A user-replaceable e-liquid reservoir for dispensing e-liquid, the reservoir being inserted into, or otherwise attached to, a portable, personal e-cigarette device and engaging with an electrical or electronic pump fluid transfer system in the device, the device including: an electrical or electronic pump, being configured to transfer e-liquid from the e-liquid reservoir to an atomizing unit in the device, the pump delivering a pre-defined or variable quantity of e-liquid from the reservoir; and in which the reservoir is not user-refillable.

A case for an electronic cigarette vaporiser, the case including an automatic lifting mechanism that lifts the vaporiser up a few mm from the case to enable a user to easily grasp the vaporiser and withdraw it from the case. The lifting mechanism can be spring- based. The case both re-fills the vaporiser with liquid and also re-charges a battery in the vaporiser.

An e-cigarette PV that includes an air pressure valve or device so that excess air can escape from an e-liquid reservoir in the PV when that reservoir is being filled under pressure with e-liquid from a parent reservoir. The valve or device is a barrier made of an air-porous material, such as a sintered polymer or metal, coated with or otherwise including a barrier or layer of an air-porous substance that is not porous to e-liquid, such as an oleophobic material or a hydrophobic or super-hydrophobic material. The oleophobic material is one of: sintered phosphor bronze, sintered stainless steel and sintered PU plastic.

A re-fillable liquid tip or pod for a vaping device that includes capacitive sensor plates in the tip liquid reservoir. A liquid re-filling device provides liquid to the vaping device, drawn from a refill bottle; the re-filling device includes a capacitance measuring circuit; a microcontroller uses the data from the capacitance measuring circuit to determine if the level of liquid in the tip liquid reservoir is above or below a threshold level; if below, then a liquid pump in the re-filling device is activated to draw liquid from the refill bottle and pump it through the vaping device and up into the tip liquid reservoir. Pumping ceases once the liquid reaches the threshold level.

An e-liquid cartridge or other form of parent reservoir designed to supply e-liquid to an electronic cigarette vaporiser, in which the cartridge includes an air pressure valve. The air pressure valve is designed so that as the fluid level inside the cartridge/reservoir falls, atmospheric pressure enables the air pressure valve to allow air to flow into the cartridge/reservoir and ensure equalisation of the air pressure. The valve is an air-porous e-liquid impermeable PTFE or PTFE-coated layer or membrane.
