1. A spout comprising: a spout part having an inlet opening and a spout opening, anda flange part connected to the spout part,wherein the flange part has two sides, an attachment side as well as a rear side, wherein the attachment side is oriented towards the spout part and is provided for the attachment at a laminated package, wherein an oxygen impermeable film is arranged at the rear side of the flange part and is welded to the rear side such that the spout part is sealed towards the rear side only by the film, and wherein the film has an end section,wherein the flange part has a weld extending in its circumferential direction which weld is configured such that the end section is welded at the two sides in the flange part; andwherein the end section is arranged below the attachment side and the end section is arranged extending in the flange part, such that a spacing between the end section and the attachment side reduces in the direction towards a periphery of a flange part. 2. The spout in accordance with claim 1, wherein the thickness of the flange part reduces towards the periphery, such that the mutual spacing between the attachment side and the rear side reduces. 3. The spout in accordance with claim 1, wherein the end section extends tilted or curved with respect to the attachment side. 4. The spout in accordance with claim 1, wherein the film including the end section extends in parallel to the attachment side. 5. The spout in accordance with claim 1, wherein the end section ends at an end face and in that the spacing between the attachment side and the end face lies in the region of up to 0.5 mm. 6. The spout in accordance with claim 1, wherein the flange part is configured such that the laminated package welded to the attachment side and the film arranged at the rear side mutually overlap by a distance of at least 1 mm, preferably by a distance of up to 5 mm, with respect to the flange part in the radial direction. 7. The spout in accordance with claim 1, wherein the end section has an end face and in that the end section, as well as the end face of the film are welded to the flange part in gas-tight manner. 8. The spout in accordance with claim 7, wherein the weld, in which the end section is welded in from both sides, extending in the circumferential direction is configured as a bead-like sealed part. 9. A container closure comprising: a spout in accordance with claim 1, further comprising: a screw cover having an inner thread and an axis of rotation, anda cutting part which is arranged within the spout part, wherein the cutting part has an outer thread and the spout has an inner thread, which threads engage with one another and are configured such that the cutting part moves in the direction of the axis of rotation (D) towards the film on an opening of the screw cover,wherein the screw cover comprises an engagement part, and wherein the cutting part and the screw cover are configured mutually adapted such that the engagement part transfers a torque onto the cutting part. 10. The container closure in accordance with claim 9, wherein the engagement part extends in the direction of extent of the axis of rotation (D); in that the cutting part has a lug for receiving the engagement part, wherein the lug is configured such that the engagement part is displaceably stored with respect to the lug in the direction of extent of the axis of rotation (D) and in this connection a form-fitting connection is formed. 11. A semi-finished product for a spout in accordance with claim 1, comprising a spout part having an inlet opening and an outlet a spout opening, anda flange part connected to the spout part,wherein the flange part has two sides, an attachment side as well as a rear side,wherein the attachment side is orientated towards the spout part and is provided for the attachment to a laminated package, wherein the rear side has a nose extending along its periphery in the circumferential direction and projecting over the rear side,wherein a film, which also covers the inlet opening, is arranged in a region of the rear side enclosed by the nose part, wherein the film has an end section directed towards the nose part and wherein the nose part is transformed to a sealed part such that the sealed part encloses the end section in the circumferential direction and the end section of the film is welded at both the two sides in the flange part; andwherein the end section is arranged below the attachment side and the end section is arranged extending in the flange part, such that a spacing between the end section and the attachment side reduces in a direction towards a periphery of the flange part. 12. The semi-finished product in accordance with claim 11, wherein the rear side has a thinnest point at which the spacing between the attachment side and the rear side has the smallest value and in that, opposite the thinnest point, the attachment side has an energy directing actor projecting beyond the attachment side. 13. The spout in accordance with claim 1, wherein the flange part has a first weld connecting the film to the rear side, wherein the first weld is arranged in the region of the inlet opening and extends over the overall circumference of the rear side. 14. The spout in accordance with claim 13, wherein this has a second weld connecting the film to the rear side, wherein the second weld is arranged with respect to the end section and extends over the overall circumference of the rear side. 15. The spout in accordance with claim 14, wherein the flange part has a venting hole between the first weld and the second weld which venting hole forms a fluid conducting connection between the attachment side and the rear side. 16. A method of manufacturing a spout, comprising a spout part having an inlet opening, as well as having a spout opening, anda flange part connected to the spout part,wherein the flange part has two sides, an attachment side as well as a rear side, wherein the attachment side is oriented towards the spout part,wherein a nose part is arranged at the rear side, said nose extending in the circumferential direction and projecting over the rear side,wherein a film, which also covers the inlet opening, is arranged in a region of the rear side enclosed by the nose part, wherein the film has an end section directed towards the nose part and wherein the nose part is transformed to a sealed part such that the sealed part encloses the end section in the circumferential direction and the end section of the film is welded at the two sides in the flange part; andwherein the end section is arranged below the attachment side and the end section is arranged extending in the flange part, such that a spacing between the end section and the attachment side reduces in a direction towards a periphery of the flange part. 17. The method in accordance with claim 16, wherein the flange part is generated with a thickness reducing towards the nose part such that the spacing between the film and the attachment side reduces at least in the region of the sealed part for a welded film. 18. The method in accordance with claim 17, wherein the rear side is formed with a surface extending curved in a direction towards the nose part. 19. The method in accordance with claim 16, wherein the welding is carried out with ultrasound, in order to bring about a gas-tight connection in the sealed part between the end section of the film and the flange part. 20. The method in accordance with claim 19, wherein material of the nose part is urged in a direction towards the inlet opening during the ultrasonic welding, such that the end section is covered with material at the side remote from the rear side and, in this connection, the sealed part is formed, wherein the sealed part is preferably configured as a bead-shaped. 21. The method in accordance with claim 20, wherein a sonotrode has a form surface having a part form surface extending tilted and/or extending transverse, oblique or radial with respect to an extent of the attachment side and in that this part form surface acts on the projecting nose part in order to urge material of the nose part away in a direction towards the inlet opening.
