Abstract: A container including sealed walls for containing a liquid, one of the walls forming a container bottom, the container bottom including a plurality of partitions defining therebetween areas contained consecutively inside one another, each of the areas communicating with an adjacent contained area via a passage including a threshold. The threshold of the passage between one area and an adjacent contained area is a low point of the area and a high point of the adjacent contained area, for any given area. The passage between the given area and the area in which the given area is contained, and the passage between the given area and the area contained within the given area are arranged in angular sectors defined by imaginary geometric angles opposed at the vertex thereof, the vertex being located in line with a lower-level area of the container, the angles having a size of less than 45°.

Abstract: The invention relates to a tank (1) for storing a liquid, comprising a wall (10) made of plastic and a device for stopping the filling of said tank (1) with a liquid at a maximum fill level, this device extending inside the tank (1) and comprising at least one opening (71) of which the position inside the tank (1) fixes the said maximum fill level. The device that stops the filling of this tank (1) comprises a first part formed with the wall (10) and a second part which is fixed hermetically to the first part.

Abstract: A container including an inner wall including an opening sealed by a plate of a technical module including at least one technical device, the sealing of the opening resulting from insertion of the plate into the opening in a main direction. The plate of the technical module includes a flange including a bearing surface, and the inner wall of the vessel includes a bearing directed towards the inside of the container, which acts as a seat for the flange, to block passage of the plate of the technical module through the opening towards outside of the container.

Abstract: A conducting system for a fuel tank filling pipe, including a filling bowl made of a conducting plastic, a filling nozzle guide, also made of a conducting plastic, provided with deformable teeth, and in direct contact with the filling bowl, and a metal head. The bowl and the guide are inserted into the metal head such that the teeth are in permanent radial contact with the metal head when the bowl and the guide are mounted in the filling pipe.

Abstract: A closure system for the head of a fuel tank filling pipe, including: an essentially circular closure piece provided with a relief; and a moving part for (un)locking the closure piece by a rotational movement about the axis of the closure piece, the moving part including a relief configured to engage with the relief of the closure piece by a bayonet system. The reliefs are of a symmetrical shape allowing continuous rotation in both the clockwise and anticlockwise directions of the moving part relative to the closure piece.
