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.

Abstract:
An inhaler (1) for dispensing accurate and reproducible doses of powder. The inhaler includes an expulsion channel (2) opening out in an outlet orifice (3), and is characterized by a combination of or: a pre-dosing device (100) having the powder in individual reservoirs (101), each reservoir (101) containing one dose of powder, and; a transfer device (200) for transferring a dose of powder in full into the expulsion channel (2) on each actuation of the inhaler. The inhaler also includes an air flow source (300) having a pump (301) triggerable by the user the air flow source (300) sending a flow of air into the expulsion channel (2) towards the outlet orifice (3) to expel the dose of powder.
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 movable portion of said device that is movable while said device is being actuated, said thin film having anti-friction properties.
Abstract:
A facility for manufacturing, assembling, and filling a fluid dispenser device comprising a fluid reservoir (10) and a dispensing member (20), such as a pump or a valve, said facility being characterized in that it comprises a manufacturing unit for manufacturing a reservoir, a filling unit for filling said reservoir, and a fixing unit for fixing said dispensing member to said reservoir, said units operating continuously in a controlled atmosphere.
Abstract:
This invention relates to a reservoir (10) for a fluid product containing a single dose, the reservoir (10) comprising an air inlet (11) and a product outlet (15), the air inlet (11) comprising a product retention device (12 and/or 13) to keep the product in the reservoir (10) until dispensation of the product, and the product outlet (15) being blocked, preferably in a sealed fashion, by a closing ball (16) which is removed from its blocking position by the flow of air when the product is being dispensed. This invention also relates to the method of filling the reservoir and a dispensing device for the product contained in the reservoir using an air blast (20).
Abstract:
An apparatus for measuring doses of dispensed products includes a first metering ring (20) mounted to rotate 5 around a rotation axis (1), and drive means (10) that drives the first metering ring to rotate around an axis (1). The drive means (10) is actuated each time the dispenser is actuated. The apparatus also has interlocking means (15, 22) that engage the drive means (10) with the first metering ring (20) after the dispenser has been actuated a predetermined number of times. The first metering ring (20) is driven to rotate once it is engaged with the drive means (10). The apparatus only counts the doses of dispensed product after the dispenser has been actuated a predetermined number of times.
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.
