A closed injection moulded plastic closure () having a first closure part and a second closure part (). 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.

Closed injection moulded closure providing mating upper and lower parts coupled by integrally formed hinge connections

A coordinated multi axis hinge arrangement provides a snap action between stable open and closed states. When the hinges operate between the stable open and closed states across a dead center position, resilient forces imparted by torsionally rigid connecting elements of the hinge to adjacent hinge parts such as body and lid elements are transferred by coupling or transmitting areas adjacent the bending regions or film hinges to remote resilient distortion or deformation energy storage areas. As the hinge passes a dead center position, this energy is in turn supplied and returned to the rigid connecting elements to impart snap action to the closure. The closure may be cast as a single piece of plastic material and may be cast in the open position.
