Abstract

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.

First claim

What is claimed is:

1. A variable flow cup, comprising:
a cup body having a concave form ending in an upper rim;
a flow cap selectively secured to said upper rim, said flow cap having a circular central panel surrounded by a flow gap through which liquid may flow out of said cup, and further including a set of exterior threads on an outer periphery of said flow cap;
a control ring mounted to said flow cap for selective longitudinal movement between first and second positions, said control ring including an adjustment skirt having threads on an interior thereof which mate with said exterior threads whereby rotation of said control ring relative to said flow cap causes said movement between said first and second positions, said control ring further including an annular plug which seals said flow gap when said control ring is in said first position and which is spaced from said flow gap when said control ring is in said second position, said control ring further including a peripheral drinking rim extending longitudinally outward therefrom, said peripheral drinking rim having a diameter of no less than about 42 mm.

2. A cup as in claim 1 , wherein said control ring is mounted to said flow cap by a threaded connection.

3. A cup as in claim 1 , wherein said flow cap further includes a sealing ring outside of and longitudinally downward from said flow gap, and wherein said control ring further includes a sealing skirt closely surrounding said sealing ring.

4. A cup as in claim 3 , wherein said control ring is mounted to said flow cap by a threaded connection.
