Abstract: A cosmetic applicator, includes a container, having an opening provided with an external thread, and a cap assembly for capping the container opening. The cap assembly includes an internal thread engageable with the external thread, a shaft extending from the opening to the interior of the container, and a cosmetic applicating member disposed at an end of the shaft. The cap assembly further includes an outer cylindrical portion of which the inner surface is provided with the internal thread engageable with the external thread of the opening of the container and a mechanism for allowing the applicating member to be moved downwardly in the container to access cosmetic after the cap assembly has been unscrewed from the container. The mechanism includes an inner plug disposed around the shaft so that the shaft is slidable along the shaft direction but not rotatable relative to the cap assembly. The inner plug contains a spring mechanism.
