Process for manufacturing a closure device for a container in which a flowable material is stored, comprising - a base element, which can be fastened on a container opening of the container - a spout with a dispensing opening • whereby the spout is positioned inboard of the base element, and - a lid connected to the base element by a hinge, • whereby the lid can be moved back and forth between a closed position in which the lid closes the dispensing opening so that the flowable material is retained in the container and an open position in which the flowable material can be released from the container, - tamper evidence indication means for visually indicating if the lid of closure device has once been moved out of its closed position, wherein the manufacturing process comprises the following steps: • Moulding of the base element, the lid and the hinge with the lid being moulded in its open position, • Closing of the lid to the base element, • Moulding of the tamper evidence indication means, whereby the tamper evidence indication means comprising a first indication ring and a second indication ring being coaxially positioned to each other and which are connected by at least one radially oriented frangible bridge, • Assembly of the tamper evidence indication means into the base element and the lid, • Assembly of the spout into the base element, characterized in that the first indication ring has a first axial height and the second indication ring has a second axial height whereby in the non-disrupted condition the second axial height is completely covered by the first axial height. - a base element, which can be fastened on a container opening of the container - a spout with a dispensing opening • whereby the spout is positioned inboard of the base element, and • whereby the spout is positioned inboard of the base element, and - a lid connected to the base element by a hinge, • whereby the lid can be moved back and forth between a closed position in which the lid closes the dispensing opening so that the flowable material is retained in the container and an open position in which the flowable material can be released from the container, • whereby the lid can be moved back and forth between a closed position in which the lid closes the dispensing opening so that the flowable material is retained in the container and an open position in which the flowable material can be released from the container, - tamper evidence indication means for visually indicating if the lid of closure device has once been moved out of its closed position, wherein the manufacturing process comprises the following steps: • Moulding of the base element, the lid and the hinge with the lid being moulded in its open position, • Closing of the lid to the base element, • Moulding of the tamper evidence indication means, whereby the tamper evidence indication means comprising a first indication ring and a second indication ring being coaxially positioned to each other and which are connected by at least one radially oriented frangible bridge, • Assembly of the tamper evidence indication means into the base element and the lid, • Assembly of the spout into the base element, • Moulding of the base element, the lid and the hinge with the lid being moulded in its open position, • Closing of the lid to the base element, • Moulding of the tamper evidence indication means, whereby the tamper evidence indication means comprising a first indication ring and a second indication ring being coaxially positioned to each other and which are connected by at least one radially oriented frangible bridge, • Assembly of the tamper evidence indication means into the base element and the lid, • Assembly of the spout into the base element, characterized in that the first indication ring has a first axial height and the second indication ring has a second axial height whereby in the non-disrupted condition the second axial height is completely covered by the first axial height.
