At least the portion of said storage element which is connected to the inlet opening is dimensioned to have a capillary effect on a liquid contained in the storage element so as to leave a gas pocket free between the liquid and the inlet opening, whereby a displacement of the liquid in the storage element can be impeded when the dispensing device is shaken. Preferably the storage element consists of a wound piece of hose or tubing having at least one and preferably two or three turns.
