Method and device for producing and filling containers
An apparatus for transforming a preform into a container filled with liquid filling material includes a mold that forms a mold head, a sterilization system, a chamber that is common to a group of mold heads, an evacuation system that is connected to the chamber, and conduit lines, each of which connects a mold head to the chamber. The sterilization system sterilizes the interior of the preform while it is in sealing engagement with the mold head. The evacuation system creates a vacuum in the preform. Liquid filling material enters the preform under pressure and causes it to transform into a container.
METHODS OF MANUFACTURING NESTED BALLOONS UTILIZING PRESSURIZED CONSTRAINED ANNEALING
A nested balloon is provided where each balloon is formed from tubing that optimizes the inner wall stretch thus providing maximum balloon strength. The high pressure, nested balloon is provided with layers that allow for slipping, such that the balloon has a very high pressure rating and toughness, yet excellent folding characteristics. Methods for producing such nested balloons using existing balloon forming equipment are also provided. The nested balloons can have layers with low-friction surfaces. The nested balloons are preferably manufactured using a variety of methods, including pressurized constrained annealing.
MOLDED FOAM
The present invention relates to molded foam having no hollow space caused in a plate-shaped portion. The molded foam comprises a tube body and a plate-shaped portion joined to the outer side of the tube body. The expansion ratio of the molded foam is lower than two, and a value of a thickness B/a thickness A as a relationship between the thickness A of the tube body at the periphery of a point joined to the plate-shaped portion and the thickness B of the plate-shaped portion is less than 2.82.
Refillable polymer bottle and method for improved caustic stress crack resistance
This disclosure provides new methods, compositions, containers, preforms, and designs for refillable carbonated soft drink bottles having improved caustic stress cracking resistance. The method of this disclosure combine the use of PET-based co-polyester resin that incorporates a cyclic hydrocarbon diacid co-monomer and/or a cyclic hydrocarbon diol comonomer, with a bottle design incorporating a petaloid base, for unexpectedly enhanced performance.
Chamber for storing build material
Examples of the present disclosure relate to a container. The container has a chamber for storing build material for a three-dimensional printing system. The container comprises an opening coaxial with the chamber for coupling to the three-dimensional printing system. The container is configured such that rotation of the chamber in a first direction conveys build material in the chamber to the three-dimensional printing system and rotation of the chamber in a second direction conveys the build material away from the three-dimensional printing system.
Method for Manufacturing a Polymer Article
A method enabling the selection, modification and/or creation of polymer materials which can provide improved response to the application of local shear and/or extensional deformation inside the polymer melt in manufacturing technologies including injection molding, injection stretch blow molding, direct injection, extrusion blow molding, sheet extrusion, thermoforming, etc., is provided. A method for manufacturing a polymer article includes injecting or extruding molten polypropylene, polyethylene or polyester based polymer for converting it into semi-final shape while applying shear and/or extensional deformation on the polymer melt. Applying shear and/or extensional deformation on the polymer melt includes selectively modifying the flow path of the molten semi-crystallizable polymer as a function of local pressure profile over at least part of the flow path. Local pressure profile is a function of optimized response of the polymer melt to the applied local shear and/or extensional deformation over at least the part of the flow path.
Table
A molded plastic structure may comprise a tabletop with an upper surface and a lower surface. A lip may extend downwardly relative to the lower surface of the tabletop, and the lip may include an outer surface and an inner surface. An inwardly extending portion may extend inwardly from the inner surface of the lip. A frame may be connected to the table top and the frame may include a side rail of a frame. The side rail may include a receiving portion that receives the inwardly extending portion. The side rail may also include a portion that supports the lower surface of the table top and a portion that supports the lip.

TWO-PART MASTERBATCH, PACKAGING ARTICLES, AND METHODS
A two-part masterbatch comprising: a first part comprising an unsaturated thermoplastic polymer, wherein the first part (typically, the unsaturated thermoplastic polymer of the first part) has an iodine value of at least 10; and a second part comprising an oxygen scavenging catalyst; packaging articles (e.g., preforms and plastic containers), and methods.
Molded plastic structures
A plastic molded lip structure may extend along a perimeter of a planar element and may include an outer wall, an inner wall, structural portions, and protruded features. The outer wall may extend in a normal direction from the planar element. The inner wall may be disposed in an inward direction relative to the outer wall. The structural portions may be disposed along structural sections of the perimeter and may include first portions of the inner wall and of the outer wall. The first portions may be disposed parallel to the inner wall and separated from the first portions by a first distance along the structural sections. The protruded features may be interposed between two structural portions and an inner wall may be separated from second portions of the outer wall by a second distance that is greater than the first distance.
