Plain lids (known as shells) are stamped from a coil of aluminum, typically alloy 5182-H48, and transferred to another press that converts them to easy-open ends. This press is known as a conversion press which forms an integral rivet button in the lid and scores the opening, while concurrently forming the tabs in another die from a separate strip of aluminum. The similarly designed "Easy-open ecology end" was invented by Ermal Fraze and Omar Brown. 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. [32]Into the 1970s the pull-tab was widely popular, but its popularity came with the problem of people frequently simply discarding the pull-tabs on the ground, creating a potential injury risk especially to the feet or fingers. In the 1960s, at least one inventor attempted to solve the litter problem, by having the tab be retained by a stationary key that would wrap the tab around itself, which was unsuccessful commercially. [18] An empty aluminum can weighs approximately one-half ounce (14g). There are 34 empty aluminum cans to a pound or 70 to a kilogram. [11]

Can filling lines come in different line speeds from 15,000 cans per hour (cph) up to 120,000 cph or more, all with different levels of automation. For example, lid feeding alone starts with manual debagging onto a simple v-chute connected to the seamer up to fully automated processes with automatic debagging and lid feeding of lids combined with automatic roll depalletizers for filling debaggers by robots. The problem of the discarded tops was initially solved by the invention of the push-tab. Used primarily on Coors Beer cans in the mid-1970s, the push-tab was a raised circular scored area used in place of the pull-tab. [19] It needed no ring to pull up; instead, the raised aluminum blister was pushed down into the can using one finger. A small unscored section of the tab prevented it from detaching and falling into the can after being pushed in. Push-tabs never gained wide popularity because while they had solved the litter problem of the pull-tab, they created a safety hazard where the person's finger upon pushing the tab into the can was immediately exposed to the sharp edges of the opening. A feature of the push-tab Coors Beer cans was that they had a second, smaller, push-tab at the top as an airflow vent. "Push-tabs" were introduced into Australia from around 1977 and were locally known as "pop-tops", before being replaced later by the Stay-on-tab. [20] The safety and litter problems were eventually solved later in the 1970s with Daniel F. Cudzik's invention of the non-removing "Stay-Tab".tnichss, Tess Nichol Reporter, NZ Herald tess nichol@nzherald co nz (2017-09-21).

with a physical or mental impairment which has a long-term and substantial adverse effect upon his/her ability to carry out everyday activities; Another variation on the drink can is the "full aperture end", where the entire lid can be removed – turning an aluminum can into a cup. Crown Holdings first designed the "360 End" [39] for use by SABMiller at the 2010 FIFA World Cup in South Africa. [40] It has been used by Anheuser-Busch InBev in China [41] and Brazil [42] and by the Sly Fox Brewing Company [43] in the United States. 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] In Hong Kong most cans are 330ml – in the past they were usually 355 or 350ml. 200ml has also become available. Some beers and coffees are, respectively, sold with 500-ml and 250-ml cans. For all their convenience, the original pull-tabs created a large amount of controversy, namely for their environmental impact. For 10 years people opened cans by ripping off the pull-tabs and discarding them. The discarded tabs were a danger to wild animals, which suffered death from ingesting the metal pieces. There were also cases of people choking on the tabs, having dropped them into their can by mistake. The stay-on tab solved this dilemma and is the opening device we know today. What does the ring pull market look like today?In 1959, the recyclable aluminum can was introduced to the market in a 7 oz. size by the Adolph Coors Company. [5] It’s easy to forget what a huge difference a simple invention such as the ring pull has made to everyday life. Prior to its existence, people had to carry special can openers every time they wanted to open a can of beer or coke – which was highly inconvenient at times. While canning food and drink was already popular, accessing the contents of the can was not so straightforward. 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] Cans are filled before the top is crimped on by seamers. To speed up the production process filling and sealing operations need to be extremely precise. The filling head centers the can using gas pressure, purges the air, and lets the drink flow down the sides of the can. The lid is placed on the can, and then crimped in two operations. A seaming head engages the lid from above while a seaming roller to the side curls the edge of the lid around the edge of the can body. The head and roller spin the can in a complete circle to seal all the way around. Then a pressure roller with a different profile drives the two edges together under pressure to make a gas-tight seal. Filled cans usually have pressurized gas inside, which makes them stiff enough for easy handling. Without the riveted tab the scored section of the can's end would be impossible to lift from the can.

Full aperture end [ edit ] The Finnish brewery Fat Lizard uses "topless" cans where the entire lid is removed when opening the can. As early as 1922, inventors were applying for patents on cans with tab tops, but the technology of the time made these inventions impractical. [15] Later advancements saw the ends of the can made out of aluminum instead of steel.
