Description

Technical Field

[0001] This utility model relates to a packaging insert for protecting the corner portion of a packaged roof window, wherein the packaging insert is made of folded cardboard and includes a base segment having a length direction and a height direction extending perpendicular to the length direction, wherein the base segment includes two longitudinal edges extending along the length direction and two end edges extending between the longitudinal edges, wherein the base segment includes a fold line extending along the height direction and separating a first portion and a second portion of the packaging insert, wherein the first portion and the second portion extend substantially perpendicular to each other in the folded use state of the packaging insert, and wherein each of a first protrusion on the first portion and a second protrusion on the second portion protrudes from the base segment in a width direction extending perpendicular to both the length and height directions. This utility model also relates to a packaged roof window. Background Technology

[0002] When storing and transporting roof windows before installation in the roof structure, it is important to ensure that the roof windows are not damaged. Therefore, most roof windows are individually packaged in cardboard boxes, and shock-absorbing packing inserts are placed along the outer side of the roof window frame and at the corners of the frame between the roof window and the cardboard box to provide cushioning in the event of the packaged roof window being dropped or handled roughly. "Outer side" should be understood here as the smaller side facing away from the opening covered by the roof window panes, while the larger side extending parallel to the panes will be referred to as the "inner side" and "outer side," corresponding to the sides intended to face the interior and exterior of the building, respectively, when the roof window is installed.

[0003] Shock-absorbing packaging inserts have traditionally been made of expanded polystyrene (EPS), which is inexpensive and has excellent shock-absorbing properties. However, in recent years, there has been a desire to reduce the amount of polymer used in packaging for environmental reasons.

[0004] For example, paper-based shock-absorbing packing inserts of the type mentioned in the introduction of US4000843 have thus gained new popularity, but paper-based packing inserts that are expected to better protect roof windows are also desired. Utility Model Content

[0005] Against this backdrop, the purpose of this invention is to provide a packaging insert for protecting the corner of a packaged roof window, thereby reducing the risk of damage to the roof window during storage and transportation.

[0006] In a first aspect of the present invention, this and other objectives are achieved by a packaging insert as mentioned in the introduction, characterized in that a first protrusion and a second protrusion are positioned continuously relative to each other in the length direction and positioned at a certain distance from each longitudinal edge of the base segment, the first protrusion including a protrusion engagement element, and the second protrusion including a protrusion engagement element.

[0007] In a second aspect of this invention, the above and other objectives are achieved by a packaged roof window comprising a roof window arranged in a cardboard box and at least one package insert as defined above, wherein the cardboard box comprises two main sides extending along an inner side and an outer side of the roof window and four secondary sides extending between the main sides, wherein a first portion of the package insert is arranged between a first frame member of the roof window and a secondary side of the cardboard box, and wherein a second portion of the package insert is arranged between a second frame member of the roof window and a secondary side of the cardboard box.

[0008] Methods for cladding roof windows may include:

[0009] Cardboard boxes are provided.

[0010] Arrange the roof windows in cardboard boxes.

[0011] Provide multiple packaging inserts as specified above.

[0012] Fold each package insert along the fold line such that the first portion extends perpendicular to the second portion, and such that the first protruding engagement element engages with the second protruding engagement element, and

[0013] Arrange the folded packaging inserts at the corner of the roof window.

[0014] Below, a general description of the present invention will be given, and it should be understood that although some embodiments may be described as relating primarily to one aspect of the present invention, they will also apply to other aspects unless otherwise stated.

[0015] By positioning the first and second protrusions at a distance from each longitudinal edge of the base section, the first and second protrusions will be positioned between the outer side of the roof window and the secondary side of the cardboard box in the packaged state, thus maintaining a distance between the roof window and the cardboard box. Therefore, the protrusions create a gap between the roof window and the cardboard box, which will provide cushioning in the event of the packaged roof window falling or being handled roughly. The use of protrusions allows for adaptation to the shape of the outer side of the roof window, compared to packaging inserts of the type known from US4000843, where cushioning is provided by a closed compartment with a rectangular cross-section within the package. The protrusions can be positioned such that they project above, below, or between the protrusions of the roof window. As an example, the protrusions can project below the covering member on the outer side of the roof window frame, i.e., the side intended to face outwards in the installed state of the roof window. This, in turn, will allow loads on the roof window generated by the transfer of forces between the roof window and the protrusions to affect the strongest part of the roof window. Typically, the protrusions will be positioned such that they contact the frame of the roof window.

[0016] By positioning the first and second protrusions at a certain distance from each longitudinal edge of the base segment, the risk of the first and / or second protrusions being pressed to the side and into the space between the roof window and the main side of the cardboard box is significantly reduced. Therefore, the protrusions remain in contact with the outer side of the roof window, providing some protection even if they deform.

[0017] The packaging insert is held in use by mechanically or frictionally engaging the first and second protruding engagement elements, thereby giving the packaging insert an angled shape suitable for surrounding and protecting the corner of a roof window. Mechanical engagement should be understood as an engagement in which one protruding engagement element physically impedes the movement of the other protruding engagement element, while friction engagement should be understood as an engagement in which the two protruding engagement elements press against each other. These two types of engagement can be combined such that friction engagement impedes the movement necessary to break or open the mechanical engagement between the two protruding engagement elements.

[0018] The engagement between the protruding engagement elements results in an overlap of materials between the first and second protrusions. When using packaging inserts in which the first and second portions abut each other at only a 45-degree angle, such as those known from US4000843, experience shows that roof windows tend to press themselves between the two portions, leaving only the base section and the cardboard box to protect the roof window. The overlap established by the engagement between the first and second protruding engagement elements hinders this movement of the roof window.

[0019] At least one of the first protrusion engagement element and the second protrusion engagement element may be hook-shaped and / or the first protrusion engagement element and the second protrusion engagement element may be substantially the same, possibly mirror-reversed.

[0020] At least one of the first and second protrusions can be elongated, wherein its longest dimension extends along the length of the base segment to provide a longer / larger area in contact with the roof window than when using a more localized protrusion. It is currently considered advantageous that each of the elongated protrusions has a length along the length direction of at least 15 cm, preferably at least 20 cm, which is measured in use at the point where the protrusion contacts the roof window.

[0021] The first and second protrusions do not need to contact the roof window in its packaged state, but this is usually the case. If the packaged roof window is arranged such that it rests on one of the secondary sides of the cardboard box, the roof window will be pressed against the portion of the packaging insert extending along that secondary side under the influence of gravity. In this case, only the protrusions on that portion / these portions can contact the roof window. However, packaging inserts that are slightly oversized can also be used, such that they are wedged between the secondary side of the cardboard box and the outer side of the roof window. In this case, the packaging inserts located on the opposite side of the roof window can always remain in contact with the roof window compared to the side on which the packaged roof window rests.

[0022] The protrusions can be retractable, for example, by being hollow, thus allowing the protrusions to yield under pressure. This allows the protrusions to collapse in the event of an overhanging roof window being exposed to excessive forces, such as by falling. One or more protrusions can then absorb at least some of the impact force, thereby protecting the roof window.

[0023] In one embodiment, at least one of the first and second portions includes two protrusions at different levels in the height direction. If the two protrusions are disposed on both the first and second portions and at the same level, both protrusions may be provided with protrusion engaging elements to provide two sets of overlapping and engaging protrusions. It is also possible to have three or more protrusions at different levels in the height direction.

[0024] Different levels can be determined by the design of the roof window or by mechanical considerations to achieve the best possible damping characteristics, and protrusions at different levels can have different sizes and / or shapes to allow the package inserts to match the shape of the roof window.

[0025] In one embodiment, the protrusions are arranged symmetrically about the length direction, such that they are located at the same distance from the longitudinal edge. This means that it does not matter which side of the package insert is up or down in the packaged state, thus eliminating the risk of the package insert being placed in the wrong position, which can achieve suboptimal protection for the roof window. If there is only one protrusion on each section, a similar effect can be achieved by having each protrusion located at the center of the base section when viewed along the height direction and preferably having a symmetrical cross-sectional shape.

[0026] Additionally or alternatively, the first and second parts may have the same length, such that the same length of the outer side of the roof window is covered regardless of how the packing inserts are arranged.

[0027] It is currently considered advantageous that the length of each of the first and second parts along the longitudinal direction is at least 15 cm, preferably at least 20 cm. The optimal length may depend on the size of the roof window. It is currently considered advantageous that at least 30% of the length / width of the roof window is covered by the packing insert, and for larger roof windows, the packing insert surrounding the corner of the roof window as described above can be used in combination with other linear packing inserts. Such linear packing inserts can be made, for example, from honeycomb cardboard or multi-layer corrugated cardboard.

[0028] In one implementation, the height of the base section along the height direction corresponds to the internal dimensions of the cardboard box. This allows the base section to reinforce the secondary sides of the cardboard box, thereby giving the cardboard box better compressive strength, which is advantageous when packing roof windows are stacked on top of each other.

[0029] In one embodiment, the protrusion is made of folded cardboard, and the protrusion can be made from the same cardboard sheet, or even from the same cardboard sheet as the base segment, so that the packaging insert can be made from a single cardboard sheet. This can be achieved by folding the cardboard sheet such that one segment of the sheet forms the base segment and the protrusion is formed on another segment. However, it is also possible to simply fold the protrusion on the segment forming the base segment and then stabilize these folded protrusions, for example, by applying adhesive tape across the concave sides of the folded protrusions. Manufacturing the packaging insert from a single cardboard sheet can facilitate production and / or reduce costs.

[0030] Manufacturing one or more protrusions from individual sheets of cardboard allows for the use of different cardboard materials, such as corrugated cardboard for the protrusions and multi-layer corrugated cardboard for the base section, thereby giving one or more protrusions different characteristics.

[0031] Alternatively, the protruding and base sections can be folded from a cardboard sheet and then attached to another material sheet to achieve a stronger base section. This can, for example, help reinforce the sides of a cardboard box as described above. The other material sheet can be cardboard, but it can also be, for example, a paper-based honeycomb material or a wood-based material.

[0032] If each protrusion is made of cardboard by folding, each protrusion will typically have two legs extending from the base segment toward converging with each other, thus giving the protrusion a trapezoidal or triangular cross-sectional shape.

[0033] In embodiments where two protrusions on the same portion of the packaging insert have converging sides, the distance between the two protrusions in the height direction at the base section can be less than 5 mm, preferably less than 1 mm. In this way, the protrusions can support each other at the base section, thereby preventing the protrusions from collapsing. Ideally, for this purpose, the distance between the two protrusions would be zero, but this would be impossible in practice, especially when the two protrusions are made of a folded cardboard sheet.

[0034] In embodiments where the entire packaging insert is made from a single sheet of cardboard—where one segment of the sheet forms the base segment and the protrusions are formed on another segment—the two edges of the sheet can be located at one of the longitudinal edges of the packaging insert. This eliminates creases and avoids joints on the surface of the packaging insert that could potentially affect its strength and / or stiffness. However, if the packaging insert includes two or more protrusions on each section, joints can be located between the protrusions, whereby the joints can help stabilize the protrusions, particularly when adhesive is used at the joints. It has been assumed here that the cardboard sheet is folded along a fold line extending parallel to the length direction; however, it should be noted that the invention is not limited to such embodiments.

[0035] Regardless of whether the protrusions are made of folded cardboard sheets or different materials such as honeycomb paperboard or multilayer paperboard, they can be attached to the base section using an adhesive such as hot melt adhesive. Alternatively or additionally, nails or other mechanical devices for attachment can be used. If one or more protrusions form part of a sheet of material, the sheet can be attached to the base section in a similar manner. If the entire packaging insert is made of a single cardboard sheet, where one section of the sheet forms the base section and the protrusions are formed on another section, the two sections can be connected to each other in a similar manner.

[0036] In embodiments where one segment of the sheet forms the base segment and the protrusion is formed on another segment, the other segment itself may include two or more sub-segments. As an example, the protrusion of a first portion of the packaging insert may be formed on a first sub-segment, and the protrusion of a second portion of the packaging insert may be formed on a second sub-segment, the sub-segments being completely separate from each other but connected to the base segment. This separation of the first and second sub-segments will generally extend along the fold line, resulting in less rigidity of the packaging insert at the fold line and thus potentially facilitating folding. Similar folding-facilitating separation can also be found in embodiments where the protrusion is formed on a cardboard sheet separate from the base segment.

[0037] The above description of the packaging insert and its use refers only to an embodiment in which the first portion extends along the first frame member of the roof window and the second portion extends along the second frame member of the roof window, i.e., where the packaging insert surrounds the corner of the roof window. However, the packaging insert can also be used in an unfolded state in which the packaging insert is not folded along the fold line. In this unfolded state, the base section is linear, and the first protrusion and the first protrusion engaging element and the second protrusion engaging element do not engage with each other. The unfolded packaging insert will generally be arranged on the outer side of the roof window, for example, between two folded packaging inserts each arranged at the corner of the roof window, but the unfolded packaging insert can also be arranged on the window pane of the roof window to protect it from impact or to keep the main side of the cardboard box a certain distance from the window pane, for example, to prevent wear and tear.

[0056] First refer to Figure 1The illustration shows a packaging insert 1 in its unfolded state for protecting the corner of a packaged roof window. The packaging insert is made of folded corrugated cardboard and includes a base segment 10 and two sets of protrusions 11 and 12. Each set of protrusions includes first protrusions 111 and 121 protruding from the first segment 101 of the base segment and second protrusions 112 and 122 protruding from the second segment 102 of the base segment. The protrusions extend in a width direction W perpendicular to the length direction L and height direction H of the base segment 10.

[0057] exist Figure 2 In the folded state shown, the packaging insert 1 has been folded along the fold line F, which extends along the height direction H and separates the first part A of the packaging insert from the second part B of the packaging insert. Figure 2 In the folded use state of the package insert shown, the first part A and the second part B extend substantially perpendicular to each other, thereby allowing the first part A and the second part B to surround the corner of the packaged roof window, as will be shown later.

[0058] The first protrusions 111, 121 and the second protrusions 112, 122 of each group are positioned continuously in the length direction L and are located at a certain distance from each longitudinal edge 103 of the base segment 10. In this embodiment, the protrusions are elongated, wherein the longest dimension of the protrusion extends along the length direction L and extends to the end edge 104 of the base segment 10, but this may not be the case in other embodiments.

[0059] exist Figure 1 and Figure 2 In the embodiment described, the two sets of protrusions 11 and 12 are identical except for being mirror images, and are arranged symmetrically about the length direction L, such that they are located at the same distance from the corresponding longitudinal edge 103. This means that regardless of how the packaging insert is... Figure 2 Whether the arrangement is shown in the ground or inverted, the packaging inserts appear identical. This means that the risk of the packaging inserts being incorrectly positioned during use is low.

[0060] As in Figure 1 As best observed, each of the first protrusions 111, 121 and each of the second protrusions 112, 122 includes a protrusion engagement element 13. These protrusion engagement elements are configured to engage with each other and lock the protrusions together once the packaging insert has been folded along the fold line F, thereby securing the packaging insert in place. Figure 2 The state shown in the image.

[0061] exist Figures 3a to 3gThe shape and function of the protruding engagement element 13 are shown in more detail in the schematic diagram, wherein... Figure 1 The protrusion engagement element shown as located on the first protrusion 121 of the second group 12 and the second protrusion 112 of the first group 11 is designated as 13a, and in Figure 1 The protrusion engagement element shown in the diagram, located on the first protrusion 111 of the first group 11 and the second protrusion 122 of the second group 12, is designated as 13b.

[0062] When the base segment 10 extends along the line extending to Figures 3a to 3g When the fold line F in the drawing plane folds, the two protruding joining elements 13a and 13b rotate relative to each other. Figures 3a to 3g This is illustrated by the rotation of the second protruding engagement element 13b, while the protruding engagement element 13a is shown to remain stationary, as can be seen by comparison. Figure 3a and Figure 3b What can be seen.

[0063] As the folding and thus mutual rotation progress, the tip segment 131 of the second protruding engagement element 13b enters below the first protruding engagement element 13a, as... Figure 3c As shown, and the segments 132 and 133 of the first protruding engagement element 13a enter below the second protruding engagement element 13b, as... Figure 3d and Figure 3e As indicated in the document.

[0064] When a 90-degree fold has been achieved, the two triangular recesses 134 and 135 in the two protruding engagement elements 13a and 13b engage with each other, as shown by comparison. Figure 3f and Figure 3g As can be seen, this locks the two protruding engagement elements together. Furthermore, the tip segment 131 of the protruding engagement element 13b and the end surface 136 of the protruding engagement element 13a engage with the base segment 10, thereby preventing further folding of the packaging insert.

[0065] In addition to the mechanical locking of the two protrusion joining elements 13a and 13b to each other by the engagement of the two recesses 134 and 135, the segments 131, 132, and 133 that have been inserted below the other segments of the protrusion will press against the inner side of these other segments due to the elasticity of the cardboard material, thereby generating friction, which will also hinder the unfolding of the packaging insert.

[0066] exist Figure 2In the illustrated embodiment, the protrusion engagement element on the first protrusion 111 of the first group 11 is the same as the protrusion engagement element on the second protrusion 122 of the second group 12, and the protrusion engagement element on the second protrusion 112 of the first group is the same as the protrusion engagement element on the first protrusion 121 of the second group. This requires that the packaging insert be truly symmetrical, such that it does not matter which side of the packaging insert is up or down when in use.

[0067] Figure 4 Another embodiment of the packaging insert in its unfolded state is shown. In this figure and in the following figures, features having substantially the same function are used even though they are structurally different. Figures 1 to 3g The same reference numerals will be used in the accompanying drawings. Only the differences between embodiments will be described. It should be understood that other features and functions are the same as those described with reference to the previous drawings.

[0068] As in Figure 1 and Figure 2 Similarly, the two sets of protrusions 11, 12 are formed by folding along a fold line extending parallel to the length direction L, and each protrusion has two legs 14a, 14b extending away from the base segment 10 and converging towards each other, thus giving the protrusion a triangular cross-sectional shape. However, Figure 1 and Figure 2 The protrusions in the middle have a right-angled triangular cross-sectional shape and are arranged such that they are spaced apart from each other by a distance D in the height direction H, while Figure 4 The protrusions in the middle have an isosceles triangular cross-sectional shape and abut against each other at the base segment 10, that is, with a distance of less than 1 mm.

[0069] It has been discovered that Figure 4 Compared to the implementation method in Figure 1 and Figure 2 The embodiment in the middle has greater compressive strength in the width direction W, which is due to both the cross-sectional shape of the protrusions 11 and 12 and the fact that the protrusions support each other where they meet at the base segment 10, thus having greater compressive strength.

[0070] Figure 4 Packaging inserts and Figure 1 and Figure 2 Both of the packaging inserts are made by folding a single corrugated cardboard sheet. The two edges of the sheet are formed together. Figure 2 The lower vertical edge and Figure 4 The left longitudinal edge 103a, while Figure 2 The upper longitudinal edge 103 and the right longitudinal edge 103b are formed by creases in the sheet. For example, it can be... Figure 2 and Figure 4As can be vaguely seen, the cardboard has been weakened by passing through intermittent slits in the cardboard midway through the creases forming the longitudinal edge 103b. This facilitates folding and helps provide a straight longitudinal edge for the packaging insert. In both embodiments, the sections of the sheet on which protrusions 11, 12 are formed are attached to the sections forming the base section 10 by means of adhesive. Figure 4 In the embodiment, hot melt adhesive 15 has been used where the two protrusions 11 and 12 are connected to each other and to the base segment, and the hot melt adhesive 15 can be seen.

[0071] Figure 4 In the embodiment of the present invention, the protruding engagement elements 13a and 13b are in Figure 5 and Figure 6 They are magnified and shown from different angles. They are larger than... Figures 1 to 3g The protruding engagement elements are much simpler, mainly formed by the triangular cut-out portion in each of the protrusions 11 and 12. When the base segment 10 is folded at fold line F, the tip segment 131 of the left protruding engagement element 13b enters the recess 134 in the right protruding engagement element 13a, and the tip segment 132 of the right protruding engagement element 13a enters the recess 135 in the left protruding engagement element 13b. When the fold reaches 90 degrees, the ends of the two recesses 134 and 135 engage with each other, and the end surfaces 136 abut against the base segment 10. There is no such... Figures 1 to 3g In the embodiment, the two protruding engaging elements are mechanically locked to each other; however, friction between the tip sections 131, 132 and the legs of the protrusions—the tip sections 131, 132 being inserted below the legs—will hinder the unfolding of the packaging insert. It should be noted that the overlapping sections in this embodiment... Figures 1 to 3g The overlapping sections in the implementation are relatively large, resulting in more friction.

[0072] Figure 7 Another embodiment of the protrusion engagement elements 13a, 13b is shown, in which two sets of protrusions are arranged closely side by side and have as shown in the reference. Figure 4 The cross-sectional shape of the isosceles triangle described. Figure 7 The protruding connecting elements 13a and 13b in the middle are Figures 1 to 3g The protruding engagement elements shown are Figures 4 to 6 The mixture of those protruding engagement elements shown, the first protruding engagement element 13a being substantially shaped as Figures 1 to 3g The protruding engagement elements, and the second protruding engagement element 13b is substantially shaped as follows: Figures 4 to 6 Those protruding connecting elements in.

[0073] exist Figure 7 In one embodiment, the two protrusions in each group have different widths in the height direction and different cross-sectional shapes.

[0074] Figure 8 Another package insert in its unfolded state is shown. Here, one set of protrusions 11 has a cross-sectional shape that is neither a right angle nor an isosceles triangle, while another set of protrusions 12 has a cross-sectional shape that is a right angle triangle. This means that the package insert may need to be used in a specific orientation because the package insert is not symmetrical, and the same package insert can match two different roof window shapes depending on how the package insert is rotated.

[0075] As in Figures 1 to 3g middle, Figure 8 The embodiment also has two sets of protrusions spaced apart by a distance D in the height direction H, and is formed by folding a single cardboard sheet. However, here, the edges of the sheet meet each other in the joint 18 between the protrusions, which means that the two longitudinal edges 103 of the packaging insert are formed by creases in the sheet.

[0076] Figure 8 The packaging insert is shown without a protruding engagement element, but it should be understood that a protruding engagement element will be present and may be implemented, for example, as shown in the previous figures.

[0077] Figure 8 The packaging insert also includes four cutouts 16 at the longitudinal edge 103, which are used to engage with the cardboard box in the packaged state of the roof window.

[0078] exist Figure 9 middle, Figure 8 The packaging insert 1 is shown arranged in the corner of the roof window 2 in a folded state, and... Figure 10 In the middle, the packaging insert 1 and the roof window 2 are arranged in the cardboard box 3.
