A bottle is a container typically made of glass, plastic, or metal, used to hold liquids. Bottles come in various shapes and sizes, designed for different purposes, such as storing beverages, chemicals, or personal care products. They often have a narrow neck and a mouth that can be sealed with a cap or cork to prevent spills and contamination. Bottles are commonly used for drinks like water, soda, and juice, making them essential for hydration. The design of a bottle can also influence its usability, with features like ergonomic shapes and easy-to-open caps. Recycling and reusing bottles are important for environmental sustainability, reducing waste in landfills.
