Abstract
A sterile packaging assembly (100) for dispensing a liquid in drops comprises a main body (101) of plastic material, having a top portion (103) with an outside thread for receiving a screw cap (104), and containing a flow rate restriction system (105) for controlling drop formation. The flow rate restriction system is positioned substantially on the axis of the main body and is held in position by a constricted portion (106) of the top portion (103) of the main body. The invention is particularly applicable to sterile packaging of pharmaceutical substances such as eye drops.
