Abstract: A reverse suction inhibiting squeeze bottle discharge nozzle is secured to the filler neck of an otherwise conventional squeeze bottle. The reverse suction inhibiting squeeze bottle discharge nozzle provides a valve operative within the discharge passage of the nozzle together with an air return venting system and apparatus that cooperate with the valve to provide a vented air flow return into the bottle interior thereby restoring atmospheric pressure to the bottle interior. The venting of the air return venting system and the closure of the valve occur solely when the deformed squeeze bottle is released. As a result, the reverse suctioning of potentially contaminated material discharge back into the squeeze bottle interior is prevented.
