The dispenser draws a concentrate fluid from a liquid container into an input fluid. There is an elongated channel having an input for the input fluid and dispensing nozzle at an exit end for dispensing the concentrate fluid in a diluted form. A transverse intersecting channel is intermediate the input end and the exit end. An insert is moveable in the transverse intersecting channel, apertures of the moveable insert being alignable with apertures in the transverse intersecting channel and the liquid container. The channels from the liquid container will have a plurality of various sized apertures to provide for the flow of differing amounts of concentrate fluid into the input fluid. By adjusting the moveable insert in the transverse intersecting channel and/or the input fluid flow rate the concentration of concentrate fluid in the input fluid is changed.
A dispenser comprising an elongated channel having a dispensing nozzle at an exit end and an input for an input fluid at an input end, a transverse intersecting channel intermediate the input end and the exit end, the transverse intersecting channel extending through the elongated channel, the transverse intersecting channel containing a movable insert with a plurality of apertures, the elongated channel adjacent the transverse intersecting channel having at least one liquid reservoir aperture for communication to at least one liquid reservoir channel, the at least one liquid reservoir aperture and at least one of the plurality of apertures of the movable insert being alignable, a venturi in at least one of the elongated channel, the transverse intersecting channel and the movable insert to cause a reduced pressure at the at least one aligned liquid reservoir aperture and the at least one of the plurality of apertures of the movable insert whereby a liquid in the liquid reservoir is drawn up into the transverse intersecting channel and into the input fluid by the flow of the input fluid.
A method of dispensing a liquid in a diluted form comprising providing the liquid in a concentrated form in a liquid reservoir, the dispenser having an elongated channel having an input end and an exit end, connecting the liquid reservoir to the elongated channel of the dispenser through at least one liquid reservoir channel, an input fluid flowed through the elongated channel from the input end to the outlet end, a transverse intersecting channel containing a movable insert intersecting the elongated channel intermediate the input end and the exit end, the movable insert having a plurality of apertures, aligning at least one of the plurality of apertures of the movable insert with an aperture of the at least one liquid channel, and flowing input fluid through the elongated channel whereby a given amount of liquid in a concentrated form is drawn from the liquid reservoir and diluted with the input fluid prior to being dispensed from the exit end.
