Abstract

An aerosol-generating system is provided, including a first container including at least one aerosol-generating substrate; a rupturing system including a first tube and a second tube, the first and second tubes being arranged in operational engagement defining a volume, wherein the first and second tubes are movable relative to each other along a first motion path from a first position to a second position, such that the defined volume is larger in the first position than in the second position, wherein the first tube includes a first rupturing member disposed at least partially inside the first tube, such that in the first position, the first rupturing member is contained completely in the defined volume of the first and second tubes, and wherein in the second position, the first rupturing member at least partially protrudes from the defined volume to rupture the container including said substrate.

First claim

The invention claimed is:

1. A rupturing system, comprising:
a first hollow tube and a second hollow tube, the first hollow tube and the second hollow tube each comprising an external surface and an internal surface, the first hollow tube extending longitudinally between a first tube proximal end transverse cross section and a first tube distal end transverse cross section, the second hollow tube extending longitudinally between a second tube proximal end transverse cross section and a second tube distal end transverse cross section, the first hollow tube and the second hollow tube being arranged in operational engagement such that, in the operationally engaged first hollow tube and second hollow tube, the first tube distal end transverse cross section is longitudinally positioned between the second tube proximal end transverse cross section and the second tube distal end transverse cross section, and the second tube proximal end transverse cross section is longitudinally positioned between the first tube proximal end transverse cross section and the first tube distal end transverse cross section, and such that the operationally engaged first hollow tube and second hollow tube extend longitudinally between the first tube proximal end transverse cross-section and the second tube distal end transverse cross-section, the operationally engaged first hollow tube and second hollow tube defining a volume longitudinally delimited by the first tube proximal end transverse cross-section and the second tube distal end transverse cross-section and transversely delimited by the internal surface of the first hollow tube and the internal surface of the second hollow tube,
wherein the first hollow tube and the second hollow tube are movable relative to each other along a first motion path from a first position to a second position, such that the defined volume is larger in the first position than in the second position,
wherein the first hollow tube comprises a first rupturing member, disposed at least partially inside the first hollow tube, such that in the first position, the first rupturing member is contained completely in the defined volume, and
wherein in the second position, the first rupturing member at least partially protrudes from the defined volume to rupture a container.

2. The rupturing system according to claim 1 , a guide member of the second hollow tube being a second rupturing member, wherein in the second position, the second rupturing member at least partially protrudes from the defined volume into a second container.

3. An aerosol-generating system, comprising:
a first container comprising at least one aerosol-generating substrate; and
a rupturing system, comprising a first hallow tube and a second hollow tube, the first hollow tube and the second hollow tube each comprising an external surface and an internal surface, the first hollow tube extending longitudinally between a first tube proximal end transverse cross section and a first tube distal end transverse cross section, the second hollow tube extending longitudinally between a second tube proximal end transverse cross section and a second tube distal end transverse cross section, the first hollow tube and the second hollow tube being arranged in operational engagement such that, in the operationally engaged first hollow tube and second hollow tube, the first tube distal end transverse cross section is longitudinally positioned between the second tube proximal end transverse cross section and the second tube distal end transverse cross section, and the second tube proximal end transverse cross section is longitudinally positioned between the first tube proximal end transverse cross section and the first tube distal end transverse cross section, and such that the operationally engaged first hollow tube and second hollow tube extend longitudinally between the first tube proximal end transverse cross-section and the second tube distal end transverse cross-section, the operationally engaged first hollow tube and second hollow tube defining a volume longitudinally delimited by the first tube proximal end transverse cross-section and the second tube distal end transverse cross-section and transversely delimited by the internal surface of the first hollow tube and the internal surface of the second hollow tube,
wherein the first hollow tube and the second hollow tube are movable relative to each other along a first motion path from a first position to a second position, such that the defined volume is larger in the first position than in the second position,
wherein the first hollow tube comprises a first rupturing member, disposed at least partially inside the first hollow tube, such that in the first position, the first rupturing member is contained completely in the defined volume, and
wherein in the second position, the first rupturing member at least partially protrudes from the defined volume to rupture the first container comprising the at least one aerosol-generating substrate.

4. The aerosol-generating system according to claim 3 ,
wherein the first rupturing member comprises a distal end comprising a rupturing portion and a proximal end, and
wherein the first rupturing member is coupled to the first tube at the proximal end such that during movement of the first tube along the first motion path, the rupturing portion describes a second motion path that is at least partially not parallel to the first motion path.

5. The aerosol-generating system according to claim 4 , wherein the second hollow tube comprises a guide member configured to guide the rupturing portion of the first rupturing member along the second motion path.

6. The aerosol-generating system according to claim 5 ,
wherein the guide member comprises a cam surface, and
wherein the first rupturing member further comprises a cam follower surface, such that during relative movement of the first hollow tube and the second hollow tube from the first position to the second position along the first motion path, the cam follower surface of the first rupturing member engages with the cam surface of the guide member to guide the rupturing portion of the first rupturing member along the second motion path.

7. The aerosol-generating system according to claim 3 , a guide member of the second hollow tube being a second rupturing member, wherein in the second position, the second rupturing member at least partially protrudes from the defined volume into a second container.

8. The aerosol-generating system according to claim 7 ,
wherein the second rupturing member comprises a distal end comprising a rupturing portion and a proximal end, and
wherein the second rupturing member is connected to the second tube at the proximal end such that during movement of the second tube along the first motion path, the rupturing portion describes a third motion path that is at least partially not parallel to the first motion path.

9. The aerosol-generating system according to claim 3 , wherein the first rupturing member is coupled to the first tube by a resilient member.

10. The aerosol-generating system according to claim 3 , wherein an external surface of the first hollow tube is configured to slide adjacent an internal surface of the second hollow tube.

11. The aerosol-generating system according to claim 10 , wherein the external surface of the first hollow tube and the internal surface of the second hollow tube each comprise resilient protrusions configured to cooperate to retain the system in the first position until a longitudinal compressive force is applied to the system.
