A mixing container and an adapter to interconnect the mixing container to a second container to permit intermixing of the contents of the containers. The mixing container has a neck with a plurality of raised circumferential ribs thereon. The adapter has a central cylindrical sleeve. A first end of the sleeve is surrounded by a cylindrical skirt. The interior surface of the first end of the sleeve has a plurality of circumferential grooves which enable the adapter to engage the ribs on the neck of the mixing container. The interior surface of the cylindrical skirt has a screw thread to enable the adapter to engage a conventional threaded container neck. The opposite, or second, end of the sleeve has a cutting sleeve therein, concentric with the sleeve. The cutting sleeve is adapted to pierce a seal on the mixing container. The second end of the sleeve frictionally engages the raised circumferential ribs on the mixing container during the mixing operation. The cutting sleeve and the central sleeve define a passage through the adapter to permit intermixing of the contents of the containers. In a second embodiment of the invention, the mixing container and the adapter are keyed so that the seal on the mixing container can be broken only when the mixing container is at a particular angular orientation with respect to the adapter to avoid unintentionally breaking the seal.
