Abstract
A bottle heater that includes a flexible band member having an inner heating surface adapted to be in contact with the bottle, a releasable retaining member for securing the flexible band member about the outer surface of the bottle and an electrical heating element disposed in the flexible band member for heating the flexible band member and extending over a heating element area. A first thermostat is disposed within the heating element area over the flexible band member for sensing and controlling the temperature of the electric heating element and a second thermostat is disposed within the heating element area spaced from and under the electrical heating element for sensing the temperature of the bottle.
Claims20
A bottle heater comprising:
- a flexible band member having an inner heating surface adapted to be in contact with the bottle;
- a releasable retaining member for securing the flexible band member about the outer surface of the bottle;
- an electrical heating element disposed in the flexible band member for heating the flexible band member and extending over a heating element area;
- a first thermostat disposed within the heating element area over the flexible band member for sensing and controlling the temperature of the electric heating element;
- and
- a second thermostat disposed within the heating element area spaced from and under the electrical heating element for sensing the temperature of the bottle.
A bottle heater comprising:
- a flexible belt having an electrical heating element imbedded therein, an inner heating surface adapted to be in contact with the bottle and means for securing the belt about the bottle;
- a first thermostat disposed within the heating element area over the flexible band member for sensing and controlling the temperature of the electric heating element;
- said first thermostat having a predetermined set point at which the thermostat opens to interrupt power to the heating element;
- a second thermostat disposed within the heating element area under the electrical heating element for sensing the temperature of the bottle;
- said second thermostat having a predetermined set point at which the thermostat opens to interrupt power to the heating element;
- and
- wherein the first thermostat has a higher set point than the set point of the second thermostat.
A bottle heater comprising:
- a flexible band member having an inner heating surface adapted to be in contact with the bottle;
- a releasable retaining member for securing the flexible band member about the outer surface of the bottle;
- an electrical heating element disposed in the flexible band member for heating the flexible band member and extending over a heating element area;
- at least a first thermostat disposed within the heating element area over the flexible band member for sensing and controlling the temperature of the electric heating element;
- and
- wherein said flexible band member comprises a pair of layers of a rubber material having the electrical heating element disposed therebetween.
