PURPOSE: To provide a pouring outlet for carton which is simple to open and capable of resealing.

CONSTITUTION: A sealing member 24 is formed integral with an upper edge of a cyrindrical part 22 in a pouring part body 2 through a thin-walled part 23, and a pull-ring 25 substantially of the same diameter of a mouth as that of the cylindrical part 22 is provided at an upper part of the sealing member 24. If a cap 3 is put off and the pull-ring 25 is pulled up, the sealing member 24 comes apart at the thin-walled part 23, whereby an unsealing can be achieved. In this case, as the pull-ring 25 which is exposed on an upper part of the pouring part body 2 and has a large diameter is pulled up, the unsealing can be achieved easily. After unsealing, the cap 3 can be put on to seal again just as a prior art cap can be done.
