Abstract:
The purpose of the present invention is to provide a synthetic resin cap and a container, capable of preventing longitudinal cracking of a tamper-evident band. The cap (1) is equipped with: a skirt wall (3) provided with a female screw (5) to be screwed onto a male screw (M1) formed on the outer periphery of a container mouth section (M); and a tamper-evident band (9) connected to the bottom of the skirt wall (3) via an annular weakened part (10). Multiple hooks (11) lockable, from below, to annular protrusions (M2) provided on the outer periphery of the container mouth section (M) are provided on the inner peripheral side of the tamper-evident band (9) with gaps therebetween in a circumferential direction. The female screw (5) is an intermittent screw comprising alternately arranged threads (16) and unthreaded parts (17), and is configured such that no gaps (18) disposed between circumferentially adjoining hooks (11) are positioned on extensions of the unthreaded parts (17) in an axial direction of the skirt wall (3).
