ABSTRACT:
A plastic container includes a squeezable bottle providing a lower main liquid reservoir for storing a cleaning solution, an upper dispensing receptacle for measuring and dispensing a measured quantity of liquid, and a transfer duct communicating a lower portion of the main liquid reservoir with an upper portion of the dispensing receptacle for transferring liquid from the main liquid reservoir to the upper dispensing receptacle. After the main liquid reservoir is filled through an opening at the base of the dispensing receptacle, the opening is closed with an insert equipped with a check valve. This same container is adapted to a single flow or double-flow proportioning container by providing a drop tube which opens the check valve and permits liquid to pass from the main reservoir through a check valve housed in a cap assembly, thence through a metering tip to a delivery tube which is in fluid communication with a proportioning device.
