A motor vehicle tank, having a first tank shell and a second tank shell, the first tank shell and the second tank shell defining between each other at least one section of a tank volume of the motor vehicle tank, the first tank shell and the second tank shell respectively having an edge area having a joining flange, the first tank shell and the second tank shell being integrally joined to each other at their joining flanges across a common joining surface, the first tank shell and the second tank shell respectively being a multicomponent tank shell, which includes a barrier film and at least on its edge area an inner wall section that is injection molded onto the inner side of the barrier film pointing toward the tank volume as well as an outer wall section injection molded onto the outer side of the barrier film pointing away from the tank volume, wherein the barrier film of each tank shell is formed in such a way that with the approach to the common joining surface in the area of the joining flange it runs away from the tank volume and toward the outer tank side, so that an integral joint of the tank shells is formed from a first joining area situated closer to the tank volume, in which the injection molded inner tank wall sections of the two tank shells are joined to each other, and a second joining area situated further removed from the tank volume, in which the barrier films of the two tank shells are joined to each other.

A motorized vehicle tank, having a first tank shell and a second tank shell, where the first tank shell and the second tank shell between them define at least one section of a tank volume of the motorized vehicle tank, where the first tank shell and the second tank shell are connected with each other, where at least one tank shell out of the first and the second tank shell is a multicomponent tank shell which exhibits a barrier foil and at least area-wise an inner wall section injected by injection-molding onto the internal side of the barrier foil facing towards the tank volume and/or an outer wall section injected by injection-molding onto the external side of the barrier foil facing away from the tank volume; the motorized vehicle tank exhibits in at least one tank wall section formed from the multicomponent tank shell an eversion formed integrally at the barrier foil, which projects relative to the tank wall region surrounding it.

A vehicle tank, in particular for holding a fuel, in particular gasoline and/or diesel fuel, having: a first and a second partial shell, wherein the first and second partial shell are connected to one another in a partial shell joining area, and a barrier layer substantially, preferably completely, covering an outer surface of the first partial shell and an outer surface of the second partial shell, respectively, wherein the barrier layer spans the partial shell joining area on an outer surface of the vehicle tank.

A resin-made fuel tank includes: a resin-made fuel tank body provided by bonding an upper half body and a lower half body to each other; and a barrier sheet layer provided on an inner surface of the fuel tank body and provided for reducing permeation of fuel from the fuel tank body, wherein an edge of the barrier sheet layer is disposed in a vicinity of an upper bonding surface and a lower bonding surface where the upper half body and the lower half body are bonded to each other in a mating manner, the edge has a bent portion which bends toward an outside of the fuel tank body, and the bent portion is embedded in the fuel tank body at a position spaced apart from the upper bonding surface and the lower bonding surface.

A mount for a double-walled vessel includes a first support to support the mount against an outer wall of the double-walled vessel, a second support to support the mount against an inner wall of the double-walled vessel, and a flexible member connecting the first support and the second support. The first support and can be arranged at a first end of the flexible member and the second support can be arranged at a second end of the flexible member opposite to the first end. Further described are a vessel including at least one such mount as well as a vehicle including such vessel.

A fuel tank protection system having an outer wall for a fuel tank, an inner wall for the fuel tank, a gap between the inner wall and outer wall, and an intumescent material located within the gap between the inner wall and the outer wall.
