We all love our fizzy soft drinks that satisfy our thirst, especially in the summer. They are undoubtedly among the most popular beverages in the world. These delightful soft drinks are a staple at parties and are favourites among the kids. But have you noticed the cold drink bottles carefully? Whether you go shopping in a mall or grocery store, you must have seen many cold drink bottles. But have you ever noticed that the bottom of these bottles is never flat? The bottom of the plastic cold drink bottles is always spike style. Whereas if you buy a water bottle, its bottom is always flat. Do you know the reason behind it? Let’s take a look.
People have been drinking beverages like buttermilk and lemonade for centuries to cool the body. But the history of cold drinks begins in the 17th century. Lemonade, made from lemon juice, water, and honey, was the first marketed soft drink. In 1676, the French company, Compagnie de Limonadiers in Paris, received a monopoly to sell lemonade. In the 17th century, Europeans attempted to imitate naturally carbonated spring water. In 1780, Johann Jacob Schweppe in Geneva developed the process of manually carbonating water.
The development of bottled soft drinks was a marvellous idea, making them a common sight in shops and households.
The unique shape and design of a cold drink bottle is an important part of its brand identity. But when it comes to design, the spike-style bottom is not just a style; there is design science behind it.
According to reports, the reason behind this is the gas in cold drinks. There is pressure on cold drinks putting further pressure on bottles with a flat bottom. The real reason behind such a design is that when a soft drink is cooled, its volume changes. As it contains gas, this kind of design, helps the bottle to adjust when the volume increases and the pressure is controlled. Along with this, the bottom part of these bottles is also made tighter than the top part. This allows the bottle to withstand pressure easily.
This specific type of bottle design is called corrugation.
