摘要：There are provided a screw-type cap which can cure necessary fastening torque (opening torque) even in a ca of a container having a plug having a foremost end portion of a small diameter and also a safety cap which cannot be opened by only rotation and therefore has a child resistance effect. A safety cap 20 consists of a screw-type inner cap 21 and an outer cap 22 which is mounted in such a manner that it covers the inner cap 21 and can be rotated and can displace axially within a limited distance. The outer cap 22 can rotate integrally with the inner cap 21 by pushing down the outer cap 22 and rotate it while the outer cap 22 rotates idly by rotation only. A plug portion 8 is formed by projecting a plug 6 from a disk portion 7 which is in abutting engagement with a tip end portion of a mouth portion 2 of the container. The inner cap 21 has a small diameter portion 21c formed in the inner middle portion thereof. The small diameter portion 21c is in abutting engagement with the disk portion 7 and controls interference by screwing. By causing the small diameter portion 21c of the inner cap 21 against the disk portion 7 of the plug 6, interference can be controlled to prevent excessive fastening and necessary fastening torque (opening torque) can be cured even in a ca where the cap has the plug portion having a small diameter while idle rotation can be cured to achieve a child resistance effect.
