<p>PROBLEM TO BE SOLVED: To provide a pinch cock that can be held in an opening position with a pushing operation. SOLUTION: The pinch cock has a fixed plate 3 annexed to an outer surface of a spout pipe 1 connectable to a discharge port of a container, formed at one end into a first clamping portion 4 adjacent to a flexible tube 2 dependent from a spout pipe tip end, and formed at the other end into an engaging jaw 5; a movable plate 7 turnably mounted on the spout pipe 1, formed at one end into a second clamping portion 9 capable of abutting the first clamping portion 4, and formed at the other end into a pressing operation end capable of engaging the engaging jaw 5; and a spring 10 for urging the movable plate in a direction to abut the second clamping portion 9 against the first clamping portion 4. The movable plate has a closing position to shut off a flow as the second clamping portion 9 abuts the first clamping portion 4 to clamp the flexible tube 2, and an opening position to open the flexible tube 2 as the operation end is pushed to separate the second clamping portion 9 from the first clamping portion 4.</p> |
