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&#xb0;.

Container comprising a liquid trap

The invention relates to a tank () for storing a liquid, comprising a wall () made of plastic and a device for stopping the filling of said tank () with a liquid at a maximum fill level, this device extending inside the tank () and comprising at least one opening () of which the position inside the tank () fixes the said maximum fill level.
