Definitions

  • the invention relates to a capsule for preparing an infusion beverage from the interaction between an infusion product and a liquid, said capsule comprising a capsule body and a lid, said capsule body and said lid being mutually connected to one another for creating a closed infusion chamber containing said infusion product.
  • beverage preparation has some advantages over those beverages prepared from a bulk infusion product. Since the capsules contain one, or maximum two single doses per capsule, the organoleptic properties of the infusion product, are better preserved. This allows the user to prepare beverages with higher quality. Also, the user must not buy such big quantities of infusion product, thus preventing the infusion product from spoiling after the expiration date.
  • the capsules, or at least the envelopes thereof are produced with materials which are oxygen and vapour tight. These materials are e.g., aluminium, plastics, or the like. This kind of materials are not environmentally friendly, and it is advisable not to dispose the capsule in the normal litter.
  • these capsules are difficult to recycle because, firstly, the users often do not bring the capsules to the corresponding recycling facilities and if they do, the different components forming the capsule need to be separated to make the correct recycling.
  • capsules made of biodegradable materials have been proposed.
  • Document EP3354596A1 discloses a capsule for preparing beverages which after use, results in a reduced environmental load.
  • the capsule comprises a capsule body and a sealing member which is connected to a laterally projecting engagement edge of the capsule body.
  • the capsule body and/or the sealing member comprises at least one barrier layer, which barrier layer is at least partly, and preferably substantially, impermeable to oxygen.
  • the capsule body preferably also comprises at least one material layer surrounding the barrier layer which completely protects the barrier layer from the atmosphere surrounding the capsule.
  • the capsule can be disposed of after use, preferably with the organic waste, following which the capsule is molecularly decomposed in a biological manner by microorganisms, and optionally after supplying activation heat and moisture (water).
  • this capsule having a double-layer structure is complicated to produce and cannot avoid the use of the material layer to provide the atmosphere protection.
  • Document EP3774595A1 discloses a capsule for preparing a beverage.
  • the capsule comprises a body made from a biodegradable material according to standard EN 13432 and comprising at least one sealing film having at least one layer made of compostable material.
  • the sealing film leads to a composite material capsule which is complicated to produce, and even more complicated to recycle.
  • Document EP3617094A1 discloses a capsule for extracting a drink.
  • the capsule comprises a hollow body defining an internal volume for receiving a product to be infused such as coffee.
  • the hollow body comprises a tubular lateral wall with a central axis, and a bottom closing a first axial end of the lateral wall.
  • the body is made of a material chosen from among polyhydroxyalcanoates, and said material optionally further comprising at least one additive.
  • biodegradability and compostability must be clearly differentiated.
  • Biodegradability is an intrinsic characteristic of materials, which are chemically degraded by the action of micro-organisms present in each environment, characterised mainly by temperature, humidity and the organisms present. Other factors may cause degradation or fragmentation of a product, but biodegradation cannot be referred to in such cases.
  • Compostability is the characteristic of a final product made of biodegradable materials, which can physically disintegrate within a predetermined period of time without any toxic effect on the environment.
  • the product is chemically degraded thanks to a controlled environment, via predetermined high temperature and humidity conditions and microorganisms expressly applied to the process.
  • the term a) industrially compostable stands for a capsule fulfilling the biodegradability requirements for packaging recoverable product through composting and biodegradation as described in EU norm EN 13432:2000. Furthermore, the norm EN 14995:2006 provides the details on the evaluation on industrial compostability.
  • the term b) home compostable or home compost stands for a capsule in which the material so defined undergoes degradation by biological processes producing carbon dioxide, water and organic compounds and biomass.
  • the term b) home compostable or home compost stands for a capsule in which the material so defined undergoes degradation by biological processes producing carbon dioxide, water and organic compounds and biomass.
  • the term home composting is applied to a capsule fulfilling the requirements of the "OK Compost Home” mark of the certifying institute TÜV Austria, as detailed in their website https://www.tuv-at.be/green-marks/certifications/ok-compost-seedling/ , according to the latest update of the site of 18 August 2021 as recorded in the Internet Archive accessible through the so-called “Wayback Machine” (www.archive.org).
  • the OK Compost Home refers to products that also compost at lower temperatures compared to industrial compost. Therefore, they can go into the compost heap in the garden at home.
  • the conditions for home compost are based on the fulfilment of 4 criteria for the product to be considered as a home compostable end product. These criteria must be verified by corresponding tests. These conditions are the following:
  • the capsule must further avoid migration of the material into the infusion product.
  • a capsule of the type indicated at the beginning characterized in that said capsule body is made of a capsule body material comprising PBS (polybutylene succinate), PBAT (polybutylene adipateterephthalate), polylactic acid (PLA), thermoplastic starch (TPS), polyhydroxyalkanoates (PHA), regenerated cellulose or combinations thereof and at least one catalysator for enhancing the biodegradability of said capsule body, said at least one catalysator comprising one among the group of polyphosphate salts, phthalates, epoxides or combinations thereof.
  • polyhydroxyalkanoate refers to biodegradable, thermoplastic aliphatic polyesters which may be produced by polymerization of the respective monomer hydroxy aliphatic acids (including dimers of the hydroxy aliphatic acids), by bacterial fermentation of starch, sugars, lipids, or the like.
  • PHA consists of one or more of: poly-beta-hydroxybutyrate (PHB) (also known as poly-3-hydroxybutyrate); poly-alpha-hydroxybutyrate (also known as poly-2-hydroxybutyrate); poly-3-hydroxypropionate; poly-3-hydroxyvalerate; poly-4-hydroxybutyrate; poly-4-hydroxyvalerate; poly-5-hydroxyvalerate; poly-3-hydroxyhexanoate; poly-4-hydroxyhexanoate; poly-6-hydroxyhexanoate; polyglycolic acid; etc., including copolymers, such as poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV); Polyhydroxybutyrate-hexanoate (PHBH); blends, mixtures, combinations, etc., of different PHA polymers.
  • PHB poly-beta-hydroxybutyrate
  • PHBH Polyhydroxybutyrate-hexanoate
  • an infusion beverage refers to any type of edible infusion prepared from a hot or cold liquid, and preferably water.
  • Infusion products according to the invention comprise infusion products such as, for example, coffee, tea, mate infusion or other beverages such as liquid chocolate, soup or even juices obtained from any product soluble in liquids such as water or the like.
  • Infusion beverages according to the invention are prepared by introducing a liquid, preferably hot water, under a pressure of between 1 and 20 bar in the capsule containing infusion product.
  • a catalysator comprising one among the group of polyphosphate salts, phthalates, epoxides or combinations thereof in the body capsule material having a base of PBS (polybutylene succinate), PBAT (polybutylene adipateterephthalate), polylactic acid (PLA), thermoplastic starch (TPS), polyhydroxyalkanoates (PHA), regenerated cellulose provides an accelerated compostability reaction after use of the capsule.
  • PBS polybutylene succinate
  • PBAT polybutylene adipateterephthalate
  • PLA polylactic acid
  • TPS thermoplastic starch
  • PHA polyhydroxyalkanoates
  • compostability is especially accelerated by adding the cited polyphosphate salts, phthalates, epoxides to the base material or blend with which the capsule body is produced.
  • These components are often used in the food industry or in the production of plastics suitable for contact with food, as plasticisers, as they reduce the glass transition temperature, increasing the flexibility and elasticity of the plastics. The higher the proportion of plasticisers, the greater the flexibility achieved.
  • the invention further includes several preferred features that are object of the dependent claims and the utility of which will be highlighted hereinafter in the detailed description of an embodiment of the invention.
  • polyphosphate salts among the preferred catalysator.
  • said polyphosphate salt is at least one among sodium polyphosphate, potassium polyphosphate or combinations thereof. It has been surprisingly found that polyphosphate salts have some advantages over other compounds when improving disintegration during the composting process. Polyphosphates are highly hydrophilic and therefore represent a good starting point for degradation of the polymeric chain. Once detached from the matrix, they provide an optimum fertilizer for the compost medium, thus surprisingly boosting the assimilation of the product by the microorganisms.
  • polyphosphates In the case of polyphosphates, they are indispensable compounds in the formulation of mineral fertilisers. Their absence limits plant growth. It is very common for phosphate-rich fertilisers to be used to induce and strengthen flowering. Phosphates are also widely used ingredients in the food industry, due to their multifunctionality, from emulsifiers, stabilisers, anti-caking agents, etc. However up to date, surprisingly no relation had been found as home compost enhancers.
  • Another problem that the invention seeks to solve is how to improve the barrier properties to oxygen and water vapour of the capsule, as well as the mechanical properties in terms of pressure withstand and resistance to temperature of extraction in the infusion beverage machine without degrading.
  • said capsule body material further comprises one or several organic fillers, the total amount of said one or several organic fillers being between 5 and 25% w/w, and one or several inorganic fillers, the total amount of said one or several inorganic fillers being between 5 and 20% w/w.
  • said capsule body material comprises between 60% to 89.5% w/w of biodegradable PBS, PBAT, PLA, TPS, PHA, regenerated cellulose or combinations thereof and between 0.5 and 5% w/w, preferably between 0.5 and 2% w/w, of said at least one catalysator.
  • said capsule body material comprises between 70% to 89.5% w/w of biodegradable PBS, PBAT, PLA, TPS, PHA, regenerated cellulose or combinations thereof.
  • biodegradable PBS, PBAT, PLA, TPS, PHA, regenerated cellulose or combinations thereof Being able to maintain a large amount of biodegradable PBS, PBAT, PLA, TPS, PHA, regenerated cellulose or combinations thereof in the composition is further advantageous to maintain the high thickness required in the capsule body to withstand the harsh pressure and temperature conditions for the beverage preparation.
  • said capsule body material comprises between 75% to 85% w/w of biodegradable PBS, PBAT, PLA, TPS, PHA, regenerated cellulose or combinations thereof.
  • said capsule body material comprises between 75% to 81.5% w/w of biodegradable PBS, PBAT, PLA, TPS, PHA, regenerated cellulose or combinations thereof.
  • the optimal synergistic effects with the fillers are obtained. This allows to maintain the high thickness required in the capsule body to withstand the harsh pressure and temperature conditions for the beverage preparation, while ensuring an optimal mechanical stability and an optimal pierceability without compromising the biodegradability and compostability of the capsule.
  • the combination of components, that is biodegradable PBS, PBAT, PLA, TPS, PHA, regenerated cellulose or combinations, with the catalysator, together with one or several organic fillers and one or several inorganic fillers, provides for a capsule which is at least industrially compostable, but at the same time offers improved barrier properties, as well as an even better resistance to pressure and temperature, thus reducing problems of deformation and breakage in use.
  • the total amount of said one or several organic fillers is between 10 and 20% w/w of said capsule body material, providing an even more optimal compromise between oxygen and vapour barrier and mechanical and thermal properties.
  • said lid is made of a sheet of lid material comprising one among cellulose covered at least with a watertight coating layer, PLA (polylactic acid), PCL (plycaprolactone), PBS (polybutylene succinate), PBAT (Polybutylene adipate terephthalate), or combinations thereof.
  • said capsule comprises a sealing member which is separated from the capsule body.
  • the separated sealing member can have different mechanical properties than the rest of the capsule and thus deform more easily than the rest of the capsule. This create an improved watertight seal between a leading sealing edge of an enclosing member configured to receive the capsule when used in a device for preparing infusion beverages.
  • the sealing member is made of a compostable material.
  • a compostable material such as a cardboard, cellulose, paper, or biopolymers such as PLA (polylactic acid), PCL (polycaprolactone), PBS (polybutylene succinate), PBAT (polybutylene adipate terephthalate), TPS (thermoplastic starch), PHA (polyhydroxyalkanoate) or the like. Thanks to the material choose, the capsule body and the sealing member can be composted without any intermediate handling or separation.
  • the sealing member is a planar, circular annular ring of a compostable material.
  • Other shapes different to circular are also conceivable, such as a polyhedron.
  • the ring is in this case planar, it could also have other cross sections such as semi-circular, triangular, saw-shaped like or the like.
  • the sealing member can be attached to the flange of the capsule body with an adhesive layer or with holding elements formed in the capsule body.
  • the capsule body 2 and the lid 4 are mutually connected to one another at the flange 18 for creating a closed infusion chamber 6, containing the infusion product 22, as shown in Figure 2 .
  • the capsule body material further comprises at least one catalysator for enhancing the biodegradability thereof.
  • the capsule body 2 is injection moulded from capsule body material indicated in the previous paragraph.
  • the capsule body 2 could also be compression moulded.
  • the capsule body 2 has wall thickness 34 which comprised between 0.3 mm and 0.8 mm.

  • the coating layer 32 diagrammatically indicated with a dashed line in Figure 1 .
  • Figures 3 and 4 show the device 100 for preparing infusions beverages comprising an enclosing member 102 configured to receive the capsule 1 and having a leading sealing edge 104, and an extraction wall 106.
  • the device 100 is configured to prepare an infusion beverage by causing the liquid to pass under pressure through the infusion chamber 6.
  • the device 100 for preparing infusion beverages has a resting position in which the leading sealing edge 104 of the enclosing member 102 is located remotely from the extraction wall 106 and an operative position in which the leading sealing edge 104 is close to the extraction wall, such that when the capsule 1 in inserted in the device, the sealing member 20 can be compressed between the sealing leading edge 104 and the extraction wall 106 to provide fluid tightness during the preparation of the infusion beverage, as detailed below.
  • the enclosing member 102 is movable towards the extraction wall 106.
  • other configurations are also possible, such as the extraction wall 106 being movable towards a static enclosing member 102 or that both parts are movable relative to each other.
  • the device 100 for preparing infusion beverages has a liquid injection pump 114 for supplying liquid to the enclosing member 102, i.e., liquid injection cylinder.
