Definitions

  • the invention relates to a packaging structure, a packaging system and a corresponding method to apply such a packaging structure for shock-absorbing packaging of equipment.
  • a large variety of equipment is shipped over long distances. Fragile goods or sensitive equipments have to be secured against mechanical impacts acting on the equipment during shipment. Therefore the equipment is commonly enclosed with packaging material to absorb an eventual mechanical impact, e.g. with different kinds of foam arranged between container wall and goods.
  • packaging material to absorb an eventual mechanical impact, e.g. with different kinds of foam arranged between container wall and goods.
  • foam can easily being damaged and subsequently the reliability to absorb shocks might vanished. Additionally this packaging material is commonly a one-way-material. Foam and carton parts eventually glued together prevent recycling of the packaging material.
  • there is strong demand to save resources and subsequently to provide packaging material usable frequently and enabling recycling.
  • a packaging structure for shock-absorbing packaging of equipment comprising at least a first cell and a second cell, which is gastight separated from the first cell, the cells are inflated with a gas, preferably air, each cell comprising multiple connected tubular cavities arranged essentially parallel to each other in a comb- shaped structure, where the comb-shaped structures of the at least first and second cells are interlocked and each tubular cavity of the first cell is mechanically joined to the neighbored tubular cavity of the second cell establishing a first mat of mechanically joined tubular cavities to enwrap the equipment to be transported
  • the shape of the packaging structure do not has to be adapted to a certain shape and/or size of the equipment to be transported.
  • the packaging structure can be used for any shape or size of the equipment strongly reducing the manufacturing costs for such packaging material since there is no demand to provide several different types of packaging material.
  • the use of one type of packaging structures for all kinds of equipment strongly reduces the packaging logistic effort since the shipping centers have to have only one type of packaging structures on stock. Situations, where equipment cannot be shipped, because the required packaging material is not present, can be fully avoided.
  • the manufacturing of this packaging structure will be more efficient, because the manufacturing machines for this packaging structure can be standardized and there will be only one type of machines being required resulting in lower manufacturing costs for this packaging structures.
  • the mat of mechanically joined tubular cavities provides an air balloon structure to prevent the equipment from mechanical impacts during transportation suitable to wrap heavy and large equipment.
  • the at least two separated cells provide a shock-absorbing structure even if one of the cells is damages and/or comprises a leakage, where the inflated gas leaves the cell leading to a deflation of the particular cell.
  • the redundancy of the shock-absorbing structure is further improved by increasing the number of gastight separated cells. In case of three cells, two cells might be damaged without losing the shock-absorbing character of the packaging structure.
  • Packaging structures with four or more separated cells provide packaging structures with an exceeding reliability to protect the wrapped equipment.
  • the gas pressure inside the inflated cells is at least 1 atm, preferably, the pressure is above the pressure of the environment to provide a reliable shock-absorbing character of the packaging structure.
  • the gas pressure inside the cells is 2 atm.
  • a standard pressure of 1 atm corresponds to 1 ,01325 bar.
  • the applied gas to inflate the cells may be any suitable gas, e.g. air, nitrogen etc. Air will be applicable without any effort and is therefore the cheapest applicable gas. However, noninflammable gases such as nitrogen as gases for inflating the cells might be advantageous in case of transporting equipment requiring additional security effort.
  • each of the cells has at least one closable valve suitable to inflate gas into the cell. This allows to adjust the pressure inside the cells to the demanded pressure value to provide an optimized shock-absorbing property adjusted to the size, weight and shape of the equipment to be transported.
  • the valve is also suitable to remove gas from the cell enabling multiple inflation and removable of gas.
  • the packaging structure can be reduced in size by removing the gas from the cells. The packaging structure can be folded into a small package and returned to an equipment distribution center to be used to enwrap the next equipment to be shipped. Multiple use of the packaging structure up to 100 times is possible.
  • Suitable valves are for example check valves as used in bicycle tires, preferably a double check valve for easy removal of gas out of the cells of the packaging structure. These valves are suitable for gas pressures up to 6 bar. Alternative so-called Sclaverand valves suitable for gas pressure up to 15 bar may also be used.
  • the cells of the packaging structure may be inflated manually with a hand pump or automatically on an inflating station adjusting the gas pressure to a certain desired pressure value. People skilled in the art may choose other suitable valves within the scope of this invention
  • the cells of the packaging structure are made of a resin material.
  • Resin material can be easily recycled by returning the resin to its raw material state. This recycle process of returning old packaging structures to raw material and manufacturing new packaging structures out of this raw material can be applied up to 40 times, which strongly reduces material waste disposal.
  • the environmental relevant total C0 2 emission for these packaging structures in its entire life cycle is significantly reduced to 3% of the C0 2 emission of corresponding conventional packaging materials (such as foams). This value is based on C0 2 release for manufacturing of the packaging material and its waste disposal. Multiple use and recyclability strongly reduces the environmental relevant total C0 2 emission of the packaging material.
  • the resin material comprises polyamide, polyethylene and reinforced nylon being resistant against stretching of the material.
  • the number of damages (leakages of one of the cells) of the packaging structure of this material is strongly reduced leading to a strongly increased reliability of this packaging structures compared to conventional packaging structures.
  • This material even large equipment such as servers of weights of 1 metric ton can be wrapped and shipped in a shock- absorbing packaging.
  • This packaging structure is able to provide a shock-absorbing packaging of equipment of weights up to 5 metric tons.
  • the claimed resin material is even applicable under unstable pressure conditions as present during air transports (in planes), where the environmental pressure may decrease below 1 bar, e.g. down to 0,79 bar.
  • the packaging structure further comprises at least a second mat of tubular cavities mechanically connected to the first mat, preferably along a connection line, in order to increase the number of gastight separated cells connected to each other to enwrap the equipment to be transported.
  • the setup of the second mat is preferably identical to the first mat, where the second mat comprises a third and a fourth cell, which is gastight separated from the third cell, the cells are inflated with a gas, preferably air, each cell comprising multiple connected tubular cavities arranged essentially parallel to each other in a comb-shaped structure, where the comb-shaped structures of the third and fourth cells are interlocked and each tubular cavity of the third cell is mechanically joined to the neighbored tubular cavity of the fourth cell establishing a second mat of mechanically joined tubular cavities.
  • the mechanical connection is established between the second cell and the third cell at the side of the cells being essentially vertical to the long side of the tubular cavities.
  • the mechanical connection is preferably established via a connection line arranged between the second and third cell, which could be rigid or flexible.
  • the first and second mat may be arranged in one plane or on top of each other or with the flexible mechanical connection along the connection line between first and second mat enabling to arrange the first and second mat in one plane to increase the area of the packaging structure or to arranged both mats on top of each other in order to enhance the shock-absorbing properties of the packaging structure.
  • the packaging structure comprises at least one first connection means and at least one second connection means suitable to provide a connection to the second and first connection means of another packaging structure along a first direction in order to provide a tight fit of the packaging structure on the equipment.
  • Two packaging structures can easily be connected to each other to enwrap both sides of an equipment to be shipped, either front side and back side and/or left side and right side of the equipment. The directions back/front and left/right shall be understood in the sense of an upright standing equipment, e.g. a computer server.
  • the first and second connection means may be any suitable means to connect two packaging structures together, e.g. clips, clamps, fasteners or belts and the corresponding counterparts to apply this means such as holes, slits, recesses etc. People skilled in the art may consider other first and second connection means suitable to provide a connection to the second and first connection means of another packaging structure along a first direction in order to provide a tight fit of the packaging structure on the equipment.
