    • The invention relates to a closure device and a method for performing an assay of a sample using the closure device. The closure device, mountable on the mouth of a test vessel, comprises a body part (1) with an axially passing cylindrical bore. The bore is covered at one end with an openable lid (7). The closure device further includes a plunger (3), slidably mounted in the bore for the formation of a sealed reagent storage chamber (9) in the space remaining between the closed lid and the plunger. The inner wall of the bore (2) is provided with at least one groove (4), whose depth is so deep as not to be within the reach of the outer diameter of the plunger (3). The groove extends from exterior end of the bore, over such a length as to maintain a gas flow communication between said reagent storage chamber (9) and the exterior end of the cylindrical bore when the plunger (3) is in a partially inserted position. In the assay method according to the invention, the reagent is added from the closure into the test vessel containing the sample.
    • 本发明涉及一种闭合装置和使用封闭装置进行样品测定的方法。 可安装在测试容器的口部上的封闭装置包括具有轴向通过的圆柱形孔的主体部分(1)。 孔的一端用可打开的盖(7)覆盖。 闭合装置还包括可滑动地安装在孔中的柱塞(3),用于在保持在闭合盖和柱塞之间的空间中形成密封的试剂储存室(9)。 孔(2)的内壁设置有至少一个凹槽(4),其深度非常深,不会在柱塞(3)的外径范围内。 所述槽从所述孔的外端延伸超过所述长度,以便当所述柱塞(3)处于部分插入位置时,保持所述试剂储存室(9)与所述圆柱形孔的外端之间的气流连通。 在根据本发明的测定方法中,将试剂从封闭物加入到含有样品的测试容器中。
