  • Patent number: 4246676
    Abstract: An air and liquid tight liquid collecting container includes a cover which may be sealed to the top of the container. The cover includes an inlet port adapted to be connected to a hose which in turn carries a nozzle at the end thereof for picking up liquids. The cover also includes a vacuum port which is adapted to be connected to a standard vacuum cleaner. Associated with the vacuum port is a liquid level sensing device which opens the vacuum port to the atmosphere when the liquid rises to a predetermined level thereby preventing the liquid from entering the vacuum line. A pump, suspended from the cover into the container, pumps the liquid collected in the container to some external desired location.
