  • Patent number: 9327959
    Abstract: A water dispenser includes a raw water container which can be slid into and out of a loading space, while being placed on a slide table. The slide table has a container holder adapted to restrain the peripheral side wall of the raw water container. The minimum height and the shape of the container holder are determined such that when the peripheral side wall of the raw water container is collapsed, the raw water container is never pulled up by the container holder as a result of the peripheral side wall getting caught on the container holder, and such that when the raw water container becomes empty, the raw water container is received within the container holder. This prevents portions of the peripheral side wall from protruding into spaces behind front distal ends of side plates defining the loading space.

    Abstract: Bottled water dispensers are disclosed that include a water bottle receptacle. The water bottle receptacle includes a first and second floating baffle (with a hole disposed in the center portion of the second floating baffle). A raised ring having a triangular cross-sectional shape is located at the bottom portion of the receptacle, which makes contact with the second floating baffle, when the second floating baffle is buoyantly forced upwards into the raised ring to close an aperture through which water is transferred from the water bottle into a cold tank of the water dispenser (during hot water sterilization procedures, when the water level in a cold tank of the dispenser exceeds a threshold level). The second floating baffle is effective to prevent the undesirable heating of water contained within the water bottle during such hot water sterilization procedures.

  • Patent number: 7201178
    Abstract: A method of providing a continuous, sequential, and cyclic, if desired, liquid feed to a processor from a plurality of containers, which comprises feeding the liquid from a first of the containers through a first conduit to a reservoir having a float valve, to keep the level of the liquid in the reservoir high enough to maintain the float valve in an upper floating position that closes the float valve. The first conduit is uncontrolled by the float valve. The float valve controls a second conduit which connects with a second container. As liquid is withdrawn from the reservoir for processing, liquid from the first conduit and container replenishes the reservoir until it is exhausted. Then, the liquid level drops, and the float valve opens the second conduit for replenishing the reservoir with liquid from the second container. A crossover valve may be used so that the float valve controls flow from either container connected to the second conduit.
