PROBLEM TO BE SOLVED: To smoothly pour out a liquid food and to prevent the liquid food from spurting out through a spout on opening of a package container. SOLUTION: A cap body is bonded by fusing to a specified part of a package container body 15 and comprises a fixing part 12 with a first through port 21 formed thereon, a hinge 13, and a spout part 14 having a second through port 22 and arranged so as to freely turn round the hinge 13 against the fixing part 12. The spout part 14 has a cutter 26 which comes into the first through port 21 as the spout part turns and ruptures a rupture part 16 formed at the package container body 15. As the spout part 14 is turned to open the package container 10, the cutter 26 comes into the first through port 21. With the spout part 14 pushed down at this time, the cutter 26 is pushed down likewise and the rupture part 16 is ruptured.
