ABSTRACT:
A sterilizer for use in sterilizing articles removably received therein, includes first thermal insulating means with a receiving cavity formed therein; cover means including a second thermal insulating means, the cover means being movable with respect to the first means for selectively covering said cavity; heating means received within the cavity and defining recess means for removably receiving therein an article to be sterilized, the heating means having a preselected volume for relatively slowly dissipating heat; and power control means for selectively applying electrical power to the heating means for heating the heating means, and for automatically cutting off the power to the heating means in response to a first predetermined temperature being reached by the heating means, the combination of the heating means and the first and second insulation means resulting in a relatively slow rate of heat loss from the heating means for enabling the temperature of the heating means not to fall below a second predetermined temperature, until a measured period of time elapsed after the electric power has automatically been cut off to the heating means.
