## Abstract

There is provided a sachet of aerosol-forming substrate for an electrically heated aerosol-generating device, the sachet including an aerosol-forming substrate disposed within the sachet, and an electrical heater element including first and second electrically conductive portions, the electrical heater element being disposed within the sachet and in direct contact with the aerosol-forming substrate, and the first and the second electrically conductive portions are configured to connect the electrical heater element with an external power supply. An electrically operated aerosol-generating device for a sachet is also provided. And, a method of manufacturing a sachet is provided.

## Claims

### Claim 1

An electrically operated aerosol-generating device, comprising:
a power supply;
electronic control circuitry;
a cavity configured to receive a sachet of aerosol-forming substrate, the sachet comprising:
an aerosol-forming substrate disposed within the sachet, and
an electrical heater element comprising first and second electrically conductive portions,
wherein the electrical heater element is disposed within the sachet and is in direct contact with the aerosol-forming substrate;
a sachet retainer configured to retain the sachet in the cavity;
at least one piercing element configured to pierce the sachet of aerosol-forming substrate when the sachet is received in the cavity; and
electrical contacts disposed adjacent the cavity and being configured to allow the first and the second electrically conductive portions of the electrical heater element to be electrically connected to the power supply,
wherein the sachet retainer is further configured to maintain electrical contact between the electrical heater element and the electrical contacts.

### Claim 2

An electrically operated aerosol-generating device, comprising,
a power supply;
electronic control circuitry;
a cavity configured to receive a sachet of aerosol-forming substrate, the sachet comprising:
an aerosol-forming substrate disposed within the sachet, and
an electrical heater element comprising first and second electrically conductive portions,
wherein the electrical heater element is disposed within the sachet and is in direct contact with the aerosol-forming substrate,
a sachet retainer configured to retain the sachet in the cavity,
a first set of at least one piercing element and a second set of at least one piercing element, wherein the first set is configured to pierce a first side of the sachet and the second set is configured to pierce a second side of the sachet to form an airflow pathway through the sachet; and
electrical contacts disposed adjacent the cavity and being configured to allow the first and the second electrically conductive portions of the electrical heater element to be electrically connected to the power supply,
wherein the sachet retainer is further configured to maintain electrical contact between the electrical heater element and the electrical contacts.

### Claim 3 (depends on 1)

The electrically operated aerosol-generating device according to claim 1, wherein the at least one piercing element is hollow, such that an airflow pathway is formed through the at least one piercing element and the sachet.

### Claim 4 (depends on 2)

The electrically operated aerosol-generating device according to claim 2, wherein each of the first set of at least one piercing element and the second set of at least one piercing element is hollow, such that the airflow pathway is formed through the first set of at least one piercing element and the second set of at least one piercing element and the sachet.

### Claim 5 (depends on 1)

The electrically operated aerosol-generating device according to claim 1, wherein the sachet retainer comprises a lid movable between a first position in which the sachet is insertable into the cavity, and a second position in which the sachet is retained in the cavity.

### Claim 6 (depends on 2)

The electrically operated aerosol-generating device according to claim 2, wherein the sachet retainer comprises a lid movable between a first position in which the sachet is insertable into the cavity, and a second position in which the sachet is retained in the cavity.
