A device for separately packaging two components to be mixed together on first use, and for dispensing the resulting mixture, the device being of the type comprising two superposed containers suitable for communicating with each other via a passage and capable of rotating relative to each other about an axis of rotation without moving axially, a single shutter disposed in said passage to close it during separate storage of the components, one of the containers further including a guide mechanism for guiding displacement of the shutter in said passage and the other container including a drive mechanism for transforming relative rotation of the two containers into axial displacement of the shutter in the guide mechanism, thereby opening the passage. The shutter further includes a retaining mechanism suitable for limiting its displacement in the guide mechanism at the end of relative rotation of the containers.
