Method of Forming Container

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 oldie 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.

A method for making a blow molded plastic container with at least one deep-set grip, the method comprising:

• providing a plastic preform;
• positioning the preform with respect to a container forming apparatus, the container forming apparatus having at least one recess, the number of said at least one recesses corresponding to the number of at least one deep-set grips:
• inflating the preform to form a plastic container in an intermediate configuration with at least one projection extending outwardly therefrom in correspondence with the number of said at least one recesses of the container forming apparatus;
• and
• repositioning each said at least one projection inwardly into an inner volume of the intermediate container configuration to form a final container configuration.
