  • Patent number: 6312370
    Abstract: A machine for container formation by folding a die-scored paperboard structure to close flaps shaped by the scoring that serve as the top and bottom of the container. A scored paperboard sheet is loaded onto a male pedestal inner pattern such that the foldable top and bottom container portions extend beyond the pattern, whereupon armature driven semicircular outer patterns, having upper and lower fingers adapted to be driven by corresponding fluid driven pin stabilizers, close upon the sheet. While closed over the sheet, the pins are activated to move the fingers inward on the inner pattern and force fold the container along the score lines, followed by automatic retraction of the pins and outer patterns. The container is thus pre-folded in preparation for shipping as a flat paper form that is ready for folding on the crease lines thus formed. One or both flaps of the container can be folded along the crease lines to form a closure at one or both ends.

  • Patent number: 5472139
    Abstract: An improved container for storing and transporting a hot pizza product that includes a top and bottom with nonzero Gauss curvatured structures over a major portion of the supporting surface so that less material need be used for fabrication without a lowering of structural integrity. The top and bottom members are adapted to nest with other like tops and bottom members to reduce the need storage space near the pizza oven where they are ready for use without preassembly. The floor of the bottom comprises upstanding projections with small top surface area to reduce the heat conduction path and to support the product above the floor to form an air insulating space between the product and the floor. The bottom member includes a sidewall that intersects the floor to form a supporting line when resting on a supporting surface, thermal conduction being limited to such line. The curved, convex shape of the floor then provides a closed air insulating space between the bottom and the resting surface.

  • Patent number: 5452844
    Abstract: Bag of the type obtained from a single elongate planar cutting presenting two parallel long edges with the cutting being backfolded in order to define the two faces of the bag. The faces meet at a transverse bottom formed by the medial portion of the cutting and the two faces of the bag are joined edge to edge by their two long edges and the small side opposite to the bottom. The bag is characterized in that the bottom is comprised of two triangular facets which are opposite back to back from the central region of the bottom and the two triangular facets are bent back towards the internal volume of the bag. The apex of the triangle is oriented toward the outside and meets the corresponding long edge of the bag. Each long edge of the bag is formed by edge joining of the two faces and comprises, in the zone between the triangle apex and the bag base, four thicknesses or layers from the initial cutting, sealed to each other.

  • Patent number: 5437406
    Abstract: A paperboard container of generally semi-rigid construction and formed from a unitary blank of paperboard folded in the general shape of a U. The interior surface of the container is coated with a thermoplastic polymer barrier layer, the container having a manually openable, normally closed pour spout at one upper edge portion, and also having a recessed or raised bottom. The container is particularly adapted for packaging granular, dry material such as corn flakes, pretzels, and the like. Due to its construction and the thermoplastic barrier layer, the usual inner pouch which contains dry cereal is omitted, thereby effecting savings in both material and in assembly of the final package. In one embodiment, an opening is provided for carrying the package, the opening located at the top of the container. In another embodiment one side wall of the panel is provided with an extension to serve as a reclosure flap.

  • Patent number: 5423477
    Abstract: A pizza box having a top and bottom each formed of a single layer of biodegradable, insulating material, such as molded fiber. The bottom provides an insulating airspace between the hot pizza product and the bottom major surface area and another insulating airspace between the bottom undersurface and a resting surface. The top and bottom, when closed, provided a closed chamber with no external air circulation. Thermal conduction paths are reduced by the small surface area contact between the bottom and the product and the small surface contact area between the bottom and a resting surface. Additional features include a closed storage chamber without air vents, a truncated cone or truncated pyramid shape, moisture absorption by the top inner surface, liquid resistance by the bottom top surface, stackable tops and bottoms, air restricting closure walls, cutting channels which also add strength to the bottom and radiation reflective color.
