Abstract

The invention relates to an insert and a vial for the infusion of a liquid. The vial comprises a hollow body, a grasp portion and a head. The head comprises a delivery opening defining an axis X; a septum for closing the opening; and at least one circumferential push surface next to the head and firmly connected to the grasp portion. The insert is suitable to deliver the liquid and to receive the vial along axis X. The insert comprises a main body with lower ducts, an inner part and a piercing spike. The inner part defines a seat for the vial head, and comprises one slit for engaging the circumferential push surface. The spike is suitable to pierce the vial septum and defines upper ducts. The inner part is able to rotate inside the main body between a fluidly open configuration and a fluidly closed configuration.
