<p>Carrier stock (30) for machine application to substantially identical cans (12) of a newer type having an end with a chime (16) of a relatively small diameter, a cylindrical side wall (18) of a relatively large diameter, and a generally frusto-conical wall (20) between the cylindrical wall (18) and the chime (16) is formed from a single sheet of resilient polymeric material and has integrally joined band segments (34, 38) defining can receiving apertures (32). These include generally longitudinal outer segments (34), each having inner (56) and outer (54) edges associated with one such aperture (32). When the stock (30) is unstressed, two lateral portions (58) of the inner edge (56) are concave, two corresponding lateral portions (62) of the outer edge (54) are convex, and a central portion (60) of the outer edge (54) is concave. A central region (52) between the lateral portions (58) may have an integrally joined tear-open tab (50). Certain generally transverse segments (39, 42), which join inner segments (38), may have curved edges (74, 76) when the stock (30) is unstressed.</p> |
