ABSTRACT:
An ergonomic trigger sprayer comprising a spraying mechanism including a nozzle and a trigger for connection to a container holding the liquid; a housing having a mounting portion for attachment to the container, the housing enclosing the spraying mechanism when mounted to the container and having opposed front and rear ends, and a hand positioner affixed to the rear portion of the housing. The hand positioner is for providing pressure contact with the dorsal web of the hand of a user between the thumb and the index finger when the user grips the container and pulls the trigger so that the container and the hand and wrist of a user are held in substantial alignment during spraying operations. The hand positioner includes a bottom wall that is in pressure contact with the dorsal web of the hand of the user during spraying operations.
