Title
(EN) MOULDED PLASTICS ARTICLES
(FR) ARTICLES MOULES EN PLASTIQUE
Abstract
(EN) The invention relates to a food container in the form of a dish made of partly crystalline P.E.T., in which the P.E.T. has different degrees of crystallisation in different regions, so that parts of the containers are selectively hardened while others remain relatively flexible and less frangible upon impact. The mould (30) for moulding the article includes heaters (38) and thermal barriers (36) or cooling passages (40) so that the article is heated to different temperatures and the degree of crystallinity is varied from one region in the container to the other so that some parts remain amorphous and flexible while other parts are hardened by crystallisation.
(FR) La présente invention se rapporte à un récipient pour aliments qui a la forme d'un plat fabriqué à partir de poly(éthylène téréphtalate) partiellement cristallin, le poly(éthylène téréphtalate) présentant différents degrés de cristallisation dans différentes régions, de sorte que certaines parties du récipient subissent un durcissement sélectif alors que d'autres parties restent relativement flexibles et moins cassables en cas de choc. Le moule (30) servant à mouler l'article comprend des organes chauffants (38) et des barrières thermiques (36) ou des passages de refroidissement (4), ce qui permet de chauffer l'article à différentes températures et de faire varier le degré de cristallinité d'une région à l'autre du récipient. Ainsi, certaines parties restent amorphes et flexibles alors que d'autres parties sont durcies par la cristallisation.
