CA 2151982

A bleeder valve venting system includes a bleeder valve that is provided, and adapted to mount through a lid aperture, the valve having an enlarged upper cap portion, a cylindrical intermediate portion which extends through the lid aperture, and a semi-spherical lower working portion. A central axial through-bore extends downward through the cap and intermediate portions, and a slit is provided to extend upward into the lower valve portion and communicate with the through-bore. The lid aperture is sized to admit the valve with interference, whereby establishing a liquid tight seal between the valve body and portions of the lid defining the aperture. The valve is composed of resilient material and the slit is dimensioned to open to a width sufficient to admit air when a pressure differential exists between the inside and outside of the container. As the slit opens, the lower working valve portion is compressed against inside surfaces of the lid, and, upon equalization in air pressure, the working valve portion reacts to force the slit closed.
