PURPOSE: A producing method of a foldable plastic container using a hollow molding mode is provided to reduce a separate assembling process, and to form a mold into a rhombus shape for easily storing. CONSTITUTION: A producing method of a foldable plastic container(1) comprises the following steps: inserting an injection hole(7) before closing a mold for molding; holding a parison using a fixture installed on the upper side of an elongation unit; pulling the parison by moving the elongation unit to the lower side; and thinly producing an injection-molded product by inserting air into an air vent inside the mold.
