System with electronic smoking device and capsule
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.
1. An electronic smoking device, comprising:
a housing adapted to receive a capsule;
the capsule including a shell containing a liquid;
a first end of the shell sealed by a puncturable membrane;
a portion of the shell having a triangular cross-sectional shape projects out of the housing when the capsule is inserted into the electronic smoking device, thus providing space serving as an aerosol pathway in areas between the shell and the housing; and
the capsule having three radially spaced apart protrusions at a center section of the capsule contacting an inner cylindrical surface of the housing, the protrusions forming a stop which limits how far the capsule can be inserted into the housing.
2. The electronic smoking device of claim 1 with the shell having three corner zones and three convex bow areas, with one convex bow area between adjacent corner zones, at the first end of the shell; and the shell having a cylindrical second end opposite from the first end.
3. The electronic smoking device of claim 2 with the convex bow areas adapted to provide open spaces between the capsule and an inner wall of the housing when the capsule is inserted into the housing.
4. The electronic smoking device of claim 2 with the first end of the shell having a flat end surface.
5. The electronic smoking device of claim 1 further comprising an electric power source and an electrically heatable atomizer electrically connected to control electronics in the housing.
6. The electronic smoking device of claim 5 wherein the portion of the shell having the triangular cross-sectional shape has three corner zones contacting a circular surface in the housing, and with open spaces between adjacent corner zones providing aerosol pathways.
7. The electronic smoking device 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.
