摘要：
The invention relates in particular to a plastic suds container, which due to the manufacturing process has joint lines, which are produced in particular during injection molding by means of a plurality of gates. The component according to the invention is characterized by elongated joint lines, the shapes of which have been changed. Perpendicularly with respect to the extension thereof, the intersection lines of the joint lines have deformations which are bell-shaped or are broken up in some areas. Components of said type have increased strength in the region of the joint line. The danger of cracks forming in the region of the joint lines is minimised. In the method for producing such a component, the delivery of plastic material via at least one of the gates present in the injection mould briefly takes place at reduced pressure or is briefly interrupted. The control is done via valves in the feed lines to the injection mould. The time frame for the control is determined by means of simulation or empirically
