A practically diffusion-tight container which is capable of being stored over long periods of time and with which the liquid does not come into contact with the ambient air is required for withdrawing a liquid in a dosed manner out of the same over a duration of several months. The inventive cartridge is a container which is comprised of three shells and which can consist of a collapsible bag containing the liquid, of a dimensionally stabile container, and of a stiff metal shell. The cartridge can be detachably connected to a withdrawing device. The cartridge can be provided with a micro-opening with which the time for the pressure compensation between the cartridge and the surroundings can be adjusted. The cartridge is suited for aqueous and alcoholic liquids which contain a pharmacologically active ingredient. The liquid in the cartridge is protected against external influences. The cartridge can be used in an atomizer for generating an aerosol which can be inhaled and which is provided for treating illnesses.
Pour prélever d'un contenant stockable sur une longue période un liquide dosé pendant plusieurs mois, il faut un contenant qui soit pratiquement imperméable à la diffusion et qui assure que le liquide n'entre pas en contact avec l'air ambiant. La cartouche selon l'invention est un contenant à trois coques pouvant être constitué d'une poche flexible renfermant le liquide, d'un contenant indéformable et d'une enveloppe métallique rigide. La cartouche peut être raccordée de façon amovible à un appareil de prélèvement. La cartouche peut être dotée d'un micro-orifice qui permet de régler le temps de compensation de pression entre la cartouche et l'environnement. La cartouche est adaptée aux liquides aqueux et alcooliques contenant un principe pharmaceutiquement actif. Le liquide contenu dans la cartouche est protégé de toute influence extérieure. La cartouche peut être utilisée dans un pulvérisateur destiné à la production d'un aérosol inhalable destiné au traitement de maladies.
