Abstract

Un procédé de fabrication d'objets en verre moulés en forme de boîte comprend les étapes suivantes: on préforme du verre jusqu'à une température supérieure ou égale au point de transition vitreuse sous forme de boîte au moyen d'un moule; on réalise un support dans une matière ou une structure contenant à l'intérieur un agent filmogène vapeur qui n'est pas gazeux au moins dans des conditions de température ambiante mais qui est effectivement gazeux à une température égale ou supérieure au point de transition vitreuse; puis on fait glisser le support et le verre qui sont à une température égale ou supérieure au point de transition vitreuse l'un vers l'autre à travers une couche mince d'agent filmogène vapeur qui s'évapore en continu à proximité d'une interface située entre le support et le verre.
