ABSTRACT:
The invention relates to a welded-in plastic spout part that is to be joined to a plastic receptacle part, especially a receptacle part made of film-type plastic material such as a pouch. The inventive spout part comprises parallel planar weld-on ribs which extend along the circumference of a neck area (spout) that defines a pouring passage. A rib-shaped welding burr that is less thick than the weld-on ribs is provided at the outer circumference of said weld-on ribs. The welding burr is molded onto an outer rounded peripheral edge of the weld-on ribs. A partition which protrudes radially on both sides of the neck area is arranged perpendicular to the weld-on ribs. Both ends of said partition extend beyond the ends of the rib base area so as to form lateral flaps. The welding burrs extend past both sides of the flaps while the lateral flaps are provided with one respective recess instead of a top and bottom outer corner.
