Description

Technical Field

[0001] This invention relates to packaged roof window products comprising multiple roof window product-related components of different sizes housed in a box. The box, in its supplied state, has a bottom side and a top side spaced apart along a height axis. A sidewall extends along the height axis between the bottom and top sides of the box, defining an internal space within the box. A first sidewall extends along a main axis perpendicular to the height axis and has an upper edge extending along the main axis along the top side, an outer surface facing away from the internal space, and an inner surface facing the internal space. A first component includes an internal space defined by its inner surface. A second component or a collection of components is housed in a sub-package within the box, the sub-package including a body that defines an internal space for accommodating the second component or the collection of components. The invention also relates to a method for packaging roof window products to be packaged and a method for unpacking packaged roof window products. Background Technology

[0002] When installing windows on a roof, it is crucial to ensure that the roof window itself is securely attached to the roof structure and that the joint between the roof window and the roof structure is properly weatherproof. Therefore, it is essential to use and apply all components of the roof window product, such as the roof window itself or its waterproofing components, in the correct manner. To facilitate this, the components are typically arranged in the box in the intended order of use, and small parts, such as screws, are stored in plastic bags. Furthermore, expanded polystyrene blocks or similar shock-absorbing material blocks are used to protect the product and / or to hold the components in their intended positions within the box. Examples of packaged roof windows using these principles are known from EP2748071B1, and examples of packaged waterproofing components for roof windows are known from EP1710163B1. Typically, small parts are attached to the box or to larger components, for example by means of adhesive, to prevent loss of small parts inside the box or when removed from the box, and / or small parts are contained in sub-packaging such as plastic bags or smaller boxes, thereby also preventing small parts from scratching or otherwise damaging other components. Typically, larger components are held in place in the box by means of adhesives or by fixing them between expanded polystyrene (EPS) blocks that themselves fill the space in the box, for example from one side to the other, or are glued to the box, and some larger components are covered with a plastic protective film to prevent them from being scratched.

[0003] While this works well in protecting the components, a remaining problem is that sub-packages sometimes move around inside the box during handling and transportation, making them difficult to locate when unpacking the roof window product and potentially damaging the product components or their surfaces. To address this, sub-packages and components are attached to the box with glue or adhesive, but glue and adhesive are not easily removed from the packaging material, and when recycling materials containing too many foreign objects, this can lead to the material being classified as a lower-grade material and thus, for example, burned instead of recycled. Summary of the Invention

[0004] In this context, the object of the present invention is to provide a packaged roof window product that has improved recyclability without increasing the risk of errors during product installation, while maintaining good protection of components during transportation.

[0005] These and other objectives are achieved by a first aspect of the invention, which provides a packaged roof window product of the type mentioned in the introduction, characterized in that the sub-package includes an attachment flap protruding from the body, and the sub-package is held relative to the first component by the attachment flap positioned in the interior space of the first component.

[0006] By providing sub-packages with attached flaps, the sub-packages can be attached to a first component that holds the sub-packages in place within the box. This eliminates the need for separate fastening devices for the sub-packages, potentially reducing the number of packages. This increases the likelihood of packaging material recycling by reducing the need for installers to collect and sort different types of packaging after window installation.

[0007] The main body and the attached flaps can be made of the same material to improve recyclability. In the currently preferred embodiment, the entire sub-package is made of a paper-based material.

[0008] Attaching the sub-package to the first component also allows the first component, along with the second component or a collection of components, to be removed from the box as a unit, and thus the components to be used with the first component can be packaged in the sub-package. In this way, the installer has the required components on hand when installing the first component.

[0009] Another potential advantage of holding the sub-package relative to the first component is that the sub-package can be used as a positioning element for the first component in the box, for example, by spacing the first component from another component or from the side wall of the box.

[0010] Suitable, the sub-package is held relative to the first component by means of an attached flap or a segment of the attached flap confined within the internal space of the first component. A confined state occurs when the segment is confined under tension between the inner surfaces of the internal space of the first component. Corrugated cardboard is a suitable material because it has sufficient flexibility to allow deformation when positioned within the internal space of the first component, but also sufficient stiffness to maintain its position once positioned within the internal space.

[0011] In this document, the attachment fold is described with reference to the proximal end of the attachment fold adjacent to the body of the sub-package and the distal end opposite to the proximal end. The distal end of the attachment fold is typically located inside the interior space of the first component, while the proximal end is typically located outside the interior space of the first component. The distal end includes the free edge of the attachment fold.

[0012] The box can be rectangular in shape, with the top and bottom sides extending parallel to each other, and four sidewalls extending perpendicularly to the top and bottom sides between the bottom and top sides. In this case, the height axis is parallel to the sidewalls, two sidewalls extend along the primary axis, and the remaining two sidewalls extend along a secondary axis perpendicular to both the height axis and the primary axis. The primary and secondary axes can represent the longitudinal axis and the transverse axis, respectively.

[0013] The box is preferably a flat box, in which the top and bottom sides form the main sides of the box, and the side walls are the secondary sides. Here, "main" and "secondary" refer to the relative areas of the respective sides. In a flat box, the height is less than the other dimensions, namely length and width. The width can be greater than the length.

[0014] The term "supply state" refers to the packaged state of a roof window product, in which it is supplied to the user. In this document, the box is described with reference to the bottom and top sides, with sidewalls extending between the bottom and top sides. These terms are understood according to their function in packaging the roof window product; the top side is a side that opens during packaging of the roof window product to allow the components to be packed in the box, and is subsequently closed to provide the supply state. The top side can also be referred to as the lid of the box. In the supply state, the box surface facing the interior space is referred to as the inner surface, while the surface facing away from the interior space is referred to as the outer surface.

[0015] In some embodiments, a segment of the attached folding plate spans the interior space of the first component, a first edge of the segment engages the inner surface of the interior space of the first component at a first contact position P1, and a second edge of the segment engages the other inner surface of the interior space of the first component at a second contact position P2, a distance Di is defined between the first contact position P1 and the second contact position P2, and a length Ls is defined between the first edge and the second edge of the segment of the attached folding plate, wherein the length Ls is equal to or greater than the distance Di.

[0016] In this way, the attachment flap is constrained between the first and second contact positions, thereby holding the sub-package relative to the first component. The constraint of the attachment flap is reinforced by a length Ls exceeding the distance Di, causing slight deformation or bending of the flap section to increase the force acting on the first and second contact positions. For some materials, one or more edges of the attachment flap section may be pressed together, similarly increasing the force acting on the contact positions.

[0017] Distance Di is the distance between contact positions P1 and P2, measured in a cross-sectional plane perpendicular to the longitudinal extent of the first component. Similarly, length Ls is the length of the trajectory of a segment of the attached fold extending between contact positions P1 and P2, measured in the same cross-sectional plane. The first or second edge of the segment can be the edge of a folded region in the attached fold, which is defined by two edges. In this case, length Ls is measured between the first edge of the folded region at contact position P1 and the second edge at contact position P2, where the first edge is the edge of the folded region closest to the second edge. The segment of the attached fold can span the interior space or can span along one or more of the interior surfaces.

[0018] Suitablely, the attachment flap folds within the interior space of the first component, and wherein the folded area of ​​the attachment flap includes a first edge and / or a second edge. Folding the attachment flap provides edges other than the edge at the distal end of the attachment flap, said edges which can engage the interior space of the first component to confine the attachment flap within the interior space of the first component. The folded area is a portion of the attachment flap where the attachment flap is folded or bent. Thus, the segments of the attachment flap on each side of the folded area extend in different directions. The folded area can be provided by perforation, scoring, or compression or other weakening of the attachment flap to facilitate folding. The folded area can be provided by weakening the material along a line to provide a relatively narrow folded area. The folded area can also be provided by two spaced-apart weakened lines to provide a wider folded area, for example by two parallel scoring lines in the attachment flap. A wide folded area can also be provided by compressing the material of the attachment flap at the location where the folded area is intended to be positioned. The folded area can have a generally linear range or can have a curved range.

[0019] In some implementations, the first component is a grooved element for a roof window covering or waterproofing assembly.

[0020] Grooved components are commonly used for drainage, such as drainage along the top of a roof window installed in a sloping roof. A groove, located under the roof tiles and on the top of the lower roof supported by the roof structure, drains water onto a waterproof component extending along the side of the window. The grooved component comprises a U-shaped cross-section formed by the various side sections of the component, and the internal space is formed as a concave channel or channel between the various side sections. The side sections of the U-shape can be curved or connected at an angle to each other. The channel or channel in the U-shape, i.e., the internal space of the first component, can suitably have a rectangular cross-section, possibly with rounded corners, which provides parallel surfaces between which the attached folding plate can be confined. Alternative cross-sections for the channel or channel in the U-shape, such as trapezoidal or curved cross-sections, can also be used. It is conceivable that groove elements with a V-shaped cross-section can also be used.

[0021] In one embodiment, the attachment fold has a proximal end adjacent to the body of the sub-package and a distal end opposite to the proximal end, and the groove-shaped first component includes a U-shaped cross-section formed by a first side segment, a second side segment, and a third side segment, the first and second side segments being positioned on opposite sides of the interior space of the first component, and the third side segment connecting the first and second side segments, wherein an open fold is provided at the free edge of the first or second side segment, and the distal end of the attachment fold is disposed in the open fold.

[0022] By providing an open flange on the first component, the distal end of the attached folding plate can be inserted into the open flange to retain the attached folding plate within the interior space of the first component. The open flange can form the second contact position P2 described above, and a portion of the folding plate can be confined between the open flange and another contact position within the interior space of the first component. Alternatively, the open flange can retain the attached folding plate by itself, by its distal end tightly fitted within the open flange, or by confining the distal end within the open flange. The term open flange refers to an edge that bends itself at a distance from the side section of the first component or otherwise bends to create a gap.

[0023] Conversely, a closed fold refers to a fold without gaps at the point of contact with the side section. A closed fold can also provide a suitable contact position for the edge of an attached folding plate.

[0024] This type of folding is common for metal parts to reinforce edges or conceal sharp edges, and therefore eliminates the need for specially designed components. Folds can be formed by folding the edges of components, such as sheet metal parts, but can also be incorporated into die-casting processes, etc.

[0025] In some embodiments, the attachment flap is held or restricted by its distal end, which engages with the inner surface of the interior space of the first component at a corner formed by two inner surfaces angled together. Such a corner can be provided, for example, by giving a side segment of the first component a curved edge that forms a boom extending from that side segment at approximately 90 degrees. The term “angled together” as used herein does not necessarily mean that the surface or side segment is a separate component that has been attached to form a combined element, but rather refers to a surface or side segment that extends at an angle relative to each other.

[0026] Such a corner can provide a suitable contact position for the edge of the attached fold, at which the edge is unlikely to slide on the inner surface.

[0027] In some embodiments, the attachment flap has a first section close to the body and a second section away from the body, wherein the first and second sections are defined by a folded area of ​​the attachment flap. Such an attachment flap can be held within a first component having a U-shaped cross-section by the first and second sections contacting the opposing side sections at their free edges. The attachment flap will have a tendency to unfold at the folded area, which can provide sufficient force acting on the first and second sections to keep them in contact with the first component and hold the sub-package. This can be achieved, for example, by an attachment flap made of corrugated cardboard, in which the folded area is a compression area of ​​the attachment flap.

[0028] In some implementations, the first component is supported by the first sidewall of the box.

[0029] By having the first component carried by the sidewall, the height of the box can be utilized to a greater extent, allowing for, for example, a reduction in the box's width. This can reduce material consumption, resulting in a smaller climate footprint, and may also create greater flexibility in handling, storage, and transportation. Another potential advantage is that, since the first component is held in place within the box via the sidewall, and therefore the sub-packages are also held in place via the sidewall, auxiliary fastening devices such as adhesives, tapes, or straps can be eliminated, potentially making the packaging more suitable for easy recycling. It should be understood that the first component is carried by the first sidewall without using fastening devices beyond the box itself; that is, the first component can be suspended or dangled from the first sidewall. The component can be said to be freely suspended from the first sidewall. Therefore, the first component is carried by the first sidewall through engagement between the first component and the sidewall and any other possible panels of the box, such as the lid of the box when closed.

[0030] The first component can typically be supported by the first sidewall, which is located within a portion of the internal space of the first component.

[0031] In one embodiment, the first component is supported by the upper edge of the first sidewall, and the attachment flap of the sub-package is folded from the inner surface of the first sidewall across the upper edge to the outer surface of the first sidewall.

[0032] By placing the first component on the upper edge, the first component is suspended from the side wall, thus providing a position facing the top side of the box in the supplied state. Additionally, when the box is closed in the supplied state, the lid of the box will contact the first component, and friction between the first component and the lid prevents the first component from sliding along the side wall. In this way, the first component is effectively secured in the box without the use of auxiliary fastening devices extending beyond the box itself, and therefore the sub-packages are also effectively secured in the box without the use of auxiliary fastening devices extending beyond the box itself, thereby potentially reducing the amount of packaging material used. In such an embodiment, an attachment flap is arranged between the inner surface of the first component and the upper edge of the first side wall.

[0033] The upper edge is the free upper edge of the panel forming the sidewall of the box. The edge can be formed by folding between two panels of the box, or alternatively by forming it as the end of a panel. The term "upper" refers to a position upward along the height axis, i.e., towards the top side of the box. Suitablely, the first component is suspended from the upper edge by extending along it. The first component can engage and rest on the upper edge of the sidewall, but particularly in embodiments where two or more sub-packages are held by the first component, the first component can rest on the attachment fold of the sub-packages and not be in direct contact with the upper edge of the first sidewall.

[0034] In one embodiment, a side segment of the first component overlaps with the outer surface of the first sidewall, and the lid of the box includes an overlapping panel that overlaps with the outer surface of the first sidewall in a supplied state, such that the overlapping side segment of the first component is positioned between the first sidewall and the overlapping panel.

[0035] In this way, the first side section of the first component is covered by the overlapping panel, and the friction between the overlapping panel and the component reduces the tendency of the component to slide on the first sidewall. Essentially, the first side section is sandwiched between the first sidewall and the overlapping panel. In the case of a five-panel folding cardboard box, the overlapping panel can be a folding plate, or in the case of a collapsible cardboard box, the overlapping panel can be a cover sidewall. In the closed state of the box, the overlapping panel is suitably secured to the sidewall, preferably by adhesive.

[0036] A five-panel folding box (sometimes called a five-panel folding piece) is a standard box type, in which the fifth panel is configured to overlap with another panel when the box is closed. A collapsible box is also a standard box type, in which the box comprises two pieces that can cooperate with each other such that the sidewall of one piece overlaps with the sidewall of the other piece.

[0037] In another improvement, the overlapping panels and / or the first sidewalls are provided with a region of reduced thickness, such as a compression region, and this region corresponds in size and shape at least to the first side segment of the first component. This region provides space for the first side segment, and also prevents proper attachment of the adhesive used to attach the overlapping panels to the first sidewalls, or subsequent disruption of the adhesive bond by forcing the overlapping panels away from the sidewalls.

[0038] In another improvement, the first sidewall includes a receiving section, wherein the first component is carried by the receiving section. Suitably, the receiving section is a recess in the upper edge of the first sidewall.

[0039] By providing recesses in the sidewalls, the first component can be positioned in a retracted position relative to the top side of the box, allowing the box to close flush. Furthermore, the first component can be positioned between the ends of the recesses, which hold the first component in place to prevent it from sliding along the sidewalls in the direction of the main axis. In such an embodiment, the length of the recesses approximately corresponds to the length of the first component.

[0040] In some embodiments, the first sidewall has a length L along the main axis, and the first component extends over 20% to 90% of the length L, preferably over 50% to 90% of the length L.

[0041] In some embodiments, the attached folding plate extends into the interior space of the first component through an opening in the first component, and the segment of the attached folding plate positioned inside the interior space of the first component has a length La, which is greater than the dimension Do of the opening in the first component. Both the length La and the dimension Do extend in the same cross-sectional plane. This cross-sectional plane is perpendicular to the longitudinal extent of the first component, which is parallel to the main axis if the first component is supported by a first sidewall. The segment of the attached folding plate positioned inside the interior space of the first component can be, for example, the second segment described above, a folded region, or a segment formed by the folded region and the second segment together. Since the segment inside the interior space is larger than the dimension of the opening, the segment of length La can act as a support within the interior space. For a component with a U-shaped cross-section, the free edges of the first and second side segments define the opening, and the distance Do is the distance between the free edges in the cross-sectional plane.

[0042] In some implementations, the box and / or sub-packages are made of paper-based materials, such as cardboard or paperboard, preferably corrugated cardboard.

[0043] Cardboard and other paper-based materials are readily recyclable, and by providing all packaging elements made from such materials, the likelihood of recycling is significantly increased because it eliminates the need to sort the packaging into smaller parts. Cardboard can also be manufactured in a way that allows it to be suitably compressed to force it into the interior space of the first component, and is rigid enough to subsequently hold the cardboard in its position within the interior space of the first component, thus keeping the sub-package in place. Corrugated cardboard can also be easily folded at a pre-selected location by compression, perforation, or scoring. In this way, the length of the section to be confined or restrained within the interior space can be predetermined based on the dimensions of the interior space. As described above, corrugated cardboard can also be made rigid enough to hold the attached fold by inserting the distal end into the open fold of the first component.

[0044] In one implementation, the attached flap is integrally formed with the main body of the sub-packaging. In this way, the likelihood of actual recycled material in the sub-packaging material is significantly increased, while also simplifying the manufacture of the sub-packaging.

[0045] In some implementations, the subpackage includes a removable portion configured to separate from the rest of the subpackage via a break area. The break area is understood as a portion of the subpackage that has been intentionally weakened to facilitate tearing, opening, etc., of the subpackage. The break area may include perforations or scoring. By providing the removable portion, installers can easily remove the subpackage from the first component. The removable portion also provides installers with an easy way to open the subpackage and access the components housed within it.

[0046] In embodiments where the attachment flap remains within the first component but is flexible enough to be removed from the first component without breakage, the removable portion can be configured to remain attached to the remainder of the sub-package after it has been opened. In this way, the sub-package is maintained as a single unit, thereby increasing the likelihood that material can be collected for recycling.

[0047] The removable portion may include an attachment fold. When the removable portion includes an attachment fold, a break area is provided at or connected to the attachment fold. In this way, the break area provides a means of separating the body from the attachment fold, from which the attachment fold can therefore remain in the first component. The break area may be provided on a wall of the body from which the attachment fold protrudes. The removable portion may cover at least 30%, preferably at least 50%, of the wall of the body from which the attachment fold protrudes. In this way, the removable portion provides an opening through which an installer can easily remove components from the sub-package, the opening being provided as the body separates from the first component. The coverage of the removable portion is calculated as a fraction of the area removed from the wall of the body to the total area of ​​the wall.

[0048] In some embodiments, the body of the sub-package is box-shaped. The box shape is typically a rectangular prism shape. In alternative embodiments, the sub-package includes one or two open sides facing along the main axis. Such a body can have a tubular or pipe-like shape. In a body with two open sides, the open sides preferably face opposite directions along the main axis to allow long components to be accommodated by extending through the body. A body with one open side can accommodate the end portion of a component, and therefore two sub-packages can accommodate one component.

[0049] The sub-package can be suitably folded from a blank, such as a five-panel folding blank. In this case, the attachment fold is set as an extension of one of the side panels of the blank.

[0050] In some implementations, the sub-package is a bag, such as a paper bag. The attachment flap may be an extension of part of the bag, or a separate attachment flap suitable for use with cardboard or corrugated cardboard attached to the bag.

[0051] In one embodiment, the attachment flap includes a thick portion having a thickness configured to be held within the interior space of the first component. This can be achieved by the thickness of the thick portion corresponding to or slightly exceeding the distance between the inner surfaces of the first component, whereby the thick portion can be held by tension between the inner surfaces. In an embodiment where the first component is supported by a first sidewall of the box, the thickness of the thick portion can be configured to be held between the inner surface of the first component and the surface of the first sidewall. The thick portion can be formed by folding the attachment flap onto itself, or alternatively by attaching a piece of material, such as cardboard or corrugated cardboard, to the attachment flap to increase the thickness. This piece can be attached using, for example, adhesives, glue, or the like.

[0052] In some embodiments, the box is formed by folding one or more blanks, which are preferably five-panel folding blanks or stacked blanks.

[0053] In another aspect of the invention, a method for packaging a roof window product as described herein is provided, the method comprising the steps of: arranging a sub-package in a box, wherein an attachment flap extends from an inner surface across a first sidewall to an outer surface, and arranging a first component on the first sidewall, wherein the attachment flap is positioned within the interior space of the first component to hold the sub-package relative to the first component.

[0054] When the attachment fold is positioned across the first sidewall and the first component is arranged on the attachment fold, the attachment fold will be positioned in the interior space and will be held or confined in the interior space.

[0055] In another aspect of the invention, a method for unpacking a packaged roof window as described herein is provided, the method comprising the steps of: removing a first component from a box, wherein a sub-package is held relative to the first component, and at least removing the body of the sub-package from the first component.

[0073] First refer to Figure 1 , Figure 1 A perspective view is shown from above of the packaged roof window product 1, contained in a five-panel folding cardboard box 10. The cardboard box is shown in an open state, with the lid forming the top side 11 open. The box 10 has a rectangular configuration and has a bottom side 12 and four side walls 13 to 16 extending along a height axis H perpendicular to the bottom side 12. A first side wall 13 and a second side wall 14 extend along a primary axis P between side walls 15 and 16. Side walls 15 and 16 extend along a secondary axis S, and both the primary axis P and the secondary axis S are perpendicular to the height axis H and to each other. The primary axis P is longitudinal, and the secondary axis S is transverse. The top side 11 and the bottom side 12 are considered as the main sides of the box. The box 10 has an internal space capable of accommodating multiple window product-related components 2, with most of the components resting on the bottom side 12. Components 2 include waterproofing components, insulating frame side members, and grooved elements 3. The grooved element 3 is implemented as a first component and is supported by a first sidewall 13. The grooved element 3 is suspended from the upper edge 131 of the first sidewall 13. The grooved element 3 has an internal space and is arranged such that the first sidewall 13 extends into the internal space. A collection of smaller components is accommodated by a sub-package 5, which is positioned below the grooved element 3 at the first sidewall 13. Attachment folding plate (in Figure 1 (Not visible in the center) Folded inside the grooved element 3 and across the first sidewall 13, thereby holding the sub-package 5 relative to the grooved element 3, which in turn holds it relative to the first sidewall 13. Details of the positioning of the attachment fold within the grooved element are shown in subsequent figures. See also Figure 16 , Figure 16 Box 10, which does not contain component 2, is shown from another angle.

[0074] Now refer to Figure 2 , Figure 2Details of the sub-package 5 in the box 10 before the grooved element 3 is mounted on the first sidewall 13 are shown. The first sidewall 13 has a receiving section formed by a recess 22 from which the grooved element 3 is suspended. The grooved element 3 extends between two recessed ends 211, which prevents the grooved element 3 from sliding along the first sidewall 13. In addition, the recess 22 provides a retracted position of the grooved element relative to the top side 11 of the box in the supplied state, thereby allowing the top side to close flush. The sub-package is positioned close to the first sidewall 13, wherein the body 51 abuts against the inner surface 132 of the first sidewall, and an attachment flap 52 is arranged to extend from the inner surface 132 across the first sidewall 13 to the outer surface. The attachment flap 52 has a first section 521 extending between a proximal end 521a at the body 51 and a folding area 522, and a second section 523 extending from the folding area 522 to a distal end 523a furthest from the body 51. Therefore, the first segment 521 and the second segment 523 are defined by a folding region 522, where the material has been compressed to facilitate folding. When the groove element 3 is installed in the recess 22, the second segment 523 will fold downward along the outer surface of the first sidewall 13, and the attached folding plate will be confined within the internal space of the groove element 3.

[0075] Now refer to Figures 3a to 3b ,in, Figure 3a The steps of packaging components are shown, wherein sub-package 5 is arranged in box 10, and Figure 3b The subsequent steps are shown, wherein the trench element 3 is packaged within the box 10. Figure 3a In the middle, the sub-package 5 is placed at the first side wall 13, wherein the attached folding plate 52 is as follows Figure 2 As shown, it is arranged above the upper edge 131. The trench element has a first side section 34 and a second side section 35 connected by a third side section 36. The first side section 34 is... Figure 3b The first side segment 34 is not visible because it is obscured by the second side segment 35 and the first sidewall 13. The first side segment 34, the second side segment 35, and the third side segment 36 define the internal space of the trench element 3. Figure 3b When the groove element 3 is positioned on the first sidewall 13, the first sidewall 13 extends into the interior space of the groove element 3, and the first side segment 34 of the groove element overlaps with the outer surface 133, while the second side segment overlaps with the inner surface 132. When the groove element 3 is positioned on the first sidewall 13, the second segment 523 of the attachment fold folds downward along the outer surface 133 and the first side segment 34, and the attachment fold 52 is confined within the interior space of the groove element 3. Therefore, the attachment fold folds below the groove element 3 across the upper edge 131. As can be seen, the sub-package 5 is suspended above the bottom side portion 12, indicating that the sub-package 5 is held in place relative to the first sidewall 13 by being held relative to the groove element 3.

[0076] Figure 4 It is shown in an illustrative manner Figure 3b The cross-section of the groove element 3 in a plane extending perpendicular to the main axis is shown. The groove element 3 has a U-shaped cross-section formed by a first side segment 34, a second side segment 35, and a third side segment 36. The inner surfaces 34s of the first side segment, 35s of the second side segment, and 36s of the third side segment define the internal space 37 of the groove element, which is a concave channel or groove extending along the main axis P. The attachment fold 52 is folded inside the internal space 37 at the folding region 522. The second segment 523 spans the internal space 37, and the edge of the second segment 523 at the folding region 522 engages the inner surface of the internal space at the first contact position P1, and the distal end 523a engages the inner surface at the second contact position P2. The distance between the contact points P1 and P2 of the inner surfaces is shown as distance Di. As can be seen, in this embodiment, the length Ls of the second segment is substantially equal to the distance Di, thereby confining the second segment 523 within the internal space 37 with minimal tension. In other embodiments, the length Ls exceeds the length Di, thereby further confining the second segment 523 between the first contact position P1 and the second contact position P2. In this embodiment, the folded area 522 is a wide area, which can be pre-formed by compressing the attachment fold or by scribing the attachment fold along the two folded area lines. In other embodiments, the folded area can be narrower than shown to reduce the contact area with the inner surface. This can be achieved, for example, by individual scribing lines or compression lines in the attachment fold. When the grooved element 3 is removed from the first sidewall 13, the sub-package 5 remains attached to the grooved element 3 because the attachment fold 52 is confined between the inner surfaces by the tension of the second segment 523. The grooved element 3 here is a component with folded edges 34a, 35a, which provide smooth reinforcing edges and provide an open fold that supports the distal end 523a at P2.

[0077] Figure 5 As shown Figure 4 The sub-package 5, which holds the grooved element 3 within the box, is in a supplied state with the lid 11 closed. The lid 11 contacts the grooved element 3 to provide additional fixation of the grooved element 3 to the first sidewall 13. The lid has an overlapping panel 111 for closure by abutting the outer surface 133 of the first sidewall with an adhesive strip 40. The overlapping panel 111 includes a region 112 with a reduced thickness corresponding to the size of the first side segment 34 to reduce stress on the overlapping panel 111 in the supplied state.

[0078] Now refer to Figure 6 and Figure 7 , Figure 6 and Figure 7 The blank for the sub-package 5 and the sub-package 5 folded from the blank are shown separately. The blank here is a five-panel folding type, wherein the main body 51 is formed by a cover panel 501, a bottom panel 503, two side panels 502, 504, and six side folds 505 that will form the remaining two side walls. Dashed lines indicate fold lines. In this embodiment, the side folds 505 are glued together in the folded state to form the main body 51. As an alternative to glue, the blank may have interlocking panels. The cover panel 501 has an overlapping panel 506 that is glued to the side folds 505 in the folded state to close the sub-package 5. The blank also has a panel 507 that extends below the cover panel 501 in the folded state and can be glued to the cover panel 501.

[0079] The attachment fold 52 is integral with the main body 51 and is an extension of the cover panel 501. The first segment 521 and the second segment 523 are defined by a folding region 522, indicated by a dashed fold line. The position of the folding region is predetermined, i.e., the folding region is set as part of the blank, which allows control over the dimensions of the first segment 521 and the second segment 523. In this way, it can be ensured that, for example, the second segment 523 of the attachment fold 52 is sized to be suitable for confining it within the internal space of the groove element. However, it should be understood that this is not necessary, and the attachment fold can be folded, and the folding region 522 is defined by the force applied when the first component is placed on the first sidewall 13 as described above.

[0080] Sub-package 5 also has a removable portion 54, which includes an attachment flap 52 and a portion of the cover panel 501 defined by a break area 541. The break area is shown here as a perforated line 541 in dashed form. Therefore, the removable portion 54 is a weakened portion of the cover panel, and by tearing the attachment flap 52 from the main body, a portion of the cover panel 501 is torn off along with the attachment flap 52 to provide an opening in the sub-package 5 through which the contents can be removed. In this embodiment, the removed portion of the cover panel 501 covers approximately 70% of the area of ​​the cover panel 501. The removable portion 54 allows the operator to easily tear the sub-package 5 from the groove element 3 while simultaneously opening the sub-package 5, the removable portion 54 being held in the groove element 3 by the attachment flap 52. When the removable portion 54 is removed, the panel 507 also serves to prevent components from accidentally falling out of the sub-package.

[0081] Now refer to Figure 8a , Figure 8aThe groove element 3, which has been removed from the first sidewall (not shown), is illustrated. The groove element 3 is shown schematically, excluding its entire length, with portions of the groove element drawn in dashed lines. As can be seen, the sub-package 5 is held together with the groove element 3 by an attachment flap 52 inside the groove element 3 and has detached from the first sidewall along with the groove element. Figure 8b As shown, by tearing the main body 51 of the sub-package 5 from the groove element, the removable portion 54 remains in the groove element 3 when the sub-package separates at the break area 541. At the same time, an opening is provided in the cover panel 501 of the sub-package 5, through which the assembly 55 of the components can be removed.

[0082] Now refer to Figure 9 , Figure 9 An alternative embodiment of sub-package 5 is shown, in which the main body 51 is box-shaped and has open sides 511. The open-side sub-package can be used for long components, where only a portion of the component is housed within the interior space of the sub-package. For example, two sub-packages, each having one open side 511, can accommodate either end of the long component. Alternatively or additionally, the component can extend through one or more sub-packages having two open sides facing opposite directions along the main axis P.

[0083] Now refer to Figure 10 , Figure 10 The grooved element 3, which has been removed from the box, is shown, wherein the sub-package 5 is still held relative to the grooved element 3 by a second segment 523 confined between a first contact position P1 and a second contact position P2. The length La of the second segment, as seen in the bending displacement trajectory of the segment 523, exceeds the distance Di, and the second segment 523 exhibits a deformable shape. This can be achieved using a flexible material, such as cardboard.

[0084] Now refer to Figure 11 , Figure 11 The image shows the grooved element 3 after it has been removed from the box, wherein the sub-package 5 is still held relative to the grooved element 3 by a second segment 523 of an attachment fold, the length La of which is greater than the dimension Do of the opening in the grooved element 3. Both the length La and the dimension Do extend in the same cross-sectional plane.

[0085] Now refer to Figure 12 , Figure 12The sub-package 5 is shown to be held to the groove element 3 by the distal end 523a of the attachment fold, which is inserted into and engaged with the open flange 38 formed at the free edge of the first side segment 34 via a folded edge 34a on its free edge. The distal end 523a fits tightly into and is confined within the open flange 38, and because the attachment fold is made of sufficiently rigid corrugated cardboard, it maintains its position in the internal space even when the folded area 522 does not contact the inner surface of the groove element.

[0086] exist Figure 4 , Figure 11 as well as Figure 12 In each of the figures, the distal end 523a of the attachment plate 52 can be said to engage the inner surface of the groove element at a corner formed by two inner surfaces connected at an angle to each other. In an alternative embodiment where the groove element has a V-shaped cross-section, the edge of the attachment plate may engage at the corner at the top of the V-shape.

[0087] Now refer to Figure 13 , Figure 13 A corrugated cardboard sub-package 5 is shown, wherein a second segment 523 crosses the interior space of the grooved element 3 constituting the first component along the inner surface of the third side segment 36 between contact positions P1 and P2. The position of the folded area 522 has been pre-selected such that the second segment is confined between the first side segment 34 and the second side segment 35 of the grooved element.

[0088] Now refer to Figure 14 , Figure 14 A grooved element 3 is shown installed together with and above a pair of roof windows 100. The grooved element 3 is an exemplary embodiment of a component having an interior space, as described herein, in which an attached folding panel can be held and supported by a first side wall of the box. Other components having a cross-sectional shape that includes at least two side segments extending at an angle to each other to form a concave interior space may also be used.

[0089] Now refer to Figure 15a and Figure 15b , Figure 15a and Figure 15b Another embodiment of the corrugated cardboard sub-package 5 is shown. The second segment 523 of the attachment fold is folded onto the first segment 521 to provide a relatively thicker portion of the attachment fold 52, which can be as follows: Figure 15bThe attachment is fixed between the first side section 34 and the second side section 35 of the groove element 3. In this embodiment, the thick portion is formed by scribing and folding the attachment plate, but it can also be formed by attaching an additional cardboard piece to the attachment plate 52. The thickness of the thick portion here is twice the thickness of the attachment plate 52. The thickness of the attachment plate is the thickness of the corrugated cardboard sheet forming the attachment plate. In this embodiment, the thickness of the attachment plate 52 is such that the thick portion conforms to the internal dimensions of the first component, such as the groove element 3, so that the attachment plate 52 is held between the inner surface 34s and the inner surface 35s. Alternatively, in an embodiment where the first component is supported by the first sidewall 13, the thickness of the attachment plate is selected such that the thick portion of the attachment plate is held between the first sidewall 13 and the side section of the first component, for example, between the inner surface 132 of the first sidewall and the inner surface 35s of the second side section. Figures 15a to 15b In the sub-package 5, the main body 51 is open, and the assembly 55 of the components is packaged in a plastic bag attached to two folds of the main body 51. However, the embodiment with thicker attached folds can also be used in other embodiments of the sub-package, such as box-type sub-package.
