Abstract: A tamperproof security seal for a container which includes an outer cover member having a closed end wall with a plurality of through-holes therein. A locking member is adapted to be accommodated in the outer cover member with the locking member being formed of a sheet steel and having a plurality of rows of openings extending across a width of the locking member. The openings in each row are spaced from each other in a longitudinal direction of the locking member and are in axial alignment with each other and to the respective rows are in axial alignment with the respective openings of the end wall of the cover member. A drawstring is threaded through the openings in the locking member and the outer cover member so as to form a loop portion adapted to be placed over an opening of the container.

Abstract: A tamperproof security seal for a container and a method of manufacturing the same wherein a seal member is provided with a plurality of partition walls disposed in parallel to one another and in parallel to the end wall sections so as to define a plurality of channels extending across a width of the seal mamber. A plurality of holes are provided in each of the partition walls and in the end walls sections, with the holes extending through the partition walls and the end walls sections in a direction perpendicular to a longitudinal center axis of the respective channels. The holes in the partition walls and the end walls sections are disposed in alignment so as to enable a drawstring to be threaded therethrough. Upon a crimping of the seal member, the partition walls and the end walls sections are deformed so that the openings form individual anchoring or fixing points on the drawstring so as to prevent a withdraw of the drawstring from the seal member and prevent unauthorized access to the container.
