Claim 14:
15. Closure (100) according to claim 1, wherein said base element (200) has a tongue member (260) extending from an upper region or an upper plane of said base member (200) into an upward direction along the vertical axis (z-axis), wherein said flip-top lid (300) has a protrusion (360) extending outwardly from said flip-top lid (300) in a direction being normal to the vertical axis (z-axis), said tongue member (260) and said protrusion (360) being positioned and arranged such that, during a movement of said flip-top lid (300) between its fully closed and its fully opened position, said protrusion (360) and said tongue member (260) are, over a first predetermined angular range of the position of the flip-top lid (300) relative to the base element (200) during its movement between its fully closed and its fully opened position, in contact with each other, such that the protrusion (360) exerts a force onto said tongue member (260) into an inward direction and said tongue member (260) exerts a counterforce to said protrusion (360), such that, when said flip-top lid (300) is within a second predetermined angular range relative to said base element (200), said counterforce supports a movement of said flip-top lid (300) in a direction towards its fully opened position, wherein said tongue element (260) or an outer surface thereof preferably extends, in an upper part thereof, at least partly into an inward direction.
