DESCRIPTION OF EMBODIMENTS
[0056] Referring initially to FIG. 1 which shows a perspective view from above of a packed roof window product 1 packed in a box 10 of cardboard and of the five-panel fold type. The cardboard box is shown in an open state where a lid forming the top side 11 is open. The box 10 has a rectangular configuration and has a bottom side 12 and a four side walls 13-16, which side walls extend along a height axis H which is perpendicular to the bottom side 12. A first of the side walls 13 extends between side walls 15-16 along a primary axis P. Side walls 15-16 extend along a secondary axis S, the primary and secondary axis being perpendicular to the height axis and mutually perpendicular. In the embodiment of FIG. 1, the primary axis is longitudinal, and the secondary axis is transverse. The box 10 has an internal space which accommodates a plurality of window product related components 2. In this embodiment the components 2 include a flashing assembly and insulation frame side members, a gutter element 3 and a collection of components packed in a sub-packaging 5. The sub-packaging 5 is here a cardboard box which has an attachment flap (not visible) which is folded across an upper edge 131 of the first side wall 13 below the gutter element 3, whereby it extends from an inner surface (not shown) of the first side wall 13 to an outer surface 133 of the first side wall 13.
[0057] In the supply condition the lid 11 is closed and the attachment flap will be locked in between first side wall 13 and the gutter element 3 by the top side 11. In this way the sub-packaging 5 is fixated in relation to the box 10 without the use of auxiliary fastening means. See also FIG. 16 showing the box 10 from another angle without the collection of components 2.
[0058] The lid 11 of the box further comprises an overlap panel 111 which is attached to the outer surface 133 of the first side wall 13 in the supply condition.
[0059] Referring now to FIGS. 2a and 2b showing perspective views from respectively inside and outside of two embodiments of a box 10 with a sub-packaging 5 being packed therein. The sub-packaging 5 is identical in the two figures and comprises a main body 51 which accommodates a collection of components. The main body 51 is here a box shaped as a rectangular prism. The attachment flap 52 projects from the main body 51 and is in this embodiment an extension of the wall of the main body which rests against the first side wall 13. The attachment flap is here shown as a thin material, but in practice the attachment flap 52 will usually be made from the same material as the main body, such as from corrugated cardboard. The attachment flap 52 has a first section 521 proximal to the main body 51, which first section 521 extends along an inner surface 132 of the first side wall, and a folding zone 522 by which the attachment flap 52 is folded across the upper edge 131 of the first side wall 13. When the attachment flap is folded across the first side wall, a second section 523 extends along the outer surface 133 of the first side wall as seen in FIG. 2b. The sections 521, 523 of the attachment flap are in contact with respective surfaces 131, 133 of the first side wall 13. When all components have been packed in the box 10, the lid (not shown) is closed and an overlap panel (not shown) is glued to the outer surface 133 of the first side wall 13, sandwiching the second section 523 in between the overlap panel and side wall as shown in FIGS. 3 and 4. In the embodiment of FIG. 2a the first side wall 13 is provided with a recess 21 and the attachment flap 52 is folded across an upper edge 131 of the first side wall so that it is located in the recess, whereas in FIG. 2b the first side wall 13 has a uniform height. The recess 21 is provided for suspending the gutter element 3 as shown in FIG. 1. The sub-packaging 5 is here shown in a configuration where it is suspended from the first side wall 13, leaving room between the main body 51 and the bottom side 12 which could potentially be used for other components. Alternatively, the sub-packaging can rest on the bottom side 12.
[0060] Referring now to FIGS. 3 and 4 which show cross sections of a side of the box in the supply condition as seen along the primary axis. The lid 11 and the overlap panel 111 fixates the attachment flap to the first side wall 13 by being in contact with the folding zone 522 and second section 523 of the attachment flap. The sub-packaging 5 is here made from a material which is thinner than the material of the box 10, but in practice both may be made from cardboard having similar or equal thickness. The overlap panel 111 is fastened to the outer surface 133 of the first side wall by a strip of glue 40. In FIG. 3 the cardboard material is sufficiently flexible for allowing it to be slightly deformed at its lower end, to accommodate the attachment flap. FIG. 4 shows an alternative embodiment where the overlap panel has a zone of reduced thickness 112, which corresponds in size to the second section 523 of the attachment flap. In this way space is provided for the second section 523, reducing or eliminating the strain on the overlap panel 111 caused by the second section 523 thereby potentially improving the attachment through strip of glue 40. The zone 112 is here a compressed zone but might also be made in other ways, for example by removal of material.
[0061] Referring now to FIGS. 5a-b which show perspective views of a sub-packaging 5 of corrugated cardboard being packed in a box 10 of corrugated cardboard. In FIG. 5a the attachment flap 52 is folded across the upper edge 131 of the side wall, and in FIG. 5b a gutter element 3 has been positioned over the attachment flap 52 riding on the upper edge of the first side wall 13.
[0062] The attachment flap 52 is in this embodiment longer than the main body 51 of the sub-packaging 5. The attachment flap has length Lf and the main body has length Lb, both measured along the primary axis P when the sub-packaging 5 positioned at the first side wall 13. The longer attachment flap 52 increases friction, preventing the sub-packaging 5 from sliding along the first side wall 13, and also hinders rotation about the secondary axis S.
[0063] Referring now to FIG. 6 which shows an embodiment wherein the attachment flap 52 extends across the first side wall 13 by extending through a cut 134 in the first side wall 13, said cut being made in continuation of a recess 21. By providing the cut 134 the sub-packaging may also be prevented from moving around during the packing process, making it easier for the operator to pack the window related product. The cut also provides a predetermined position for the sub-packaging and thus serves as a guide for the operator in positioning the sub-packaging.
[0064] Referring now to FIGS. 7 to 9 showing embodiments where the attachment flap 52 is provided with lock panels 524 (only visible in FIGS. 7 and 9) for locking the sub-packaging to the first side wall 13. FIGS. 7 and 8 show embodiments of lock panels 524 provided by cuts in the attachment flap 52 and FIG. 9 shows an embodiment where the lock panels 524 project from the attachment flap 52.
[0065] In the embodiment of FIG. 7 the first side wall 13 is provided with two cuts 135 and 136 along the primary axis. The lower cut 136 is not visible in FIG. 7, but is similar to the cut 136 in FIG. 8, as it is shorter than the upper cut 135 and is thus covered by the first section 521 of the attachment flap. The sub-packaging 5 is attached by inserting the attachment flap 52 through the upper cut 135, such that the attachment flap 52 extends across the first side wall 13. Then the attachment flap 52 is folded down with the lock panels folded towards each other, and inserted through the lower cut 136, whereupon the lock panels 524 are unfolded on the inside of the box 10. As the lower cut 136 is shorter than the upper cut 135, the unfolded lock panels prevent the attachment flap from being retracted from the lower cut 136 and the sub-packaging is thus fixated to the first side wall 13.
[0066] FIG. 8 shows an alternative design employing only one cut 136, where the attachment flap is locked in cut 136 by unfolding lock panels 524 as shown in and described with reference to FIG. 7 and is then folded across the upper edge 131 of the first side wall 13.
[0067] FIG. 9 shows an embodiment where projecting lock panels 524 are to be inserted through a pair of cuts 136 extending along the height axis to lock the sub-packaging 5 to the first side wall 13. The lock panels 524 each have an indentation to improve retainment of the lock panels 524 in the first side wall 13. The sub-packaging 5 is here shown in an embodiment, which rests on the bottom side 12 of the box. Embodiments having lock panels 524 can be used if a more secure fixation of the sub-packaging is desired, but embodiments wherein the attachment flap is simply folded across the first side wall 13 and fixed by overlapping panels as shown in FIGS. 2a to 4, and not weaved in the to the side wall, will be sufficient for most components.
[0068] Referring now to FIGS. 10 and 11 which shows a blank for a sub-packaging box 5 and sub-packaging box 5 folded from said blank, respectively. The blank 5 is here of the five-panel fold type, where the main body 51 is formed by a lid panel 501, a bottom panel 503 and two side panels 502, 504 as well as six side flaps 505 which will form the remaining two side walls. The dashed lines represent folding lines. In this embodiment the side flaps 505 are to be glued together in a folded state to form the main body 51. As an alternative to glue, the blank could have interlocking panels. The lid panel 501 has overlap panels 506 which in the folded state are glued to the side flaps 505 to close the sub-packaging 5. The blank further has panel 507, which in the folded state extends beneath the lid panel 501 and may be glued thereto.
[0069] The attachment flap 52 is integrated with main body 51, being an extension of the lid panel 501. The first section 521 and second section 523 are delimited from each other by a folding zone 522 which is indicated by dashed folding lines. The sub-packaging 5 further has a removable portion 54, which here includes the attachment flap 52 and a portion of the lid panel 501, which removable portion 54 is delimited by a break-zone 541 provided on the lid panel 501. Lid panel 501 is the wall of the of sub-packaging 5 from which the attachment flap 52 projects. The break zone is here perforation lines 541 which are shown as dotted lines. The removable portion 54 is thus a weakened portion of the lid panel and by tearing the attachment flap 52 from the main body, a part of the lid panel 501 will be torn away with the attachment flap 52, providing an opening in the sub-packaging 5 through which the contents can be retrieved. In this embodiment, the part of the lid panel 501, which is removed, covers about 70% of the area of the lid panel 501. In embodiments where the sub-packaging 5 is released from the first side wall of the box upon opening on the box, such as the ones shown in FIGS. 2a to 4, the attachment flap 52 provides leverage for the operator, facilitating the opening of the sub-packaging. In other embodiments, where the sub-packaging 5 is securely fixed to the first side wall also when the box is open, e.g. by lock panels as in FIGS. 7 to 9, the removable portion 54 allows the operator to simply tear the sub-packaging 5 from the first side wall 13 while at the same time opening the sub-packaging 5. As the attachment flap 52 is thus left behind on first side wall 13 there is no need to separately collect it for recycling and the likelihood of it being blown away by wind at the installation site is reduced, increasing the likelihood that it will be recycled. The panel 507 may also serve to keep the components from inadvertently falling out of the sub-packaging when the removable part 54 is removed.
[0070] A sub-packaging 5 opened by tearing a cardboard material at a break-zone in the manner described above is shown in FIG. 14. In this embodiment the break-zone extends along the joint between panels 501 and 502. The removable portion 54 (shown in part in FIG. 14) has been separated entirely, but this need not be the case. The component 55 accommodated in the sub-packaging has been exposed but is still retained by panel 507.
[0071] Referring now to FIGS. 12 and 13 showing another embodiment of a box-shaped sub-packaging 5 which is provided with an open side 511 and a blank for folding such a sub-packaging respectively. The blank 5 of FIG. 13 has a panel 501 which is provided with a cut-out 509 in which interlocking flaps 508 can lock in the folded state. Open-sided sub-packaging can be used for long components where only part of a component is accommodated in the internal space of the sub-packaging. For example, two pieces of sub-packaging each with one open side can accommodate either end of a long component. Alternatively, or additionally, the component can extend through one or more sub-packaging with two open sides.
[0072] In the shown embodiments the box 10 is of the five-panel fold type, where the lid 11 is hinged at one of the side walls and is provided with overlap flaps 111 to be attached the outer surface of the remaining side walls. Other types of box-designs could also be used, such as a telescopic box design, where the box formed by two separate parts; a bottom part forming the bottom side and side walls of the box and a top part forming the top side and having overlap panels which in the supply condition overlap at least partly with the side walls of the side walls of the bottom part.
[0073] In FIGS. 1-14, the sub-packaging 5 has been shown as boxes with a rectangular prism shape. Other shapes can be used depending on the component(s) to be accommodated, such as tubular shapes or irregular shapes such as a paper bag. In the embodiment of FIGS. 15a and 15b the sub-packaging is a paper bag 5 in the process of being attached the first side wall 13. The main body 51 has an irregular shape and is positioned at the inner surface 132 and the attachment flap is folded across the upper edge 131. As can be seen, parts of the bag walls have been pressed against each other, forming the attachment flap 52 and sealing off the main body 51. In FIG. 15b a gutter element 3 has been positioned over the attachment flap 52 and is thus carried the upper edge of the first side wall 13, thereby attaching the paper bag 5 to the first side wall 13.
