ABSTRACT:
A device for heating a drink in a thermoplastics container sealed by a metal cover, in which the container is placed in a support upside-down and depressed to bring its cover into contact with an electrical heater, the depression of the container support operating a microswitch which energizes the heater and a support-retaining electromagnet to heat the container for a timed interval. The resistance of the heater is measured during heating by a Wheatstone bridge and utilized to regulate the temperature reached by the heater.
