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) far 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).

Un ingrédient pour recevoir le plasma sanguin et séparer ses ingrédients comprend deux sections (1 et 2) reliées hermétiquement. Une section du récipient (2) et la partie adjacente de l'autre section du récipient sont constituées d'un matériau solide, et les deux sections du récipient sont vissées ensemble. Les sections (1 et 2) du récipient comportent leurs chambres respectives (29 et 30) conçues pour recevoir les ingrédients respectifs du fluide; ces chambres sont reliées par un canal de liaison (31) à travers les parties en contact, à l'endroit où les sections (1 et 2) du récipient sont vissées ensemble. Un siège de clapet (21, 27) est formé à chaque extrémité du canal de liaison (31) pour chaque élément de clapet (22, 16) de manière à fermer hermétiquement les chambres (29, 30) et isoler l'une de l'autre les sections (1 et 2) du récipient. Les éléments de clapet (22, 16) comportent des zones (23, 12) de contact mutuel, permettant d'assurer que la distance entre les éléments de clapets (22, 16) soit supérieure à la distance entre les sièges de clapet (27, 21) correspondants lorsque les sections (1 et 2) sont en communication, mais qu'elle soit inférieure à la distance entre les sièges de clapet (27, 21) correspondants lors du mouvement de séparation des sections (1 et 2) du récipient. De plus, des dispositifs de retenue (15, 16) sont prévus pour assurer que les éléments de clapet (22, 19) ne viennent pas en contact avec les sièges de clapet (27, 21) lorsque les sections (1 et 2) du récipient sont en communication.
