, and was an investor in the Seaquist company, an early manufacturer of sprayers and closures. Initially, the brittle nature of early plastics required that sprayers be packaged in a cardboard box, and the sprayer inserted in the glass Windex bottle by the consumer. The cost in the manufacturing sprayers was also a factor; consumers would reuse the sprayers with bottle after bottle of glass cleaner. As plastics improved and the cost of sprayers dropped, manufacturers were able to ship products with the sprayer already in the bottle. In the late 1960s, spray bottles with trigger-style actuators appeared and quickly became popular, as this design was less fatiguing to use. The original pump-style bottle remained more popular for applications like non-aerosol deodorants, where size was a factor and repeated pumps were not required.

Modern spray bottles

Unlike the rubber bulb dispenser which primarily moved air with a small amount of fluid, modern spray bottles use a

that acts directly on the fluid. The pump draws liquid up a siphon tube from the bottom of the bottle and forces it through a nozzle. Depending on the sprayer, the nozzle may or may not be adjustable, so as to select between squirting a stream, aerosolizing a mist, or dispensing a spray. In a spray bottle, the dispensing is powered by the user's efforts, as opposed to the spray can, in which the user simply actuates a valve and product is dispensed under pressure. Several designs have been developed. Some of the pumping mechanisms of spray bottles are similar to those of pump dispensers which are used for more viscous products.
