## 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°.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The closure according to claim 1 wherein the first and second pair of film hinges are arranged at an angle Φ to each other, and the first and second plane defined by the first and second pair of film hinges are arranged at an angle ω, the angle Φ and an opening angle α of the closure is:

### Claim 3 (depends on 1)

The closure according to claim 1, wherein the opening angle α is in the range of 180° and 240°.

### Claim 4 (depends on 1)

The closure according to claim 1, wherein the trapezoid elements are separated by a cutout.

### Claim 5 (depends on 1)

The closure according to claim 1, wherein the trapezoid elements are connected by a film hinge along a shorter edge.

### Claim 6 (depends on 1)

The closure according to claim 1, wherein the body and the lid are connected by tamper evidence means, which are destroyed by initial opening.

### Claim 7 (depends on 1)

The closure according to claim 1, wherein the body and the lid are in the open position spaced a distance s apart, whereby, the distance s is equal to 50% to 90% of the shorter edge of trapezoid elements.

### Claim 8 (depends on 1)

The closure according to claim 1, wherein said closure is characterized by a cylindrical outer wall section.

### Claim 9 (depends on 1)

The closure according to claim 1, wherein the first and the second trapezoid elements, and the first and second pair of film hinges are arranged along the inner wall of the closure, wherein the inner wall is formed by the body and the lid, such that no overlapping exists in an x-direction to allow easy demoulding after moulding is complete by releasing one of two mould halves on an outer side in the x-direction and at the same time releasing the other one of the mould halves to the other side in the x-direction, whereby the x-direction is vertical to the z-direction and also vertical to the direction in which the first and the second trapezoid elements are spaced apart from each other.

### Claim 10 (depends on 1)

The closure according to claim 1, wherein the inner periphery of the hinges are configured such that they do not protrude beyond a maximum inner radius (R1) of the closure.

### Claim 11 (depends on 1)

The closure according to claim 1, wherein the film hinges are defined by a plane on the inside of the closure and the outside of the film hinges are defined by two flat boundary planes, arranged at an angle K to each other, and a cylindrical boundary surface having a radius (R3).
