Abstract

An electronic vaping device includes a housing extending in a longitudinal direction, a reservoir in the housing, the reservoir configured to store a pre-vapor formulation, a heater in the housing, the heater configured to heat the pre-vapor formulation, at least one portion formed of a material including at least one polymer and at least one oxygen sequestering agent, and a power supply.

First claim

We claim:

1. An electronic vaping device comprising:
a housing extending in a longitudinal direction;
a reservoir in the housing, the reservoir configured to store a pre-vapor formulation;
a heater in the housing, the heater configured to heat the pre-vapor formulation;
at least one portion formed of a material including at least one polymer and at least one oxygen sequestering material, the at least one oxygen sequestering material configured to absorb atmospheric oxygen, the at least one portion including at least a portion of the housing, at least a portion of the reservoir, at least a portion of a mouth-end insert, at least a portion of a connector, at least a portion of an end cap, or any combination thereof; and
a power supply configured to selectively supply power to the heater.

2. The electronic vaping device of claim 1 , wherein the at least one polymer is a natural polymer or a synthetic polymer, and wherein the at least one polymer includes low density polyethylene, high density polyethylene, low density polypropylene, high density polypropylene, poly(dimethylsiloxane), or any combination thereof.

3. The electronic vaping device of claim 1 , wherein the oxygen sequestering material is an ultraviolet (UV) activated oxygen sequestering material.

4. The electronic vaping device of claim 1 , wherein the oxygen sequestering material includes 1,2 polybutadiene, an anthroquinone system, and a three phase blend including a reactive double bond, a photoinitiator, a transition metal catalyst, or any combination thereof.

5. The electronic vaping device of claim 1 , wherein the oxygen sequestering material includes poly(ethylene/ methyl acrylate/cyclohexene-methyl acrylate) (EMCM).

6. The electronic vaping device of claim 1 , wherein the material includes about 5% to about 99% of the polymer and about 1% to about 95% of the oxygen sequestering material.

7. The electronic vaping device of claim 1 , wherein the at least one portion is configured to absorb about 0.5 mL to about 5.0 mL of pure oxygen.

8. The electronic vaping device of claim 1 , wherein the electronic vaping device has a shelf-life of at least 1 year.

9. A cartridge of an electronic vaping device comprising:
a housing extending in a longitudinal direction;
a reservoir in the housing, the reservoir configured to store a pre-vapor formulation;
a heater in the housing, the heater configured to heat the pre-vapor formulation; and
at least one portion of the cartridge formed of a material including at least one polymer and at least one oxygen sequestering material, the at least one oxygen sequestering material configured to absorb atmospheric oxygen, the at least one portion including at least a portion of the housing, at least a portion of the reservoir, at least a portion of a mouth-end insert, at least a portion of a connector, at least a portion of an end cap, or any combination thereof.

10. The cartridge of claim 9 , wherein the at least one polymer includes low density polyethylene, high density polyethylene, low density polypropylene, high density polypropylene, poly(dimethylsiloxane), or am combination thereof.

11. The cartridge of claim 9 , wherein the oxygen sequestering material is an ultraviolet (UV) activated oxygen sequestering material.

12. The cartridge of claim 9 , wherein the oxygen sequestering material includes 1,2 polybutadiene, an anthroquinone system, and a three phase blend including a reactive double bond, a photoinitiator, a transition metal catalyst, or any combination thereof.

13. The cartridge of claim 9 , wherein the oxygen sequestering material includes poly(ethylene/methyl acrylate/cyclohexene-methyl acrylate) (EMCM).

14. The cartridge of claim 9 , wherein the material includes about 5% to about 99% of the polymer and about 1% to about 95% of the oxygen sequestering material.

15. The cartridge of claim 9 , wherein the at least one portion is configured to absorb about 0.5 mL to about 5.0 mL of pure oxygen.

16. The cartridge of claim 9 , wherein the cartridge has a-shelf-life of at least about 1 year.

17. A portion of an electronic vaping device, the portion formed of a material including at least one polymer and at least one oxygen sequestering material, the at least one oxygen sequestering material configured to absorb atmospheric oxygen, the portion including at least a portion of the housing, at least a portion of a reservoir, at least a portion of a mouth-end insert, at least a portion of a connector, at least a portion of an end cap of an electronic vaping device, or any combination thereof.

18. The portion of claim 17 , wherein the at least one oxygen sequestering material is coated on a surface that can interact with an atmosphere surrounding the portion.

19. A method of prolonging a shelf-life of an electronic vaping device, the method comprising:
incorporating at least one portion formed of a material including at least one polymer and at least one oxygen sequestering material, the at least one oxygen sequestering material configured to absorb atmospheric oxygen, the at least one portion including at least a portion of housing, at least a portion of a reservoir, at least a portion of a mouth-end insert, at least a portion of a connector, at least a portion of an end cap of an electronic vaping device, or any combination thereof.
