SAFETY MECHANISM FOR DISPENSING APPARATUS.

摘要

A dispenser (10) for mixing together multiple fluids, such as foam components and dispensing the mixed fluids includes a body portion (12) of the dispenser with fluid entrances and an exit. A handle (14) extends from the body portion to facilitate grasping and operation by a user. A flow control valve (16) is positioned in the body portion for controlling flow of foam components entering the dispenser mixing chamber. The trigger (24) is movably mounted to the body portion in opposition to and spaced apart from the handle. A safety (26) 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 (54) 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.
