Abstract

An electrically warmed baby bottle and recharging system are provided. The baby bottle is a container made of an electrically non-conductive material with a heating wire embedded in its walls. Mounted below the container is a temperature regulation system including a thermostat, a rechargeable battery and an on-off switch enclosed within a water-tight housing. The electrically warmed baby bottle fits into a battery charger which is designed with plug prongs which enter the water-tight housing through self-sealing ports so as to recharge the battery.

Claims

1. An electrically warmed baby bottle capable of maintaining its contents at a predetermined temperature which comprises:

(a) a container made of an electrically non-conductive material;

(b) an electrically conductive heating wire embedded in the wall of the container; and

(c) a temperature regulation system mounted below the container in a water-tight housing having self-sealing ports, the temperature regulation system being composed of;

(i) a thermostat which extends through the housing into the interior of the container, the thermostat being able to regulate the flow of electricity to the conductive heating wire so as to maintain the interior of the container at a predetermined temperature;

(ii) a rechargeable battery connected to the conductive heating wire via the thermostat, the rechargeable battery being mounted in such a manner so as to allow plug prongs of a battery charger to transverse the water-tight housing through the self-sealing ports for recharging the battery; and

(iii) an on-off switch, the on-off switch being mounted within the water-tight housing and accessible from the exterior of the water-tight housing by indenting a flexible section of the housing.

2. An electrically warmed baby bottle of claim 1, wherein the container is made of plastic.

3. An electrically warmed baby bottle of claim 1, wherein the container is made of glass.

4. An electrically warmed baby bottle of claim 1, wherein electrically conductive heating wire comprises a series of parallel circumferential loops.

5. An electrically warmed baby bottle of claim 1, wherein the electrically warmed baby bottle is washable.

6. An electrically warmed baby bottle of claim 5, wherein the electrically warmed baby bottle is dishwasher safe.

7. An electrically warmed baby bottle of claim 1 further comprising a layer of non-heat conductive material exterior to the heating wire.

8. An electrically warmed baby bottle and recharging system which comprises:

(1) an electrically warmed baby bottle composed of;

(a) a container made of an electrically non-conductive material;

(b) an electrically conductive heating wire embedded in the wall of the container; and

(c) a temperature regulation system mounted below the container in a water-tight housing having self-sealing ports, the temperature regulation system being composed of;

(i) a thermostat which extends through the housing into the interior of the container, the thermostat being able to regulate the flow of electricity to the conductive heating wire so as to maintain the interior of the container at a predetermined temperature;

(ii) a rechargeable battery connected to the conductive heating wire via the thermostat, the rechargeable battery being mounted in such a manner so as to allow plug prongs of a battery charger to transverse the water-tight housing through the self-sealing ports for recharging the battery;

(iii) an on-off switch, the on-off switch being mounted within the water-tight housing and accessible from the exterior of the water-tight housing by indenting a flexible section of the housing; and

(2) a battery charger constructed in such a manner so as to conform to the shape of the water-tight housing of the baby bottle, the battery charger having plug prongs which align with the self-sealing ports of the baby bottle so that when the baby bottle is placed in the battery charger, the plug prongs of the battery charger enter the water-tight housing through the self-sealing ports and are in electrical contact with the rechargeable battery.

9. An electrically warmed baby bottle and recharging system of claim 8, wherein the battery charger further comprises a safety mechanism which severs the flow of current to the plug prongs when the baby bottle is removed.
