  • Patent number: 8640930
    Abstract: A venting apparatus for a liquid dispensing container adapted to hold a quantity of liquid having a liquid level within the liquid dispensing container. The venting apparatus includes a vent that has an aperture through which gas can exit the liquid dispensing container, a float, a liquid barrier carried by the float, and a flexible tube connecting the vent and the float. The flexible tube establishes fluid communication for gas through the vent and the liquid barrier between an interior space within the liquid dispensing container located above the liquid level and an exterior of the liquid dispensing container.

  • Patent number: 8590756
    Abstract: A consumable supply item for an imaging device holds an initial or refillable volume of pigmented ink. Its housing defines an interior and a fluid exit port. Users orient the housing to deplete the ink in a downward direction. A float on a surface of the ink suspends an inlet opening of a fluid conduit tube underneath the surface. A height of the opening falls downward as the fluid depletes and the float drops. The tube draws a desired concentration of ink and supplies it to the exit port. The concentration is predetermined relative to an overall height of the fluid. The tube height remains proportional to the height of the fluid, increases/decreases proportionally, or other. The design overcomes settling. The design also avoids mechanical stirring and other complex sediment mixing techniques. Embodiments include float/tube arrangements and testing observations, to name a few.

  • Patent number: 8430278
    Abstract: A floating fluid inlet that adjusts to the level of a beverage within a soda keg or similar container. The floating fluid inlet is constructed preferably of stainless steel and food grade plastic tubing. By rotating its inlet port aperture from downward facing when the soda keg is full of a beverage, to upward facing when the soda keg is nearly empty, the floating fluid inlet avoids picking up sediment from the bottom of the soda keg. The principal components are a tube that connects at its one end to the outlet port of a soda keg and at its other end to a pickup tube that is retained within a bracket to which is attached a float. The pickup tube has an aperture disposed in its sidewall for ingress of a beverage.

  • Patent number: 7976796
    Abstract: A centrifuge tube assembly includes an elongate tubular receptacle having a capped upper end. The capped upper end includes a single inlet/outlet port formed therethrough for communication with an interior of the tubular receptacle. A flexible aspiration pipe is communicably engaged with the inlet/outlet port for extending longitudinally through the cylindrical receptacle. A sealing diaphragm is attached to a distal end of the pipe. The diaphragm is longitudinally movable within the tubular receptacle and sealably interengages an interior wall of the receptacle. Biological products are introduced into and aspirated from the receptacle below the diaphragm by the fluid conducting pipe.

  • Patent number: 7331489
    Abstract: A liquid metered dispensing squeeze bottle includes: (a.) a squeezable container having an opening for dispensing liquid therefrom at one end and a bottom at the other end; (b.) a nonflexible trap chamber of a predetermined volume, connected to the opening of the container; (c.) a dip tube, and (d.) a one way valve at the bottom of the dip tube. There is an inlet leg that freely rotates around the bottom of the dip tube and a drive mechanism, such as a counterweight or a float, to assure that the leg extends into an air pocket when the container is tilted for liquid squeeze dispensing.

  • Publication number: 20040108340
    Abstract: A spout affixed to a fluid-dispensing container that allows unobstructed fluid flow until the spout end becomes immersed. The anti-spill and self-venting features are achieved by establishing an airway from the top of the spout and extending into the container in the form of a flexible tube. A float attached to the tube lifts the end to the surface of the fluid within the container. As fluid exits, air enters the container allowing for smooth fluid discharge. When the spout end becomes immersed, fluid is drawn into the vent instead of air. An air vacuum develops that is equal to fluid pressure within the container. Fluid flow is interrupted until the container is returned to an upright position. This allows for fluid to evacuate from the floating vent and back into the contained. The self-venting feature of the spout is then reestablished.
