<P>PROBLEM TO BE SOLVED: To check leakage of a bag-like container that does not include any mouth member. <P>SOLUTION: A leakage check system comprises a nozzle 10 which is inserted into an opening of a bag-like container 100, and a pair of seal members 20. The pair of seal members 20 seal a gap between the nozzle 10 and the bag-like container 100 by pressing an opening edge 103a of the bag-like container 100 in the state where the nozzle 10 is inserted into the opening 103 of the bag-like container 100. Further, the leakage check system comprises a compressed air supply path 1 connected to the nozzle 10, a pressure sensor 5 and a differential pressure sensor 7 connected to the compressed air supply path 1. In such a sealed state, compressed gas is supplied from the compressed air supply path 1 through the nozzle 10 to the bag-like container 100 and then, fluctuation in pressure of a closed system of the compressed air supply path 1 including the bag-like container 100 is detected by the pressure sensor 5 and the differential pressure sensor 7, thereby determining the presence/absence of leakage of the bag-like container 100. <P>COPYRIGHT: (C)2013,JPO&INPIT |
