  • Patent number: 7806313
    Abstract: The present invention includes a blank and container formed from cellulose-based materials configured to form an octagonal shaped display and/or shipping container. The container includes a multiple sidewall thickness throughout a majority of the various sidewalls to add to stacking strength and stability of the container.

  • Patent number: 7794567
    Abstract: Disclosed is an uncoated facestock product having enhanced printability, holdout, and edge wick properties, which are attained through a combination of manufacturing techniques including increased refining of the furnish, sizing, increased hard nip calendering, and the use of extended nip calendering. The resulting uncoated facestock product has the following properties: a density between about 0.7 and 1.0 g/cc and/or an ash content of less than about 15% as measured by the 525° C. standard test method; and a finished surface having a Sheffield smoothness between about 50 and 150 Sheffield units and a Parker Print Surf roughness (PPS-10) less than about 5.0 microns.

  • Patent number: 7654440
    Abstract: An octagonal bulk bin has sidewalls, end walls and diagonal corner panels interposed between adjacent sidewalls and end walls. Major bottom flaps are foldably joined to a bottom edge of the sidewalls, minor bottom flaps are foldably joined to a bottom edge of the end walls, and diagonal bottom flaps are foldably joined to a bottom edge of the diagonal corner panels. A cut separates each major bottom flap from an adjacent diagonal bottom flap, and a web panel connects adjacent side edges of the minor bottom flaps and diagonal bottom flaps. According to one aspect of the invention, each diagonal bottom flap, web panel, and portion of an adjacent major bottom flap are crushed. According to another aspect of the invention, differently shaped notches in a free edge of the minor flaps form locking tabs that are engaged in slots near a free edge of the major flaps.

  • Patent number: 7652794
    Abstract: A prepress workflow process suitable for generating a reproduction composite image from a source image that may be tolerant to or exhibit improved tolerance to misregistration when printed is provided. Embodiments of the prepress workflow process include obtaining a source image. Next, N?2 color separations are generated from the source image. The color separations may be process or non-process color separations. The N color separations are first processed globally for improving the misregistration tolerance of a reproduction composite image to be formed therefrom. If the misregistration tolerance of the reproduction composite image is not acceptable to be user, at least a portion of each N color separation may be further processed at a local level for producing an improved misregistration tolerant reproduction composite image.

  • Patent number: 7648772
    Abstract: A sheet of cellulose based material having enhanced strength, particularly the dry strength, substantially unaffected repulpability is disclosed. The sheet of cellulose based materials generally includes a first cellulose based material connected with a second cellulose base material element. The first cellulose based material is formed by separating a portion of the fiber from a furnish, treating the separated portion with a cationic wet strength resin which is allowed to bond to the fiber. The treated fiber is them mixed with the untreated balance of the fiber at some point before the paper machine. The fiber that is separated may be secondary fiber, virgin fiber or combinations thereof. The second cellulose base material element is substantially free from any treatment. The second cellulose base material element may be include substantially all untreated fibers.

  • Patent number: 7607566
    Abstract: A container and its associated container blank for shipping and displaying products. The container blank includes a plurality of side panels, bottom panels, and top panels that are erectable into a fully enclosed shipping container. Formed in some of the side panels and some of the top panels are removable punch-out window panels. When removed, the punch-out window panels leave a top panel that defines a periphery around the “window” area. Various stacking tabs and slots are configured in the bottom panels. The stacking tabs and stacking slots are positioned such that when engaged and the containers are in a vertically stacked arrangement, the stacking tabs bias against a portion of the periphery of the top panel. When not engaged, the container has a flat bottom.

  • Patent number: 7607567
    Abstract: A container (10) for shipping products has opposed end walls (11, 12) and opposed side walls (13, 14), each having an inner wall panel (16, 17 and 20, 21, respectively) and an outer wall panel (18, 19 and 22, 23, respectively) defining double thickness walls. The outer wall panels in the side walls are disposed orthogonally to the outer wall panels in the end walls to define a rectangular or square outer container configuration, and extension panels (25a, 25b) on opposite side edges of a first pair (16, 17) of the inner wall panels extend diagonally across interior corners of the container to define with the inner wall panels an octagonal inner container configuration. Bottom flaps (40, 41, 42 and 43) foldably connected to the bottom edges of the outer wall panels form a peripheral bottom wall (15), and include quick-lock detents (46, 47 and 52, 53, 54) to enable quick and easy set up of the bottom.

  • Patent number: 7607564
    Abstract: A corrugated bulk container for shipping, storing and dispensing liquids and semi-liquid fluids. The container is a laminated triple wall open-ended tube having side walls and end walls, and a bag assembly is supported in the tube for containing the liquid or semi-liquid fluid. The bag assembly includes a bag having a fill valve and a dispensing valve attached to it, a bag cassette to which a bottom end of the bag is attached, and a fill valve support plate to which a top end of the bag is attached. The bag cassette has structure to receive and hold the dispensing valve in position relative to a dispensing valve opening in the tube, and the fill valve support plate has structure to receive and support the fill valve. The container is attached to a pallet by severable structure, and the fill valve support plate is attached to the tube by severable structure so that the bag assembly can be removed from the container, for easy collapse of the container for disposal or recycling.

  • Patent number: 7487904
    Abstract: The present invention includes a blank and container formed of cellulose-based materials configured to form a reusable and collapsible container. The container in the partially assembled, knock-down position lies substantially flat and is capable of being stacked and shipped. Arrival at a job site or at a time requiring the use of the container, the partially assembled knock-down container may be easily converted into a fully erect container ready for use as intended. Once loaded with product, the first and second top panels may be folded down to enclose the container. The container positions the relief scores primarily in the side panels with only a single relief score in the bottom panel. This configuration allows the bottom panel to distend while the container is in the collapsed state while not adversely affecting overall container strength.

  • Patent number: 7487902
    Abstract: The present invention includes a blank and container formed of cellulose-based materials configured to form a triangular shaped container. The container includes a triangular shaped bottom panel, side walls and a rear wall that define a first triangular volume. The top panel and second side panels generally form a second triangular volume that is slightly larger than the first triangular volume. The second triangular volume is configured to fold over the first triangular volume such that the top panel and second side panels fully enclose the bottom panel and the first side panels. The container is locked by a friction fit between juxtaposed tabs inserted into a slot located between the ends of the intersecting first side panels.
