Abstract

La présente invention concerne un tube soudé sans bourrelet et son procédé de fabrication. Le tube comprend un corps de tube (1). Le corps de tube (1) comprend un film interne (11) et un film externe (12) empilés ensemble. Le film interne (11) et le film externe (12) sont alternativement combinés ensemble et forment respectivement des orifices étagés à angle droit aux deux extrémités dans la direction circonférentielle du corps (1). La surface externe (111) du film interne (11) au niveau de l'un des orifices est exposée à l'extérieur du film externe (12), alors que la surface interne (121) du film externe (12) au niveau de l'autre orifice est exposée à l'extérieur du film interne (11). La surface interne (121) du film externe (12) qui est exposée est soudée par recouvrement sur la surface externe (111) du film interne (11) qui est exposée. De plus, les deux extrémités dans la direction circonférentielle du film externe (12) sont soudées ensemble, en même temps que les deux extrémités dans la direction circonférentielle du film interne (11) sont soudées ensemble. Le procédé de fabrication comprend : les étapes de fabrication d'un film mince, combinaison du film mince, enroulement pour la formation d'un tube, et soudage. Le film interne (11) et le film externe (12) sont alternativement combinés ensemble durant la combinaison du film mince. Le procédé de fabrication du tube sans bourrelet multicouche permet de réduire les difficultés d'un procédé d'impression. Le tube est lisse et sans bourrelet au niveau de la soudure. Le tube bénéficie d'un aspect global esthétique. De plus, la nécessité de rogner pour obtenir les orifices étagés à angle droit est rendue inutile, le flux du processus de fabrication est simple, et les coûts de fabrication du tube sont réduits.
