Abstract: The invention relates to a screw and a screw assemblage. The screw includes a screw head and a screw shaft which protrudes from an underside of the screw head and has a self-forming or self-cutting thread. The underside of the screw head has a bearing area and at least one annular recess extending around the shaft between the bearing area and the shaft. A coating made of an elastic sealant is attached to the underside of the screw head. The invention further relates to a method for manufacturing an electrically conductive assemblage.

Abstract: A transfer cannula for sterile transfer of fluids to powders or fluids to fluids from a first receptacle into a second receptacle has two tube sections running in the same direction which have different lengths in the longitudinal direction of the tube sections, the longer tube section terminating in an insertion tip. The tube sections are rigidly connected to a coupling wall surrounding the tube sections in a cylindrical manner. The coupling wall has a cutout which extends as far as an end edge of the coupling wall and in which, when viewed from the side, an insertion tip of each tube section is exposed. The coupling wall projects beyond the insertion tip in the direction of the longitudinal extent of the tube sections, and the cut-out widens in a corresponding V-shape at the end edge.

Abstract: An actuator for a metered-dose inhaler is provided. The actuator comprises a body for receiving a canister and a metering valve, and a mouthpiece through which aerosolised canister content can be dispensed.

Abstract: A dispenser for powdery substances contained in a separate package that has a container part with removable container cover, wherein an aspirated air flow is further sucked predominantly through the container part after removal of the container cover from the container part, such that two air flows entering through slits in a lid that can be pivoted around a pivoting axis evacuate the container part from its two ends, and after merging enter a vortex chamber upstream from a mouthpiece. Outside air inlet openings for a third air flow are formed in a housing part covered by the lid in a radial extension to the pivoting axis.
