A guarantee closure having a closure body with a guarantee foil and a pour-out spout as well as a closure cap fitting onto the closure body. The pour-out spout is arranged on the closure body such that it may be pivoted up. The guarantee foil, by pivoting-up the pour-out spout into the pour-out position, is cut open and thus frees the passage to the pour-out spout. The closure body comprises a relief for receiving the guarantee foil and forms above the relief, by two shoulders arranged over one another and distanced from one another, a free space for receiving the lying pour-out spout. This is enclosed and held by a film-hinge material bridge which in the lying condition connects the two shoulders with a surface which seen from the outside is concave and on the upper side of the lying pour-out spout runs together to a point which defines the pivoting axis of the pour-out spout. On pivoting up the pour-out spout the film-hinge material bridge snaps into a permanent shape which is convex when viewed from the outside and thus holds the pour-out spout in the closure position.
