A pressure vessel, in particular for use as aerosol bottle or can, has a substantially dimensionally stable, preferably cylindrical first container (11) with a base, side walls and a neck region with an opening. A lid, in which a valve (57) is integrated, closes the opening. A second vessel (71) is arranged in the first vessel (11), wherein a base composition which is to be discharged is accommodated in one of the two vessels and a propellant composition in the form of a nutrient solution (73) and micro-organisms is accommodated in the other vessel. The first vessel (11) is distinguished by the fact that it is produced from a barrier-free thermoplastic. |
