The band is provided with at least one heater, a temperature sensor, a controller configured to activate the heater when the temperature measured by the sensor drops below a predetermined temperature range and deactivate the heater when the temperature measured by the sensor rises above the predetermined temperature range. The band further includes an electrical connector for connection to a supplemental heat-generating band. ## Claims ### Claim 1 A bottle temperature control apparatus comprising: (a) a heat-generating band configured to wrap around an exterior wall of a bottle and provided with a heater; (b) a temperature sensor mounted on the heat-generating band in contact with the exterior wall of the bottle for measuring the temperature of the liquid therein when the heat-generating band is wrapped around the exterior wall of the bottle; (c) a controller mounted on the heat-generating band and connected to the heater and the temperature sensor, and configured to activate the heater when the temperature measured by the temperature sensor drops below a predetermined temperature range and deactivate the heater when the temperature measured by the temperature sensor rises above the predetermined temperature range; and (d) an electrical connector coupled to the controller and adapted to be connected to a supplemental heater; (e) wherein the heat-generating band can be moved up or down or around the exterior wall of the bottle thereby moving the heater and the temperature sensor to a position where the liquid is located whether the bottle is oriented upright, sideway, or in an inverted and tilted feeding position. ### Claim 2 (depends on 1) The apparatus as claimed in claim 1, wherein the heat-generating band has two opposite ends provided with two cooperating fastening members respectively. ### Claim 3 (depends on 1) The apparatus as claimed in claim 1, wherein the heat-generating band has a length sufficient to wrap around the exterior wall of bottles of various sizes. ### Claim 4 (depends on 1) The apparatus as claimed in claim 1, wherein the heat-generating band is provided with a transparent window through which the liquid and liquid level inside the bottle can be revealed. ### Claim 5 (depends on 1) The apparatus as claimed in claim 1, wherein the controller comprises a switch to switch a power supply of the controller on or off. ### Claim 6 (depends on 1) The apparatus as claimed in claim 1, wherein the controller comprises a display for displaying the temperature being measured by the temperature sensor. ### Claim 7 (depends on 6) The apparatus as claimed in claim 6, wherein the display displays a warning message “TOO COLD” when the temperature measured by the temperature sensor drops below the predetermined temperature range, and display a warning message “TOO HOT” when the temperature measured by the temperature sensor rises above the predetermined temperature range. ### Claim 8 (depends on 1) The apparatus as claimed in claim 1, wherein the heat-generating band comprises a guiding rail extending transversely thereon, whereby the temperature sensor is slidably coupled to the guiding rail and movable between a first position where the temperature sensor is located at one side of the heat-generating band and a second position where the temperature sensor is located at the other side of the heat-generating band. ### Claim 9 (depends on 1) The apparatus as claimed in claim 1, wherein the heater is sandwiched between an inner conductive layer in contact with the exterior wall of the bottle and an outer insulating layer. ### Claim 10 (depends on 1) The apparatus as claimed in claim 1, wherein the controller comprises a circuit board with a central processing unit configured to automatically activate the heater when the temperature measured by the temperature sensor drops below a predetermined temperature range, and automatically deactivate the heater when the temperature measured by the temperature sensor rises above the predetermined temperature range. ### Claim 11 (depends on 1) The apparatus as claimed in claim 1, wherein the controller comprises a switch, a display, a central processing unit and a battery. ### Claim 12 (depends on 1) The apparatus as claimed in claim 1, wherein the controller is accommodated in a controller housing which is hingedly connected to the heat-generating band at an outer side thereof by a hinge. ### Claim 13 (depends on 1) The apparatus as claimed in claim 1, wherein the controller comprises a central processing unit configured to receive data transmitted from the sensor, display the data on a display, process the data, activate the heater when the temperature measured by the temperature sensor drops below a predetermined temperature range, and deactivating the heater when the temperature measured by the temperature sensor rises above the predetermined temperature range. ### Claim 14 (depends on 1) The apparatus as claimed in claim 1, wherein the controller comprises a battery for supplying electric energy to the sensor, the heater and the controller. ### Claim 15 (depends on 1) The apparatus as claimed in claim 1, further comprising a supplemental heat-generating band configured to wrap around the exterior wall of the bottle and carrying the supplemental heater. ### Claim 16 (depends on 15) The apparatus as claimed in claim 15, wherein the supplemental heat-generating band is provided with a transparent window through which the liquid and liquid level inside the bottle can be revealed. ### Claim 17 (depends on 1) The apparatus as claimed in claim 1, comprising a plurality of heaters disposed around the exterior wall of the bottle. ### Claim 18 (depends on 8) The apparatus as claimed in claim 8, wherein the temperature sensor is fixedly coupled to a slide button so as to facilitate the sliding of the temperature sensor along the guiding rail. ### Claim 19 (depends on 1) The apparatus as claimed in claim 1, wherein the electrical connector is connected to the supplemental heater by an electrical wire. ### Claim 20 (depends on 1) The apparatus as claimed in claim 1, wherein the bottle is a baby bottle.
