A blow molded container is provided. The container has a base, a body portion attached to the base, a concave waist attached to the body portion, a dome attached to the waist, a plurality of structural ribs, and a finish attached to the dome. The dome has a plurality of panels arranged around a perimeter of the dome. The finish has an opening and a portion of the dome is located between the panels and the waist. Each of the structural ribs is located between two adjacent panels and is raised relative to the panels.
摘要:
A process and a bottle made from this process where the bottle has improved material thickness distribution within the bottom or base portion. The bottle has a noncircular cross-sectional configuration with corresponding major and minor axes. The mold-base region of the bottle mold-cavity features at least one standing rib-like projection generally parallel to the major axis. The standing rib-like projection increases surface distance in a direction generally corresponding with the minor axis. An expanding heated preform traverses the increased surface distance causing the preform to thin more than what otherwise would be the case thus improving material thickness distribution of the base portion that in turn minimizes unwanted bottle shape distortions.

A plastic bottle is disclosed, which comprises a cylindrical sidewall having a predetermined thickness, an upper mouth-forming portion, a neck extending from this mouth-forming portion, a dome-shaped portion between the neck and one axial end of the cylindrical sidewall, a lower bottom-forming base extending from the other axial end of the cylindrical wall, all about a central axis. The bottle also has at least three substantially vertical exterior ribs that are substantially uniformly angularly spaced from each other about the axis on the neck, and these ribs have maximum cross-sectional radial dimensions along the axis generally greater than said predetermined thickness. The ribs reinforced the neck and distribute forces resulting from impact of a localized force to the mouth-forming portion towards the dome-shaped portion and cylindrical sidewall.
摘要:
A plastic hot fill container including a container body, which is integrally formed as one piece with a flange, the flange having a generally cylindrical outer facing wall surface onto which are formed a plurality of typically mutually spaced threading protrusions, the flange being characterized in that it is formed with at least one thickened flange portion located at the region of at least one leading edge of the threading protrusions.
