<p>1. A container of a flexible or semi-rigid material for receiving a liquid, characterized in that it has two planar bearing sides (2) forming a dihedron whose angle (alpha) is smaller than 90 degrees when the container is filled with liquid, these two planar sides (2) being interconnected by a neck (5) at the end of which is formed a liquid-expelling opening, the two planar bearing sides (2) are part of two semi-shells (1) fixed to each other on their periphery in a median plane relative to which these two semi-shells (1) are symmetrical, the fixing being preferably achieved by welding, and this container is provided with a liquid expelling passageway (12) whose outlet opening is located at a level higher than the level (N) of the liquid when the container bears on one of its bearing sides (2), and the distribution of the weight of the full or empty container is so chosen that the vertical passing through its centre of gravity is located inside the perimeter of one of the bearing sides (2) bearing on a horizontal plane.</p> |
