The closure includes an inner closure cap having a cap part which overlies the container opening and an annular side skirt portion which is engaged around the exterior of the container neck portion, and which includes an inwardly extending cap bead engaged in a cap receiving recess of the container. A hollow central part extends through this cap part which goes above the exterior face and below the interior face and it defines an opening therethrough. An outer cover has an internally threaded outer cover skirt part which threadably engages with the externally threaded neck portion of the container. In addition the outer cover has a top cap ledge wall which overlies the rim and is engageable over the top cap part and it also has a central raised cap part extending to a level above the ledge wall and an overlying the hollow cylindrical part. A stopper projection is defined on the raised cap part and it is engageable into the hollow cylindrical part, preferably with a wedging fit. A stopper is captured within the cylindrical part and it includes a lower flat disc portion which forms a stop for a movable cylindrical retaining ring.
