A packaging unit has a cartridge for storing material and pressurized gas operating with it and a dispensing head connected to the cartridge. A sliding piston is positioned in the internal space of the cartridge, the piston divides the internal space into a product chamber and a pressurized gas chamber that have a gas-tight seal between them. A plug is fitted into the pressurized gas chamber end of the cartridge and a valve to the product chamber end, the valve has a valve house, a valve stem, and a disc spring with plate segments. The valve stem has a discharge opening at the end coming out of the cartridge, the end in the product chamber of the cartridge has a conical surface, the plate segments of the disc spring are pushed up against the conical surface of the valve stem, while the disc spring is snapped onto the valve house.

1. In a packaging unit for storing and dispensing of liquids, fluid and ductile materials, having a cartridge for the material to be stored and a pressurized gas operating with it, and a dispensing head connected to the cartridge, comprisinga) a sliding piston ( 4 ) positioned within an internal chamber of said cartridge ( 2 ),b) said piston ( 4 ) divides the internal chamber of the cartridge ( 2 ) into a product chamber ( 3 ) and a pressurized gas chamber ( 5 ), and provides a gas-tight seal between said chambers,c) a plug ( 15 ) fitted into a gas chamber end of the cartridge ( 2 )d) a valve means fitted to a product chamber end of the cartridge ( 2 ), whereine) said valve means has a valve house ( 11 ), a valve stem ( 12 ) being movably arranged in the valve house ( 11 ), and a disc spring ( 14 ) having plate segments, andf) a discharge opening at an end of said valve stem ( 12 ) protruding from the cartridge ( 2 ), and comprisingg) a conical part of said valve stem ( 12 ) being arranged in the product chamber ( 3 ) of the cartridge ( 2 ), whereinh) said plate segments of the disc spring ( 14 ) are pushed against the conical part of said valve stem ( 12 ),i) the disc spring ( 14 ) is snapped onto a valve house ( 11 ), and comprisingj) at least one O-ring arranged between the valve house ( 11 ) and the valve stem ( 12 ),k) a cartridge house ( 6 ) fixed tol) an outer mantle of the valve house ( 11 ). 2. The packaging unit according to claim 1, wherein between the dispensing head ( 1 ) and the cartridge ( 2 ) there are at least three connection element pairs assembled from a tapered profile ( 17 ) and a claw profile ( 18 ); said tapered profiles ( 17 ) and claw profiles ( 18 ) are tensioned towards one another by a rubber ring ( 9 ). 3. The packaging unit according to claim 1, wherein the dispensing head ( 1 ) and the cartridge ( 2 ) are connected to each other with a screw thread. 4. The packaging unit according to claim 1, wherein the dispensing head is coupled with a dispenser house ( 10 ), contains a valve-opening lever ( 8 ) that can be moved on a cross pin ( 7 ), the valve-opening lever ( 8 ) has an internal bearing surface, and this bearing surface touches the shoulder edge of the bearing surface ( 20 ) of the valve stem ( 12 ). 5. The packaging unit according to claim 1, wherein the dispensing head ( 1 ) has a form of a mouth. 6. The packaging unit according to claim 1, wherein the discharge pipe of the valve stem ( 12 ) contains an atomizer insert ( 16 ), that helps material in the liquid state to get out. 7. The packaging unit according to claim 1, wherein the discharge pipe of the valve stem ( 12 ) has a free nozzle that permits the flow of liquid and ductile material.
