Closure cap cooperating with a bottle container

The invention relates to a closure cap ( 1 ) which cooperates with a bottle container ( 4 ). A catching protection ( 5 ) is disposed on the neck ( 3 ) of the bottle container ( 4 ) and a lower-engaging projection ( 6 ') is disposed on the closure cap ( 1 ). An insert ( 2 ) is associated with the closure cap ( 1 ). Said insert ( 2 ) can be fixed to the neck ( 3 ) of the bottle, resulting in a structurally advantageous, functionally reliable solution whereby the insert ( 2 ) is provided with means ( 22, 26 ) for rotationally secure retention on the neck ( 3 ) of the bottle and the closure cap ( 1 ) which can be pressed onto said insert ( 2 ) can be unscrewed from the insert ( 2 ).
