Abstract
A member that positions a vent disc in an end of a container is provided. The member has at least one projection extending from the vent disc virtually solely for positioning the vent disc in its secured position in the end of a container. The at least one projection is located in the center portion of the vent disc and can be one projection, which extends from the vent disc at the center point of the vent disc. The projection can be of a geometrical shape that facilitates gripping and handling of the vent disc, including rectangular, ellipsoidal or cylindrical shapes.
