Abstract
A container vent control for a manually operated sprayer has a short flexible tubing section mounted within a cylindrical housing of the sprayer having a vent port. A vent probe on the trigger lever is aligned with the vent port and upon manual pressure applied to the trigger lever collapses or flexes the tubing section so as to be unseated from the vent port and open a vent into the interior of the container
