Precoating of aluminum can sheet - Patent 3832962". www.freepatentsonline.com . Retrieved 2009-07-20. Previously, while on a family picnic, Mr. Fraze had forgotten to bring a can opener and was forced to use a car bumper to open a can of beer. Thinking there must be an easier way, he stayed up all night until he came up with the pull tab. [16] Pull-tab cans, or the discarded tabs from them, were colloquially called "pop-tops". [17] Most manual can openers are designed for right-handed use. If some of your family members are left-handed, an electric opener or a one-handed manual opener that can be used with either hand may be the most versatile. Some openers are designed just for left-handed users, but they can be harder to find and more expensive than right-handed or ambidextrous models. In New Zealand the standard can size is 355ml, although Coca-Cola Amatil changed some of its canned drinks to 330ml in 2017. [7] North America
The early pull-tabs detached easily. In 1976, the Journal of the American Medical Association noted cases of children ingesting pull-tabs that had broken off and dropped into the can. [23]
The best can openers for 2022 are:
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.
In 1935, [3] the Felinfoel Brewery at Felinfoel in Wales was the first brewery outside the US to commercially can beer. Prior to this time, beer had been available only in barrels or in glass bottles. From this time, lightweight tin cans could be used. Felinfoel was a major supplier to British armed forces abroad in the Second World War. Cans saved a great deal of space and weight for wartime exports compared to glass bottles and did not have to be returned for refilling. These early cans did not have a pull tab, being equipped instead with a crown cork (beer bottle top). From the 18th century until the early 20th century Wales dominated world tinplate production, peaking in the early 1890s when 80% of the world's tinplate was produced in south Wales. [4] 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. One of the more recent modifications to can design was the introduction of the "wide mouth" can in the late 1990s. [34] The American Can Company, now a part of Rexam, [35] and Coors Brewing Company have owned wide mouth design patent (number D385,192) [36] since 1997. Other companies have similar designs for the wide mouth. Ball Corporation's from 2008 has a vent tube to allow direct airflow into the can reducing the number of gulps during the pour. [37] Press button can [ edit ] Beer can collecting was a minor fad in the late 1970s and 1990s. However, the hobby waned rapidly in popularity. The Beer Can Collectors of America (BCCA), founded in 1970, was an organization supporting the hobby, but has now renamed itself Brewery Collectibles Club of America to be more modern.

Retrieved 2012-08-07.This opener is top-rated by users for seniors and arthritic hands, so you can rest assured that comfort is the priority of the tool's design. Even though the can opener is mostly plastic, we found that it felt very durable and couldn't imagine it breaking with normal kitchen use. As for cleaning, it is dishwasher safe, but it is just as efficient to wash by hand. Early metal drink cans had no tabs; they were opened by a can-piercer or churchkey, a device resembling a bottle opener with a sharp point. The can was opened by punching two triangular holes in the lid—a large one for drinking, and a second smaller one to admit air. Singh, S. P.; Gorzynski (July 1989). "Effect of Vibration as a Cause of Leakage in aluminum Beer Cans in Palletized Loads". J. Testing and Evaluation. 26 (4). 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.
