Multiple flow rate eductive dispenser

A detachable reservoir for a dispenser that dispenses a chemical fluid drawn from the reservoir eductively diluted into a motive fluid at two flow rates, the dispenser having two conduits for drawing the chemical fluid into respective eductors, the reservoir comprising:

• a bottle having an opening;
• a first pickup tube in fluid communication between a lower portion of the bottle and the opening;
• and
• a second pickup tube in fluid communication between the lower portion of the bottle and the opening.

A dispenser comprising:

• a first eductor;
• a second eductor;
• a reservoir configured to hold a chemical fluid and comprising:
• a bottle having an opening,
• a first pickup tube in fluid communication between a lower portion of the bottle and the opening, and
• a second pickup tube in fluid communication between the lower portion of the bottle and the opening;
• a first conduit communicating between a venturi of the first eductor and the first pickup tube;
• a second conduit communicating between a venturi of the second eductor and the second pickup tube;
• a control configured to selectively direct motive fluid to one of the first and second eductors and to vent the conduit corresponding to the other of the first and second eductors.

A dispenser comprising:

• a means for storing a chemical fluid;
• a means for operatively eductively drawing the chemical fluid from the storing means into a conduit and for discharging the chemical fluid from the conduit for mixing with a motive fluid at a first flow rate;
• a means for sucking the chemical fluid from the conduit and for returning the chemical fluid to the storing means when said eductively drawing means ceases operation;
• a means for operatively eductively drawing the chemical fluid from the storing means into a conduit and for discharging the chemical fluid from the conduit for mixing with a motive fluid at a second flow rate;
• and
• a means for sucking the chemical fluid, mixed at a second flow rate, from the conduit and for returning the chemical fluid to the storing means when said means for operatively eductively drawing the chemical fluid for mixing at a second flow rate ceases operation.

A bottle for a dispenser that dispenses a chemical fluid drawn from the reservoir eductively diluted into a motive fluid at two flow rates, the dispenser having two conduits for drawing the chemical fluid into respective eductors, a first and second pickup tube for insertion into the bottle, and a cartridge that is in fluid communication between the two conduits and the two pickup tubes, the bottle comprising:

• a neck opening sized to sealingly admit the cartridge of the dispenser and including an interference fit to retain the cartridge after insertion;
• a vessel portion configured to receive the two pickup tubes that extend from the cartridge and to store a quantity of the chemical fluid;
• and
• an engagement member for selective gripping by the dispenser.
