Abstract:
A holding device for body fluid, tissue parts and tissue culture media, comprising(a) a cylindrical holding container having a container wall with an inner surface and an outer surface, the holding container having a first and a second open end face, the inner container wall surface defining an inner space, the first open end face having a diameter which is at least equal to the diameter of the inner space, and the second open end face having a conical sealing surface tapering inwardly in the direction of the inner space,(b) a first closure device for closing the first open end face, the first closure device including(1) a cap surrounding the outer container wall surface,(2) two extensions projecting inwardly from a cylindrical inner surface towards a longitudinally extending medial axis of the holding container, the extensions being arranged in planes extending perpendicularly to the medial axis and being spaced apart in the direction of the medial axis, and(3) a penetrable cylindrical seal device mounted in the cap, a first portion of the seal device forming a sealing surface with the inner container wall surface, and an adjacent flange-shaped seal device portion projecting radially outwardly and being held between the two extensions, one of the extensions projecting inwardly between the first and adjacent portions of the cap, and(c) a second closure device for closing the second open end face, the second closure device including(1) a solid conical seal body having a sealing surface conforming to the conical sealing surface of the second open end face, and an outer end face of a larger diameter than that of an inner end face facing the inner space,(2) a retaining member abutting the outer end face, and(3) coupling means on the outer container wall surface, the retaining member having means for engaging the coupling means and for holding the seal body in a sealing position in the second open end face.
