People have been using soft drinks to keep the body cool for decades. The history of cold drinks begins in the 17th century. At that time, lemonade made from lemon juice, water and honey by the French company 'Company de Limonadiers' flooded the market. Later, other European countries started using carbonated water in soft drinks. In 1780, Johann Jacob Schewipp in Geneva first discovered the process of using carbonates in water.

The unique shape and design of cold drink bottles is important for advertising and brand identity. But not only that, there is science behind the soft drink's notched back.

According to various reports, the bottles are made this way because of the gases contained in the soft drink bottles. The gas is introduced by pressing down on the cold drink, which puts more pressure on the flat bottles. As a result, the bottle is likely to burst. But if the bottle is grooved, the volume of the bottle changes due to excess pressure. As a result, the consistency of the bottle is correct. For the same reason the lower part of the bottles is stiffer than the upper part. This particular type of bottle design is called 'corrugation'.
