<P>PROBLEM TO BE SOLVED: To realize a function with a simple and inexpensive structure to reduce pressure in a container in releasing blocking after completing the operation of automatically gripping a pusher while temporarily blocking a liquid feed line prior to the operation of pushing out liquid stored in the container with a liquid feed part at one end, by the pusher from the other end side. <P>SOLUTION: A simple and inexpensive grip control device is realized by providing an operation sequence of retreating the pusher after completing automatic grip of the pusher, and reducing the internal pressure of the container by retreating the gripped pusher before releasing blocking of the liquid feed line without adding a special mechanism. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
