Abstract
The invention is directed to a closure moulded in closed position. The closure comprises a body and a lid, which are separated by a circumferential gap. A snap hinge comprising two trapezoid elements which are connected each by film hinges to the body and the lid, causes a snap action while opening or closing the closure. The closure offers opening angles in the range of 220°.

A closure moulded in closed position with a body comprising fixing means to fix the closure on a neck of a bottle, and a lid, the lid comprising a sealing means to seal an orifice of the bottle, whereby the body and the lid are separated from each other by a circumferential gap and at least one of the body and the lid form a closure wall, the closure further comprising:
- a snap hinge comprising a first and a second trapezoid element that are spaced apart from each other, and
- a first and second pair of film hinges, each pair defining a first and second plane, respectively, the first and second pair of film hinges connecting the first and second trapezoid elements to the lid and the body, where
- the first and second plane are arranged substantially parallel to an axis A of the closure when the closure is in the closed position, wherein
- the film hinges are positioned along an inside of the closure wall, an inside of the film hinges is configured such that the film hinges are easily demoulded in a z-direction, which is a direction of the axis A of the closure, and
- an inner periphery of the film hinges is arranged as a secant to a circle having a radius equal to a maximum inner radius (R1) of the closure.
