Abstract

A cosmetic unit comprising two different applicators each with a stem, each of the applicators dipping into a respective reservoir; each reservoir having an externally threaded neck on which to screw a coupling member; and the two reservoirs being releasably attachable to each other via a coupling sleeve by means of the coupling members which are screwed on and which simultaneously serve as a closure cap. The coupling members in the form of screw caps are non-rotarily attachable to the coupling sleeve by an axial serration and axially tightly attachable thereto by a beaded section engaging with a locking groove.

Claims

1. A cosmetic unit (1) comprising two different applicators (6, 7) each with a stem (4, 5), each of the applicators (6, 7) dipping into a respective reservoir;

each reservoir (2, 3) having a neck (8, 9) with an external thread (10, 11) on which to screw a coupling member (12, 13); and

the two reservoirs (2, 3) being releasably attachable to each other via a coupling sleeve (17) by means of the coupling members (12, 13) which are screwed on and which simultaneously serve as a closure cap;

wherein the coupling members (12, 13) in the form of screw caps are non-rotarily attachable to the coupling sleeve (17) by axial projections on the coupling sleeve corresponding with longitudinal flutings on the coupling members and are axially tightly attachable thereto by beaded sections (25) engaging with locking grooves (26) which together form locking members (25, 26).

2. A cosmetic unit according to claim 1, wherein at least one recess 30 is provided on a free edge (29) of the coupling members (12, 13) for facilitating insertion of the coupling members into the coupling sleeve and engagement of the beads of sections (25) in the locking grooves (26).

3. A cosmetic unit according to claim 2, wherein the coupling members (12, 13) are externally provided with the longitudinal flutings (23), which ensures ease of handling upon use as a screw cap as well as producing the non-rotary connection upon cooperation with corresponding the axial projections (22) on an inside of the recess (19, 20) of the coupling sleeve (17).

4. A cosmetic unit according to claim 2, wherein the recess (30) extends axially from the free edge (29) of the coupling members (12) as far as into the vicinity of the locking groove (26).

5. A cosmetic unit according to claim 1, wherein recesses (19, 20) on the coupling sleeve (17) and a section (24) of the coupling members 12, 13 on which the flutings (23) are located are slightly conical.

6. A cosmetic unit according to claim 1, wherein the coupling sleeve (17) has a central dividing wall (18) which, via sections (27) of reduced width, passes into a cylindrical wall (28) of the coupling sleeve (17).
