    Abstract: A dispenser device having a dispenser head; an air expeller (20) for generating a flow of air with a piston (21) that slides in an air chamber (22); and a reservoir (30) containing a dose of composition, the reservoir (30) including an air inlet (31) connected to the air expeller (20), and a composition outlet (32) connected to the dispenser outlet (10), the air inlet (31) including a composition retainer member (40), and the composition outlet (32) closed by a closure element (50). The device has an opening system (61, 62) and an indicator (100; 50) that before actuation is in a first state and after actuation passes into a second state. The device includes a pusher element (25) secured to the piston (21). The dispenser head (1) includes a skirt (5) arranged around the air chamber (22), the bottom axial edge of the skirt (5) including a cutout (6).

    Abstract: A nasal powder delivery device having a container containing a dose of powder, a nasal delivery head, and an air discharge system generating a flow of compressed air for delivering a dose of powder into the nostril. An air chamber is arranged in a skirt, and a piston sealingly slides in the air chamber to compress the air. The piston is connected to an actuating member, in which, before actuation, at least one breakable bridge is provided between the skirt and the actuating member, wherein each breakable bridge is formed on the skirt and cooperates with a radial projection formed on the actuating member. Each radial projection has an axial extension greater than that of the respective breakable bridge and forms an inclined axial ramp on either side.

    Abstract: A fluid dispenser device having a dispenser head; an air expeller; and a reservoir containing a single dose of fluid. The reservoir includes a proximal axial end and a distal axial end, and is removably mounted so that after the device has been actuated, the empty reservoir can be removed from the device and replaced by a new full reservoir. The air expeller is adapted to return to its rest position to enable a new actuation with the new full reservoir. The dispenser head includes a proximal perforator tip to perforate the proximal axial end of the reservoir. The device includes a movable perforator member that slides axially around the dispenser head between a loading position and an actuation position and includes a distal perforator tip adapted to perforate the distal axial end of the reservoir when the movable perforator member is moved into its actuation position.

    Abstract: A dispenser device, including an outlet, air expeller including a piston that slides in an air chamber between rest position and dispensing positions, and a reservoir containing a dose composition. The reservoir includes an air inlet connected to the air expeller, and a composition outlet connected to the outlet, the air inlet including a composition retainer member, and the composition outlet being closed by a closure element force fitted in the composition outlet of the reservoir. A mechanical opening system co-operates with the closure element to expel it from its closed position while the device is actuated. The piston, when in its rest position, co-operates in non-airtight manner with the air chamber so that the air chamber communicates with the atmosphere. The piston includes an inner lip co-operating with a cylindrical surface, the cylindrical surface including fluting co-operating in non-airtight manner with the inner lip in the rest position.

    Abstract: A nasal powder dispenser device (100) having a reservoir (110) containing a dose of powder; a nasal dispenser head (120) for inserting into a user's nostril, the nasal dispenser head including a dispenser orifice (121); and an air expeller (130) that, during actuation of the nasal powder dispenser device (100), generates a flow of compressed air so as to dispense a dose of powder into the nostril through the dispenser orifice (121). The air expeller has an air chamber (131) and a piston (132) that slides in airtight manner in the air chamber (131) so as to compress the air contained in the air chamber (131); the nasal powder dispenser device (100) presenting the following properties: a pressure, of the flow of compressed air generated by the air expeller (130), that is higher than 0.7 bar; and a volume, of the air chamber (131), that is greater than 1700 mm3.
