PURPOSE:To obtain a method for manufacturing a synthetic resin product applicable to use in wide range such as container wherein the strength of the whole of the product is increased, by inserting a molded body formed by pulp molding with melted resin and fiber which is mixed and kneaded into a mold and injecting a resin of the same kind so as to form the product. CONSTITUTION:In manufacturing a synthetic resin product, melted resin and fiber are kneaded and a predetermined shape is molded out of it by pulp molding. In a state that the molded body is inserted into a mold of an injection molding machine, a resin of the same kind as the melted resin is injected so as to form a product. A container 1 formed into a box by this manufacturing method is a molded piece molded out of a main body 2 formed into a box by pulp molding. A flange 3 is provided at the top edge of the main body 2. The flange 3 is molded by injection molding and integrated with the main body 2 so as to be jointed firmly, thereby improving the strength of the whole of the container 1. |
