<P>PROBLEM TO BE SOLVED: To provide a container cap that can easily break a flat seal part without increasing an inclination angle of the lower edge of a breaking cylinder. <P>SOLUTION: A container cap 1 includes an inner plug 3 provided with a cylinder part 31 and a cover part 33, a spout member 4 having a spout 41 and fitted onto the inner plug 3 to be depressable therefrom, and a spout cap 5 for closing the spout 41. A flat closing part 37 for sealing a flow path is breakably formed in the cylinder part 31, and a breaking cylinder 44 for breaking the flat closing part 37 along with the depression of the spout member 4 and opening the cylinder part 31 is formed in the spout member 4 communicating with the spout 41. The lower edge of the breaking cylinder 44 has a blade part 44a inclined obliquely and for breaking the flat closing part 37, and a non-blade part located at an uppermost end part, and also provided with a projecting blade part 44c formed to a part of the blade part 44a adjoined to the non-blade part and projecting downwardly. <P>COPYRIGHT: (C)2013,JPO&INPIT |
