The closure consists of a lower closure part, which forms a drinking and pouring neck, in addition to a closure cap, which is pivotally connected to the lower closure part by a hinge. The drinking and pouring neck sits in a planar disc, onto which the hinge of the closure cap is formed. Below the disc, the drinking and pouring neck is surrounded by a deformable wall that forms a cone or dome, said wall extending obliquely downwards from the neck and being connected to the outer edge of the lower closure part. The drinking and pouring neck projects beneath the underside of said deformable wall and the lower edge of said neck forms at least two piercing elements. A spacer strip is formed onto the lower edge of the closure cap by means of one or more material bridges that act as predetermined breaking points. The spacer band guarantees that the cap has never been opened.
