Abstract
Abstract An inhalator for use with aerosol containers of the type with an extendable and retractable mouthpiece comprises a tubular body intended to receive the aerosol container and having in its upper portion a cutout and a hinge pin for the delivery mouthpiece. The inhalator also includes a tubular cover rotatably applied to the tubular body and provided with a receptacle for receiving a delivery stem of the aerosol container and with a window for allowing extension of the mouthpiece, as well as with a mouthpiece actuating element so that, by rotating the cover until its window is in registry with the cutout in the tubular body, the mouthpiece will be brought to an extended position, and, by rotating the cover until its window is out of registry with the cutout in the tubular body, the mouthpiece will be brought to a retracted position. The delivery mouthpiece is provided on one side with a hinge which mates with the hinge pin which is fixed to the tubular body.
