Patent ID: 8448800

Claim:
Method of assembling a container system for blood, body fluids, tissue parts, or tissue cultures, which container system has a closure device comprising a cap and a sealing device made from a pierceable, highly elastic and self-closing material which is inserted before said cap is screwed on, and a substantially cylindrical housing container enclosing an interior with an open end, whereby a cap casing of the cap extends around an open end face of the housing container by means of the cap having an open end region directed towards the housing container during the assembly process wherein the method comprises: inserting a sealing surface of the sealing device in the open region of the interior of the housing container; placing a thread arrangement with co-operating threads between the cap and the housing container; and creating a relative rotating or pivoting movement which is effected about a common longitudinal axis in order to assemble the closure device and the housing container, simultaneously assembling several closure devices with the housing containers to be joined to form the container system in a common assembly unit and prior to joining the components to be assembled the interiors of the housing containers are sealed off from the external atmosphere and are reduced to a pressure lower than the external ambient pressure and one of the components to be assembled is respectively supported on a thrust bearing of the assembly unit so as to be rotatable about its longitudinal axis for the joining operations, applying a pressing force (F) essentially axially along a longitudinal axis wherein the force is applied to at least one of the components to be assembled by the assembly unit; converting the essentially axial pressing force (f) intended to generate a relative rotating or pivoting movement about the common longitudinal axis by the co-operating threads which are configured at a pitch angle to convert said essentially axial pressing force into said rotating or pivoting movement; and engaging the threads of the thread arrangement with one another across the entire length of the screwing in path until the fully screwed in portion is reached during the relative rotating or pivoting movement.
