Multi-chamber container having two interior partitions

A container for storing and pouring a liquid, such as motor oil, the container having top, bottom, and lateral walls when disposed in an upright position for storing the liquid and a spout adjoining and extending upwardly from the top wall in the upright position of the container, the container being closed except for the spout;

• the container having two interior partitions extending in generally horizontal directions in an upright position of the container, namely a first partition extending across the container except for an orifice defined by the first partition and an second partition extending across the container except for an orifice defined by the second partition, the partitions dividing the container into three interior chambers, namely a primary chamber between the first partition and the bottom wall, a secondary chamber between the first and second partitions, and a tertiary chamber between the top wall and the second partition, the primary chamber having a volume which is substantially larger than the combined volumes of the secondary and tertiary chambers;
• the partitions constituting means for preventing the primary chamber from being emptied of a liquid when the container is rotated from the upright position in a rotational direction tending to raise the second orifice relative to the first orifice and to lower the first orifice relative to the second orifice upon initial rotation of the container, unless the container is inverted sufficiently upon further rotation of the container in the same direction to dispose the first orifice at the lowest part of the primary chamber and to dispose at least part of the second orifice below at least part of the first orifice;
• the container having four lateral walls, namely two relatively narrow walls and two relatively wide walls, each orifice extending between a respective one of the partitions and a respective one of the relatively narrow walls, wherein the orifice defined by the first partition extends between the first partition and a first one of the relatively narrow walls, wherein the orifice defined by the second partition extends between the second partition and a second one of the relatively narrow walls, and wherein the spout is disposed so as to be substantially tangent, at an inner surface of the spout, to a plane defined by an inner surface of the second one of the relatively narrow walls.
