ABSTRACT A one piece plastic closure comprises a lower part (1) a lid (3) and a snap hinge (6). In order to connect the lower part directly to the lid (3), the snap hinge comprises one or more film hinges (8) aligned in the main axis of rotation (10). The snap hinge comprises at least one elastic element (14) which in the closed position does not project beyond the external profile of the adjacent sections of the lower part and of the lid, but is as flush as possible with them. The elastic element is connected to the lid and to the lower part by linear articulation (16) parallel to the main axis of rotation at a certain distance from the latter. At least one film hinge is located with the necessary play on the outer faces of the lower part and of the lid. The sections of the lower part and of the lid immediately adjacent to the film hinge have edge surfaces (22, 24) inclined to their outer face bevelled edges which in the closed position are adjacent and in the open position swing apart. In the closed position of such a closure, the film hinges do not project outwardly, but are located in the outer wall of the lower part and in one edge of the outer wall of the lid. The lid and the lower part can also be connected together by a small strip (30) or by several aligned small strips. In this case the small strip is fully retracted inside the outer profile when the closure is closed.
