Abstract: A beverage bottle for storing and dispensing water and impure sports beverages having a container and a dispensing opening on a top wall movable between an open position and a closed position and a unitary valve disposed within the container bottom wall having a vertically sinuous contour, and laterally opposed, laterally actuating, compliant slit faces and a substantially rigid annular flat surface. As the vertically sinuous contour is flattened upon the annular flat surface, the slit faces are laterally urged together establishing a preloaded seal, for leak resistant valve operation, and reduced restriction dispensing of water and impure sports beverages.

Abstract: A device for heating or cooling beverage containers, such as hot drinks or cold drinks, in a vehicle. A beverage container, such as a can of pop, is inserted into the device and its insertion activates the selected function, either heating or cooling. The beverage container may be inserted with one hand and removed with one hand, allowing it to be used safely by a driver. Heat transfer members within the device conform to the beverage container, and automatically adjust for different sizes of beverage container circumferences. The heat transfer members also automatically adjust themselves to accommodate varying top-to-bottom taper of beverage containers. A thermally conductive and pliable interface layer between the beverage container and the heat transfer members insures efficient heat transfer contact, and efficient heat transfer.
