The present invention provides a closure cap for a container comprising a lid and a shell, and a hinge region for pivotally connecting the lid to the shell and for locking the lid in an open position thereof. The lid comprises a top panel having a tongue adjacent the hinge region and a cylindrical wall suspended from a bottom face of the top panel and connected to the shell via a plurality of bridges which break upon a first opening of the lid. The hinge region comprises a pair of elongate hinge elements spaced apart from each other, and a ratchet-like member disposed therebetween.
