Abstract
A hinged lid packet has an integral inner frame comprising a recessed panel extending upwardly from the front wall of the body of the packet, and a pair of side flaps extending backwards from the sides of the recessed panel. A cut-away part is formed at the top of each side flap to provide access for securing each outer flap of the lid of the packet to the respective inner flap. Each inner flap may be of a shape corresponding to the cut-away part, so that with the lid closed the inner flap and the respective side flap are substantially contiguous.
