Abstract:
A plural preform assembly (230, 240) including an outer preform (230) and an inner preform (240). The outer preform (230) includes an outer preform open end, an outer preform closed end longitudinally opposed thereto, and an outer preform sidewall joining the outer preform open end and the outer preform closed end. The inner preform (240) may be disposed in the outer preform (230). The inner preform (240) includes an inner preform open end, an inner preform closed end longitudinally opposed thereto, and an inner preform sidewall joining the inner preform open end and the inner preform closed end. The inner preform (240) has an inner preform intrinsic viscosity and the outer preform (230) has an outer preform intrinsic viscosity. The inner preform intrinsic viscosity and the outer preform intrinsic viscosity are different. The plural preform assembly may be blow molded into an article.

Abstract:
A preform (207, 301), and a container (201, 312, 319) blown therefrom in a two stage process (as defined in the specification) is disclosed having a loop (202, 304, 313) defining a handle portion of the resulting blown container and wherein the loop is integrally connected by both a first end (306) and a second end (308) to respective first location (307) and second location (309) of the preform during manufacture of the preform. An injection machine for the manufacture of preforms having integral handles and an injection blow moulding machine incorporating heat insulating means to handle portions of performs is also described.
Abstract:
A cleaning system (10a-10g) comprising a liquid source (12) configured to provide a feed liquid at a first temperature, and an electrolysis cell (18) configured to receive the feed liquid and to electrochemically activate the feed liquid to provide an electrochemically-activated liquid, wherein the electrochemical activation also heats the feed liquid such that the electrochemically-activated liquid is at an elevated temperature that is greater than the first temperature. The cleaning system also includes a dispenser (20) configured to dispense the electrochemically-activated liquid.
Abstract:
A method of producing a tubular article, such as a can body or a bottle, of a biaxially oriented crystallisable thermoplastic polymer such as polyethylene terephthalate from a tubular article of smaller dimensions, such as a preform, having at least one open end, comprises heating the smaller tubular article to a temperature above the glass transition temperature but below the melting temperature of the polymer, stretching the tubular article axially by mechanical means such as an extending push rod (122) or a drawing chuk element, and simultaneously or sequentiall stretching the tubular article both axially and transversely by internal fluid pressure introduced through the open end (13), without any external mould or other external constraint. The stretched and biaxially oriented article (10) may be subsequently heated further to anneal the polymer and thereafter cooled before removal from the stretching apparatus, the internal pressure being reduced during such annealing and cooling. For polyethylene terephthalate, the stretching temperature is from 75oC to 120oC and the internal fluid pressure from 7 to 15 bars, while the annealing temperature is from 110oC to 240oC and the reduced internal fluid pressure used during annealing and/or cooling is from 2 to 4 bars.
Abstract:
Es ist ein Kunststoffbehälter beschrieben, der aus einem Preform mit einem Massenanteil von wenigstens 80% Polyester und gegebenenfalls wenigstens einem Zusatzstoff aus der Gruppe bestehend aus Farbstoffen, Füllstoffen, Katalysatoren, Additiven und Gleitadditiven gefertigt ist. Der Kunststoffbehälter weist einen Behälterhals und eine an den Behälterhals anschliessende Behälterschulter auf, die in einen mit einem Behälterboden verschlossenen Behälterkörper übergeht. Die Behälterschulter, der Behälterboden und der Behälterkörper sind in einem 2-Stufen-Streckblasverfahren ausschliesslich mittels eines Blasverfahrens umgeformt. Das Polyester ist ein Copolyester und weist Gruppen auf, welche von den Monomeren Cyclohexandimethanol (CHDM) und/oder Monoethylenglykol (MEG), Terephtalatsäure (TPA) oder deren Derivate und Isophtalsäure (IPA) oder deren Derivate ab stammen. Wenigstens ein Teilbereich des Behälterkörpers und/oder der Behälterschulter weist eine scharfe Kante mit einem Radius von weniger als 0,5 mm auf. Es ist auch ein Verfahren zur Herstellung des Kunststoffbehälters beschrieben.
Abstract:
A structure including an electro-active-polymer ("EAP"). The structure can take the form of a strap, which includes two or more EAP film layers. The structure can further include one or more holders or end-grabbing portions. Methods of making and using the EAP structure are also envisioned.
