If we do not want to drink directly from the can or pour its contents into another container, the purpose of the object is to allow us to insert a straw to consume the drink. Surely we have all played with the rings of soda cans, turning them into necklaces or using them to form the alphabet. Whether they are made of metal or have different colors, these rings and the cans themselves are a display of perfect engineering.
The drinks provide a pleasant and refreshing taste, especially when they are carbonated and come in a 33 centiliter can that can be easily stored in the refrigerator. The sound when the can is opened is very characteristic and usually evokes positive memories. However, once opened, what is the function of the ring hole?
The beginnings of the rings used on soft drink cans.
Every event has a reason for being, and in this case one should not go back too far. In 1935, the Gottfried Krueger Brewing Company introduced the first commercial beer can to the market. Named Finest Beer, it was the first beer in the world to be sold in a hermetically sealed can.
An essay that spread to all the countries of Europe and, obviously, to the United States. Tin cans were very common and now so are soda cans, always with the need of a can opener to be able to break the aluminum.
In 1965, an American engineer named Ermal C. Fraze had a brilliant idea. During a picnic he realized he didn’t have his can opener with him, so he had to use a car bumper to open a can. From that moment on, he decided to look for a solution to this problem and created the Easy-Tab, an opening built into the can that does not require anything external to be opened.
In 1966, the first beverage can was introduced in Spain. It was during this period that Cervezas Cruz Blanca decided to launch a new brand called Skol International Lager. Soon, the rest of the Spanish breweries also adopted this type of packaging to adapt to the changes and new trends of the moment.
During the 1980s, an improvement was made to the can system with the implementation of the Stay-on Tab, a mechanism that prevented the ring from coming loose from the lid. However, it is still unclear what the purpose of the hole in the ring is.
What is the reason behind the hole in the can rings?
The main purpose of the hole in a can is simply to facilitate cleaning and care when drinking. For those who are more cautious and do not want to drink directly from the can or pour the contents into a glass, they can use a straw to drink through the hole. This prevents the drink from spilling, keeping your mouth away from any possible harmful substances. In the end, it all depends on personal preference, just like the various colors of the rings on the cans.
