Definitions

• Distribution device with safe actuation and recharging of such a device
• the present invention relates to a distribution device with actuation security as well as a recharging of such a device.
• the invention applies more particularly to the field of perfumery where the packaging of the product plays an important aesthetic role. Conditioning can represent a certain value and it is then advantageous to be able to make it profitable. Refills can then be specially provided for this type of packaging.
• the application of the invention in the context of reusable packaging is only a preferential implementation; of course, the actuating safety distribution device of the invention can be used in many other fields such as cosmetics, pharmacy, food, drugstore, etc., without application to reusable packaging.
• a problem at the basis of the present invention is to produce a dispensing device provided with reliable, non-destructive, that is to say reversible, actuation security, and the deactivation of which takes place without requiring a special strength.
• a fluid dispenser device comprising a dispenser member provided with an axially movable actuating head and a reservoir containing the fluid product to be dispensed, said dispenser member being fixed to the reservoir.
• the device further comprises locking means to prevent any axial displacement of the actuating head, and unlocking means to erase the action of said locking means on the actuating head and thus allow the axial movement of said actuating head.
• the unlocking means ensure that the locking means which remain in place on the device are deactivated.
• the blocking means comprise at least one blocking element disposed in the path of axial movement of the actuation head, said blocking element being spaced from the path of axial movement of the actuation head by said unlocking means.
• said at least one locking element is pivotally mounted and comprises a cam surface, said unlocking means engaging said cam surface to pivotally move said locking element out of the axial movement path of the actuation head.
• the blocking means comprise several blocking elements distributed at regular angular spacing all around the actuating head. While disabling the security of the prior art consisting of a strip is simply achieved by tearing it apart or destroying it, in the present invention, the locking elements are moved apart by pivoting without destruction so that the withdrawal of the unlocking means again allows the locking elements to return to their initial position in the path of movement of the head ; this ensures the reversibility of the actuation safety.
• the blocking means are in the form of a blocking ring fixedly mounted on the dispensing member or the reservoir, said blocking ring being provided at its upper end with said pivoting blocking elements, said means unlocking in the form of an unlocking ring attached to the locking ring by biasing the locking elements by pivoting outwardly out of the path of movement of the actuating head.
• the unlocking means are attached to the blocking means with which they thus engage to erase their action.
• the unlocking means act on the locking means independently of the actuation of the actuation head. Unlocking is not carried out by the user's finger as in document US Pat. No. 3,885,717 but by an attached member which does not act on the actuation head.
• the device further comprises a case into which the reservoir is inserted, the unlocking means connecting said case in a removable manner, so that the reservoir equipped with its dispensing member can be introduced and extract from the case as a refill, the connection of the unlocking means on the case putting said means of unlocking in engagement with the blocking means to unlock them.
• the reservoir equipped with its dispensing member constitutes a refill for a case, the upper closing part of which is constituted by the unlocking means which operate both the unlocking of the locking means and the closure from the case.

• the actuation head 2 also includes a pressure surface 20 suitable for applying a finger, for example. A pressure on the surface 20 of the actuation head 2 causes the head and the rod 11 to move axially, as can be seen in FIGS. 1 and 2.
• the depression of the rod 11 has the effect of putting the pump chamber included in the pump body 10 under pressure until the outlet valve of the pump opens and discharges the dose of fluid product through the hollow interior of the actuating rod 11 to the nozzle 21 where the dose of fluid is sprayed.
• the depression of the valve stem 11 has the effect of putting in fluid communication the inside of the tank or a part of it with the outside through the hollow inside of the stem from valve 11 to nozzle 21 where the fluid is sprayed.

• the actuating head can then be moved downwards, which has the effect of emitting fluid by the nozzle 21.
• an unlocking ring 5 to erase the action of the locking elements preserves the reversibility of the locking function of the locking elements 41 by simple withdrawal of the unlocking ring. Indeed, by removing the unlocking ring 5, the cam surface 42 is no longer biased downwards by the bearing surface 51 of the ring 5, which has the effect of pivoting the locking elements 41 again in the axial movement path of the actuating head 2. It is therefore possible thanks to the invention to put the dispensing device back to safety again by simple removal of the unlocking ring 5, which was not possible with the safety devices or guarantees of the prior art which involved destruction of the blocking elements.
