Mouthpiece

1. An apparatus for generating an inhalable medium, the apparatus comprising a mouthpiece comprising:

an aperture extending from a first opening at a first end of the mouthpiece to a second opening at an opposing end of the mouthpiece, wherein the first opening is at a mouth end of the mouthpiece and the second opening is at an apparatus end of the mouthpiece, the mouthpiece being arranged to receive in the aperture through the first opening a flavor element for imparting a flavor to a flow of at least one of a vapor or an aerosol that passes through the mouthpiece in use, the aperture having a first radial dimension towards the first opening and a second radial dimension towards the second opening, wherein the second radial dimension is smaller than the first radial dimension, and

the flavor element for imparting a flavor to a flow of at least one of a vapor or an aerosol that passes through the mouthpiece in use, wherein the flavor element is received in the aperture of the mouthpiece through the first opening, wherein the flavor element protrudes beyond the first opening.

2. The apparatus of claim 1 , wherein the aperture is or comprises a stepped bore, the stepped bore comprising a first bore portion having the first radial dimension and a second bore portion having the second radial dimension.

3. The apparatus of claim 1 , wherein the mouthpiece comprises, at the second opening, a chamfer for engaging with a component of the apparatus.

4. The apparatus for generating an inhalable medium of claim 1 , further comprising:

a container for holding a liquid; and

a heater for volatilizing liquid held in the container to generate the flow of at least one of a vapor or an aerosol in use;

wherein in use the flow of the at least one of the vapor or the aerosol passes through the flavor element for inhalation by a user.

5. The apparatus of claim 4 , wherein the container for holding liquid comprises a recess into which the flavor element is received.

6. The apparatus of claim 1 , wherein the apparatus end of the mouthpiece is arranged to be releasably connected to the apparatus.

7. The apparatus of claim 1 , further comprising a wall and wherein the flavor element engages the wall and the wall surrounds the flavor element.

8. The apparatus of claim 1 , wherein the flavor element comprises nicotine.

9. The apparatus of claim 1 , wherein the flavor element comprises tobacco.

10. The apparatus of claim 9 , wherein the flavor element comprises a rod or plug of tobacco.

11. The apparatus of claim 1 , wherein the flavor element comprises a material wrapped partially or wholly in a wrapper.

12. An apparatus for generating an inhalable medium, the apparatus comprising a mouthpiece comprising:

an aperture extending from a first opening at a first end of the mouthpiece to a second opening at an opposing end of the mouthpiece, wherein the first opening is at a mouth end of the mouthpiece and the second opening is at an apparatus end of the mouthpiece, the mouthpiece being arranged to receive in the aperture through the first opening a flavor element for imparting a flavor to a flow of at least one of a vapor or an aerosol that passes through the mouthpiece in use, the aperture having a first radial dimension towards the first opening and a second radial dimension towards the second opening, wherein the second radial dimension is smaller than the first radial dimension,

a container for holding a liquid; and

a heater for volatilizing liquid held in the container to generate the flow of at least one of a vapor or an aerosol in use, and

the flavor element for imparting a flavor to a flow of at least one of a vapor or an aerosol that passes through the mouthpiece in use, wherein the flavor element is received in the aperture of the mouthpiece through the first opening,

wherein in use the flow of the at least one of the vapor or the aerosol passes through the flavor element for inhalation by a user, and

wherein the container for holding liquid comprises a recess into which the flavor element is received.
