Abstract

An apparatus for combining liquid or solid components stored in containers includes a cylindrical hollow body for receiving end closures of the containers and at least one cannula for penetrating the end closures. The cannula is mounted in a cannula holder movable in the hollow body, and retainer bridges connect the cannula holder to an inner wall surface of the hollow body. The retainer bridges fracture after the cannula penetrates the end closure in the first container so that the cannula moves toward the second container to penetrate the closure in the second container. Also disclosed is a system including the apparatus, two containers, and outer packaging enclosing the containers and the hollow body.
