The evolution of beer cans from the simple to the elementary
Exactly ’82 ago foamy drink was first introduced commercially in metal can. American Brewery Gottfried Krueger Brewing Company has released a test batch of canned “Cream Ale Kruger” in Richmond. New product turned out to be a resounding success: in the summer, the company increased sales in the five and a half times.
Of course, over the years the appearance of a beer can has changed significantly. Let’s go through the main evolutionary milestones.
The main advantage of the iron cans in front of a bottle – easy to transport. Banks can be stacked in piles, without fear that the pits on the roads spoil most of the goods.
Innovation Krueger Brewery in essence is no different from an ordinary tin can. Initially it was opened in the usual beer can opener and poured the contents into a glass. Then you come up with a special device to which it was possible to pierce a hole in a steel cover. Instructions placed on the label.
In the late 40-ies Gluek company has developed a new design: the top of the crater appeared in the form of a screw cap.
It was much simpler to open a can, but this model was a major drawback. To put one can to another was no longer possible. In 1955, the brewery Pabst solved the problem of adapting the cover directly to the can and giving up the funnel.
Old-fashioned cans, however, were also in vogue. So the question is how to get to the beer without using a can opener. In 1959, the engineer Ermanno Frenzy found the answer. Once he arrived at the family picnic, leaving opener at home. He immediately sat down to design the elementary method for unsealing jars.
The fruit of his labors became Valve opener. Freyz issued patent and sold the rights to the packaging company Alcon. Beer Company Pittsburgh Brewing Co, which appeared first on the market with such a device, created a furor. By 1965, more than 75% of all cans were equipped with Freyza invention.
When pulled, the tab sometimes left sharp edges that could cut lips and tongues. Worse, sometimes the tab would break off before removing the entire metal strip, creating thirsty and angry non-drunks. There was also the new problem of litter; thin pieces of metal appeared in the wake of any drinking session. It was clear that the technology was far from perfect.
In 1975, engineer Daniel Cudzik invented version of the petal, which remained on the can after opening the lid. In fact, today the banks are doing almost the same as those offered by Cudzik.
