Definitions

  • This invention relates to heavyweight packaging, and more particularly to a reinforcing member for providing structural integrity to a container adapted to ship, store and handle large objects.
  • Heavyweight packages are known in the prior are for packaging such things as vinyl fence products, cultural stone, lawn mowers, farm equipment, ATV's, jet skis, motorcycles, bulk food products, produce, poultry, raw food ingredients, textiles, and the like.
  • Conventional packages may comprise enclosed boxes, or spaced frame members that only partially enclose the product but provide support, particularly when shrink- wrapped with the product, to enable stacking and handling, or boxes that are reinforced with spaced frame members.
  • the spaced frame members in particular, may be made of wood, plastic, corrugated cardboard, or any combination of these. Reinforcing corner posts of wood, corrugated cardboard, paper tubes, or solid fiber angle boards are commonly employed to improve the compression strength of the boxes, for example.
  • Wood is subject to pest infestation, is potentially unsafe during handling, and presents problems with disposal.
  • Plastic and laminated containers are costly, and paper tubes and angle boards often have high-recycled content, negatively influencing their performance.
  • Corrugated corner posts often can provide adequate compression strength that is cost-effective, without the potential problems encountered with some of the other materials.
  • conventional corner post styles and materials are often costly, hard to form into position, and may not remain in place during the life of the package.
  • the present invention is a corner post for forming a package to contain a product, especially large, heavy or bulky items, to improve the stacking strength and resistance to distortion of the package.
  • the corner post of the invention is inexpensive, easy to form into position, and remains in place during the life of the package. It is formed from a unitary blank of corrugated material, and comprises panels that fold 180° onto one another to form double thickness panels that are then folded into 90° relationship with one another to form an angle-shaped reinforcing corner post that is self-locked in the 90° folded position.
  • the corner post of the invention preferably comprises a unitary blank of corrugated board divided by spaced parallel scores into at least four panels of substantially equal width.
  • Panels one and four fold 180° onto inner panels two and three, respectively.
  • Panel one has notched areas along its edge opposite that connected with panel two, and the notched areas line up with slots in panel two adjacent the score between panels two and three.
  • Panel four has tabs along its edge opposite that connected with panel three, and the tabs lock into the slots of panel one and the notched areas of panel two when the folded-together panels one and two are folded 90° with respect to folded-together panels three and four, securing the panels in the 90° folded position.
  • Panels one and four may be laminated to respective adjacent panels two and three to enhance the compression strength of the corner post.
  • the post can be stored in a flattened condition, or folded 90° in to the angled shape.
  • Lamination together of the panels can be accomplished by use of adhesive, stitching, tape, or other suitable fasteners.
  • Top and/or bottom flanges may be provided on the post.
  • a bottom flange could be utilized to secure the post to a pallet, and self-locking means on the top and/or bottom flange could be used to achieve complete pre-assembly of the post.
  • the post of the invention also could be made from a six-panel blank of corrugated, die-cut with panels folding 180° and forming two 45° comers.
  • a die-cut cross beam can be provided for attachment between the upper ends of two adjacent comer posts to hold the comer posts in position against the product while the comer posts and product are being shrink wrapped or banded.
  • the cross beam can have flanged ends which fold over the product and overlap with one another, forming multiple thicknesses of the cross beam and comer posts, or the flanges can be triangularly shaped so that they do not overlap when folded inwardly over the product, or the flanges can be omitted.
  • the comer post of the invention can be stored and shipped in a flattened condition, and the self-locking means enables the post to be folded and locked and held in operate position without requiring the use of separate fasteners such as staples, tape, glue, or plastic grommets.
  • the ability of the panels to fold 180° increases the top-to-bottom compression strength by increasing corrugated material in strategic areas within the package.
  • a container reinforcing member formed from a blank comprising: a plurality of spaced-apart, substantially parallel score lines dividing the blank into at least four panels, the at least four panels including a first panel, a second panel, a third panel and a fourth panel, the first panel being foldable over the second panel to define a first leg of the member, the fourth panel being foldable over the third panel to define a second leg of the member; one or more tabs projecting from a side edge of the first panel; one or more slots provided in the third panel, at least one of the slots being positioned to receive one of the one or more tabs when the first panel is folded over the second panel; and, one or more notches provided in a side edge of the fourth panel, at least one of said notches being positioned to receive one of the

  • a container for containing a product comprising: a base for supporting the product; and, one or more reinforcing members supported by the base and positioned thereon to surround the product, at least one of the reinforcing members comprising a first leg and a second leg disposed perpendicularly to the first leg, the first leg including a first panel folded over a second panel, the second leg including a third panel folded over a fourth panel, the first panel having one or more tabs projecting therefrom for engaging one or more slots provided in the third panel.

  • the post is adapted to be supported at a comer of a package P to form an economical package frame having good stacking or compression strength.

  • the first and fourth panels comprise outer panels of the blank, and the second and third panels comprise inner panels.
  • a plurality of notches 20, 21 and 22 are formed along the outer edge of the first panel 16, resulting in a plurality of uniformly spaced outwardly projecting edge portions 23 on panel 16.
  • a plurality of slots or openings 24, 25 and 26 are formed in the second panel 17 adjacent the score between panels two and three, and a plurality of spaced tabs 27, 28 and 29 extend outwardly from the outer edge of fourth panel 19.
  • a modified comer post 10' may have flanges 30 and 31 on one or both ends, as depicted in Figures 11 and 12.
