In the last few years there have been a quite steady increase in aluminum can consumption which means that the demand for beverages packaged in cans is only growing. But manufacturers of these cans and also beverages think not only about the demand but about how to make these cans more efficient and more enjoyable to the consumers.
That is where the aluminum can design comes in. Because these cans like any other thing that we can buy are designed and redesigned every so often to change their appearance and lure in more and more customers into buying these cans.
And not only the design of cans have evolved, but also different accessories for can recycling like aluminum can crusher, which has become a popular tool in each home for crushing aluminum cans for easier recycling of empty cans.
The first aspect of the design of the cans is their size. In many countries this size of a standard aluminum can changes. For example if in Australia the standard size for a can is 375 milliliters then in most of Europe it is 330 milliliter. But for beverages like energy drinks the standard in almost whole world is simply 500 milliliters of half a liter.
The next and probably one of the most important aspects in design of a can is the shape of the can itself. It has definitely changed over the years and continues evolving and changing even now.
In 1930s, when cans were first introduced as a beverage storing containers, they were shaped as cylinders with flat top and bottom. But at that time for some, these cans were very annoying invention because of the inconvenient opener at the top of the can. Thats why the so called cone tops were invented – cans with caps, that opened like milk bottles. They were shaped a little different with a conical tapered top. Nevertheless the regular cans were still more popular.
In 1959 a man invented a new way how to open cans. So can opening mechanism called pull-tab was born. This new invention eliminated the need for any tools to open cans and therefore made it so much easier to do so. But this new invention also posed the problem of sharp edges and litter after opening the can. So came the Sta-tab invention that we know now on every can we see. Around 1970 all of the cans had this new mechanism, but their shape didn’t really change until 1980s when the manufacturers started to make cans with narrowed top. The next change came in 1990 when the can manufacturers started to make them from lighter materials as the demand for cans started to grow very rapidly. This change also reduced the diameter of the can, cutting the manufacturing process and costs for it in half.
And even now can manufacturers are searching for new and more advanced technologies to not only cut the prices of production but to make the cans better and also to lessen their impact on the environment.
