Cartridge, components and methods for generating an inhalable medium
View Patent ↗A cartridge is provided for use with an apparatus for generating an inhalable medium. The cartridge has a container for holding a liquid and a receptacle for receiving a solid material. A shell is provided around the outside of the liquid container. A channel is defined between the liquid container and the shell. Liquid exiting the container can flow, in the form of at least one of a vapor and an aerosol, through the channel to the receptacle and through solid material received by the receptacle in use.
1. A cartridge for use with an apparatus for generating an inhalable medium, the cartridge comprising:
a liquid container for holding a liquid;
a receptacle for receiving a solid material; and
a shell around the outside of the liquid container,
wherein the shell and the liquid container define between them a channel, wherein the channel is in the form of a substantially tubular channel which does not completely surround the liquid container, and wherein the cartridge is arranged such that in use liquid exiting the liquid container can flow, in the form of at least one of a vapor or an aerosol, through the channel to the receptacle and through solid material received by the receptacle in use.
2. The cartridge according to claim 1 , wherein the cartridge has plural channels defined between the liquid container and the shell.
3. The cartridge according to claim 1 , wherein the liquid container is frustoconical.
4. The cartridge according to claim 1 , comprising a heater associated with the liquid container for volatilizing a liquid held in the liquid container in use.
5. The cartridge according to claim 1 , comprising a heater associated with the receptacle for heating the solid material received by the receptacle in use.
6. The cartridge according to claim 1 , wherein the liquid container has one or more apertures to allow liquid to exit the liquid container.
7. The cartridge according to claim 1 , comprising a wick for wicking liquid held in the liquid container in use out of the liquid container.
8. The cartridge according to claim 1 , wherein the liquid container and the receptacle are provided as an integral component.
9. The cartridge according to claim 1 , wherein the liquid container and the receptacle are provided as separate components which are detachably connected to each other.
10. The cartridge according to claim 1 , wherein the receptacle has at least one retainer for retaining solid material within the receptacle in use.
11. The cartridge according to claim 1 , wherein the receptacle contains the solid material.
12. The cartridge according to claim 11 , wherein the solid material is or comprises tobacco.
13. The cartridge according to claim 1 , wherein the liquid container holds the liquid.
14. A system comprising:
the cartridge according to claim 1 ; and
the apparatus for generating the inhalable medium, the apparatus having a battery section and a mouthpiece, the cartridge being connectable to the apparatus.
15. A method of generating an inhalable medium using a cartridge and an apparatus, wherein the apparatus comprises a battery section and a mouthpiece, and wherein the cartridge comprises a liquid container containing a liquid, a receptacle containing a solid material, and a shell around the outside of the liquid container, wherein the shell and the liquid container define between them a channel, the cartridge being connected to the apparatus, the channel being in the form of a substantially tubular channel which does not completely surround the liquid container, the method comprising:
heating liquid drawn from the liquid container to vaporize the liquid;
passing the vaporized liquid through the channel defined between the liquid container and the shell of the cartridge, into the receptacle containing the solid material and through the solid material so as to entrain at least flavor from the solid material to produce a flavored aerosol; and
passing the flavored aerosol through the mouthpiece of the apparatus.
16. A liquid container for holding a liquid, the liquid container being for use with a receptacle for receiving a solid material to form a cartridge for use with an apparatus for generating an inhalable medium, the liquid container comprising:
an inner container for holding the liquid;
a shell around the outside of the liquid container; and
a connector to enable the liquid container to be connected to the receptacle, wherein the shell and the liquid container define between them a channel, wherein the channel is in the form of a substantially tubular channel which does not completely surround the liquid container.
17. The liquid container according to claim 16 , wherein the connector is in the form of an annular end wall that is receivable in or around the receptacle.
18. The liquid container according to claim 16 , wherein the liquid container has plural of the channels defined between the inner container and the shell.
19. The liquid container according to claim 16 , wherein the liquid container is frustoconical.
20. A method of forming a cartridge for use with an apparatus for generating an inhalable medium, the cartridge comprising a liquid container for holding a liquid, a receptacle for receiving a solid material, and a shell around the outside of the liquid container, wherein the shell and the liquid container define between them a channel, wherein the channel is in the form of a substantially tubular channel which does not completely surround the liquid container, the method comprising:
loading the liquid container with the liquid;
loading the receptacle with solid material; and
connecting the liquid container and the receptacle together, such that in use liquid exiting the liquid container can flow, in the form of at least one of a vapor or an aerosol, through the channel to the receptacle and through solid material received by the receptacle in use.
21. The method according to claim 20 , wherein the loading the receptacle with solid material comprises cutting a rod of the solid material to a desired length and placing the cut rod of solid material into the receptacle prior to connecting the liquid container and the receptacle together.
22. The method according to claim 20 , wherein the solid material is wrapped in a transparent material.
23. The method according to claim 20 , wherein the solid material is or comprises tobacco.
