Closure systems are mechanisms designed to securely seal or close an object, preventing unwanted access or contamination. They are commonly used in various applications, such as packaging, containers, and even in technology. Examples include zipper systems on bags, screw caps on bottles, and snap closures on food containers. These systems can vary in complexity, from simple designs like Velcro strips to more advanced options like electronic locks. The primary goal of closure systems is to ensure safety, maintain freshness, and provide convenience for users. Properly designed closure systems enhance functionality and user experience across many products.
