Field of the invention
[0001] The present invention relates to a beverage capsule for preparing a beverage in a
beverage preparation machine. The present invention further relates to a method of
producing such a capsule. The present invention further relates to a use of such a
capsule in a beverage preparation machine.
Background of the invention
[0002] Capsules for beverage preparation machines are well known in the art. Capsules are
typically used for on demand dispensing of beverages like coffee, tea, hot chocolate
or the like and enjoy popularity due to their fresh tasting, variability of flavors
and the convenience of the beverage preparation.
[0003] Beverage preparation depends on a high number of parameters and effects, some of
which can be attributed to the design of the capsule.
[0004] In an eco-responsible approach, some existing capsules or pods are made of compostable
materials. For instance, documents
WO 2016/139554 A1,
WO 2020/114995 A1 disclose a compostable coffee pod. However, existing compostable capsules may not
be ideal for use in coffee machines currently on the market, which may have been originally
designed for non-compostable capsules.
[0005] It is thus an object of the present invention to provide a capsule particularly for
use in a beverage preparation machine that shall ensure high quality and beverage
consistency during preparation of the beverage. It is a further object of the present
invention to propose a capsule wherein beverage preparation ingredients can be separated
from the capsule such that the beverage preparation ingredients and the capsule can
be disposed separately from one another. It is a further object of the present invention
to propose a capsule that is fully compatible with widespread machines designed for
non-compostable capsules and provide for a proper extraction in these machines.
Solution to the problem
[0006] These and other objects, which become apparent upon reading the description, are
solved by the subject-matter of the independent claims. Further embodiments and developments
are provided in the dependent claims.
[0007] According to a first aspect of the present invention, a beverage capsule is provided.
The capsule is configured for use in a beverage preparation machine and in particular
in a capsule beverage preparation machine. The capsule is configured for preparing
a beverage upon injection of liquid into the capsule and dispensing the beverage through
the capsule. The capsule comprises a cup-shaped main body including a bottom wall
and a side wall. The capsule further comprises a sealing lid connected to the side
wall, wherein the lid, the bottom wall, and the side wall define a volume or compartment
for holding beverage preparation ingredients therein. The capsule further comprises
a scoring line extending on the lid and being configured for weakening the lid.
[0008] The capsule according to the present invention is based at least partially on the
idea that by including a scoring line extending on the lid, the lid can be weakened.
The expressions "weakening" or "weakened" may be understood as any material deficiency
or combination of deficiencies which may result in, for example, a reduced strength
of the material. For instance, and preferably, the thickness of the material in the
region of the scoring line may be reduced by at least one third. The capsule is further
based on the idea that such a weakened lid can be torn open, preferably by hand, to
gain access to the beverage preparation ingredients contained inside the capsule.
The capsule is further based on the idea that once the capsule is opened, the beverage
preparation ingredients can be removed from the opened capsule and the beverage preparation
ingredients can be disposed or composted separately from the opened capsule. If the
capsule is made of recyclable material such as a recyclable aluminum alloy material,
the opened capsule can be recycled, for example at a consumer collection station as
part of a waste disposal and recycle system. The capsule according to the present
invention proposes an eco-friendly way of using capsules in a beverage preparation
machine.
[0009] The capsule according to the present invention is particularly intended for use in
a capsule beverage preparation machine as known, for example, from
EP 0 512 470 A1 or
EP 2 919 628 A1 which are incorporated by reference herein in their entirety. Preferably, the capsule
according to the present invention is configured such that it can be used as an alternative
to known capsules typically used in such a machine.
[0010] Preferably, the scoring line is produced by means of laser scoring and/or mechanical
cutting or other suitable techniques. The scoring line may be produced prior to or
after the insertion of the beverage preparation ingredients. The scoring line may
be produced prior to or after connecting the lid to the main body. The scoring may
be produced during manufacturing of the lid.
[0011] Preferably, the lid has a substantially circular or arcuate shape and the scoring
line extends on the lid in a substantially circular or arcuate shape adapted to the
shape of the lid.
[0012] Preferably, the scoring line is such that the lid and/or capsule remains in one piece
after the capsule is opened along the scoring line.
[0013] Preferably, the scoring line extends about 360° around a central point on the lid.
Alternatively or additionally, the scoring line extends in a range between about 180°
and about 360°, preferably in a range between about 310° and about 330°, around the
central point. Alternatively or additionally, the scoring line extends 330° or less,
preferably 310° or less, around the central point of the lid. In other words, the
scoring line may extend fully around the central point or partially around the center
point.
[0014] Preferably, the scoring line extends along an external periphery of the lid, preferably
in a circumferential manner. Preferably, the scoring line extends between a central
section of the lid and a peripheral rim section of the lid attached to the capsule
body. Preferably, the peripheral rim section is attached to a flange of the side wall.
[0015] Preferably the scoring line extends on the lid in a closed curve. More preferably,
the scoring line extends on the lid in a closed and smooth curve. The expression "closed
curve" may be understood as a curve wherein the start and the end point of the curve
are connected to one another. The expression "closed and smooth curve" may be understood
that any derivatives of the curve at the start and at the end point of the curve are
equal or at least substantially equal. As an example, a scoring line extending on
the lid in the shape of an ellipse may be referred to as a closed curve. A scoring
line extending on the lid in the shape of a circle may be referred to as a closed
and smooth curve. A person skilled in the art will understand that other shapes providing
a closed or closed and smooth curve are possible.
[0016] Preferably, the scoring line extends in a peripheral rim section of the lid, the
peripheral rim section being arranged peripherally or radially outside of a central
section of the lid, the central section being configured to be pierced by a piercing
plate configured for creating a plurality of openings in the lid for dispensing the
beverage therethrough. This embodiment is based at least partially on the idea that
a capsule of the present invention may be compatible with capsule preparation machines
wherein a lid of the capsule is pierced by a piercing plate or pyramid plate for creating
a plurality of openings in the lid for dispensing the beverage therethrough. Pyramid
plates are described, for example, in
EP 0 512 470 A1. Such piercing plates typically produce a plurality of openings in a central section
of the lid. The preferred embodiment is based on the idea that if a plurality of openings
is produced in the central section of the lid, the scoring line is arranged peripherally
or radially outside of this central section. This has the effect that any creation
of openings in the lid by such a piercing plate does not interfere with the scoring
line and vice versa. In other words, the idea is to have a scoring line that extends
in a section on the lid which is peripherally or radially outside of the central section
and which remains undamaged and/or unaltered and/or does not interfere with the piercing
plate during preparation of the beverage. Capsule beverage preparation machines which
produce a plurality of openings in a central section of the lid are, for example,
capsule beverage preparation machines of the Nespresso
™ original line.
[0017] Preferably, the scoring line has a distance from an outer edge of the lid of about
5 mm or less, preferably of about 2 mm or less. This preferred embodiment is based
on the idea that a peripheral rim section of about 5 mm or less, preferably 2 mm or
less is typically outside of the aforementioned central section.
[0018] Preferably, a depth of the scoring line is in a range between about 30% and about
80%, preferably between about 50% and about 70%, of a thickness of the lid. The depth
may be measured in a direction perpendicular to an interior and/or exterior face of
the lid.
[0019] Preferably, a width of the scoring line is in a range between 100 micrometers and
500 micrometers, preferably between 200 micrometers and 300 micrometers. The width
of the scoring line may be adjustable by the machine cutting and/or laser scoring
technique used to produce the scoring line.
[0020] A width and/or a depth of the scoring line may be constant or may vary along the
scoring line, as desired.
[0021] Preferably, the capsule further comprises a grasping section for grasping at least
a portion of the lid for opening the lid along the scoring line. The grasping section
may form a pull tab.
[0022] Preferably, the grasping section is formed as an incision in the lid and/or in a
flange of the side wall.
[0023] Preferably, the flange may be configured such that the capsule can be clamped into
a capsule holder of a capsule beverage preparation machine as know, for example from
EP 0 512 470 A1 or
EP 2 919 628 A1 mentioned earlier.
[0024] Preferably, the scoring line extends onto the flange. Preferably, the scoring line
connects with the grasping section arranged on the flange. Additionally or alternatively,
the scoring line may extend onto the flange for forming the grasping section or at
least a portion thereof.
[0025] Preferably, the scoring line or portions thereof may be arranged on an interior or
internal face of the lid, the interior or internal face being a face facing the beverage
preparation ingredients inside the capsule. Preferably, only the grasping section
of the capsule may be visible from outside of the capsule.
[0026] Preferably, the scoring line is configured such that the side wall is openable manually,
preferably without using tools, more preferably by hand. Preferably, an opening of
the capsule can be assisted by grasping the grasping section and pulling on the grasping
section until the lid is torn open along the scoring line.
[0027] Preferably, the scoring line of the capsule is configured to withstand a pressure
difference between an outside and an inside of the capsule during preparation of the
beverage. Preferably, the scoring line is configured to withstand a pressure difference
of at least 4 bar, more preferably of at least 8 bar, more preferably of at least
10 bar, during preparation of the beverage. The pressure differences are typical pressure
differences used in a capsule beverage preparation machine as known, for example from
EP 0 512 470 A1 or
EP 2 919 628 A1 mentioned earlier.
[0028] Preferably, the main body has a cylindrical shape or a frustoconical shape or a domical
shape or a frustodomical shape. Preferably, the side wall has a frustoconical shape
and the bottom wall has a flat or domical shape. The shape of the main body may generally
be such that the capsule according to the present invention can be used in a capsule
beverage preparation machine as described, for example in
EP 0 512 470 A1 or
EP 2 919 628 A1.
[0029] Preferably, the capsule further comprises a coating, preferably a spray coating and/or
lacquer, that is applied over at least a segment of the scoring line. The coating
may be configured for preventing sharp edges during opening of the lid.
[0030] Preferably, the main body and/or the lid are made of a non-compostable material and/or
a recyclable material, preferably a recyclable aluminum alloy material or a polymeric
material.
[0031] The expression "compostable" may be understood as any material that complies with
certain compostability standards. For example, industrial compostability is defined
in European Norm EN 13432. Home compostability conditions are adapted based on national
standards within certain testing specifications, such as TÜV testing specifications.
Materials or products compliant with these standards can be recognized, for example,
by a conformity mark stating their home compostability. Some examples of home compostability
certifications at a national level include, but are not limited to, the following.
For example, the certifier TÜV AUSTRIA BELGIUM offers such a home compostability certification
scheme, and DIN CERTCO offers a certification for home compostability according to
the Australian standard AS 5810. Italy has a national standard for composting at ambient
temperature, UNI 11183:2006. In November 2015, the French Standard "NF T 51-800 Plastics
- Specifications for plastics suitable for home composting" was introduced. This standard
is covered in the DIN CERTCO scheme.
[0032] Another aspect of the present invention, which may form an independent aspect of

Detailed description
[0042] Within the figures, same components are referenced by the same reference numerals.
[0043] Figure 1 shows a schematic view of an example of a beverage capsule 10. The beverage capsule
10 is configured for preparing a beverage such as coffee, tea, hot chocolate, or the
like upon injecting liquid into the capsule 10. The beverage capsule 10 is particularly
suited to be used in connection with a capsule beverage preparation machine such as
described in, for example,
EP 0 512 470 A1 or
EP 2 919 628 A1. The beverage capsule 10 may be a single-serve capsule.
[0044] The capsule 10 includes a cup-shaped main body 12. The main body 12 includes a bottom
wall 14 and a side wall 16. The bottom wall 14 and the side wall 16 together form
a receptacle. The side wall 16 delimits an opening or mouth. The opening or mouth
is closed by a sealing lid 18. The sealing lid 18 is sealingly connected to the side
wall 16 such that the sealing lid 18, the side wall 16 and the bottom wall 14 together
form a compartment for holding beverage preparation ingredients therein.
[0046] The bottom wall 14 has a convex or frusto-conical shape with a central portion (not
shown), which may be generally flat, concave or convex. The bottom wall 14 is configured
to be pierced by an opener of a capsule preparation machine as described in, for example
the aforementioned
EP 2 919 628 A1.
[0047] The side wall 16 forms a flange 22 proximate to the lid 18. The flange 22 is configured
such that the capsule 10 can be clamped into a capsule holder of a capsule beverage
preparation machine as described in, for example the aforementioned
EP 2 919 628 A1.
[0048] The lid 18 is configured to be pierced by a piercing plate, such as a pyramid plate,
which is usually used in the above mentioned capsule beverage preparation machines.
The piercing plate or pyramid plate is configured for creating a plurality of openings
in the lid 18. The pyramid plate includes a plurality of reliefs and recessed (pyramid-like)
elements. These elements are configured to tear open the lid for creating a plurality
of openings in the lid under the effect of rising pressure of the liquid injected
into the capsule 10. Through these openings in the lid the beverage is dispensed.
Pyramid plates are described, for example, in
EP 0 512 470 A1.
[0049] As can be seen in
Figure 1, the capsule 10 further includes a scoring line 24. The scoring line 24 is configured
for weakening the material of the lid 18. The scoring line 24 may be produced by means
of laser scoring, mechanical cutting or another suitable technique. The scoring line
24 may be produced prior to or after the lid 18 is connected to the side wall 16.
[0050] The scoring line 24 may have a width in a range between 100 micrometers and 500 micrometers,
preferably between 200 micrometers and 300 micrometers. The width may depend on the
manufacturing technique used to produce the scoring line 24. The scoring line 24 may
have a depth in a range between about 30% and about 80%, preferably between about
50% and about 70% of a thickness of the lid 18. The scoring line 24 is designed to
weaken the lid 18 such that the lid 18 can be torn open at the position of the scoring
line 24, preferably without using tools, more preferably by hand.
[0051] In the specific embodiment shown, the scoring line 24 extends 360° around a central
point 25 of the lid 18. In other words, the scoring line 24 extends fully or in a
complete circle around the central point 25. In other embodiments, this may not be
the case. Preferably, the scoring line 24 extends on the lid 18 in a shape that is
adapted to the shape of the lid 18. In the specific embodiment shown, the shape of
the lid 18 is a generally arcuate, more precisely a circular shape and the shape of
the scoring line 24 is adapted to the circular shape.
[0052] In the specific embodiment shown, the scoring line 24 extends in a circle around
the central point 25. A circle is one example of a closed and smooth curve. A skilled
reader will understand, that in other embodiments not shown, scoring line 24 may extend
in any other suitable shape and/or curve on the lid. The shape shown in
Figure 1 shall thus not be understood as limiting the scope of the present disclosure. Preferably,
the scoring line 24 extends in a closed curve, more preferably in a closed and smooth
curve on the lid 18.
[0053] If desired, the scoring line 24 may be provided such that it does not extend around
the entire periphery of the lid 18. In this way, the lid 18 may be configured to remain
connected to the main body 12 even after opening of the lid. This may allow the consumer
to dispose of the main body 12 and the lid 18 as a single unit.
[0054] In the specific embodiment shown, the scoring line 24 extends closer to the flange
22 and/or closer to an outer edge 26 or rim 27 of the lid 18 than to the central point
25. In other words, the scoring line 24 extends in a region (distal region) that is
closer to the outer edge 26 or rim 27 than to the central point 25 of the lid 18.
In yet other words, the scoring line 24 extends in a peripherally or radially outer
section of the lid 18. The peripherally or radially outer section may also be termed
peripheral rim section of the lid 18. The scoring line 24 may have a distance from
the outer edge 26 or rim 27 of the lid 18 of about 5 mm or less, preferably 2 mm or
less.
[0055] As can be seen in
Figure 1, the flange 22 includes a grasping section 28. The grasping section 28 may assist
in opening the capsule 10, as will be explained later. The grasping section 28 may
be formed as an incision in the flange 22. The skilled reader will understand that
the grasping section 28 may be formed by any suitable means or technique. The grasping
section 28 is configured for grasping at least a portion of the lid 18 for opening
the lid 18 along the scoring line 24. In the specific embodiment shown, the scoring
line 24 does not extend to or connect with the grasping section 28. In other embodiments,
the scoring line 24 may extend to or connect with the grasping section 28.
[0056] Referring to
Figure 2, the capsule 10 of
Figure 1 is shown in a state in which the lid 18 has been pierced by a piercing plate as explained
earlier on. The piercing plate is configured for creating a plurality of openings
30 on the lid 18 for dispensing the beverage therethrough. In
Figure 2, the openings 30 are schematically indicated by rectangles. The skilled reader will
understand that any shape, number or arrangement of openings 30 may be provided on
the lid 18. Thus, the shape, number or arrangement of openings 30 shown in
Figure 2 shall not be understood as limiting the scope of the present disclosure.
[0057] As can be seen in
Figure 2, the openings 30 may be arranged in a central section of the lid 18. The scoring line
24 may be arranged peripherally outside this central section. The scoring line 24
may be arranged in a peripheral rim section. The scoring line 24 may be arranged such
that the scoring line 24 is not damaged upon producing the openings 30 by the piercing
plate. In other words, the piercing plate does not interfere with the scoring line
24. In yet other words, the scoring line 24 may be arranged in a region in which the
lid 18 remains undamaged or unaltered during piercing by the piercing plate.
[0058] Referring to
Figure 3, the capsule 10 of
Figures 2 is shown in an opened state. The capsule 10 may be opened by pulling on the grasping
section 28 formed on the flange 22. Upon pulling on the grasping section 28, the lid
18 is torn open along the scoring line 24 and the capsule 10 is opened. Opening of
the capsule 10 is done manually, preferably without using tools, more preferably by
hand. In the specific embodiment shown, the grasping section 28 remains attached to
the lid 18. In other embodiments not shown, this may not be the case. In the specific
embodiment shown, the lid 18 is detached from the main body 12 after opening of the
capsule 10. In other embodiments not shown, the lid 18 may remain attached to the
main body 12 such that the capsule 10 remains in one piece after opening.
[0059] Once the capsule 10 is opened, the beverage preparation ingredients contained inside
the capsule 10 can be removed and disposed separately from the opened capsule 10 (e.g.,
composted). The opened capsule 10 together with the lid 18 may be disposed and/or
recycled. The main body 12 and/or the lid 18 of the capsule 10 may be made of recyclable
material such as a recyclable aluminum alloy material so that the opened capsule 10
and/or the lid 18 may be recycled at a consumer collection station as part of a waste
disposal and recycle system.
[0060] Referring to
Figure 4, a schematic view of another example of a beverage capsule 32 is shown.
[0061] Capsule 32 includes cup-shaped main body 12 with bottom wall 14 and side wall 16.
An opening of the capsule 32 is closed by the sealing lid 18. The sealing lid 18,
the side wall 16 and the bottom wall 14 together form a compartment for holding beverage
preparation ingredients therein as previously described in connection with capsule
10.
[0062] The shape and size of capsule 32 may be similar to the shape and size of capsule
10. The lid 18 of capsule 32 is configured to be pierced by a piercing plate as previously
described. Thus, capsule 32 may be used, for example, in a capsule beverage preparation
machine which dispenses beverage through the lid 18. A skilled reader will understand,
however, that capsule 32 may be used in any suitable capsule beverage preparation
machine.
[0063] As can be seen in
Figure 4, capsule 32 includes a scoring line 34. The scoring line 34 extends on the lid 18.
Compared to the scoring line 24 of capsule 10, the scoring line 34 of capsule 32 does
not extend a complete or full circle around the central point 25 of the lid 18. The
scoring line 34 extends in a circle of less than 360° around the central point 25.
The scoring line 34 extends from the lid 18 onto the flange 22 and connects with the
grasping section 28. A connection portion 35 of the scoring line 34 may connect the
grasping section 28 with the circular portion of the scoring line 34. In other embodiments,
the scoring line 34 may form the grasping section 28 or at least parts of the grasping
section 28. The scoring line 34 may be produced by means of laser scoring, mechanical
cutting or another suitable technique. A width and/or depth of the scoring line 34
may be similar to a width and/or depth of the scoring line 24. The scoring line 34
is designed to weaken the lid 18 such that the lid 18 can be torn open along the scoring
line 34, preferably without using tools, more preferably by hand.
[0064] Similar to scoring line 24, scoring line 34 extends closer to the flange 22 and/or
an outer edge 26 or rim 27 of the lid 18 than to the central point 25. The scoring
line 34 extends in the peripheral rim section of the lid 18. The arcuate or circular
portion of the scoring line 34 may have a distance from the outer edge 26 or rim 27
of the lid 18 of about 5 mm or less, preferably 2 mm or less, similar to the scoring
line 24.
[0065] Referring to
Figure 5, the capsule 32 of
Figure 4 is shown in a state in which the lid 18 has been pierced by a piercing plate as explained
earlier on. As schematically indicated in
Figure 5, a plurality of openings 30 are formed on a central section of the lid 18. The scoring
line 34 is arranged peripherally outside this central section and extends in the peripheral
rim section of the lid 18. The scoring line 34 is arranged such that it remains undamaged
when the piercing plate produces the openings 30 in the lid 18.
[0066] Referring to
Figure 6, the capsule 32 of
Figures 5 is shown in an opened state. The capsule 32 may be opened by pulling on the grasping
section 28 as already explained in connection with capsule 10. Opening of the capsule
32 is done manually, preferably without using tools, more preferably by hand. In the
specific embodiment shown, the lid 18 is detached from the main body 12 after opening
of the capsule 32. In other embodiments not shown, the lid 18 may remain attached
to the capsule 32 such that the capsule 32 remains in one piece after opening.
[0067] Once the capsule 32 is opened, the beverage preparation ingredients contained inside
the capsule 10 can be removed and disposed separately from the opened capsule 32 (e.g.,
composted). The opened capsule 32 together with the lid 18 may be disposed and/or
recycled. The main body 12 and/or the lid 18 of the capsule 32 may be made of recyclable
material such as a recyclable aluminum alloy material so that the opened capsule 32
and/or the lid 18 may be recycled at a consumer collection station as part of a waste
disposal and recycle system.
[0068] A skilled reader will understand that any of the aforementioned embodiments may be
combined in any suitable way.
[0069] A skilled reader will understand that the capsules 10, 32 may include more than one
scoring line.
[0070] It should be noted that, in any of the aforementioned embodiments, the scoring line(s)
24, 34 may further be configured to withstand a pressure difference between an outside
of the capsule 10, 32 and an inside of the capsule 10, 32 that typically occur during
preparation of the beverage in the beverage preparation machine. Specifically, the
scoring line(s) 24, 34 may be configured to withstand pressure differences typically
used in capsule beverage preparation machines such as the one described in
EP 0 512 470 A1. For example, the scoring line(s) 24, 34 may be configured to withstand a pressure
difference of at least 4 bar, preferably at least 8 bar, more preferably at least
12 bar.
[0071] It should be noted that, in any of the aforementioned embodiments, the capsule 10,
32 may comprise a coating such as a spray coating or lacquer. The coating may be applied
over at least a segment of the scoring line(s) 24, 34. The coating may be used to
prevent sharp edges during opening of the capsule 10, 32 along the scoring line(s)
24.
[0072] The following aspects are preferred embodiments of the invention:
