Fluid reservoir for an aerosol generation device, combination of fluid reservoir and primary fluid package, and aerosol generation device for use with the fluid reservoir

1. A fluid reservoir which is attachable to an aerosol generation device for guiding a fluid to the aerosol generation device, the fluid reservoir comprising:

a fluid container; and

an interface portion affixed to the fluid container and configured to attach the fluid container to the aerosol generation device, wherein

the interface portion includes a locking element configured to lock the fluid container to the aerosol generation device after attachment of the fluid container to the aerosol generation device, and

the interface portion includes a weakened portion that is breakable to enable detachment of the fluid container from the aerosol generation device.

2. The fluid reservoir according to claim 1 , further comprising an adapter, wherein the adapter comprises the interface portion.

3. The fluid reservoir according to claim 1 , wherein the fluid container is formed integrally with the interface portion.

4. The fluid reservoir according to claim 1 , further comprising a lid element for sealing the fluid container.

5. The fluid reservoir according to claim 4 , wherein the lid element is configured so that, after sealing the fluid container, the lid element cannot be detached from its sealing position without breaking the lid element or the fluid container.

6. The fluid reservoir according to claim 1 , wherein the locking element is configured so that it has to be manually broken before detachment of the fluid container from the aerosol generation device.

7. The fluid reservoir according to claim 1 , wherein the locking element is configured so that the locking element is broken when detaching the fluid container from the aerosol generation device.

8. The fluid reservoir according to claim 1 , wherein the interface portion of the fluid reservoir further has a valve element for sealing an end of the fluid container and regulating the fluid flow to the aerosol generation device.

9. The fluid reservoir according to claim 1 , wherein the interface portion of the fluid reservoir further has a wall element sealing an end of the fluid container, and

the wall element has at least one weakened portion facilitating at least partial breaking of the wall element.

10. A combination of the fluid reservoir according to claim 1 and a primary fluid package, wherein

the primary fluid package has at least one chamber containing a fluid therein.

11. The combination according to claim 10 , wherein the fluid reservoir and the primary fluid package are arranged together in a single package.

12. An aerosol generation device which is configured for use with the fluid reservoir according to claim 1 , the aerosol generation device having:

an attachment portion for receiving the interface portion of the fluid reservoir, wherein

the aerosol generation device comprises the fluid reservoir according to claim 1 .

13. The aerosol generation device according to claim 12 , further having an opening element for opening the interface portion of the fluid reservoir and guiding the fluid from the fluid container to the aerosol generation device.

14. The aerosol generation device according to claim 12 , wherein the attachment portion has at least one opening, and

the at least one opening is arranged so as to be closed by the interface portion of the fluid reservoir after attachment of the fluid container to the aerosol generation device.
