  • Patent number: 4966780
    Abstract: Packaging for coffee which is to be packed as quickly as is feasible after roasting, i.e., without undergoing substantial off gassing. The packaging preferably comprises a semi-rigid, substantially gas-impervious container capable of withstanding the pressures generated by the release of carbon dioxide and other gases from the fresh roasted coffee in the container. The semi-rigid container is preferably comprised of plastic and predetermined portions of the container are preferably capable of undergoing limited deformation. This prevents instability of the base of the container, thereby keeping its vertical axis erect, and ensures that the container does not become jammed within the shipping case in which it is transported due to lateral expansion.
