Abstract
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.
