Abstract

An ejection system is provided which has a mechanism such as a plunger which is positioned to eject at least a portion of a cigarette from the lighter cavity upon actuation by a smoker. The plunger is also positionable to occlude the lighter opening to protect the lighter cavity from dust, moisture, etc. The plunger is shaped, located and arranged to apply a force on the cigarette end inserted into the lighter. Further, an icon based indicator informs the smoker of the status of a cigarette inserted into the lighter.

Claims

1. An ejector for ejecting a cigarette having a mouth end and a distal end from an electrical smoking system, said ejector comprising, in combination:

a housing for containing a cigarette, said housing having a cylindrical receptacle for receiving a cigarette inserted distal end first via an opening to be heated by the at least one heater such that an opposite cigarette mouth end protrudes from the lighter, and at least one heater contained in said housing, said heater being located in thermal proximity to an inserted cigarette, said heater being actuated responsive to draw on the protruding cigarette mouth end by a consumer to evolve tobacco flavor from said cigarette while inserted in said housing,

a movable contact surface, said contact surface having a size such that it may travel longitudinally through the cylindrical receptacle of the lighter and contact at least a central area of the inserted distal end of a cigarette, and

an actuator for moving said contact surface between a first position in the cylindrical receptacle to allow insertion of a cigarette and a second position in the cylindrical receptacle to move an inserted cigarette out of the cylindrical receptacle.

2. The ejection system according to claim 1, wherein said contact surface at the first position defines an air flow gap between said contact surface and an inserted end of a cigarette.

3. The ejection system according to claim 1, further comprising a plunger, said plunger defining said contact surface.

4. The ejection system according to claim 1, further comprising means for establishing a substantially air tight seal between the cylindrical receptacle and said plunger at the first position.

5. The ejection system according to claim 1, further comprising means for positioning said contact surface stationarily at the first and second positions.

6. The ejection system according to claim 1, further comprising means for biasing said contact surface from the second position toward the first position.

7. The ejection system according to claim 1, further comprising means for stationarily positioning said contact surface near the opening of the cylindrical receptacle, wherein said contact surface is further sized to occlude the opening of the cylindrical receptacle plunger.

8. The ejection system according to claim 1, further comprising means for occluding the opening of the cylindrical receptacle plunger.

9. The ejection system according to claim 1, further comprising means for establishing a substantially air tight seal between the cylindrical receptacle and ambient when said contact surface is positioned at the opening of the cylindrical receptacle.

10. The ejection system according to claim 1, wherein said contact surface at the first position defines an air flow gap between said contact surface and an inserted end of a cigarette such that the first puff of an inserted cigarette has a resistance to draw of approximately 5 to approximately 12 inches.

11. The ejection system according to claim 1, wherein said means for actuating comprises a switch located on an outer surface of the housing, and an actuation mechanism operatively connected to said switch and to said contact surface.

12. The ejection system according to claim 11, further comprising means for positioning said contact surface stationarily at the first and second positions.

13. The ejection system according to claim 12, wherein said means for positioning comprises at least one detent located on said actuation mechanism and a spring-biased ball for engaging and disengaging said at least one detent.

14. The ejection system according to claim 11, wherein the housing has a longitudinal axis, wherein said switch is movable parallel to the longitudinal axis of the housing.

15. The ejection system according to claim 1, further comprising a channel for travel of said actuation mechanism upon actuation of said switch.

16. The ejection system according to claim 15, wherein said channel is defined at least partially by walls of a power source.

17. The ejection system according to claim 16, wherein said channel is U-shaped.

21. The ejection system according to claim 1, wherein said contact surface is sized to contact a central area extending across a diameter of the inserted end of a cigarette.

18. An ejection system for an electrical cigarette lighter comprising at least one heater, a housing surrounding the at least one heater, and a cylindrical receptacle in the housing for receiving a cigarette inserted end first via an opening to be heated by the at least one heater such that an opposite cigarette mouth end protrudes from the lighter, the ejection system comprising:

a contact surface sized to travel longitudinally through the cylindrical receptacle of the lighter and to contact at least a central area of an inserted end of a cigarette,

means for actuating said contact surface between a first position in the cylindrical receptacle to allow insertion of a cigarette and a second position in the cylindrical receptacle to move an inserted cigarette out of the cylindrical receptacle, and

means for visually informing a smoker that an inserted cigarette has been heated a desired number of times.

19. The ejection system according to claim 18, wherein said means for visually informing comprises means for displaying a cigarette icon and means for correlating the display of said cigarette icon with the number of times an inserted cigarette has been heated.

20. The ejection system according to claim 19, wherein said cigarette icon comprises a filter icon and a plurality of segmented cigarette rod icons.

22. An electrical cigarette lighter for a cigarette having a mouth end and a distal end, said lighter comprising:

a housing surrounding a cylindrical receptacle for receiving a cigarette inserted end first via an opening;

at least one heater contained in said housing and producing inhalable tobacco flavor from a heated cigarette, said heater actuated in response to a draw on the cigarette from a consumer on an opposite cigarette mouth end which protrudes from the lighter; and

an ejection system comprising;

a contact surface sized to travel longitudinally through the cylindrical receptacle of the lighter and to contact the inserted distal end of a cigarette, and

means for actuating said contact surface between a first position in the cylindrical receptacle to allow insertion of a cigarette and a second position in the cylindrical receptacle to move an inserted cigarette out of the cylindrical receptacle.

23. The electrical cigarette lighter according to claim 22, wherein said contact surface is sized to contact a central area of the inserted end of a cigarette.
