<p>A pharmaceutical inhaler has a mouthpiece (1) and a cap (2), which are rotatably connected to each other. For providing a certain child-resistancy against disconnection, the mouthpiece is provided with an external circumferential groove (10), whereas the cap is provided with an internal boss (9) for engagement with the groove. There is an axial notch (11) from the groove (10) to the end of the mouthpiece, and 'traps' for the boss in the form of recesses (14) on the groove are provided at either side of the notch.</p> |
