Craft of Bottle Caps

the application can be used free of charge

A bottle cap seals the top opening of a bottle. A cap is typically colorfully decorated with the logo of the brand of beverage, but not always. Plastic caps are used for plastic bottles, while metal with plastic backing is used for glass; the metal is usually steel.[citation needed] Plastic caps may have a pour spout. Flip-Top caps like Flapper closures provide controlled dispensing of dry products. Caps for plastic bottles are often made of a different type of plastic than the bottle.
