PROBLEM TO BE SOLVED: To provide a dispensing cap with a weakened part in which a force required for breakage in unplugging is reduced and the inside of a container is reliably sealed until the container is opened.SOLUTION: A dispensing cap comprises a cap substrate A mounted on a container body, and an upper lid B. A partition wall 7 for sealing the inside of the container body is continuously arranged in the inside of a dispensing tube 6 provided in the cap substrate. A stopper part 17 for forming a part to be opened serving as a dispensing port is defined by a breakable thin-walled weakened part 19 formed by a cutting groove 18 in the partition wall. A pull ring 22 is continuously arranged on the upper surface of the stopper part through a strut 21. The cutting groove is formed in a predetermined range in which an upper groove 25 engraved from an upper part, in addition to a lower groove 26 engraved from a lower part, has at least a portion closest to the strut 21 as the vicinity of the center. An angle α of the corner of an inner circumferential side of the upper groove and an angle &bgr; of the corner of an outer circumference side of the lower groove are both an acute angle. |
