Abstract
A closed injection moulded plastic closure (20) having a first closure part and a second closure part (22). The first closure part is connected to the second closure part by snap-on hinged connection. The first and second closure parts have no main hinged connection with each other, but are connected to one another by two connecting elements and four hinged connections bordering the two connecting elements on nonadjacent sides. Coupling elements may serve as an original warranty seal for indicating opening for the first time. If required, a catch and a counter-element serve as a locking mechanism and prevent unintentional opening of the closure.
