Kondakow, Mikolaj (1951-09-11). "Patent CA476789: Crimped cap removers". Canadian Patents Database . Retrieved 2017-10-04. In 1959, Ermal Fraze devised a can-opening method that would come to dominate the canned drink market. His invention was the "pull-tab". This eliminated the need for a separate opener tool by attaching an aluminum pull-ring lever with a rivet to a pre-scored wedge-shaped tab section of the can top. The ring was riveted to the center of the top, which created an elongated opening large enough that one hole simultaneously served to let the drink flow out while air flowed in. Drinks brands such as Coca-Cola have latched on to the ring pull with great enthusiasm. The beverage giant currently distributes 1.6 billion global servings per day, most of them in cans and bottles. The ring pull has transformed the distribution of Coca-Cola and other drinks companies – including most beer brands – offering a hassle-free way for consumers to open cans.

Retrieved 2013-10-05.Mikolaj Kondakow and James Wong of Thunder Bay, [ dubious – discuss] Ontario, Canada invented the pull tab version for bottles in or before 1951 (Canadian patent 476789). [22] In 1962, Ermal Cleon Fraze of Dayton, Ohio, United States, invented the similar integral rivet and pull-tab version (also known as ring pull in British English), which had a ring attached at the rivet for pulling, and which would come off completely to be discarded. He received US Patent No. 3,349,949 for his pull-top can design in 1963 and licensed his invention to Alcoa and Pittsburgh Brewing Company, the latter of which first introduced the design on Iron City Beer cans. The first soft drinks to be sold in all-aluminum cans were R.C. Cola and Diet-Rite Cola, both made by the Royal Crown Cola company, in 1964. An empty aluminum can weighs approximately one-half ounce (14g). There are 34 empty aluminum cans to a pound or 70 to a kilogram.

Its patent application was also filed in 1975, less than two months after the expiration of Bajada's patent. [31] This design, like Cudzik's, uses a separate tab attached to the upper surface as a lever to depress a scored part of the lid, which folds underneath the top of the can and out of the way of the resulting opening, thus reducing injuries and roadside litter caused by removable tabs.

In Canada, the standard size was previously 12 Imperial fluid ounces (341ml), later redefined and labelled as 341ml in 1980. This size was commonly used with steel drink cans in the 1970s and early 1980s. However, the US standard 355ml can size was standardized in the 1980s and 1990s upon the conversion from steel to aluminum. Some drinks, such as Nestea, are sold in 341ml cans. Full-top pull-tabs were also used in some oil cans and are currently used in some soup, pet food, tennis ball, nuts, and other cans. with a physical or mental impairment which has a long-term and substantial adverse effect upon his/her ability to carry out everyday activities; Turner, Terence (2001).

Apple Patents reveal how the Aluminum Unibody MacBook Enclosure is made from Recycled Pop and Beer Cans & more". Patenly Apple. March 2021.The idea for the ring pull, sometimes known as the pull-tab, came about out of necessity. Before its invention, cans were opened using implements called churchkeys. However when people inevitably found themselves without such an instrument, they were unable to open their cans. It was while having a picnic in 1959 that Ermal Fraze, from Dayton, Ohio, found himself unable to get into his beer can. He decided there must be a solution to this dilemma, and so set about designing an opener on the can itself. Lopez, F.; Cabrera, C.; Lorenzo, M. L.; López, M. C. (2002).

The beverage can be recycled, and clean aluminum has residual market value, but recycled cans still need to be diluted by up to 50% virgin aluminum because the sides and tops of the can are of different alloys. The acronym UBC, for used beverage container, is employed by such companies as Apple, Inc for reference to the material of its portable laptop cases.
