Abstract:
Provided is a metered quantity syringe-type dispenser that is capable of multistage pushing. The metered quantity syringe-type dispenser includes a syringe; a plunger configured to be pushed into the syringe; an elastic deforming portion configured to be deformed in response to the pushing of the plunger; and a stopper portion configured to be locked with respect to the syringe and to be released from the locking by restoring force of the elastic deforming portion.
Abstract:
A metering end cap provided to the neck of a flexible container containing a fluid and intended to transfer, at will, an amount of fluid from an upstream space towards a downstream space, this end cap including a chamber in which is disposed a movable valve normally biased towards a rest position and operationally moved towards an end position. The valve isolates the upstream space and the downstream space from each other in its end position and only in this position, and the outlet of the chamber communicates with the upstream space for any position of the valve other that its end position.
Abstract:
An on-demand fluid dispenser to dispense fluid in response to gas generation by a gas cell. The on-demand fluid dispenser includes an expandable gas chamber, a fluid chamber, and an on-demand gas cell. The expandable gas chamber includes a moveable plunger forming a wall of the expandable gas chamber. The moveable plunger also forms a wall of the fluid chamber. The on-demand gas cell is configured to generate the gas on demand. The on-demand gas cell is also configured to direct the gas to the expandable gas chamber to expand the expandable gas chamber. Expansion of the expandable gas chamber moves the moveable plunger to reduce a volume of the fluid chamber and to dispense an amount of fluid from the fluid chamber.

Abstract:
The invention relates to a device (1) for delivering two predetermined doses of a product (3), comprising:—a container (2) for containing said product, said container having a distal end (2d) through which the product is delivered under the distal pressure of a piston,—a pusher (7) movable with respect to said container for causing said piston (4) to move in the distal direction from an initial position, in which none of said product has been expelled to a first position, in which a first dose of said product has been expelled, and to a second position, in which a second dose of said product has been expelled,—a holder body (15) receiving said container and said pusher (7),—biasing means (22) for urging said pusher (7) in the distal direction, from the initial to the first position, and to the second position,—first and second retaining means (9, 11, 19) for maintaining said pusher (7) in said initial position, and in said first position,—first and second actuation means (18) to deactivate said first and second retaining means (9, 11, 19), characterized in that said first and/or second actuation means (18) are at least rotationally displaceable, said rotation causing at least part of the deactivation of said first and/or second retaining means (9, 11, 19).
Abstract:
A one dose at a time, non-pressurised fluid dispensing canister from which the or each dose is dispensed as a result of two surfaces (21, 22) of the canister moving towards one another under the control of the user,—characterised in that the canister incorporates a mechanism which, once a first dose has been dispensed, automatically prevents any further dispensing movement of the said surfaces (21, 22) (in the case where the canister is a one-dosage only canister) or (where the canister is a multiple-dosage-dispensing canister) allows such movement only after the two surfaces (21, 22) have first been moved in a direction or directions other than that which alone caused the first dose to be dispensed.
Abstract:
A dosing apparatus for small doses of a substance, particularly for types of pharmaceutical substances, includes a shoulder and a nozzle for use as a dropper or sprayer on the shoulder. Two outer arms are connected to the shoulder and a container, preferably formed as a hollow cylinder, is located between the two outer arms. An inner arm is formed at an acute angle to each adjacent outer arm with the two outer arms being connected to one another by way of the two inner arms. Two U-shaped tension arches connect the two inner arms to one another, so that the container is centrally positioned between the two U-shaped tension arches, which the two outer arms being able to be pressed together gradually and repeatedly for providing dosing of the desired substance.
Abstract:
The invention relates to a dispenser for the discharge and the atomizing of media, in which a liquid medium is discharged in one charge or a small number of partial charges in one operating stroke of an operating presser or trigger. The dispenser is secured against accidental operation and has a minimum packing or storage volume. Prior to each stroke, the operating presser is returned from an operating end portion to the operating starting position to commence the discharge stroke.
Abstract:
A fluid dispenser device comprising a body (10) defining a dispensing orifice (11), and a reservoir (20) containing one or more doses of fluid, said reservoir (20) having a piston (25) which, at rest, forms a leaktight stopper, said device being characterized in that it further comprises a resilient element (30), such as a spring, that co-operates firstly with said reservoir (20) or with said piston (25), and secondly with a cocking member (40), said cocking member (40) being mounted to be movable manually relative to said body (10) so as to compress said spring (30), and being mounted to be lockable relative to said body (10) in at least one locked position in which said spring (30) is compressed, said device including at least one triggering member (50, 51) adapted to release said spring (30) so as to move said at least one piston (25) relative to said reservoir (20) so as to expel a dose of fluid.
Abstract:
A device for the transnasal or oral administration of drugs or similar media, comprising a finger-like applicator (3) which has a spray nozzle (6) disposed at its free end and includes a cylinder unit (1) for accommodating the medium to be administered. The medium is applied by moving a piston (7) into the cylinder unit (1). A membrane-like seal (4) is located between the cylinder unit and spray nozzle and is slotted to open and form a fluid passage under pressure. The cylinder unit may be built into the applicator or may include a separate cartridge releasably mounted in the applicator. The piston may be activated in steps or in a continuous motion. A second applicator may be attached to the side of the first applicator with the spray nozzles located generally in accordance with spacing of human nose nostrils.
