PROBLEM TO BE SOLVED: To improve the operability for unsealing and resealing by providing a cap main body wherein a paritioning member is provided at an opening of a diameter contracted part having a protruding part which protrudes outside in the diametrical direction, and a sliding member having a lid part wherein an opening being closed by coming into contact with the partitioning member when being located at a lowermost position to the diameter contracted part, is formed. SOLUTION: For this cap under a non-opened state, a sliding member 11 is located at a lowermost position to a diameter contracted part 4, and a lid part 9 of the sliding member 11 comes into contact with a partitioning member 6, and an opening 8 is closed by the partitioning member 6. In order to unseal this cap, after opening an external lid member 13, the sliding member 11 is pulled up, and the cap is unsealed. Under this unsealed state, the sliding member 11 is located at an uppermost position to the diameter contracted part 4, and the lid part 9 is separated above the partitioning member 6, and a liquid in a container can be discharged from the opening 8 by passing through a liquid passage. Also, under this unsealed state, an engaging part 10 of the sliding member 11 engages with the lower end of a protruding part 3 being formed on the external surface of the diameter contracted part 4, of which the diameter is expanded in steps, and the sliding member 11 is prevented from moving further upward. |
