1. A cover defining a cavity therein:
the cover including a central panel and a side panel,
the central panel having an exterior surface, an edge and an edge portion bordering along the edge of the central panel,the side panel having an exterior surface, an edge and an edge portion bordering along the edge of the left side panel,the central panel mechanically coupled to the side panel along by a mechanical coupling of the edge portion of the central panel to the edge portion of the left side panel forming an elongate joint seam therebetween along which the exterior surface of the central panel is discontinuous with the exterior surface of the left side panel,an elongate bead of hardened extruded material extending longitudinally of the joint seam and overly the joint seam,the bead having a surface extending circumferentially thereabout normal a longitudinal of the bead, the surface consisting of a hidden-from-view interior surface and an outwardly directed visible exterior surface with the interior surface and the exterior surface merging circumferentially into each other,the bead interior surface bonded to both the edge portion of the central panel and the edge portion of the side panel to secure the edge portion of the central panel to the edge portion of the left side panel,the bead interior surface spanning the joint seam, the bead interior surface adhesively bonded to the edge portion of the central panel proximate the joint seam on a first side of the joint seam and adhesively bonded to the edge portion of the side panel proximate the joint seam on a second side of the joint seam,the bead exterior surface spanning between the exterior surface of central panel on the first side of the joint seam and the exterior surface of the side panel on the second side of the joint seam and hiding the elongate joint seam along its length from visual view outwardly from the cover. |
