1. 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.

Abstract
A spill-resistant beverage container having a liquid freshness detector and notification device is described. The spill-resistant beverage container is comprised of cup, a beverage temperature sensor, a processing electronic circuit and a display device. The temperature sensor and processing electrical circuit are mounted within an enclosure on the bottom of the cup and the display device emits light or sound when the beverage temperature does not have a desired value.

7. A method for determining a freshness of a beverage contained inside a children'"'"'s drinking cup, the method comprising the steps of:
-
incorporating an electrical circuit into the children'"'"'s drinking cup; detecting the physical movement of said cup; controlling said detecting of movement by activating a switch; ignoring the controlling said detecting of movement step by activating a switch unless the switch has been activated for an extended period of time; monitoring the time the cup has not been moved; comparing said time to one or more reference times; and displaying the results of the comparing step as a notification of the freshness of said beverage. - View Dependent Claims (8, 9, 10)

11. A cup with a liquid freshness notifier comprising:
-
a spill-resistant lid having a child'"'"'s drinking spout containing a self sealing outlet valve; a battery for powering said freshness notifier; a timing circuit; a switch for activating said timing circuit; a sensor for sensing when said cup is physically moved; and an indicator to indicate that a desired length of time has been exceeded since the activation of said timing circuit and/or since said cup has been moved, wherein said desired length of time indicates the freshness of said beverage; and a switch inhibit means that prevents said timing circuit from being reactivated before said length of time has passed unless said switch is continually activated for an extended period of time. - View Dependent Claims (12, 13, 14)

15. A beverage container having a beverage freshness notification apparatus, the beverage container comprising:
-
a cup with an opening for filling or removing a beverage from the cavity of the cup, the cup further having sides and a bottom wherein the bottom and sides have an inside surfaces and an outside surfaces; a motion sensor for sensing when said cup is physically moved; a timing circuit; a switch for activating said timing circuit; a switch inhibit means that prevents said timing circuit from being reactivated before a desired length of time has passed unless said switch is continually activated for an extended period of time; a battery for powering said freshness notification apparatus; a thermal sensor coupled to the bottom outside surface of the cup; a comparator coupled to the thermal sensor for comparing the output of the sensor to desired temperature values; and a display device exhibits beverage temperature freshness information in response to an output from the comparator, the motion sensor, and the timing circuit. - View Dependent Claims (16)
