Crown Corks

The „crown cork“ has been invented by William Painter in Baltimore (USA) way back in 1892. The ingenious idea behind this bottle cap has remained unchanged until today. However, the method of production of crown corks passed through revolutionary changes and continous improvement since its patenting. Therefore, DKF nowadays offers crown corks in various different specifications regarding sheet thickness, lacquer systems and liner materials. Applicable for reusable and disposable glass and PET bottles, DKF® crown corks are supplied worldwide.
