Abstract
Abstract A container for a hardenable multicomponent mass, used in anchoring a fastening member in a bore hole, has blind holes forming chambers. The chambers extend axially and are parallel to one another. The blind holes are arranged to receive individual components of the multicomponent mass. The container is formed of a destructable material, preferably a ceramic. When the container is broken or destroyed, the components mix to form the hardenable mass. The open ends of the blind holes are sealed by a cover after the components are filled into the chambers. The cover is located at an end face of the container.
