The present invention relates to a container assembly (1) comprising first and second containers (3, 5) and a closure element (19) common to the containers. Each container comprises an opening (7, 9) for permitting access to the interior thereof. The assembly (1) further comprises screw threads (21, 23) for selectively securing each container to the closure element independently of the other container so as to close the opening of the container. The closure element comprises an applicator (31, 33, 35, 37) associated with each container wherein each applicator extends through the opening of the associated container when said opening is closed by the closure element.
