Abstract
The invention relates to a device for administering substances at overpressure. The device includes a pressure vessel made of glass and containing a substance to be discharged from the pressure vessel and at least one propellent. The pressure vessel has an opening and an actuable discharge element mounted on the pressure vessel in the opening for releasing the substance from the pressure vessel. A self-supporting housing encloses the pressure vessel and at least a portion of the discharge element to prevent splinters of glass and the discharge element from being propelled away from the device in the event that the pressure vessel bursts. The self-supporting housing has a lower portion made of transparent plastic to facilitate viewing the substance in the pressure vessel.
