Claims87
A spray dispensing apparatus, comprising:
- a spray bottle for containing a first fluid;
- a manually operated spray head connected to said spray bottle, said spray head including a pump;
- a reservoir for containing a second fluid, said reservoir disposed within said spray bottle;
- a first fluid pickup tube disposed within said spray bottle and configured for withdrawing the first fluid from said spray bottle;
- a second fluid pickup tube disposed within said reservoir and configured for withdrawing the second fluid from said reservoir;
- a fluid metering and mixing device disposed within said spray bottle, said fluid metering and mixing device fluidly connecting said first fluid pickup tube and said second fluid pickup tube to said spray head,
- said fluid metering and mixing device including a mixing chamber, a first fluid inlet passageway for conveying the first fluid from said first fluid pickup tube into said mixing chamber, a second fluid inlet passageway for conveying the second fluid from said second fluid pickup tube into said mixing chamber, and a fluid outlet passageway for conveying mixed fluid from said mixing chamber into said spray head,
- said first fluid inlet passageway provided with a fluid checking valve configured for allowing flow of the first fluid into said mixing chamber when suction is applied to said mixing chamber by operation of said spray head while preventing back flow into said first fluid pickup tube during non-operation of said spray head, and said second fluid inlet passageway is provided with a fluid metering and checking valve including a metering chamber containing a metering ball configured for delivering a predetermined volume of the second fluid into said mixing chamber when suction is applied to said mixing chamber by operation of said spray head while preventing back flow into said second fluid pickup tube during non-operation of said spray head,
- said fluid metering and checking valve including a lower funnel-shaped passageway portion cooperating with said metering ball for defining a first one-way valve for allowing the second fluid to be conveyed into said metering chamber while preventing reverse flow back into said second fluid pickup tube, said fluid metering and checking valve including an upper funnel-shaped passageway portion cooperating with said metering ball for defining a second one-way valve having a reverse orientation relative to said first one-way valve, said second one-way valve positioned a predetermined distance from said first one-way valve defining said metering chamber having a fixed volume therebetween, said second one-way valve allowing the predetermined volume of the second fluid to be metered into said mixing chamber before stopping the flow of the second fluid into said metering chamber;
- a first air passageway for venting said spray bottle;
- and
- a second air passageway for venting said reservoir.

A trigger pump spray dispensing apparatus, comprising:
- a spray bottle defining a first fluid reservoir for containing a first fluid, said spray bottle including a threaded neck portion;
- a second fluid reservoir for containing a second fluid, said second fluid reservoir disposed within said spray bottle;
- a fluid mixing device disposed within said spray bottle for mixing together the first and second fluids to form a mixed fluid, said fluid mixing device being entirely located within said neck portion of said spray bottle;
- a first fluid pickup tube connected to said mixing device and extending into said spray bottle for withdrawing the first fluid from said first fluid reservoir into said mixing device;
- a second fluid pickup tube connected to said mixing device and extending into said second fluid reservoir for withdrawing the second fluid from said second fluid reservoir into said mixing device;
- a manually operated trigger pump type spray head threadedly connected to said spray bottle for receiving mixed fluid from said fluid mixing device and then dispensing the mixed fluid;
- a connecting tube for connecting said fluid mixing device located inside spray bottle to said spray head located outside said bottle;
- a first passageway for venting said first reservoir;
- and
- a second passageway for venting said second reservoir.
