Definitions

  • a pallet is a portable, horizontal, rigid, platform used as a base for assembling, storing, stacking, handling goods as a unit load.
  • Conventional pallets are typically constructed of wood and are made by stapling or nailing a number of boards (known as “deckboards") at their ends to a number of continuous solid boards (known as “stringers").
  • deckboards a number of boards
  • stringers continuous solid boards
  • the upper set and lower set (where used) of deckboards thereby form an open area defined by the thickness of the stringers. This opening is used to accommodate a fork lift or hard truck. In this way the pallet may be moved from place to place by lifting the pallet and its load off the floor.
  • My invention is a pallet constructed of paper involving a central platform or deck constructed of a honeycomb filler bounded on the top and bottom surfaces by corrugated sheets.
  • the corrugated sheets are positioned so that the corrugations of flutings are not parallel. Additionally, the corrugated sheets may be folded over the edges of the honeycomb core and fastened to the other side. Runners are included to support the central platform.
  • my design may be completely recycled as paper without separation into constituent parts.
  • U.S. Pat. No. 3,661,099, to Shelor shows a paper shipping pallet having a deck having a core section made of small strips cut from single, double, or triple wall corrugated paper board sheet stock glued face to face. Sheets of corrugated are glued to the longitudinal edges of the composite core.
  • the core and facing sheets are desirably of a specific size of corrugated sheets, i.e., having a size "A" flute or better.
  • the legs of the pallet appear to be wooden blocks.
  • U.S. Pat. No. 3,650,459, to Tucker, shows a paper pallet design involving a folded corrugate sheet as the cargo support area. That cargo deck is provided with a number of pallet feet (which operate as spacer blocks within the cargo deck) made of molded plastic material such as polystyrene. The use of a honeycomb core within the cargo support area is not disclosed.
  • U.S. Pat. No. 3,952,672, to Gordon et al shows a disposable pallet made of a single folded corrugated sheet. The use of a honeycomb core on the cargo support area is not disclosed.
  • U.S. Pat. No. 4,790,249, to Webb shows a pallet design in which the cargo deck is made up of facing sheets separated by a number of blocks having a specific design.
  • the block design involves a cellulosic material glued together by a bonding material (such as ureaformaldehyde) all extruded into the shape of a box beam.
  • the boxes are positioned so to protect the deck from the tines on a fork lift.
  • Netherlands Patent Application 83-00024 shows an interesting design for a paper pallet.
  • the cargo support deck appears to be constructed of a number of loops of paper glued together at a number of sites within the deck and also glued to a periphery forming the edge of the deck. Neither the use of a honeycomb core nor the use of corrugated sheet in the cargo deck support area is disclosed.
  • U.S. Pat. No. 4,319,530, to Moog discloses a pallet, said to be disposable, having a cargo supporting deck area made up of a central core of a honeycomb made of laminated corrugate.
  • the core is faced with one or more corrugated sheets glued to the core.
  • the facing on the cargo support surface of the central core may be made up of multiple layers of corrugated sheets. Although these multiple facing layers are said to be positionable so to permit "cross laminating where the flutes of the different sheets are oriented at right angles", there is no suggestion that use of corrugated sheets on alternate sides of the core positioned so that the flutes are not parallel is useful. Further, the disclosure is silent on the use of a corrugated sheet folded over the edge of the central core and fastened to the opposite side nor, obviously, is any benefit accorded such a folded sheet.
  • US-A-3709161 on which the precharacterising portion of appended claim 1 is based, discloses a load carrying pallet made from a honeycomb slab of sheet material and provided with slits in walls of some cells to define weakened regions that can be readily displaced to form channels for the fingers of a fork lift truck.
  • a pallet with a deck comprising:
  • a pallet as might be used to support cargo during that cargo's transportation or storage.
  • the pallet is constructed of paper.
  • the pallet design involves a central platform or deck constructed of a honeycomb filler bounded on the top and bottom surfaces by corrugated sheets. To enhance the torsional and deflective strength of the central platform, the corrugated sheets are positioned so that the corrugations are not parallel. Additionally, the corrugated sheets may be folded over the edges of the honeycomb core and fastened to the other side.
  • Figure 1 is an exploded drawing of some of the components used with the invention.
  • Figure 2 is a drawing showing the invention using runners to support the cargo deck.
  • Figure 3 is an exploded drawing of another variation of the invention.
  • this invention is a pallet a might be used to support cargo during that cargo's transportation or storage.
  • the pallet is constructed of paper.
  • the pallet design involves a central platform constructed of a honeycomb filler bounded on the top and bottom surfaces by corrugated sheets. To enhance the torsional and deflective strength of the central platform, the corrugated sheets are positioned so that the corrugations are not parallel. Additionally, the corrugated sheets may be folded over the edges of the honeycomb core and fastened to their opposite side. Runners or legs, particularly those utilizing honeycomb or corrugate cores and corrugate skins and adapted so that the skins overlap up on to the edges of the central platform, may be included to support that central platform.
  • the invention may be made of a variety of materials, I prefer to construct the pallet from materials which may be readily recycled using commercially available technology.
  • the various sheet material is desirably from kraft paper or other similar paper stock.
  • other materials may be selected, e.g., MYLAR, polyethylene, polypropylene (clear or fibrous paper product), or the like is acceptable.
  • Some thermosetting polymeric materials are not currently widely recyclable and may not be the best of choices for the pallet from that viewpoint. However even with nonrecyclable materials the improvements of the pallet design will be apparent.
  • Choice of materials and methods to join together the various components of the pallet may also be made on the basis of recyclability. For instance, most water-based glues, e.g., hide glue, mucilage, etc. are glues compatible with the kraft paper recycling processes.
  • Heat sealing thermoplastic materials such as polypropylene is an expedient using no adhesive.
  • FIG. 1 is an exploded diagram showing some of the components used with the invention.
  • the central core (100) comprises an expanded honeycomb material.
  • Joined to this core on the upper and lower faces of the core are two facing sheets (102, 104). If the method for joining the two facing sheets to the core is properly carried out, the cells within the core are isolated from each other. The core strength is enhanced by the formation of these closed cells and imparts an amount of springiness and shock absorbing capabilities to the core.
  • Attached to the facing sheets (102, 104) are two corrugated sheets (106, 108).
  • the flutes on the respective corrugated sheets are depicted such that the flutes on sheet (106) are not parallel to the flutes on sheet (108).
  • the angle between the respective flutes may between about 30° and 90° although for a very practical pallet from the vantage of strength, versatility, and ease of construction, an included angle between the flutes of about 90° is desirable.
  • facing sheet (104), corrugated sheet (108), and sheet (112) and the combination of facing sheet (102), corrugated sheet (106), and sheet (110) are commonly available articles of commerce which may be employed in the invention.
  • This invention is not limited to the basic variation shown in Figure 1. Additional sheets of corrugated material may be added to the upper and lower faces of the combination shown in that Figure if additional strength is needed for some particular purpose. Addition of a sheet on the upper (or load-bearing face) is preferable to enhance the impact resistance of the pallet deck.
  • the pallet may be coated with a material which will harden or waterproof or dustproof the pallet. These materials may be chosen to meet whatever criteria are appropriate for the pallet use. For instance, if used in a humid atmosphere or used outside or are moved between refrigerated and non-refrigerated areas, waterproofing is desirable. Known water-based and oil-based materials may be applied as needed.
  • the cargo face of the deck may be covered with or coated with a suitable material to prevent slippage of the cargo.
  • Figure 2 shows a pallet made according to the invention. It is made of a top deck covered by a top sheet (302) of a corrugate sheet. It has an expanded honeycomb core (304) and an adhering lower skin (306) also of a corrugate sheet.
  • the runners (308) are made up of a corrugate tray (310) enclosing a portion of expanded honeycomb core (312).
  • the runners (308) are adhesively secured to the underside skin (306).
  • the runners utilize tabs (314) to allow sturdy attachment of the runners to the top deck assembly.
  • the Figure 2 embodiment is a design known as a two-way entry pallet.
  • the wide slots between the runners on the underside of the cargo deck permit entry of forklift or hand truck tines from either of opposite ends.
  • a hard paperboard (316) may be glued to the bottom of the runner trays (310).
  • the paperboard is typically one-fourth to one-half inch in thickness and made form thin sheets of paper glued and compressed together to give a hard surface to the bottom of the runners.
  • the hard surface prevents the bottom of the corrugate trays from depressing around the conveyer roller and thereby preventing the load-bearing pallet form rolling easily down the conveyer.
  • the hard paperboard provides adequate hardness for reducing the compressibility of the runner bottom and therefore reduces the drag on the pallet.
  • FIG 3 shows a variation of the pallet shown in Figure 2 but in which the lower corrugate sheet is integrated with the runner tray to enhance the overall strength of the runners.
  • the deck includes an expanded honeycomb core (402) and an upper face (404) of corrugate.
  • the runners and the lower deck facing are made of a set of runner cores (406) of expanded honeycomb or multilaminated corrugate and a lower folded corrugate sheet (408).
  • the lower corrugated folded sheet (408) adheres to and encloses the runner core blocks (406). It also has tabs (410) which may be folded over and allow it to adhere to the cargo (or upper) surface of the upper corrugate face (404).
  • the upper corrugate face (404) adheres to the honeycomb core (402) by use of adhesives, glue, or solvents and also has tabs (412 which may be folded under the runner core blocks (406) and tabs (414) which may be folded under the honeycomb core (402).
  • the runners obviously cannot be separated from the deck without the virtually complete destruction of the pallet.
  • This example demonstrates the strength of the pallet deck made according to the invention by comparison to decks made in other ways.
  • a series of pallet decks were constructed using expanded honeycomb as a core.
  • the core was glued to the core using an industrial mucilage, approved by the FDA for use with foodstuffs.
  • Each core was about four foot by four foot.
  • the core was a 1-1/2 " thick expanded honeycomb of 33 lb. paper arranged into 1/2" cells.
  • the first deck (Deck "A") was made using a good grade of paper, i.e., 42 lb. kraft paper, as the upper and lower skins on the core. The paper did not cover the edge of the core.
  • a second set of two identical decks (Decks "B” and “C") was made using corrugate skins (200 lb. test corrugate) in which the flutes in the skins were parallel to each other. The skins were glued to the honeycomb core. The edges of the core were not covered.
  • a fourth deck (Deck “D") was made in the same fashion a Deck “C” using corrugate skins in which the flutes were at right angles to each other. The edges of the core were not covered.
  • This deck is in accord with the invention.
  • a fifth deck (Deck “E") was made also in accord with this invention in the same fashion as Deck “D” except that one skin was wrapped around the edge of the core and glued to the other skin.
  • Each of the decks was mounted on a testing table. The approximately two feet of the decks overhung the edge of the table. The end of the deck on the table was securely clamped to the table. The edge overhanging the floor was loaded with increasing weights until the deck bent at the edge of table and sustained a 15° bend.
