<p>A heat shrinkable tubular closure sleeve (204) having a riveted longitudinal seam. The sleeve (204) is formed from a sheet (100) comprising two longitudinal margin portions (102, 104) having a strip (120) of oriented, heat shrinkable material therebetween. Specifically, the two margin portion (102, 104) are overlapped and joined by rivets (202), each rivet (202) passing through a hole (106, 114) in each of the overlapping margin portions (102, 104). Each margin portion (102, 104) comprises a laminate (108) having a metal layer (130) sandwiched between two plastic layers (132, 134) which do not shrink when heat is applied. Placing the tubular sleeve (204) over a cylindrical article (200) and applying heat to the sleeve (204), the strip (120) shrinks to reduce the radius of the sleeve (204) to effectuate a tight wrap around the article (200).</p> |
