Abstract
A fluid container having a proximal end having an end wall, a distal end having an open-ended neck, and a sidewall extending between the proximal end and the distal end along a longitudinal axis is described. A localized crystallinity of a polymeric material of the fluid container of at least a first region of the fluid container is greater than a crystallinity of a polymeric material of the fluid container of at least a second region. Examples of fluid containers include medical fluid containers, such as medical bottles and syringes, including rolling diaphragm-type syringes, and commercial beverage containers Articles of manufacturer formed form a polymeric material and having regions with increased localized polymeric crystallinity are also described.
