Fluid Container

A fluid container comprising a body having a neck, and a mouth, said container being deformable at said neck from a first stable condition to a second stable condition thereby to change the relative angle of said mouth, wherein:

• a) in the first condition said neck defines a channel at one side which is substantially ‘V’ shaped and transverse to the upright axis of said container;
• b) said ‘V’ shaped channel includes an upper edge, and a relatively longer lower edge;
• c) said ‘V’ shaped channel comprises a long sidewall edge and a short sidewall edge in a ratio of from about 1.25:1 to about 1.75:1 at the point of the greatest channel depth;
• and
• d) said channel is adapted to be closed by approaching sidewalls in the second condition and to define a pre-determined direction of movement from said first condition to said second condition.
