Abstract: A packaging assembly for lightweight containers that includes a secondary packaging for gathering and holding a plurality of individual primary lightweight containers. The secondary packaging includes two layers of thermoplastic shrinkable film enclosing the lightweight containers, with the layers being connected to one another at least partially in the circumference of the secondary packaging. Each of the primary lightweight containers has a container body and a container neck with a neck opening. The lightweight containers are disposed in the secondary packaging in rows forming one single, substantially plane layer, with all containers being oriented with their longitudinal axis (L) forming an angle (?) with the plane of the packaging assembly that is between 0 and 45°.

Abstract: Air cartridge devices and methods of using the air cartridge devices are provided. In an embodiment, the present disclosure provides an air cartridge device comprising an elongated cylindrical shaft defining a first elongated end portion and a second elongated end portion. The second elongated end portion can defining one or more apertures. The air cartridge device can be incorporated into a blow molding apparatus for blow molding bottles.

Abstract: Heat is extracted from compressed gas used in a blow-molding process by expansion cooling the exhausted gas and/or passing the exhausted gas through a vortex tube, which supplies cold gas at an exit thereof. The cold gas is then routed through cooling channels in the mold. This obviates the need for recirculating or externally chilling a coolant and saves energy.

Abstract: The invention relates to a secondary package for gathering a plurality of primary packages, comprising an envelope that surrounds the plurality of primary packages so as to tightly hold the latter together. The secondary package also includes a base supporting the primary packages, lateral sides, and a top side, characterized in that: (i) said base comprises a medium folding line that pivotally connects two halves of the base supporting the primary packages, and the envelope further comprises a carrying handle that is disposed vertically along the medium folding line, and (ii) the lateral sides and the top side of the envelope comprise a transversal precut in the region of the medium folding line, and so that when the envelope is open along said precut, it still holds tightly the primary packages disposed on each of the two base halves and said halves can be pivoted around the medium folding line to allow complete access to the carrying handle.

Abstract: The present invention is related to a method for the direct production of polyester articles for packaging purposes, in particular for the production of hollow bodies, thermoformed sheets and films, said articles containing an amount of acetaldehyde less than 10 ppm. This method is characterised in that it essentially comprises a step in which the initial level SE0 of the sum of end groups in the polymer melt is increased by adding a mixture of at least one inert and at least one reactive substance to said polymer melt to a second level SE1 and a degassing step consisting in essentially applying a vacuum to the previously obtained polymer melt to cause a removal of low molecular weight substances present and formed, of non reacted reactive substance(s) and inert substance(s) added during previous step before the so obtained polymer melt is directly converted into the desired articles.

Abstract: Method of producing a polyester resin container, such as a PET bottle, from a preform (10) includes a step whereby the preform (10) is heated to a temperature above a glass-transition temperature and a drawing step which is performed in a cavity (101). According to the invention, during the drawing step, an incompressible fluid and not a gaseous fluid is injected through the opening in the preform (10?).

Abstract: The present invention relates to a container (2) comprising a body (23), a neck (22) and a closure element (21), the said body having a surface of positive curvature and including, on its external surface, a stretch film (1) partially covering its surface, made of a plastic different from or the same as that of the body of the said container.

Abstract: The invention concerns the field of manufacture of PET containers designed in particular for packaging food products, particularly bottles for aerated beverages such as in particular natural and mineral water. The method for manufacturing PET resin preforms and the resulting preforms, a method for making PET resin containers from the preforms and the manufactured containers, in particular food bottles made of PET resin. The method for making PET resin preforms is characterised in that it consists in using a PET resin having an intrinsic viscosity (IV) less than 0.65 dl/g.

Abstract: A valve assembly has a valve housing and a valve core body movable therewithin for providing a smooth and continuous outflow of liquid from a container, which may be unvented and rigid, through a liquid-out passageway, and provides an air-back passageway for drawing external air into the container. In a preferred embodiment, the core is rotatable within the housing by one-handed actuation. The air-back passageway is preferably a channel provided on the surface of the core body, and the liquid-out passageway is preferably provided between openings in the core body.

Abstract: The present invention relates to a container for a flowable product, particularly for a beverage and, in particular, for still or sparkling mineral water. The container according to the invention includes a body having in a greater section a dimension d1 and of at least one neck with an internal diameter d2 which can be closed by a member for closing off and/or of distributing the flowable product from the container. The wall or walls forming the body of the container are preferably made of a flexible plastic which can deform for constant surface area, particularly under the weight of the flowable product from the container when the wall or walls encounter a point or bearing surface, so as to form, at least locally, a non-planar wall portion and wherein the ratio d2 to d1 is between 1:3 and 1:10.

Abstract: The invention concerns polyester resins, more particularly polyethyleneterephthalate resins used for making hollow containers, such as bottles for packaging liquid substances, in particular aerated beverages, natural or mineral waters. The invention concerns a polyester comprising at least 92.5% in number of recurrent units derived from terephthalic acid of aliphatic diols having an intrinsic viscosity ranging between 0.45 dl/g and 0.70 dl/g, and an acetaldehyde content less than 3 ppm, preferably less than 1.5 ppm. The invention also concerns a method for obtaining polyester granules with low acetaldehyde content having an intrinsic viscosity in the range mentioned above. Said polyesters are used in particular for making hollow containers such as bottles and more particularly bottles designed to contain foodstuffs sensitive to acetaldehyde.
