US Patent 7334694 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).
