ABSTRACT:
A device for containing a substance and adapted to release the substance into a vial comprising a container adapted to be supported on the vial having a cylindrical space adapted to contain the substance with a closing bottom connected thereto for closing the cylindrical space and retaining the substance. A piercing piston is slidably mounted within the cylindrical space of the container and provided with a lower piercing point for piercing through a weakness defined between the container and its closing bottom. A vertically and circumferentially extending groove is defined in the container within the circumferential space and a projection is defined on the piercing piston which in engaged within the groove. The groove and projection thus restricts the sliding motion of the piercing piston to permit the piercing piston to be slid downwardly to pierce through the weakness defined between the container and its closing bottom only when the piercing piston is at a selected predetermined rotational position so that its piercing point is positioned over the weakness.
