Claim:
A guarantee closure for a liquid and free-flowing material container ( 20 , 20 ′) having a closure body ( 1 ) with a pour-out spout ( 2 , 2 ′) arranged therein in an initial position and which is pivotable up out of the initial position and which with respect to the closure body ( 1 ) is sealingly enclosed by a film-hinge material bridge ( 5 , 5 ′) which on pivoting up the pour-out spout ( 2 , 2 ′) springs from a concave into a convex shape and vice-versa and thus retains the pour-out spout ( 2 , 2 ′) in end positions of a pivoting range, and an associated guarantee foil ( 4 , 28 ) which in the lying position of the pour-out spout ( 2 , 2 ′) extends below and along the lying position, wherein a pivoting axis on the pour-out spout ( 2 , 2 ′) is at a location so that a rear section of the pour-out spout ( 2 , 2 ′) on pivoting-up the pour-out spout ( 2 , 2 ′) pivots downwards, the guarantee closure comprising: a lower, rear end of the pour-out spout ( 2 , 2 ′) in the lying position tapering into a tip ( 9 , 9 ′) and from a wall are formed two edges ( 10 ′) tapering at an askew angle to a pour-out spout axis to the tip ( 9 ′), the tip ( 9 ′) tapering into a perforating tip ( 27 ) by forming one of a plastic cone pointing toward the guarantee foil ( 28 ) and a large-surfaced plastic triangle aligned along the pour-out spout axis, with a sharp tip directed downwards, the pour-out spout ( 2 , 2 ′) in the lying position forming on a lower longitudinal side behind the film-hinge material bridge ( 5 , 5 ′) a sharp wedge-shaped longitudinal edge, and on pivoting up the pour-out spout ( 2 , 2 ′) at first the guarantee foil ( 28 ) being pierced open by the perforating tip ( 27 ) and then starting at the piercing point being cut open by the longitudinal edge, the closure cap ( 3 ) via a film hinge ( 18 ) connected as one piece to the closure body ( 1 ) and can be flipped up whereby the closure cap ( 3 ) in a closed position is lockable into the closure body ( 1 ) and bears on an inner side a collar ( 22 ) which in a flipped up position of the pour-out spout ( 2 ) and closed closure cap ( 3 ) encloses an opening edge of the pour-out spout ( 2 ) so that the pour-out spout ( 2 ) in the flipped up position is sealed and secured.
