A dosing engine including a framework, fluid drivers, and a flow control device. The framework has an inlet that receives a fluid and an outlet that dispenses the fluid. The fluid drivers are supported by the framework and pump fluid toward the outlet. The flow control device is coupled to the framework and is in fluid communication with the inlet, the outlet, and the fluid drivers. The fluid drivers are cooperatively driven by a motive force from fluid flow through the inlet to dispense fluid via the outlet, and to drive the flow control device to distribute diluent to the diluent drivers in a coordinated manner.

An example apparatus includes a housing including an inlet and an outlet. The example apparatus also includes a rotor defining a bore. The rotor is disposed in the housing. The example apparatus further includes a piston disposed in the bore. A motor is operatively coupled to the rotor to rotate the rotor from a first position to a second position. The bore is to be in fluid communication with the inlet and the outlet when the rotor is in the second position.

A tool, container and method for extracting a liquid; the tool for extracting a liquid comprises: a pressure-changing means, a liquid-reservoir space, a liquid-drawing channel and an outflow channel; the pressure-changing means comprises a cylinder and a piston capable of moving back and forth in the cylinder; the back-and-forth movement of the piston causes positive and negative pressure changes in the cylinder; a start end of the liquid-reservoir space is in communication with the inside of the cylinder; a temporary liquid-storage groove or an opening is provided on a wall of the cylinder at a horizontal position below a port of the start end of the liquid-reservoir space; the volume of the maximum sealing portion of the cylinder is greater than the volume of the liquid-reservoir space; the liquid-drawing channel communicates with the liquid-reservoir space; the outflow channel communicates with a tail end of the liquid-reservoir space.

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.

An apparatus for blending liquids, comprising a main body (100) comprising a seating (106) configured to receive a receptacle (200); a support (140) carried by the main body and having a plurality of slots (142, 142), the support being configured to receive a plurality of cartridges (300, 300), each slot (142, 142) of the plurality of slots being configured to receive a cartridge (300, 300) of the plurality of cartridges; a first actuator configured to move one of the support and the seating relative to the other, thereby enabling positioning of any one slot of the plurality of slots in correspondence of the seating; a second actuator (120) configured to act upon a cartridge (300) placed in the slot (142) currently positioned in correspondence of the seating; and a control unit (150) connected to the first and second actuators. The control unit is configured to receive a data set indicative of a sequence of one or more liquids and, for each of the one or more liquids, an associated quantity of liquid; and for each respective liquid of the sequence of one or more liquids to control the first actuator to move the support or the seating relatively to the other such that the slot holding a respective cartridge of the plurality of cartridges is positioned in correspondence of the seating, the respective cartridge containing the respective liquid of the sequence of one or more liquids; and to control the second actuator to act upon the respective cartridge to cause transfer of a respective quantity of liquid from the respective cartridge into a receptacle positioned in the seating, the respective quantity corresponding to the associated quantity of liquid. A process for blending liquids is also provided.

The invention relates to a device for metering a granular or grainy material in a distributor machine, comprising a housing; an inlet opening which is formed on the housing and through which a granular or grainy material can be introduced in the housing for metering; an outlet opening which is formed on the housing and through which the granular or grainy material can be discharged out of the housing after metering; a metering space which is formed in the housing in such a way that granular or grainy material in the housing can be moved from the inlet opening via the metering space to the outlet opening; a metering wheel which is arranged in the metering space on a drive shaft, and which is configured to meter the granular or grainy material supplied via the inlet opening; a mounting opening which is formed on the housing and via which the metering wheel can be exchangeably mounted in the metering space; and a mounting component which is detachably arranged in the mounting opening in a mounted position, and this in turn is arranged at least partially welded onto the housing, wherein the mounting component has a receiving unit for detachably receiving the metering wheel, in such a way that the metering wheel received on the receiving unit is mounted on the drive shaft when arranging the mounting component in the mounted position, and in such a way that, when detaching the mounting component from the mounted position, the metering wheel is forcibly detached from the drive shaft (6), such that the metering wheel can be removed from the metering space in this way and can be detached from the housing together with the mounting component. A distributor machine is also provided for distributing a granular or grainy material, such as seeds, fertiliser or grit.

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.

The device for packaging and dispensing a product including a storage container (12) provided with at least one variable-volume compartment (22) containing the product, a pressurizing means (30) able to permanently pressurize the product contained in the compartment, and a dispensing head (14) having a mounting base (32) attached to the container.
