The invention relates to a fuel tank for a motor vehicle, comprising a first and a second tank shell, between which at least one section of a tank volume of the fuel tank is defined and which has an edge region with a joining flange, the first and the second tank shell being joined to each other via a common joining surface in a cohesive manner at the joining flange thereof, the first and second tank shells are multi-component tank shells and have a barrier film and, at least in the edge regions thereof, inner wall sections/outer wall sections which are injected onto the inner side/outer side of the barrier film facing/facing away from the tank volume by means of an injection molding technique, the barrier film of each tank shell is shaped such that it extends away from the tank volume and towards the outside of the tank in the region of the joining flange when approaching the common joining surface, such that a cohesive joining connection of the tank shells is formed by a first joining region near the tank volume and a second joining region away from the tank volume, the injected tank inner wall sections of the two tank shells are joined to each other in a first joining region, and the barrier films of the two tank shells are joined to each other in a second joining region.
本发明涉及一种机动车油箱,包括第一和第二箱壳,在其之间限定机动车油箱的箱容积的至少一个部段并具有带有接合法兰的边缘区域,第一和第二箱壳在其接合法兰处经由共同的接合面材料配合地彼此接合,第一和第二箱壳是多组分箱壳并具有阻隔膜和至少在其边缘区域具有以注塑技术喷射到阻隔膜的朝向/背离箱容积的内侧/外侧上的内壁部段/外壁部段,每个箱壳的阻隔膜成形为使其在靠近共同的接合面时在接合法兰的区域中背离箱容积并且朝向箱外侧伸展,以至于箱壳的材料配合的接合连接由靠近箱容积的第一接合区域和远离油箱容积的第二接合区域形成,在第一接合区域中两个箱壳的被喷射的箱内壁部段彼此接合,在第二接合区域中两个箱壳的阻隔膜彼此接合。
