Abstract

A packaging for a window comprising a folded sheet member and at least one fastener or bonder for interconnecting different sections of the sheet member for the formation of a box, where two lid sections are each connected to a side section of the sheet member. The sum of the widths of the lid sections is substantially equal to the width of a receiving section intended for carrying the window and the lid sections have different widths. The width of each lid section corresponds to at least ? of the width of the receiving section. Preferably, the packaging comprises an indication that it should be opened at the joint between the two lid sections and one of the lid sections preferably has a standard width regardless of the size of the packaging, preferably approximately 40 cm. A packed window and a method for packing a window is also part of the invention.

Description

(1) In the following, the invention will be described in closer detail by reference to an embodiment of the invention shown on the drawing, where:

(2) FIG. 1 shows a sheet member for a packaging according to the invention,

(3) FIG. 2 shows the packaging assembled as a box,

(4) FIG. 3 shows a first embodiment of the packaging after opening,

(5) FIG. 4 shows a second embodiment of the packaging after opening in an exploded perspective view,

(6) FIG. 5 shows a cross-section along the line A-A in FIG. 4 but not exploded,

(7) FIG. 6 shows a foam block for insertion between the window sash and a ventilation flap in a perspective view,

(8) FIG. 7 shows a foam block for protection of the handle bar in a perspective view,

(9) FIG. 8 shows another embodiment of the content in a packing in a perspective view, and

(10) FIG. 9 is a cross-section of the embodiment in FIG. 8 along the line IX-IX and corresponding to the left-hand side of FIG. 5.

(11) A sheet member 1 intended to serve as a blank for forming a packaging according to the invention is shown in FIG. 1. The sheet member comprises a receiving section 2, sides sections 3, end sections 4 and lid sections 5, the borders between which are defined by fold lines, shown as broken lines, and by cuts in the material.

(12) The sheet member 1 may be made from any appropriate material, such as corrugated cardboard of the type traditionally used for window packaging, but other materials such as plastics and composites may also be employed.

(13) In the embodiment shown, end sections 4 are provided on all of the other sections 2, 3, 5 in order to achieve a box with strong ends. This not only helps protect the window from direct impacts, but also provides stiffness, which makes the box relatively stable and well suited for being stacked.

(14) The end sections 4 are also used for the formation of the box. In this embodiment the end sections on the side sections 3 come to overlap the end sections on the receiving section 2 and are attached thereto. The overlaps are hatched on the uppermost end sections in FIG. 1 and these sections of the material may be compressed or otherwise made thinner to avoid the packaging becoming too bulky. The interconnection of the end sections, as well as all other connections mentioned herein, may be made with bonders such as tape, glue or adhesives or with fasteners such as clamps, staples, rivets or string or with any other suitable device or material.

(15) In the embodiment shown, the lid sections are made slightly over-size so that they come to overlap, when the box has been formed as shown in FIG. 2, the enlargement showing the overlap. As illustrated with the hatching in FIG. 1, one or both of the overlapping edges may be compressed, just as for the overlapping end sections explained above. Glue or an adhesive, possibly a hot-melt, may be applied on one or both of the overlapping edges to interconnect them, but it may also be sufficient to tape the joint as presently preferred.

(16) One of the lid sections is provided with a pair of cut-out ears 6, which can be pressed out and bend back for the formation of grips. These grips are then used for getting a hold on the lid section when opening the packaging. The size of the grips may vary widely but they will usually be between 25 mm and 100 mm long and between 10 mm and 40 mm wide. Presently a size of 50 mm?28 mm is preferred.

(17) Similar cut-outs 7 are made in the receiving section 2. These are intended to serve as grips for use when handling the not yet opened packaging, which may be both heavy and bulky depending on the size of the window.

(18) The use of folded-back ears as described above minimizes the risk of the user cutting his fingers on cardboard edges, but it is of course to be understood that simple recesses in the edge of the lid section or holes in the sheet member may also serve as grips.

(19) At the fold lines separating the lid sections 5 from the end sections 4 thereon the material of the sheet member has been weakened by being partially cut at an external surface of the packaging. When the user pulls upwards and outwards on the edge of the lid section 5 as indicated by the arrows P in FIG. 2, the material is torn along these lines, thus separating the lid section from the end section, which remain attached to the end section(s) on the receiving section 2 and/or side section 3.

(20) Similar weakenings may be provided between the side sections 3 and the end sections thereon in order to enable a complete collapsing of the packaging. As such weakenings may result in an increased risk of the packaging rupturing during handling or transportation it may be preferred to instead provide a tear-out strip. At present it is, however, preferred to simply rely on the user being able to tear the material at this place without the aid of weakenings. When doing this, the fold will contribute to guide the tear, but a somewhat messy separation at this place is not of big consequence.

(21) As may be seen in FIG. 3, where the torn edges are shown with a zigzag line, the now opened packaging is lying flat on the ground or floor 8. The lid section 51 and side section 31 on the left side together forms a relatively large area, which may be used as a clean and non-abrasive surface for putting down different items such as brackets, screws, flashing components etc. during mounting of the window.

(22) In this embodiment, this area is slightly longer than the sash 91 of the window 9, but not quite as wide. The difference in width is, however, not very big. Accordingly, if wishing to put down the window sash in a lying position, room can easily be made by shifting the window 9 or window frame 92 a bit to the right as shown by the arrow S.

(23) In FIG. 3, the packaging has been illustrated as having a receiving section with approximately the same dimensions as the outer dimensions of the window 9.

(24) In some cases, particularly when packing large windows, which are relatively heavy, it will however be expedient to provide strips of expanded polystyrene (EPS) or a similarly shock absorbing material around the window as shown in FIGS. 4 and 5. This has the added advantage, that the receiving section and lid sections will then be relatively larger, meaning that a larger area is available on the lid sections upon opening of the packaging.

(25) As may be seen, the window in FIG. 4 is packed not only with a lining 10, 11 of shock absorbing material along the outer sides of the frame, consisting here of both a foam member 10 and a cardboard member 11, but also with additional inserts of different sizes and shapes. At the top a cardboard box 12 containing for example covering members to be mounted on the window during installation and having substantially the same length and height as the top member of the frame have been provided as may also be seen in FIG. 5. At the bottom a smaller but similar box 13 containing for example mounting brackets and fasteners have been provided and a foam member 14 fills the remaining space, so that the entire outer surface of the bottom frame member is protected. In this way components which have to be used together with the window are supplied in the same package, substantially without increasing the total size of the box and the window is well protected from impacts and local loads.

(26) In this embodiment, additional shock absorbing material is provided for protecting the pane 93 and the opening mechanism 94, 95. The pane is protected by foam strips 15 provided on the upper surface of the pane, as is common on windows packed in cardboard boxes, and foam blocks 16, 17 are inserted between the ventilation flap 94 and the frame 91 and attached to the handle bar 95, respectively.

(27) The inserts 16, 17 used at the ventilation flap and at the handle bar may extend substantially over the entire width of the window, the inserts possibly having recesses for giving room for locking mechanisms and the like, but it is presently preferred to use block-shaped inserts as shown in FIGS. 6 and 7. As may be seen, these blocks are shaped so as to fit closely to the window, thus being able to lock onto to these and contributing to keeping the window parts in the intended mutual position during storing, handling and transportation.

(28) In FIG. 8 the window 9 has been shown without the pane so that the inserts 17 used at the handle bar are visible and in this embodiment a packaging 18 for a remote control has been added attached to the handle bar. This packaging, which also contributes to keeping the handle bar stationary during handling and transportation due to its abutment against the pane, is also shown in FIG. 9.

(29) It is of course possible to pack all windows with inserts as shown in FIGS. 4, 5, 8 and 9, but for relatively small windows the shock absorbing capability of the cardboard box is often sufficient. As an example, windows with a two layer vacuum pane 93 and having a length of less than 1 m or a total area of less than 0.9 m.sup.2 can be packed without additional shock absorbing material, while larger windows are packed with expanded polystyrene (EPS) along the frame. Windows having a length of less than 1.3 m and a total area of more than 0.9 m2 can then be packed with 15 mm EPS, windows having a length of 1.3-1.5 m with 20 mm EPS and windows longer than 1.5 m with 30 mm EPS.

(30) Traditionally, windows made with a frame consisting at least partially of polyurethane or like materials have been packed with a layer of shock absorbing material, such as EPS, all along the outer side of the frame regardless of their size. Windows made with a wooden frame have, on the other hand, been considered less sensitive and have been packed in cardboard boxes with no or only very little shock absorbing material. For window makers making windows of both types this has lead to a large number of different packaging blanks having to be kept on stock, since each window size needs two different packagings; One for the wooden windows fitting the window size and one for the other windows with room for shock absorbing material. As a consequence of the above realization, that the amount of shock absorbing material used should be depending on the size of the window, windows of the same size can now be packed using the same sheet member, regardless of the material used for the frame and sash.

(31) As mentioned above the packaging may contain components that are not part of the window as such but associated therewith, such as covering members, mounting brackets, fasteners or a remote control for operating the window once mounted. These components may be provided in boxes serving as inserts 12, 13, 18 as described above, but they may also be attached directly to the sheet member 1, preferably using a hot-melt or like adhesive. In that case they are preferably attached at the centre of the receiving section 2, where there will usually be space available underneath the pane 93 of the window as may be seen in FIGS. 5 and 8. It is presently considered particularly advantageous to attach larger components, which are likely to cause damage to painted or lacquered surface or to the pane, if they were to move around in the package during transport. One example of a component, which is advantageously attached to the sheet member is the skirt, which is typically used between the roofing material and a bottom flashing member attached to the bottom frame member of the window.

(32) It is to be understood that the invention is not limited to the embodiments shown in the drawing and explained with reference thereto. On the contrary, various modifications and combinations of the features shown will be within the scope of the invention as defined by the claims.
