111 b 111 c made in the internal cylindrical wall 111 of the container 110 is positioned facing a corresponding opening 112 a 112 b 112 c made in the coaxial cylindrical wall 112 positioned outside said wall 111 on the other hand the openings 121 a 121 b 121 c formed in the cylindrical wall 121 of the cover 120 are positioned offset with respect to the openings 122 a 122 b 122 c made in the coaxial cylindrical wall 122 of the cover 120 which wall is situated outside said cylindrical wall 121 with an angular offset of around 60 degrees so that the openings made in one wall are not positioned facing the openings formed in the other successive coaxial wall of the cover thus with such an arrangement when the cover 120 is assembled with the container 110 it is positioned with respect to the latter in such a way that the openings of one pair of cylindrical walls are facing one another so as to put two successive annular chambers into communication the openings of the other pair of cylindrical walls being positioned in an angularly offset manner so that the other two successive annular chambers are isolated from one another furthermore as shown by fig1 to 4 the cover 120 and the container 110 are provided with means of indexed positioning according to the embodiment represented said means of indexed positioning of the cover 120 and of the container 110 comprise on the one hand an opening 123 a extending over an angular sector of the cylindrical wall 123 of the cover 120 which is situated outside the other coaxial cylindrical walls and forms the external peripheral edge of the receptacle and on the other hand a nipple.
