PROBLEM TO BE SOLVED: To obtain a safety cap of which the opening operation is easy and which has no danger of being opened by a little child. SOLUTION: This safety cap is a cap having a double structure comprising an inner cap 3 coupled with thread to an outer circumference of a mouth of a container main body of a tube container and an outer cap 5 covered on an outer circumference of the inner cap 3. Predetermined gaps 4 are defined between the inner cap 3 and the outer cap 5 in a state that the outer cap 5 is not pressed, and the outer cap 5 covers the inner cap 3 so as to be freely turned irrespective of the inner cap 3 when the outer cap 5 is turned counterclockwise. In the case where press portions 10 on the side face of the outer cap 5 are pressed, the outer cap 5 is deformed into an oval shape, and longitudinal grooves 7 formed in an inner circumferential face of the outer cap 5 are engaged with longitudinal ribs 6 formed on an outer circumferential face of the inner cap 3, whereby the outer cap 5 and the inner cap 3 are unitarily turned counterclockwise. |
