1. A container forming assembly for forming from a parison a container having an inverted deep-set gripping region, the container having a first movable gripping region, the first movable gripping region being the inverted deep-set gripping region, the container forming assembly comprising: a mold having a wall without a deep protrusion and with a recess adapted to receive a portion of the parison in response to inflation thereof, the recess having a first forming portion adapted to form a first portion of the first movable gripping region and a second forming portion adapted to form a second portion of the first movable gripping region, wherein said first portion is rotatable about a first hinge toward an interior of the container, and said second portion is rotatable about a second hinge toward the interior of the container;a drive mechanism adapted to move said mold to enclose the parison during blow molding and to release the container after blow molding; andmeans for moving inwardly the first movable gripping region. 2. The container forming assembly according to claim 1, wherein said means for moving inwardly the first movable gripping region includes: a first push rod operative to rotate said first portion about said first hinge before filling the container; anda second push rod operative to rotate said second portion about said second hinge before filling the container. 3. The container forming assembly according to claim 1, wherein the mold includes a first mold half adapted to form the first movable gripping region and a second mold half adapted to form a second movable gripping region, said second movable gripping region having first and second hinges, first and second rotatable portions, and the structure of the first movable gripping region. 4. The container forming assembly according to claim 3, wherein the first and second movable gripping regions are formed in the container so that a consumer's hand easily fits into the inverted gripping regions. 5. The container forming assembly according to claim 3, wherein each of said first and second mold halves comprise: a movable gripping portion forming region including:a first surface adapted to form a first outer grip portion of said movable gripping region;a second surface adapted to form a second outer grip portion of said movable gripping region;a third surface adapted to form a first inner grip portion of said movable gripping region;a fourth surface adapted to form a second inner grip portion of said movable griping portion; anda fifth surface area adapted to form a ridge area of said movable gripping portion. 6. The container forming assembly according to claim 5, wherein said fifth surface area is positioned between said third and fourth surfaces, and wherein said third and fourth surfaces are positioned adjacent to said first and second surfaces, respectively. 7. The container forming assembly according to claim 1, wherein said mold includes one or more vacuum panel forming portions, each of said one or more vacuum forming portions being arranged in a location of said mold different from the recess thereof. 8. The container forming assembly according to claim 1, wherein the first movable gripping region is formed at a base of the container. 9. The container forming assembly according to claim 1, wherein said means for moving inwardly the first movable gripping region is operative to act on the first movable gripping region to cause movement inward of the first movable gripping region so as to reduce an internal volume of the container. 10. The container forming assembly according to claim 1, wherein the recess of said mold is arranged in a side mold portion thereof. 11. The container forming assembly according to claim 1, wherein the recess of said mold is arranged in said mold so as to form a base portion of the container. 12. The container forming assembly according to claim 1, wherein the container forming assembly is operative to invert the first movable gripping region to make the inverted deep-set gripping region of the container while the container is fully enclosed within said mold. 13. The container forming assembly according to claim 1, wherein the recess is adapted to form the first hinge, a wall thickness at the first hinge being thinner than immediately surrounding portions on both sides thereof. 14. A container forming assembly for forming from a parison a container, the container having a first movable gripping region, the container forming assembly comprising: a mold having a wall with a recess adapted to receive a portion of the parison in response to inflation thereof, the recess having a first forming portion adapted to form a first portion of the first movable gripping region and a second forming portion adapted to form a second portion of the first movable gripping region, wherein said first portion is rotatable about a first hinge toward an interior of the container, and said second portion is rotatable about a second hinge toward the interior of the container;a drive mechanism adapted to move said mold to enclose the parison during blow molding and to release the container after blow molding; andmeans for moving inwardly the first movable gripping region. 15. The container forming assembly according to claim 14, wherein the mold includes a first mold half adapted to form the first movable gripping region and a second mold half adapted to form a second movable gripping region, said second movable gripping region having first and second hinges, first and second rotatable portions, and the structure of the first movable gripping region. 16. The container forming assembly according to claim 14, wherein said mold includes one or more vacuum panel forming portions, each of said one or more vacuum forming portions being arranged in a location of said mold different from the recess thereof. 17. The container forming assembly according to claim 14, wherein the recess of said mold is arranged in a side mold portion thereof. 18. The container forming assembly according to claim 14, wherein the recess of said mold is arranged in said mold so as to form a base portion of the container. 19. The container forming assembly according to claim 14, wherein the container forming assembly is operative to invert the first movable gripping region to make an inverted deep-set gripping region of the container while the container is fully enclosed within said mold. 20. The container forming assembly according to claim 14, wherein the recess is adapted to form the first hinge, a wall thickness at the first hinge being thinner than immediately surrounding portions on both sides thereof.
