MIXING FLASK CONTACTING TWO ISOLATED CONSTITUENTS BEFORE THEY ARE DRAWN AND INJECTED INTO A SYRINGE

摘要

The invention concerns a mixing flask for mixing two isolated constituents before they are drawn, comprising two tiered compartments one of which consists of the flask (1) itself, and the other is limited by joint (4) with a profile shaped like a base cup mobile inside the flask neck (2), of smaller cross-section than the main body, for contacting the two compartments, by the action of a plug capable of being pierced (10) mobile in said neck countering the force of an elastic crimping sleeve (14). The invention is useful for mixing solvent and lyophilizate before it is injected with a syringe.
