Abstract
A pushbutton for use with a spray device for mixing a primary substance with a predetermined quantity of a secondary substance stored in such a manner as to be sheltered from the air. The pushbutton is constituted by a first piece (2) which is moveable relative to a second piece (1) containing the emission channel (11) of the pushbutton. The first piece (2) includes containers (22) advantageously disposed like rounds in the cylinder of a revolver. Each container (22) contains the desired quantity of the secondary substance and is hermetically closed by a membrane (23). When the user actuates the pushbutton, a suitable resilient piece (3) and suitable connection pieces (15, 25) ensure that the user automatically displaces the first piece (2) in such a manner that the membrane (23) of one of the containers (22) is pierced and the corresponding dose of secondary substance is delivered into the emission channel (11) so as to be sprayed out together with the main substance.
