Foil bags are used as a primary packaging for liquids, the bags permitting the liquid to be taken therefrom without the application of a considerable amount of force. A container is provided for a medicinal liquid, the container being gas-tight and liquid-tight so that it is storable over many months. The container includes a collapsible foil bag on which a flange, which is stable in respect of shape, is disposed. The flange is designed for fitting onto a discharge connection member. The container can be disposed in a casing which is stable in respect of shape. The medicinal liquid does not come into contact with air and is protected from the effect of light. The medicinal liquid may be dispensed from the foil bag in many partial quantities over a prolonged period of time, with a respective partial amount thereof being converted into an aerosol by means of an atomizer.
