The present invention relates to fluid dispensing devices for use in dispensing different liquids (e.g., bleach and bleach activator) from a bottle having first and second compartments. To minimize the presence of mixed composition residually present within the fluid dispensing device, it may be helpful to delay mixing. Separate dip tubes may be provided to pull liquid from the separate compartments, each with its own separate pump. Each pump may deliver the separate compositions to a spray nozzle of the device through separate delivery tubes (e.g., from the pumps to the nozzle). In other embodiments, a single delivery tube, and/or a single pump may be provided, e.g., where the volume of mixed composition that may be present in such pump and/or delivery tube may be sufficiently small so as to still provide overall desired efficacy characteristics. Dual delivery tube configurations may eliminate any need to prime the device by spraying out old, residual mixed composition.

The fluid dispensing device of claim 1, wherein the trigger requires less than 15 lbs of force for actuation. 3. The fluid dispensing device of claim 1, wherein the first dip tube and the second dip tube are aligned, one behind the other relative to the nozzle of the fluid dispensing device, and the first delivery tube and the second delivery tube are vertically aligned with one another. 4. The fluid dispensing device of claim 1, wherein the first pump and the second pump deliver substantially the same volume of the first and second fluids, respectively, to the nozzle substantially simultaneously to allow the dispensing device to aspirate an approximately 1:1 mixture of the first and second fluids. 5. A fluid dispensing device comprising: (a) a bottle having a front side, a back side, a bottom, a first neck, a second neck, and a bottle snap coupling below a top of the first and second necks;(b) the bottle comprising a first compartment adjacent a front side of the bottle, and a second compartment adjacent a back side of the bottle;(c) a dispensing head comprising a frame, a trigger, a first pump and a second pump, wherein the first pump is closer to a dispensing end of the device and a second pump is closer to the back side of the bottle so that the first pump and the second pump are in front to back alignment;(d) a transmission member which translates actuation of the trigger to substantially simultaneous reciprocation of both the first and second pumps;(e) a first dip tube fluidly connected to the first pump and an interior volume of the first compartment housing a first fluid;(f) a second dip tube fluidly connected to the second pump and an interior volume of the second compartment housing a second fluid; and(g) a nozzle which fluidly communicates with the first and second pumps by way of a first delivery tube and a second delivery tube, respectively; and wherein the first dip tube and the second dip tube are aligned, one behind the other relative to the nozzle of the fluid dispensing device, and the first delivery tube and the second delivery tube having a void space between and are vertically aligned one above the other in a same vertical plane. 6. The fluid dispensing device of claim 5, wherein the trigger requires less than about 15 lbs of force for actuation. 7. The fluid dispensing device of claim 5, wherein the trigger includes a top portion which contacts a reinforcing flange on the frame which prevents reverse actuation motion of the trigger. 8. The fluid dispensing device of claim 5, wherein the trigger includes a bottom portion which is used as a single point of contact to support at least about 12 lbs of force. 9. The fluid dispensing device of claim 5, wherein the first pump and the second pump deliver substantially the same volume of the first and second fluids, respectively, to the nozzle substantially simultaneously to allow the dispensing device to aspirate an approximately 1:1 mixture of the first and second fluids. 10. A fluid dispensing device comprising: (a) a bottle having a front side, a back side, a bottom, a first neck, a second neck, and a bottle coupling below a top of the first and second necks;(b) the bottle comprising a first compartment and a second compartment;(c) a dispensing head comprising a frame, a trigger, a first pump and a second pump;(d) a first dip tube fluidly connected to the first pump and an interior volume of the first compartment housing a first fluid;(e) a second dip tube fluidly connected to the second pump and an interior volume of the second compartment housing a second fluid; and(f) a nozzle which fluidly communicates with a first delivery tube and a second delivery tube, wherein the first and second delivery tubes having a void space between and are vertically aligned one above the other in a same vertical plane;wherein the first pump and the second pump deliver substantially the same volume of the first and second fluids, respectively, to the nozzle substantially simultaneously to allow the dispensing device to aspirate an approximate 1:1 mixture of the first and second fluids. 11. The fluid dispensing device of claim 10, wherein the trigger requires less than about 15 lbs of force for actuation. 12. The fluid dispensing device of claim 11, wherein the trigger includes a top portion which contacts a reinforcing flange on the frame which prevents reverse actuation motion of the trigger. 13. The fluid dispensing device of claim 10, wherein the bottle coupling is a snap coupling. 14. The fluid dispensing device of claim 10, wherein the trigger includes a bottom portion which is used as a single point of contact to support at least about 12 lbs of force. 15. The fluid dispensing device of claim 10, wherein the first pump is closer to a dispending end of the device and the second pump is closer to a rear end of the device so that the first pump and the second pump are in a front to back alignment. 16. The fluid dispensing device of claim 10, wherein the dispensing head further comprises a transmission member which translates actuation of the trigger to substantially simultaneous actuation of both the first and second pumps. 17.
