ABSTRACT:
In order to avoid foaming which may influence the closing zone of containers for products of the kind that may foam during the filling procedure, a method is provided according to which an anti-foam medium in the shape of a thin surface layer is applied in the closing area of the container, or container blank, resp., if desired, close to said area on the inner surface of the container. Such application is preferably carried out before the blank is set up as a container. A device for use in the method may comprise a roll (12) provided with one or a number of grooved zones (9',10'). Roll (12) is mounted on a shaft (13) to be rolled in contact with the inner surface of a web (11) from which the container blanks are manufactured, preferably while said web is advanced past roll (12).
