Abstract
A two-part hinge closure having a lower part which has a surrounding outer wall and which can be placed on a container, and has a cap which has an outer wall and which can be joined to the lower part in a hinged manner. The lower part and the cap are separately produced and can be assembled together. In an assembled and closed state, the outer walls are situated above each other in an aligned manner, at least in the hinge area of both hinge closure parts. Both closure parts can be joined to one another by a snap hinge having at least one spring element and at least one coupling piece. When the closure is in a closed state, the at least one spring element and the at least one coupling piece are at least almost aligned with the outer wall of the closure part on which they are formed as one piece.
