Abstract
The invention relates to a dispensing module for two liquid products, comprising: a first chamber (20) having a first wall, said first chamber having a first opening; a first piston (61) which can be displaced while resting on the wall of the first chamber; a second piston (64) which can be displaced while resting on a wall of the second chamber, and coupling means (62) for coupling both pistons while the product is being dispensed are provided. According to the invention, in order to prevent functional dysfunctions in the event of a distortion of the shape of container and to freely select the shape of the container, said dispensing module comprises a second chamber, the wall of which can be displaced while resting on the second piston, said second chamber comprising a second opening. This is achieved by virtue of the fact that the distortion of the container no longer leads to functional dysfunctions of the dispensing module. Also, the outer shape of the container can be freely selected.
