<p>The invention relates to an apparatus for diluting liquid concentrate materials to liquid use solutions. An aspirator system (16) is adapted to receive a container (11a) of liquid concentrate in a reservoir (10). The reservoir contains means (13) to open the liquid concentrate. Additionally the reservoir contains means to support the liquid concentrate during addition of concentrate to the reservoir. When empty, the liquid concentrate bottle can be placed in a reservoir for the empty container (11b). The receiver has filling means for the container that can deliver dilute use solution to the container. The liquid concentrate container and the dilute use solution container are substantially identical. The apparatus is controlled using a flow controller (14) that activates liquid diluent causing the liquid diluent to pass through the aspirator drawing concentrate at a fixed dilution ratio. The aspirator can be used in a station with multiple apparatus, each adapted to a particular liquid concentrate and dilute use solution. The typical container for such a station comprises a plastic bottle (11) having a fitment adapted to the receiver opening means. The preferred container for the liquid concentrate contains a fitment comprising a closure for the bottle opening having impressed into the closure a circular indent operatively connected with a thick hinge member. When inserted into the reservoir, the opening means causes the fitment to fail at the circular indent resulting in a clean separation of the circular portion from the closure permitting the contents of the concentrate container to drain into the reservoir.</p> |
