The invention relates to a device (1) comprising at least two juxtaposed compressed-gas containers (2, 3) which each contain a foamable liquid product (4, 5) containing a liquefied propellant gas. Both compressed-gas containers (2, 3) are provided with a valve (6, 7; 6.1, 7.1) and both of said valves (6, 7; 6.1, 7.1) can be jointly actuated by means of an attachment (8, 8.1). By way of the attachment (8, 8.1) each valve (6, 7; 6.1, 7.1) is provided with a connecting port (9, 10). Said connecting ports (9, 10) discharge into a mixing chamber (11) which is linked to an expansion port (12) whose one end has a foam delivery opening (13). The cross-sections of the connecting ports (9, 10) and the mixing chamber (11) are so small that during the dispensing of a product the products (4, 5) flowing through the connecting ports (9, 10) and the mixing chamber (11) remain in the liquid phase.
