Abstract
一种贴附于被测物柔性壁上的改良的泄漏测试装置具有一箔(4)，所述箔(4)在所述被测物的外侧限定了一空腔(1)，并具有一泄漏点(2)，所述箔(4)用来贴附于被测物上。
Description
技术领域
本发明涉及一种贴附于被测物外侧上的泄漏测试装置。
背景技术
测试泄漏用于检测和校验用于检测被测物的气密性的泄漏测试系统。典型地，被测物为食品包装、药品包装或医学领域的无菌物体的包装。泄漏测试用于检测可能引起所包装的产品损坏的包装的泄漏。被检测气密性的物体具有形成产品的包装的薄壁。所述泄漏测试通过使用泄漏测试系统以自动方式进行。考虑到即使是被测物中很小的泄漏也会引起所包装的产品的损坏，所述泄漏测试系统必须能够可靠地检测到小的泄漏。所述泄漏测试系统须定期检测，必要时进行校准。为了达到这一目的，所述测试泄漏用于被测物的外侧进行。
由欧洲专利EP 1 119 755 B1可知，在被测物的壁上设置一可重复密封的测试气体可透过的贴片式泄漏。所述贴片式泄漏具有一圆周粘着边缘，通过所述粘着边缘贴附在所述被测物的外侧。所述贴片式泄漏封住所述被测物上特制的孔，形成一限定的泄漏点。在所述被测物的外侧，从所述被测物的内部通过所述贴片式泄漏泄漏到外侧的气体可被检测到。
发明内容
本发明的目的在于提供一种可在生产线上对包装进行无损检测的改良的测试泄漏。
本发明的泄漏测试装置由权利要求1的特征定义。
所述泄漏测试装置具有一箔和粘膜。所述泄漏测试装置通过所述粘膜贴附于被测物的外侧。在所述箔和粘膜之间形成一空腔。在空腔区域，所述箔上具有一限定的泄漏点。从泄漏点泄漏并被一泄漏测试系统检测到的测试气体包含在所述空腔内。这样，所述泄漏检测装置形成一测试泄漏，并且具有不会由于安装测试泄漏而导致被测物被损坏的优点。所述测试泄漏仅贴附于所述被测物的外侧，并包含一定量的测试气体，所述测试气体以一预定的泄漏速率通过所述泄漏点泄漏。当用于检测和校准泄漏测试系统时，本发明的所述泄漏测试装置可以贴附于用所述泄漏测试系统测试的被测物上，而不损害所述被测物。然后，所述被测物被用于所述泄漏测试系统，在所述泄漏测试装置的帮助下进行检测与校准泄漏测试系统。
在这一点上，尤其有利的是所述粘膜和箔由柔性的形状可变的材料、尤其是被测物的包装材料或至少与被测物的包装材料相似的材料制成。这样的好处在于待检测和校准的泄漏测试系统与常用尺寸、形状和种类的被测物设置在一起。
优选地，一加强元件设置在所述空腔内所述箔和粘膜之间，所述加强元件例如为圆环形式或开孔的泡沫材料。所述加强元件用于将所述箔和粘膜分开，并为所述测试气体提供一稳定的空腔。当使用圆环时，所述泄漏点应设置在所述圆环的开口的区域，如圆环的中心纵轴上或与圆环同心。当所述加强元件为开孔的泡沫材料时，所述开孔的泡沫材料容纳测试气体并同时提高稳定性。作为开孔的泡沫材料的替代，可使用任何能够使空腔达到所需稳定的储存空气或测试气体的材料。所述空腔的体积可小至刚好足够一次测试，或可用于多次测试。
通过所述粘膜，所述泄漏测试装置贴附于所述被测物的外侧。有利的是，所述粘膜和箔由柔性材料制成。所述泄漏测试装置可以泥膏形式贴附。可选地，所述泄漏测试装置也可为刚性的。测试后，所述泄漏测试装置从所述被测物上取下，而不损坏所述被测物。
所述泄漏测试装置的泄漏点可为箔上的一直径小于1mm的小孔。可选地，所述泄漏点可为一最大1mm的可变直径的可调节的孔，或者为透气的箔。
附图说明
下面结合附图对本发明的实施例进行详细说明。
图1为泄漏测试装置的俯视图；
图2为泄漏测试装置沿图1线II-II的剖面图。
具体实施方式
所述泄漏测试装置包括一箔4、一粘膜3以及一加强元件5，从而形成一测试泄漏。所述箔4和粘膜3为外径相等的圆形。所述箔4位于所述粘膜3之上，并固定连接到所述粘膜3的边缘部分。在与所述箔4的中心同心且环绕所述粘膜3的区域，所述箔4未连接到所述粘膜3，从而与所述粘膜3形成一空腔1。在所述箔4的中心设有一泄漏点2，其为直径小于1mm的小孔。所述泄漏点2提供了通向所述空腔1的通道，使得所述空腔1内的测试气体能够通过所述泄漏点2泄漏出，并能够被泄漏测试系统检测到。在所述空腔1的外边缘区域内，所述加强元件5以一将所述箔4和所述粘膜3分开的圆环的形式置于其中，从而建立稳定的空腔1。这降低了所述箔4贴附于所述粘膜3从而改变所述测试气体通过所述泄漏点2的流出特性的风险。
所述粘膜3在与所述箔4相对的一侧具有一粘着层，其为胶带或泥膏类型。使用该粘着层，所述测试泄漏可以贴附在被测物的外侧而不对其造成损伤。
