Two piece telescopic cigarette packet - has hinged lid opened by pushing and pressing on front face of inner box with hinge sited over strap

摘要

The package comprises two telescopic boxes (1,2), the inner one of which (2) may have an obliquely jointed hinged lid (3), the top horizontal panels of the two boxes being overlain and glued together. The hinge (6) is sited centrally over a resilient panel (8) so the lid pivots open if the front panel is pressed then pushed. The resilient panel maintains the hinge at a constant distance from a certain line (7), and may be subjected to tension and flexure when the box is opened. The outer box may use two cardboard cut-outs from one blank, the cut-outs being connected by overlapping the side flaps.
