Update:28 Jan 2023

A water bottle cap is a device used to seal and open a water bottle, typically made of plastic or metal. It is designed to prevent spills and leaks and to maintain the freshness of the water inside the bottle. Some water bottle caps also have additional features such as a built-in straw or a carrying handle.

Some advantages of water bottle caps include:
They provide a secure seal for the bottle, keeping the contents fresh and preventing leaks.
They can be easily opened and closed, allowing for convenient drinking and refilling.
They can help prevent contamination of the water by keeping out dirt and other particles.
They can be made in different sizes and shapes to fit different bottle sizes.
Many water bottles are now being sold with sports cap, which makes it easier to drink while doing sports activities.
