Definitions

  • the present invention relates to a beverage capsule for use in a beverage preparation system to prepare a beverage by passing a fluid through the beverage capsule.
  • the present invention further relates to a use of the beverage capsule in a beverage preparation system to prepare a beverage.
  • a known beverage capsule comprises: a cup-shaped body comprising a base and a sidewall contiguous with the base, wherein the base is configured to be pierced by a draining member of the beverage preparation machine to allow draining a beverage from the beverage capsule; a lid which is typically sealed to the cup-shaped body, the lid and cup-shaped body enclosing an interior volume, wherein the lid is configured to be pierced by an injection member of the beverage preparation machine to inject a fluid into the beverage capsule; and a punctured support plate positioned inside the cup-shaped body and dividing the interior volume into a first compartment delimited in part by the lid and configured for holding one or more beverage ingredients and a second compartment delimited in part by the base, wherein the punctured support plate is located at a distance from said base which is equal or larger than a piercing height of the draining member of the beverage preparation machine and wherein said beverage is able to pass through the punctured support plate.
  • Such a beverage capsule is known from WO 2013/39585 A1 where a filter paper is attached to the plastic punctured support plate.
  • the paper filter in the capsule disclosed in WO 2013/39585 A1 is configured to filter the beverage made by passing the water through the beverage ingredients contained in the capsule.
  • the filter paper retains at least most of the beverage ingredients inside the capsule which, if these were to come out together with the beverage, would reduce the quality of the latter.
  • the role of the punctured support plate is avoiding that the filter paper gets damaged by the ingredients and/or the piercing member of the beverage preparation machine.
  • beverage ingredients are known. These may be divided roughly into two classes, namely extraction or infusion ingredients and dissolving ingredients.
  • the beverage capsule according to the present invention may be applied in both cases, i.e. either in the case in which the capsule is of the type which contains beverage ingredients intended to allow the beverage to be made by extraction or infusion (such as roasted ground coffee or tea leaves as with the capsule disclosed in WO 2013/39585 A1 ) and in the case in which the capsule is of the type which contains beverage ingredients intended to allow the beverage to be made following complete or partial dissolving of the beverage ingredients when the water passes through it (for example milk, chocolate, powdered tea, instant drink, etc.).
  • the known beverage capsules are used in a beverage preparation system where fluid (usually water) is supplied directly into the capsule. More specifically, the capsule is inserted in an openable and closable chamber, defined inside the beverage preparation system. When the capsule is inside the closed chamber, an injection member of the beverage preparation machine pierces the lid and water (usually hot and pressurised as required) is injected into the capsule, in order to obtain the beverage following the interaction of the water with the beverage ingredients (e.g. extraction, infusion, or partial or whole dissolution). Finally, the beverage is released from the capsule by a draining member which pierces the base allowing the beverage to flow along an outflow path of the beverage preparation system.
  • fluid usually water
  • Keurig K-Cup TM capsules have: a body that is formed from a multilayered material that includes a polyethylene or polypropylene outer layer, an ethylene vinyl alcohol copolymer (EVOH) barrier layer and a polyethylene sealing layer; a filter that is formed primarily out of paper; and a cover that is formed from a multilayered material that includes an aluminium foil outer layer, an EVOH barrier layer and a polyethylene sealing layer.
  • the filter is usually attached to and irremovable from the capsule body.
  • WO 2019/204916 A1 proposes forming the entire capsule (i.e. body, filter and cover) from a single polymeric material thus allowing recycling in a single material stream.
  • US 2017/283163 A1 proposes an aluminium capsule with a base having an elevated part to support the paper filter to avoid the use of a plastic punctured support plate.
  • metal aids in preserving the beverage ingredients which are present within the interior volume. More specifically, a known downside of polymeric materials (as in the capsule disclosed in WO 2019/204916 A1 ) is a low preservation of food ingredients inside the capsule, this is particularly caused by an insufficient oxygen tightness. The use of metal overcomes this issue.
  • the punctured support plate can perform the role of a conventional filter paper. As such, there is no longer any need to include a filter paper inside the capsule. This improves the recyclability of the capsule since there is no longer any need to separate the filter paper from the remainder of the capsule as with the capsuled disclosed in US 2017/283163 A1 .
  • the beverage capsule further comprises the one or more beverage ingredients, which ingredients are either extraction/infusion based ingredients (e.g. roasted ground coffee, tea leaves, etc.) or dissolution based (e.g. powder materials such as milk powder, chocolate powder, powdered tea, powdered soup, instant drink, etc.).
  • the beverage ingredients have a particle size distribution determined using optical microscopy according to ISO 13320:2020, wherein at least 90 volume%, and in particular at least 95 volume%, of the one or more beverage ingredients have a particle size of at least 30 ⁇ m , in particular at least 40 ⁇ m and more particularly at least 50 ⁇ m.
  • the beverage capsule according to the present invention is thus usable for preparing a variety of beverages.
  • the punctured support plate comprises openings having a size so as to prevent at least 90 volume%, in particular at least 95 volume%, and specifically at least 99 volume%, of the one or more beverage ingredients from passing therethrough. This avoids that too much of the ingredients would pass into the beverage which could otherwise negatively affect beverage quality.
  • the punctured support plate comprises openings having a smallest dimension which is at most 500 ⁇ m, in particular at most 300 ⁇ m, more in particular at most 200 ⁇ m, and most in particular at most 100 ⁇ m.
  • the smallest dimension is comprised between 50 ⁇ m and 100 ⁇ m, such as 55 ⁇ m , 60 ⁇ m, 65 ⁇ m, 70 ⁇ m, 75 ⁇ m, 80 ⁇ m, 85 ⁇ m, 90 ⁇ m or 95 ⁇ m.
  • the smallest dimension may be the diameter in case the openings are substantially circular or the width in case the openings are formed as oblong slits. Such a smallest dimension has been found to retain conventional roasted ground coffee ingredients to a sufficient extent so as to avoid these from lowering the beverage quality.
  • the punctured support plate comprises openings which are substantially uniformly distributed across the plate.
  • alternative distributions with a concentration in the center or on the outer part are also possible.
  • the distribution is mainly determined to achieve a desired contact time between the water and the beverage ingredients, which desired contact time is dependent on the type of beverage to prepare.
  • the cup-shaped body the lid and the punctured support plate are all made of a metal, preferably a food-grade metal, such as aluminium or an aluminium alloy. Ideally, all parts are made of the same metal to optimize recyclability of the capsule.
  • the cup-shaped body and the lid are both made of a metal-based laminate material comprising at least one layer of metal, the metal layer preferably comprising a food-grade metal, such as an aluminium or an aluminium alloy, wherein the punctured support plate is made of a metal, preferably a food-grade metal, such as aluminium or an aluminium alloy.
  • the metal used for the punctured support plate is the same as that used in the metal layer of the metal-based laminate. The use of the same metal in all parts optimizes recyclability of the capsule.
  • the aluminium or aluminium alloy is preferably annealed aluminium or aluminium alloy and particularly being a soft annealed aluminium or aluminium alloy.
  • the aluminium alloy may, for example, be of grade 3005, 3104, 3105, 3175, 8011 or 8079. The skilled person is familiar with these materials and their various advantages, in particular in the context of food-grade materials.
  • the metal-based laminate may comprises one or more lacquer layers (i.e. a lacquer-metal laminate).
  • a lacquer-metal laminate i.e. a heat seal lacquer, in particular a vinyl heat seal lacquer, or an epoxy stove lacquer, in particular a colored or transparent epoxy stove lacquer.
  • lacquer layers i.e. a lacquer-metal laminate.
  • a heat seal lacquer in particular a vinyl heat seal lacquer
  • an epoxy stove lacquer in particular a colored or transparent epoxy stove lacquer.
  • lacquers can influence the visual look of the cup-shaped body exterior and may also be beneficial for, in a later stage of production, applying a lid to the cup-shaped body to seal the capsule.
  • the presence of one or two lacquer layers has no negative impact on the capsule recyclability as the capsule is mainly formed from a metal material.
  • the metal-based laminate may comprise one or more polymer layers (i.e. a polymer-metal laminate).
  • the one or more polymer layers may comprise a single layer of a single polymer material or multiple layers of different polymer materials. Where multiple layers of different polymer materials are used, each layer may be applied separately when forming the sheet of material that is usually the basis for forming the cup-shaped body. However, it is preferred that the multiple layers of different polymer materials are first made up into a multilayer laminated polymer film which can then be laminated onto the metal layer (e.g. the aluminium or aluminium alloy layer) by a suitable process, for example adhesive lamination.
  • the metal layer e.g. the aluminium or aluminium alloy layer
  • the polymer materials of the one or more polymer layers may comprise materials selected from the group consisting of homopolymers, copolymers and mixtures thereof.
  • a homopolymer refers to a polymer produced by the polymerization of a single monomer.
  • a copolymer refers to a polymer produced by the polymerization of two or more monomers.
  • Suitable homopolymers include polyvinyl chloride (PVC), polypropylene (PP), low density polyethylene (LDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), polytetrafluoroethylene (PTFE), polyethylene terephthalate (PET), polychloroprene, polyisobutylene, and polyamides.
  • Suitable copolymers include fluorinated ethylene propylene (FEP), ethylene propylene diene monomer (EPDM), polyamides, thermoplastic copolyesters (TPC) and olefin block copolymers (OBC). These copolymers are preferably alternating copolymers or block copolymers.
  • An alternating copolymer refers to a copolymer with regular alternating monomer units.
  • a block copolymer refers to a copolymer comprising two or more homopolymer subunits linked by covalent bonds.
  • the cup-shaped body is integrally formed (e.g. by drawing or deep drawing operations) from a sheet of material.
  • the sheet may have a thickness between 50 and 500 microns.
  • the thickness preferably being at least 60 microns, more preferably at least 70 microns and most preferably at least 80 microns.
  • the thickness preferably being at most 400 microns, more preferably at most 300 microns, even more preferably at most 200 microns, still more preferably at most 150 microns, and most preferably at most 120 microns.
  • the sheet advantageously has a thickness of about 80 to 100 microns.
  • the sidewall comprises a stepped region, the punctured support plate engaging the stepped region.
  • the sidewall comprises a first region and a second region having a different inclination with respect to a central axis of the beverage capsule, the punctured support plate engaging the sidewall where the first region and a second region are contiguous.
  • Both embodiments rely on a change in shape of the sidewall to create an abutment surface for the punctured support plate. This allows the punctured support plate to, during assembly of the capsule, rest against the abutment surface by the influence of gravity.
  • the lid Once the capsule is filled, i.e. after the beverage ingredients are placed in the capsule, the lid is sealed to the cup-shaped body. In this way, the lid traps the beverage ingredients which therefore maintain the placement of the punctured support plate, e.g. by pushing lightly against this.
  • the punctured support plate may be welded to the abutment surface (i.e. the stepped region or the region where the sidewall inclination changes). It should be appreciated that the punctured support plate may generally be welded to the sidewall without requiring an abutment surface.
  • Another way to achieve a more secure placement of the punctured support plate is to provide one or more inwardly extending protrusions facing the abutment surface (i.e. the stepped region or the region where the sidewall inclination changes). For example, during assembly of the capsule, once the punctured support plate has been placed, the sidewall of the capsule is indented in the region above the punctured support plate. In this way, the punctured support plate is trapped between the abutment surface and the protrusions.
  • said distance between the punctured support plate and the base is at least 5 mm and preferably at least 8 mm or more. Such a distance has been found to be sufficiently far away to allow the draining member of the beverage preparation machine to sufficiently pierce the base to allow a satisfactory draining of the beverage from the capsule without contacting and/or damaging the punctured support plate.
  • the beverage capsule does not contain a filter paper.
  • the beverage capsule comprises an annular rim contiguous with the sidewall, the lid being sealed to the annular rim.
  • the provision of an annular rim provides a surface on which the lid can be easily sealed.
  • the capsule is a single-use, disposable element.
