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, in which the case includes a hinged compartment that the PV is slotted into, and which guides an aperture of the PV into contact with a pump nozzle that fills a chamber in the PV with e-liquid.

Claims

1. 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, whilst maintaining the PV whole and intact

wherein the case includes a hinged compartment that the PV is slotted into, and which guides an aperture of the PV into contact with a pump nozzle that fills a chamber in the PV with e-liquid.

2. The case of claim 1 which is adapted to transfer e-liquid to an e-cigarette PV from a user-replaceable e-liquid cartridge in or attached to the case.

3. The case of claim 2 in which the case includes a nozzle or aperture operable to engage with a micro-pump formed in the e-liquid cartridge inserted into or attached to the case.

4. The case of claim 1 which re-fills the PV using a fluid transfer system, whilst the PV is held in a holder of the case in accurate alignment with a fluid transfer mechanism.

5. The case of claim 1 in which a fluid transfer system is a pump activated by moving the entire, complete PV relative to the pump.

6. The case of claim 1 in 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.

7. The case of claim 1 which is operable to re-fill and re-charge the PV, without the need to dis-assemble or puncture the PV, via an e-liquid filling aperture or nozzle formed in one end of a mouthpiece, the e-liquid filling nozzle being separate from a vapour inhalation nozzle(s).

8. The case of claim 1 in which the PV includes an e-liquid filling aperture or nozzle positioned centrally along a main axis of the PV to minimise any off-centre forces that could otherwise compromise e-liquid and the case guides that aperture or nozzle into accurate alignment with a fluid transfer mechanism.

9. The case of claim 8 in which the aperture or nozzle aligns with a hollow tube or shaft that is part of a pump and the aperture or nozzle includes a flexible seal through which the tube or shaft is inserted, the seal ensuring that any drips of e-liquid are retained within the PV.

10. The case of claim 8 in which a tip of the PV includes a fluid trap and absorbent wicking to capture any fluid leakage.

11. The case of claim 1 in which a hollow e-liquid filing tube or shaft extends up from the central axis of a pump against which the PV is positioned.

12. The case of claim 1 in which the PV re-fills using a pump activated by depressing and releasing the entire, complete PV whilst the PV is held in a hinged compartment of the case and the PV can slide up and down in the compartment.

13. The case of claim 1 in which the PV is re-filled by a mechanical camming action caused by the top of the PV being pressed or cammed downwards when it is closed inside a carrying case, the camming action depressing the PV so that it completes a downstroke of a pumping action.

14. The case of claim 1 in which the case automatically re-fills and re-charges an e-cigarette PV, the case including a hinged compartment that the PV is slotted into, mouthpiece end downwards, and which, whenever the hinged compartment is closed, cams the PV downwards to prime or activate a pump nozzle that will deliver e-liquid from a cartridge into a chamber in the PV until the pressure in the chamber equals the pressure in an e-liquid cartridge in the case.

15. The case of claim 1 in which the case the case includes a micro-pump designed to slot into or be received by an aperture in an e-liquid cartridge.

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

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

18. The case of claim 1 in which the case includes several user-removable e-liquid cartridges and can fill the PV by combining e-liquid from several cartridges.

19. The case of claim 1 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.

20. The case of claim 1 in which the user-replaceable cartridge includes physical features on its surface that physically engage with complimentary features in the wall of the case aperture into which the cartridge is inserted.

21. The case of claim 20 in which the physical features form the shape of a word or logo.

22. The case of claim 21, wherein the word or logo comprises a trademarked word or logo.

23. The case of claim 20, wherein the physical features comprise raised or lowered portions.

24. The case of claim 1 in which the if the PV is pumped just once, then the case transfers e-liquid approximately equivalent to a single cigarette to the PV and if the PV is pumped five times then the case transfers e-liquid approximately equivalent to five cigarettes.

25. 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.

26. A portable, personal storage and carrying case for an e-liquid e-cigarette PV in which the case is adapted to transfer e-liquid to an e-cigarette PV from a user-replaceable e-liquid cartridge in the case

wherein the case includes a hinged compartment that the PV is slotted into, and which guides an aperture of the PV into contact with a pump nozzle that fills a chamber in the PV with e-liquid.

27. A portable, personal storage and carrying case for an e-liquid e-cigarette PV which re-fills the PV using a fluid transfer system, for example, a pump activated by moving relative to the pump the entire, complete PV, whilst the PV is held in a holder of the case in accurate alignment with a fluid transfer mechanism

wherein the case includes a hinged compartment that the PV is slotted into, and which guides an aperture of the PV into contact with a pump nozzle that fills a chamber in the PV with e-liquid.
