  • Packaging of smoking articles
    Patent number: 6237760
    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.
