Abstract
A wall section of a coherent product, such as a container, includes at least two opposing plastic components. At least a first one of the opposing plastic components is injection molded and includes a wall of non-uniform thickness that defines some ribs and a web located between two of the ribs in a portion of the wall where the wall is less thick than in the ribs. At a cross section of the first plastic component, over the height of the ribs the predominant thickness across each of the two ribs is significantly thicker than the thickness of the web. At least the crest of a portion of the ribs of one of the plastic components directly or indirectly contacts another plastic component, and at least a portion of the web of the one plastic component is apart from the web of the other plastic component.
