ABSTRACT:
Container with safety closure, for pharmaceutical preparations or chemicals, having a cylindrical safety sleeve (24; 124) projecting above the end surface of the container neck and disposed externally on the container neck and its projecting portion conformingly receives the circumferential surface of a grip plate (16; 116) of a stopper (14; 114) in the container-closed position. The bottom of the grip plate (16; 116) facing the container mouth rests upon an annularly circumferential radial surface (30; 130) of the safety sleeve (24; 124). The safety sleeve (24; 124) and the container neck (22; 122) are in complementary screw threaded engagement with one another over a limited distance in the opening direction of the stopper (14; 114) and are secured against axial separation from one another. The safety sleeve (24; 124) has at least one projection (36; 136) directed radially inwardly from its inside surface, which is snapped over a first annular bead (32; 132) on the outside surface of the container neck (22; 122), the first annular bead being directed radially outwardly and situated ahead of the projection in the opening direction.
