The application relates to a collection assembly (1), in particular for blood samples, comprising a sample container (2) and a closure device (3) which has a closure cap (22) and a pierceable septum (26) held on the closure cap. At its open end (4) delimited by an end face (11), the sample container has a flange (13) and an annular skirt (15), the flange projecting radially beyond a side wall (7). The annular skirt (15) extends axially from a flange end (14) to a closed end (5) of the sample container (2). The sample container (2), the flange (13) and the annular skirt form a one-piece component. Between an outer surface (9) of the side wall (7) and an inner annular skirt surface (16) facing toward this outer surface, there is an approximately tubular free space (17) which is delimited in the axial direction in the region of the open end (4) by the flange (13).本發明係有關一種收集組件(1)，特別用於血樣，包括樣本容器(2)及封閉裝置(3)，該封閉裝置具有封蓋(22)及固定於該封蓋(22)上之可刺穿隔片(26)。該樣本容器(2)在其與端面(11)交界之開口端(4)具有一徑向凸出於側壁(7)之凸緣(13)及一環簾(15)。該環簾(15)自凸緣末端(14)出發沿軸向朝該樣本容器(2)之封閉端(5)延伸。該樣本容器(2)、該凸緣(13)及該環簾(15)形成一體式部件。在該側壁(7)之外表面(9)與該環簾(15)靠近該側壁之內環簾面(16)間形成大體呈管狀之自由空間(17)，該自由空間沿軸向在該開口端(4)區域被該凸緣(13)限定。
