Abstract

In a system comprising an electronic smoking device and a capsule (6), the electronic smoking device includes a housing, an electric power source, an electrically heatable atomizer adapted to atomize a liquid supplied from the capsule (6), an interface adapted to mount the capsule (6) at the electronic smoking device, and control electronics. The capsule (6) comprises a shell (30) having a longitudinal axis and containing a liquid. A first end side (32) of the shell (30) is sealed by a puncturable membrane. The capsule (6) is adapted to be mounted at the electronic smoking device via the interface. The shell (30) has a triangular-like cross-sectional shape (50) transversely to its longitudinal axis, in an area which extends over at least part of the shell (30) in a direction along its longitudinal axis.

Claims

1. A system comprising:

an electronic smoking device, which comprises a housing, an electric power source, an electrically heatable atomizer adapted to atomize a liquid supplied from a capsule, an interface adapted to mount the capsule at the electronic smoking device, and control electronics, and

a capsule, which comprises a shell having a longitudinal axis and containing a liquid, a first end side of the shell being sealed by a puncturable membrane, wherein the capsule is adapted to be mounted at the electronic smoking device via the interface, characterised in that the shell has a triangular-like cross-sectional shape transversely to its longitudinal axis, in an area which extends over at least part of the shell in a direction along its longitudinal axis.

2. The system of claim 1, wherein a peripheral area of the shell adjacent to its first end side fits into a connection device provided at the interface, optionally in a form-fit manner, when the capsule is mounted at the electronic smoking device.

3. The system of claim 2, wherein the connection device comprises a pipe having an end face, wherein at least one protrusion at the shell rests at the end face of the pipe when the capsule is mounted at the electronic smoking device.

4. The system of claim 1, wherein a peripheral area of the shell adjacent to its first end side has a triangular-like cross-sectional shape.

5. The system of claim 1, wherein a peripheral area of the shell remote from its first end side has a triangular-like cross-sectional shape.

6. The system of claim 1, wherein the cross-sectional shape of the shell varies along its longitudinal axis.

7. The system of claim 1, wherein a triangular-like cross-sectional shape of the shell is defined, in an area which extends over at least part of the shell in a direction along its longitudinal axis, by a closed line having three sections connecting three rounded corner zones.

8. The system of claim 7, wherein the respective sections connecting the corner zones are shaped as convex bows.

9. The system of claim 1, wherein the shell comprises a step, along at least part of its circumference, formed by cross-sectional shapes of the shell which are different on both sides of the step.

10. The system of claim 1, wherein the capsule is surrounded by a sleeve, at least along part of the shell in a direction along its longitudinal axis when the capsule is mounted at the electronic smoking device.

11. The system of claim 10, wherein at least part of the sleeve is formed by the housing.

12. The system of claim 10, wherein at least part of the sleeve is formed by a separate replaceable article.

13. The system of claim 10, wherein the shell touches the sleeve in spots or in some areas, while space serving as an aerosol pathway is provided in other areas between the shell and the sleeve when the capsule is mounted at the electronic smoking device.

14. The system of claim 1, wherein the capsule is surrounded by an end cap, at least along part of the shell in a direction along its longitudinal axis, when the capsule is mounted at the electronic smoking device, and wherein the end cap is detachable from the housing and comprises a mouth piece.

15. The system of claim 14, wherein the end cap does not touch the capsule, or the end cap touches the capsule at an end side of the capsule only when the capsule is mounted at the electronic smoking device.

16. A capsule for use with an electronic smoking device, wherein the capsule comprises a shell having a longitudinal axis and containing a liquid, a first end side of the shell being sealed by a puncturable membrane, wherein the shell has a triangular-like cross-sectional shape transversely to its longitudinal axis in an area which extends over at least part of the shell in a direction along its longitudinal axis.

18. The capsule of claim 16, further comprising an interface adapted to mount the capsule at an electronic smoking device;

and

wherein a peripheral area of the shell adjacent to its first end side fits into a connection device provided at the interface, optionally in a form-fit manner when the capsule is mounted at the electronic smoking device; and

wherein the connection device comprises a pipe having an end face, wherein at least one protrusion at the shell rests at the end face of the pipe when the capsule is mounted at the electronic smoking device

19. The capsule of claim 16, wherein the cross-sectional shape of the shell varies along its longitudinal axis.

20. The capsule of claim 16, wherein a triangular-like cross-sectional shape of the shell is defined, in an area which extends over at least part of the shell in a direction along its longitudinal axis, by a closed line having three sections connecting three rounded corner zones, wherein the the respective sections connecting the corner zones are optionally shaped as convex bows.

21. The capsule of claim 16, wherein the shell comprises a step, along at least part of its circumference, formed by cross-sectional shapes of the shell which are different on both sides of the step.

17. (canceled)
