PCT No. PCT/DK92/00329 Sec. 371 Date May 2, 1994 Sec. 102(e) Date May 2, 1994 PCT Filed Nov. 10, 1992 PCT Pub. No. WO93/09753 PCT Pub. Date May 27, 1993.A container for receiving and separating blood plasma into its ingredients comprises two sealingly coupled sections (1 and 2). One container section (2) and the adjacent portion of the other container section are made of solid material, and the two container sections are screwed together. The container sections (1 and 2) comprise their respective chambers (29 and 30) for receiving their respective fluid ingredients, and these chambers are interconnected through a connecting channel (31) through the abutting portions, at which the container sections (1 and 2) are screwed together. A valve seat (21, 27) is shaped at each end of the connecting channel (31) for each valve member (22, 16) for a sealing closing of the chambers (29, 30) in the separated state of the container sections (1, 2). The valve members (22, 16) comprise mutually abutting projections (23, 12) ensuring a distance between the valve members (22, 16) exceeding the distance between the associated valve seats (27, 21) in the coupled state of the container sections (1, 2), but being smaller than the distance between the associated valve seats (27, 21) in a position during a separating movement of the container sections (1, 2). Furthermore, retaining means (15, 16) are provided for ensuring that the valve members (22, 19) do not engage the valve seats (27, 21) in the coupled state of the container sections (1, 2).
