Popis:	To construct one universal valve with a spray or nozzle is not possible. The character of the packed drug, its density, composition, and method of administration require different, precisely defined types of valve-spray systems in each particular case. Thus inhalation preparations require a finely dispersed spray whiie preparations for external application (for the treatment of burns, dermatology, early healing, etc.) require a rough spray. Some drugs used mainly in gynecological and proctological practice must be extruded in the form of a foam and various suspensions in form of a powder.
