The container consists of a dome (3.1), a valve with a housing (3.2) and a control rod (3.4) topped by a push button (2). It also comprises a seal (3.5) and a return spring (3.6). The dome and valve housing combine to form a reservoir (3.3) for the product (3.7) to be dispensed, and a propulsion element (3.8). The valve housing and dome are joined together by coupling elements (3.2.1,3.1.4.1), and at least one of them has a skirt (3.1.4) equipped with one set of coupling elements. The two components can be made from a thermoplastic material or from two different, chemically compatible materials which can be joined together by welding. gluing, screwing or clipping.
