Abstract: A method of dispensing ingestible units such as capsules, tablets and pills in such manner as to avoid tampering or adulteration comprises packaging such units in sealable containers, sealing the containers, and loading the sealed containers into a magazine at the factory where the units are produced. The sealed magazine is transported to the place of sale where it is inserted, while still sealed, into the housing of dispensing apparatus having an opening for introducing the magazine, a closure for the opening and a lock for securing the closure. Moreover, the apparatus includes blades for breaking the seal of the magazine when inserted to release the containers and mechanism for sequentially dispensing the containers in such manner as to prevent their reinsertion into the apparatus.
