ABSTRACT:
A cap is formed within the flash of a molded polymeric article. Desirably, the material of the flash, and hence the cap, has the same properties as the molded article. In one embodiment, the molded article is a multi-layer plastic fuel tank having a vapor barrier layer sandwiched between structural and/or adhesive layers and the cap has the same general construction and may be fixed or welded to the fuel tank over an opening through the tank. Advantageously, the cap is formed in the same process used to form the molded article and reduces the scrap or waste material by utilizing a portion of the flash which is removed from the molded article after it is formed. Therefore, the cost and time to produce a molded article and one or more caps is greatly reduced.
