ABSTRACT:
An improved closure insert is provided for throat region of a blow-molded container. This closure insert is provided with a rough perimeter and is permanently molded into the container throat region during container formation from a parison. The resulting seal resists loosening or disturbance when off-axis force or torque force is applied to the closure insert during container opening.
