The inventive device for extracting a substance (5) from a reservoir (1) comprises an electronic unit (12) with a power supply source (20), an indicator (4), a push element (3) connected to a mechanism for extracting the substance (5) from the reservoir (1), and a controller for the position of the push element (3) linked to the electronic unit. The device also comprises an independent unit (8) which is structurally and electrically co-ordinated with the reservoir (1) and the electronic unit (12). Due to the above-mentioned elements, the device for extracting a substance from the reservoir has some additional functions. Better protection of the contained substance against counterfeiting can be mentioned as a main function, in addition to blockage of the extraction of the substance (5) from said reservoir.</p> |
