Abstract

A re-fillable and re-chargeable e-cigarette PV that is not disassembled in normal use for re-filling or replenishing with e-liquid and is also not disassembled in normal use for battery access or replacement or other battery interaction.

First claim

The invention claimed is:

1. A re-fillable and re-chargeable e-cigarette system including (a) a PV that is not disassemblable in normal use for re-filling or replenishing with e-liquid and is also not disassemblable in normal use for battery access or replacement or other battery interaction, and (b) a case that is specifically adapted to both re-fill or replenish the PV with e-liquid and also to re-charge the battery, wherein the PV is insertable into the case for the PV and wherein the PV is re-filled or replenished from a user-replaceable e-liquid cartridge in the case.

2. The e-cigarette system of claim 1 in which the PV includes a rechargeable battery, re-fillable e-liquid reservoir and an atomiser, all contained within a casing, and none of which are removable from, or separable from, any part of the casing in normal use.

3. The e-cigarette system of claim 1 in which the PV includes an e-liquid filling aperture positioned centrally along the main axis of the PV to minimise any off-centre forces that could otherwise compromise e-liquid sealing.

4. The e-cigarette system of claim 1 in which the PV is adapted to slot or engage with the case that re-fills and re-charges the PV, without the need to dis-assemble or puncture the PV, maintaining the PV whole and intact.

5. The e-cigarette system of claim 1 in which the case re-fills and re-charges the PV, without the need to dis-assemble or puncture the PV, via an e-liquid filling nozzle formed in one end of a mouthpiece, the e-liquid filling nozzle being separate from vapour inhalation nozzle(s).

6. The e-cigarette system of claim 1 in which an aperture in the PV aligns with a hollow tube or shaft that is part of a pump and the aperture includes a flexible seal through which the tube is inserted, the seal ensuring that any drips of e-liquid are retained within the PV.

7. The e-cigarette system of claim 1 in which a tip of the PV includes a fluid trap and absorbent wicking to capture any fluid leakage.

8. The e-cigarette system of claim 1 in which a hollow tube or shaft extends up from the central axis of a hollow compartment into which the PV is inserted.

9. The e-cigarette system of claim 1 in which the PV re-fills using a fluid transfer system in which the PV moves relative to a pump.

10. The e-cigarette system of claim 9 in which the PV re-fills using the pump activated by depressing and releasing the entire, complete PV whilst the PV is held in a holder, the PV sliding up and down within the holder.

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

12. The e-cigarette system of claim 1 in which the PV is filled by a motor moving the PV up and down in relation to a pump, or the pump in relation to the PV.

13. The e-cigarette system of claim 1 in which the PV is adapted to slot or engage with the case that 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 a chamber in the PV with e-liquid until the pressure in the chamber equals the pressure in the e-liquid cartridge in the case.

14. The e-cigarette system of claim 1 in which the PV is adapted to slot or engage with the case that automatically re-fills and re-charges the 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 the cartridge into a chamber in the PV until the pressure in the chamber equals the pressure in the e-liquid cartridge in the case.

15. The e-cigarette system of claim 1 in which the case automatically re-fills an e-cigarette PV via an e-liquid nozzle at the centre of a mouthpiece end of the PV from the user-replaceable e-liquid cartridge in the case, the case including a micro-pump designed to slot into or be received by an aperture in the cartridge.

16. The e-cigarette system of claim 1 in which a nozzle or aperture in the PV engages with a micro-pump formed in the user-replaceable e-liquid cartridge.

17. The e-cigarette system 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.

18. The e-cigarette system of claim 1 in which the PV is designed to be withdrawn from the case prior to re-filling and then inserted against a nozzle in the case for re-filling.

19. The e-cigarette system of claim 1 wherein the case is a portable charging and refilling case.

20. The e-cigarette system of claim 1 wherein the case is a fixed, desktop charging and refilling station.
