Method and device for filling containers with carbonised filling material and subsequently closing the filled containers

Abstract

The invention relates to a method for filling a container (13, 32) with carbonised liquid filling material and for closing the filled container, in which in a filling station (10, 30) the filling material is introduced into the container (13, 32) by a filling head (11, 33) with a defined filling pressure, the filling head (11, 33) being initially moved out of a rest position, which allows deliveryand insertion of a container (13, 32) into the filling station (10, 30), into a work position at the inserted container in which an end region (16) of the filling head seals the opening (14) of the container, the container (13, 32) is then filled, after the conclusion of the filling phase the filling head (11, 33) is again moved out of the work position into a rest position spaced apart from thecontainer (13, 32) and the container (11, 33) is then closed in the filling station (11, 33) by a closure cap (20) at least to such an extent that no more filling material can exit, and the container(11, 33) is then removed from the filling station (11, 33), characterised in that, before the lifting of the filling head (11, 33) from the work position into the rest position spaced apart from the container (13), in a pressure chamber (15) of the filling station (10, 30) surrounding the opening (14) of the container (13, 32) a positive pressure between the ambient pressure and the filling pressure is set, which is selected such that any foaming of the filling material located in the container (13, 32) is minimised to such an extent that no filling material exits from the container (13, 32) when the filling head (11, 33) is raised out of the work position after the filling operation.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 9 . Background technique [0002] So-called filling stations are used in the usual method for filling containers at higher production speeds. The filling station is arranged, for example, on a working wheel which cooperates with suitable devices for feeding empty containers and removing filled containers. Here, the empty containers are first inserted into the filling station. In a next step, the filling head arranged in the filling station is lowered into an operating position over the opening of the container and seals the opening. In this working position, a filling process takes place in which the filling product is introduced under pressure into the container via the filling head. After filling, the filling head is moved into a rest position spaced apart from the container opening. The containers can then be removed and transpo...

Problems solved by technology

A disadvantage is that the filling head moves laterally into the pressure chamber, which requires a relatively high construction effort
