ABSTRACT:
A spray bottle comprises a resilient transparent bottle having a removable top, a spray tube with an enlarged chamber on a lower end and a nozzle on an upper end, and a check valve on the bottom of the chamber. The chamber is slidingly disposed in a slide cavity within the top member with the spray tube extending through an aperture on an upper side thereof. The chamber is filled with a desired volume of liquid by immersing it to a selected depth in a fluid residing in a lower portion of the bottle, wherein the check valve is opened upon a downward displacement of the chamber. The spray tube is then raised to space the chamber from the surface of the liquid with the check valve acting to retain the quantity of fluid therein. A directional sealing ring disposed around an upper portion of the chamber allows the entry of air into the bottle during the upward displacement. The fluid in the chamber is subsequently discharged through the nozzle by squeezing the bottle.
