12. In a sterilizing apparatus having in combination a housing of thermally insulating material and a lid, at least first and second heat elements disposed in said housing and operably associated with heat element switch means, a first contoured recess disposed in said first heat element for receiving a first contoured container, a second contoured recess disposed in said second heat element for receiving a second contoured container, said lid cooperating with said heat elements for defining at least first and second sterilizing compartments, the improvement comprising an electric heating system for said compartments, comprising:
-
(a) a pair of recesses disposed in said housing, each of said pair of recesses having one of said heat elements disposed therein; (b) means are associated with said pair of recesses for displaceably supporting said heat elements; (c) each of said heat elements includes a heat conductive element and electrically operable heating means for heating an associated one of said containers; (d) said lid is pivotally connected to said housing and adapted for being pivoted between an open and a closed position; (e) power supply means; (f) first heat element switch means are electrically connected to said power supply means, said first heat element switch means being open when said lid is in said open position and being closed when said lid is in said closed position and said first contoured container is positioned in said first heat element contoured recess; (g) second heat member switch means are electrically connected to said first heat element switch means, said second heat element switch means being open when said lid is in said open position and being closed when said lid is in said closed position and said second contoured container is positioned in said second heat element contoured recess; (h) each of said heat elements is displaced for thereby closing said associated switch means by pivoting of said lid to said closed position when each of said contoured containers is positioned in an associated contoured heat element recess; (i) first timing means are electrically connected to said second heat element switch means; (j) said first heat element is electrically connected to said first timing means for heating said first contoured container to a preselected elevated temperature for a preselected time period; (k) second timing means are electrically connected to said second heat element switch means; (l) said second heat element is electrically connected to said second timing means for heating said second contoured container to a preselected elevated temperature for a second preselected time period; and
,(m) said first heat element and timing means and second heat element and timing means are electrically connected in parallel circuits whereby said first and second heat elements are only operable for energizing said associated heating means when both said first and second heat element switch means are closed. - View Dependent Claims (13, 14, 15, 16, 17)
