Abstract

A safety device for a container having a dispenser rod that is controlled by being depressed may comprise a base configured to be secured to the container while the container is in use; and a blocking member pivotally movable relative to the base, and configured to take up an active position in which it opposes depression of the dispenser rod by an endpiece coupled to the dispenser rod, said endpiece being moved by the user in order to cause product to be dispensed, and an inactive position in which it allows the dispenser rod to be depressed, the blocking member being capable of keeping the active or inactive position into which it is placed by the user once the user ceases to act on the blocking member, the blocking member being connected by a hinge to the base.

Claims

1. A safety device for a container having a dispenser rod that is controlled by being depressed, the safety device comprising:

a base configured to be secured to the container while the container is in use; and

a blocking member pivotally movable relative to the base, and configured to take up an active position in which it opposes depression of the dispenser rod by an endpiece coupled to the dispenser rod, said endpiece being moved by the user in order to cause product to be dispensed, and an inactive position in which it allows the dispenser rod to be depressed, the blocking member being capable of retaining the active or inactive position into which it is placed by the user once the user ceases to act on the blocking member, the blocking member being connected by a hinge to the base.

2. A device according to claim 1, wherein the blocking member is molded as a single piece together with the base.

3. A device according to claim 1, wherein the blocking member defines a laterally-open notch for passing the dispenser rod.

4. A device according to claim 1, wherein the blocking member defines an opening for passing the dispenser rod.

5. A device according to claim 1, wherein the blocking member is configured to snap-fasten on the dispenser rod during placement of the blocking member from the inactive position to the active position.

6. A device according to claim 3, wherein the notch comprises an edge configured to snap-fasten on the dispenser rod during placement of the blocking member from the inactive position to the active position.

7. A device according to claim 6, wherein the notch comprises first and second edge portions substantially matching the shape of the dispenser rod, these edge portions defining an edge suitable for going past the dispenser rod during snap-fastening.

8. A device according to claim 1, wherein the blocking member comprises first and second regions of different heights, the second region underlying an end edge face of the endpiece when the blocking member is in the active position to oppose depression of the endpiece, and only the first region underlying the end edge face of the endpiece when the blocking member is in the inactive position.

9. A device according to claim 1, wherein the blocking member comprises two uprights defining surfaces on which the user can press to cause it to pass from the active position to the inactive position, and vice versa.

10. A device according to claim 9, wherein the uprights are curved at their bases, being concave towards each other and towards the dispenser rod.

11. A device according to claim 1, wherein the blocking member is hinged about a pivot axis substantially parallel to the axis along which the dispenser rod is depressed.

12. A device according to claim 1, wherein the base is configured to snap-fasten on the container.

13. A device according to claim 1, wherein the angular stroke of the blocking member is limited at least in one direction by the blocking member coming into abutment against the base.

14. A device according to claim 13, wherein the angular stroke of the blocking member is limited in a direction opposite the at least one direction by the dispenser rod coming into abutment against the bottom of a notch or an opening in the blocking member.

15. A device according to claim 4, wherein the opening comprises an edge configured to snap-fasten on the dispenser rod during placement of the blocking member from the inactive position to the active position.

16. A device according to claim 15, wherein the opening comprises first and second edge portions substantially matching the shape of the dispenser rod, these edge portions defining an edge suitable for going past the dispenser rod during snap-fastening.

17. A packaging and dispenser device comprising a container and a safety device fastened on the container having a dispenser rod that is controlled by being depressed, the safety device comprising:

a base secured to the container while the container is in use; and

a blocking member pivotally movable relative to the base, and configured to take up an active position in which it opposes depression of the dispenser rod by an endpiece coupled to the dispenser rod, said endpiece being moved by the user in order to cause product to be dispensed, and an inactive position in which it allows the dispenser rod to be depressed, the blocking member being capable of retaining the active or inactive position into which it is placed by the user once the user ceases to act on the blocking member, the blocking member being connected by a hinge to the base.

18. A device according to claim 17, wherein the container is an aerosol can.

19. A device according to claim 17, wherein the container contains a cosmetic.

20. A device according to claim 17, wherein the container contains a household cleaner.

21. A method of making a safety device for a container having a dispenser rod that is controlled by being depressed, the method comprising:

molding as a single piece a base and a blocking member in an active position to form a safety device comprising;

the base, wherein the base is configured to be secured to the container while the container is in use; and

the blocking member, wherein the blocking member is pivotally movable relative to the base, and configured to take up an active position in which it opposes depression of the dispenser rod by an endpiece coupled to the dispenser rod, said endpiece being moved by the user in order to cause product to be dispensed, and an inactive position in which it allows the dispenser rod to be depressed, the blocking member being capable of retaining the active or inactive position into which it is placed by the user once the user ceases to act on the blocking member, the blocking member being connected by a hinge to the base.
