Hollow plastic article formed by a gas-assisted injection molding system |
摘要 |
A hollow plastic article of a one-piece construction formed from a molten plastic resin by a gas-assisted injection molding system wherein the article is designed in such a way that any gas channel read through is hidden at a "Class A" convex surface thereof. The article includes a hollow body section and a solid wall section which extends downwardly and rearwardly from a front wall of the hollow body section. The solid wall section and the front wall immediately adjacent to the solid wall section define a convex, sink-free, exterior surface of the article to hide any gas channel read through.
