Adjacent Sidewalls Connected By A Folded Web Unitary With Both (i.e., "corner Fold") Patents (Class 229/186)
  • Patent number: 6736309
    Abstract: A quick erecting, disposable cooler which is transformable from a flat blank of corrugated sheet material may be non-destructively “knocked down” or collapsed after being semi-erected. The deployed cooler is moisture-proof and lacks leak paths, so it reliably stores and transports melting ice and beverage containers. A generally rectangular center panel is integrally bordered by pairs of end panels and side panels. Each side panel supports a foldable top panel with special knockouts and tabs to facilitate subsequent coupling of the panels. Each end panel has a small flap at its outer edge facilitating coupling. Four, integral, diametrically spaced-apart corner panels interconnect the center panel with the end and side panels. Score lines defined between the orthogonally arranged panels facilitate folding. Corner panels include diagonal score lines. The center panel forms a cooler bottom, and the end and side panels respectively form carton ends and sides when foldably deployed.

  • Patent number: 6729533
    Abstract: A reclosable container made of a material, such as paperboard, has a locking corner in the form of a two-section bellows panel that V-folds to form a slot between two rounded edges, free of any cut or raw edges. A closure panel folds over an upper edge of the container. Locking tabs at opposite ends of the closure panel fit into the slots. The rounded edges enable multiple openings and closings of the container without damage to either the slot or the locking tab.

  • Patent number: 6688516
    Abstract: An universal semi-automatic foldable box is generally disclosed comprising a box body (1) having a bottom panel (2), and two or more side walls (5), and the corresponding number of soft sheets (9) and spring strips (11). Each spring strip is connected to the bottom panel and at least one side wall. The side walls are connected to the bottom panel such that they can unfold and rise and the sheets form foldable connecting portions for connecting the side walls, and the spring strips serve to unfold the box flat. The spring strip has the property of remaining straight when unfolded but self-folding when it is slightly bent from its straight condition. The spring strips may be provided as an integral part of the box, or alternatively, may be a separate piece, which then can be attached by the user to the side walls of the box. The box body can be of different size and shape, such as for example square, sphere, rectangular, hexagonal, octagonal, and the like, and can be made of any material.

Locking tabs extend from the bellows panels of the container to limit lateral deflection of the sides and deformation of the container.

  • Patent number: 6019276
    Abstract: A blank for forming a carton for packaging a plurality of articles comprising a series of hingeably interconnected top, first side, bottom and second side panels (12, 14, 16, 18, 20) for forming an open-ended sleeve capable of receiving said articles, the top and bottom panels (12, 18, 20) being similarly non-rectangularly shaped substantially to correlate with the cross-sectional shape of the array of articles in a plan parallel to said top and bottom panels (12, 18, 20), wherein a gusset (38) comprising two hingeably connected gusset panels (58, 60) connects the first side panel (14) and top or bottom panel (12, 18, 20) which gusset (38) is adapted to facilitate movement of the first side panel (14) to correlate with the associated shape of a stowed array of articles during the formation of the carton (10).

  • Patent number: 5954263
    Abstract: Fluid-tight, boat-shaped packaging tray comprises a bottom surrounded by sides, connected in pairs by means of inwardly backfolded bellows. These bellows comprise two portions which contact one of the sides. The first portion of the bellows, adjacent to the side contacting the bellows, has an upper cut-out portion which provides for direct contact between the second portion of the bellows and the side of the packaging tray which contacts the bellows during fabrication. The fabrication provides a method whereby simple gluing of the internal faces of the sides intended to contact the bellows allows the front face of one of the portions to be assembled with the back face of the other portion in order to facilitate erection and assembly of container and to maintain the fluid-tight nature of the corner.

  • Patent number: 5881949
    Abstract: Packing container made of foldable packaging material, especially cardboard.The packing container consists of two parts, namely a container-like base part (10), open at the top, and a covering part (11) which can be placed on same. The base part (10) forms folds, namely folding units (30, 31) in the region of end walls (17, 18). Cover flaps (20, 21) of the upper covering part (11) enter the folding units in such a way that the folds of the end wall (17, 18) are fixed in the folded position by the insertion tabs (20, 21). Pulling out the insertion tabs (20, 21) frees the folds and thus the base part (10) can be shaped into a flat position.

  • Patent number: 5855317
    Abstract: A carton tray has an improved corner construction including long and short overlapped connector tabs wherein the long connector tab is secured by adhesive both to the adjacent short connector tab and to the end panel to which the short connector tab is foldably connected. The result is a strong corner post of at least three-ply thickness and one which can be easily assembled on a standard hot melt forming machine with application of adhesive to only one side of the blank from which the carton tray is constructed. The invention is further directed to the method of forming the improved carton tray with the corner post construction described above.

  • Patent number: 5842630
    Abstract: The present invention is a pyramid-shaped structure formed of a single sheet of foldable material, such as a sheet of paper. Two embodiments are disclosed. The first embodiment maximizes the amount of volume contained by the pyramid-shaped structure. The embodiment encloses a smaller volume than the first embodiment but maximizes structural strength, or rigidity, of the structure. Each embodiment has certain advantages. The first embodiment can be efficiently created with a minimal number of folds. It can be "collapsed" from a single sheet of pre-creased material to instantly form a structure. It is also easily opened in a single motion. The second embodiment provides an extremely strong pyramid structure that can be formed around an object for complete containment of the object. Other uses are possible such as providing a tent-like housing for a person by cutting an opening in one of the sides.

  • Patent number: 5605278
    Abstract: A carton for a package of photographic film, such as instant film. The carton is formed of a unitary paperboard blank coated on both sides by a thermoplastic barrier film. The thermoplastic functions as an adhesive when acted upon by heat and pressure, thus sealing portion sof the blank together. Each of four corners of the carton includes a gusset folded in such a manner as not to present a raw paperboard edge to the interior. The construction yields an air tight, liquid tight package with an oxygen barrier, and obviates the requirement of many similar packages that the photographic film be separately wrapped in a protective foil or film prior to being placed in a catron. Three embodiments of the carton are disclosed.

  • Patent number: 5522537
    Abstract: A carton has a top wall having eight side edges which circumscribe a top wall surface area and a bottom wall having four side edges which circumscribe a bottom wall surface area. Four trapezoidal side walls, each having a major edge, a minor edge and two side edges, extend between the top wall and the bottom wall, such that the major edges of the sidewalls abut, respectively, adjacent of the side edges of the bottom wall and such that the minor edges of the sidewalls abut, respectively, alternate of the side edges of the top wall. The carton has four triangular corner wall portions, each having a base, which abuts the top wall at a position displaced inwardly from one of the top wall edges that does not abut one of the minor edges of the side walls, and two sides, one of which abuts one of the side edges of one of the adjacent side walls. A device for opening the carton is positioned in one of the trapezoidal side walls, and a line of weakness is positioned in the bottom wall or in the top wall.
