[0001] The present invention concerns a packaging, which protects objects inside the packaging
from the effects of blows and hits. The packaging is primarily intended to be used
for flat objects, such as shelves, doors etc., the appearance of which are especially
sensitive to blows and hits on edges and corners. The packaging is intended to be
made from foldable corrugated cardboard.
[0002] Objects, such as doors and shelves, for interior decoration are often manufactured
with a thin surface veneer or the like and a careful surface treatment. They are thus
very sensitive to blows and hits, especially at edges and corners, as minor damages
may make the product more or less unusable for appearance reasons. Such products must
be well protected during the handling at manufacturers, warehouses, retailers and
customers and during transportation between them. It is thus common that individual
objects are put into packagings made from corrugated cardboard and special inlays
are used to obtain protection of the edges. Folded or rolled corrugated cardboard
or other suitable material is used for this protection.
[0003] The damages which may occur on the goods are mostly caused in connection with transportation
or selling of the product. This kind of products are often produced in a greater number
of identical or together with each other belonging individual items. After being packed
up a number of items are often stacked lying upon each other. They are therefor exposed
to hits along the edges, depending upon e.g. handling with trucks and other means,
stacks which fall over and invidual items which during transportation to the end user
is dropped or exposed to blows onto edges of vehicles, door frames and the like.
[0004] Cartons for packaging of books and other articles of small thickness are disclosed
in US-A-3986608. The cartons include parallel, rectangular top and bottom walls which
are foldably interconnected by a pair of trapezoidally shaped parallel side walls.
A pair of end flaps is hingedly connected to each end of the top wall and include
an inner portion and an outer portion.
[0005] The object of the present invention is a packaging which in itself is so designed
that it protects the goods from damages of the kind mentioned above, without any further
additions such as inlays along the edges or the like. It is another object of the
invention to further simplify handling by supplying a packaging which is made from
a single blank, which essentially simplifies the wrapping.
[0006] The invention will below be described more in detail with refence to the embodiment
which is shown in the enclosed figures.
[0007] Figure 1 shows a closed packaging according to the invention.
[0008] Figure 2 is a cross-section through the packaging, at right angle to its length direction.
[0009] Figure 3 is a cross-section through a part of the packaging along its length direction.
[0010] Figure 4 shows a blank of a packaging according to the invention.
[0011] The packaging 1 shown in the figures is intended to be made from corrugated cardboard
and has a bottom 3, long sides 6, 7 and gables which are defined by side surfaces
9. It is a characteristic of the packaging that the long sides 6, 7 are not at right
angles to the top and bottom of the packaging but are positioned at an angle thereto
so that a cross-section of the packaging is an equally sided trapezoid as shown in
figure 2. This means that along each of the long sides the bottom 3 is a distance
"a" wider than the overall width of the top. The triangular space which is formed
along the sides is left empty. In order to obtain both a corresponding protection
against blows and a firm shape of the packaging the gable parts are made in a special
way. They include three different areas of the blank, namely closest to the bottom
3 an inner area 8 which is intended to be folded over and lay against the bottom 3,
and a side surface 9 having angular edges 13, 14 and finally an outer surface 10 which
is intended to lie against the smaller side of the packaging, formed by the two lid
parts 4, 5.
[0012] When the packaging is to be used, the item 2 of the goods is placed upon the bottom
3 and before or after that the long sides 6, 7 are folded upwards to about at right
angle to the bottom. Thereupon the short sides are folded to the position which is
shown in figure 3, whereupon the lid parts 4, 5 are folded down and the folding of
the long sides 6, 7 relative to the bottom is completed, so that the packaging takes
its desired shape. The long sides 6, 7 are then supported by the angular edges 13,
14 of the short sides and the packaging is held together, e.g. by glueing the lid
parts 4, 5 to the upper surfaces 10 of the short sides or by applying an adhesive
tape along the joining line. The packaging ought to be well adapted to the size of
the goods. The goods is the kept in its position inside the packaging by being in
contact with the side surfaces 9 and the border lines between the long sides 6, 7
and the lid parts 4, 5. There are cushioning empty spaces 11, 12 and 15 around the
edges of the packaging.
[0013] The packaging is made from corrugated cardboard and the direction of corrugation
is along the length of the packaging.
[0014] Within the frame of the inventive idea various embodiments of the packaging are possible.
It is for example possible to make the lid from one piece only and it may have an
extending flap which overlaps either one of the long sides 6, 7, whereby the packaging
may be sealed by glueing this flap to the long side. It is also possible for example
to make the packaging such that the corners next to the short sides of the triangular
space are to some extent filled up by parts of the packaging.
1. Packaging for a flat object, such as shelves, doors and the like, having the function
of protecting the enclosed object from blows and damages, where one cross-section
of the packaging is an equally sided trapezoid, characterized in that the packaging is made from corrugated board having the corrugations in the length
direction of the packaging, the trapezoid cross-section is at right angle to the length
direction of the packaging and the short sides of the packaging are retracted inside
the outer boarders of the packaging.

(9) having an angular edge (13, 14) intended to support one of the long side parts
(6, 7), characterized in that the blank is made from corrugated board having the corrugations in the length
direction of the bottom part, the short sides of the bottom part are wider than the
overall width of the one or more lid parts and each of the gable parts further includes

over and lay against the bottom part and an outer area (10) intended to lay against
the lid part/s (4, 5).
