Automatically opening box

An automatically opening box comprising:

• (a) a rectangular base formed from two rectangular panels joined by a foldable spine;
• (b) a pair of perpendicular opposed sides extending upwardly from edges of the base at base corners perpendicular to the spine and each of the perpendicular opposed sides having a vertical fold aligned with the spine, a pair of parallel opposed sides extending upwardly from edges of the base at base corners parallel to the spine, and adjacent sides connected at side corners to define an open topped box;
• (c) at least two side corners include sprung hinges;
• (d) both sides of one of the pairs of opposed sides having diagonal folds;
• (e) the automatically opening box having two configurations, a collapsed configuration in which both pairs of opposed sides are folded down to be parallel to the base, the base is folded along the spine and vertical folds, and a fastener secures the automatically opening box in the collapsed configuration, and a deployed configuration in which the fastener is released and the sprung hinges act to deploy the sides and base.
