A dropper machine for pouring a measured amount of a substance in a plurality of receptacles, including: a reservoir containing the substance to be dropped, cylinder and piston metering devices, a drive unit arranged to simultaneously drive the piston of the metering devices wherein each of the metering devices is associated with a respective actuating device cooperating with the piston of the metering device, the actuator device being operable individually to inhibit the delivery of the substance to be dropped through the nozzle when the drive unit is actuated to cause displacement of the pistons of the metering devices associated therewith between the start position and the end position.

The invention relates to a proportional volumetric doser (10) comprising a motor (20) to which a pump (30) is connected, which pump (30) comprises a tubular sleeve (80) inside which a cylinder (85) is housed in which a small doser piston (62) slides, mechanically connected to an output shaft of the motor (20), wherein an inner surface of the cylinder (85) and the small piston (62) partially define a dosing chamber (48) of an auxiliary fluid to be mixed in the motor (20) in a prefixed amount with the main fluid, where said cylinder (85) has a threaded outer portion that meshes with a threaded portion of a ring nut (70) so that a rotation of the ring nut (70) causes an axial translation of the cylinder (85) and the variation of the volume of the dosing chamber (48), said proportional volumetric doser (30) being characterized in that the sleeve (80) comprises a locking system (100) configured to mechanically lock the cylinder (85) with respect to the tubular sleeve (80) by creating a shape constraint.

A pump system (100) including an overtube adapter (140) and an overtube (150) attached to the overtube adapter (140), the overtube (150) capable of being selectively attached to the overtube adapter (140) to provide different overtube (150) aesthetics for pump systems and fragrance products.

A food ingredient measuring device includes a lower enclosure, an upper enclosure; and a release assembly that passes through the upper enclosure and into the lower enclosure. The release assembly has an activation push-button that extends from the upper enclosure, a pair of connection arms, an inner wall that is at least partially within the lower enclosure and that forms an interstitial space, a seal assembly and a holding cavity. Activation of the activation/release push-button causes the release assembly to retract the seal assembly into the interstitial space to open the holding cavity to enable capture of a cooking ingredient from a bulk container. Another activation causes the release assembly to extend the seal assembly from the interstitial space to close the cavity to capture the cooking ingredient. Another activation causes the seal mechanism to open again to dispense the cooking ingredient.

A handheld solids dispenser. The dispenser includes a housing defining an inlet passage and an outlet passage. A delivery mechanism is supported within the housing and is positioned between the inlet passage and the outlet passage. Actuation of the delivery mechanism causes the delivery mechanism to transport a desired amount of solids material from the inlet passage to the outlet passage. The delivery member may be in the form of a plunger slidably positioned within the housing. The delivery mechanism may be in the form of a screw conveyor driven by a drive motor.

A fluid dispenser having a pump mechanism that dispenses a dose of fluid when a movable pump member of the pump mechanism is moved between an extended position and a retracted position. A pump engagement body engages with the movable pump member for effecting movement of the movable pump member. A first cam surface and a second cam surface are connected to the pump engagement body, at least one of the first cam surface and the second cam surface comprising an adjustable cam surface whose location relative to the pump engagement body is selectively adjustable. A camming body engages with the first cam surface and the second cam surface to effect movement of the pump engagement body, and a dose adjustment mechanism allows the location of the adjustable cam surface relative to the pump engagement body to be selected.

A dispenser includes a dispenser body and a base, wherein the base is attached to the dispenser body and a piston in the base is seated in a fluid passage of the dispenser body to define a dispensing chamber which may be filled by movement of the dispenser body relative to the base and emptied by the return of the dispenser body to the original position relative to the base.

A fluid dispenser having a pump mechanism that dispenses a dose of fluid when a movable pump member of the pump mechanism is moved between a selected extended position and a retracted position. The fluid dispenser includes a dose adjustment mechanism for selecting the selected extended position from at least a high dose extended position and a low dose extended position. An actuator of the fluid dispenser, when activated, effects movement of the movable pump member between the selected extended position and the retracted position to dispense the dose of fluid. A volume of the dose of fluid that is dispensed upon activation of the actuator is higher when the high dose extended position is the selected extended position than when the low dose extended position is the selected extended position.

A variable dose dispenser includes a housing, a sensor, a pump actuator, a drive mechanism and an adjustable drive member. The adjustable drive member is configured to connect to the drive mechanism in a first position and a second position. The adjustable drive member has a first surface with a first drive peg and a second surface with a second drive peg. The first drive peg is offset from a center of the adjustable drive member a first distance that is greater distance than the offset distance of the second drive peg. One of the first drive peg and the second drive peg engages the actuator and the other engage the drive mechanism. The adjustable drive member is secured to the pump actuator in a first position to dispense a first dose size and in a second position to dispense a second dose size.

A drug dispensing-tracking device configured in the form of at least one of a cover, a sleeve, and a cap, and configured to connect with a drug-injection or storage device. The tracking device may comprise at least one or more of: an acoustic sensor, a vibration sensor, an optical sensor, an optical-navigation sensor, and a magnetic sensor, and any combination thereof. At least one sensor may be configured to produce at least one respective signal in response to sensing a vibration, a sound, light, movement, and a magnetic field, respectively, produced by the drug-injection device due to an activity of the drug-injection device.
