A cartridge and a nebulizer for nebulizing a fluid as well as a method for fluidically connecting the cartridge to the nebulizer are proposed. The cartridge comprises a closure with a valve, wherein the valve displaces fluid into the nebulizer when opened. Further, the cartridge forms two axially spaced sealings with the nebulizer when connected.

Nebulizer and cartridge

A method for producing a cartridge is proposed, where a fluid is filled into an opening of a container and a closure part is inserted into the container, thereby moving a movable piston arranged within the container.

Method for producing a cartridge

A nebulizer for nebulizing a fluid from a cartridge and a cartridge for such a nebulizer is proposed. The cartridge comprises a container containing the fluid to be nebulized and is fluidically connected to the nebulizer by inserting a connecting element of the nebulizer for conveying the fluid out of the container. The cartridge is preferably adapted to sealingly receive the connecting element and can optionally comprise a membrane or sealing wall which seals the cartridge initially and is piercable or breakable by the connecting element upon insertion. The cartridge can further comprise an at least partially flexible and/or bendable tube for conveying the fluid out of the container. The tube is preferably wettable with the fluid and/or comprises an at least partially hydrophilic and/or polar surface. Further, the tube can at least partially be shaped as a helix. When the cartridge is connected to the nebulizer, the tube and the connecting element preferably form a continuous capillary and/or an at least essentially constant flow area.

A container, a nebulizer and a use of an indicator device are described, where the container comprises an indicator device fixedly mounted on the bottom of the container, the container is arranged within the nebulizer and the container can be detached by grabbing the indicator device.
