A jar with a valve and a ring is an invention that has made life easier not only for beer lovers.

Aluminum can key
Beer can

Ermal Cleon Freize was born in 1913. He spent his youth on a farm in Indiana, and in the 1940s he moved to Dayton, Ohio, where he earned his living in various mechanical and painting jobs. In 1949, Frase founded the small Reliable Tool and Manufacturing Co. ("Reliable Tools and Production"), where he was the only employee. The business was not very profitable, but enough to live on. Frase even patented several small inventions, and also graduated from General Motors Technical School and received an engineering degree.

By the late 1950s, the still small company's customers included such giants as General Electric, Ford, Chrysler, and even NASA. One day in 1959, Ermal Freize, or simply Ernie to his friends, decided to have a picnic in nature with his family and friends. When the snack was already cut and the food was ready, Ernie took out one of the latest technological advances of those times from the trunk - beer packed in aluminum cans. Here a slight disappointment awaited him: it turned out that none of those present had thought to take a can opener with them.

However, Ernie was not in vain a skilled mechanic: he quickly came up with a way to open cans with the help of improvised tools and a car bumper (although it turned out more foam than beer). But he remembered this incident - after all, such a trifle almost ruined a wonderful weekend. A couple of months later, Fraze, suffering from insomnia, decided to occupy his head with some everyday problem. The case with the banks came to mind by itself.

Later, the inventor said: "I did not invent self-opening cans. I just suggested a way to attach a key to the lid of the can."

Ernie's solution was simple - the key was attached to the center of the lid with a regular rivet. The first option turned out to be not very successful - the lever key punched a hole in the bank with sharp edges, which could be cut. To solve this problem, Freise proposed to loosen part of the cover by making preliminary non-through cuts on it.

In 1963, the inventor received a patent and offered it to Alcoa, a can manufacturing company. The company took a chance and won - by 1965, more than 75% of all cans sold in the US were equipped with a key to open.

In the 1970s, the can opening system was improved - the key was made non-removable, since the sharp-edged aluminum "tags" were very polluting. During this time, Frase's company, renamed Dayton Reliable Tool, became one of the leading suppliers of industrial equipment for the production of such cans, and by 1980, the once small firm had annual income of more than half a billion dollars.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Ultrasound of the new generation CrystalLive from Samsung 23.06.2018

Samsung Electronics announced that its medical division Samsung Medison has developed a new generation of ultrasound technology that will enable, among other things, more accurate fetal diagnosis.

The new solution, called CrystalLive, allows you to recreate a three-dimensional image of the fetus in the womb or various internal human organs.

The developers claim that Samsung's next-generation ultrasound will allow mothers to see a much more detailed image of their children before birth, and doctors will be able to improve the accuracy of diagnosis in identifying various diseases.

Samsung said the new WS80A ultrasound machine, which will use CrystalLive technology, will be released initially in South Korea, Europe and the US. Later the device will appear in other countries of the world.
