Abstract

An arrangement for activating an aerosol dispenser having a conveying tube for conveying a liquid; a movable holding member holding the conveying tube; a rotatable base; and a container chamber between the holding member and the base, wherein the arrangement is configured to transmit a loading rotation of the base to a substantially axial loading movement of the holding member towards the base, and wherein the holding member has a locking structure exposed to the container chamber. An aerosol dispenser having the arrangement and a method for activating an aerosol dispenser are also provided.

First claim

The invention claimed is:

1. An arrangement for activating an aerosol dispenser, the arrangement comprising:
a conveying tube for conveying a liquid;
a movable holding member holding the conveying tube;
a rotatable base; and
a container chamber between the holding member and the base;
wherein the arrangement is configured to transmit a loading rotation of the base to an axial loading movement of the holding member towards the base;
wherein the holding member comprises a locking structure exposed to the container chamber; and
wherein the locking structure projects further towards the base than the conveying tube.

2. The arrangement according to claim 1 , wherein the locking structure comprises at least two resilient arms.

3. The arrangement according to claim 1 , wherein the base comprises a rigid structure protruding towards the holding member.

4. The arrangement according to claim 3 , wherein a resilient element extends beyond the rigid structure towards the holding member in an uncompressed state of the resilient element.

5. The arrangement according to claim 1 , wherein the base comprises a resilient element facing the holding member.

6. An aerosol dispenser comprising the arrangement according to claim 1 .

7. The aerosol dispenser according to claim 6 , further comprising a container.

8. The aerosol dispenser according to claim 7 , wherein the base and the locking structure are configured to hold the container when the aerosol dispenser is in an inactivated state.

9. The aerosol dispenser according to claim 7 , wherein the locking structure is configured to attach the container to the holding member by means of a snap-fit.

10. The aerosol dispenser according to claim 7 , wherein the conveying tube is arranged to be brought into liquid communication with the container by means of the axial loading movement of the holding member, such that the aerosol dispenser adopts an activated state.

11. The aerosol dispenser according to claim 10 , wherein the locking structure is arranged to attach the container to the holding member simultaneously as the conveying tube is brought into liquid communication with the container by means of the axial loading movement of the holding member.

12. The aerosol dispenser according to claim 7 , wherein the locking structure is configured to attach the container to the holding member by means of the axial loading movement of the holding member while the base supports a bottom of the container.

13. The aerosol dispenser according to claim 7 , wherein a bottom of the container comprises a stopper arranged to be compressed by the rigid structure due to the axial loading movement of the holding member.

14. A method for activating an aerosol dispenser, the method comprising:
providing a conveying tube for conveying a liquid from a container to a dose chamber of the aerosol dispenser;
providing a rotatable base for supporting a bottom of the container in an inactivated state of the aerosol dispenser, in which inactivated state there is no liquid communication between the container and the conveying tube;
providing a movable holding member holding the conveying tube, the holding member comprising a locking structure configured to attach the container to the holding member by means of an axial loading movement of the holding member towards the base while the base supports the bottom of the container;
providing a container between the base and the holding member;
rotating the base such that the holding member makes the axial loading movement, the locking structure attaches the container to the holding member, the conveying tube is brought into liquid communication with the container, and the aerosol dispenser thereby adopts an activated state.
