用于测试充装并密封后的容器的方法及设备
摘要：
本发明涉及一种测试方法，该方法包括将一批山形盖顶、涂覆了塑料的容纳液体的纸板盒(10)引入到压力腔室(2)内，封闭腔室(2)，向盒子(10)外部、腔室(2)的内部供应加压空气，其压力水平足以使空气渗透至少一个盒子的外部与该后者盒子的内部之间的潜在泄漏通路，藉此空气渗透到该后者盒子的内部，并且在一定时长之后，降低该压力水平，因此已经渗透到该后者盒子的内部的空气使该后者盒子的侧壁向外凸出。
摘要（英）：

A testing method comprising introducing into a pressure chamber (2) a batch of gable-top, plastics-coated paperboard cartons (10) containing a liquid, closing the chamber (2), supplying air under pressure to the interior of the chamber 2 exteriorly of the cartons (10) to a pressure level sufficient to cause the air to penetrate potential leakage paths between the outside of at least one of the cartons and the interior of the latter carton (s), whereby the air penetrates into the interior of the latter carton(s), and, after a period of time, reducing the pressure level, whereupon the air which has penetrated into the interior of the latter carton(s) causes outward bulging of the side walls of the latter carton (s).
