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°.

Dependent claims

A container comprising:

leak-tight walls for containing a liquid, one of the walls forming a bottom of the container;
wherein said bottom wall of the container comprises a plurality of partition walls rising towards the inside of the container, bounding zones between them successively enclosed one within the other, each of the zones being in communication with an adjacent enclosed zone through a passageway made in the partition wall comprising a threshold located on the wall of the container;
wherein the threshold in the passageway between a zone and an adjacent enclosed zone constitutes a low point in the zone and a high point in the adjacent enclosed zone;
and
wherein for a given zone, the passageway between the given zone and the zone in which the given zone is enclosed and the passageway between the given zone and the zone enclosed in the given zone are arranged within angular sectors bounded by imaginary geometrical angles which are opposite to each other at a summit, the summit being located at the lowest level zone in the container, the angles being less than 45°.
