Definitions

  • the present invention relates to a holding element for use in packaging a product comprising a plurality of components having different size and/or geometry in a packaging unit, where a bottom side of the holding element is configured for being attached to an inner bottom surface of the packaging unit in such a way that the holding element is in contact with at least one of the components of the product, and where the holding element comprises protrusions, recesses and/or slots extending in one or more planes, which is/are parallel with the bottom side of the holding element.
  • the invention further relates to a packaging including such a holding element, to a method for making a holding element, and to a method for packaging a product using such a holding element.
  • Flashing assemblies typically comprise several components made of sheet metal, such as aluminium or copper, and components made from aluminium are typically painted and lacquered.
  • components of a flashing assembly will be at least partially visible in the installed state of the roof window product, it is important that they are not scratched or deformed. And even more importantly, a deformation is to be avoided as it may influence negatively on the weather proofing function of the flashing or covering components.
  • a further object of the invention is to provide a method for making an alternative holding element having a reduce climate footprint.
  • a still further object of the invention is to provide a method for packaging a product using such an alternative holding element.
  • At least one object is achieved with a holding element of the kind mentioned in the introduction, which is furthermore characterised in that the holding element is made from a paper-based material by folding and/or stacking.
  • At least one object is achieved with a method for making a holding element, where a paper-based material is folded and/or stacked thereby forming a bottom side and protrusions, recesses and/or slots extending in one or more planes, which is/are parallel with the bottom side of the holding element, said bottom side of the holding element being configured for being attached to an inner bottom surface of a packaging unit.
  • the product may for example be a flashing assembly for a roof window.
  • the paper-based material may for example be corrugated cardboard or honeycomb cardboard, and by folding and/or stacking it a three-dimensional shape suitable of serving as a holding element can be achieved with a minimal material consumption.
  • a further reduced material consumption may be achieved by designing one blank for a holding element configured to be folded in several different ways and/or by designing blanks so that they can be combined differently in stacks, thereby allowing different holding elements configured for use with different products to be made from the same blanks.
  • corrugated cardboard or honeycomb cardboard contains a small amount of adhesive, which will typically contain one or more polymers, the total amount of polymers used will be considerable reduced compared to the prior art blocks of EPS.
  • the holding element does not have to be separated from the packaging unit for recycling, since the packaging unit will typically also be made from cardboard and will thus belong to the same recycling fraction. This considerably increases the likelihood of the holding elements actually being recycled instead of just being disposed of as combustible waste. Moreover, pollution of the cardboard waste fraction, which has been known to result from EPS blocks not being separated from the packaging unit, is avoided.
  • a paper-based material may be biologically degradable.
  • Light-weight packaging items such as cardboard and EPS, are easily caught by wind when installing a roof window product on a roof of building and may end up in nature or other places where it cannot be collected by the installer. While it is of course not the intention to leave packaging material behind, a biodegradable holding element made from a paper-based material does little harm.
  • paper and cardboard are usually made from wood-fibres, other plant fibres, including fibres originating from straw, bamboo, bagasse, esparto, other grasses, hemp, flax, and cotton, may also be used, including combinations of different types of fibres.
  • a further advantage applying to the holding element made by folding is that it can be stored and supplied in an un-folded state, thus taking up considerably less space than the blocks used in the prior art. Unfolding of the holding element prior to reuse or recycling may also provide advantages with respect to space.
  • a third aspect of the invention relates to a packaging for use in packaging a product comprising a plurality of components having different size and/or geometry, which packaging comprises a packaging unit and at least one holding element as described above, said holding element being formed separately from said packaging unit and attached to an inner bottom surface of said packaging unit, the holding element being arranged in dependence of the geometry of the components of the product for separation thereof in such a way that at least one of the components may be retained from movement relative to the packaging unit in two directions being perpendicular to each other.
  • a fourth aspect of the invention relates to a method for packaging a product comprising a plurality of components having different size and/or geometry in a packaging unit, comprising:
  • one or more holding elements of the type described above in packaging a product comprising a plurality of components having different size and/or geometry and arranging it/them in dependence of the geometry of the components of the product for separation thereof allows a simply and reliable protection of the components with a minimal material consumption and hence a comparatively small climate foot print.
  • the holding element may be recycled together with a packaging unit if the packaging is also made from a paper-based material as is often the case.
  • Providing the holding element separately rather than forming part of the packaging unit and subsequently attaching it to an inner bottom surface of said packaging unit allows the same type of holding element and the same type of packaging unit to be used for several different products, by arranging the holding element in dependence of the specific product being packaged.
  • One blank for a holding element may potentially be folded in several different ways and/or blanks may be combined differently in stacks, thereby forming different holding elements configured for use with different products.
  • the method may further comprise fastening at least one of the components of the product to an inner bottom surface the packaging unit or to another component of the product, for example by adhesion, thereby supplementing the retention provided by the holding element(s).
  • the packaging unit is either a cardboard box or a blank, which is folded into a cardboard box once the holding element(s) has/have been fastened and possibly after arranging one or more components of the product thereon. It is, however, also within the scope of the invention to fasten the holding element(s) to a packaging sheet, which is then arranged in a cardboard box or on a blank for a cardboard box. It is even possible to arrange the entire content of the packaging on the packaging sheet before arranging the packaging sheet in the cardboard box or on the blank. The use of a packaging sheet may result in a reinforcement of the bottom of the packaging.
  • the holding element comprises a locking section or locking element retaining the holding element in the folded state.
  • locking elements are dots or lines of adhesive or mechanical fasteners, such as staples, snap-locking fasteners or hook-and-look type fasteners, such as Velcro ® .
  • locking sections are a flap folded into a recess in the holding element, an edge of the paper-based material fitting into a slot in the holding element, pairs of slot engaging with each other, and hook-shaped recesses or flaps engaging with each other.
  • the holding element comprises a bottom section, a first side section, a second side section, and a third side section, said bottom section forming the bottom side of the holding element, said first and second side sections being non-parallel and converging in a height direction extending away from the bottom section perpendicular thereto, and said third side section constituting a locking section retaining the first and second side sections.
  • the first and second side sections being non-parallel and converging in the height direction means that their mutual distance decreases with increasing distance from bottom section, possibly giving the holding element a triangular or trapezoidal shape when seen from the side in parallel to the bottom section and to the first and second side sections.
  • the third side section may be rectangular, such that its corners furthest from the bottom section project over the first and second side sections, thus providing a protrusion on either side of the holding element.
  • the third side section may be shorter than the first and second side sections, such that these protrusions are located closer to the bottom section in the folded state than the distal edges of the first and second side sections located furthest from the bottom section.
  • the holding element will have the overall shape of the letter A when seen from the side in parallel to the bottom section and to the first and second side sections.
  • This holding element is preferably made from corrugated cardboard.
  • the holding element is made from two or more layers of corrugated cardboard and/or honeycomb cardboard each having two major surfaces and one or more minor surfaces extending between them, said layers being stacked and interconnected with one or both of the major surfaces of each layer facing a major surface of another layer and with the major surfaces of all layers extending substantially in parallel.
  • One layer defines the bottom side of the holding element, and other layers may be made with different size and/or shape so that recesses or protrusions are formed on the holding element.
  • a slot may be formed between two layers by the layers being left unconnected at a section of their respective major surfaces.
  • a slot may for example be used for insertion of an edge of a component made from sheet metal, such as a component of a flashing assembly, whereby the component will be retained.
  • mutually opposite sides of the holding element extending away from the bottom side may be provided with identical protrusions, recesses and/or slots. This may for example allow identical holding elements to be used at both ends of an elongate product component without having to turn one of them. It may, however, also be advantageous that the mutually opposite sides of the holding element are provided with different protrusions, recesses and/or slots so that the same holding element may be used for different purposes by arranging it in different orientations.
  • the holding element is provided with a plurality of recesses, slots and/or protrusions, which can be used depending on the orientation of the holding element in relation to the packaging unit. Changing the orientation of the holding element will thus allow the use of the same holding element for different purposes, for example by protrusions of the holding element being arranged in different heights above the inner bottom surface of the packaging unit. A similar advantage may be achieved by providing a blank for a holding element, which can be folded in different ways depending on the intended use.
  • the bottom side is substantially square. This may make the holding element versatile with respect to possible orientations on the packaging unit, and/or provide a high ratio between retention capability and the space taken up by the holding element.
  • the width and the length of the bottom side of the holding element are 2 times the height of the holding element measured perpendicular to the bottom side or less. In one embodiment the width and the length of the bottom side are 1,5 times the height of the holding element or less. In one embodiment the width and the length of the bottom side are equal to or smaller than the height of the holding element.
  • the ratio between the longer of the length and width of the bottom side of the holding element and the length of the shortest side of inner bottom surface of the packaging unit is in the range from 1:3 to 1:20.
  • the height of the holding element measured from the bottom side in the height direction corresponds substantially to the distance between the inner bottom surface of the packaging unit and an opposite top section of the packaging unit forming a top surface, such as a lid.
  • a holding element may contribute to preventing sagging of the top section and/or deformation of packaging unit caused for example by other items being arranged on top of it.
  • the height of the holding element corresponds to the distance between the inner bottom surface of the packaging unit and an upper side of the highest component of the product in the packaged state. In that case the top section of the packaging unit may not be prevented from sagging or from being deformed, but the highest component will be protected from deformation caused by other items being arranged on top of the packaging unit.
  • the holding element(s) may for example be fastened to the packaging unit by means of a pressure sensitive, a non-hardening adhesive, or a holt-melt adhesive.
  • Mechanical fasteners, such as staples, may also be used.
  • the components of the product may be divided in two or more groups, each being retained by means of one or more holding elements, said groups for example comprising components to be used at different stages of the installation or use of the product.
  • flashing components for use at the top of a roof window may be arranged at one side of the packaging held by one or more holding elements
  • flashing components for use at the bottom of the roof window may be arranged at the other side of the packaging held by one or more other holding elements.
  • a holding element 1 for use in packaging a product comprising a plurality of components having different size and/or geometry in a packaging unit is shown.
  • the holding element 1 comprises a bottom section 10, a first side section 11, a second side section 12, a third side section 13, and a fourth side section 14, and is made from the paper-based blank shown in Fig. 2 .
  • the bottom section 10 defines a bottom side 101 of the holding element facing downwards in Fig. 1 and being configured for being attached to an inner bottom surface of a packaging unit as will described below.
  • the holding element 1 is made by folding along lines 110, 120, 130, 140, and the third and fourth side sections 13, 14 retain the first and second side sections 11, 12 by protrusions 111, 112, 121, 122 of the first and second side sections being inserted in slots 131, 132, 141, 142 in the third and fourth side sections.
  • the third and fourth side sections 13, 14 thus constitute locking sections retaining the holding element 1 in the folded state.
  • slots 1111, 1121, 1211, 1221 are also provided at the protrusions 111, 112, 121, 122 so that a slot at each protrusion may engage with each of the slots 131, 132, 141, 142 in the third and fourth side sections. This may ease the assembly of the holding element 1, but it is to be understood that one set of slots, either at the protrusions or in the third and fourth side sections 13, 14, may suffice.
  • the slots 131, 132, 141, 142, 1111, 1121, 1211, 1221 are all made with flaps 1110, 1120, 1210, 1220, 1310, 1320, 1410, 1420, which can be bent away from the slot during assembly of the holding element. This contributes to a firm fixation of the first and second side sections 11, 12, but it is also possible to use slots without such flaps at the protrusions and/or in the third and fourth side sections.
  • the slots 131, 132, 141, 142 shown in the third and fourth side sections have a trapezoidal shape at the sections where no flap is present. This is intended to facilitate insertion of the protrusions 111, 112, 121, 122 by providing a funnel-effect, but straight slots may also be employed.
  • the holding element 1 is made by folding entails that it can be supplied as a flat blank and folded only when needed, thus saving space during storage and transportation. This also applies to the other folded embodiments, which will be described below.
  • the holding element 1 in Fig. 1 defines four planes A, B, C, D being defined by the upper edges of the first and second side sections 11, 12, by the upper edges of the protrusions 111, 112, 121, 122 of first and second side sections, by the upper edges of the third and fourth side sections 13, 14, and by the lower edges of the protrusions 111, 112, 121, 122 of first and second side sections, respectively.
  • the references to upper and lower here indicate the positions relative to the bottom section 10 in a height direction H extending away from the bottom section perpendicular thereto.
  • each of the planes A, B, C, D is parallel with the bottom side 101 of the holding element, but if for example the protrusions 111, 121 of first and second side sections had different shapes or were provided at different heights, or if the first and second side sections were of a different height, planes A, B, and/or D could be inclined with respect to the bottom side.
  • plane C could be inclined by making the third and fourth sections with different heights or with inclined upper edges.
  • first and second side sections 11, 12 are non-parallel and converging in the height direction H. This provides strength and stability to the holding element 1, but the first and second side sections 11, 12 could also be parallel or diverging in the height direction H.
  • a width w of the bottom section 10 measured in a width direction W parallel to the folding lines 110, 120 delimiting the first side section 11 and the second side section 12 is 5% shorter than a length lb of the bottom section 10 measured in a length direction L in parallel to the folding lines 130, 140 delimiting the third side section 13 and the fourth side section 14, making the bottom side almost square.
  • the first side section 11 and the second side section 12 both have a length ls in the length direction L corresponding to the length of the bottom section, and due to the first and second side sections 11, 12 converging in the folded state shown in Fig. 1 , the height h of the holding element 1 is less than the length lb of the bottom section 10.
  • Is is approximately 1,4 times h.
  • Openings 123 in the first and second side sections 11, 12 may be used as a handle to facilitate handling of the holding element 1 or for engagement with a component of a product to be retained.
  • the openings are made by bent a section of material 1231 along folding line 1230 into the space delimited by the side sections 11, 12, 13, 14, but it is also possible to simply remove the section of material 1231.
  • Such openings are an optional feature and may be present also in other configurations of the holding element even though not explicitly described.
  • the holding element 1 may comprise only one opening and/or that the opening(s) may be located differently on the holding element.
  • FIG. 3 the holding element 1 shown in Fig. 1 is shown in use in a packaging, where a flashing assembly 3 for weather proofing two roof windows mounted side-by-side is arranged in a packaging unit 2, said flashing assembly being divided in two groups each being retained by two holding elements 1.
  • the packaging unit 2 is here a cardboard box of the three-sided hinge cover type and comprises a bottom section having an inner bottom surface 20 on which the flashing assembly rests, two shorter side sections 21, two longer side sections 22, and a lid section 23 hinged to one of the longer side sections.

  • the holding elements 1 are attached to the inner bottom surface 20 of a packaging unit 2 by the bottom side of bottom section 10 of each holding element being glued or adhered thereto, but other means of attachment and/or another number of holding element may also be employed.
  • a hot-melt or pressure sensitive adhesive is considered advantageous.
  • the holding elements are arranged so that the protrusions 111, 121 project over an edge 311 of the bottom flashing members 31 and abut on an inner side 321 of the top flashing members, thereby retaining the bottom flashing members in the height direction H and the top flashing members in the width direction W direction.
  • the total height of each holding element 1 is such that the position of the upper edges of the first sides sections 11, 12 corresponds substantially to the location of the component located highest in the packed state, here the side flashing member 33. This entails that in the closed state of the packaging unit 2 the holding elements will support the lid section 23, thereby reducing the risk of damage to the flashing assembly 3 in case a heavy item is arranged on top of the package.
  • the holding element 1 is symmetrical with identical protrusions and recesses on opposite sides means that it can be turned one way or the other and still engage the components of the product in the intended manner. It is, however, possible to make the first and second side sections 11, 12 with protrusions at different levels at the two sides. That would make the holding element even more versatile by allowing it to engage with even more different product components, but it would also require that the user arranging them in the packaging unit 2 has more skill and precision and it could potentially result in higher production costs.
  • Fig. 4 a second embodiment of the holding element 1 is shown.
  • the same reference numbers as in Figs 1-3 will be used for items having substantially the same function, even if they are not identical, and it is to be understood that features such as the opening 123 may apply to all embodiments even if not explicitly described.
  • the holding element 1 in Fig. 4 is made from a paper-based material, such as corrugated cardboard, by folding along lines 110, 120, 150 and comprises four sections, namely a bottom section 10, a first side section 11, a second side section 12, and a fifth side section 15.
  • the fifth side section overlaps the second side section 12 and is provided with tabs 153, which are bent into recesses in the second side section, thus serving as locking sections retaining the holding element 1 in the folded state.
  • the bottom section 10 rests on the inner bottom surface 20 of a packaging unit and engages a bottom flashing member 31 and a top flashing member 32 as described above with reference to Fig. 3 .
  • the total height of the holding element 1 corresponds to the height of the top flashing member 32, and protrusions 122 of the first and second side sections 11, 12 engage the inner side 321 of the top flashing member.
  • the first side section 11 has a protrusion corresponding to the one marked 112 in Fig. 2 , and that it is located at the same height as the protrusion 122, just as is seen for protrusions 111, 121 in Fig. 3 .
  • the position of the protrusions 112, 122 allow them to project underneath a bent edge 322 of the top flashing member thereby allowing a tight contact with the top flashing member.
  • Upper edges 114, 124 at recesses in the first and second side sections 11, 12 serve the same purpose as the upper edges of the third and fourth side sections of the holding element in Fig. 1 , so that this embodiment too provides four planes.
  • these upper edges 114, 124 projects under and supports an edge 311 of the bottom flashing member 31.
  • the first and second side sections 11, 12 are converging in substantially the same way as in the embodiment in Fig. 1 , but the first side section 11 is here perpendicular to the bottom section 10 and the second side section is inclined so that the holding element 1 has the overall shape of a right-angled triangle.
  • This holding element 1 could also be used in a different orientation, where the longer section here forming the first side section 11 was attached to the inner bottom surface 20 of the packaging unit, thus serving as the bottom section.
  • the result would be a lower and wider holding element with protrusions located at different heights above the inner bottom surface 20 of the packaging unit.
  • FIG. 5 A third and somewhat simpler embodiment of the holding element 1 is shown in Fig. 5 .
  • This embodiment comprises only a bottom section 10 and a first side section 11, which are perpendicular to each other in the folded state.
  • the bottom section 10 and the first side section 11 are identical, meaning that the bottom section may also serve as the first side section and vice versa by turning the holding element.
  • recesses and protrusions are provided only at one end in the width direction W, but there could also be recesses and protrusions at the other end, either identical to those shown or different to allow different uses.
  • Fig. 5 the holding element 1 is shown inserted into a groove formed by the bent edge 322 of the top flashing member 32. This provides a good contact with the top flashing member 32, which may at least partially compensate for the reduced structural stability of this holding element 1 compared to those in Fig 1-4 .
  • the material used for the embodiments shown in Figs 1-5 may for example be corrugated cardboard or paperboard.
  • FIG. 6 A fourth embodiment of the holding element 1 is shown in Fig. 6 .
  • This holding element is made by stacking four layers 16, 17, 18, 19 of honeycomb cardboard, each layer having different dimensions such that protrusions and recesses are formed, and each layer being provided with a paper cover facilitating interconnection and attachment to the inner bottom surface 20 of the packaging unit.
  • the free upper surface 161 of the lowermost layer 16 seen in the height direction H serves substantially the same function as the upper edges of the third and fourth side sections 13, 14 in Fig. 1 and the upper edges 114, 124 in Fig. 4 , i.e. projecting under and/or supporting the edge 311 of the bottom flashing member 31.
  • the protrusions formed by the third layer 18 serve the same function as the protrusions 111, 112, 121, 122 of first and second side sections 11, 12 in Figs 1-5 , engaging the inner side 321 of the top flashing member 32, and the free upper surface 181 projects underneath the bent edge 322.
  • the holding element 1 in Fig. 6 is considerably more stable than those shown in Figs 1-5 , particularly when it comes to pressure applied in the height direction, for example caused by another item being arranged on top of the packaging, as the relatively large top surface 191 will serve to distribute loads. On the negative side, this holding element 1 takes up more space and may be more expensive to manufacture.
  • one or more of the layers 16, 17, 18, 19 may be made wholly or partially from several layers of corrugated cardboard of identical dimensions stacked on top of each other and interconnected. The layers of corrugated cardboard may extend either in parallel to the bottom side 160 or in the height direction.
  • holding elements 1 has been described above as relating to the retainment of a bottom flashing member 31 and a top flashing member 32 it is to be understood that these are just examples of components of a product.
  • Other examples are other flashing components, such as side flashing members, insulating members for use around a window in an installed state, and window accessories, such as shutters, shades, blinds, and curtains.
