Abstract:
1. A plastic spout which is adapted to be sealed between two foil walls of a pouch, comprising an injection moulded single part spout body comprising: (a) a transverse wall; (b) two thin, flexible sealing walls forming a sealing zone for a sealed connection to an adjoining foil wall, that each have an upper edge adjoining the transverse wall, wherein the two sealing walls have a length and adjoin one another at the outermost ends, wherein the sealing walls freely project perpendicularly downwards over a height from said transverse wall, said flexible sealing walls between them delimiting an open, oval space having essentially the same cross-sectional dimension over the height of the sealing walls, the dimension of the transverse wall exceeding that of the cross-section of the oval space, and said flexible sealing walls each have a curvature over the entire length of the sealing walls as viewed from below the spout, such that each sealing wall is outwardly convex over the entire length of the sealing walls with respect to an imaginary plane passing through the outermost ends of the sealing walls; (c) thin lips, each formed at the location where the outermost ends of the sealing walls meet and projecting outwardly in said imaginary plane; and (d) an upwardly projecting cylindrical tubular part having a lower end adjoining the transverse wall, said tubular part projecting perpendicularly upwards from said transverse wall, the cross-section of the oval space exceeding that of the cross-section of the cylindrical tubular part, said tubular part forming at least a part of a passage that extends through the transverse wall and is in communication with said oval space for delivering a medium from the pouch or feeding a medium to the pouch, said tubular part including screw thread.
