Plastic container with flattened supporting feet and blow molding device

A plastic container, having a bottom region, a main body adjoining this bottom region in the longitudinal direction of the plastic container, and a mouth region adjoining this main body at least indirectly in the longitudinal direction and having a container mouth, wherein the bottom region has at least three supporting feet which, viewed in the circumferential direction with respect to a central axis of the bottom region extending along the longitudinal direction, each extend over a supporting foot circumferential angle, wherein each of these supporting feet has at least one supporting region extending in the circumferential direction over a supporting region circumferential angle and each having at least one supporting surface for standing the plastic container upright, wherein at least one groove having a groove base acting as a tension band is arranged between two of these supporting feet, the groove base widening outwardly in the radial direction,

• wherein
• each of the at least three supporting feet has at least one flattened region arranged at least partially between the supporting region and the adjacent groove and at least one bulged region arranged between the flattened region and the supporting region, wherein the flattened region is flattened compared to the bulged region with respect to a curvature behavior, wherein the bulged region extends, as viewed in the circumferential direction, at most over half the supporting region circumferential angle and/or at most over one tenth of the supporting foot circumferential angle.

A plastic container having a bottom region, a main body adjoining this bottom region in the longitudinal direction of the plastic container, and a mouth region adjoining this main body at least indirectly in the longitudinal direction and having a container mouth, wherein the bottom region has at least three supporting feet, wherein each of these supporting feet has at least one supporting region extending in the circumferential direction with respect to a central axis of the bottom region extending along the longitudinal direction and each having at least one supporting surface for standing the plastic container upright, wherein at least one groove having a groove base acting as a tension band is arranged between two of these supporting feet, the groove base widening outwardly in the radial direction,

• wherein
• the bottom region is configured such that a bottom line running along the bottom region from a geometric center of the supporting region of a supporting foot to the groove base of the adjacent groove at a constant distance from the central axis has a geometric progression of height values, considered along the central axis, as a function of an angle of rotation measured in the circumferential direction with respect to the geometric center of the supporting region, which angle of rotation, after passing through the supporting region, decreases sharply in such a way that a maximum height value assumed in the supporting region within a line portion, which takes up at most 30% of an angle of rotation between the geometric center of the supporting region and the geometric center of the groove base of the adjacent groove, is reduced by at least 8% with respect to a maximum height difference of the bottom line.
