A container comprising: an open end circumscribing a longitudinal axis; and a peripheral wall extending from said open end about said longitudinal axis to a closed end; wherein said peripheral wall and said closed end comprise a thermoplastic material; wherein said peripheral wall comprises a faceted region comprising a plurality of facets arranged edge to edge with at least one adjacent facet, at least a portion of said faceted region being located nearer to said closed end than to said open end; wherein said peripheral wall has a peripheral wall exterior surface oriented away from said longitudinal axis, said peripheral wall exterior surface having a peripheral wall exterior surface area; wherein each of said plurality of facets has a facet exterior surface oriented away from said longitudinal axis and each of said facets has a facet exterior surface area that is between 0.0001% and 4% of said peripheral wall exterior surface area; wherein at local positions along said longitudinal axis said container has a local maximum internal dimension orthogonal to said longitudinal axis, a local major axis coincident with said local maximum internal dimension, a local minor axis orthogonal to said local major axis and said longitudinal axis, a local minor internal dimension coincident with said local minor axis, and a local aspect ratio defined as a ratio of said local maximum internal dimension to said local minor internal dimension; wherein said peripheral wall is free from said facets above a location along said longitudinal axis at which said aspect ratio is between about 1 and about 1.1; characterized in that individual said facets have a radius of curvature of the principal curvatures at a centroid of said facets greater than 60 mm. an open end circumscribing a longitudinal axis; and a peripheral wall extending from said open end about said longitudinal axis to a closed end; wherein said peripheral wall and said closed end comprise a thermoplastic material; wherein said peripheral wall comprises a faceted region comprising a plurality of facets arranged edge to edge with at least one adjacent facet, at least a portion of said faceted region being located nearer to said closed end than to said open end; wherein said peripheral wall has a peripheral wall exterior surface oriented away from said longitudinal axis, said peripheral wall exterior surface having a peripheral wall exterior surface area; wherein each of said plurality of facets has a facet exterior surface oriented away from said longitudinal axis and each of said facets has a facet exterior surface area that is between 0.0001% and 4% of said peripheral wall exterior surface area; wherein at local positions along said longitudinal axis said container has a local maximum internal dimension orthogonal to said longitudinal axis, a local major axis coincident with said local maximum internal dimension, a local minor axis orthogonal to said local major axis and said longitudinal axis, a local minor internal dimension coincident with said local minor axis, and a local aspect ratio defined as a ratio of said local maximum internal dimension to said local minor internal dimension; wherein said peripheral wall is free from said facets above a location along said longitudinal axis at which said aspect ratio is between about 1 and about 1.1; characterized in that individual said facets have a radius of curvature of the principal curvatures at a centroid of said facets greater than 60 mm.
