Abstract
A five-piece open container comprises a bottom piece formed of plastics material and four side pieces also formed of plastics material and pivotally mounted to the bottom piece so that the side pieces may be pivotally moved between an erected position and a non-erected position. In the upper corner of each piece are provided parts which are integral with the side pieces and which enable the side pieces to be maintained in an erected inter-engagement. One of the integral parts ensures a securing arrangement when the side pieces are in the erected position, but it may be manually flexed outwardly from inside the container to enable the disengagement of the side pieces from one another so that they may be moved into a non-erected position.
