First Claim
1. A vacuum foam remover comprising a nozzle extending across the path of containers as they move between filling and closing stations, support means supporting said nozzle above said path, vacuum means for drawing a vacuum through said nozzle, and a substantially rectangular frame at the bottom of said nozzle extending across said path, first and second parallel sides of said frame being substantially transverse to said path and substantially longer than the third and fourth sides of said frame.

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.
