The side walls having alternating peaks (22, 42) and valleys (24, 44). The peaks have apex ends (26, 46) which are disposed closely adjacent each other at the apex area to define a hinge region therebetween. Disposed along the apex area and on the side wall peaks are a plurality of outward projecting dimples (70, 72, 74) which are severable by a tangentially disposed knife blade to form a plurality of apertures (50, 52, 54).
