Claims18
A method for forming a blow molded container with a base having a moveable region and a bearing surface, the method comprising:
- receiving a parison;
- enclosing said parison with a mold that includes a cavity;
- inflating said parison, while enclosed in said mold, to form said blow molded container with said moveable region at said cavity;
- and
- after said inflating has been completed, starting repositioning of said moveable region before filling said blow molded container,
- wherein, before said repositioning, at least a first portion of said moveable region of said blow molded container is arranged outwardly below a lower-most extremity of said bearing surface, and at least a second portion of said moveable region of said blow molded container is arranged inwardly above said lower-most extremity of said bearing surface,
- wherein the second portion of said moveable region arranged inwardly above said lower-most extremity of said bearing surface is located at the center of the moveable region of said blow molded container, and
- wherein the first portion of said moveable region arranged outwardly below said lower-most extremity of said bearing surface surrounds the second portion of said moveable region.

A method comprising:
- inflating a parison to form a blow molded container having a moveable region, an opening at a top end of the container and a bearing surface at a bottom end of said container opposite said top end;
- and
- initiating repositioning of said moveable region of said formed blow molded container after completion of said inflating and before filling said blow molded container,
- wherein, before said repositioning, at least a first portion of said moveable region of said blow molded container is arranged outwardly below a lowest point of said bearing surface, and at least a second portion of said moveable region of said blow molded container is arranged inwardly above said lowest point of said bearing surface,
- wherein the second portion of said moveable region arranged inwardly above said lowest point of said bearing surface is located at the center of the moveable region of said blow molded container, and
- wherein the first portion of said moveable region arranged outwardly below said lowest point of said bearing surface surrounds the second portion of said moveable region.
