A method for manufacturing a pressurized two-chambered container in the form of an aerosol can, in which a housing is provided with an opening that can be sealed tightly by a spray or aerosol valve. A product chamber and a propellant chamber are formed separately fluid-tight from each other by a flexible diaphragm in the housing. The product chamber can be charged with a product which can be release through said valve. The propellant chamber can be charged, on the other hand, with a compressed propellant. The product chamber communicates with the product-release opening. At least one end of a blank is left open to constitute subsequently the housing. The diaphragm is inserted into the blank through the open end, and the blank then is formed into the housing. An edge of the open end of the blank is reformed to narrow it into an integral mouthpiece that accommodates the product-release opening.
