ABSTRACT:
A sealing cap, particularly for sealing against a non-circular sealing surface about an opening of a container (such as a wide roller type roll-on container), wherein the sealing gap includes a closure, a sealing member in the form of a non-circular gasket arranged within the closure for sealing against the non-circular sealing surface of the container, and an alignment disk in the closure for aligning the sealing gasket with the non-circular sealing surface during relative rotation of the sealing cap and container. The alignment disk and sealing gasket are rotatably supported within the closure. The alignment disk includes a non-cylindrical well for receiving the non-circular sealing surface of the container and a pair of opposed inclined surfaces for aligning the sealing gasket with the non-circular sealing surface during relative rotation of the container with the sealing cap. The alignment disc can be used in other appliccations than in a sealing cap, e.g., for aligning coupling surfaces of two members to be coupled, with one coupling surface being exposed in the non-cylindrical well and the other coupling surface being introduced into the alignment disc to be aligned with the first coupling surface.
