Abstract

An electronic vaping device includes a housing, a planar heater, a heater support, a tank, and a wick. The housing extends in a longitudinal direction and has a tip end and a mouth-end. The tip end is closed and the mouth-end has an opening therein. The heater support supports the planar heater. The tank contains a pre-vapor formulation and is configured to slide into and out of the opening of the mouth-end of the housing. The wick extends from the tank and is configured to be in contact with the planar heater when the tank is inserted in the housing.

First claim

I claim:

1. An electronic vaping device comprising:
a housing extending in a longitudinal direction, the housing having a tip end and a mouth-end, the tip end being closed and the mouth-end having an opening therein; and
a tank containing a formulation, the tank configured to slide into and out of the opening of the mouth-end of the housing, the tank including,
two or more ribs on an outer surface of the tank, the two or more ribs extending longitudinally along the outer surface of the tank, the two or more ribs configured to space the outer surface of the tank from an inner surface of the housing so as to define a flow passage between the outer surface of the tank and the inner surface of the housing.

2. The electronic vaping device of claim 1 , further comprising:
a mouth-end insert configured to be inserted in the mouth-end of the housing.

3. The electronic vaping device of claim 2 , wherein the mouth-end insert includes at least one outlet.

4. The electronic vaping device of claim 1 , wherein the housing is unitary.

5. The electronic vaping device of claim 1 , further comprising:
a wick extending from the tank.

6. The electronic vaping device of claim 5 , wherein the wick is monolithic.

7. The electronic vaping device of claim 1 , further comprising:
a planar heater in the housing.

8. The electronic vaping device of claim 7 , further comprising:
a heater support configured to support the planar heater.

9. The electronic vaping device of claim 7 , wherein the planar heater comprises:
a patterned layer of platinum on a ceramic layer, the patterned layer of platinum being configured to be in electrical communication with a power supply through leads electrically connected to the patterned layer of platinum.

10. The electronic vaping device of claim 9 , wherein the power supply is configured to supply power to the patterned layer of platinum so as to resistively heat the patterned layer of platinum such that the planar heater may reach a temperature sufficient to vaporize the formulation.

11. The electronic vaping device of claim 9 , wherein the patterned layer of platinum has a resistivity of 1 to 6 ohms.

12. The electronic vaping device of claim 9 , wherein the leads are formed from platinum coated nickel wire.

13. The electronic vaping device of claim 9 , wherein the planar heater is in a shape of a polyhedron having a square, triangular, diamond or rectangular shaped base with rounded or sharp corners.

14. The electronic vaping device of claim 9 , wherein
the planar heater has a square or rectangular base,
a length and a width of the planar heater are each 1.5 mm to 4 mm, and
a thickness of the planar heater is 0.2 mm to 0.8 mm.

15. The electronic vaping device of claim 9 , wherein a glass layer is on the ceramic layer such that the patterned layer of platinum is between the ceramic layer and the glass layer.

16. The electronic vaping device of claim 9 , wherein
the ceramic layer is a first ceramic layer, and
a second ceramic layer is on the first ceramic layer such that the patterned layer of platinum is between the first ceramic layer and the second ceramic layer.

17. The electronic vaping device of claim 9 , wherein the ceramic layer is formed from alumina, titania, zirconia, yttria, yttria-stabilized zirconia, or any combination thereof.

18. The electronic vaping device of claim 9 , wherein
the patterned layer of platinum is 0.5 micron to 2 microns thick, and
the patterned layer has a width ranging from 1 micron to 100 microns.

19. The electronic vaping device of claim 9 , wherein the patterned layer of platinum has a sinuous pattern.

20. The electronic vaping device of claim 9 , wherein the patterned layer of platinum has a U-shaped pattern.
