Abstract

A portable, personal storage and carrying case for an e-liquid e-cigarette PV which is operable to re-fill the PV with e-liquid if the PV is inserted, fully or in part, into the case, while maintaining the PV whole and intact. The case includes an electrical power source recharging a battery in the PV, a user-replaceable reservoir for the e-liquid, and an electrical or electronic pump delivering a predefined or variable quantity of e-liquid from the cartridge.

Claims

1. A portable, personal storage and carrying case for an e-liquid e-cigarette PV in which the case includes:

(a) an electrical power source for re-charging a rechargeable battery in the PV;

(b) a user-replaceable reservoir for holding e-liquid; and

(c) an electrical or electronic pump adapted to transfer e-liquid from the reservoir to a chamber in the PV, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir.

2. The case of claim 1 in which the e-liquid includes nicotine and the PV is not a medicinal device but instead a device that in normal use replaces cigarettes, with the e-liquid being vapourised in the PV and the vapour inhaled to replicate or replace the experience of smoking a cigarette.

3. The case of claim 1 in which the user-replaceable reservoir for holding e-liquid is a user-replaceable e-liquid cartridge.

4. The case of claim 3 in which the user-replaceable e-liquid cartridge fits in the case or is attached to the case.

5. The case of claim 3 in which the user-replaceable e-liquid cartridge is designed in normal use to permit e-liquid to escape only if the cartridge is correctly positioned in the case.

6. The case of claim 3 in which the e-liquid capacity of the user replaceable cartridge is at least three times greater than the e-liquid capacity of the chamber in the PV.

7. The case of claim 3 in which the case includes an overflow channel that enables excess e-liquid that is pumped up from the cartridge but is not stored in the PV to be captured and returned to the cartridge.

8. The case of claim 3 which includes a data processor that controls sending a signal requesting a replacement for the user-replaceable e-liquid cartridge in the case.

9. The case of claim 8 in which the case or the user-replaceable cartridge detects the level of e-liquid or the quantity of e-liquid in the user-replaceable cartridge.

10. The case of claim 8 in which the signal is sent to a connected smartphone which in turn connects to an e-fulfillment platform.

11. The case of claim 1 including a fluid transfer system adapted to transfer e-liquid from the case to the chamber in the PV, in which the fluid transfer system includes the electrical or electronic pump that delivers e-liquid approximately equivalent to a single cigarette for each pumping stroke.

12. The case of claim 1 which can be locked or disabled to prevent under-age or unauthorised use using data sent or exchanged with a smartphone or an authorized user.

13. The case of claim 1 in which moving a movable holder or chassis, into which the PV has been inserted, brings electrical charging contacts on the PV into direct or indirect engagement with electrical charging contacts in the case that are connected to the electrical power source.

14. The case of claim 13 in which the movable chassis also has mounted on it the e-fluid reservoir, a battery, a printed circuit board and a fluid transfer mechanism.

15. The case of claim 1 which is operable to re-fill the PV with e-liquid if the PV is inserted, fully or in part, into the case, whilst maintaining the PV whole and intact.

16. The case of claim 1 which is operable to re-fill the PV with e-liquid if the PV is inserted, fully or in part, into the case without the need to dis-assemble or puncture the PV, maintaining the PV whole and intact.

17. The case of claim 1 in which a hollow e-liquid filling tube or shaft extends up from a central axis of a hollow compartment into which the PV is inserted.

18. The case of claim 1 in which the PV re-fills using a fluid transfer system in which the PV moves relative to the electrical or electronic pump in the case.

19. The case of claim 1 in which the case includes a hinged compartment that the PV is slotted into, mouthpiece end downwards, and which guides an aperture of the PV into contact with a pump nozzle that fills the chamber in the PV with e-liquid until the pressure in the chamber in the PV equals the pressure in an e-liquid cartridge in the case.

20. The case of claim 1 in which the electrical or electronic pump is a micro-pump designed to slot into an aperture in the user-replaceable reservoir for holding e-liquid, which is an e-liquid cartridge.

21. The case of claim 1 in which the electrical or electronic pump is a micro-pump, and in which the case includes a nozzle or aperture operable to engage with the micro-pump which is formed in the user-replaceable reservoir for holding e-liquid, which is an e-liquid cartridge.

22. The case of claim 1 in which the case is adapted to lock the PV securely in a charging position;

and when the PV is locked in the charging position, then electrical charging contacts on the PV are in direct or indirect engagement with electrical charging contacts in the case that are connected to the electrical power source in the case.

23. The case of claim 22 in which the case automatically charges the PV only if the PV is fully inserted and an inter-lock operates to secure the PV in position.

24. The case of claim 22 in which the case automatically locks the e-cigarette PV into a secured re-charging position when the case is fully closed for storage and carrying the PV.

25. The case of claim 1 in which the user-replaceable reservoir is a user-removable e-liquid cartridge and the combination of cartridge and case forms in normal use a portable, personal device for the storage and carrying of the PV and its re-filling with e-liquid.

26. The case of claim 1 in which the case can fill the PV by combining e-liquid from several different e-liquid compartments.

27. The case of claim 1 in which the case includes several user-removable e-liquid cartridges and the case can fill the PV by combining e-liquid from several cartridges, wherein the user-replaceable reservoir is a first user-removeable e-liquid cartridge of the several user-removeable e-liquid cartridges.

28. The case of claim 1 which starts providing power to heat an electrical atomising element in a PV automatically when the case in which the PV is stored is opened.

29. The case of claim 1 which includes a locking system to lock the PV securely in a heating position during which time the PV is heating using power from a power source in the case and, after the PV has been sufficiently heated, to release the locking system.

30. The case of claim 29 in which the case automatically moves the PV to a position which allows it to be readily removed from the case by an end-user once the PV has been sufficiently heated.

31. The case of claim 1 in which the user presses the PV down when it is locked securely in a heating position in the case to initiate heating.

32. A method used in portable, personal storage and carrying case adapted specifically for a refillable e-cigarette PV and that re-fills and re-charges the PV, in which the case includes:

(i) an electrical power source for re-charging a rechargeable battery in the PV;

(ii) a user-replaceable e-liquid cartridge for holding e-liquid; and

(iii) an electrical or electronic pump adapted to transfer e-liquid from the e-liquid cartridge to a chamber in the PV, the pump delivering a pre-defined or variable quantity of e-liquid from the cartridge,

the method including the steps of the case (a) transferring e-liquid from the user-replaceable e-liquid cartridge to the PV and (b) automatically sending a signal requesting a replacement for the user-replaceable e-liquid cartridge to an e-fulfillment platform, either directly or via a connected smartphone.

33. The method of claim 32 including the step of detecting the level of or quantity of e-liquid in the user-replaceable e-liquid cartridge in the case.

34. A user-replaceable e-liquid reservoir for dispensing e-liquid, inserted into a portable, personal storage and carrying case for an e-liquid e-cigarette PV and engaging with an electrical or electronic pump fluid transfer system in the case, the case including:

(a) an electrical power source for re-charging a rechargeable battery in the PV; and

(b) the electrical or electronic pump, being configured to transfer e-liquid from the e-liquid reservoir to a chamber in the PV, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir.
