus fluid from exiting the fluid aperture, unless a drinker is touching the touch sensor, thereby preventing accidental spills.

Abstract: An improved no-spill cup construction and valve assembly. When not in use, an opening in the flexible material rests against a blocking element, sealing off the opening against the flow of liquid. The closed position provides an extremely secure seal against fluid leakage, such that inadvertent spills, such as by turning the cup upside down, are ineffective. The act of sucking at the cup spout creates negative pressure or a partial vacuum against the flexible material, lifting the opening off of the blocking element, and unblocking that opening. When the opening is unblocked, liquid can flow freely through the valve and spout.
