Abstract
A labyrinth ventilator is formed of a unitary structure including a housing formed of a front wall and perimetric walls, the back of the housing being open for communication with an air breather opening in a sidewall of a container. Air inlet apertures are located in the perimetric wall at the bottom of the housing. A set of transverse vanes, which serve as baffles to the flow of air, are positioned in alternating fashion along the interior of the housing to provide for a sinuous passage for the flow of air. A seal is secured within a channel disposed in the top and side portions of the rear edge of the housing for excluding rain at the junction between the ventilator and a container sidewall.
