Pouring element for a package for holding flowable or pourable products and method of producing such a package
There is shown and described a pouring element for a package for holding flowable or pourable products, and particularly a cardboard/plastics composite package having a gabletop, said pouring element having a pouring passage, the pouring passage having passage cross-sections of substantially identical areas arranged perpendicularly to its centerline, the outer passage cross-sections of the pouring passage being a product inlet opening and a substantially circular product outlet opening and the product inlet opening having associated with it a flange for connection to the package. To enable improved pouring characteristics to be achieved without having to accept disproportionately large costs and complication in production, provision is made, in the form for application, for the product inlet opening to be of an elongated shape which is not symmetrical in rotation.
1. Pouring element ( 1 ) in the form for application for a package ( 10 ) for holding flowable or pourable products, and which is especially suitable for a cardboard/plastics composite package having a gabletop, said pouring element ( 1 ) having a pouring passage ( 2 ), the pouring passage ( 2 ) having a constant cross-sectional flow area along the centerline ( 5 ) of the pouring passage ( 2 ), the passage cross-section of the pouring passage ( 2 ) at one end of said pouring passage ( 2 ) being a product inlet opening ( 3 ) and the passage cross-section of the pouring passage ( 2 ) at the other end of said pouring passage ( 2 ) being a substantially circular product outlet opening ( 4 ), and the product inlet opening ( 3 ) having associated with it a flange ( 8 ) for connection to the package ( 10 ), characterised in that the product inlet opening ( 3 ) is of an elongated shape which is not symmetrical in rotation.
2. Pouring element according to claim 1 , characterised in that, in the form for application, the product inlet opening ( 3 ) is of a substantially oval or rectangular shape with rounded corners.
3. The pouring element according to claim 1 , characterised in that, in the form for application, the flange ( 8 ) is arranged substantially in one plane.
4. The pouring element according to claim 1 , characterised in that, in the form for application, the passage cross-section of the pouring passage ( 2 ) at said product inlet opening ( 3 ) is substantially oval, and in that said passage cross-section is increasingly circular with increasing distance from the product inlet opening ( 3 ).
5. The pouring element according to claim 4 , characterised in that, in the form for application, a portion ( 7 ) at the product outlet opening is of a substantially cylindrical form.
6. The pouring element according to claim 1 , characterised in that, in the form for application, the outer edge of the flange ( 8 ) is spaced approximately equally far away from the centreline ( 5 ) as the edge of the product outlet opening ( 4 ) at least at two points which are situated opposite one another.
