Abstract
An apparatus for diluting liquid concentrate materials to liquid use solutions. Liquid concentrates comprise common household cleaning and sanitizing materials such as window cleaners, hard surface cleaners, floor cleaners, sink cleaners, tile cleaners, drain cleaners and openers, glass cleaners, food preparation units, sanitizers, disinfectants, floor finishes and other similar institutional or industrial aqueous or aqueous-alcoholic cleaning solutions. The aspirator system is adapted to receive a container of liquid concentrate in a reservoir. The reservoir contains device to open the liquid concentrate. Additionally the reservoir contains device to support the liquid concentrate during addition of concentrate to the reservoir. When empty, the liquid concentrate bottle can be placed in a receiver for the empty container. The receiver has filling device for the container that can deliver dilute use solution to the container. As should be apparent, the liquid concentrate container and the dilute use solution container are substantially identical.
