Container closure with overlying needle penetrable and thermally resealable portion and underlying portion compatible with fat containing liquid product, and related method

摘要

The present invention consists of a container and closure assembly for a fat containing liquid product. The closure assembly further comprises a stopper, sealing member, and securing member. The container and closure assembly are made of materials which do not leach a significant amount of a leachable substance into the liquid product. Also disclosed is a method for filling the containers, comprising the steps of advancing a needle filling assembly through the closure assembly, filling the container, removing the needle assembly, and thermally sealing the needle aperture. These steps may also be preceded by the step of sterilizing the outside of the container with a liquid, then blowing away the liquid with a sterile gas before the container reaches the filling assembly.
