Title of Invention

A holding element for use in packaging a product, a packaging, a method for making a holding element, and a method før packaging a product

Technical Field

The present invention relates to a holding element for use in packaging a product comprising a plurality of components having different size andior geometry in a packaging unit, where a bottom side of the holding slemert 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 af the product, and where the holding slement comprises protrusions, recesses and/or siots extending in one or more planes, which is/are paralis! with the bottom side of the holding element, wherein the holding element is made from a paper-based material by folding, wherein the holding 18 slement is made by folding and comprising a bottom section, a first side section, and a second side section, said bottom section forming the bottom side of the holding element, sald first and second side sections being non-parallel and converging in a height direction extending away from the bottom section perpendicular thereto. The invention further relates to a packaging including such a holding element, to a method for making a holding element, and lo a method for packaging a product using such a holding element.

Background Art

Such a holding element is known from EFT710163A1, where blocks, 28 made preferably from expanded polystyrene (EPS), are used for keeping components of a flashing assembly for a roof window in thelr intended positions within the packaging unit 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. As 20 components of a flashing assembly will be at least parlially visible in the installed state of the roof window product, it is important that they are not scratched or deformed. And even møre imporiantly, a deformation is to be avoided as it may influence negatively on the weather proofing function of the

DK 181395 B1 2 flashing or covering components. By preventing the components rom moving too much around in the packaging unit, which is typically a cardboard box, the risk of them being jammed bebveen other component is reduced, and so is the possibility for contact with other components, which might result in scratches. & Another example is disclosed in IJP3011001078A.

While the holding elements described in EP1710163A1 have worked well from a product protection point of view, the blocks cannot easily be re-used and are rarely recycled, which has given rise to environmental cConcems.

Summary of Invention

With this background, it is an object of the vention to provide an aliernative holding element having a reduce climate footorint and a packing including such a holding slement

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. in a first aspect of the invention at least one object is achieved with a holding slement of the kind mentioned in the introduction which is furthermore characterized in that the holding element further comprises a third side section constituting a locking section retaining the first and second side sections. in a second aspect of the invention al least one object is achieved with a method for making a holding element, where a paper-based material is folded £5 and/or stacked thereby forming a bottom side and protrusions, recesses andfor 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 botlom 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 it, a fhree-dimensional shape suitable of serving as a holding slement can be achisved with a minimal material

DK 181395 B1 3 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.

While corrugated cardboard or honeycomb cardboard contains a small about of adhesive, which will typically contain one or more polymers, the {otal amount of polymers used will be considerable reduced compared to the prior art blocks of EPS. This may in itself reduce the climate footorint, but it may also mean that 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 slements actually being recycled instead of just being disposed of as combustible waste.

Another potential advantage of using a paper-based material is that it may be biologically degradable. Light-weight packaging tems, such as EPS, are easily caught by wind when installing a roof window product on a roof of building and may end up in nalure or other places where ft 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-hased material does litle harm. i is to be understood that while 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 he used, including combinations of differant types of fibres. in Europe, up to 5% of other materials, such as adhesives, is acceptable in recycling, but a maximum of 3% is recommended.

A further advantage applying to the holding element made by folding je that if 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 prior fo reuse of recycling may also provide advantages with respect to space.

A third aspect of the invention relates to a packaging for use in

DK 181395 B1 4 packaging a product comprising a plurality of components having different size and/or geometry, which packaging comprises a packaging unit and al leas ons holding element as described above, sald holding element being formed separately from said packaging unit and atfached 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 rstained from movement relative to the packaging unit in two directions being perpendicular to sach other,

A fourth aspect of the invention relates ta a method for packaging a 10 product comprising a plurality of components having different size and/or geometry in a packaging unit, comprising:

Providing a packaging unit, such as 8 cardboard box or a dank for a cardboard box,

Forming at least one holding element separately from said packaging 18 unit by folding a paper-based material as described above,

Arranging the holding slement{s) on the inner baltom surface of the packaging unit such that the holding element is in contact with at least one of said components, the holding element being arranged in dependence of the geometry of the components for separation thereof in such a way that at least 20 one of the components is retained from movement relative to the packaging unit in two directions being perpendicular to each other, and

Fastening the holding stlementis) to the inner bottom surface of the packaging unit (hy adhesion).

Using one or more holding elements of the type described above in packaging a product comprising a plurality of components having different size andfor geametry and arranging ivthem 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 matenal consumption and hence a comparatively small climate foot print. Furthermore, the holding element may be recycled together with a packaging unit if the packaging is also made from a paper-hased material as is very often the case. Providing the holding element separately rather than forming part of the packaging unit and subsequently

DK 181395 B1 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 & polentially 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 fo 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 elements) in the following, a description common to alf aspects of the invention will be given, and it is to be understood that features described with reference to one aspect also applies to the others unless otherwise stated. 18 in one embodiment, where the holding element is made by folding, i comprises a locking section or locking element retaining the holding element in the folded state. Examples of locking elements are dots or lines of adhesive or mechanical fasteners, such as staples, snap-locking fasteners or hook-and- iook type fasteners, such as Velcro®. Examples of locking sections are a flap folded into a recess in the holding element, an edge of the paper-based material fitling into a slot in the holding element, pairs of slot engaging with each other, and hook-shaped recesses or aps engaging with each other. in one embodiment, where the holding element is made by folding, i comprises a bottom section, a first side section, a second side section, and a third side section, said bottom section forming the boltom side of the holding element, sad first and second side sections being non-parallel and converging in a height direction extending away from the bolfom section perpendicular thereto, and said third side section constiluting 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 muiust distance decreases with increasing distance from bottom section, possibly giving the holding element a triangular or tapezoldal shape when seen from the side in

DK 181395 B1 8 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 fram the bottom section. in that case, the holding slement will have the overall shape of the letter A when seen fram the side in paraliel fo the bottom section and fo the first and second side sections. This holding element is preferably made from corrugated cardboard. in one embodiment the holding element is made from two or more lavers of corrugated cardboard and/or honayocomb cardboard each having two major surfaces and one or more minor surfaces exiending between them, said 18 layers being stacked and interconnected with one or both of the major surfaces of each layer facing a major surface of anofher layer and with the major surfaces of all layers extending subsiantially in parallel. One layer defines the bottom side of the holding element and other layers may be made with different size or shape so thal recesses or profrusions are formed on the holding 28 element in a holding element made from two or more ayers, which have been stacked and interconnected, a slot may be formed between two layers by the ayers being left unconnected at a seclion of their respective major surfaces.

Such 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 relained.

To make the holding element as versatile as possible, mutually opposite sides of the holding element extending away from the bottom side may he provided with identical protrusions, recesses and/or sols. This may for example allow identical holding slements to be used al both ends of an elongate product component without having to turn one of them. It may, however, also be advantageous thal the mutually opposite sides of the holding

DK 181395 B1 7 glement are provided with different protrusions, recesses and/or slots so that the same holding element may be used for different purposes by arranging tin different orientations. in one embodiment, the holding element is provided with a plurality of recesses, siols 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 bottam surface of the packaging unl.

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. in one embodiment, the bottom side is substantiallv square.

This may make the holding element versatile with respect to possible orientations on the 18 packaging unit, and/or provide a high ratio between retention capability and the space laken up by the holding element. it is presently considered advantageous that the ratio between the jonger of the length and width of the bottom side and the length of the shorter side of inner bottom surface of the packaging unit is in the range from 13 fo 120. in one embodiment the height of the holding element measured from the botfom 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 lop surface, such as a id.

Such a holding element may contribute ta preventing sagging of the top section and/or deformation of packaging unit caused for example by other tems being arranged on top of i in another embodiment the height of the holding element corresponds fo the distance behveen 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 dems being arranged on top of the

DK 181395 B1 8 packaging unit.

The holding element{s} may for example be fastened fo the packaging unit by means of a pressure sensitive, non-hardening adhesive or a holt-melt adhesive. a The components of the product may be divided in hvo or more groups, each being retained by means of one or more holding elements, said groups for example comprising components ta be used at different stages of the installation or use of the product. Ås an example, 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, and 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.

The packaging unit may for example be made from a workpiece of pasteboard or corrugated cardboard that is folded into a box or a carton. This 18 maybe done either before or after arranging the holding element{s} on the inner bottom surface of the packaging unit.

Description of Embodiments a Referring initially to Fig. 1, a holding slement 1 for use in packaging a product comprising a plurality of components having different size andfør 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 fo sn inner botlom surface of a packaging unit as will described below.

The holding element 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 18 sections 11, 12 by protrusions 111, 112, 121, 122 of first and second side sections being inserted in slots 13%, 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. in this embodiment slots 1111, 1131, 1211, 1221 are also provided at the protrusions 111, 112, 121, 122 so that a slot al 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 af the protrusions or in the third and fourth side sections 13, 14, may suffice. 35 in this embodiment the slots 131, 1323, 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 af the holding element.

This contribules to a firm fixation of the first and second side sections 11, 12, but I is also possible to use stats without such flaps at the protrusions andlor in the third and fourth side sections.

The slots 131, 132, 141, 142 shown in the third and fourth side sections have a frapezoidal shape at the sections where no flap is present. This

DK 181395 B1 +10 i= intended to facilitate insertion of the protrusions 111, 1128, 121, 122 by providing a funnel-effect, but straight slots may also be employed.

The fact that the holding element 1 is made from folding entails that i can be supplied as a fat blank and folded only when needed, this saving space & during storage and transportation. This also applies fo 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, 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 profrusions 111, 121, 122 of frat 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. in this smbodiment, sach of the 18 planes A, B, C, D is parallel with the bottom side 101 of the holding stement, but if the protrusions 111, 121 of first and second side sections had different shapes or were provided at different hefghis 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. Likewise, plane C could de inclined by making the third and fourth sections with different heights or with inclined upper edges. in the embodiment shown in Fig. 1, the first and second side sections 11, 12 are non-parallel and converging in the height direction H. This provides strength and stability fo the holding element 1, but the first and second side sections 11, 12 could also be parallel or diverging in the height direction H. 28 Cpenings 123 in the first and second side sections 11, 12 may be used as a handle to facilitate handling of the holding slement 1 or for engagement with a component of a product io be relained. In this embodiment the openings are made by bent a section of maternal 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. Likewise, it is to be understood thal the

DK 181395 B1 +11 holding element 1 may comprise only one opening and/or that the openingis) may be located differently on the holding siement.

Turning now to Fig. 3 the holding element 1 shown in Fig. 1 is shown in use in a packaging, where a flashing assembly 3 for a roof window is & arranged in a packaging unit 2, said flashing assembly being divided in wo groups each being retained by two holding elements.

The packaging unit 2 here comprises a bottom section having an inner bottom surface 20 on which the fashing assembly rests, two shorter side sections 21, two longer side sections 22, and a lid section 23 hinged to one of 10 the longer side sections. Other types of a packaging units, including boxes of the shoe box type, may, however, also be used.

The flashing assembly here comprises a plurality of components having different size and geometry, including hwo bottom flashing members 31, two top flashing members 32, and side flashing members 33 for weather 18 proofing bwo roof windows mounted side-by-side, The holding element may, however, also be used in packaging other products. in this embodiment, 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 thersto, but other means of 20 attachment and/or another number of holding element may also be emploved.

At present the use 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 a transverse direction. The total height of each holding element 1 corresponds substantially fo the location of the component located highest in the packed state, here the side flashing member 33. This entails that in the dosed 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 tem is arranged on top of the package.

DK 181395 B1 12

The fact that the holding slement 1 is symmetrical with identical protrusions and recesses on both sides means that # 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 af the hvo 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 precizion and it could potentially result in higher production costs.

Turning now fo Fig. 4, a second embodiment of the holding slement 1 is shown. Here as well as in the remaining figures, the same reference numbers as in Figs 1-3 will be used for Hems having substantially the same function, even hey are not identical, and it is to be understood that features such as the opening 123 may apply fo all embodiments even if not explicitly described. 18 The holding slement 1 in Fig. 4 is made from a paper-based material, such as corrugated cardboard, by folding slong lines 110, 120, 180 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 ovenaps 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. ff would, however, also be possible to interconnect the second and fifth side sections using an adhesive or separate focking slements, such as slaples. Al present it is considered advantageous to use locking sections as the paper-based material is thus kept free of other materials, which will facilitate regycling.

The bottom section 10 resis on the inner bottom sisface 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 132 of first and second side sections engages the inner side 321 of the top flashing member. As will be seen the position of the protrusion 122 allows It fo project underneath a bent

DK 181395 B1 13 edge 322 of the top flashing member thereby allowing a tight contact with the top flashing member.

Upper edges 114, 124 al 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.

While the first and second side sections 11, 12 are converging in the embodiment in Fig. 1, the first side section 11 is here perpendicular to the botfom section 10 and the second side section is inclined so that the holding slement 1 has the overaft shape of a right-angled tnangle.

This holding element could also be used in a different onentation, where the longer section here forming the first side section 11 was attached fo the inner bottom surface 20 of the packaging unit, thus serving as the bottom section. The result would be a lower and wider holding slemant with protrusions 18 located at different heights above the inner bottom swiace 20 of the packaging unit.

A third and somewhat simpler embodiment of the holding element 1 is sown 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 bottom section may also serve as the first side section and vice versa by fuming the holding element. in the embodiment shown recesses and protrusions are provided only at one end, but there could also be recesses and protrusions at the other end, either identical to those shown or different fo allow different uses. in Fig. 5 the holding element 1 is shown inserted into the groove formed by the Dent edge 322 af the top flashing member 32. This provides a good contact with the top flashing member 32, which may at least parlially compensate for the reduced structural stability of this holding element 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.

A fourth embodiment of the holding element 1 is shown in Fig. &. This

DK 181395 B1 14 holding element is made by stacking four layers 18, 17, 18, 19 of honeycomb cardboard, each layer having different dimensions such that protrusions and recesses are formed and each being provided with a paper cover laver faciliiating interconnection and attachment fo the inner bottom strface 20 of the & packaging unit.

The free upper surface 161 of the lowermost layer 18 seen in the height direction H serves 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, ie. projecting under and/or supporting the edge 311 ofthe botlom flashing member 31. Likewise, the protrusions formed by the third laver 18 serve the same function as the protrusions 111, 112, 121, 122 of first and second side sections 11, 12 in Figs 1-3 engaging the inner side 321 of the top flashing member 32, and the free upper surface 181 projects underneath the bent edge 322. It would also be possible © leave out the second layer 17 and interconnect the first and 18 fhird layers 16, 18 only partially, leaving a siot between them, which could be used for receiving the edge 311 of the bottom Hashing members 31. This would require a higher degree of precision in arranging the holding element 1, but would in turn provide a very reliable retainment of the bottom flashing member 31.

The holding element 1 in Fig, © is considerably møre stadle than those shown in Figs 1-5, particularly when it comes fo pressure applied in the height direction, for example caused by another ftem being arranged on top of the packaging, as the relatively large top surface 191 will serve fo distribute loads.

On the negative side, this holding element 1 takes up more space and may be more expensive to manufacture. To reduce cost, one or more of the layers 18, 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 paraftel to the bottom side 180 or in the height direction,

Even though the use of the 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 fo be understood that these are just examples of

DK 181395 B1 18 components of a product. Other examples are other flashing components, such as side fashing members, insulating members for use around a window in an installed state, and window accessaries, such as shutters, shades, blinds, and curtains. a
