Abstract

A portable endothermic caulk warmer for warming at least one tube of endothermic caulk. This caulk warmer having an insulated housing, at least one AC heating pad, a AC/DC power inverter and a DC rechargeable battery.

Claims

1. A portable caulk warmer for warming at least one tube of caulk, said caulk warmer comprising:

a housing for holding said caulk, said housing having an opening therein, said opening able to be opened and closed, said housing having at least one side wall and a bottom wall, said side wall and said bottom wall defining a housing interior;

at least one heating pad for supplying a source of heat to said housing interior, said heating pad electrically connected to a battery, said heating pad located inside said housing interior, said heating pad is configured to be powered by alternating current power;

a power source for supplying an electrical current to said heating pad, wherein said power source is a rechargeable battery configured to supply direct current power; and

a power inverter for inverting said battery'"'"'s direct current power to alternating current thereby providing the alternating current required by said heating pad.

2. The caulk warmer of claim 1, wherein said housing is insulated.

3. The caulk warmer of claim 1, wherein the number of heating pads is two.

4. A portable caulk warmer for warming at least one tube of caulk, said caulk warmer comprising:

an insulated housing for holding said caulk, said insulated housing having an opening therein, said opening able to be opened and closed, said housing having a plurality of side walls and a bottom wall, said side walls and said bottom wall defining a housing interior;

at least one alternating current heating pad for supplying a source of heat to said housing interior, said heating pad electrically connected to a rechargeable battery via a power inverter, said heating pad located inside said housing interior;

a direct current rechargeable battery for supplying an electrical current to said heating pad, said battery configured for connection with an alternating current power source thereby allowing said rechargeable battery to be recharged; and

a direct current to alternating current power inverter connecting between said battery and said heating pad for allowing said battery to power said heating pad;

wherein said battery can be charged through connection with said power source, whereby after said battery is charged said battery can be disconnected from said power source;

wherein said battery via said inverter powers said heating pad thereby warming said housing interior.

5. The caulk warmer of claim 4, wherein said insulated housing comprising a plurality of handles for allowing said housing to be lifted.

6. The caulk warmer of claim 4, wherein the number of AC heating pads is two.

7. The caulk warmer of claim 4, wherein said opening is closed through use of a lid.

8. The caulk warmer of claim 6, wherein said lid is insulated.

9. A portable caulk warmer for warming a plurality of tubes of caulk, said caulk warmer comprising:

an insulated housing for holding said caulk, said insulated housing having an opening therein, said opening closed by an insulated lid, said housing having a plurality of side walls and a bottom wall, said side walls and said bottom wall defining a housing interior;

a first alternating current heating pad for supplying a source of heat to said housing interior, said first alternating current heating pad electrically connected to a rechargeable battery via a power inverter, said first alternating current heating pad located inside said housing interior;

a second alternating current heating pad for supplying a source of heat to said housing interior, said second alternating current heating pad electrically connected to a rechargeable battery via a power inverter, said second alternating current heating pad located inside said housing interior;

a direct current rechargeable battery for supplying an electrical current to said first and second heating pads, said battery configured for connection with an alternating current power source thereby allowing said rechargeable battery to be recharged; and

a direct current to alternating current power inverter connecting between said battery and said first and second heating pads for allowing said battery to power said first and second heating pads;

wherein said battery can be charged through connection with said power source, whereby after said battery is charged said battery can be disconnected from said power source;

wherein said battery via said inverter powers said first and second heating pads thereby warming said housing interior.

10. The caulk warmer of claim 9, wherein said insulated housing comprising a plurality of handles for allowing said housing to be lifted.
