Description

    Field of the invention
  • 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
  • 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.
  • Beverage preparation depends on a high number of parameters and effects, some of which can be attributed to the design of the capsule.
  • 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.
  • It is thus an object of the present invention to provide 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
  • 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.
  • 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 side wall and being configured for weakening the side wall and/or extending on the bottom wall and being configured for weakening the bottom wall.
  • The capsule according to the present invention is based at least partially on the idea that by including a scoring line extending on the side wall and/or the bottom wall, the side wall and/or the bottom wall 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 wall 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.

    Detailed description
  • Within the figures, same components are referenced by the same reference numerals.
  • 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.
  • 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 for holding beverage preparation ingredients. 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.
  • The main body 12 has a generally cylindrical or frusto-conical or domical or frusto-domical shape, in particular a combination of different sections of such shapes. The shape of the main body 12 may be similar to the shape described in, for example EP 2 919 628 A1 , EP 0 919 628 A1 , EP 0 512 468 A1 , EP 0 512 470 A1 , EP 1 646 305 A1 , or EP 1 165 398 A1 , all of which are incorporated by reference herein in their entirety.
  • The bottom wall 14 has a convex or frusto-conical shape with a central portion 20, 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 .
  • 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 .
  • 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 machine. The piercing plate, such as a pyramid plate, is configured for creating a plurality of openings in the lid 18. Pyramid plates include 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 .
  • As can be seen in Figure 1 , the capsule 10 further includes two scoring lines 24. The scoring lines 24 are configured for weakening the material of the main body 12. The scoring lines 24 may be produced by means of laser scoring, mechanical cutting or another suitable technique, prior to or after the capsule 10 is filled with the beverage preparation ingredients.
  • The scoring lines 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 lines 24. The scoring lines 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 side wall 16. The scoring lines 24 are designed to weaken the main body 12 such that the main body 12 can be torn open at the position of the scoring lines 24, preferably without using tools, more preferably by hand.
  • In the specific embodiment shown, the two scoring lines 24 extend in a substantially longitudinal direction of the capsule 10. In other words, the scoring lines 24 extend in a substantially perpendicular direction to the lid 18, that is in a direction from a top to a bottom of the capsule 10.
  • In the specific embodiment shown, the scoring lines 24 extend substantially parallel to one another. In other embodiments this may not be the case.
  • In the specific embodiment shown, the scoring lines 24 extend from the side wall 16 onto the bottom wall 14, e.g. up to the central portion 20 thereof. In other embodiments this may not be the case.
  • In the specific embodiment shown, the scoring lines 24 extend from the side wall 16 onto the flange 22. The scoring lines 24 extend onto the flange 22 such that a pull tap 26 is formed on the flange 22. The pull tap 26 is configured as a handle or grasping section. By applying a pulling force on the pull tap 26, the main body 12 of the capsule 10 opens along the scoring lines 24 to provide access to the beverage preparation ingredients contained inside the capsule 10.
  • Referring to Figure 2 , the capsule of Figure 1 is shown in an opened state.
  • The capsule 10 may be opened by pulling on the pull tap 26 and tearing open the capsule 10 along the scoring lines 24. The scoring lines 24 form a flap or strap 28 of material between the two scoring lines 24. Opening of the capsule 10 is done manually, preferably without using tools, more preferably by hand.
  • As can be further seen in Figure 2 , after the capsule 10 is opened, the capsule 10 remains in one piece. In the specific embodiment of Figure 2 , the scoring lines 24 are arranged such that the flap or strap 28 remains attached to the main body 12. In the specific embodiment shown, the flap or strap 28 remains attached to the main body 12 at the central portion 20 of the bottom wall 14. In other embodiments the attachment may be at a different location.
  • 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, on the other hand, may be disposed and/or recycled. The main body 12 and/or the lid of the capsule 10 may be made of recyclable material such as a recyclable aluminum alloy material so that the opened capsule 10 may be recycled at a consumer collection station as part of a waste disposal and recycle system.
  • Referring to Figure 3 , a schematic view of another example of a beverage capsule 10 is shown.
  • In the specific embodiment shown, the capsule 10 includes one scoring line 24 as compared to two scoring lines 24 shown in Figures 1 and 2 . The skilled reader will understand, that in other embodiments not shown, the side wall 16 may include more than just one scoring line 24.
  • In the specific embodiment shown, the scoring line 24 extends in a circumferential direction of the side wall 16. In other words, the scoring line 24 extends in a substantially parallel direction to the lid 18.
  • In the specific embodiment shown, the scoring line 24 is arranged at about half a distance between the lid 18 and the bottom wall 14. In other embodiments the scoring line 24 may be arranged at a different distance. The scoring line 24 divides the capsule 10 in a top section 30 and a bottom section 32. The scoring line 24 is configured to weaken the side wall 16 such that the side wall 16 can be opened along the scoring line 24.
  • In the specific embodiment shown, the capsule 10 further includes a pull tap 34 attached to a portion of the main body 12. The pull tap 34 is attached to the bottom wall 14 of the capsule 10. In other embodiments not shown, the pull tap 34 may be arranged at a different location. Preferably, the pull tap 34 is attached at the bottom section 32 of the capsule 10. The pull tap 34 may be monolithically formed with the main body 12 such that the pull tap 34 and the main body 12 are manufactured from a single piece. Alternatively, the pull tap 34 may be a separate part connected to the main body 12 by means of any suitable technique such as ultrasonic welding, heat welding or the like. The pull tap 34 is configured as a grasping section for the user of the capsule 10 to pull on the pull tap 34 for opening the capsule 10 along the scoring line 24.
  • In the specific embodiment shown, the scoring line 24 does not extend around the entire circumference of the side wall 16. Instead, the side wall 16 includes a section 36 that is unscored by the scoring line 24. This section 36 ensures that the capsule 10 remains in one piece once the capsule 10 has been opened along the scoring line 24. Section 36 may thus also be referred to as an "attachment section".
  • Referring to Figure 4 , the capsule 10 of Figure 3 is shown in an opened state.
  • The capsule 10 is opened by tearing open the side wall 16 along the scoring line 24 using, for example, the pull tap 34 arranged on the bottom section 32 of the main body 12. As can be seen, the bottom section 32 remains attached to the top section 30 by the attachment section 36. The capsule 10 remains in one piece after opening.
  • 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, on the other hand, may be disposed and/or recycled.
  • Referring to Figure 5 , a schematic view of another example of a beverage capsule 10 is shown.
  • The capsule 10 of Figure 5 is similar to the capsule 10 of Figures 3 and 4 , except that instead of a pull tap 34, the capsule 10 of Figure 5 includes a depression region 38. The depression region 38 is arranged on the main body 12, preferably at the bottom section 32. The depression region 38 is configured for handling and/or manipulating the main body 12 such that upon manipulating the main body 12, the side wall 16 is torn open along the scoring line 24. The depression region 38 may be a recess or dent formed on an exterior face of the side wall 16 extending inwardly. A size and a depth of the depression region 38 may be such that a finger or nail of a user of the capsule 10 can be comfortably accommodated inside the depression region 38. The depression region 38 may be formed during forming of the main body 12, for example during deep drawing of the main body 12.
  • Referring to Figure 6 , the capsule 10 of Figure 5 is shown in an opened state.
  • The capsule 10 is opened by tearing open the side wall 16 along the scoring line 24 using, for example, the depression region 38 arranged on the bottom section 32 of the main body 12. In the specific embodiment shown, the bottom section 32 remains attached to the top section 30 after opening of the side wall 16 by the attachment section 36. In other embodiments not shown, the bottom section 32 and the top section 30 may not be attached to one another after opening of the capsule 10.
  • 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. The opened capsule 10, on the other hand, may be disposed and/or recycled.
  • Instead of the depression region 38, a protruding region (not shown) configured to be engaged by a finger of the user could be provided. As with the depression region 38, such protruding region could be formed during deep drawing of the main body 12. As with the depression region 38, such protruding region may assist the user in tearing open the capsule 10 along the score line 24.
  • Referring to Figure 7 , a schematic view of another example of a beverage capsule 10 is shown.
  • In the capsule 10 of Figure 7 , the scoring line 24 forms a push section 40. The push section 40 is configured for pressing thereon with and/or inserting a finger or a nail of a user of the capsule 10 such that upon pushing the push section 40 in an inward direction, the side wall 16 is torn open along the scoring line 24. The push section 40 may be formed by a wave-like or arcuate section of the scoring line 24 and may indicate a position to the user for inserting the finger or nail. The push section 40 may have any suitable shape. The push section 40 may be visible from outside of the capsule 10. The push section 40 may be formed on an exterior face of the side wall 16. The remaining section or sections of the scoring line 24 may be formed on an interior face of the side wall 16. Hence, in some embodiments, only the push section 40 may be visible to a user from outside of the capsule 10. The push section 40 may be formed during production of the scoring line 24.
  • Referring to Figure 8 , the capsule 10 of Figure 7 is shown in an opened state.
  • The capsule 10 is opened by tearing open the side wall 16 along the scoring line 24, for example, by pushing in the push section 40. In other words, the scoring line 24 may tear open first along the push section 40.
