A container arranged to receive an item and comprising: first and second faces (110, 120) joined at a first side and at a second side opposite the first side, each face (110, 120) comprising: a first line of weakness (114a, 124a) extending between, and tending inwardly between, end regions of the first side, the first line of weakness dividing a first edge region (116a, 126a) of the face from a central region (117, 127) of the face (110, 120); and a second line of weakness (114b, 124b) extending between, and tending inwardly between, end regions of the second side, the second line of weakness dividing a second edge region (116b, 126b) of the face from the central region (117, 127) of the face (110, 120); a pair of internal flaps positioned between the first and second faces (110, 120) and spaced inwardly from the first and second sides (102, 104), and rotatably mounted on the second face at a first straight fold line such that each internal flap is rotatable with respect to the rest of the container about the first fold line; and a pair of actuating elements, each actuating element being connected to a respective internal flap of the pair of internal flaps by a second straight fold line which is parallel to the first straight fold line, wherein the container is moveable between: a first configuration in which the first and second faces (110, 120) are flat and the internal flaps are flat and parallel to the faces such that the container is at least substantially flat, and a second configuration in which the first and second edge regions (116, 126) are at an angle with respect to the central region (117, 127) of the faces (110, 120) and the internal flaps are at an angle with respect to the central region (117, 127) of the faces (110, 120) and arranged to act as spacers between the first and second faces, wherein the container is arranged to adopt the second configuration when a pressure is applied to the first and second sides (102, 104). first and second faces (110, 120) joined at a first side and at a second side opposite the first side, each face (110, 120) comprising: a first line of weakness (114a, 124a) extending between, and tending inwardly between, end regions of the first side, the first line of weakness dividing a first edge region (116a, 126a) of the face from a central region (117, 127) of the face (110, 120); and a second line of weakness (114b, 124b) extending between, and tending inwardly between, end regions of the second side, the second line of weakness dividing a second edge region (116b, 126b) of the face from the central region (117, 127) of the face (110, 120); a first line of weakness (114a, 124a) extending between, and tending inwardly between, end regions of the first side, the first line of weakness dividing a first edge region (116a, 126a) of the face from a central region (117, 127) of the face (110, 120); and a second line of weakness (114b, 124b) extending between, and tending inwardly between, end regions of the second side, the second line of weakness dividing a second edge region (116b, 126b) of the face from the central region (117, 127) of the face (110, 120); a pair of internal flaps positioned between the first and second faces (110, 120) and spaced inwardly from the first and second sides (102, 104), and rotatably mounted on the second face at a first straight fold line such that each internal flap is rotatable with respect to the rest of the container about the first fold line; and a pair of actuating elements, each actuating element being connected to a respective internal flap of the pair of internal flaps by a second straight fold line which is parallel to the first straight fold line, wherein the container is moveable between: a first configuration in which the first and second faces (110, 120) are flat and the internal flaps are flat and parallel to the faces such that the container is at least substantially flat, and a second configuration in which the first and second edge regions (116, 126) are at an angle with respect to the central region (117, 127) of the faces (110, 120) and the internal flaps are at an angle with respect to the central region (117, 127) of the faces (110, 120) and arranged to act as spacers between the first and second faces, a first configuration in which the first and second faces (110, 120) are flat and the internal flaps are flat and parallel to the faces such that the container is at least substantially flat, and a second configuration in which the first and second edge regions (116, 126) are at an angle with respect to the central region (117, 127) of the faces (110, 120) and the internal flaps are at an angle with respect to the central region (117, 127) of the faces (110, 120) and arranged to act as spacers between the first and second faces, wherein the container is arranged to adopt the second configuration when a pressure is applied to the first and second sides (102, 104).
