Abstract:
1. A spray device comprising: a body defining a reservoir for holding content; a first chamber in selective communication with the reservoir; a piston slidably positioned in the first chamber; a first valve configured to control flow of the content from the reservoir into the first chamber; a second chamber; a vacuum plunger slidably positioned in the second chamber; a charger connected to the piston and the vacuum plunger and operable to displace the piston and the plunger to create a vacuum in the second chamber that imposes a force on the vacuum plunger and the piston, thereby pressurizing a quantity of the content in the first chamber; a spray nozzle in selective communication with the first chamber; a second valve configured to control flow of the quantity of the content in the first chamber out of the first chamber to the nozzle; and a spray actuator operable to generate a spray of the content from the nozzle by opening the second valve.
