Abstract

A hinged lid packet has an inner frame provided at each side with a downwardly facing edge, which engages with a upwardly facing edge in the side wall of the packet to limit downward movement of the inner frame. The edge in the inner frame may be formed by an outwardly bent corner; and the corresponding edge in the side wall may be formed by a rectangular cut-out, such as a slot.
