The present invention concerns a container having a body formed by wall or walls with a greater diameter Sand at least a neck with a diameter S, container made from a semi-crystalline PET, having a wall thickness of less than 100 &#x3bc;m, substantially in the middle of its body and having a complex, three dimensional shape convenient for gripping, this part having a diameter S

Container for product with thin wall

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

Method of producing a polyester resin container and device for performing same

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.

Methods for making polyethylene terephthalate (PET) preforms and containers such as food bottles, containers and intermediate preforms obtained

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 dand of at least one neck with an internal diameter dwhich 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 dto dis between 1:3 and 1:10.

Container for a flowable product, process of manufacture and the use thereof

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.
