Definitions

  • the present invention relates generally to packing materials and, more particularly, to packing materials used for void fill, blocking, and bracing.
  • the article When shipping an article from one location to another, the article is typically placed in a container along with protective packaging material to fill the voids about the article, to cushion the article and or to brace the article during the shipping process.
  • protective packaging material to fill the voids about the article, to cushion the article and or to brace the article during the shipping process.
  • Paper may be used as a packing material. Some examples of this are tissue, news print and kraft paper. Paper is less durable than foam products and foam "peanut" products generally lacks the ability to prevent migration of articles in a box, in addition to the fact that the plastic in foam products is not easily biodegradeable, and that foam products often also require as much room for storage as they take up in use.
  • Cohesive coated products may be used when more protection is needed than paper alone can provide.
  • a cohesive-coated material contacts another cohesive-coated material, the respective cohesive-coated portions adhere to each other.
  • the use of cohesive coated strand packing material require a heavy and expensive machine that slits the raw packing material on demand.
  • a machine cuts the paper into strands as it is dispensed.
  • Such material may be referred to as cohesive-coated strand paper.
  • the machines needed to dispense this paper are heavy, and contain expensive slitting blades that provide only a single fixed width of strands.
  • Packaging equipment manufacturers make machines that are designed to convert sheet paper into a packaging material for packaging applications.
  • the conversion machines typically are not capable of dispensing strand packaging material as they do not have the ability to slit paper into strands on demand, limiting their versatility. Summary
  • manufactures may be composed of a sheet stock material intermittently slit in a lengthwise direction in a plurality of laterally-spaced longitudinal rows that define strands therebetween, with at least one face of the sheet being coated with a cohesive.
  • the paper may be composed of 50 pound basis-weight kraft paper approximately 7.5 inches wide (about 19 cm), coated on one side with a cohesive, such as a latex cohesive, with a number of non-continuous slits present in the paper sectioning the paper into strands approximately 1 .5 inches wide (about 3.8 cm).
  • Each slit being interrupted in approximately 4.25 inch (about 10.8 cm) increments.
  • the interruption may be approximately 0.125 inches (about .3 cm) in length and forms a bridge that connects adjacent stands together.
  • the interruption in the slits may be equally staggered between the strands and continuously repeated along the length of the roll.
  • An operator loads a roll of pre-slit strand packaging material onto a machine, not typically associated with dispensing cohesive strand packaging material, and feeds it through the machine.
  • the machine's features may include a paper feeding mechanism, a guillotine cutter, safety mechanisms, paper shaping mechanisms and features, and a user interface and/or computer to aid in dispensing strand packing material from the machine.
  • the cohesive- coated strands may be randomly tangled to come into contact with other cohesive-coated strands.
  • cohesive-coated strand comes in contact with another cohesive-coated strand they cohesively adhere to each other.
  • Many locations of adhesion are formed as the paper is manipulated. The formation of adhesion sites give structure and resiliency to the packing material and allows it to retain a molded shape.
  • the material may be formed into the rough size and shape relative to packaging needs and then may be further shaped by the article to be protected and the box in which both the article and the packaging material are placed.
  • the mass of paper with many interconnected cohesive adhesion sites protects the article from physical surface abrasion and general structural damage.
  • two or more sheets from two or more rolls may be loaded into the machine.
  • the amount of paper dispensed is increased and the density of the packing material can also be increased.
  • the addition of sheets increases the compressive load- carrying ability of the resulting packing material.
  • a single roll of paper or multiple rolls of paper, or one of multiple rolls of paper may have volatile corrosion inhibitors present.
  • the width of the roll may be adjusted to make it more suitable for the particular machine it is to be dispensed through.
  • the width of the strands may be about one sixteenth of an inch or greater up to about half the width of the sheet.
  • the number of slits may be adjusted to suit specific packaging needs. In general, as the number of slits or strands increase the compressive load carrying ability of the packing material decreases making it more formable and more apt to protect delicate products. As the number of slits deceases the compressive load carrying ability of the packing material increases making it better suited for heavy objects.
  • the size of the uncut bridge portions between slits may vary. Increasing the size of the bridges increases the compressive load carrying ability of the packing material making it better for heavy objects. Decreasing the size of the bridges makes the material more formable and more suited to protect delicate products.
  • the pattern of bridges between the strands may be other patterns such as chevron or a straight transverse line.
  • the frequency of bridges may vary. Increasing the frequency of the bridges increases the compressive load carrying ability of the packing material. Decreasing the frequency of the bridges makes the material more formable and more suitable to protect delicate products.
  • plastic sheet, foam sheet, bubble wrap or other sheet good may be used instead of paper.
  • the width of strands, frequency of bridges and length of bridges may be adjusted for the media, intended article to be packed, and the box it is to be placed in.
  • plastic or foam sheet may be made from petroleum, from renewable sources or otherwise may be biodegradable.
  • the paper may range from about one inch wide (about 2.5 cm) to a few feet wide (about 91 cm). Narrower widths being better suited for small items. Widths of a few feet wide being better suited for large industrial components or machines. Wider widths have the additional advantage of decreasing the time needed to pack an article.
  • the basis weight of the paper may range from about 13 pounds (about 6 kg) to about 80 pounds (about 36 kg).
  • the heavier weight paper being stiffer and increasing the compressive load carrying ability of the packing material making it better for heavy objects.
  • the lighter weight paper being more formable and more suitable to protect delicate products.
  • the sheet of universal feedstock of strand packing material with cohesive may be perforated at regular intervals of about 12 inches (about 30.5 cm) to make is more compatible with existing paper dispensing machines that may not have a cutting mechanism.
  • the perforations can range from about 1 inch (about 2.5 cm) to 20 feet (about 6 m) apart
  • the perforations may be a repeating pattern of various lengths. For example a perforated section 2 feet (about 61 cm) long, a perforated section 3 feet (about 91 cm) long and a perforated section 4 feet (about 122 cm) long which is then repeated along the length of the roll.
  • a machine may be built intentionally for use with rolls of pre-slit strand cohesive paper allowing the overall cost and or complexity of existing machines for dispensing strand packing with cohesive to be decreased. Such a machine could replace the expensive slitting mechanism with more cost effective feed rollers. The simplification would not only decrease the cost of parts but would also decrease the time required to build and service the machine. In other embodiments the machine may be powered or manually operated.
  • a box with cohesive on the interior surfaces may be used in conjunction with presplit strand packing material with cohesive.
  • presplit strand packing material with cohesive may be used in conjunction with presplit strand packing material with cohesive.
  • this embodiment not only does the shape of the wad of packing material relative to the box and the article hold it in place but also the cohesion between the wad of packing material and the interior of the box further limiting migration of all items in the box.
  • a method of using a universal feedstock of strand packing material for block and brace protection may include loading a roll of universal feedstock of strand packing material into a paper dispensing machine lacking the ability to slit strand packing material on demand and using the machine to dispense strand packing material.
  • the machine may be motorized or manually operated. After being dispensed an operator then receives strand packing material from the machine and begins shaping the stand packing material into a bundle, pad or wad of interconnected strands forming a semi-ridgid support structure.
  • the wads of strand packing material may be formed by loosely mixing strands after they are received by the operator from a dispensing machine and shaping the strands into a wad of the approximate size needed relative to the size and weight of the part and the size of the box.
  • the wad typically may have a roughly spherical shape, but may be elongated or be other shapes.
  • the wad is placed at corners, edges, ends and or other critical points of an article to support and or suspend it in a box. As the wads are placed, on the article and in the box, they deform and conform to the article and the box forming a semi-rigid support structure between the article and the box.
  • two wads may be used to support either end of the article and the center section of the article left unexposed. When packing cylindrical articles this way the wads on either end may be called end caps and they support the article preventing it from structural damage during shipping.
  • the number of wads may be adjusted so that they collectively support the article in the box, and may prevent the article from touching any sides of the box. For example, if the article is roughly cubic in shape eight wads may be used to support the eight corners of the article. The intent is to support the article at critical points preventing its unintentional movement. Supporting the article at critical points allows for cost effective use of material.
