A 병 (bottle) is a container typically made of glass or plastic, used for storing liquids. Bottles come in various shapes and sizes, designed for different purposes, such as holding beverages, oils, or chemicals. They often have a narrow neck and a mouth that can be sealed with a cap or cork to prevent spillage and contamination. Bottles are commonly used in everyday life, from water bottles for hydration to wine bottles for storing beverages. They can be recycled, making them an important part of environmental sustainability efforts. Many bottles are also designed for convenience, featuring easy-to-use openings and ergonomic shapes.
