In order to be able automatically to effect the opening of the inner closure (7), but in particular its closure, when the storage container (1) has been substantially emptied and in order to be able to remove the inner closure without problems for the purpose of rinsing and refilling of the storage container (1), and to do so having regard to its reusability, the liquid dispenser according to the invention is constructed in such a way that the inner closure (7) is constructed, towards the outflow side, as an open sleeve (7') and the latter is equipped with a thread (11) capable of being screwed onto the opening spigot (2) of the holder (3) and having a pitch (S) acting in the same direction as the thread (5) of the connecting neck (6), and the pitch (S) of the threads (11, 11') of the sleeve (7'') and of the opening spigot (2) is smaller than the pitch (S) of the threads (5, 5') of the connecting neck (6) and of the associated holder (3). <IMAGE>
