Abstract: A nursing bottle bottle is provided with a detachable case mounted to the bottom of the bottle. The bottom of the bottle is provided with a dent. Elastic means suporting a thermosensor is disposed within the case wherein when the detachable case is mounted to the bottom of the bottle, the elastic means pushes the thermosensor upward into close contact with the dent for measuring the temperature of a liquid within the bottle.

Abstract: A nursing bottle is provided with a detachable case mounted to the bottom of the bottle. A temperature sensor is mounted in the case for measuring the temperature of a liquid in the bottle and for providing a temperature signal which is processed by an electronic circuit which is also located in the case. The electronic circuit provides an alarm signal responsive to a predetermined temperature which activates an alarm means. The temperature sensor is suitably mounted by an elastic body which resiliently forces the temperature sensor into contact with the bottom of the nursing bottle. The electronic circuit suitably includes a one chip microprocessor for processing the temperature signal.
