A portable dispensing device, typically constructed from plastic or metal, with a capacity of approximately two gallons, designed for the application of liquids such as herbicides, pesticides, fertilizers, and cleaning solutions. These devices feature a hand-operated pump to pressurize the contents, a wand for directing the spray, and a nozzle to control the spray pattern. A common application is in residential gardening, where a user may need to treat a small to medium-sized area with insecticides to protect plants from pests.
Such tools provide an efficient and targeted method for liquid application, reducing waste and minimizing drift compared to alternative methods like watering cans. Their portability allows for easy maneuverability within gardens and smaller agricultural settings. The development of these tools has evolved from basic pump-action mechanisms to include features like pressure relief valves and adjustable nozzles for greater control and safety. This facilitates more precise and economical use of treatment solutions.
