Claim:
A cosmetic unit comprising two applicators, each having a stem, each of the applicators dipping into a respective reservoir, each reservoir ( 2 , 3 ) having a reservoir neck ( 12 ) provided with an external thread ( 13 ) on which to screw a respective coupling part ( 4 , 5 ), and the two reservoirs ( 2 , 3 ) being releasably attachable to each other by means of the screwed-on coupling parts, which at the same time serve as a closing cap, by a coupling sleeve ( 14 , 14 ′) formed as a unit by means of a snap-type connection, wherein the snap-type connection includes a pair of first locking beads ( 16 , 16 ′) respectively disposed around the inside circumference of the coupling sleeve ( 14 , 14 ′) at opposite free ends of the coupling sleeve ( 14 , 14 ′) and respectively engaged on the coupling part ( 4 , 5 ) to deter axial movement between the coupling parts ( 4 , 5 ) and the coupling sleeve ( 14 , 14 ′), wherein each coupling parts ( 4 , 5 ) has a second locking bead ( 19 ) disposed around an outside circumference of each of said coupling parts ( 4 , 5 ) and the coupling sleeve ( 14 ) has a pair of locking grooves ( 18 ) disposed around an inside circumference of the coupling sleeve, each of said pair of locking grooves adjoin the respective first locking bead ( 16 ) in the direction away from a respective free end ( 17 ) of the coupling sleeve ( 14 ) wherein the second locking bead ( 19 ) cooperates and engages with the corresponding respective locking groove ( 18 ) of the coupling sleeve ( 14 ).
