Described is an attachment (1, 1', 1'') with a foam generator (3) for a flexible container (2). Associated with the device (3) are an air bag (6) which is compressed by manual pressure on the container (2), subsequently returning to its original position, and a closable first channel (7) for foam discharge. The attachment (1) is fitted with a first valve (8) which sucks atmospheric air into the air bag (6). For convenience of handling and safety of operation of the attachment (1, 1', 1''), the design includes the following features : The first valve (8) is located outside the first channel (7). There is an air/liquid mixing chamber (36). The air bag (6) is joined to the mixing chamber (36) by a second channel (5) and a second valve (9) actuated by an overpressure acting in the direction of the mixing chamber (36). Associated with the mixing chamber (36) is a third channel (4) for the supply of liquid. |
