         15 . A device for a package where the packaging closure is build up of a cap, which is mounted on a package neck—henceforth called neck—and where the cap and the neck has cooperating sealing elements, one sealing lip at the neck which is pressed against cooperating surfaces, alternatively the sealing lip in combination with an additional sealing lip and the cap has in its interior a plane snapping in at an exterior plane of the neck and/or that the cap has a anti-tamper seal with an interior plane snapping in under a lip at the neck, and in the upper parts of the cap and the neck there is cooperating sections of the radius who guarantee that the cap and the neck in their final mounting position are fixed to each other in both axial and radial direction and wherein the neck preferably is welded to the package and that the cap is designed in a way that these interior surfaces always are entirely sealing separated from areas in the neck and the cap, and by that a package closure is obtained which secure a sterile environment in the package. 
     
     
         16 . The device according to  claim 15 , wherein the sealing lip in the upper part of the neck, is directed in to the center of the package and that the sealing lip is pressed against a exterior wall of a interior ring section of the cap when the cap is mounted on the neck, and by that a delimitation outwards from the package, a partition wall between the interior surfaces of the package and the remaining exterior surfaces of the cap is obtained. 
     
     
         17 . The device according to  claim 15 , wherein the cap in its upper part has the interior ring section with an extension orthogonal to a interior upper surface and where the ring section has the exterior wall situated on an approved distance from the cylindrical part located in the upper part of the neck and where the distance is variable according to the requirements set by the present application. 
     
     
         18 . The device according to  claim 15 , wherein on the exterior wall of the ring section there is a groove which by its position and shape is coordinated with a sealing nib of the cooperating sealing lip, and where the groove and the sealing nib fit together when the cap is finally mounted on the neck and by that an improved tightness and attachment function between the cap and the neck is obtained. 
     
     
         19 . The device according to  claim 15 , wherein a plane in the interior upper surface of the cap has an inclination relative the horizontal plane at preferably 15-30° and with its lowest point at the exterior edge of the plane and this to get a improved sealing function between the lip and the exterior wall of the interior ring section in connection with that the cap is mounted at its finally position on the neck and that this improved sealing function is obtained because the upper part of the neck, with the cylindrical part with an exterior part will be turned when the cap firstly is pressing against the exterior corner on the part, wherein the sealing lip of the neck will be moved inwards and up to the center of the package and then press harder against the cooperating exterior wall of the cap. 
     
     
         20 . The device according to  claim 18 , wherein the sealing function between the sealing lip and the cooperating part of the cap is improved when an interior positive pressure is developed in the package, since the sealing lip at these operating cases are influenced by a force aimed to move the sealing lip upwards from the package, but this is prevented by the exterior wall of the cap and, consequently, a improved surface pressure is established between the sealing lip and the exterior wall. 
     
     
         21 . The device according to  claim 15 , wherein the cap in its upper part has the plane which in its exterior part changes over to an outwardly directed inner section of the radius which in its lower part changes over to an almost cylindrical section extending downwards to the section provided with internal threads and where the cylindrical section is diametrically coordinated with the exterior part of the neck, to give a guide into the cap relative the neck and where the section of the radius at the cap gives one in axial direction guided fixed, finally mounting position for a cooperating section of the radius at the neck and its part and by that the neck and the cap is locked in their upper zone, which guarantee that the parts not moves axially in relation to each other and, consequently, this implies that also the sealing lip at the neck is axially locked in relation to the exterior wall of the cap. 
     
     
         22 . The device according to  claim 15 , wherein in the intern plane of the cap there is a recess located on an approved distance from an interior corner of the plane and is, according to dimensions and position, coordinated with a heel of the upper part of the neck and this design of the cap and the neck gives the construction a retention of the both cooperating parts neck and cap in radial direction, which function is important because this retention guarantee the contact pressure between the sealing lip and the cooperating exterior wall also in those operating cases when variations in pressure and temperature appears in the whole package. 
     
     
         23 . The device according to  claim 15  and in an embodiment where the cap and the neck of the package both are manufactured according to a second alternative of embodiment, wherein the sealing lip in the upper part of the neck is directed into the center of the package and is situated in a top plane of the neck. 
     
     
         24 . The device according to  claim 23 , wherein the sealing lip is pressed down against the package when the cap is mounted on the neck and this owing to that the inner ring section first bends away the sealing lip and is then displaced downwards and passes the outer end of the sealing lip, whereby the sealing nib of the sealing lip comes with force to be situated in contact with the outer wall of the ring section. 
     
     
         25 . The device according to  claim 23 , wherein as soon as the sealing lip with its sealing nib is in contact with the outer wall of the inner ring section of the cap a fully tightness is obtained in the package, even if the cap isn't mounted in its final position. 
     
     
         26 . The device according to  claim 23 , wherein the package is recloseable, i.e. that it always gives a fully tightness, the same tightness as in the initial phase, and this due to the interior elasticity provided in the sealing lip which implies that the lip cooperates with the inner ring section with pressure. 
     
     
         27 . The device according to  claim 15  and in an embodiment where the cap and the neck preferable both are realized according to a third alternative of embodiment, wherein the first sealing lip in the upper part of the neck is directed inwards to the center of the package and placed in the upper plane of the neck and that there also exists the second sealing lip, placed on the neck and in the same upper plane, but where the sealing lip is directed outwards from the center of the package and where the sealing lip is provided with a sealing tip which, when the cap is mounted on the neck, will be pressed against the cylindrical section of the cap and when a negative pressure is obtained in the package the sealing lip will seal even more tight against the cap and the cylindrical section. 
     
     
         28 . The device for a package where the cap is realized according to any of the different alternative constructions of cap and neck, but where the plane of the cap and the plane of the neck who cooperates with the plane, is replaced with a anti-tamper seal which in the final position of the cap snaps over the external located lip on the neck, and when this anti-tamper seal snaps over the lip the internal plane of the anti-tamper seal will lock the cap in axial direction relative the neck, since the lip in this position is elastic pressed against the outer corner at the inner plane of the anti-tamper seal.
