초록 ▼

A hand-actuated multiple-container trigger sprayer includes a sprayer head assembly removably connected to a plurality of fluid containers. The sprayer head assembly has an outer housing, a nozzle attached to the housing, pump mechanism enclosed within the housing, and tubing fluidly connecting each of the plurality of fluid containers with the pump mechanism in the housing. A trigger or lever actuates the pump mechanism to draw fluid through the tubing from each of the plurality of fluid containers and to discharge the fluid through the nozzle. A metering device is located between the fluid containers and the pump mechanism and is accessible externally from the housing to selectively control the amount of fluid drawn from the containers. The metering device includes flow paths to the pump mechanism for each of the fluid containers. The diameter and length of at least one of the flow paths can be controlled to selectively control the amount of fluid drawn from the fluid containers.
