[0001] The present invention relates to packagings, and more particularly to the support
of products in packagings and the filling of empty spaces in packagings around packaged
products.
[0002] Due to the emergence of e-commerce individual products are increasingly being sent
from a manufacturer or web shop to an end user or consumer. These products must be
packed in a transport packaging, wherein care must be taken that the product is packed
such that it will not be damaged during transport. Because speed is of great importance
during transport, packages are in practice not handled very carefully and packages
are exposed to great loads. There is therefore the risk of the transport packaging
being damaged and of the product packaged therein thereby becoming exposed. Another
risk is that under the influence of the loads the product shifts inside the packaging
and thereby makes direct contact with a wall of the packaging. Loads acting on this
wall are in that case transmitted directly to the product, which can thereby also
be damaged.
[0003] In order to reduce these risks transport packagings are usually filled with material
which holds the product for shipping clear of the walls of the packaging and which
moreover ensures that the packaging is wholly filled, whereby the walls of the packaging
are also supported. Three types of filling material are being used in practice at
this moment. Known are the plastic filling elements in different embodiments. In addition,
use is often made of air-filled bags or compartments connected into a strip. Finally,
use is still regularly made of paper or cardboard, either in the form of wads or shreds,
strips and so on.
[0004] The known filling means have different drawbacks. A recipient of a shipment cannot
for instance dispose of and process the plastic filling bodies or the plastic air-filled
bags simultaneously with the rest of the packaging, which will generally be of cardboard.
In addition, the loose plastic filling bodies are not easy to handle, either during
the filling of the packaging or during emptying thereof. The same drawback also applies
for shredded paper and paper strips. Wads of paper have the drawback that forming
paper into wads requires a relatively large number of operations and, compared to
the product for packaging, the wads are moreover often relatively large, whereby the
product cannot be fixed properly. The same problem also applies for air-filled bags
or chambers, which are also relatively large.
[0005] The invention now has for its object to provide a filling material wherein these
drawbacks do not occur, or at least do so to lesser extent.
[0006] According to the first aspect, the invention provides for this purpose a tapering
base segment and a tapering top segment connected thereto by at least one transition
zone, wherein the at least one transition zone connects a relatively narrow end of
the base segment to a relatively wide end of the top segment, and wherein the module
has a longitudinal axis running through the base segment and top segment and is relatively
easily compressible in the direction of the longitudinal axis but is relatively stiff
in a direction transversely of the longitudinal axis. By making use of a module which
can be compressed relatively easily in one direction while being relatively stiff
in a direction transversely thereof a product can be clamped and confined between
a number of such modules in a packaging. Owing to the construction of the module from
different parts the deformation thereof can be properly controlled here.
[0007] The base segment and the top segment are preferably relatively stiff in the direction
of the longitudinal axis, and the at least one transition zone is relatively easily
deformable. When the module is loaded the transition zone will thus deform while the
base segment and the top segment remain intact, whereby the behaviour of the module
is readily predictable.
[0008] When the dimensions of the base segment and the top segment substantially correspond
in the direction of the longitudinal axis, the top segment can disappear substantially
completely into the base segment when the module is compressed.
[0009] In order to guarantee a uniform and predictable deformation it is recommended that
one or more of the base segment, the at least one transition zone and the top segment
are substantially rotation-symmetrical round the longitudinal axis. The module thus
acquires in fact an - optionally stepped - truncated cone form.
[0010] The module preferably takes a thin-walled form. The stiffness of the module is on
the one hand limited, whereby the loads exerted on the product also remain limited,
while on the other the weight of the module is hereby limited.
[0011] In order to enable disposal and processing of the modules after use together with
the rest of the packaging, which will generally be manufactured from cardboard, it
is recommended that the module is manufactured from a material on cellulose basis,
in particular moulded pulp/fibre.
[0012] When a peripheral wall of the tapering base segment encloses a first angle with a
plane running transversely of the longitudinal axis and a peripheral wall of the top
segment encloses a second angle with the plane running transversely of the longitudinal
axis, and the first and second angle substantially correspond to each other, the base
segment and the top segment can display similar behaviour under load.
[0013] It is recommended in this case that the relatively narrow end of the base segment
is wider than the relatively wide end of the top segment, and the at least one transition
zone extends at least partially transversely of the longitudinal axis of the module.
The transition zone thus forms a clear discontinuity between the base segment and
the top segment which allows the deformation to proceed in controlled manner.
[0014] In order to make the module suitable for use in packagings of different dimensions
and to clamp and fix products of varying dimensions, it is recommended that a plurality
of transition zones and at least one tapering intermediate segment are arranged between
the base segment and the top segment. The module can hereby be compressed in different
steps. The different transition zones are preferably shaped and dimensioned here such
that they deform in a predetermined sequence and the module can thus be pressed into
each other in precisely controlled manner.
[0015] It is also possible to envisage that a peripheral wall of the base segment encloses
a first angle with a plane running transversely of the longitudinal axis and a peripheral
wall of the top segment encloses a second angle with the plane running transversely
of the longitudinal axis, the size of the second angle is less than half the size
of the first angle and the transition zone is substantially clear of a part extending
transversely of the longitudinal axis. Owing to the large difference in angles of
inclination there is a corresponding difference in pressure resistance between the
top segment and the base segment, whereby there is no, or less necessity for a recessed
transition zone, and the design of the module can thus be simplified.
[0016] When the base segment is configured for connection to an adjacent module, a number
of modules can be combined to form a filling and/or support element. By forming the
connection at the position of the base segments the deformation behaviour of the modules,
which is determined mainly by the top segment and the transition zone, is hereby not
affected.
[0017] The top segment is preferably closed at its relatively narrow end by an end wall.
This prevents the top segment tearing away under load, whereby controlled deformation
would no longer be possible.
[0018] According to another aspect of the invention, a filling and/or support element for
a packaging is provided which comprises a number of filling and/or support modules
of the above described type.
[0019] The modules are preferably connected to each other here in a regular pattern. The
filling and/or support element hereby has relatively uniform properties over its whole
area, whereby a product for packaging is supported in similar manner at each position
of the element. A filling and/or support element can in this way also be divided into
a number of smaller elements which can for instance be used in smaller packagings
and which will all display similar properties.
[0020] For use in rectangular packagings it is recommended that the longitudinal axes of
the modules have a substantially parallel orientation. A highly regularly shaped filling
and/or support element is thus obtained.
[0021] At least some of the modules are preferably identical. It is even possible to envisage
all modules being identical, although it is also possible to combine modules of differing
dimensions and with a different number of transition zones and/or segments with each
other in a single filling and/or support element.
[0022] According to yet another aspect, the invention provides a packaging which comprises
an outer packaging as well as two filling and/or support elements as discussed above
received therein with the top segments of the modules directed toward each other.
The outer packaging could be a cardboard box here, for instance a so-called American
folding box, which is available in different sizes.
[0023] The sum of the heights of the filling and/or support elements is here preferably
smaller than or equal to the internal height of the outer packaging. This avoids unnecessary
pressure being exerted on the packaging when the two elements are placed with their
modules on each other.
[0024] When the packaging is provided with a product received therein and clamped between
the filling and/or support elements, the sum of a maximum thickness of the product
and the dimensions of the modules of the mutually opposite filling and/or support
elements in longitudinal direction can be greater than the internal height of the
outer packaging. This guarantees that the product is clamped by deformation of the
filling and/or support modules and the outer packaging is filled over its full height
by the elements and the packaged product so that no further space remains for any
movement.
[0025] The sum of the maximum thickness of the product and the dimensions of the base segments
of the modules of the mutually opposite filling and/or support elements in longitudinal
direction is here preferably smaller than or equal to the internal height of the outer
packaging. This prevents the base segments being deformed, since such a deformation
would no longer take place in controlled manner.
[0026] In order to confine the packaged product in all directions, the maximum dimensions
of the product transversely of the thickness direction are preferably so much smaller
than those of the filling and/or support elements that at least one undeformed module
lies between the periphery of the product and each side wall of the outer packaging.
[0027] When the dimensions of each side wall of the outer packaging amount to a whole multiple
of the dimensions of a module transversely of its longitudinal axis, a filling and/or
support element can be easily cut to size from a larger whole, wherein the packaging
can be filled with whole modules.
[0028] Finally, the invention further provides a method for packaging the product. Such
a method comprises the steps according to the invention of:
- selecting a filling and/or support element as described above, the dimensions of which
are so much greater than the maximum dimensions of the product transversely of its
thickness direction that between the periphery of the product and each side edge of
the element at least one module can remain clear of the product,
- selecting an outer packaging with side walls, the dimensions of which correspond to
those of the side edges of the selected filling and/or support element,
- placing the filling and/or support element in the outer packaging such that the modules
thereof are directed toward an open side of the outer packaging,
- placing the product on the filling and/or support element such that between the periphery
of the product and each side edge of the element at least one module remains clear,
- placing on the product a second filling and/or support element, of which the top segments
of the modules are directed toward the top segments of the modules of the first element,
and
- closing the outer packaging, wherein the filling and/or support elements are moved
toward each other prior to or during the closing such that modules which make contact
with the product are compressed.
[0029] Preferably applied variants of the method are described in the dependent claim 15.

[0031] A filling and/or support module 1 for a packaging 2 comprises a tapering base segment
3 and a tapering top segment 4. Base segment 3 and top segment 4 are connected to
each other by at least one and, in the shown example, no fewer than six transition
zones 5A-5F (Fig. 1). These transition zones 5A-F connect the narrow end 6 of base
segment 3 to the wide end 7 of top segment 4. In addition to the six transition zones
5A-F, a further four intermediate segments 8A-8D are also formed between base segment
3 and top segment 4. These intermediate segments 8A-D are bounded by transition zones
5B-5F. Transition zones 5A and 5B are directly adjacent to each other without a segment
therebetween. This plurality of transition zones 5A-F and intermediate segments 8A-D
make it possible to fix products P of varying thicknesses in packaging 2, as will
be elucidated below.
[0032] Module 1 has a longitudinal axis L running through base segment 3 and top segment
4. In the direction of longitudinal axis L the module 1 is relatively easily compressible,
but in a direction transversely of longitudinal axis L the module 1 is relatively
stiff. This is achieved in the shown embodiment in that base segment 3 and top segment
4 are relatively stiff in the direction of longitudinal axis L and transition zones
5A-F are relatively easily deformable.
[0033] Base segment 3 has a wide end 9 which is remote from transition zones 5A-F and which
is open. Wide end 9 has a diameter
D (Fig.2). Formed along the outer periphery of this wide end 9 is a flange 10 which
can form part of a connection between module 1 and one or more adjacent modules. Top
segment 4 has a narrow end 11 with a diameter
d remote from transition zones 5A-F. Narrow end 11 is closed by an end wall 12. Module
1, which in the shown embodiment can be manufactured from moulded pulp (or moulded
fibre), has a substantially constant wall thickness
t.
[0034] Base segment 3 has a peripheral wall 13 and top segment 4 has a peripheral wall 14.
Both peripheral walls 13, 14 each enclose an angle α1, α2 with a plane transversely
of longitudinal axis L, for instance the plane of flange 10 or the plane of end wall
12. In the shown embodiment angles α1, α2 are substantially equal, but can also differ
greatly from each other as will be elucidated below. Intermediate segments 8A-D also
have a peripheral walls 15A-D which each enclose an angle αi with the plane transversely
of longitudinal axis L, and these angles αi can also be substantially equal to the
angles α1, α2. Angles α1, α2 and αi must in any case be acute angles in order to guarantee
that module 1 can be released from a mould in which it is formed. For the desired
controlled deformation of module 1 it is also important that angles α1, α2 and αi
are less than 90°. The greater the angles, the stiffer the associated segments will
be and the smaller the angles, the more easily the associated segments will deform
under pressure.
[0035] Module 1 has a height
h as measured in the direction of longitudinal axis L which is made up of the height
h1 of base segment 3, the height
h2 of top segment 4 and the sum of the heights of transition zones 5A-F and intermediate
segments 8A-D. The height
h1 of base segment 3 and the height
h2 of top segment 4 substantially correspond here, as will be elucidated below. The
heights of intermediate segments 8A-D are not the same, but increase from base segment
3 in the direction of top segment 4. The purpose of this variation in segment heights
is that transition zones 5A-F and intermediate segments 8A-D deform in a controlled
manner and in a predetermined sequence or collapse when module 1 is subjected to a
pressure force.
[0036] In the shown embodiment base segment 3, top segment 4 and all transition zones 5A-F
and intermediate segments 8A-D formed therebetween are rotation-symmetrical relative
to longitudinal axis L. Base segment 3, top segment 4 and intermediate segments 8A-D
thus form truncated cones, just as module 1 as a whole.
[0037] A number of modules 1 can be connected to each other to form a filling and/or support
element 16 (Fig. 3). Flanges 10 can here be connected to each other or can be connected
to a plate 17. In the shown embodiment modules 1 are received in regular rows and
columns in filling and/or support element 16, in this example with four modules 1
per row R and three modules 1 per column C. Instead of being placed adjacency of each
other, modules 1 can also be offset in adjacent rows or columns, whereby zigzag rows
or columns are formed. Modules 1 are all identical in the shown embodiment, although
it is also possible to envisage modules 1 of different shapes or dimensions being
combined in a single filling and/or support element 16. Depending on the shape and
dimensions of products P for packaging, different zones with relatively shorter and
relatively longer modules can be present in a single filling and/or support element
16 which support and fix different parts of the products.
[0038] Element 16 has side edges 18, 19 defining a length
lE and a width
bE. This length and width fit a determined size of outer packaging 22, as will be elucidated
below. Element 16 has a whole number of modules 1 in each row R and column C. This
is important because the operation of module 1 deteriorates sharply when it no longer
has a closed cross-section.
[0039] Individual modules 1 are in practice not connected to each other, but modules 1 of
filling and/or support element 16 are formed integrally from pulp of paper or cardboard.
Use can be made for this purpose of rotation machines, translation machines, or the
pulp can be processed by thermoforming. A very large number of modules 1 can be formed
here in a single operation, whereby a profiled tray 20 is created from which a plurality
of filling and/or support elements 16 can be cut. Because popular outer packagings
22, such as for instance the American folding boxes, are available in diverse sizes
(see Fig. 19A-C), it is also worthwhile making filling and/or support elements 16
available in corresponding sizes. Use can for instance be made for this purpose of
a tray 20 with dimensions corresponding to those of a so-called pallet box, i.e. 1170
x 780 mm. When for instance 48 rows and 32 columns with modules 1 are then formed
in such a tray 20, tray 20 can be repeatedly halved in the manner as known from A-sizes
in the case of paper (32 rows by 24 columns, 24 rows by 16 columns and so on). This
is shown in Fig. 18A-H, wherein the above discussed filling and/or support element
16 with four rows and three columns is shown as smallest size. Other ratios and divisions
of filling and/or support elements 16 can of course also be envisaged.
[0040] When a product P has to be accommodated in a packaging 2 and fixed therein and protected
against loads by filling and/or support elements 16 as discussed above, it is important
that elements 16 and modules 1 are chosen which are large enough to fulfil the desired
functions. Modules 1 must therefore be so high that the sum of the heights
h of the two elements 16 placed opposite each other and the thickness
dp of product P is greater than the internal height
Hi of packaging 2. It is after all only thus that modules 1 are pressed in on either
side of product P when the mutually opposite elements 16 are placed with product P
placed therebetween in packaging 2 and packaging 2 is closed (Fig. 4). Making use
of similar filling and/or support elements 16 with similar modules 1 on either side
of product P guarantees that the deformation will indeed also be distributed over
both sides of the product. The modules 1 on either side will after all display a similar
deformation under pressure.
[0041] On the other hand the sum of the thickness
dp of product P and the heights
h1 of basic segments 3 of modules 1 must be smaller than the internal height
Hi of packaging 2. This ensures that base segments 3 are not deformed when packaging
2 is closed, since such a deformation would take place in uncontrolled manner. The
only circumstance in which basic segments 3 may deform is when packaging 2 is subjected
to a high load such that it is dented locally. In that case base segments 3 may absorb
the load, whereby the packaged product P remains intact.
[0042] Both these requirements are combined in the shown embodiment in that between base
segment 3 and top segment 4 a plurality of transition zones 5A-F and intermediate
segments 8A-D are provided which, even at a relatively small height
h1 of base segment 3, nevertheless provide for a relatively great overall height
h of module 1. Base segment 3 and top segment 4 here each form about a third of the
overall height
h of module 1, while the remaining third part is taken up by transition zones 5A-F
and intermediate segments 8A-D.
[0043] It is finally recommended that the sum of the heights
h of two elements 16 placed opposite each other is smaller than the internal height
Hi of packaging 2 so that the modules 1 which play no part in clamping product P do
not contact each other either and so do not exert any unnecessary pressure on packaging
2.
[0044] Of further importance is that the length
lE and a width
bE of element 16 are so much greater than the length
lp and width
bp (as measured transversely of the thickness direction T) of the product P for packaging
that under all circumstances the product P is surrounded over its whole periphery
by a row with a width of at least one module 1. These surrounding, undeformed modules
1 thus hold product P in place transversely of its thickness direction T, while product
P is fixed in thickness direction T by the (elastic and possibly plastic) deformation
of (a part of) filling and/or support modules 1.
[0045] The form and dimensions of transition zones 5A-F and intermediate segments 8A-D are
chosen such that module 1 deforms in controlled manner under the influence of a pressure
load, such as the pressure load exerted by the product P for packaging when the packaging
is closed. In the shown embodiment this deformation proceeds in precisely determined
steps from the narrow side 6 of base segment 3 in the direction of the wide end 7
of top segment 4. In other words, the transition zone 5A adjacent to base segment
3 deforms first, followed as pressure increases by transition zone 5B. When the pressure
load increases further, third transition zone 5C also deforms, with first intermediate
segment 8A also being deformed.
[0046] The controlled pressing-in of a module 1 is shown schematically in Fig. 5-7 on the
basis of an alternative embodiment which has two transition zones 5A, 5B and a single
intermediate segment 8. Shown here is how, when a small pressure force F is exerted,
for instance by a product P for packaging, module 1 will in the first instance deform
elastically. The height of the module decreases here from
hinitial to
helastic. The material from which module 1 is manufactured will however allow only a small
measure of elastic deformation, and when the pressure force F increases further the
first transition zone 5A will deform plastically, whereby the height of module 1 decreases
to the value
hplastic_1 (Fig. 5). When further force is exerted on module 1, it will be further pressed in
in controlled manner by plastic deformation of second transition zone 5B, intermediate
segment 8 also being deformed. Top segment 4 hereby descends as it were into the wider
ring formed by base segment 3 (Fig. 6). It is recommended here that the height
h2 of top segment 4 is slightly greater than the height
h1 of the base segment so that top segment 4 continues to protrude and continues to
support product P.
[0047] Only in extreme cases, for instance when packaging 2 is exposed to a local load whereby
it is dented plastically or otherwise collapses, is it possible to envisage top segment
4 being deformed (Fig. 7). Top segment 4 can then for instance be pressed in to a
minimal height
hminimal, wherein it lies within base segment 3, but is preferably configured to nevertheless
then spring back to a height
hafter spring-back at which the narrow end 11 again protrudes above base segment 3 and further supports
product P. The deformation of top segment 4 does not proceed in controlled manner
here, and this collapsed form is therefore undesirable in principle, but does however
protect product P from damage.
[0048] As stated, the angle α1 of base segment 3, the angle α2 of top segment 4 and optionally
the angle(s) αi of intermediate segment(s) 8 can all be substantially equal as shown
in Fig. 1 and Fig. 5. Depending on the desired height of the module, the desired number
of modules per unit of area and the desired resistance of the module, these angles
α1, α2 and αi can amount to about 60-90°, preferably about 75-89°, more preferably
about 80-89°. When these angles all correspond, it is desirable for a good deformability
of transition zone 5 that it has a radial part 21 of at least 1 mm, i.e. the diameter
of the narrow end 6 of base segment 3 must be at least 2 mm larger than the diameter
of the wide end 7 of top segment 4 (Fig. 8). At lower values of the difference in
diameter module 1 with substantially parallel peripheral walls will, in the case of
the relevant type of material and wall thickness, behave under load as if no transition
zone 5 is present, and the deformation will proceed in uncontrolled manner.
[0049] When on the other hand the angle α2 of the top segment differs greatly from the angle
α1 of base segment 3, particularly when the angle α2 << α1, top segment 5 is always
less stiff than base segment 3, and an extra difference in diameter is not necessary
at the position of transition zone 5 to achieve the desired controlled deformation
behaviour. This is particularly the case when the angle of top segment 4 amounts to
less than half the angle of base segment 3 as shown in Fig. 9: α2 < 0.5. α1.
[0050] Said differences in diameter are otherwise not absolute values and they must be seen
in the light of the wall thickness
t of the different segments 3, 4, 8 and transition zone(s) 5, as well as the other
dimensions of module 1. Depending on the chosen production process, the wall thickness
t of the module will be in the order of 0.5 - 1.0 mm. Smaller thicknesses are difficult
to realize and a greater thickness results in too great a resistance to deformation,
whereby the products P for packaging may be loaded too heavily. The diameter
d of the narrow end 11 of top segment 4 will amount in practice to at least 10 mm in
order to prevent too thick an end wall 12 occurring due to material accumulation which
is too strong and can result in damage to products P. The diameter
D of the wide end 9 of base segment 3 will be in the order of 20-50 mm depending on
the chosen angles and the desired number of modules 1 in a packaging 2. The height
h of module 1 depends as stated on the internal height
Hi of the packaging 2 used and on the thickness
dp of the product P for packaging. For many used combinations of packagings 2 and products
P this height can vary between 40-70 mm.
[0051] Shown once again in Fig. 11 are the parameters which influence the deformation behaviour
of transition zone(s) 5, and thereby of module 1 as a whole. In the case of segments
which run substantially parallel the most important parameters are the difference
in diameter between the two segments 3, 4 connected by transition zone 5, the angle
at which transition zone 5 runs, the height of transition zone 5 and the rounded edges
at the position of the connection of transition zone 5 to the relevant segment 3,
4.
[0052] Fig. 10 further shows that transition zone 5 need not necessarily function as a logical
continuation of the peripheral walls of segments 3, 4, but can also be recessed.
[0053] Fig. 12A-D show different details of the connection between base or top segment 3,
4 on the one hand and transition zone 5 on the other. In addition to a sharp transition
between the different components (Fig. 12B), optionally identical rounded edges can
also be envisaged (Fig. 12C, 12D). The combination of a sharp transition and a rounded
edge can also be envisaged (Fig. 12A). The extent of rounding determines the manner
in which the pressure force F acting on module 1 is transmitted to transition zone
5 so as to there initiate the controlled deformation. The effect of different rounded
edges can be seen by comparing Fig. 13A to Fig. 13B.
[0054] In an alternative embodiment of module 1, which is not recommended at this moment,
top segment 4 is rotation-symmetrical while base segment 3 has a cross-section which
transposes from substantially round to substantially square (Fig. 14). Just as top
segment 4, transition zone 5 is here rotation-symmetrical. Base segment 3 also has
corner details 23 here, while top segment 4 is provided with a convex end wall 12.
It is thought that these design details have a favourable effect on the deformation
behaviour of module 1.
[0055] The progression of the deformation is shown in Fig. 16. After the convex end wall
12 has first been pressed in (Fig. 16B), top segment 4 is gradually pressed further
downward, wherein transition zone 5 and the part of base segment 3 adjacent thereto
deform plastically (Fig. 16C). It is also the case here that top segment 4 is in principle
not intended to deform, but can indeed do so under extreme conditions in order to
protect a product P received in packaging 2 (Fig. 16D). As further shown in Fig. 17,
modules 1 according to this embodiment are readily stackable, as is a tray formed
therefrom. This is otherwise also the case for the above discussed embodiments.
[0056] In order to make the deformation behaviour of transition zone(s) 5 and the resistance
to deformation of segments 3, 4 more readily predictable, other measures can also
be taken. Transition zone 5 can thus be provided with perforations (not shown here)
or, conversely, with reinforcements (not shown here). Peripheral walls 13, 14 of base
segment 3 and top segment 4 can further take a differing form, for instance convex,
concave or straight.
[0057] The invention thus makes it possible using means which are simple and can be manufactured
at low cost to fix products in packagings and protect them from the often rough treatment
during transport of the packaging to its end user. This using materials which originate
from recycling and which in turn can be easily refashioned for another use.
[0058] Although the invention has been elucidated above on the basis of different embodiments,
it will be apparent that it is not limited thereto but can be varied in many ways
within the scope of the following claims.
1. Filling and/or support module for a packaging, comprising a tapering base segment
and a tapering top segment connected thereto by at least one transition zone, wherein
the at least one transition zone connects a relatively narrow end of the base segment
to a relatively wide end of the top segment, and wherein the module has a longitudinal
axis running through the base segment and top segment and is relatively easily compressible
in the direction of the longitudinal axis but is relatively stiff in a direction transversely
of the longitudinal axis.
2. Filling and/or support module as claimed in claim 1, characterized in that the base segment and the top segment are relatively stiff in the direction of the
longitudinal axis, and the at least one transition zone is relatively easily deformable.
3. Filling and/or support module as claimed in claim 1 or 2,
characterized in that:
the dimensions of the base segment and the top segment substantially correspond in
the direction of the longitudinal axis; and/or
one or more of the base segment, the at least one transition zone and the top segment
are substantially rotation-symmetrical round the longitudinal axis.
4. Filling and/or support module as claimed in any of the foregoing claims, characterized in that the module takes a thin-walled form and/or the module is manufactured from a material
on cellulose basis, in particular moulded pulp/fibre.
5. Filling and/or support module as claimed in any of the foregoing claims,
characterized in that:
a peripheral wall of the tapering base segment encloses a first angle with a plane
running transversely of the longitudinal axis and a peripheral wall of the top segment
encloses a second angle with the plane running transversely of the longitudinal axis,
and the first and second angle substantially correspond to each other; and/or
the relatively narrow end of the base segment is wider than the relatively wide end
of the top segment, and the at least one transition zone extends at least partially
transversely of the longitudinal axis of the module; and/or
a plurality of transition zones and at least one tapering intermediate segment are
arranged between the base segment and the top segment.
6. Filling and/or support module as claimed in any of the claims 1-4, characterized in that a peripheral wall of the base segment encloses a first angle with a plane running
transversely of the longitudinal axis and a peripheral wall of the top segment encloses
a second angle with the plane running transversely of the longitudinal axis, the size
of the second angle is less than half the size of the first angle and the transition
zone is substantially clear of a part extending transversely of the longitudinal axis.
7. Filling and/or support module as claimed in any of the foregoing claims,
characterized in that:
the base segment is configured for connection to an adjacent module; and/or
the top segment is closed at its relatively narrow end by an end wall.
8. Filling and/or support element for a packaging, comprising a number of filling and/or
support modules as claimed in any of the foregoing claims, wherein the modules are
optionally connected to each other in a regular pattern.
9. Filling and/or support element as claimed in claim 8,
characterized in that:
the longitudinal axes of the modules have a substantially parallel orientation; and/or
at least some of the modules are substantially identical.
10. Packaging, comprising an outer packaging and two filling and/or support elements as
claimed in claim 8 or 9 received therein with the top segments of the modules directed
toward each other, wherein the sum of the heights of the filling and/or support elements
is optionally smaller than or equal to the internal height of the outer packaging.
11. Packaging as claimed in claim 10, characterized by a product received therein and clamped between the filling and/or support elements,
wherein the sum of a maximum thickness of the product and the dimensions of the modules
of the mutually opposite filling and/or support elements in longitudinal direction
is greater than the internal height of the outer packaging.
12. Packaging as claimed in claim 11,
characterized in that:
the sum of the maximum thickness of the product and the dimensions of the base segments
of the modules of the mutually opposite filling and/or support elements in longitudinal
direction is smaller than or equal to the internal height of the outer packaging;
and/or
the maximum dimensions of the product transversely of the thickness direction are
so much smaller than those of the filling and/or support elements that at least one
undeformed module lies between the periphery of the product and each side wall of
the outer packaging.
13. Packaging as claimed in any of the claims 10-12, characterized in that the dimensions of each side wall of the outer packaging amount to a whole multiple
of the dimensions of a module transversely of its longitudinal axis.
14. Method for packaging a product, comprising the steps of:
- selecting a filling and/or support element as claimed in claim 8 or 9, the dimensions
of which are so much greater than the maximum dimensions of the product transversely
of its thickness direction that between the periphery of the product and each side
edge of the element at least one module can remain clear of the product,
- selecting an outer packaging with side walls, the dimensions of which correspond
to those of the side edges of the selected filling and/or support element,
- placing the filling and/or support element in the outer packaging such that the
modules thereof are directed toward an open side of the outer packaging,
- placing the product on the filling and/or support element such that between the
periphery of the product and each side edge of the element at least one module remains
clear,
- placing on the product a second filling and/or support element, of which the top
segments of the modules are directed toward the top segments of the modules of the
first element, and
- closing the outer packaging, wherein the filling and/or support elements are moved
toward each other prior to or during the closing such that modules which make contact
with the product are compressed.
15. Method as claimed in claim 14,
characterized in that:
an outer packaging is selected, the internal height of which is smaller than the sum
of a maximum thickness of the product and the dimensions of the modules of the mutually
opposite filling and/or support elements in longitudinal direction; and/or
an outer packaging is selected, the internal height of which is greater than or equal
to the sum of a maximum thickness of the product and the dimensions of the base segments
of the modules of the mutually opposite filling and/or support elements in longitudinal
direction; and/or
an outer packaging is selected, the internal height of which is greater than or equal
to the sum of the heights of the filling and/or support elements.
