seen and device for forpacka products in vesentligen oxygen free atmosfer

摘要

A method and apparatus are provided for packing products in bottom closed containers of cardboard, plastic, glass or the like, without vacuum suction or compression and in a substantially oxygen free atmosphere. A bottom closed container is mounted in a substantially air tight condition on a holder funnel and thereafter a piston in sealed engagement with the inner sides of the container is forced down through the container to the bottom thereof so that the air which is present in the container is forced up to the upper side of the piston. The piston is then withdrawn from the container to thereby exhaust the air which is present above the piston. A protective gas is introduced simultaneously with the withdrawal of the piston at a location underneath the piston and without subjecting the interior of the container to the influence of air as the container is filled with the product to be packed. The filled container is transfered to a station sealing and closing.
