Electronic smoking article

1. An electronic vaping device configured to produce a vapor comprising:

a formulation;

a heater configured to at least partially vaporize the formulation;

a filter arranged downstream of the heater, the filter including,

a plug of filter material, the plug having an end surface and a side surface, and

at least one crushable flavor bead, the at least one crushable flavor bead comprising a rupturable shell and a flavor contained inside the rupturable shell; and

a compressible sheath adjacent the filter, the compressible sheath formed of at least one polymer, and the compressible sheath having an end surface defining an outlet and a side surface, the compressible sheath extending over at least a portion of each of the end surface and the side surface of the plug.

2. The electronic vaping device of claim 1 , wherein the plug comprises:

a first filter plug; and

a second filter plug, and

wherein the at least one crushable flavor bead is between the first filter plug and the second filter plug.

3. The electronic vaping device of claim 1 , wherein the filter has a length ranging from about 2 mm to about 10 mm and an outer diameter that is about the same or less than an inner diameter of an outer housing of the electronic vaping device.

4. The electronic vaping device of claim 1 , wherein the filter is detachable and a separate sleeve is configured to attach the filter to the electronic vaping device.

5. The electronic vaping device of claim 1 , wherein the filter is disposable.

6. The electronic vaping device of claim 1 , wherein the at least one crushable flavor bead comprises at least two flavor beads.

7. The electronic vaping device of claim 1 , wherein the at least one crushable flavor bead has a crush strength ranging from about 0.5 kilogram force to about 3 kilogram force.

8. The electronic vaping device of claim 1 , wherein the at least one flavor crushable bead has a diameter ranging from about 0.5 mm to about 5.0 mm.

9. The electronic vaping device of claim 1 , wherein the heater comprises a capillary tube in fluid communication with a reservoir, the reservoir containing the formulation.

10. The electronic vaping device of claim 9 , wherein the reservoir is pressurized and includes a mechanically or electrically operated valve at an outlet of the reservoir.

11. The electronic vaping device of claim 9 , wherein the reservoir is compressible, such that the formulation is manually pumped to the capillary tube.

12. The electronic vaping device of claim 1 , wherein the heater is a coil heater in communication with a filamentary wick which draws the formulation via capillary action.

13. The electronic vaping device of claim 12 , further comprising:

an outer tube extending in a longitudinal direction;

an inner tube within the outer tube; and

the formulation contained in an outer annulus between the outer tube and the inner tube,

wherein the coil heater is located in the inner tube and the filamentary wick is in communication with the formulation and surrounded by the coil heater, such that the filamentary wick delivers the formulation to the coil heater and the coil heater heats the formulation to a temperature sufficient to vaporize the formulation and form a vapor in the inner tube.

14. The electronic vaping device of claim 13 , further comprising:

a first section; and

a second section, the first section attachable to the second section,

wherein the filamentary wick, the formulation, and filter are contained in the first section, and a power supply configured to apply voltage across the heater is contained in the second section.

15. The electronic vaping device of claim 1 , wherein the filter material is selected from the group consisting of cellulose acetate, polyester, polypropylene, paper, and combinations thereof.

16. The electronic vaping device of claim 1 , wherein the flavor is menthol.

17. A kit comprising:

an electronic vaping device; and

a plurality of attachable filter elements each comprising a sheath, a plug of filter material, and a flavor bead, the plug including an end surface and a side surface, the sheath having an end surface defining an outlet and a side surface, the sheath extending over at least a portion of each of the end surface and the side surface of the plug, the sheath configured to slidingly fit with an end portion of the electronic vaping device, the sheath being sufficiently flexible such that an adult vaper smoker may ruptures the flavor bead by squeezing the sheath, whereby a content of the flavor bead is released.
