A "pull tab" is a small metal or plastic tab that is attached to the top of a can, typically used for beverages like soda or beer. When pulled, it creates an opening in the can, allowing the contents to be easily accessed. This design is convenient and eliminates the need for a can opener. Pull tabs are commonly found on aluminum cans and are designed for single-use. They are part of the can's packaging, which is often made from materials like aluminum or steel. The pull tab mechanism has become a standard feature in the beverage industry, enhancing user experience.
