  • Patent number: 6422456
    Abstract: An insulating cup or container (50) and a method of manufacturing it comprises (first embodiment) a sidewall blank (12B) having two sections separated by a fold score (15), and a separate insulating sheet (18)(corrugated, ribbed, embossed, foamed, perforated, etc.) which is adhesively fastened to one of the sections. The blank is folded in half along the fold score, to form a three-layered assembly with the insulating sheet in the middle. To reduce the thickness of the seam, the blank is thinned in the area adjacent a fold score prior to folding. The assembly is wrapped around a mandrel to bring the outer edges together at a side seam (22S) to form a sidewall 12. The side seam is sealed, the bottom is added, and the rim is formed. In a second embodiment, the insulating layer can be a coating on one or both of the sections of the two-section starting blank. In a third embodiment, the insulating section (40) can be integral with, and extend from, one edge of the starting blank.

  • Publication number: 20020050513
    Abstract: A bulk box of corrugated cardboard has a readily repulpable water vapor barrier material incorporated in the outer liner, increasing the resistance of the box to penetration by moisture in humid conditions, and especially reducing hysteresis effects in conditions of cyclic humidity. The box has increased strength and bulge resistance, and achieves performance equally as good as or better than a conventional box without the water vapor barrier, while at the same time enabling less pulp fiber to be used in the construction of the box.

  • Publication number: 20020036229
    Abstract: The invention is a shipping container blank whereby all surfaces and edges are sealed by an overlying a plastic film material. A container subsequently made from the blank is rendered highly water resistant. The film material is applied to both sides of the blank and severed from the supply source. The covered blank is then heated above the softening point of the film. The film becomes bonded to the surfaces of the blank and sags around the edges and into any openings so that the film on the two sides of the blank come into contact and are sealed to each other. The edges and any slits and cutouts are then trimmed, as by a die cutter, while preserving the seals along the edges. Containers made by the process can generally be recycled, in contrast to wax or resin impregnated corrugated board.

  • Patent number: 6138903
    Abstract: A multi-ply paperboard container for use as a bulk material bin has elongate rectangular cross-sectioned tubular inner and outer shells having walls that are spaced apart from one another. Rectangular panels, having a width less than the width of the walls of the shells, are located between and adhesively bonded to each overlying pair of walls. Thus, gaps are formed between the inner and outer shell at each corner of the container. The corners of the inner and outer shells are crushed to provide wide soft corners. These gaps and crushed corners permit the container to be easily knocked down to a flat configuration without a substantial amount of spring-back. The container includes a bottom cap having end flaps inserted between the inner and outer shells or between adjacent plies in the inner or outer shells, and the outer shell has closure flaps which fold over the bottom cap to keep the end flaps in place. When loaded, the bottom cap and closure flaps prevent the container walls from bending outwardly.

  • Patent number: 5772111
    Abstract: This invention pertains to an upstanding container having a corrugated sidewall. Flutes in the medium of the corrugated sidewall follow preferably equal and opposite alternating lateral divergences from generally longitudinal upstanding axes. Preferred alternating divergences are waves having gradually changing angles of divergence from the respective upstanding axes. Thus, preferred medium is characterized by a pattern of wavy flutes. The pattern of wavy flutes provides improved strength and rigidity imparted by the horizontal components of the waves. Wavelength of the flutes is generally no greater than the height of the container. Wave amplitude is preferably between about 1/20th and about 1/80th of the circumference of the container. Spacing between flutes may be uniform from top to bottom of the container. In some embodiments, spacing between flutes is greater at or adjacent the top of the container than at or adjacent the bottom of the container.

  • Patent number: 5702053
    Abstract: A composite insulator-packing container is made of a single-faced corrugated fiberboard composed of a linerboard and a corrugating medium joined to one surface of the linerboard. The fiberboard is fabricated in a form of a polygonal prism by folding an original single-faced corrugated fiberboard along ruled lines such that the linerboard is located at an outer periphery of said packing container. The ruled lines are orthogonal to flutes of the corrugating medium and are formed such that when the fiberboard is folded along the ruled lines in the form of the polygonal prism, outer peripheries of shade portions formed around a core member of a composite insulator internally touch or are located radially inwardly near inner peripheral sides of the polygonal prism. A method for packing the composite insulator is also disclosed.
