The invention relates to a self-opening closure with a pouring spout (), a self-opening sleeve () which is guided in the connector in a helical manner, and a cover () which covers the pouring spout (). A driver cam () is formed on the self-opening sleeve, said driver cam defining a guide surface (). The cover has a driver () which defines a front edge (). The front edge interacts with the guide surface of the driver cam. The front edge and the guide surface are inclined by the same angle of inclination relative to the longitudinal axis in order to allow an optimal force transmission between the cover and the self-opening sleeve. Additionally, the guide surface can be designed in a concave manner, and the front edge of the driver can be rounded in a corresponding manner in order to prevent a radial deflection of the driver towards the inside.

Self-opening closure with optimized force transmission

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be fastened in the region of a pour opening of the container and which has an opening through which the fluid can be withdrawn from the container, having a first closure element which in a closed position thereof effects fluid-tight sealing of the opening of the base element and which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.
