Abstract
Abstract A pack for cigarettes and like smoking articles has a frame ( 101 ) outside the charge of cigarettes but inside a flexible wrap, which is preferably a sealed enclosure of a barrier material such as a metal/plastic laminate, or metallized foil. The inner frame which is not rigid since its side ( 104 ) and end ( 108 ) flaps are free except where attached to a major panel ( 102 ) acts to collate and protect the charge of cigarettes and to allow heat-sealing or other sealing pressure to be exerted more efficiently than would otherwise be possible.
