1. A fail safe sterilizing apparatus for simultaneously sterilizing lenses contained in a lens case and a bottle of rinse solution, comprising:

  • (a) a housing comprised of a thermally insulating material and having a lid displaceable between an open and a closed position;

    (b) a pair of recesses disposed in said housing;

    (c) a first heat element displaceable mounted in a first one of said pair of recesses and including a first contoured recess therein for receiving a first container;

    (d) said first heat element includes a heat conductive element and electrically operable heating means for heating said first container;

    (e) a second heat element displaceably mounted in a second one of said pair of recesses and including a second contoured recess therein for receiving a second container;

    (f) said second heat element includes a heat conductive element and electrically operable heating means for heating said second container;

    (g) said first and said second heat elements being displaced when said first and said second containers are positioned in said associate first and second contoured recesses and said lid is in said closed position;

    (h) switch means are electrically connected with each of said first and second heat elements and are operable only when both said first and second heat elements have been displaced by said closed lid for thereby permitting operation of said associated heating means;

    (i) a control means including an electrical control circuit is electrically connected with said switch means and each of said heating means for simultaneously energizing said heating means; and

    (j) means are electrically connected with said control means for connecting said control means to a source of electric power.
