Abstract

A container for use in an electrically heated aerosol-generating device is provided, the container including a piercing area, wherein the electrically heated aerosol-generating device has a piercing element configured to pierce the piercing area; a casing; and a cap including the piercing area and a heater, the heater defining a boundary of the piercing area. An electrically heated aerosol-generating device is also provided, including a power supply; a cavity configured to receive a container; electrical contacts connected to the power supply and configured to couple the power supply to the heater of the container through electrical contacts of the container; means for piercing the piercing area of the container when the container is received in the cavity. A method of manufacturing a container including an aerosol-generating substrate is also provided.

First claim

The invention claimed is:

1. A container for an electrically heated aerosol-generating device, comprising:
a piercing area configured to be pierced by a piercing element of the electrically heated aerosol-generating device:
a casing; and
a cap including the piercing area and a heater, the heater defining a boundary of the piercing area.

2. The container according to claim 1 , the heater having an interior edge and an exterior edge, wherein the interior edge of the heater defines the boundary of the piercing area.

3. The container according to claim 1 , the heater having an interior edge and an exterior edge, wherein the exterior edge of the heater defines the boundary of the piercing area.

4. The container according to claim 1 , wherein the heater is arranged within an annular portion of the cap.

5. The container according to claim 4 , wherein the heater has a wave shape and is disposed within the annular portion of the cap, such that a total length of the heater is greater than a circumferential length of the annular portion.

6. The container according to claim 1 , wherein the heater comprises two electrical contacts, the first electrical contact disposed at a first distance from an edge of the cap, and the second electrical contact disposed at a second distance from the edge of the cap.

7. The container according to claim 1 , wherein the casing has a substantially circular cross-sectional shape.

8. The container according to claim 1 , wherein the heater comprises at least one electrically resistive track disposed on a flexible substrate.

9. The container according to claim 8 , wherein the cap is a laminate comprising the flexible substrate.

10. The container according to claim 1 , further comprising an aerosol-forming substrate comprising nicotine, wherein the aerosol-forming substrate is configured to be accessible when the piercing area has been pierced.

11. An electrically heated aerosol-generating device, comprising:
a power supply;
a cavity configured to receive a container according to claim 1 containing an aerosol-forming substrate;
electrical contacts connected to the power supply and configured to couple the power supply to the heater of the container through the electrical contacts of the container; and
means for piercing the piercing area of the container when the container is received in the cavity.

12. The electrically heated aerosol-generating device according to claim 11 , the piercing means being a piercing element, the device further comprising:
a mouthpiece comprising the piercing element, at least one air inlet, and at least one air outlet,
wherein the piercing means comprises at least one first conduit extending between the at least one air inlet and a distal end of the piercing element, and at least one second conduit extending between a distal end of the piercing element and the at least one air outlet, configured such that when a user draws on the mouthpiece, air flows along an airflow pathway extending from the at least one air inlet, through the at least one first conduit, through a portion of the container, through the at least one second conduit, and exits the at least one outlet.

13. The electrically heated aerosol-generating device according to claim 12 , wherein the piercing means is an electrical insulator.

14. A method of manufacturing a container, comprising:
providing a web of flexible substrate material;
applying a plurality of electrically resistive tracks to the web of flexible substrate material;
cutting the web of flexible substrate to form heater elements each comprising an electrically resistive track;
providing a web of pierceable material;
applying the heater elements to the web of pierceable material;
cutting the web of pierceable material to form a plurality of caps;
providing a plurality of containers;
filling each container of the plurality of containers with an aerosol-generating substrate; and
sealing each container of the plurality of containers with a cap of the plurality of caps comprising the heater elements.

15. The method according to claim 14 , further comprising forming the electrically resistive track by stamping and/or printing.
