Abstract:
A device is provided for emptying a metering chamber of a powder dispenser. The dispenser includes an expulsion channel passing through the metering chamber and a device for delivering an air flow which is intended to pass along the expulsion channel to empty the metering chamber when the dispenser is actuated. A flow device is adapted to configure the air flow in such a manner that it empties the metering chamber completely. The flow device is disposed in the expulsion channel upstream from the metering chamber in the flow direction of the air flow.
Abstract:
A device for counting doses of substance issued by a dispenser for fluids or powders, the device being characterized in that it comprises a first count wheel (10, 110) and a second count wheel (20, 120), both count wheels being mounted to rotate about a fixed axis of rotation (3, 103), the first count wheel (10, 110) comprising a set of teeth (11, 111) extending circumferentially about the fixed axis of rotation (3, 103) and co-operating with a drive member (30, 130) for rotating the first count wheel about the fixed axis of rotation on each use of the dispenser, the first count wheel (10, 110) further including a drive tongue (14, 114) that is movable between a rest position in which it does not co-operate with the second count wheel (20, 120), and a drive position in which it does co-operate with the second count wheel (20, 120) to cause it to rotate about the fixed axis of rotation, said drive tongue (14, 114) being forced into its drive position by cam (8, 108).
Abstract:
A treatment method for treating the surface of a fluid dispenser device, said method being characterized in that it comprises a step of using chemical grafting to form a thin film on at least one support surface of at least one portion of said device that is in contact with the fluid while said device is being actuated, said thin film having non-stick properties relative to said fluid.
Abstract:
A treatment method for treating the surface of a fluid dispenser device, said method comprising the step of using chemical grafting to form a thin film on at least one support surface of at least one portion of said device that is in contact with said fluid, said thin film having bactericidal and/or bacteriostatic properties.
Abstract:
An electronic display device (20) including a display member (21), said device being characterized in that said display member (21) is permanent so that no energy is required to keep the display unchanged, said display device (20) operating without a battery, the energy required to change the display being created by interaction between two elements, such as by friction or by an impact, thereby creating an electric pulse, said pulse being processed by an electronic circuit (25) before being applied to the display member (21) in order to change its display.
Abstract:
A device for projecting measured quantities of a fluid substance by a puff of compressed air, said device comprising: a body (1) having an ejection channel (4); an actuator member (2) displaceable relative to the body (1) between a rest position and an actuated position; a resilient return member (19) urging the actuator member (2) towards its rest position; a supply (3) of said substance; a feed (5, 6) adapted to move a measured quantity of said substance from the supply (3) into the ejection channel (4); and an air pump (7) comprising a pump chamber (8) having an inlet valve (10, 11) in communication with the atmosphere; the device being characterized in that the outlet valve is constituted by a valve piston (12) constrained to be displaced with the actuator member (2) and sliding in sealed manner in a valve cylinder (13) having a top end (13a), said cylinder having a lateral outlet orifice (14) which communicates with the ejection channel (4), said valve cylinder having its top end (13a) in communication with the pump chamber (8), said lateral outlet orifice being positioned sufficiently far from said top end (13a) of the valve cylinder for the valve piston (12) to isolate the lateral outlet orifice (14) from the pump chamber so long as the actuator member (2) is not in the immediate vicinity of its actuated position.
Abstract:
A powder inhaler comprising a box (1) in which a suction channel (84) is formed enabling a user to inhale a powder, the inhaler being characterized in that it includes a pusher (2) associated with a return spring (83), actuation thereof enabling a dose of powder to be brought into a position enabling it to be sucked into the suction channel (84), and in that the box (1) includes a locking mechanism enabling the pusher (2) to be locked after it has been actuated, and enabling it to be unlocked when the user sucks up the dose of powder in the channel (84).
Abstract:
A treatment method for treating an elastomer surface of a fluid dispenser device, the method including the step of using chemical grafting to form a thin film on at least one support surface of at least one elastomer surface of the dispenser device, the thin film avoiding the elastomer surfaces sticking during the manufacturing and assembly stages.
Abstract:
A fluid dispenser device comprising: at least one predosed reservoir (10) that is hermetically sealed and that contains a single dose of powder; an expulsion channel (20) that is terminated by a mouthpiece; and a reservoir opening system (30), each reservoir (10) including a closure layer (12) that is suitable for being pierced and/or torn by said opening system (30) so as to enable the powder that is contained in said reservoir (10) to be expelled through said expulsion channel (20), said reservoir opening system (30) comprising at least two piercer elements (31) that are actuated so as to create at least two distinct openings (25, 26) in said closure layer (12), forming at least one inlet passage (25) for the flow of gas, in particular air, and at least one outlet passage (26) for the powder entrained by said flow of gas, and said device including an inhalation trigger system (50) that creates a flow of gas in said expulsion channel (20) only when a user inhales at or above a predetermined inhalation threshold.
