Abstract
A closure cap for a container comprises an inner cap which can be screwed onto the neck of a bottle, and an outer cap which covers and surrounds the inner cap. The outer cap has a tamper evident rim part of which extends into an annular groove in the inner cap. Portions on the top of the inner cap can be brought into engagement with portions provided under the top of the outer cap following downward movement of the outer cap. This downward movement of the outer cap enables rotation of the outer cap to effect removal of the cap, but such downward movement is only possible after the tamper evident rim has been removed.
