Stoppers are devices used to seal or close openings in containers, preventing the contents from spilling or becoming contaminated. Commonly made from materials like rubber, cork, or plastic, stoppers are often found in bottles, jars, and tubes. They come in various shapes and sizes to fit different types of containers, ensuring a secure closure. In addition to their practical uses, stoppers can also serve decorative purposes. For example, wine bottle stoppers can be designed with unique shapes or materials, adding an aesthetic touch to the presentation of the bottle. Overall, stoppers play a crucial role in both functionality and design.
