Patent ID: 7417417

Claim:
A children's drinking cup with a freshness notification system comprising: a spill-resistant lid having a child's drinking spout containing a self-sealing outlet valve; a thermal sensor, coupled to the cup, for sensing the temperature of a cold beverage within the cup; an electrical circuit having a comparator for determining when the sensed temperature is below a threshold value where the threshold value indicates the freshness of said beverage; a battery that is suitable for incorporation into said children's drinking cup for providing power to the electrical circuit; a sensor for detecting the physical movement of the cup and enabling the electrical circuit to become inactive when said cup is not moving and active when said cup is moving; a switch for controlling said electrical circuit; a switch inhibit means that prevents said switch from controlling said electrical circuit unless said switch is continually activated for an extended period of time; and a display device responds to the output of the comparator.
