Abstract
A dual compartmented container containing a medicament in one compartment and a diluent in the other with an actuating piercing element operable from outside the container. Mixing of the medicament in one compartment with the diluent in the other is accomplished by moving the piercing element inwardly into the container to pierce a primary diaphragm which seals one of the compartments to outside atmosphere as well as a secondary diaphragm which seals the compartments from each other. The piercing element is constructed and arranged to afford fluid communication between the compartments after it pierces both diaphragms. Intermixing of the contents of the container can thereby be made internally thereof.
