DUAL CHAMBER SPRAY DISPENSER WITH A SINGLE DELIVERY TUBE

摘要

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.

主权项

1. A fluid dispensing device comprising:
(a) a bottle having a front side, a back side, a bottom, a neck top and a bottle coupling portion below the neck top; (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; (f) a single delivery tube fluidly connected to the first pump and the second pump; and (g) a nozzle which fluidly communicates with the single delivery tube; wherein the first fluid and second fluid first come into contact with one another in the single delivery tube.
