<p>A closure device, which comprises a container (21) and a cap (1) of synthetic resin adapted for closing a mouth (21A) of the container and having a tamper-evident property, and the container therefor. The closure device comprises a container (21) and a cap (1) of synthetic resin mounted to a mouth (21A) of the container. The cap (1) of synthetic resin comprises a cap body (4) composed of a roof plate (2) and a cylindrical portion (3) suspending from a peripheral edge of the roof plate, and the cylindrical portion (3) is sectioned into a main portion (8) above a severable weakened line (7) and a tamper-evident ring portion (9) below the severable weakened line, the main portion (8) being formed at its inner wall surface with a threaded portion (10) and the tamper-evident ring portion (9) being formed at its inner wall surface with fallable latch projections (11). The container (21) comprises a male thread (22) formed on a top outer periphery of the mouth (21A), an annular bulged portion (23) formed below the male thread (22), and at least one depressing portion (24) provided contiguous to the bulged portion (23) and adapted for engaging with the latch projections (11) of the cap (1) to depress the latch projections (11) when the cap (1) of synthetic resin mounted to the container mouth (21A) is turned in a cap opening direction.</p> |
