Abstract
A drinking device adapted for use by young children includes a cap adapted to sealingly cover a drinking cup. The cap has a spout and a mount, and a valve cartridge removably attached to the mount for controlling fluid flow through the spout. The valve cartridge is removable for easy cleaning or replacement, and includes a valve holder that manually, frictionally pressfits into a barrel-shaped mounting flange on the cap. The valve holder includes a grip to facilitate removal of the valve cartridge from the cap. A valve retainer snap-attaches to the valve holder to hold a silicon rubber valve in place on the valve holder. The valve includes a head section with slits that define cooperating valve fingers that cooperate to selectively allow fluid to flow out of the spout or to allow air to flow back into the cup, thus allowing the valve to operate as a single and only valve on the drinking cup.
