Abstract: A cartridge for an electronic cigarette or a portable inhaler has a rigid reservoir for receiving a liquid. The reservoir has at least one extraction opening which is configured to enable the extraction of liquid from the reservoir. The reservoir has one or more pressure regulation elements in an interior of the reservoir which are arranged in a wall of the reservoir and through which no exit of liquid from the reservoir is possible. The pressure regulation elements are selected independently of one another from the list comprising non-return valves, gas-permeable but liquid-impermeable diaphragms, and deformable wall portions.

Abstract: A vaporizer cartridge of an inhaler has a liquid storage tank and a hollow body with a continuous air flow channel. The storage tank has an access opening to the air flow channel. A vaporizer unit extends over the entire access opening and is arranged in the region of the access opening. The vaporizer unit has a wick member towards the storage tank and a heating member towards the air flow channel. The vaporizer unit is liquid-permeable such that liquid is conveyed at least initially from the tank through the vaporizer unit to the channel in a capillary manner. The interior of the tank is structurally divided into fluidically coupled main and auxiliary volume. Only the auxiliary volume is in direct contact with the vaporizer unit, such that the liquid from the main volume contacts the wick member solely via the auxiliary volume. An inhaler may include the vaporizer cartridge.

Abstract: A consumption unit for an inhaler comprises a liquid reservoir, a vaporizer device arranged in the liquid reservoir, and a vent having a flow channel extending in the liquid reservoir to a flow connection of the flow channel to the environment. The liquid reservoir comprises a filling opening, which is closed by means of a first closure part.

Abstract: A vaporizer tank unit for an inhaler, preferably an electronic cigarette product comprises at least an electric vaporizer for vaporizing liquid fed to the vaporizer, a liquid reservoir for storing liquid, and a capillary wick structure, wherein the liquid is feedable by capillary forces from the liquid reservoir to an inlet side of the vaporizer. The wick structure is one-piece and contacts and/or forms the liquid reservoir over at least one circumferential section.
