Abstract

An injection molding tool includes first tool part displaying, at inlet of mold cavity, a continuous throttle lip which projects in a direction which coincides with the first flow direction. - An injection molding tool comprises first tool part(s) (1a, 1b) adapted to be brought into contact with a first side of a packaging material, and second tool part(s) (2) adapted to be brought into contact with a second side of the packaging material, in such a manner that there is formed a mold cavity (7) which surrounds the hole edge, together with a part of the first side and a part of the second side in connection with the hole edge. The mold cavity displays an inlet for molten plastic and, opposing the inlet, an end gap for the extension of the packaging material out of the tool. The end gap is located between the first and second tool parts. The inlet displays a deflection from a first flow direction in a flow gap (5) to a second flow direction into the mold cavity. The first tool part, at the inlet displays a continuous throttle lip which projects in a direction which substantially coincides with the first flow direction. - Independent claims are also included: - (1) a packaging container displaying an injection molded opening arrangement of plastic disposed in a hole in a packaging material comprising an elongate and continuous depression in the opening arranged at deflected portion. The depression has a depth which coincides with the first direction of extension of the edge portion; and - (2) a method of injection molding an opening arrangement of plastic in a hole in a sheet or web shaped packaging material. The hole defines an edge which is surrounded by a mold cavity. The cavity includes an inlet to introduce molten plastic, and an end gap for the extension of the packaging material out of the cavity. A flow of molten plastic is deflected at the inlet from a first flow direction to a second direction into the cavity past a continuous throttle lip which projects in a direction corresponding with the first flow direction.
