Abstract
A closure for a rigid or deformable container. The contents of the container are protected by a seal. The closure has a bottom part and a cap fixed thereon by a hinge. The lower part is closed by a cover face, through which only a pouring spout extends. A tear-off element is positioned on an underside of the cap in such a way that it extends through the pouring spout as far as the seal located below it. The tear-off element is in active contact with the seal, for example, it is bonded or glued to it. At the time of a first opening, the tear-off element pulls the seal upwards, which is simultaneously broken by a cutting element below the pouring spout. Such closures are structurally simple in their manufacture as well as in operation and can be attached to various types of containers.

A closure in combination with a container, in which contents of the container have been sealed, the closure comprising:
- a seal (40), at least one tear-off element (23, 66) in active connection with said seal (40), said at least one tear-off element (23, 66) provided on the closure, and tearing the seal in a direction of opening when the closure is opened a first time;
- said container having a container neck (31), said seal (40) being one of a foil, a membrane of metal or a metal laminate positioned on the container neck (31), and wherein said seal and said tear-off elements being connected by a bonded or a glued spot;
- and
- said closure further comprising a bottom part (1) forming a pouring spout (6), a cap (2) pivotally connected with said bottom part (1), said tear-off element (23) on said cap (2) extending through said pouring spout (6) when the closure is in a closed position, and said bottom part (1) having a cutting element (14) directed towards said seal (40).
A closure for a deformable container in a shape of a bag, the closure comprising:
- a seal (40), at least one tear-off element (23, 66) in active connection with said seal (40), said at least one tear-off element (23, 66) provided on the closure, and tears the seal in a direction of opening when the closure is opened a first time, a bottom part (1) forming a pouring spout (6), a cap (2) pivotally connected with said bottom part (1), said tear-off element (23) on said cap (2) extending through said pouring spout (6) when the closure is in a closed position, and said bottom part (1) having a cutting element (14) directed towards said seal (40);
- and
- said bottom adapted to extend through a wall, said bottom part having a flange (15) for fastening to an inner wall surface of said bag, and said bottom part (1) closed with one of a foil or a membrane forming a seal (40) upon which said tear-off element (23) acts.
A closure for a deformable container in a shape of a bag, the closure comprising:
- a seal (40), at least one tear-off element (23, 66) in active connection with said seal (40), said at least one, tear-off element (23, 66) provided on the closure and tearing the seal in a direction of opening when the closure is opened a first time, a bottom part (1) forming a pouring spout (6), a cap (2) pivotally connected with said bottom part (1), said tear-off element (23) on said cap (2) extending through said pouring spout (6) when the closure is in a closed position, and said bottom part (1) having a cutting element (14) directed towards said seal (40);
- and
- said cap (2) adapted to sealingly connect with an outside surface of a wall of said bag with a flange (15), said wall of said bag underneath said bottom part (1) forming a seal (40) to be broken.
A closure in combination with a container, in which contents of the container have been sealed, the closure comprising:
- a seal (40), at least one tear-off element (23, 66) in active connection with said seal (40), said at least one tear-off element (23, 66) provided on the closure and tearing the seal in a direction of opening when the closure is opened a first time;
- said container having a container neck 31, said seal (40) being one of a foil, a membrane of metal or a metal laminate positioned on the container neck (31), and wherein said seal and said tear-off elements (23, 66) being connected by a bonded or a glued spot;
- the closure having a bottom part (50) with a sealing pin (58) provided thereon, a top part (60) movably disposed above said bottom part (50), said top part (60) having a pouring opening (65) within which said sealingly pin (58) sealingly fits, and a tear-off element (66) in a form of a pipe segment positioned concentrically around said sealing pin (58) and in active connection with said seal (40);
- and
- radially outward directed cutting ribs (59) positioned on said sealingly pin (58) for breaking said seal (40).
