Patent ID: 7059798

Claim:
A traffic channelizer device comprising a deformable hollow plastic drum having a side wall and an open bottom, a radially outwardly and axially downwardly tapering skirt portion adjacent the open bottom for resisting pull out of the drum from a ballasting collar adapted to be inserted over the drum, and a plurality of circumferentially spaced radially outwardly and axially downwardly tapering stiffening ribs integral with the skirt portion, the skirt portion having a relatively wide flat side with outwardly protruding corners adjacent a bottom edge of the drum to resist rolling of the drum when tipped on its side, the skirt portion having a curved portion adjacent the bottom edge of the drum diametrically opposite the flat side, the stiffening ribs progressively increasing in size and radial extent of protrusion from the skirt portion from the approximate midpoint of the curved portion to the protruding corners to create a substantially uniform diameter offset around the drum toward the flat side of the skirt portion, whereby when the ballasting collar is placed over the drum, the stiffening ribs will cause the ballasting collar to be slightly offset from the axial center of the drum in the direction of the flat side.
