Abstract

A container for an aerosol-generating substrate 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 the 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 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 electrical contacts of the container; and 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.

Claims

1. A container for an aerosol-generating substrate, comprising:

a piercing area configured to be pierced by a piercing element of an 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 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 provided 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 a further cap, the further cap being sealed on an opposite end of the casing from the cap, configured to form a sealed container.

11. The container according to claim 10, the further cap comprising a further heater having electrical contacts, the further heater defining a boundary of a further piercing area.

12. The container according to claim 1, wherein the aerosol-forming substrate comprises nicotine, and wherein the aerosol-forming substrate is configured to be accessible once when the piercing area has been pierced.

13. An electrically heated aerosol-generating device, comprising:

a power supply;

a cavity configured to receive a container according to claim 1 containing the 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.

14. The electrically heated aerosol-generating device according to claim 13, further comprising:

at least one air inlet at a distal end of the electrically heated aerosol-generating device; and

at least one air outlet at a proximal end of the electrically heated aerosol-generating device,

wherein the piercing means is an elongate piercing member, and the at least one air inlet and the at least one air outlet are arranged to define an airflow pathway extending from the at least one air inlet to the at least one air outlet, and through the container about the elongate piercing member.

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

16. A method of manufacturing a container comprising an aerosol-generating substrate, 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 the aerosol-generating substrate; and

sealing each container of the plurality of containers with a cap of the plurality of caps comprising the heater elements.

17. The method according to claim 16, further comprising forming the electrically resistive track by stamping and/or printing.
