具体实施方式
关于图1到6,描述了根据本发明的一个实施例的容器1。所展示的容器1包括柔性膜2,所述柔性膜被布置成限定内部空间3和限定轴向的贯穿开口,所述贯穿开口允许内部空间3与膜的外部连通。所述容器还包括密封连接装置,所述密封连接装置被布置成允许柔性膜2连接到无菌箱的互补连接装置。所述连接是以确保所述容器1的内部空间3与箱的内部空间之间无菌连通的方式进行的。
连接装置包括法兰,柔性膜附接在所述法兰上,所述法兰界定柔性膜的贯穿开口。连接装置进一步包括可移除的门7,所述可移除的门附接到法兰,以便使贯穿开口闭合。有利地,法兰和门7通过分别由法兰和门支承的凹口和凸耳彼此连接。
在所展示的实例中,法兰由两个彼此不同的部件构成,第一部件形成所谓的外部套筒,并且第二部件形成所谓的内部套筒,柔性膜在这两个部件之间延伸。内部套筒6包括邻近支承凹部的带凹口区域64,所述带凹口区域被布置成与设置在外部套筒5的内面50上的互补凹口54配合。根据图4所示的有利构型,外部套筒5包括下裙部10,所述下裙部包括从所述套筒的下端边缘延伸的纵向槽11。这些纵向槽11有利地均匀分布在所述套筒的外围之上。所述纵向槽因此界定弹性接片12,当外部套筒5安装在内部套筒6上时,所述弹性接片能够在内部套筒6的整个外围之上施加均匀夹紧力。弹性接片12包括分别与如下所述的夹紧构件以及内部套筒6实现相互关联的构件。在所展示的实例中,分别与夹紧构件和内部套筒6实现相互关联的构件由螺纹53和凹口54组成。夹紧构件呈外部夹紧环9的形式,所述外部夹紧环包括内螺纹90,所述内螺纹的形状与设置在外部套筒5的外面52上的螺纹53互补。夹紧构件被布置成抓握外部套筒5和内部套筒6的之间插置有柔性膜2的部分。
容器1进一步包括环形密封件8,所述环形密封件容纳在形成于外部套筒5的内面50和内部套筒6的外面60上的外围凹槽中。所述环形密封件限定法兰/袋密封件。如图3所示,柔性膜2保持抓握在环形密封件8与内部套筒6之间。为了提高柔性膜2在构成法兰的这两个套筒之间的保持力,内部套筒6包括设置有支承凹部的外面,所述支承凹部与外部套筒5的外围凹槽相对。因此,当外部套筒5夹紧在内部套筒6上时,环形密封件8在支承凹部处挤压柔性膜2,从而确保柔性膜2的改进接合。
容器1进一步包括由法兰支承的环形密封件13。所述环形密封件限定门/法兰密封件。当门处于封闭贯穿开口的位置时,环形密封件13容纳在由外部套筒5、内部套筒6和门7界定的空间中。有利地,环形密封件13具有与其所容纳的区域相匹配的形状的横截面。在所展示的实施例中,环形密封件13具有L形截面。
根据本发明,所述容器包括连接装置的保护盖20,所述保护盖强力夹持到法兰5、6上。在所展示的实施例中,保护盖20包括与容器的正面相对放置的覆盖部分21,在所述覆盖部分的外围处,两个接片22、23在夹紧环9的方向上延伸。“正面”意指容器的关于其与箱的连接的面。换言之,正面是容器的与箱相对以将所述容器连接到箱的面。
每个接片22、23在其自由端处设置有肩部220、230,所述肩部由在所示实例中在覆盖部分21的相对侧上径向延伸的材料凸起形成。接片22、23有利地基本上平行于轴向轴线在夹紧环9的方向上延伸,并且分别穿过在所述夹紧环9中形成的相关联的孔92、93,使得肩部220、230位于夹紧环9下方。因此,如图2所示,保护盖20的夹持包含将接片22、23的肩部220、230接合在限定孔的夹紧环9的后支承边沿上。
在所展示的实施例中,保护盖20包括在直径上彼此相对定位的两个夹持接片22、23。这是一个示例实施例;接片的数量和分布可以根据容器开口的尺寸而变化。
保护盖20进一步包括布置在保护盖20与连接装置之间的接触压力构件,以便在轴向方向上对第一密封件13施加与夹持力成比例的接触压力。在所展示的实例中,压力构件由覆盖部分21的内面210上的环形凸台24形成。因此,环形凸台24被布置成在保护盖20放置在容器上时面向门/法兰密封件13放置。在此实施例中,压力构件与保护盖20整体形成。根据变体实施例,压力构件可以由如密封件等布置在保护盖20与门/法兰密封件13之间的附加部分组成。在所描述的实施例中,环形凸台是连续的。根据变体实施例,可以设置形成不同压力点的不连续凸台。
有利地,接片22、23被布置成使得可以通过所述接片的变形来移除保护盖20。为此,所述接片各自具有与肩部220、230相对布置的V形凹口。图7和7a示出了如此布置的接片的细部视图,仅示出了接片22和其凹口221。根据变体实施例,还可以规定在凹口处对接片22、23进行刻痕。因此,取决于所使用的材料,通过凹口获得的脆性允许接片22、23局部变形或接片在凹口处断裂。
由于连接装置的组成元件的布置,连接装置是通过简单地将所述元件彼此夹持来组装的。为了制造容器1,柔性膜的位于贯穿开口一侧的部分将被布置成放置在外部套筒5和内部套筒6之间。通过将环9夹紧在内部套筒6上,从而使接片12抓握在内部套筒6上,夹紧将会有效。柔性膜2可以通过拧松夹紧环9并从内部套筒6上松开外部套筒5来拆卸。然而,柔性膜的拆卸只能在移除保护盖20之后进行。
柔性膜2和连接装置有利地由抑菌材料制成。密封件8和13由硅酮材料或使剩磁现象最小化的其它材料制成。还可以规定密封件由抑菌材料制成。
在刚才描述的实施例中,接触压力构件被布置成对密封件施加接触压力。根据图8所展示的变体实施例,可以规定将接触压力构件布置成对门7施加接触压力。如前所述,压力构件可以由连续或不连续的环形凸台24形成,所述凸台设置在覆盖部分21的内面210处,并且被布置成在保护盖20放置在容器上时与门7相对放置。压力构件还可以由被布置在保护盖20与门7之间的附加部分(密封件或其它)支承。在所描述的实施例中,环形凸台是连续的。
前文通过举例描述了本发明。应当理解,在不脱离本发明的范围的情况下,本领域技术人员能够产生本发明的各种变体实施例。
