  • Patent number: 9753464
    Abstract: A beverage system includes a pump that draws a set amount of a flavored concentrate into a mixing chamber through a conduit for mixing with water to form a beverage. A sensor detects when the amount of the flavored concentrate in the conduit is low or the amount of the flavored concentrate in a concentrate container is low or out. The sensor includes two wings each including a recessed surface that together define a circular space. A portion of the conduit is received in the circular space. Each of the wings includes an ultrasonic portion that emits ultrasonic waves that are non-intrusive. When the amount of flavored concentrate in the conduit is low, air bubbles are generated in the flow of the flavored concentrate as it flows along the conduit and/or a vacuum is created in the conduit to draw the conduit away from the recessed surfaces. The ultrasonic waves detect either of these two features, indicating that the amount of the flavored concentrate is low.

    Abstract: A dispenser for dispensing a diluted form of a concentrated product includes: a supply of concentrated product; a dilution chamber; an actuation assembly and a product pump mechanism having a water staging chamber. The actuation assembly receives water under pressure from a pressurized water supply. In a staging state, water from the pressurized water supply is fed to the water staging chamber, increasing the volume thereof and causing the actuating of the pump mechanism thereby driving a dose of product into the dilution chamber. In a return state, (a) water within the water staging chamber exits the water staging chamber, (b) water is advanced to the dilution chamber and mixes with the dose of product to create diluted product, and (c) a dose of concentrated product is drawn from the supply of concentrated product into the product pump mechanism.

    Abstract: A metering device meters and dispenses of a known volume of a liquid product. The metering device includes a receptacle and a moveable slug sized to fit within the receptacle, leaving a remaining volume within the receptacle equivalent to a desired amount of a liquid product to be dispensed. Application of a vacuum at the outlet end draws the known volume of liquid product out of the receptacle and causes the moveable slug to move from a first position at the inlet end of the receptacle to a second position at the outlet end of the receptacle. At the same time, additional liquid product is drawn in via the inlet aperture. When the vacuum is removed, the slug returns through the additionally drawn-in liquid product back to the first position.

The fluid dispenser can be portable and/or disposable, and in some embodiments is adapted for installation on an upper rim of a reservoir wall. Also, the fluid dispenser can be provided with a baffle limiting the velocity and impact of incoming diluent to the wheel driving the pump, thereby improving dosing accuracy of the dispenser in some embodiments.

  • Publication number: 20090294469
    Abstract: Mass-based dispensing of a powder product includes a system that dispenses a powder product containing an active ingredient from a product container. The system initiates a dispense cycle at a first, higher dispense rate. The system continuously determines, as the powder product is dispensed, the amount or weight of the powder product that has been dispensed. Once a transition criteria has been satisfied, the system adjusts the dispense rate to a second, lower dispense rate. The system dispenses the powder product at the second, lower dispense rate until a requested amount of the powder product has been dispensed.

  • Patent number: 7459128
    Abstract: A microfluidic dispensing tap, such as for use in screening assays, includes a dispensing tube translatable within a sealed reservoir housing. The tube has an outer surface and defines an inner cavity open at a lower end of the tube, and a metering aperture extending through a side wall of the tube between the inner cavity and the outer surface to define a known volume. The tube is movable against a seal at a lower end of the reservoir housing between a first position, in which the metering aperture is disposed below the seal, and a second position, in which the metering aperture is disposed above the seal and exposed to the reservoir for entraining a discrete dose of a sample liquid within the aperture. An injector is configured to inject a known quantity of a diluent into the inner cavity of the tube and into fluidic contact with the dose of sample liquid in the aperture, such that the dose of sample liquid diffuses into the diluent to form a discrete mixture for dispensing from an open end of the tube.

  • Publication number: 20080272143
    Abstract: A beverage system includes a pump that draws a set mount of a flavored concentrate into a mixing chamber through a conduit for mixing with water to form a beverage. A sensor detects when the amount of the flavored concentrate in the conduit or in the container is low or out. The sensor includes two wings each including a recessed surface that together defines a circular space. A portion of the conduit is received in the circular space. Each of the wings includes an ultrasonic portion that emits ultrasonic waves that are non-intrusive. When the amount of flavored concentrate in the conduit is low, air bubbles are generated in the flow along the conduit and/or a vacuum is created in the conduit to draw the conduit away from the recessed surface. The ultrasonic waves detect either of these two features, indicating that the amount of the flavored concentrate is low.

    Abstract: A liquid dispensing device for the selective oral administration of a liquid medicine simultaneously with a liquid beverage. The device includes a cup for holding a beverage and a lid sealably connectable onto the open upper end of the cup. The cup includes an elongated cylindrical medicine cavity having an open lower end and a narrowing upper discharge tip. The medicine cavity is formed into the outer perimeter surface of the cup for concealment. A medicine plunger is sealingly movable within the medicine cavity for discharging liquid medicine from the discharge tip. The lid has a tapered upwardly extending drinking spout with preferably two spaced ports and a second port positioned between the first ports whereby liquid beverage in the cup may be dispensed from the first ports by gravity feed and liquid medicine in said medicine cavity may be independently selectively dispensed from the second port by movement of the medicine plunger.

  • Patent number: 6752323
    Abstract: A hot melt high temperature material application system with application device pressure monitoring and heated recirculating manifold uses high temperature pressure transducers with each application device such as spray guns to monitor hot melt material application. A material supply line fitting has a calibrated orifice at the interface with a device manifold associated with each application device. In another embodiment, the calibrated orifice is located in a fluid passageway of the device manifold. The calibrated orifice corresponds in size to the opening of a nozzle of the application device. Heated recirculating manifolds are combined with hot melt material supply systems to provide uniform pressure to multiple application devices, and to recirculate material back through the supply system. Each recirculating manifold includes a heater, pressure regulator, and a recirculation path. The manifolds may be directly or remotely connected to one or more hot melt material supply systems.
