CARRIER STOCK FOR CANS HAVING SEVERE TAPER BETWEEN BODY AND TOP CHIME; CARRIER APERTURES PROFILED TO CONTACT CAN TAPER BELOW CHIME

摘要

Carrier stock for machine application to substantially identical cans of a newer type having an end with a chime of a relatively small diameter, a cylindrical side wall of a relatively large diameter, and a generally frusto-conical wall between the cylindrical wall and the chime is formed from a single sheet of resilient polymeric material and has integrally joined band segments defining can-receiving apertures. These include generally longitudinal outer segments, each having inner and outer edges associated with one such aperture. When the stock is unstressed, two lateral portions of the inner edge are concave, two lateral portions of the outer edge are convex, and a central portion of the outer edge is concave. A central region between the lateral portions may have an integrally joined tear-open tab. Certain generally transverse segments, which join inner segments, may have curved edges when the stock is unstressed.
