  • Patent number: 7124913
    Abstract: A transportable container for high purity, high cost, liquid chemicals capable of maximizing dispensing of the liquid chemical content of the container at deviations from an upright position, comprising; a top wall, a side wall and a bottom wall, the bottom wall having an internal surface contacting liquid chemical with a concave upward contour having a lowest most point axially central to the container, an inlet, an outlet comprising a diptube through which the liquid chemical can be dispensed from said container with an outlet end adjacent the top surface and an inlet terminal end adjacent the lowest most point, a level sensor assembly having an output end adjacent the top surface and a terminal end adjacent the lowest most point; the diptube and the level sensor assembly being more proximate to one another at their terminal ends than their ends adjacent the top surface.
