A stopper assembly adapted for use in connecting a container with one component therein to a piston and cylinder type syringe assembly with a liquid component therein, with the components initially separated by the stopper assembly prior to permissive mixing of the components in the container upon manipulation of the stopper assembly; and comprising a centrally bored first stopper adapted for insertion in the container opening and receiving the syringe access fitting in the bore thereof; and a second stopper passing into the adjacent end of the said bore for sealing the bore and the opening to the syringe fitting whereby to maintain the components separated when the container and syringe assembly are mounted to the stopper assembly; said second stopper being releasable from its connection with the first stopper to drop into the container when the syringe piston is urged inwardly whereby to permit the component in the syringe to access to the component in the container for mixing therein.
