PURPOSE:To easily eject contents with a single hand from a liquid paper package which is mounted in an inversely standing state with its outlet port facing downward by mounting an elastic body between a bottom plate having a flow hole attached to an inner wall of a cock body and a locking plate larger than the outlet port of a core rod protruding from the outlet port. CONSTITUTION:Normally, contents flow into a cock body 3 little by little through a flow hole 11, wherein since a locking plate 15 of a core rod 14 is in tight contact with a summit 6 of the cock body 3 due to repulsive force of a coil spring 13 and an outlet port 8 is closed, the contents may not be ejected. At the time of ejection, if a hand presses the core rod 14 at the tip of the core rod 14 against the repulsive force of the coil spring 13, a gap is generated between the locking plate 15 and the cock body 3, so that the contents staying in the cock body 3 are ejected from the outlet port 8. When the hand comes off the core rod 14, the core rod 14 is pressed back by restoring force of the coil spring 13, the locking piece 15 comes into contact with the summit 6 for closing the outlet port 8. |
