  • Patent number: 4516998
    Abstract: The present invention relates to a new method of making tubular vials and ampules from glass tubing. The method according to this invention is essentially characterized in that the glass tubing used is closed at both ends and has a dot-shaped opening close to one of the sealed ends. The opening can be sealed by a film to prevent impurities from entering the glass tubing. Throughout the operational process in the production of vials and ampules, a slight excess pressure exists in the glass tubing by applying heat, which further prevents impurities from entering the glass tubing.

  • Patent number: 4250687
    Abstract: Packaging of tubes or rods is disclosed. The tubes or rods consist of a brittle material such as glass or ceramics. In a method for packaging, the tubes or rods are arranged in one package in the tightest possible packaging form. This package is encased by a hood preferably consisting of a film of synthetic material which is fitted over the package under stress and which thereby locks the tubes or rods in position. A plurality of such packages can be stacked on a conventional pallet and can be encased by an additional hood locking this stack in position.
