Abstract
The device includes a container (301) and a dispenser head (302) including a central channel (314) closed by a side wall (312) and open on both ends. The side wall (312) includes at least one auxiliary channel (345). The dispenser head (302) includes a reservoir (322) containing a additive (304). A piston (351) is disposed in the reservoir (322) and is arranged to slide in a sealed manner, the piston (351) separating the additive (304) from the substance (303) that serves to propel it outside the cap and which originates in the container. The side wall (312) of the central channel, at its end located on the side of the outlet, includes passages formed by cuts (345), and a dispenser spout (357) is mounted to rotate on the corresponding end of the cap. The spout (357) includes size modifying passages for the free cross section of the passages (345) depending on the angular position of the spout.
