Patent number: 6312370Abstract: 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.Type: GrantFiled: June 7, 1999Date of Patent: November 6, 2001Inventor: Gary Allmon

Patent number: 5472139Abstract: 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.Type: GrantFiled: September 22, 1993Date of Patent: December 5, 1995Assignee: Invention Machine CorporationInventors: Michael Valdman, Semyon Litvin, Igor Gridnev, Vladimir M.

In another embodiment one side wall of the panel is provided with an extension to serve as a reclosure flap.Type: GrantFiled: July 2, 1993Date of Patent: August 1, 1995Assignee: International PaperInventors: Robert L.

Patent number: 5431277Abstract: A bundle pack, made from thin cardboard, for a plurality of cuboid small packs, especially cigarette packs (10). In order to accommodate cigarette packs (10) of small dimension, namely height, in a bundle pack having standard, that is to say larger outer dimensions than the packs, a bottom wall (23) is set back inwards according to the height of the cigarette packs. A free compensating chamber (26) is obtained underneath the bottom wall (23). The downwardly open compensating chamber (26) is surrounded all-round by a double-walled edge.Type: GrantFiled: April 25, 1994Date of Patent: July 11, 1995Assignee: Focke & Co. (GmbH & Co.)Inventor: Heinz Focke

Patent number: 5423477Abstract: 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.Type: GrantFiled: June 24, 1993Date of Patent: June 13, 1995Assignee: Invention Machine CorporationInventors: Michael Valdman, Michael Schum

Patent number: 5411203Abstract: 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.Type: GrantFiled: July 29, 1994Date of Patent: May 2, 1995Assignee: Packart HoldingInventors: Thierry Bochet, Jean-Pierre Moriniere

Patent number: 5377903Abstract: A paperboard tray which resists warping is formed of a unitary blank, the blank having a polymer coating on its tray interior forming surface. The polymer coating is typically a heat resistant, non-stick, FDA approved polymer applied by extrusion coating. The upstanding sidewalls of the tray are joined to respective peripheral portions of the tray base through curved score lines on the tray interior surface. Curved cut lines on the exterior tray surface are each aligned with respective curved score lines on the tray interior surface, the cut lines extending 75 to 90 percent through the blank. The curved score lines and their complementary cut lines may be curved either convex outwardly or concavely inwardly with respect to the tray base.Type: GrantFiled: June 16, 1994Date of Patent: January 3, 1995Assignee: International Paper CompanyInventors: Robert L. Gordon, George H. Naugle, David E. Stier

Patent number: 5358175Abstract: A container formed of foldable sheet material including a body of a slightly tapered inverted conical configuration having opposed pairs of closure flaps integrally hinged to the upper rim of the body and foldable to overlie the upwardly directed open mouth of the container. The inward folding of the flaps inwardly flex corresponding portions of the body wall to a generally rectangular configuration adjacent and downward from the rim. The outer flaps interlock by a cooperating tongue and slot. In variations, integral or bonded handles are provided to overlie the closed container. Additional sealing at the defined corners between adjacent flaps is achieved by integrally formed folding gussets.Type: GrantFiled: March 17, 1993Date of Patent: October 25, 1994Assignee: Dopaco, Inc.Inventor: Liming Cai

Patent number: 5353984Abstract: A paper board having a desired pattern and a plurality of folding lines embossed thereon defining a polygonal bottom section, an inner peripheral wall section extending outwardly from each side of the bottom section and pairs of corner sections disposed between two adjacent inner peripheral wall sections permitting the formation of a container. Wall edge, outer wall and plate sections extending outwardly from each inner peripheral wall section may be folded outwardly and downwardly to the underside of the bottom section to form hollow walls of the container.Type: GrantFiled: October 13, 1993Date of Patent: October 11, 1994Inventors: Yuan-Hsin Liu, Richard C.
