## Abstract

A fluid dispenser, including a cover element; a blister strip; a blister opening mechanism; a first displacement mechanism having an indexer wheel; a second displacement mechanism pivoting between a non-dispensing position and a dispensing position; a cocking member for urging the second displacement mechanism towards the dispensing position, the cocking member spring-loaded by opening the cover; a blocking mechanism for retaining the second displacement mechanism in the non-dispensing position; a trigger mechanism for releasing the blocking mechanism; a slidable carriage displaceable between a non-indexing position and an indexing position and including an actuator co-operating with the indexer wheel; a connection mechanism activated during inhalation that connects the carriage with the cover, so as to displace said carriage towards its indexing position when the cover element is brought towards its closed position, and so as to displace said carriage towards its non-indexing position when brought towards its open position.

## Claims

### Claim 1

A fluid dispenser device, characterized in that it comprises:
a body provided with a dispenser orifice;
at least one cover element that is movable between a closed position and an open position;
a plurality of individual blisters each containing a dose of fluid, such as a pharmaceutical powder, said blisters being formed on an elongate blister strip;
blister opening means for opening a respective full blister each time said opening means are actuated;
first displacement means for displacing said blister strip so as to bring a full blister to face said opening means before each inhalation, said first displacement means comprising an indexer wheel provided with at least one cavity that receives the blisters;
second displacement means for displacing said blister strip, said second displacement means pivoting between a non-dispensing position and a dispensing position in which a blister co-operates with said opening means, said indexer wheel being mounted to turn on said second displacement means, such that in the dispensing position, said indexer wheel is displaced against said opening means so as to open the blister arranged in said cavity;
a cocking member for urging said second displacement means towards said dispensing position, said cocking member being spring-loaded by compressing a spring by opening said at least one cover element;
blocking means for retaining said second displacement means in the non-dispensing position;
trigger means for releasing said blocking means and for enabling said second displacement means, and thus said indexer wheel, to be displaced towards said dispensing position, said trigger means being actuated by the user inhaling;
a slidable carriage that is displaceable between a non-indexing position and an indexing position, said non-indexing position corresponding to the open position of said at least one cover element, and the indexing position corresponding to said closed position of said at least one cover element, said carriage including an actuator member that co-operates with said indexer wheel so at to turn it when said carriage is displaced from its indexing position towards its non-indexing position;
connection means which, when they are activated, connect said carriage with said at least one cover element, so as to displace said carriage towards its indexing position when said at least one cover element is brought from its open position towards its closed position, and so as to displace said carriage towards its non-indexing position when said at least one cover element is brought from its closed position towards its open position; and
said connection means being activated while said second displacement means are being displaced towards said dispensing position while the user is inhaling, and being deactivated in the absence of any inhalation, such that opening said at least one movable cover and then closing it without inhaling does not cause said indexer wheel to turn.

### Claim 2 (depends on 1)

A device according to claim 1, wherein said connection means comprise a connection finger that is displaceable together with said cocking member.

### Claim 3 (depends on 1)

A device according to claim 1, wherein said indexer wheel includes a set of teeth that co-operate with the actuator member of said carriage when said carriage is displaced from its indexing position towards its non-indexing position.

### Claim 4 (depends on 1)

A device according to claim 1, including two cover elements that are meshed together.
