Abstract

La présente invention concerne un article moulé en résine, auquel on a inséré un film, qui permet de réduire tout dégât sur un film lors d'un moulage par injection, qui permet à une résine fondue de s'écouler librement dans un moule métallique, de réduire toute empreinte à la suite d'un moulage et de retirer facilement tout bossage. L'invention porte sur un article moulé en résine (1), auquel on a inséré un film (4) à des fins de décoration. À la suite du moulage par injection, ledit article comprend, sur la surface inverse opposée à la surface adhésive du film (4), une protubérance (10) résultant du retrait d'une bosse générée lors de l'apport en résine fondue. Ladite protubérance (10) possède une zone transversale supérieure à celle de la bosse et une face inférieure de configuration plane s'étendant suivant une direction ou de configuration radiale et s'étendant alors dans de multiples directions.
