  • Process and apparatus for filling and sealing a container, and a container made thereby
    Patent number: 4905450
    Abstract: To minimize the air volume present in a container following heat sealing, the dimensions of the flowthrough passage of the filling connection are decreased in a first heat sealing operation. Then, the container is elastically deformed by a punch to such an extent that the liquid content level rises up inside the filling connection. Finally, in a second heat sealing operation, the end segment of the now funnel-shaped flowthrough passage of the filling connection is heat sealed such that it is totally sealed without pores.
