A dispenser for mixing together multiple fluids, such as foam components and dispensing the mixed fluids includes a body portion of the dispenser with fluid entrances and an exit. A handle extends from the body portion to facilitate grasping and operation by a user. A flow control valve is positioned in the body portion for controlling flow of foam components entering the dispenser mixing chamber. The trigger is movably mounted to the body portion in opposition to and spaced apart from the handle. A safety for preventing unintended operation of the dispenser is movably mounted to and extends lengthwise of the trigger that is always biased into a safety position. The safety has an arm for preventing movement of the trigger sufficient to cause unintended operation of the flow control valve, and the safety may be disengaged by the same single-handed action used to actuate the dispenser to dispense the mixed fluids.

1. A dispenser for mixing together foam components to form an expandable foam and dispensing the foam, comprising:a body portion including foam component entrances and a foam mixing chamber; a handle extending from said body portion to facilitate grasping and operation by a user, the handle including a stop surface; a flow control valve disposed in said body portion for controlling flow of foam components entering the dispenser mixing chamber; a trigger pivotally mounted to said flow control valve and disposed in opposition to and spaced apart from said handle, whereby movement of the trigger opens and closes said flow control valve to respectfully permit flow of said foam components through said dispenser and prevent flow of said foam components through said dispenser; and a safety for preventing unintended operation of said dispenser, said safety being movably mounted to and extending lengthwise of said trigger, said safety having a projecting arm portion located in opposition to said handle stop surface for preventing substantial, unintended movement of said trigger sufficient to cause unintended operation of said flow control valve.
