crown caps
Crown caps are metal bottle caps commonly used to seal glass bottles, especially for beverages like beer and soda. They have a crimped edge that securely fits over the bottle's neck, preventing leakage and preserving carbonation. Crown caps are typically made from steel and coated with a layer of paint or plastic to resist corrosion.
These caps often feature a printed design or logo, making them a popular choice for branding among beverage companies. The invention of the crown cap in the late 19th century revolutionized the bottling industry, allowing for easier and more reliable sealing compared to earlier methods like corks.
