Abstract: A co-injection hot runner nozzle comprises an inner melt flow channel and an annular outer melt flow channel that surrounds the inner melt flow channel. The inner and outer melt flow channels have a first common source. The nozzle further comprises an annular intermediate melt flow channel disposed between the inner and outer melt flow channels. The annular intermediate melt flow channel is at least partly defined by a plurality of spiral grooves, each spiral groove having a respective inlet and defining a helical flow path. Lands between adjacent spiral grooves increase in clearance in a downstream direction. An annular axial flow path is defined over the lands. A plurality of feeder channels having a second common source is configured to supply melt to the plurality of inlets of the spiral grooves. The relationship of feeder channels to spiral grooves may be one-to-one. The inlets may be longitudinal channels.

Abstract: A molded article suitable for subsequent blow-molding into a final-shaped container. The article includes a neck portion; a gate portion; and a body portion extending between the neck portion and the gate portion, at least a majority of the body portion having an overall shape which is symmetric about a body axis extending longitudinally through a center of the body portion. The body portion includes an inner exterior layer and an outer exterior layer of a first polymeric material; and a core layer of a second polymeric material disposed between the inner exterior layer and the outer exterior layer. A radial thickness or a material of the core layer is selectively varied to govern non-uniform blow molding of the molded article into the final-shaped container.

Abstract: A preform is provided for blow-molding to form a container. The preform includes a finish portion for rotatably engaging a closure to seal contents within an interior of the container. The finish portion comprises a cylindrical body that begins at an opening to the interior and extends to and includes a tamper evidence ledge. A mirror polished sealing surface inside the finish portion cooperates with a plug seal of the closure to seal the container. Threads outside the finish portion engage with similar threads inside the closure. Thread starts of the threads reduce potential damage to the threads during installation of the closure. The thread starts may include a start pitch that is greater than a thread pitch of the threads. A handling valley disposed between the threads and the tamper evidence ledge facilitates air-conveying the container along a manufacturing assembly line.

Abstract: The invention relates to a preform for producing a plastic container in a blow moulding method, comprising an elongated, preform body, which is formed so as to be closed at the one longitudinal end thereof and, at the other longitudinal end thereof, has a neck section having a pouring opening. The preform is produced from recycled PET and aliphatic furanoate, wherein the recycled PET has a maximum of 2.5 wt % of isophthalic acid and diethylene glycol, wherein the proportion of isophthalic acid is no higher than 2.0 wt %, and the proportion of diethylene glycol is no higher than 2.0 wt %, wherein all the percentages by weight are based on the total weight of the preform. Turbidity of the preform, measured in accordance with ASTM D I 003-00, is less than 5%, as a result of the admixture of the aliphatic furanoate.

Abstract: Disclosed are preforms which incorporate improvements in the region of the neck and upper segment of the body to allow the production of lightweight containers, such as bottles suitable for containing water or other beverages. In accordance with certain embodiments, the improvements include a thinner neck finish area than conventional bottles, where the thinner area is extended into the upper segment of the body portion below the support ring. Reducing the thickness in these areas of the bottle allows for less resin to be used in forming the preform and bottle.

Abstract: A method for injection molding a preform includes: a) loading a barrier membrane into a first mold cavity; b) injecting melt into the first mold cavity to undermold the barrier membrane and form a preform inner layer on an inside of the barrier membrane; c) moving the preform inner layer and the barrier membrane from the first mold cavity into a second mold cavity; and d) injecting melt into the second mold cavity to overmold the barrier membrane and form a preform outer layer on an outside of the barrier membrane. Preforms formed by the method and an injection molding machine to carry out the method are also disclosed.
