Abstract: The invention relates to a closure for a container for holding a fluid, more particularly an adhesion promoter composition, provided, having a base element which can be fastened in the region of a pour opening of the container and which has an opening through which the fluid can be withdrawn from the container, having a first closure element which in a closed position thereof effects fluid-tight sealing of the opening of the base element and which in an open position thereof releases the opening of the base element, and having a second closure element, which can be fastened to the base element in such a way as to be repeatedly releasable and which, in a container storage mode, secures the first closure element in its storage position and, for a container dispensing mode, releases the first closure element to bring it from its closed position into the open position.
