An apparatus for forming a blow-molded container includes a mold, a mandrel, and a die. The mold includes a bottom section for forming a container bottom, a sidewall section for forming a plurality of sidewalls, a spout section for forming a spout, and a neck section for forming an upwardly converging neck member coupling the sidewalls to the spout having a convex radius transition section of approximately three inches in a container having an overall height of approximately ten inches. The mandrel and the die are operative to form a parison that assumes an ovoid cross-section within the mold with the outer surfaces of the parison positioned approximately equidistant from sidewall section of said mold.

1. An apparatus for forming a blow-molded container, comprising: a mold including: a bottom section for forming a container bottom,a spout section for forming a spout,a handle section for forming a handle,a neck section for forming an upwardly converging neck member, anda sidewall section for forming a plurality of sidewalls, including a first pair of spaced-apart sidewalls, a second pair of spaced-apart sidewalls, a third pair of spaced-apart sidewalls that define a length for the container in a first direction that extends from the handle section toward the neck section, and a fourth pair of spaced-apart sidewalls that define a width for the container in a second direction that is perpendicular to the first direction, the length of the container being greater than the width of the container, wherein the neck section defines a convex radius transition from the sidewalls to the spout; anda mandrel and a die operative to form a parison that assumes an ovoid cross-section within the mold with an outer surface of the parison positioned approximately equidistant from sidewall section of said mold. 2. The apparatus of claim 1, wherein the mandrel is positioned within an opening of the die to define an annular opening between the opening of the die and the mandrel, and the annular opening widens at an angle of about 15°-18° from a narrow end of said annular opening distal to said mold to a widened end of said annular opening proximal to said mold, wherein the annular opening is operable to receive a liquefied thermoplastic material for forming the parison within the mold. 3. The apparatus of claim 1, wherein the neck section forms the convex radius transition from a sidewall upper limit defined by at least two sidewalls from the plurality of sidewalls to the spout to provide a smooth transition between the at least two sidewalls and the spout. 4. The apparatus of claim 1, wherein the mold is a two piece mold. 5. The apparatus of claim 1, wherein the mold is a three piece mold. 6. An apparatus for forming a blow-molded container, comprising: a mold including: a bottom section for forming a bottom member for the blow-molded container,a sidewall section for forming a plurality of long sidewalls, a plurality of short sidewalls, and a sidewall upper limit for the blow-molded container, each long sidewall of the plurality of long sidewalls being substantially planar, the plurality of long sidewalls including a first pair of opposing parallel sidewalls and a second pair of opposing parallel sidewalls, each short sidewall from the plurality of short sidewalls being disposed between an adjacent pair of long sidewalls from the plurality of long sidewalls, the plurality of short sidewalls including a third pair of sidewalls that are spaced apart by a length of the container, and a fourth pair of sidewalls that are spaced apart by a width of the container, the length of the container being greater than the width of the container, and the sidewall upper limit being defined by one or more long sidewalls from the plurality of long sidewalls and one or more short sidewalls from the plurality of short sidewalls,a spout section for forming a spout, anda neck section for forming a radius transition between the sidewall upper limit and the spout to provide a smooth transition between the sidewall upper limit and the spout; anda mandrel and a die operative to form a parison that assumes an ovoid cross-section within the mold with an outer surface of the parison positioned approximately equidistant from the sidewall section of said mold. 7. The apparatus of claim 6, wherein the spout section is positioned for forming the spout along a central vertical axis of the mold and the die and mandrel are positioned along the central vertical axis of the mold. 8. An apparatus for forming a blow-molded container, comprising: a two or more piece mold including: a bottom section for forming a container bottom,a sidewall section having a plurality of sidewall surfaces for forming a plurality of long sidewalls, a plurality of short sidewalls, and a sidewall upper limit, each long sidewall of the plurality of long sidewalls being substantially planar, the plurality of long sidewalls including a first pair of opposing parallel sidewalls, and a second pair of opposing parallel sidewalls, each short sidewall from the plurality of short sidewalls being disposed between an adjacent pair of long sidewalls from the plurality of long sidewalls, the plurality of short sidewalls including a third pair of opposing parallel sidewalls that define a length of the container and a fourth pair of opposing parallel sidewalls that define a width of the container, the length of the container being greater than the width of the container, and the sidewall upper limit extending along one or more long sidewalls from the plurality of long sidewalls and one or more short sidewalls from the plurality of short sidewalls,a spout section for forming a spout, anda neck section for forming an upwardly converging neck member coupling the sidewalls to the spout having a convex radius transition that is formed between the sidewall upper limit and the spout to provide a smooth transition between the sidewall upper limit and the spout;a die having an opening; anda mandrel, wherein the mandrel is positioned within the opening of the die and is spaced from the die by a die gap of about 0.006 inches to define an annular opening between the opening of the die and the mandrel, and the annular opening widens at an angle of about 15°-18° from a narrow end of said annular opening distal to said mold to a widened end of said annular opening proximal to said mold, wherein the annular opening is operable to receive a liquefied thermoplastic material for forming a parison within the mold. 9. An apparatus for forming a blow-molded container, comprising: a two or more piece mold including: a bottom section for forming a container bottom,a sidewall section having a plurality of sidewall surfaces for forming a plurality of long sidewalls, a plurality of short sidewalls, and a sidewall upper limit, each long sidewall of the plurality of long sidewalls being substantially planar, the plurality of long sidewalls including a first pair of opposing parallel sidewalls, and a second pair of opposing parallel sidewalls, each short sidewall from the plurality of short sidewalls being disposed between an adjacent pair of long sidewalls from the plurality of long sidewalls, the plurality of short sidewalls including a third pair of opposing parallel sidewalls that define a length of the container and a fourth pair of opposing parallel sidewalls that define a width of the container, the length of the container being greater than the width of the container, and the sidewall upper limit extending along one or more long sidewalls from the plurality of long sidewalls and one or more short sidewalls from the plurality of short sidewalls,a spout section for forming a spout, anda neck section for forming an upwardly converging neck member coupling the sidewalls to the spout having a convex radius transition that is formed between the sidewall upper limit and the spout to provide a smooth transition between the sidewall upper limit and the spout;a die having an opening; anda mandrel, wherein the mandrel includes an air passage for inflating the parison. 10.
