Abstract
A fluid-dispensing device which selectively draws fluid out from at least two containers or fluid chambers, mixes the fluids in a desired concentration or ratio and expels the mixture of fluids out a nozzle. The dispensing device may be equipped with a mechanism for variably controlling the ratio of the fluids being mixed. The containers may be bottles connectable to the fluid-dispensing device and selectively detachable for refilling with fluid or exchanging one of the containers with another container having an alternate fluid. The bottles include mating elements to permit interconnection of the bottles as well as venting and spill prevention mechanisms.
Claims19
A fluid dispensing apparatus for mixing and dispensing a first fluid from a first chamber and a second fluid from a second chamber, comprising:
- a fluid dispensing head, including (a) a discharge outlet, (b) a pump chamber, (c) pumping means for (i) drawing fluid from the first and second chambers into the pump chamber at a desired fluid ratio and (ii) discharging fluid out the pump chamber to the discharge outlet, and (d) actuation means for actuating the pumping means, wherein during actuation of the pumping means, volume of the pump chamber is reduced forcing fluid from the pump chamber out through the discharge outlet such that substantially all the fluid in the pump chamber is discharged out the discharge outlet;
- a first fluid passage providing fluid communication for the first fluid from the first chamber to the pump chamber;
- and
- a second fluid passage providing fluid communication for the second fluid from the second chamber to the pump chamber, the second fluid passage being independent from the first fluid passage.
A fluid dispensing apparatus for mixing and dispensing a first fluid from a first chamber and a second fluid from a second chamber, comprising:
- a fluid dispensing head, including (a) a fluid outlet, (b) a pump chamber, (c) pumping means for (i) drawing fluid from the first and second chambers into the pump chamber at a desired fluid ratio and (ii) discharging fluid out the pump chamber to the fluid outlet, and (d) actuation means for actuating the pumping means, wherein actuation of the pumping means forces fluid from the pump chamber out through the fluid outlet;
- a first fluid passage providing fluid communication for the first fluid from the first chamber to the pump chamber;
- a second fluid passage providing fluid communication for the second fluid from the second chamber to the pump chamber, the second fluid passage being independent from the first fluid passage;
- and
- means for controlling the desired fluid ratio of first and second fluids entering the pump chamber, the means for controlling comprising a metering device associated with the first fluid passage, wherein the metering device comprises an axially translatable flow restriction device.
A fluid dispensing apparatus for mixing and dispensing a first fluid from a first chamber and a second fluid from a second chamber, comprising:
- a fluid dispensing head, including (a) a fluid outlet, (b) a pump chamber, (c) pumping means for (i) drawing fluid from the first and second chambers into the pump chamber at a desired fluid ratio and (ii) discharging fluid out the pump chamber to the fluid outlet, and (d) actuation means for actuating the pumping means, wherein actuation of the pumping means forces fluid from the pump chamber out through the fluid outlet;
- a first fluid passage providing fluid communication for the first fluid from the first chamber to the pump chamber;
- and
- a second fluid passage providing fluid communication for the second fluid from the second chamber to the pump chamber, the second fluid passage being independent from the first fluid passage,
- wherein the pumping means comprises a piston and cylinder combination, the piston including first and second internal passages for providing the fluid communication between the respective fluid passage and the pump chamber.
A fluid dispensing apparatus for mixing and dispensing a first fluid from a first chamber and a second fluid from a second chamber, comprising:
- a fluid dispensing head, including (a) a fluid outlet, (b) a pump chamber, (c) pumping means for (i) drawing fluid from the first and second chambers into the pump chamber at a desired fluid ratio and (ii) discharging fluid out the pump chamber to the fluid outlet, and (d) actuation means for actuating the pumping means, wherein actuation of the pumping means forces fluid from the pump chamber out through the fluid outlet;
- a first fluid passage providing fluid communication for the first fluid from the first chamber to the pump chamber;
- a second fluid passage providing fluid communication for the second fluid from the second chamber to the pump chamber, the second fluid passage being independent from the first fluid passage;
- and
- externally operable ratio adjustment means for selectively varying relative amounts of first and second fluids entering the pump chamber.
A fluid dispensing apparatus for mixing and dispensing a first fluid from a first chamber and a second fluid from a second chamber, comprising:
- a fluid dispensing head, including (a) a fluid outlet, (b) a pump chamber, (c) pumping means for (i) drawing fluid from the first and second chambers into the pump chamber at a desired fluid ratio and (ii) discharging fluid out the pump chamber to the fluid outlet, and (d) actuation means for actuating the pumping means, wherein actuation of the pumping means forces fluid from the pump chamber out through the fluid outlet;
- a first fluid passage providing fluid communication for the first fluid from the first chamber to the pump chamber;
- and
- a second fluid passage providing fluid communication for the second fluid from the second chamber to the pump chamber, the second fluid passage being independent from the first fluid passage,
- wherein the pump chamber is positioned immediately adjacent the fluid outlet for minimizing the amount of mixed fluid remaining in the fluid dispensing head after actuation of the pumping means.
A fluid dispensing apparatus, comprising:
- a first chamber adapted to contain a first fluid;
- a second chamber adapted to contain a second fluid;
- a fluid dispensing head, including (a) a discharge outlet, (b) a pump chamber, (c) pumping mechanism for (i) drawing fluid from the first and second chambers into the pump chamber at a desired fluid ratio and (ii) discharging fluid out the pump chamber to the discharge outlet, and (d) actuator for actuating the pumping mechanism, wherein during actuation of the pumping mechanism, volume of the pump chamber is reduced forcing fluid from the pump chamber out through the discharge outlet such that essentially all the fluid in the pump chamber is discharged out the discharge outlet;
- a first fluid passage providing fluid communication for the first fluid from the first chamber to the pump chamber;
- and
- a second fluid passage providing fluid communication for the second fluid from the second chamber to the pump chamber, the second fluid passage being independent from the first fluid passage.
