A stopper incorporates a base (1) with a pouring opening (15) and a one-piece cap (2) divided into two sections. The cap (2) is connected to the base (1) through a flexible-strip hinge (3). The part (20) of the cap (2) closer to the flexible-strip hinge (3) and the part (21) further from the hinge are connected to each other through a snap hinge (4). There is at least one opening (17) in the base (1) in which a matching catch (26) on the part (20) engages, whereas the part can still be opened and closed freely through the snap hinge (4).
