A fluid dispensing device for dispensing a fluid form medicament formulation having a viscosity of from 10 to 2000 mPa&#xb7;s, is disclosed having a housing and a fluid discharge device. The fluid discharge device is arranged to be actuated by one or more levers, so as to apply a force to the fluid discharge device which is used to move a container forming part of the fluid discharge device, along a longitudinal axis of the fluid discharge device to cause actuation of a pump forming. A pre-load mechanism prevents actuation of the pump until a pre-determined force is applied to each lever of sufficient magnitude to guarantee the production of a well-developed, efficient spray from the fluid dispensing device.

Fluid dispensing device

A fluid dispensing device for dispensing a fluid having a viscosity of from 10 to 2000 mPas at 25&#xb0; C., the dispensing device having at least one finger-operable lever pivotably moveable into the housing transversely with respect to the longitudinal axis of the fluid discharge device, to apply a force to an actuating member connected to the neck of a container, the device having a pre-load to prevent pivoting until a pre-determined force is applied, wherein the actuating member and the lever have surfaces which slidingly interact, wherein the pre-load is formed by one of the surfaces of the actuating member or the lever having a dual-gradient profile.

A nozzle, for use in a fluid dispensing device, having a body defining a fluid flow channel which is shaped to impart acceleration and angular momentum to fluid passing therethrough, an inlet port formed in the body and defining an inlet to the channel, and an outlet port formed in the body and defining an outlet from the channel, wherein the fluid flow channel includes a swirl chamber having a plurality of swirl chamber segments, the swirl chamber being located between the channel inlet and the channel outlet, wherein the body is comprised of a mating assembly of a plurality of like component parts, each of the component parts providing one of the swirl chamber segments; wherein the fluid flow channel includes a plurality of inlets to the swirl chamber for feeding fluid into the swirl chamber and wherein each of the component parts provides one of the swirl chamber inlets; wherein the swirl chamber inlets are positioned to feed fluid into respectively different swirl chamber segments and wherein the swirl chamber segments are fed from one of the swirl chamber inlets provided by another of the component parts; and wherein each swirl chamber inlet is connected to the channel inlet by separate branches of the fluid flow channel.

Nozzle for a nasal inhaler

A fluid dispensing device for dispensing a fluid product having a dispensing outlet from which the fluid product is dispensable, a supply of the fluid product, a dispensing member mounted for movement in a dispensing direction along an axis X-X from a first position to a second position which causes a dose of the fluid product in the supply to be dispensed from the dispensing outlet, and a finger-operable actuator member mounted for movement in an actuating direction which is generally transverse to the axis.

A fluid dispensing device for dispensing a fluid product having a dispensing member mounted for movement along an axis X-X from a first position to a second position which causes a dose of a fluid product to be dispensed, and a finger-operable actuator member movable in an actuating direction generally transverse to the axis to cause at least one cam surface thereof to cam the dispensing member from the first position to the second position. The at least one cam surface has a commitment section, oriented at a first angle to the axis selected such that a minimum actuating force is required to be applied to the actuator member to cause the at least one cam follower surface to ride over the commitment section onto the drive section. The commitment section of the cam surface is arcuate.
