Abstract:
Es ist ein Preform (1) zur Herstellung von Kunststoffflaschen, insbesondere PET- Flaschen, beschrieben, der einen starren, im wesentlichen länglichen Körper (2) aufweist, der an seinem einen Längsende geschlossen ausgebildet ist. An seinem gegenüberliegenden Längsende grenzt der Körper (2) des Preforms (1) an einen mit einer Ausgiessöffnung (9) versehenen Halsabschnitt (3), der durch einen radial abragenden, flanschartigen Supportring (4) vom Körper (3) getrennt ist und einen radial abragen- den Garantiering (5) sowie Gewindeabschnitte (6) aufweist. Ein an den Supportring (4) angrenzender Abschnitt bildet einen Übergangsabschnitt (7) zum Körper (2) des Preforms (1). Wenigstens ein oder mehrere an den Körper (2) anschliessende Abschnitt(e) des Preforms (1) (Halsabschnitt 3 und/ oder Supportring 4 und/ oder ein an den Supportring 4 angrenzender Übergangsabschnitt 7 zum Körper 2) weist bzw. weisen eine Wandstärke auf, die wenigstens bereichsweise verjüngt ausgebildet ist.
Abstract:
The multilayered preform (1) or multilayered container obtained by biaxially stretching a preform comprises at least one gas-barrier layer (L B ), said gas-barrier layer (L B ) comprising a polyamide and a polyester, wherein the polyester comprises a x%PETI copolymer and/or a y%PETG copolymer, with x and y being at least equal to 5. The multilayered container exhibits high gas barrier performances, in particular oxygen-scavenging properties, and low haze.
Abstract:
The present invention provides a toner bottle having a ring gear whose teeth are not damaged when the toner bottle is handled. The toner bottle (10) comprises a cylindrical bottle (11) with a bottom (12), a cylindrical aperture (15) for supplying toner and a ring gear (18) disposed around the aperture. Since the tip circle diameter of the ring gear is smaller than that of the cylindrical bottle, the teeth of the ring gear do not project beyond the outer surface of the cylindrical bottle. Therefore the teeth of the ring gear do not get damaged easily. A helical concave is formed on the side wall of the cylindrical bottle. When the ring gear is driven to rotate the toner bottle, the toner inside is conveyed by the helical concave and is supplied to an image forming apparatus through the aperture.
Abstract:
The composition exhibits oxygen-scavenging properties and comprises a polyamide, a polyester, and transition metal catalyst. The amount of polyamide is at least 10wt%, and the polyester comprises a x%PETI copolymer and/or a y%PETG copolymer, with x and y being at least equal to 5. The composition is particularly suitable for making a low haze and gas barrier layer in a multilayered packaging article, such a as a rigid container, a film for a package.
Abstract:
A lightweight finish for a hot-fill container uses less material compared to existing hot-fill container finishes. The lightweight finish yields a cost savings while still providing adequate dimensional stability to allow the container to maintain its shape during the hot-fill process.
Abstract:
A plastic container (10) is provided that includes a hollow body portion including a lower supporting base portion (12); a sidewall portion (14) extending upwardly from the base portion (12); and a neck portion (16) extending upwardly from the sidewall portion (14). The neck portion (16) includes a support flange (18) having an upper (20) and lower surface (22), a tamper-evident formation (28), and a dispensing opening (24) at the top of the neck portion (16). In an embodiment, the dispensing opening (24) has an inner diameter that is at least 22 mm, and the vertical distance (X) from the top of the dispensing opening to the lower surface of the support flange (18) is 0.580 inches or less. A preform (40) and method for making a container are also disclosed.
Abstract:
This invention relates to the preform to produce a plastic container for packaging foodstuffs, and especially to blow mould thin-walled containers which can be hermetically closed with a metal lid by double seaming. The preform (1) includes a body (4) and a convex hemispherical bottom (6). The body (4) has a conical shape that flares towards a cylindrical neck (2) surrounded by a flange (3) that terminates in a thickened rim (5). Preferably, the angle (alpha) at which the internal body surface (4) flares towards the cylindrical neck is greater than the angle (beta) at which the external body surface (4) opens upwards, and the thickness (g2) of the cylindrical neck (2) is less than the thickness (g3) of the bottom (6).
Abstract:
Tapping assembly for beverages, comprising a pressure chamber and a pressurising device, wherein the pressure chamber comprises a lid closing off the pressure chamber at least partly, with an opening in said lid, and a container extending with a neck through said opening and a body extending inside said pressure chamber, wherein a first flange extending around the neck lies at a side of the lid facing the pressure chamber and at least one element extending from said neck lies at the opposite side of the lid, the device being provided with at least one closure element engaging said at least one element, forcing said element away from the lid and thereby pulling the first flange towards the lid for sealing the opening by at least the first flange.

Abstract:
The invention concerns a process and a device for producing blow-moulded hollow bodies (11) made of plastic, preferably PET. A cast, hollow, hot preform (11) is placed in a hot blow mould (14) and the material is expanded until its walls adopt the desired shape of the hollow body. Different regions of the wall are subjected to different degrees of expansion, depending on the desired shape of the hollow body. To modify such a process and such a device to produce reusable hollow bodies, it is proposed that, before blow moulding, additional heat be supplied by an additional heater (13) to transition regions (11c) of the wall of the preform between wall regions subjected to different degrees of expansion, in particular between a wall region subjected to little or no expansion and a wall region subjected to greater expansion.
