The present invention relates to a closure or cap for a container containing a fluid. The closure or cap is characterized in that the slotted structure comprises several pivoting plates hinged to the body in such a way as to be able to pivot; at least one pivoting plate, preferably each pivoting plate, being connected movably to a neighbouring pivoting plate via a cross section of more flexible deformation than the several pivoting plates, which forms one of the free terminal edges of the slot or slots and is, in a condition of actuation without overpressure inside the container, arranged basically contiguously with the other free terminal edge situated opposite the slot or slots and can open by pivoting away from the inside of the container when the fluid generates increased pressure inside the container, whereupon it moves away from the other free terminal edge.
A closure for a container containing a fluid, comprising a body with an outlet opening, via which the fluid is discharged when it generates a container-internal excess pressure, and which is bounded by a slotted structure with at least one slot, which is defined by free terminal edges facing each other and ending in a common apex, characterized in that the slotted structure comprises multiple pivoting plates, which are hinge-connected to the body so that they can pivot, wherein at least one pivoting plate is connected to an adjacent pivoting plate so as to be moveable, via a deformation section that is more flexible relative to the multiple pivoting plates and forms one of the free terminal edges of the at least one slot, and in an activation state free of a container-internal excess pressure is arranged essentially adjacent to the other opposite free terminal edge of the at least one slot, and when the container-internal excess pressure is generated by means of the fluid can be pivoted upwards away from the container interior and is thus removed from the other free terminal edge.
