Provided is a trigger assembly for an atomizer and an atomizer that includes the trigger assembly. The trigger assembly includes a trigger ring and a delivery tube holder. The trigger assembly has a locked position and an unlocked position. In the locked position, the trigger ring stops axial movement of the delivery tube holder, and in the unlocked position, the delivery tube holder can move in an axial direction relative to the trigger ring. The trigger assembly further includes an actuation member. The actuation member is actuated to drive the delivery tube holder to pivot and drive the trigger ring to move, so that the trigger assembly is switched between the locked position and the unlocked position.

The device is characterized in that said cam surface has, between the first section and the second section (9A, 9B), a third section (9C) of constant height, such that, while said counterpart (1B) slides along said third section (9C), no linear relative motion occurs.

A method for the generation of an aerosol comprises, upon rotation of the rotatable part (1B), a first, charging phase for filling the pumping chamber with liquid, and a second, discharging phase for emitting the atomized liquid from the nozzle (6), and is characterized in that between said two phases, a third, resting phase exists during which, despite further rotation, the volume of the pumping chamber remains constant.

A fluid dispenser device comprising: a reservoir (10) containing one or more doses of fluid; a resilient element (20), such as a spring, for urging said reservoir (10) to move axially between a rest position and at least one actuated position; and blocking means (30; 51, 53, 55) for preventing said reservoir (10) from moving axially; said blocking means being movable manually in a direction that is different from the direction of said axial movement of the reservoir (10) so as to allow said reservoir (10) to move axially; said blocking means comprising a plate (30) provided with an opening (31) comprising a first opening portion (31a) of smaller size, and a second opening portion (31b) of larger size, said first and second opening portions (31a, 31b) being interconnected, said plate (30) being movable radially between a blocking position in which said first opening portion (31a) co-operates with said reservoir (10) so as to block it axially, and a non-blocking position in which said second opening portion (31b) co-operates with said reservoir (10) so as to allow said reservoir (10) to move axially under the effect of said resilient element (20).

A device is designed to put the inhaler into a triggering-ready state by adding energy to a stored energy source of the inhaler. The inhaler can be inserted into the device and/or mechanically coupled to the device in order to put the inhaler into the triggering-ready state.

The disclosure relates to a fluid dispensing device comprising: a housing comprising an orifice and configured to accommodate a portion of a spray delivery device comprising an outlet, a protective cap configured to accommodate the outlet of the spray delivery device and comprising a cap portion, wherein the protective cap is configured for fitting to the housing so that the cap portion covers the orifice, a biasing member transferable between a pre-loaded state and an unloaded state and configured to store energy in the pre-loaded state to produce a discharge of the spray delivery device, a releasable interlock configured to retain the biasing member in the pre-loaded state, a trigger engaged with the interlock and configured to release the interlock when actuated, wherein release of the energy stored in the pre-loaded biasing member is prevented as long as the cap portion covers the orifice.

The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to an inhalation device having improved flow characteristics. A inhalation device for medically active liquids (F) for generation of an aerosol comprises a housing (1), inside this housing (1) a reservoir (2) for storing a liquid (F), a pumping device with a hollow cylinder (9) providing a pumping chamber (3) for the generation of a pressure inside said pumping chamber (3), wherein the pumping chamber is fluidically connected with the reservoir (2) via an inlet check valve (4) which blocks in direction of the reservoir (2), a riser pipe (5) which can be received with at least one reservoir-facing, interior end (5A) in said hollow cylinder (9), and a nozzle (6) which is connected liquid-tight to an exterior end (5B) of the riser pipe (5), wherein the volume of the pumping chamber (3) is changeable by means of relative motion of the cylinder (9) to the riser pipe (5), and is characterised in that the riser pipe (5) is immobile and firmly attached to the housing (1) and to the nozzle (6), whereas the hollow cylinder (9) is moveable relative to the housing (1) and to the nozzle (6).
