The device comprises a container (30) containing a drug and closed by a piston (31), and a housing (10) intended to be fitted to the container so as to cause a needle (20), which is located in a tubular jacket (13) within the housing (10), to pierce a partition in the piston (31). The interior of the container (30) is thus put into communication with the exterior (30) allowing the supply of the drug due to the penetration of the piston (31) into the container (30) following the penetration of the container (30) into the housing (12). The piston (31) and the inner jacket (13) have complementary mushroom-shaped formations in correspondence with the tip of the needle (20) for coupling with each other. |
