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 (33.1, 33.2) of the hinge to adjacent hinge parts such as body and lid elements are transferred by coupling or transmitting areas (45.1, 45.2) adjacent the bending regions (34.1 - 34.4) or film hinges to remote resilient deformation energy storage areas (40.1 - 40.3). As the inge 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.

Un agencement de charnières à axes multiples coordonnés produit une détente brusque entre des états ouvert et fermé stables. Lorsque les charnières agissent entre les états ouvert et fermé stables, en passant par une position au point mort, les forces élastiques exercées par les éléments de liaison (33.1, 33.2) rigides en torsion de la charnière sur les parties de la charnière adjacentes, telles que le corps et le couvercle, sont transférées par des zones d'accouplement ou de transmission (45.1, 45.2) adjacentes aux zones de flexion (34,1 - 34.4) ou aux charnières en feuille, à des zones éloignées (40.1 - 40.3) de stockage de l'énergie de déformation élastique. Lorsque la charnière passe par la position de point mort, cette énergie est à son tour renvoyée aux élément de liaison rigides, de sorte qu'une détente brusque soit exercée sur la fermeture. La fermeture peut être coulée comme une simple pièce de plastique, et ce en position ouverte.
