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.

A preform including: an opening portion; a body portion; and a bottom portion, the preform having a two-layer structure in which the body portion and the bottom portion include an inner layer made of a virgin material and an outer layer made of a recycled material, in which a weight ratio of the recycled material to a total weight of the preform is 50% by weight or more, a ratio of a thickness of the outer layer to a thickness of the inner layer in the body portion is 1.5 or more, and a haze of a body portion of a container molded from the preform is 1.8% or less.

This disclosure provides new methods to characterize and relate residual stress and orientation imparted to the injection molded polymeric preform with orientation and residual stress in the resulting blow molded bottle. The method developed allows one to define and map the coupled thermal stress histories of both processes to define applicable preferred mutual processing windows for both preform and bottle molding processes. Stretch blow-molding parameters are developed using the disclosed method.

A continuously rotating, non-symmetric preform feed, stretch-blow-moulding machine dedicated to the stretch-blow-moulding of containers from non-symmetric injection moulded preforms; the non-symmetric preforms including an integral handle extending from a first junction point to a second junction point on a body of the preform; the body of the preform and the integral handle constituted from the same material.

A production method for a container having a covering layer includes forming a preform having a covering layer by using a thermoplastic synthetic resin; heating the preform from an outside of the preform with an infrared heater, and heating the preform from an inside of the preform with an internal heating unit; and forming the container having the covering layer by blow molding in which the heated preform is blown.

A method for manufacturing a resin container, the method including: injection-molding a bottomed preform made of resin; and blow-molding the preform to manufacture a resin container, in which the injection molding includes filling a cavity formed by at least an injection core mold and an injection cavity mold with a molten resin to form the preform, and a first groove that extends from a bottom portion defining portion to a neck portion defining portion is formed in a surface of the body portion defining portion of the injection core mold.

A device produces at least one container product made of plastics material, which is molded by a molding device (1). The container product is filled with a predefinable container content by a filling device and closed by a closing device. The finished container product is fed to a post-treatment zone in which the container product and/or the respective container content is subjected to a temperature-influencing effect.

Apparatus for producing containers, and in particular beverage containers, having a heating device configured to heat plastic parisons, having at least one first transport device, which transports the plastic parisons along a predetermined transport path, a sterilization device configured to sterilize the plastic parisons, and a forming device arranged downstream of the sterilization device, as seen in a transporting direction of the plastic parisons, and configured to form the plastic parisons into plastic containers by the application of a free-flowing medium, wherein said forming device has a transport chamber within which the plastic parisons are transported. The apparatus has an application device configured to apply a free-flowing sterilization medium, at least temporarily, to the transport chamber.
