A container forming assembly and method includes receiving a parison within a cavity of a mold, enclosing the parison within the mold having a wall with a recess, inflating the parison in the mold to form a blow molded container where the blow molded container has a sidewall, a movable region formed at the recess, and a hinge circumscribing an interface between the sidewall and the movable region, and moving or repositioning the movable region toward an interior of the blow molded container about the hinge before filling. The movable region can form a deep-set grip. Further, multiple movable regions can be provided, each of which may form respective deep-set grips. The container shape can be symmetrical or asymmetrical.

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; andmoving 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. 2. The method according to claim 1, wherein the deep-set grip is a deep-set handle. 3. The method according to claim 1, wherein said movement of the movable region toward the interior is performed in a one-step process. 4. The method according to claim 1, wherein the sidewall of the plastic bottle further includes a second deep-set grip,wherein the multi-piece mold has a second distinct portion thereof that includes a second wall with a second recess,wherein said performing injection blow molding to the parison in the mold to form an injection blow molded plastic bottle forms a second movable region in the sidewall in correspondence with the second recess of the second wall so that the second movable region extends into the second recess such that corresponding material of the plastic bottle substantially entirely covers a surface area of the second recess, a second hinge circumscribing a second interface between the sidewall and the second movable region, a wall thickness at the second hinge being thinner than immediately surrounding portions of the injection blow molded plastic bottle on both sides of the second hinge; andmoving the second movable region toward an interior of the blow molded plastic bottle about the second hinge, said moving occurring before filling the injection blow molded plastic bottle with a product,wherein the second distinct portion of the multi-piece mold is not a deep-set mold with a projection, and after said moving the second movable region toward the interior of the container, the second moveable region is deep-set to form the second deep-set grip. 5. The method according to claim 4, wherein said moving the first movable region is in a first direction, and said moving the second movable region is in a second direction, the first direction being opposite to the second direction. 6. The method according to claim 4, wherein the first deep-set grip and the second deep-set grip are arranged centrally about the sidewall in a longitudinal or height direction of the plastic bottle. 7. The method according to claim 1, wherein said performing injection blow molding to the parison in the mold forms one or more vacuum panels, each of the one or more vacuum panels being distinct from first movable region. 8. The method according to claim 1, wherein the first movable region has a plurality of surfaces, and said moving the first movable region causes the surfaces to fold in relation to one another such that the first movable region is inverted to form the deep-set grip. 9. The method according to claim 1, further comprising transporting the container to a location remote from the location at which said performing injection blow molding is performed; filling the formed, plastic bottle with a product; and sealing the filled plastic bottle. 10. 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; andrepositioning each said at least one projection inwardly into an inner volume of the intermediate container configuration to form a final container configuration. 11. The method according to claim 10, wherein the at least one projection and corresponding deep-set grip are at a first portion of the sidewall of the container, and a second portion of the sidewall of the container is without any deep-set grips. 12. The method according to claim 10, wherein the at least one deep-set grip includes at least two of said deep-set grips, the at least two deep-set grips being on opposite sides of the container so as to form a deep-set handle.
