[0001] The present invention relates to a packaging unit for products like eggs and similar
products like kiwis and tomatoes, for example.
[0003] Egg cases, containers or cartons known in practice are generally fabricated from
carton made of moulded pulp from paper material. Such units comprise a bottom part
provided with compartments for individual products, and a cover part that is often
hingedly connected to the bottom part. Products like eggs are transported in these
units and displayed on shelves in supermarkets, for example. Packaging units are often
provided with labels that are often made of paper provided with a print and glued
to the carton of the packaging unit. One of the problems associated with providing
a paper label with a carton is the restriction for recycling possibilities.
[0004] The present invention has for its object to obviate or at least reduce the above
stated problems with known packaging units, for example packaging units for products
like eggs, such as egg cases or egg cartons.
[0005] The present invention provides for this purpose a packaging unit according to claim
1.
[0006] By providing a packaging unit comprising a container, preferably a carton, made of
moulded pulp together with a label that is made of moulded pulp a full fibre packaging
unit is achieved. Such full fibre packaging unit can be recycled favourably. In addition,
the packaging unit according to the present invention can be provided free of addition
or chemical substances that are required for units with conventional paper labels.
This achieves a significant effect on sustainability. This effect can be improved
further by having the label shaped in the form of a rectangle such that no production
waste is created.
[0007] As a further advantage of the packaging unit according to the present invention the
freedom for designing such a packaging unit is significantly increased. So it would
be possible to present brand and/or product specific designed features possibly presenting
the brand or product identity using the embossed label for the packaging unit according
to the present invention. This provides additional possibilities in the design process.
For example, one container or carton design can be used for a range of products for
different brands as the specific design features and identifications are provided
on the label. This significantly reduces of change-overs related to the containers
or cartons such that the cost can be carried by a (large) number of products if the
designed features for which the change-over is done. Laborious adaptations to the
production process can be kept to a minimum while improving the design options for
the packaging unit.
[0008] The moulded pulp is manufactured from so-called mouldable paper relating to paper
that has been compacted in the wet phase. This compacting of the wet pulp improves
the flexibility of the label material when the paper is dried such that it can be
stretched plastically without breaking the surface of the paper. This enables the
provision of embossing on the label. For example, with a 10-20% elongation of the
fibres without breaking the surface of the label it is possible to impose an embossing
on the flat surface with a depth of about 1 mm. This enables the generation of strong
and surprising visual and optic effects, for example.
[0009] As a further advantage of a full fibre packaging unit comprising a container, such
as a carton, made of moulded pulp and a label made of moulded pulp is over all visual
appearance providing a unitary look or visual associated with the packaging unit.
Furthermore, providing the container and a label of the packaging unit according to
the present invention of similar material improves the haptic perception of someone
handling the packaging unit. In fact, someone is provided with a unitary product when
touching the product. Such tactile feedback of the unitary material packaging unit
according to the present invention to the user and/or person handling the packaging
unit provides this user and/or person with a unitary and association with sustainability.
[0010] The haptic effect described earlier that is associated with the packaging unit according
to the present invention is further enhanced by providing the label with an embossing
such that the optic effect is approved and/or the visual appearance of the packaging
unit is strengthened due to the three-dimensional effect of such embossing on a label.
[0011] As a further advantage the label optionally is printed as a matt surface combined
with a relatively soft touch. These properties are similar to the properties of the
container such that a unitary visual appearance is achieved strengthening the sustainable
effect of the packaging unit according to the present invention.
[0012] Furthermore, the combination of the container, such as a carton, and label according
to the invention further reduces any ridging effects that may occur when handling
the packaging unit.
[0013] In a presently preferred embodiment a container that is made of moulded pulp can
be made of recycled fibres. In a presently preferred embodiment the label that is
also made of moulded pulp is made of so-called virgin fibres that are better equipped
to deal with the embossing of the label.
[0014] Preferably, the embossing has a depth in the range of 0.1 - 1.5 mm, and more preferably
in a range 0.5 - 1.0 mm. Especially an embossing in the range of 0.5 - 1.0 mm has
shown an optimal visual appearance without putting too much restrictions on the manufacturing
equipment for producing the packaging units according to the present invention.
[0015] In a presently preferred embodiment of the packaging unit according to the invention
the container further comprises a cover part with a top, front and rear surface with
a label being attached to at least the top surface.
[0016] By providing a cover part the products are amongst other things protected by the
packaging units according to the present invention. By providing a label that is attached
to at least the top surface a visual and haptic effect is achieved wherein the packaging
unit remains the full fibre such that the packaging unit is a sustainable packaging
unit that can be recycled relatively easily. Preferably, the top surface of the label
also comprises an embossing. Besides the visual and haptic effect thereof, this embossing
increases the friction resistance between two packaging units according to the present
invention that are stapled on top of each other. This improves the stability of a
stack of packaging units according to the present invention. This reduces damages
to the packaging units and the products contained thereby during transport and handling
thereof.
[0017] In a presently preferred embodiment the friction coefficient of the mouldable label
is about 0.53, and above 0,45. Additional measures, such as providing an embossing,
may further increase the friction resistance.
[0018] Preferably the bottom part of the packaging unit is provided with friction resistance
increasing elements. Such elements may comprise ridges, grooves, pins, notches etcetera.
This further improves the stability of a stack of packaging units, according to the
present invention. Preferably, the friction resistance increasing elements provided
on the bottom part of the packaging unit engage the embossing that is provided on
the label provided on the cover part of the packaging unit to further improve the
stability of a stack of packaging units.
[0019] As a further advantage of providing cover part with an embossed label is that an
impact of a packaging unit that is stacked on another packaging unit will not result
in impact effects, such as indentation that significantly affects the overall visual
appearance of the packaging unit according to the present invention. Such indentation
will not change the overall appearance of the embossed label.
[0020] The shape of the embossing may also contribute to the an impact resistance. For example,
walls and elements, preferably substantially oriented in the direction of the impact
force, may improve the impact resistance.
[0021] In a presently preferred embodiment according to the present invention the label
is attached to the top surface such that air cushions are formed between the label
and the cover part.
[0022] By providing air cushions the impact resistance of the label against loads put thereon
is greatly increased. This reduces the risk of products held by the packaging unit
according to the present invention being damaged. Also, the overall visual appearances
being maintained more easily. By providing an embossing a type of relief or a topography
or engraved surface is provided such that small air rooms or air cushions are defined
between the top surface of the cover part and the label that is attached thereto.
[0023] As a further effect, the air cushions provide an insulating effect. For example,
this improves handling the container or packaging unit containing heated products.
[0024] In a presently preferred embodiment of the present invention the label of the packaging
unit is provided with a visual appearance substantially similar to that of the container.
[0025] Providing the label and container with a substantial similar visual appearance contributes
to the effect on sustainability. This visual appearance may involve roughness, hardness
etc. Preferably, the label comprises an average surface roughness between 0.1 and
100 µm, more preferably between 0.5 and 10 µm, and most preferably between 1 and 4
µm.
[0026] Preferably, the label further comprises a number of glue edges. These edges are glued
when attaching the label to the container. This assures that the edges of the label
are strongly attached to the container. In addition, this minimizes the amount of
glue that is required when attaching the label to the container. Furthermore, this
maintains the effect the air cushions may have on the impact resistance that is described
earlier. Alternatively, or in addition thereto, the contact areas of the embossing
with the container or packaging unit are glued to the container of packaging unit.
This increases the impact resistance. In addition, this contributes to an anti-ridging
effect.
[0027] In a presently preferred embodiment according to the present invention the front
surface of the bottom part of the packaging unit comprises a protrusion and the cover
part comprises a front surface provided with a corresponding opening together defining
a lock, and further the label comprises a surface provided with an embossing at the
location of the opening in the cover front surface to enhance the locking function
of the lock.
[0028] By locking the cover part and the bottom part at the front surface the packaging
unit can be closed. In a presently preferred embodiment the rear surfaces of the cover
part and the bottom part are hingedly connected. Preferably, the bottom part is provided
with a protrusion shaped as an edge or a notch, and cover part is provided with a
corresponding opening. As the protrusion fits in the opening a lock is achieved. The
protrusion can be provided directly on the bottom part or on a closing flap that is
hingedly connected to the bottom part. Optionally, the lock is kept out of sight in
the closed position due to the provision of the label over the opening, preferably
by providing in the label an embossing at the location of the opening in the cover
part. This provides an additional room or cavern for receiving the locking edge. This
is especially advantageous for a packing unit with a concealed lock. For example,
the label can be embossed with a depth of 1 mm, such that the protrusion in the bottom
part can be 1 mm larger or be manoeuvred 1 mm further into the opening in the cover
part. This enhances the locking function of the lock such that the packaging unit
according to the present invention is firmly closed. In a presently preferred embodiment
the locking edge connected to the bottom part of the packaging unit protrudes outwards
through the opening in the cover part at a slightly downward angle. This improves
the locking function.
[0029] In a further embodiment according to the invention the label further comprises a
groove through which an end of the protrusion protrudes in a closed position of the
packaging unit. This further enhances the locking function. Furthermore, extending
an and of the protrusion of the locking member slightly through the groove in the
label provides a consumer with an indication where to find the lock and how to open
the packaging unit from a closed position.
[0030] In a presently preferred embodiment according to the present invention the label
comprises an embossing with a shape such that the embossed label behaves as a stacking
element.
[0031] Often packaging units are provided with so-called denesting or stacking nocks that
function as a type of spacer maintaining a distance between individual packaging units
when they are stacked in an open position awaiting for the products to be put inside
the packaging unit, for example. The label is provided with an embossing with a shape
such that the embossed label behaves as a stacking element. For example, this shape
relates to an embossing with a sufficient depth. This may obviate the need for separate
stacking nocks or other denesting/stacking elements such that the overall design of
the packaging unit according to the present invention can be made simpler and possibly
less costly.
[0032] In a presently preferred embodiment according to the present invention the label
comprises a two-sided print.
[0033] By providing the label with a two-sided print it is possible to provide information
with both sides of the label. Therefore, the two-sided print preferably is combined
with a container having an opening that corresponds to the label print or at least
one side thereof. This achieves that one side of the label is in plain sight and the
other (back) side of the label is visible through the opening of the carton. For example,
the top surface of the label can be provided with the general markings indicating
the type of product as a branch information. The back side of the label can be provided
with specific product information that would be visible when the cover part is lifted
from the bottom part and the specific product information is made visible through
an opening provided in the cover part of the packaging unit. This prevents the need
for a separate print on the inside of the cover part of the packaging unit thereby
making the manufacturing process of such packaging unit more simple. In addition,
the manufacturing process with the method according to the invention is more cost
effective. For example, this is achieved by reducing the amount of MF material and/or
omitting the inside print on the MF material. In addition, the MF product does not
necessarily require a MF printer and can be handled on the labelling equipment.
[0034] The present invention further relates to a method for packing products comprising
the step of providing a packaging unit as described above and placing therein one
or more of the products.
[0035] Such method provides the same effects and advantages as described in respect of the
packaging unit. In fact, the method can be used on a large number of different embodiments
of the packaging unit according to the invention.
[0036] Further advantages, features and details of the invention are elucidated on the basis
of preferred embodiments thereof, wherein reference is made to the accompanying drawings,
in which:
- figure 1 shows an embodiment of the packaging unit according to the invention in a
closed position;

[0039] On the inside of bottom part 4 (Figure 5) product receiving compartments 40 are provided
having contours matching at least partially the outer contours of products, like eggs,
kiwis and tomatoes, for example. Support cones 42 are provided to add stability and
strength to packaging unit 2.
[0040] In the illustrated embodiment of packaging unit 2 front surfaces 6, 18 of bottom
part 4 en top part 14 are locked with lock 44 in the closed position of packaging
unit 2. In figure 6 packaging unit 2 is illustrated without label for illustrative
purposes. In the illustrated embodiment bottom part 4 is provided with front edge
46 comprising connecting end 48 connecting to the front surface. From connecting end
48 edge 46 comprises first edge part 50, which extends in a slightly inclined downwards
direction from connecting end 48. At first transition 50 second edge part 52 starts
to extend in a downward direction at an increased angle as compared to first edge
part 50. Second transition 54 connects second edge part 52 to free end 56 of locking
edge 46.
[0041] In the illustrated closed position of packaging unit 2 (Figure 5) free end 56 extends
through opening 58 in front surface 18 of cover part 14 into hollow part or cavern
60 at the location of the inside of a peak 34 of embossing 32 provided in label 26.
[0042] In the illustrated embodiment (Figure 5), in the closed position, connecting end
48 is preferably positioned above opening 58 and first transition 50 preferably engages
the upper edge of opening 58. Furthermore, in the illustrated embodiment locking edge
46 protrudes outwardly through opening 50 at a slightly downward angle to increase
the locking function. It will be understood that according to the invention other
locks may also be applied, preferably using the hollow embossing part 60 for receiving
a locking part. In the illustrated embodiment this results in a concealed lock 44.
Lock 44 enhances the locking friction as the edge, protrusion or projection can be
dimensioned larger or can be pushed further into opening in a closed position of packaging
unit 2 as compared to conventional packaging units with flat labels.
[0043] Alternative packaging units 62, 94 (figures 7, 8 and 9) are provided with an alternative
lock 64. Lock 64 comprises first edge part 66 that is connected to edge 68 of front
surface 70 of bottom part 72. In the illustrated embodiment first edge part 66 extends
in a slightly inclined downwards direction from edge 68. At first transition 74 second
edge part 76 starts to extend in a downward direction at an increased angle as compared
to first edge part 66. In the illustrated embodiment (figure 7) there is provided
second transition 78 that connects second edge part 80 to free end 82 that protrudes
through groove or slit 84 in label 86 of cover part 88 of locking edge 46. In the
illustrated embodiment two grooves 84 (figure 8) are provided. Preferably, free end
82 only slightly protrudes through groove 84 (figure 8), for example 1 mm. In the
illustrated embodiment second edge part 76 extends through opening 90 in cover part
88 into cavern or room 92 in label 86. Free end 82 extends through groove 84. This
improves the locking function. In addition, free end 82 extending through groove 84
provides an indication to a consumer of where to find lock 64 for opening packaging
unit 62. Free end 82 may extend, in first alternative embodiment 62, through label
86 as a protruding part (figure 7). In a second presently preferred embodiment 94,
free end 82 also (slightly) extends through the label material, however, in this second
alternative embodiment 94 free end 82 remains in a recessed part 96 of label 86 (figures
8, 9) as illustrated with groove or opening 84 (figure 8). Free end 82 may be provided
at an angle with the second edge part to improve the locking function, for example
similar to the first alternative embodiment 62, and/or with an additional edge (not
shown) on free end 82.
[0044] In the illustrated embodiment, the cover part is provided with an optional window
opening (not shown) through which the back side of the label is visible. This back
side of the label is optionally provided with text and/or images.
[0045] The weight of the label material in a presently preferred embodiment is in the range
of 90-200 g/m
2, preferably about 120-150 g/m
2. This maintains a relatively low weight of the entire packaging unit according to
the present invention. In addition, when applied to a container, such as a carton,
having a bottom and a cover part, especially the cover part can be provided with small
dimensions, more specifically having a reduced thickness thereof, such that the overall
weight of the packaging unit according to the present invention is maintained or even
slightly reduced.
[0046] Alternative packaging units according to the invention may hold other products, like
a hamburger, salad etc.
[0047] When packing products like kiwi's, eggs etc. the products are placed in compartments
40. In the illustrated embodiment cover part 14 is closed and engages bottom part
4. Lock 44 locks packaging unit 2. In the illustrated embodiment, when locking packaging
unit 2, free end 56 protrudes through opening 50 of front surface 18 of cover part
14 into hollow part/room or cavern 60 thereby enhancing the locking function.
