A container (101) has a constant wall thickness vessel (102) with a valve (103) crimped on at a neck (104) in the vessel. The valve has a dispensing stem (105). The vessel is circularly cylindrical and formed with an groove (106) extending parallel with the length of the vessel, from a base (107) to the neck (104). When the container is lain on its sidewall (108), it will roll, changing its orientation, until the groove (106) is at the surface as shown in FIG. 7, with the groove in effect floating on the surface of the liquid, providing an indication of the actual quantity of content in the container. |

1. A pressurised liquid dispensing container of the type defined, the container comprising a vessel for containing the liquid under pressure, the vessel defining an inflectionless cylindrical envelope; the container having within the inflectionless cylindrical envelope:
a formation and/or a discrete element in the vessel which causes the centre of gravity of liquid contents of the container to be positioned differently when the container is in a lain-on-side attitude, the formation-or-element also being such that: when the side wall of the container is lain on a surface and the container is at least substantially full of liquid contents, the centre of gravity of the liquid biases the container to roll towards one orientation thereof and when the container is at least empty or nearly so, the centre of gravity of the container, in the absence or near absence of liquid contents, biases the container to roll towards another orientation thereof. |
