Hand operated sprayer with multiple fluid containers

A spray bottle combination comprising:

• a sprayer mechanism including (a) a sprayer housing, (b) a discharge nozzle, (c) pumping mechanism disposed in the sprayer housing for drawing fluid into the pumping mechanism and discharging fluid to the discharge nozzle, and (d) actuation means for actuating the pumping mechanism, wherein actuation of the pumping mechanism forces fluid from the pumping mechanism out the discharge nozzle;
• a first bottle containing a first fluid;
• a second bottle containing a second fluid;
• a first tubing means for providing fluid communication for the first fluid between the first bottle and the pumping mechanism;
• a second tubing means for providing fluid communication for the second fluid between the second bottle and the pumping mechanism;
• and
• means for controlling relative amounts of first and second fluids entering the pumping mechanism,
• wherein the means for controlling comprises a metering device placed in the first tubing means between the first bottle and the pumping mechanism, the metering device comprising an axially translatable flow restriction device placed in the first tubing means between the first bottle and the pumping mechanism.

A spray bottle combination comprising:

• a sprayer mechanism including (a) a sprayer housing, (b) a discharge nozzle, (c) pumping mechanism including a pump chamber disposed in the sprayer housing for drawing fluid into the pump chamber and discharging fluid therefrom, (d) a fluid passage between the pump chamber and the discharge nozzle, and (e) actuation means for actuating the pumping mechanism, wherein actuation of the pumping mechanism forces fluid from the pump chamber out the discharge nozzle;
• a first bottle containing a first fluid;
• a second bottle containing a second fluid;
• and
• a first means for providing fluid communication for the first fluid between the first bottle and the pump chamber;
• a second means for providing fluid communication for the second fluid between the second bottle and the pump chamber;
• wherein the discharge nozzle comprises (a) a nozzle chamber, (b) a protruding orifice connected to said fluid passage from the pump chamber and extending into the nozzle chamber, and (c) a tip seal positioned in the nozzle chamber and having (i) a plurality of longitudinal ribs forming a fluid passage in the nozzle chamber external to the tip seal and (ii) a closed cavity means in a first end thereof for enclosing and sealing off the protruding orifice, the tip seal being axially translatable during actuation of the pumping mechanism, the tip seal moving to seal off the protruding orifice during drawing of fluid into the pump chamber and moving away form the protruding orifice during discharge of fluid therefrom.

A spray bottle combination comprising:

• a sprayer mechanism including (a) a sprayer housing, (b) a discharge nozzle, (c) a cylinder chamber, (d) piston means disposed in the cylinder chamber axially moveable in a first direction for discharging fluid out the cylinder chamber to the discharge nozzle and in a second direction for drawing fluid into the cylinder chamber, and (e) actuation means for actuating the piston means, wherein actuation of the piston means forces fluid from the cylinder chamber out the discharge nozzle;
• a first bottle containing a first fluid;
• a second bottle containing a second fluid;
• a first tubing means for providing fluid communication for the first fluid between the first bottle and the cylinder chamber;
• a second tubing means for providing fluid communication for the second fluid between the second bottle and the cylinder chamber;
• and
• means for controlling relative amounts of first and second fluids entering the cylinder chamber,
• wherein the piston means comprises first and second internal passages for providing the fluid communication between the respective tubing means and the cylinder chamber.

A spray bottle combination comprising:

• a first bottle containing a first fluid;
• a second bottle containing a second fluid;
• a trigger sprayer comprising a piston and cylinder, a nozzle, a trigger for actuating the piston, and a cylinder chamber within the cylinder wherein actuation of the piston forces fluid form the cylinder chamber out the nozzle;
• a first tubing for providing a first fluid communication path for the first fluid between the first bottle and the cylinder chamber;
• a second tubing for providing a second fluid communication path for the second fluid between the second bottle and the cylinder chamber, said second communication path being separate and independent from said first communication path;
• and
• means for obtaining a desired ratio of first and second fluids entering the cylinder chamber.

A handheld fluid dispensing apparatus comprising:

• a first container containing a first fluid;
• a second container containing a second fluid;
• a fluid dispensing head to which the first container and the second container are connectable, the fluid dispensing head comprising (a) a discharge nozzle, (b) a pump chamber, (c) pumping means for (i) drawing fluid form the first and second containers into the pump chamber at a desired fluid ratio and (ii) discharging fluid out the pump chamber to the discharge nozzle, and (d) actuation means for actuating the pumping means, wherein actuation of the pumping means forces fluid from the pump chamber out through the discharge nozzle;
• a first fluid passage providing fluid communication for the first fluid between the first container and the pump chamber;
• and
• a second fluid passage providing fluid communication for the second fluid between the second container and the pump chamber, said second fluid passage being independent from said first fluid passage.
