Abstract:
1. A method for providing a plastic bottle with a deep-set grip in a sidewall of the bottle by injection blow molding, the method comprising: enclosing a parison within a multi-piece mold, the multi-piece mold having a first distinct portion thereof that includes a first wall with a first recess; performing injection blow molding to the parison in the mold to form an injection blow molded plastic bottle, the injection blow molded plastic bottle having a sidewall, a first movable region being formed in the sidewall in correspondence with the first recess of the first wall so that the first movable region extends into the first recess such that corresponding material of the plastic bottle substantially entirely covers a surface area of the first recess, a first hinge circumscribing a first interface between the sidewall and the first movable region, a wall thickness at the first hinge being thinner than immediately surrounding portions of the injection blow molded plastic bottle on both sides of the first hinge; and moving the first movable region toward an interior of the blow molded plastic bottle about the first hinge, said moving occurring before filling the injection blow molded plastic bottle with a product, wherein the first distinct portion of the multi-piece mold is not a deep-set mold with a projection, and after said moving the first movable region toward the interior of the container, the first moveable region is deep-set to form the deep-set grip.
