Reservoir assembly for a personal vaporizer device

1. A reservoir assembly for a personal vaporizer device, such as an electronic smoking article, comprising:

a housing which encloses a reservoir for storing a liquid to be vaporized, the housing and/or the reservoir defining a flow path for the liquid from the reservoir towards a vaporizer; and

a mouthpiece provided in or on the housing and defining a channel for conveying vapour formed from the liquid to a user's mouth;

wherein the mouthpiece is configured for movement between a first position and a second position, and wherein the flow path is closed or blocked when the mouthpiece is in the first position and wherein the flow path is open in the second position,

wherein a part of the mouthpiece blocks the flow path in the first position, and

wherein the reservoir surrounds a central cavity in the housing; and wherein the central cavity accommodates the mouthpiece.

2. The reservoir assembly according to claim 1 , wherein the flow path comprises a flow port formed in a wall of the reservoir, and wherein the mouthpiece comprises a sealing portion which covers or blocks the flow port when the mouthpiece is in the first position.

3. The reservoir assembly according to claim 1 , wherein the mouthpiece is configured to be substantially retracted into the housing in the first position.

4. The reservoir assembly according to claim 1 , wherein the mouthpiece is configured to extend or project from the housing in the second position.

5. The reservoir assembly according to claim 1 , wherein the mouthpiece comprises an elongate member having the channel extending longitudinally thereof, and wherein the mouthpiece is movable in the longitudinal direction between the first position and the second position.

6. The reservoir assembly according to claim 1 , wherein the mouthpiece is resiliently biased towards the first position.

7. The reservoir assembly according to claim 1 , wherein the mouthpiece is configured for translational or sliding movement between the first position and the second position.

8. The reservoir assembly according to claim 1 , wherein the mouthpiece is configured for rotational movement between the first position and the second position.

9. The reservoir assembly according to claim 1 , wherein the housing is configured to receive, at least partially, an aerosol generating means of the personal vaporizer device,

wherein the mouthpiece is configured for movement from the first position to the second position when the aerosol generating means is inserted into or received in the housing, and

wherein the mouthpiece is configured for movement from the second position to the first position when the aerosol generating means is removed or withdrawn from the housing.

10. A personal vaporizer device, especially an e-cigarette, comprising:

the reservoir assembly according to claim 1 ; and

a vaporizer; and

a power supply for powering the vaporizer to vaporize the liquid from the reservoir.

11. The personal vaporizer device according to claim 10 , wherein the housing is configured to receive, at least partially, the vaporizer of the personal vaporizer device, and

wherein the mouthpiece is configured for movement from the first position to the second position upon insertion of the vaporizer into the housing.

12. The personal vaporizer device according to claim 10 , wherein the power supply is a battery unit and includes a casing configured for connection with the housing of the reservoir assembly, wherein the casing is configured for connection with the housing in a friction fit or in a threaded or a latched connection.

13. The reservoir assembly according to claim 6 , wherein the mouthpiece is resiliently biased towards the first position by spring means.
