Cosmetic unit

Abstract

In a cosmetic unit comprising two applicators, each having a stem, each of the applicators dipping into a respective reservoir, each reservoir having a reservoir neck provided with an external thread on which to screw a respective coupling part, and the two reservoirs being releasably attachable to each other by means of the screwed-on coupling parts, which at the same time serve as a closing cap, via a coupling sleeve by means of a snap-type connection, provision is made for the snap-type connection to comprise a locking bead disposed on the inside of the coupling sleeve in the outer end region of the coupling sleeve.

Claims

1. 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, via a coupling sleeve (14′) by means of a snap-type connection, wherein the snap-type connection comprises a locking bead (16, 16′) disposed on the inside of the coupling sleeve (14, 14′) in the outer end region of the coupling sleeve (14, 14′).

2. A cosmetic unit according to claim 1, wherein the locking bead (16, 16′) is disposed less than 5 mm from the respective front end (17) of the coupling sleeve (14, 14′).

3. A cosmetic unit according to claim 1, wherein the locking bead (16, 16′) in the engaged condition overlaps the respective front end (17) of the coupling part (4, 5).

4. A cosmetic unit according to claim 1, wherein the locking bead (16) cooperates with a corresponding locking groove (18) of the respective coupling part (4, 5).

5. A cosmetic unit according to claim 4, wherein the locking bead (19) has an end region (21) that is beveled in the insertion and snap-in direction (arrow 20).

6. A cosmetic unit according to claim 4, wherein the locking bead (19) has, against the insertion direction (arrow 20), a section (22) extending by approximately 90° against the longitudinal axis of the coupling sleeve (14).

7. A cosmetic unit according to claim 1, wherein the coupling part (4, 5) has a thread whose pitch is between 1.0 and 8 mm.

8. A cosmetic unit according to claim 1, wherein the coupling part (4, 5) has a stem 8 having a diameter between 1.5 and 15.0 mm.
