  • Container with lid for effervescent products
    Patent number: 4545498
    Abstract: A container for effervescent products, especially kefir, is covered by a lid having openings for the escape of the gas. A layer, covering the opening, is affixed to the surface of the lid. A passage leading to the exterior and connected with the opening is disposed between this layer and the lid. By means of this arrangement, the gas can escape from the container without difficulty, but germs and dust cannot enter the container from the top since the opening is covered.
