A trigger type liquid ejector includes an ejector main body having a vertical supply pipe, an ejection barrel, a trigger mechanism having a main piston and a main cylinder, a reservoir cylinder, a reservoir plunger, a first check valve configured to block communication between a container body and the vertical supply pipe when the main cylinder is pressurized and allow communication when the main cylinder is decompressed, and a second check valve configured to allow communication between an ejection hole and the vertical supply pipe when the main cylinder is pressurized and block communication when the main cylinder is decompressed, and a communication path is provided between the main piston and the main cylinder and is configured to bring the main cylinder in communication with the container body when the main piston is moved to a position deviated rearward from a frontmost position.

A fluid dispensing system is provided. The fluid dispensing system includes a container formed by a first chamber and a second chamber separated by an internal divider. A stopper element extends through each chamber via a first aperture disposed in the internal divider. A second aperture is disposed in a base of the second chamber, wherein the stopper element is used to selectively allow fluid to flow from the first chamber into the second chamber when the stopper element is in a measuring configuration. When the stopper element is in a dispensing configuration, the first aperture between is closed and the second aperture is opened to allow fluid from the second chamber to flow exterior from the container. In this manner, a measured amount of fluid from the container can be dispensed in a single movement without using a secondary measuring receptacle.

The present invention relates to a liquid dispensing device. The device has a main housing, and comprises: a liquid delivery pump, comprising: an inlet; an outlet; a piston, disposed in a cylinder, the piston being movable in a liquid delivery direction between a first position and a second position, and in a liquid priming direction between the second position and the first position; and resilient means for biasing the piston in the liquid priming direction; an operating button, movable between a first position and a second position, and configured to act on the piston to move the piston in the liquid delivery direction; and resilient means for biasing the operating button in the liquid priming direction independently of said piston. In one embodiment, the operating button comprises locking means, configured to engage with the main housing to substantially prevent movement of said operating button in the liquid delivery direction until the operating button and the piston are in their respective first positions. In a further embodiment, the device further comprises a dosing ring configured to limit movement of said operating button in the liquid delivery direction, the dosing ring being adjustably mounted on a support member to enable the volume of liquid dispensed to be adjusted.

A fluid dispenser, comprising: an actuator with a rotatable dial; a valve assembly connected to the actuator, the valve assembly being configured so as to cause fluid to be drawn from a reservoir and released from the dispenser during at least part of the time when the dial is rotated from a start position to one of a plurality of dosage positions and back to the start position, the plurality of dosage positions being at different respective angular positions of the dial; the actuator being configured to provide perceptible feedback at each of the plurality of dosage positions.

A device for dispensing fluid from a fluid container, the device capable of being set to different discrete and repeatable/equal dispensing amounts, depending on the amount of fluid required to be dispensed by the user for various applications and uses. The device may also be set to an off or closed position to prevent accidental dispensing of fluid when not in use. The device is preferably configured to be affixed to the outer surface of a fluid container, which fluid container is preferably a flexible bag or pouch.

A dual dispenser having two pumps (P1, P2) associated with two reservoirs, each pump having a pump body (P10, P20) and an actuator rod (P11, P21) axially movable over an axial stroke; and a dispenser head including a dispenser orifice (O) for dispensing the fluids coming from the actuator rods (P11, P21). The dispenser head has a cap (1) mounted on the actuator rods (P11, P21) and that forms the dispenser orifice (O); a pusher (2) mounted on the cap (1) so as to move it axially downwards and upwards, the pusher (2) also being mounted on the cap (1) so as to turn relative thereto; and an adjustment insert (3) arranged below the cap (1) and that is secured to the pusher (2) to turn with it, the cap (1) coming into abutment against the adjustment insert (3), limiting the axial stroke of the actuator rods (P11, P21).

The invention relates to a dispensing device (1) having a pump device (2), which has an actuating element (5) having an output opening (12), wherein the actuating element (5) is movably arranged relative to a bearing element (6), which is connected to a pump housing (7) in a rotationally fixed manner in the usage position, wherein the actuating element (5) is rotatably arranged relative to the bearing element (6) and the bearing element (6) has at least one protruding bridge (25) having an upper stop edge (24) and a substantially tubular portion (5) of the actuating element (5) has, on the inner surface thereof, distributed over the circumference, at least two stages (22, 22, 22) defining a different displacement path, of which stages, depending on the rotational alignment of the actuating element (5), one stage (22, 22, 22) contacts the stop edge (24) in a lower displacement position.

A method and device for conveying tracking and communicating information concerning a dispensed fluid, said device including a measured dispensing device attached to a flexible collapsible container, said device including a sensor for measuring a physical property relating to the dispensing operation, and a communication device configured to communicate information determined by the sensor to a remote device.

A trigger type liquid ejector includes an ejector main body having a vertical supply pipe, an ejection barrel, a trigger mechanism having a main piston and a main cylinder, a reservoir cylinder, a reservoir plunger, a first check valve configured to block communication between a container body and the vertical supply pipe when the main cylinder is pressurized and allow communication when the main cylinder is decompressed, and a second check valve configured to allow communication between an ejection hole and the vertical supply pipe when the main cylinder is pressurized and block communication when the main cylinder is decompressed, and a communication path is provided between the main piston and the main cylinder and is configured to bring the main cylinder in communication with the container body when the main piston is moved to a position deviated rearward from a frontmost position.
