A training cup for children includes a cup body. A flow cap having an annular flow gap is selectively mounted to the cup body. A control ring is mounted to the flow cap for relative longitudinal movement toward and away from the cup body. The control ring includes an annular plug. In a first position the plug will block the flow gap to prevent flow from the training cup. In a second position the plug is spaced from the flow gap to allow restricted flow from the training cup. An infinite variation of positions and flow restriction are allowed between this first and second position. The control ring includes a drinking rim which has a minimum diameter of approximately 42 mm to force the child to engage the drinking rim with the lips and use it as a cup. |
