  • Vacuum foam remover
    Patent number: 4520528
    Abstract: A vacuum nozzle draws off foam from the headspace of filled containers as they approach container closers. The nozzle has a substantially rectangular head at its lower end, preferably turned at an angle to the path of the containers. From the head depends a pair of parallel scraper-like blades of rubber-like material. Spaced slits extend upward from the bottom edges of the blades. The upper end of the nozzle leads to a source of vacuum which includes means for salvaging the liquid content of the foam for re-use.
