Provided are a cap capable of being easily and reliably opened and unsealed, not limited in design even if an inner cap with a small diameter is used for the cap, producing no refuse after the unsealing, and not unnecessarily large in size, and a container with the cap. When an over cap (3) is rotated in the opening direction, a pair of screw threads (10a, 10b) as opening means are advanced in the direction in which they are tightened together, and this cuts off an planned opening section (4) from the inner cap (2). Thus, the cap has a relatively simple structure and can be simply and reliably unsealed by small force. Further, it is enough if the screw threads (10a, 10b) can be formed in the region of the opening, so that the structure can be applied to a cap with an inner cap with a small diameter and the design of the cap (1) is not limited. Also, the planned opening section (4) is integrated with the over cap (3) after unsealing the inner cap (2), so that no refuse is produced after the unsealing, eliminating the need to clear it away from a table. |
