A manually operated pump including: an inlet one-way valve; a pump chamber downstream of and in fluid communication with the inlet one-way valve; a piston interior to the pump chamber and slideably engaged with the pump chamber; an actuator engaged with the piston or the pump chamber; a block thermoplastic elastomeric spring engaged with the actuator to move the actuator as the block thermoplastic elastomeric spring relaxes; and an optional outlet one-way valve downstream of and in fluid communication with the pump chamber.

A fluid dispenser device including an outlet, a pocket having an interior volume for containing a fluid, the interior volume being delimited at least in part by a movable wall, a reservoir arranged to contain the fluid, a pocket cap, a cavity, a reservoir orifice joining the reservoir and the cavity; wherein the pocket cap is arranged to be mounted by insertion in the cavity of the device so as to be mounted by extending: by passing through the pocket at least partially while passing through the movable wall orby going along the pocket at least partially, the device comprising an inlet orifice arranged to insert the pocket cap into the device from the outside of the device and opening into the cavity.

The invention relates to a dosing device comprises a fluid-side module (12,12) and a dry module (13), the fluid-side module (12,12) comprises a chamber (14) and a magnetic piston (16) which is drivingly moved into the chamber (14) by a magnetic drive, the piston is penetrated by a channel provided with a seal (20,56). The magnetic drive for the magnetic piston (16) is arranged in the dry module (13).

The invention relates to a system having a dosing dispenser for dispensing pasty or viscous material with a housing, a cartridge displaceably accommodated therein and a walking piston accommodated in the cartridge that forms a unit ready for assembly with a shutter button to be arranged at a cartridge end.

Fluid delivery device for discharging a fluid, having: a housing; piston pump; biasing mechanism; and trigger mechanism. The housing has a basal end and a discharge end with outlet for discharging the fluid. The piston pump has a casing defining a pump chamber for storage of fluid, a piston slidably movable relative to the pump chamber, a piston plunger, and a delivery channel. The trigger mechanism is movable from a cocked configuration wherein the trigger mechanism prevents transfer of a biasing force of the biasing mechanism to the casing to a triggered configuration with the trigger mechanism enabling transfer of the biasing force to the casing to cause movement of the casing towards the housing outlet to discharge fluid from the pump chamber, along the delivery channel and out of the outlet of the housing. The biasing mechanism has one or more flexible catch members and a manually operable trigger.

A dispenser includes a housing and a discharge opening provided at the distal end of the housing. The dispenser includes a liquid reservoir and a control device having a pump or a switching valve, which control device is connected by a first line to the liquid reservoir and by a second line to the discharge opening, and via which control device liquid is conducted from the liquid reservoir to the discharge opening. The dispenser includes a push button which provided laterally in a cutout of a circumferential face of the housing and connected to the control device that pressing the push button actuates the control device so that liquid is conducted to the discharge opening. Measures for securing the dispenser include a rotatable sleeve over the push button, a secured cap, a securing arrangement on the push button, an interaction of the push button with an opposite side of the dispenser, and a receiving sleeve for the dispenser.

A nebulizing device (100) is provided, including: a hollow housing (101), including a cavity (110). where the cavity (110) includes a liquid channel (111) located inside the cavity and a nebulizing spray nozzle (103) located at a distal end of the liquid channel (111) with a plurality of fluid outlets; and an injector (102), at least partially accommodated in the cavity (110). The injector (102) includes: a reservoir (120), configured to accommodate liquid; a liquid conveying pipe (121) including a liquid inlet (122) and a liquid outlet (123), where the liquid inlet (122) is located in the reservoir (120), the liquid outlet (123) is located in the liquid channel (111), the liquid outlet and the nebulizing spray nozzle (103) jointly define a liquid chamber (124), and the liquid conveying pipe (121) is configured to convey the liquid in the reservoir (120) into the liquid chamber (124); and an injector proximal end (102), which is coupled to the liquid conveying pipe (121) and configured to receive a pushing force, so that the liquid conveying pipe (121) is movable in the cavity (110) from a proximal position to a distal position to form a predetermined nebulizing pressure at the nebulizing spray nozzle (103), and the liquid can flow out through the nebulizing spray nozzle (103) and converge to generate a plume spray with a predetermined initial speed, where at least 50% of droplets in the plume spray have an average particle size ranging from 1 um to 10 um.

A product dispenser is provided that includes a container within a shell, and a pump and insert for dispensing the product. A spring biases the container and pump away from the tip of the shell. The bottom of the container is pushed up relative to the shell to activate the pump, thereby dispensing the product.

An exhaust valve assembly for a bottle attachment apparatus for handling liquids has a valve housing which forms a valve chamber having an inlet and an outlet, an exhaust valve body disposed on the inlet in the valve chamber, and a safety valve body disposed on the outlet in the valve chamber. The exhaust valve body is biased toward an exhaust valve seat, counter to the flow direction of the liquid and the safety valve body is biased toward a safety valve seat in the flow direction of the liquid. The safety valve seat is integrally molded on the valve housing.
