    Title of Invention
    A packaging element for use in packaging of an unmounted product for use at a roof, and a method of use of same.
    Technical Field
    The present invention relates to method for packing a pre-assembled and pre-packed product for use at a roof in second packaging means, and to a second packaging for a pre-packed product for use at a roof.
    Background Art
    Once a product for use at a roof such as a roof window, a flat roof window, a skylight, a roller shutter or similar building product is assembled, the final product is typically packed in a cardboard packaging and stored in an upright position ready for shipment. Such a packaging is known from e.g. the applicant’s earlier application PA 2015 70503 and PA 2011 70546. Such cardboard packages are traditionally designed as flat rectangular box-shaped carton packages and are known in many different designs. In many applications the products to be handled are of a substantial size, e.g. building products having a length, width and height of 60-180cm x 50-120cm x 10-20cm and weights ranging between 40-100kg or heavier. In order to secure a sufficient strength to the package for the protection of such a building product during handling of the package, including transportation and storage, it is often necessary to stiffen or reinforce the package in various ways, e.g. adding inner packaging elements or increasing the wall thickness of the carton. This, however, increases the weight and becomes more expensive. Most often, shipments are large enough so that several packed products for use at a roofs are juxtaposed and crane-loaded and unloaded together. This juxtaposing contributes to each product and each packaging not being damaged during shipment.
    In rarer situations, shipment size consists of only one or two units. In these cases, a more robust packaging is required to ensure safe delivery of
    DK 2018 70464 A1 the few units at destination, given the lack of the juxtaposing effect. Small drop-sizes, especially, generate high costs in the event of incurring damages because of the low income to shipping cost ratio compared to large dropsizes. However, more robust packaging brings its own disadvantages, since additional recourses need to be allocated to estimate how many products for use at a roofs should be packaged in an alternative packaging. In addition to the direct increased labor costs, such an approach inevitably leads to decrease in profitability when said estimates are erroneous and when the cost of implementation of new production lines is taken into account.
    When only few units are to be handled, handling is typically done by hand, since mechanical handling becomes cumbersome and costly. When handled by hand, however, the risk of items being dropped increases and therefore so does the risk of packaging and products incurring damages.
    An additional concern is package size, since even a slight increase in thickness of each individual packaged unit results in a great increase in the shelf space requirement before and after shipment. The space occupied by the unused packaging is also a concern for the same reasons.
    Honeycomb and other composite constructions such as waffle, cell and corrugated constructions of paper or cardboard are known to be relatively compact, lightweight and resistant to compression and torsion forces from for example DE102007021520. Here the honeycomb construction is made of paper or another material and filled with a plastic foam. Thus, recyclability is diminished, because this composite element must be separated into its individual parts to be disposed of correctly. As a result, recycling costs rise and negatively impact a company's profitability. DE102015109972 describes a composite packaging sheet with an expanded honeycomb core structure, which is covered with an upper and/or a lower corrugated cardboard sheets. The connected honeycomb core and corrugated cardboard sheet structure confers high strength and rigidity to the sheet. WO2014048544 relates to edge protection for edge-sensitive transported goods consisting of a yieldable material, such as foam-plastic, and a reinforcement layer, such as wood,
    DK 2018 70464 A1 making construction of this solution complicated and therefore expensive. Honeycomb inserts made of cardboard or cardboard/corrugated board are contemplated to prevent scratching of the outer surfaces of transported goods such as glass. DE202016002903 (U1) describes a folding card- board/honeycomb blank for forming a transport container adapted for receiving a push-through end portion of a loading pallet. US5605229 and
    EP0164631 contribute similar solutions.
    Summary of Invention
    It is therefore the object of the invention to provide a method for packing a pre-assembled and pre-packed product for use at a roof in removable second packaging means, said method permitting time efficient packing. It is also the object of the invention to provide a packing method of a prepacked product for use at a roof that will result in light-weight, effective and durable protection means. Yet another object of the invention is to provide a second packaging that is cost-efficient to manufacture, space-efficient to store and cost-efficient to recycle.
    At least one of the aforementioned objects is met by a first aspect of the present invention, whereby a method is provided comprising the steps of:
    • providing a pre-assembled product for use at a roof that is prepacked in a first packaging with at least one edge, • providing a second packaging comprising at least one packaging sheet having at least one groove on at least one of its sides arranged to allow for folding of the packaging sheet around said first packaging edge, • folding said packaging sheet around said first packaging edge, and • fixing said packaging to said first packaging.
    By said method being carried out with a packaging sheet having a groove on at least one of its sides, the folding of the packaging sheet around said a packaging edge may be facilitated. Said groove provides a weakened
    DK 2018 70464 A1 line along the length of the packaging sheet, which enables precise and easy folding of the packaging sheet so that two sides of the first packaging are efficiently contacted by the packaging sheet during packing. By “precise” it is meant that deviations of the fold are avoided by the groove, which predetermines the location of the fold, thus resulting in a straight fold line even if folding is attempted in inadequate positioning.
    In a preferred embodiment, the packaging sheet is a continuous, single-element sheet able to cover a surface larger than the first packaging. In this manner, the packaging sheet can be folded around the first packaging edges. In a preferred embodiment, two grooves are found on each packaging sheet, thus allowing two first-packaging edges to be covered with folding of the packaging sheet. Other embodiments are also contemplated, wherein three or four grooves are found, facilitating easy and precise folding of the packaging sheet around 2, 3 or 4 edges of the first packaging.
    In a preferred embodiment, said groove is arranged prior to use e.g. during manufacture. Such a groove may be cut out on the production line in an automated fashion that would result in a foldable packaging sheet end portion of sufficient length to effectively protect the side of the first packaging and remain in the folded position. In other embodiments, cutting of the groove is done manually prior to carrying out the method. In such cases, it is advantageous to include an indication of where the cut is to be performed, this being achieved by providing a marking e.g. in the form of a printed cutting-guide line.
    By fixing the packaging sheet to the first packaging, positioning of the packaging sheet is best guaranteed. In a preferred embodiment, fixing is carried out by the use of appropriate means such as pallet straps or tensioning straps. In another embodiment, the method of the invention is carried out by performing the steps of folding and fixing simultaneously. In such an embodiment, an adhesive layer, preferably including a release layer, is included on the outer surface of the outer cover layer. In this manner, the user can simulDK 2018 70464 A1 taneously fold and fix the packaging sheet on to the first packaging, thereby saving time.
    In another embodiment, the method further comprises the step of providing an incision in said packaging sheet arranged opposite an existing incision in said first packaging. By said incision in the packaging sheet, the functionality of the incision in the first packaging is maintained e.g. where the incisions are meant to provide attachment and lifting means. Such lifting means may be e.g. holes in which hands or devices for assisting in lifting may be inserted. Such incisions may be e.g. punch outs ready to be removed for the provision of said lifting means. With the additional surface created within said lifting means, lifting pressure is spread and more easily dissipated, thus making it safer, easier and more comfortable for the user.
    In another embodiment, the method further comprises the step of providing graphic design on said packaging sheet. By providing graphic design on the packaging sheet, important information can be immediately available to the user of the second packaging. Such information can be vital to the outcome of handling during transit. This is particularly relevant in the case of small drop-sizes, which are most commonly handled by hand and on a oneby-one basis. Said graphic design includes stickers, which may be appended after manufacture, and direct printing on the packaging sheet outer surface. Also considered to be graphic design is the provision of a cutting-guide marking for assisting in cutting a groove manually if not provided during manufacture. A pre-arranged groove may also be outlined by a marking to draw the user's attention to the purpose and location of the groove.
    In a second aspect of the invention, a second packaging for a preassembled product for use at a roof is provided. Said second packaging comprises at least one packaging sheet having at least one groove on at least one of its sides arranged to allow for folding of the packaging sheet around a first packaging edge.
    DK 2018 70464 A1
    In the previously mentioned first aspect, use of a second packaging according to this second aspect holds some benefits as described in the following embodiments:
    According to a preferred embodiment, said second packaging sheet comprises at least one of paper, cardboard, or polymer with a honeycomb, waffle or corrugated construction. Said constructions are lightweight and have excellent anti-compression strength in the direction of board thickness, tensile strength, and flexural strength. Production efficiency and cost might determine the choice of construction.
    According to some embodiments, the packaging sheet comprises at least one inner core layer made with said honeycomb, waffle or corrugated construction and at least one outer cover sheet. Said cover sheet is layered on top of the inner core layer and contributes to the overall strength of the packaging sheet by contributing tensile and shearing strength. In the case of incisions being made in the packaging sheet, the outer cover layer contributes to the packaging sheet not tearing when used.
    According to a preferred embodiment, the inner core layer is covered by two outer cover sheets, thus the core layer is sandwiched between the two cover layers, which lie on the outside of the packaging sheet structure.
    In a preferred embodiment, the outer cover layer is secured to the inner core layer with an adhesive. In other embodiments, the packaging sheet comprises an adhesive layer that fulfills the adhesive function between the inner core layer and the outer cover layer as well as further contributing to the strength of the second packaging.
    According to a preferred embodiment, the packaging sheet comprises an incision opposite an incision in said first packaging in the mounted condition. By said incision in the packaging sheet, the functionality of the incision in the first packaging is maintained e.g. where the incisions are meant to provide attachment and lifting means.
    In a further embodiment, the incision made in the packaging sheet is lined with an additional layer. Such a layer arranged around the edge of the
    DK 2018 70464 A1 incision provides reinforcement to the packaging sheet that increases shearing strength.
    Brief Description of Drawings
    In the following the invention will be described in more detail with reference to the drawings, where:
    Fig. 1 is an exploded perspective view showing two possible sandwich constructions of the packaging sheet,
    Fig. 2 is a section of a packaging sheet arranged on a first packaging before folding,
    Fig. 3 is a perspective view of a packaging sheet arranged on a first packaging after folding of the packaging sheet along the groove, and
    Fig. 4 is a section view showing a first packaging packed in a second packaging comprising two packaging sheets folded around the first packaging edges.
    Description of Embodiments
    Referring initially to Figs. 2 and 3, the general configuration of a second packaging 1 which is arranged to fold around the edges 31 of a first packaging 3 is shown. The second packaging 1 for a pre-assembled product for use at a roof packed in a first packaging 3 having at least one edge 31 comprises at least one packaging sheet 2. In the embodiment shown, the packaging sheet 2 is a continuous, single-element sheet comprising an end portion 25 and has two grooves 24 on one of its sides arranged to allow for folding of the packaging sheet 2 around said first-packaging edges 31. The groove is located on the opposite side to the first packaging 3 and separates packaging sheet 2 from end portions 25. Grooves 24 are close to a packaging sheet 2 edges, as shown in Fig. 2, and run essentially parallel to this. Prior to folding, the grooves are ideally aligned with first-packaging edges 31 so that packaging sheet 2 end portion may be easily folded over edges 31 by pressing them against said edges. As a result, end portions 25 will lie against
    DK 2018 70464 A1 a second side of first packaging 3 while covering edges 31, as shown in Fig.
    4.
    To ensure a good functionality of the invention and protection of the first packaging 3 from all directions, two packaging sheets 2 are used to cover two opposite sides and four corresponding edges of fist packaging 3, as also shown in Fig. 4.
    With alignment and folding having been carried out, second packaging 2 is fixed to first packaging 3 to ensure that packaging sheet 2 and end portion 25 stay in their intended position (not shown). Fixing may be carried out by any tethering means deemed appropriate for securing said second packaging onto the first packaging in a removable fashion, such as by using pallet straps, cords, foil, shrinking foil or other means. By “pallet straps” it is understood straps typical to the packaging industry, which may be made of steel, polypropylene, polyester, nylon, woven textile, paper, or any material or composite material deemed appropriate. Tension strength of said tethering means should be carefully adjusted to provide a satisfactory subjection without excessively penetrating the folded second packaging 2 and damaging the first packaging 3. It is evident to the person skilled in the art that this can be achieved routinely with standard packaging atomization machinery.
    In another embodiment, securing said second packaging to said first packaging is contemplated being carried out with the use of a weak adhesive. Such an adhesive should adhere with much greater strength to the underside of the packaging sheet 2 than it does to the first packaging 3, so that the adhesive remains attached to packaging sheet 2 when removing the second packaging 2 from the first packaging 3. Thus, a two-sided adhesive layer with different adhesive strengths on each side is contemplated. When such an adhesive is used, the steps of folding and fixing are carried out simultaneously, since no additional fixing means are to be applied.
    In the embodiment shown in Fig. 3, the shape and location of incisions 4 in the packaging sheet 2 are arranged to coincide with existing incisions in said first packaging 3 to e.g. provide holes for lifting by hand or by
    DK 2018 70464 A1 machine. Alternatively, an incision 4 of any appropriate size and shape may be performed according to need. In such cases, providing incisions of such a magnitude that the integrity of the packaging sheet 2 may be compromised should be avoided.
    A reinforcing layer, such as a layer made of e.g. a fibrous adhesive layer, may be used to line incisions.
    Also in the embodiment shown in Fig. 3, graphic design is provided to convey information to the user. The graphic design depicted in Fig. 3 is in the form of a sticker, but other methods, such as direct printing on the packaging sheet 2, are also contemplated.
    Turning now to Fig. 1, the packaging sheet 2 comprises a honeycomb construction 21 forming the inner core layer. Honeycomb and corrugated constructions are formed by strips of paper of cardboard or polymer folded and laid on their side, in such a way that they delimitate square, hexagonal or undulating cells, or other types of cells, with a depth dimension essentially perpendicular to the plane of the sheet. Waffle construction is achieved by introducing regular protrusions and subductions in the inner core layer. These constructions all offer good compression, torsion, shear and tensile forces to weight and volume ratios, thus being ideal materials for the packaging sheet 1.
    Still referring to Fig.1, the inner core layer 21 is covered by two outer cover layers 22. These are adhered to the inner core layer and contribute to the overall strength of the packaging sheet 2. Where additional resistance is desired, one or two additional adhesive layers 23 may be included between the inner core layer 21 and the outer cover sheets 22.
    It is known to the person skilled in the art that alignment of the second packaging elements 2 with the first packaging 3, folding of the packaging sheet end portions 25 and tethering of the second packaging to the first packaging can be achieved routinely with standard packaging atomization machinery.
    The invention is not limited to the embodiments shown and described
    DK 2018 70464 A1 in the above, but various modifications and combinations may be carried out.
