Closure device

A closure device for a container in which a flowable material is stored, said closure device 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;
• 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 spout is not accessible and an open position in which the spout is accessible;
• and
• tamper evidence indication means for visually indicating if the lid of the closure device has once been moved out of its closed position, wherein the tamper evidence indication means comprise a first indication ring and at least a second indication ring which is co-axially arranged in the first indication ring, whereby the first indication ring and the second indication ring are connected by at least one radially oriented frangible bridge which is configured to be disrupted when the lid is moved from its closed position, causing an axial movement of the first indication ring relative to the second indication ring, whereby the first indication ring has a first optical property and the second indication ring has a second optical property being different form the first optical property, the lid comprises a spout sealing ring which projects from the lid bottom axially inwardly into the closure device and which contacts the outer surface of the spout, whereby the second indication ring is connected to the spout sealing ring.
