ABSTRACT:
A blow molding method manufactures a sealed container and fills the container with a substance. The container body is connected to a head or top. A part of the head can be detached for opening of the container. A segment of an extruded tube is mounted in a blow mold having an axially movable mold base. The diameter of the extruded tube is slightly greater than the diameter of the head or top. Following the closing of the tube end forming the bottom of the container, air is blown into the tube and simultaneously the mold base is moved toward the top jaws of the blow mold forming the head. After filling of the container and possibly mounting of an insert body into the top segment of the tube forming the container head or top, the mold base is moved still further in the direction of the top jaws, until the container is free of air. Then, the head is formed and is sealed securely with the outer surface of the insert body.
