  • Cap which can be packaged without danger of wedging
    Patent number: 3961719
    Abstract: For the capping of champagne bottles long skirt caps of frustoconical shape are used. These caps of thin metal foils are very fragile and bulky. Generally they are stacked one in another for shipping. To avoid any risk of the stacked caps being wedged into each other, their bottom is filled with a foamed thermoplastic washer. It is either detachable or injected cold.
