Abstract

A portable, personal storage and carrying case for an e-liquid e-cigarette PV in which the case includes a movable holder or chassis into which the PV can be inserted to bring electrical charging contacts on the PV into direct or indirect engagement with electrical charging contacts in the case that are connected to a power source in the case.

First claim

The invention claimed is:

1. A portable, personal storage and carrying case for an e-liquid e-cigarette PV in which the case includes:
(a) a power source;
(b) electrical charging contacts connected to the power source;
(c) a user-replaceable e-liquid cartridge;
(d) an electrical, mechanical or piezoelectric pump; and
(e) a movable holder or chassis into which the PV can be inserted to bring electrical charging contacts on the PV into direct or indirect engagement with the electrical charging contacts in the case that are connected to the power source in the case.

2. The case of claim 1 in which the holder also has mounted on it the e-liquid cartridge the power source a printed circuit board and a fluid transfer mechanism.

3. The case of claim 1 in which the holder pivots about a screw or other form of axis in the case.

4. The case of claim 3 in which the holder is formed as a trigger, so that a user closing his grip on one part of the holder causes the holder to open from the case, enabling a PV stored in the case to be withdrawn from the case.

5. The case of claim 1 in which the holder includes a channel into which the PV can slide, the channel guiding the PV into the position needed for accurate re-filling with e-liquid.

6. The case of claim 5 in which the channel enables the PV to be moved up and down relative to the pump, acting as the stroke which causes the pump to transfer e-liquid from a reservoir in the case to a chamber in the PV.

7. The case of claim 1 in which the holder is 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.

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

9. The case of claim 1 in which the holder is 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 e-liquid cartridge into a chamber in the PV until the pressure in the chamber equals the pressure in the e-liquid cartridge in the case.

10. The case of claim 1 in which the holder has to be fully closed to bring the electrical charging contacts on the PV into direct or indirect engagement with electrical charging contacts in the case.

11. The case of claim 1 in which the movable holder has to be partly closed to bring the electrical charging contacts on the PV into direct or indirect engagement with electrical charging contacts in the case.

12. The case of claim 1 which is operable to re-fill the PV using a fluid transfer system comprising the pump activated by moving relative to the pump the entire, complete PV, whilst the PV is held in the holder.

13. The case of claim 1 in which the holder is a side-loading holder.

14. The case of claim 1 in which the holder is manually moved.

15. The case of claim 1 in which the holder is moved using one or more motors.

16. 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.
