Abstract

There is disclosed a device for nicotine delivery, comprising: a vapour outlet conduit for coupling to, and for fluid communication with, a vapour creation system, said vapour outlet conduit defining a fluid passage therethrough for delivery of vapour from a vapour creation system to a user; wherein said vapour outlet conduit comprises a nicotine carrier unit region configured to accept a nicotine carrier unit and retain said nicotine carrier unit in said fluid passage. Also disclosed is a system for nicotine delivery and kits-of-parts for assembling the device and system.

First claim

The invention claimed is:

1. A device for delivery of a substance, wherein the substance comprises at least one of nicotine and a flavouring, the device comprising:
a vapour outlet conduit for coupling to, and for fluid communication with, a vapour creation system, said vapour outlet conduit defining a fluid passage therethrough for delivery of vapour from a vapour creation system to a user;
wherein said vapour outlet conduit comprises a substance carrier unit region configured to accept a substance carrier unit and retain said substance carrier unit in said fluid passage,
wherein the vapour outlet conduit comprises penetrating elements for penetrating penetrable seals of the substance carrier unit, such that when the substance carrier unit is located in the fluid passage, the penetrating elements provide a first aperture through which air and/or vapour in a downstream region of the vapour passage can pass and the penetrating elements provide a second aperture through which air and/or vapour in an upstream region of the vapour passage can pass.

2. A device according to claim 1 , wherein said vapour outlet conduit is releasably coupleable to said vapour creation system to permit location of said substance carrier unit in said vapour outlet conduit.

3. A device according to claim 1 , wherein said vapour outlet conduit is separable to permit location of said substance carrier unit therein.

4. A device according to claim 1 , further comprising a substance carrier unit located in said fluid passage, said substance carrier unit configured for removable location within said fluid passage and comprising a substance-bearing substrate configured for entraining the substance in a vapour stream received from said vapour creation system as said vapour stream passes through said vapour outlet conduit.

5. A device according to claim 4 , wherein said substance carrier unit is configured, and located within said vapour outlet conduit, for passage of said vapour stream over said substance-bearing substrate.

6. A device according to claim 4 , wherein said substance carrier unit is configured, and located within said vapour outlet conduit, for passage of said vapour stream through said substance-bearing substrate.

7. A device according to claim 4 , wherein said substance-bearing substrate comprises a porous material where pores of said porous material contain at least one of: nicotine, a nicotine precursor; and a nicotine compound.

8. A device according to claim 7 , wherein said porous material comprises a sintered material.

9. A device according to claim 4 , wherein said substance-bearing substrate comprises polypropylene or polyethylene terephthalate.

10. A device according to claim 4 , wherein said substance carrier unit further comprises a housing for housing said substance-bearing substrate.

11. A device according to claim 10 , wherein said housing defines a passageway in which is located the substance-bearing substrate.

12. A device according to claim 10 , wherein said housing comprises the penetrable seals for closing open ends of said passageway, said penetrable seals penetrable to permit fluid communication through said passageway.

13. A device according to claim 1 , wherein said vapour outlet conduit comprises a mouthpiece of said substance delivery device.

14. A substance carrier unit for a device according claim 1 , wherein said substance carrier unit is configured for removable location within said fluid passage and comprising a substance-bearing substrate configured for releasing a substance to a vapour stream as said vapour stream passes through said vapour outlet conduit, wherein the substance comprises at least one of nicotine and a flavouring, wherein the substance carrier unit comprises a first penetrable seal at a first end of the substance carrier unit and a second penetrable seal at a second end of the substance carrier unit, such that when the substance carrier unit is located within the fluid passage, penetrating elements of the vapour outlet conduit penetrate the penetrable seals, such that the penetrating elements provide a first aperture through which air and/or vapour in a downstream region of the vapour passage can pass and the penetrating elements provide a second aperture through which air and/or vapour in an upstream region of the vapour passage can pass.

15. A system delivery of a substance, wherein the substance is at least one of nicotine and a flavouring, comprising:
a delivery device according to claim 1 ; and
a vapour creation system coupled to said vapour outlet conduit of said delivery device.

16. A kit-of-parts for assembling a device for delivery of a substance, wherein the substance comprises at least one of nicotine and a flavouring, the kit-of-parts comprising:
a vapour outlet conduit configured for coupling to, and for fluid communication with, a vapour creation system, said vapour outlet conduit defining a vapour passage therethrough for delivery of vapour from a vapour creation system to a user, wherein said vapour outlet conduit comprises a substance carrier unit region configured to accept a substance carrier unit and retain said substance carrier unit in said fluid passage, wherein the vapour outlet conduit comprises penetrating elements for penetrating penetrable seals of the substance carrier unit; and
a substance carrier unit configured for removable location in said fluid passage, said substance carrier unit comprising a substance-bearing substrate configured for releasing the substance to a vapour stream as said vapour stream passes through said vapour outlet conduit, wherein the substance carrier unit comprises a first penetrable seal at a first end of the substance carrier unit and a second penetrable seal at a second end of the substance carrier unit, such that when the substance carrier unit is located within the fluid passage, the penetrating elements of the vapour outlet conduit penetrate the penetrable seals, such that the penetrating elements provide a first aperture through which air and/or vapour in a downstream region of the vapour passage can pass and the penetrating elements provide a second aperture through which air and/or vapour in an upstream region of the vapour passage can pass.

17. A kit-of-parts for assembling a system for delivery of a substance, wherein the substance comprises at least one of nicotine and a flavouring, the kit-of-parts comprising:
a vapour outlet conduit configured for coupling to, and for fluid communication with, a vapour creation system, said vapour outlet conduit defining a vapour passage therethrough for delivery of vapour from a vapour creation system to a user, wherein said vapour outlet conduit comprises a substance carrier unit region configured to accept a substance carrier unit and retain said substance carrier unit in said fluid passage, wherein the vapour outlet conduit comprises penetrating elements for penetrating penetrable seals of the substance carrier unit;
a substance carrier unit configured for removable location in said fluid passage, said substance carrier unit comprising a substance-bearing substrate configured for releasing the substance to a vapour stream as said vapour stream passes through said vapour outlet conduit, wherein the substance carrier unit comprises a first penetrable seal at a first end of the substance carrier unit and a second penetrable seal at a second end of the substance carrier unit, such that when the substance carrier unit is located within the fluid passage, the penetrating elements of the vapour outlet conduit penetrate the penetrable seals, such that the penetr
