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.

Claims

1. An e-liquid system comprising a user-replaceable e-liquid cartridge, a portable, personal storage and carrying case for an e-liquid e-cigarette PV and an electrical or electronic pump positioned in the case, in which the user-replaceable e-liquid cartridge is configured to be inserted into or attached to the case to operatively engage with the electrical or electronic pump when inserted or attached to the case, the pump delivering a pre-defined or variable quantity of e-liquid from the cartridge.

2. The e-liquid system of claim 1 in which 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.

3. The e-liquid system of claim 1 in which the cartridge has a casing that is configured to be fitted by a user into a chamber in the portable, personal storage and carrying case.

4. The e-liquid system of claim 1 in which the cartridge has an outer surface that forms part of the casing of the case or an extension to the case, with case and cartridge when combined forming an object that in normal use can be stored in a pocket.

5. The e-liquid system of claim 1 in which the e-liquid capacity of the user replaceable cartridge is at least three times greater than the e-liquid capacity of an e-liquid chamber in the PV.

6. The e-liquid system of claim 1 configured to engage with the pump that delivers e-liquid into the PV approximately equivalent to a single cigarette for each pumping stroke.

7. The e-liquid system of claim 1 in which the e-liquid cartridge is designed in normal use to permit e-liquid to escape from the cartridge only if the cartridge is correctly positioned in or attached to the case.

8. The e-liquid system of claim 1 in which the cartridge is not substantially deformable in normal use in order to displace fluid from the cartridge.

9. The e-liquid system of claim 1 in which the e-liquid cartridge is designed to slot inside or against the case with a press fit against a seal and in which the cartridge is formed with a void designed to receive and engage with a micro-pump that is positioned in the case, the micro-pump sealing against a nozzle or aperture in the cartridge.

10. The e-liquid system of claim 1 in which the cartridge includes an integral micro-pump.

11. The e-liquid system of claim 1 in which the cartridge 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.

12. The e-liquid system of claim 1 said cartridge, being one of several cartridges inserted in or attached to the case, in which the case is operable to select a specific desired cartridge or to mix e-liquid from several cartridges.

13. The e-liquid system of claim 1, said cartridge including several compartments, each with a different e-liquid.

14. The e-liquid system of claim 1, said cartridge including which includes an electronic identifier.

15. The e-liquid system of claim 1, said cartridge being that is configured to be removed and replaced with a replacement e-liquid cartridge in normal use by an end-user.

16. The e-liquid system of claim 15, said cartridge or replacement e-liquid cartridge comprising e-liquid with a flavour or nicotine strength selected from a range of different available flavours or nicotine strengths.

17. The e-liquid system of claim 1, said cartridge configured to detect or infer the level or quantity of e-liquid in the cartridge and send a corresponding signal indicating that a replacement cartridge is needed.

18. The e-liquid system of claim 17 in which the signal is sent to a connected smartphone which in turn connects to an e-fulfilment platform.

19. The e-liquid 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.

20. A method for sending a signal relating to the status of a user-replaceable e-liquid cartridge according to claim 1 used in a portable, personal storage and carrying case configured specifically for a refillable e-cigarette PV and that re-fills and re-charges the PV, the method including the steps of (a) transferring e-liquid from a 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-fulfilment platform, either directly or via a connected smartphone.

21. The method of claim 20 including the steps of the case (a) detecting the level of or quantity of e-liquid in a user-replaceable e-liquid cartridge in the case and (b) automatically sending a signal requesting a replacement for the user-replaceable e-liquid cartridge to an e-fulfilment platform, either directly or via a connected smartphone.
