Abstract

The device comprises: a casing (10) having an open end (10′); a composition support (12) that is movable in the casing between a retracted position and an extended position; and a control piece (16) that is suitable for being moved so as to cause the support to move. The device further comprises first and second magnetic elements (20, 22) that are secured to the support (12) and to the control piece (16) respectively. When the piece is in its first position and when the support is in its retracted position, the magnetic forces between these elements hold the support. When the control piece is moved, the magnetic forces are reduced and enable the support to move towards its extended position.

Claims

1. A packaging device for packaging a composition, in particular a cosmetic composition, the device comprising:

a casing having an open end;

a composition support that is movable in the casing between a retracted position and an extended position that provides access to the composition via said open end; and

a control piece that is suitable for being moved so as to cause the support to move from its retracted position to its extended position;

first and second magnetic elements that are secured to the support and to the control piece respectively, in that, when the control piece is in its first position and when the support is in its retracted position, the magnetic elements generate magnetic forces between them, which magnetic forces are suitable for holding said support in its retracted position, and wherein movement of the control piece, moving said control piece away from its first position, reduces said magnetic forces, so as to enable the support to move towards its extended position.

2. A device according to claim 1, wherein when the control piece is moved away from its first position, the support is caused to move towards its extended position.

3. A device according to claim 1, further comprising a spring that, when the control piece is moved away from its first position, is suitable for causing the support to move towards its extended position.

4. A device according to claim 3, wherein the spring is arranged between the support and the bottom end wall of the casing, which bottom end wall is remote from the open end of said casing.

5. A device according to claim 1, wherein the control piece is secured to an actuator that is arranged on the outside of the casing, and that is suitable for being handled so as to move said control piece.

6. A device according to claim 5, wherein the actuator is a ring that is arranged around the casing.

7. A device according to claim 5, wherein the actuator is configured to be moved in translation so as to move the control piece.

8. A device according to claim 7, wherein the stroke of the actuator is shorter than the stroke of the support.

9. A device according to claim 5, wherein the actuator is configured to be turned so as to move the control piece.

10. A device according to claim 1, wherein when the control piece is in its first position and when the support is in its retracted position, the first and second magnetic elements face each other in a segment of the device that extends transversely to the movement direction of the support.

11. A device according to claim 10, wherein a stroke of the actuator corresponds substantially to a thickness of said segment, measured along the movement direction of the support.

12. A device according to claim 1, wherein the control piece is returned into its first position.

13. A device according to claim 1 wherein one of the two magnetic elements is a magnet, the other of said elements being one of a magnet and a piece made out of a material that is sensitive to the magnetic field generated by the magnet.

14. A device according to claim 1, comprising a cosmetic article having a body that contains a cosmetic composition, and that is received by the support in removable manner.
