  • Patent number: 3979046
    Abstract: Tops of shipping cases are routinely severed for price marking of package contents, and this process incurs substantial cutting of contents, e.g. cereal packages and the like. Although package contents adjacent side panels are most likely to be cut by the store clerk, a substantial number of packages adjacent the end flaps are also likely to be cut, specifically those packages positioned at the end-flap gap. A shipping case is disclosed which substantially eliminates this kind of damage to the contents, and increases the strength of the case. In accordance with the present invention the shipping case includes a top panel having dependent major end flaps extending downwardly over minor end flaps, the dependent flaps being free of any connection to the minor end flaps along the entire edge adjacent the top panel, and being attached to said dependent flaps beyond this zone of unattachment. The case minor end flaps have attached at their top middle edges separation strips of the corrugated material.

  • Patent number: 3941303
    Abstract: Tops of corrugated shipping cases are routinely severed for price marking of package contents, and this process incurs substantial cutting of contents, e.g., cereal packages and the like. A corrugated shipping case is disclosed which substantially eliminates this kind of damage to the contents. In accordance with the present invention, the shipping case includes a top panel positioned adjacent the tops of the packaged contents, which top panel includes dependent flaps extending downwardly along at least three sides of the package, the dependent flaps being free of any connection to the body along the entire edge adjacent the top panel, and being attached to the body of the case beyond the cutting zone. In addition, one of the flaps is formed by an S fold of the corrugated material at the top of a side panel, immediately adjacent the top panel.
