Container closure

Abstract

The invention relates to a container closure for closing a pouring opening of a container which is filled with a liquid, having: a closure cap, which has a free edge, a shell and a top plate; a tamper-evident ring, which is designed to be retained form-fittingly on a container neck of the container; and a retaining element having a first and a second end, the first end being firmly connected to the free edge of the closure cap and the second end being firmly connected to the tamper-evident ring. The closure cap is transferable from a closure position, in which it closes the pouring opening, into an open position, in which it fully opens up the pouring opening, and vice versa. An adhesion surface for improving the adhesion of liquid is provided on the inner side of the top plate coming into contact with liquid.
