ABSTRACT:
A container for receiving a food product is formed from a shaped blank of paper, paperboard, cardboard or a similar material. A hinge arrangement comprising at least two and preferably three parts is provided between one of the side walls and one of the end walls to allow the partially formed container to be moved easily between a flat configuration suitable for transportation or storage and an erect configuration for receiving a food product. In the erect configuration one part of the hinge arrangement is sandwiched between another part of hinge arrangement and the end wail. In the flat configuration these two parts of the hinge arrangement lie in substantially the same plane. An integral lid may be provided.
