A device for distributing substances includes distribution container (1) receiving a substance. The container has a closing unit (3) provided with a canula (11) for the substance to be distributed. The outer end (15) of the canula protrudes from the closing unit (3). A safety device (5, 17) can alternate between a protective state in which it covers the outer end (15) of the canula (11), and a user state for the distribution of the substance from the canula (11).
