The invention relates to a container cover, including a main cover, a blind hole in the middle of the main cover, a puncture film at the bottom of the blind hole, and a vice cover, which comprises a cover body and a blind hole matching the cover, so that the cover can be detachably connected to the main cover and seal blind holes. The main cover is inserted into the container port and seals the container through the matching and sealing of the container with the auxiliary cover. When the reagent in the container is used, the auxiliary cover is pulled out from the blind hole and the needle is drawn through the puncture membrane at the bottom of the blind hole. The diameter of the sample needle is small and the reagent is not volatile from the needle mouth of the sample needle. Go out; after the sampling needle is left, because the tension of the bottom of the blind hole is springback, the sampling needle is narrowed through the produced needle mouth and prevents the reagent from volatilizing; the sealing property is good, the reagents are dismantled and the reagents are easily disassembled through the combination of the main cover and the auxiliary cover to seal the container's container, and the reagents are easily disassembled and the reagents are not volatile through the puncture film. The loss caused by volatilization is reduced.

技术介绍
免疫分析中,根据具体分析项目的不同,试剂通常包括多个组分,如常见的2-5个组分,包括磁微粒试剂、标记试剂、稀释液、预处理液等试剂组分。非均相免疫分析中通常用到的磁微粒试剂组分又称为固相试剂,要求固相试剂在仪器取样前处于均匀悬浮状态。一般情况下,同一个项目的多个试剂组分通常灌装和储存在若干独立的瓶体或腔体中,瓶体和支撑瓶体的瓶架或者一体成型的腔体组成一个项目的试剂盒,试剂盒使用时,将其固定于试剂仓以供分析过程中取用。传统的容器盖的设计,存在使用不方便、密封困难、试剂盒漏液(尤其是运输过程中漏液)等问题。
技术实现思路
基于此,有必要针对上述问题,提供一种容器盖,该容器盖具有密封性良好、便于拆卸、不易漏液的特点,且便于通过所述容器盖向容器内取用试剂。一种容器盖,包括:主盖,主盖的中部设有盲孔,盲孔的底部设有穿刺膜;及副盖,副盖包括盖身,盖身与盲孔匹配,以使盖身可拆卸地连接主盖并封盖盲孔。上述容器盖,使用时,主盖塞入容器的容器口,并通过与副盖的配合密封容器口,从而密封容器;当需要取用容器内的试剂时,将副盖从盲孔内拔出,然后加样针穿过盲孔底部吸取试剂,由于盲孔的底部为穿刺膜,采样针可穿透穿刺膜伸入容器内,而采样针的直径较小,试剂不易从采样针的针口处挥发出去;采样针离开后,由于盲孔底部的张力回弹,采样针穿过产生的针口缩小,防止了试剂挥发;通过主盖与副盖的配合封紧容器的容器口,密封性良好,不会漏液,且便于拆卸取用试剂,通过盲孔底部吸取试剂,试剂不易挥发,很好地保持了试剂的浓度,并减少了因挥发而产生的 ...
