Definitions

  • the present disclosure relates to cartridges for preparing liquid products.
  • Various embodiments may refer to cartridges for preparing beverages, for example coffee.
  • Cartridges for preparing liquid products, such as a beverage, via introduction, into the cartridge, of liquid (possibly under pressure and/or at a high temperature) and/or steam constitute a technological sector that is extremely rich and articulated, as documented, for example, by FR-A-757 358, FR-A-2 373 999 (corresponding to which is U.S. Pat. No. 4,136,202), FR-A-2 556 323, GB-A-938 617, GB-A-2 023 086, CH-A-406 561, U.S. Pat. No. 3,403,617, U.S. Pat. No. 3,470,812, U.S. Pat. No.
  • a fair share of the solutions described in the documents referred to above primarily regards preparation of liquid products constituted by beverages such as coffee, tea, chocolate, broth, soups, or various infusions.
  • EP-A-0 507 905 describes a cartridge that is to be perforated by filtering tips as a result of the pressure of the liquid and/or steam introduced into the cartridge.
  • a solution of this type may be used, for example, for producing cartridges or capsules of a perforable type, in which:
  • Solutions of the above type are particularly suited for dispensing beverages of an espresso-coffee type.
  • WO 2010/106516 A1 describes a type of cartridge such as to combine a filter paper and a biopolymer, the filter paper being positioned on the side of the outlet for the beverage (coffee).
  • WO 2012/077066 A1 describes a cartridge in which the perforation is aided by the combination of a biodegradable/compostable polymer with material such as paper.
  • WO 2010/137952 A1 a cartridge or capsule is described configured for functioning in a machine (originally designed to function with a cartridge of a different type) provided with tips that are designed to tear the cartridge upon mechanical closing of the assembly for enabling entry of water into the cartridge through the tears made.
  • the cartridge according to the solution described in WO 2010/137952 A1 is configured so as to not to interact with the perforating tips of the machine in so far as the tips in question do not touch the bottom of the cartridge.
  • One or more embodiments may refer to cartridges of the type described in WO 2014/097039 A1.
  • the object of the various embodiments is to provide further improvements over the solutions referred to above, for example as regards the possibility of preparing liquid products starting from a number of substances and/or the possibility of using in succession one and the same machine for preparing different liquid products, reducing any possible effects of cross-contamination.
  • Various embodiments may also regard an assortment of cartridges with differentiated characteristics.
  • FIG. 1 is a general perspective view of a cartridge according to embodiments
  • FIG. 2 is a perspective view from beneath of embodiments
  • FIG. 3 is a cross-sectional view according to the line III-III of FIG. 2 , reproduced at an enlarged scale;
  • FIG. 4 illustrates, at a further enlarged scale, the portion of FIG. 3 indicated by the arrow IV.
  • the reference number 10 designates as a whole a cartridge (or pod, or capsule, these terms being used herein as being equivalent) for the preparation of a liquid product via introduction of liquid and/or steam into the cartridge.
  • the cartridge 10 may contain a filling or dose 12 (represented schematically with dashed lines just in FIG. 3 ) of a substance or ingredient for the preparation of a liquid product such as a beverage, chosen, for example, from: toasted and ground coffee, leaf tea, powdered or soluble milk, soluble coffee, soluble chocolate, soluble barley, sugar, soluble powdered flavourings, and combinations thereof.
  • a filling or dose 12 represented schematically with dashed lines just in FIG. 3
  • a substance or ingredient for the preparation of a liquid product such as a beverage, chosen, for example, from: toasted and ground coffee, leaf tea, powdered or soluble milk, soluble coffee, soluble chocolate, soluble barley, sugar, soluble powdered flavourings, and combinations thereof.
  • the liquid product in question may be obtained by introducing into the cartridge liquid and/or steam under pressure and at high temperature (i.e., hot).
  • the cartridge 10 may contain, as exemplified in what follows:
  • the structure of the cartridge 10 which may be shaped like a tray or small cup within which the substances S 1 and S 2 are present, it is possible to distinguish:
  • the sealing foil 16 is suited to being sealingly connected, for example by heat-sealing, to the side wall 140 of the casing 14 of the cartridge, for example at a flange 144 that surrounds the mouth part of the casing 14 .
  • the casing 14 may have a tray-like conformation diverging from the bottom wall 142 to the end closed by the sealing foil 16 .
  • the diverging conformation may be a frustoconical conformation. This conformation is not on the other hand imperative in so far as the cartridge 14 may present as a whole different shapes, for example prismatic, frustopyramidal, square, etc.
  • the bottom 142 can present a sculptured structure, i.e., with alternating parts in relief and recessed, for example according to the criteria illustrated in WO 2014/097039 A1 (already cited previously), to which the reader is referred for a more detailed description.
  • the bottom wall 142 through which the liquid product is able to flow out of the cartridge 10 may present, when viewed from outside the cartridge 10 , a protruding central portion 1420 .
  • the bottom part 142 may likewise present one or more openings 1428 to enable exit of the liquid product (e.g., a beverage) formed in the cartridge 10 .
  • the liquid product e.g., a beverage
  • the aforesaid at least one opening 1428 is provided in the protruding central portion 1420 of the bottom wall 142 .
  • openings 1428 located both in the central portion 1420 and in the areas of the bottom wall that surround it (e.g., one or more of the annular cavities/ribbings of the sculptured conformation of the bottom wall 142 ).
  • the bottom wall 142 may present, if viewed from inside the cartridge 10 , a surface that is as a whole planar (at least in the aforesaid central portion 1420 ), with the consequent possibility of applying on said planar surface a lamina (e.g., a disk) 180 comprising filtering material, such as filter paper or nonwoven fabric.
  • a lamina e.g., a disk
  • the filter element 180 can thus divide the internal volume of the cartridge 10 into:
  • a “secondary” chamber located in the central portion 1420 , which may receive a certain amount of the substance S 2 .
  • the opening or openings 1428 may be made in the form of pervious through holes. Conservation of the aroma and, in general, of the organoleptic qualities of the substances S 1 and S 2 can hence be favoured by inserting the cartridge 10 in a sealed sachet (for example, of the flow-pack type), which can be opened by the user for taking out the cartridge 10 to be used.
  • a sealed sachet for example, of the flow-pack type
  • the filter element 180 may comprise a radially outer portion applied at the openings 1428 , which are possibly provided in the part of the bottom wall 142 that surrounds the central portion 1420 .
  • a further filter element 182 (e.g., including filter paper or nonwoven fabric) may be provided, coupled to the opening or openings 1428 provided in the protruding central portion 1420 of the bottom wall 142 .
  • the filter element 182 may be coupled to the opening or openings 1428 on the inner side of the bottom wall 142 of the cartridge 10 .
  • FIG. 4 highlights the fact that, in one or more embodiments, the outer surface of the bottom wall 142 of the cartridge 10 may come to rest on an array of tips P that may be present in certain brewing machines (according to known criteria, exemplified in various documents cited in the introductory part of the present description) in order to perforate the bottom wall of the cartridges and cause outflow of the liquid product being prepared.
  • the sculptured outer profile (i.e., presenting cavities and reliefs) of the bottom part 142 may provide annular seats that may be arranged, so to speak, “straddling” the tops of the tips P, with the tips P functioning as supporting formations that are able to support the bottom wall 142 of the cartridge 10 during preparation of the liquid product.
  • the resulting product may be a bicomponent product, for example coffee or tea with milk and/or sugar, coffee or milk with chocolate, etc., this example evidently not exhausting all the possible combinations.
  • the presence of the filter element 180 set so as to separate the receiving chambers in which the substances S 1 and S 2 are present can facilitate not only the operation of filling of the cartridge but also separation of the two substances until the end product is prepared, without on the other hand hindering the infusion process.
  • the presence of the filter element 182 may facilitate the action of contrast to exit from the cartridge 10 of the ingredients contained therein (e.g., of the substance S 2 ) through the openings 1428 provided in the protruding portion 1420 of the bottom wall 142 .
  • openings 1428 also in parts of the bottom wall 142 that surround the protruding portion 1420 and that the peripheral part of the filter element 180 can extend also over said openings can facilitate the action of contrast to exit from the cartridge 10 of the ingredients contained therein (e.g., of the substance S 1 ) through the openings 1428 that may be provided in the parts of the bottom wall 142 that surround the protruding portion 1420 .
  • the tips P may in fact subsequently be used for preparing liquid products, for example for preparing beverages in which the presence of this substance is not envisaged: consider purely by way of example the case of sugar.
  • the central portion 1420 is flush with the plane B-B′ in which the peripheral rim 1432 of the bottom wall 142 lies, i.e., it does not protrude from the casing of the cartridge 10 beyond this plane (see FIG. 3 ).
  • the central portion 1420 protrudes from the casing of the cartridge 10 beyond the plane B-B′ in which the peripheral rim 1432 lies.
  • the opening or openings 1428 for outflow of the aforesaid liquid product from the cartridge 10 is/are located only in the protruding central portion 1420 , with the bottom wall 142 that, on the other hand, around the protruding central portion, is without openings for outflow of the liquid product from the cartridge 10 .
  • the central portion 1420 is shaped like a spout for delivery of said liquid product.
  • One or more embodiments may envisage providing assortments of cartridges such as those exemplified herein, the assortment comprising cartridges 10 of two or more different types, in which the central portion 1420 protrudes from the bottom wall 142 by a different amount, for example by a first amount in a first type of cartridge, a second amount, different from the first, in a second type of cartridge, a third amount in a third type of cartridge, and so forth.
  • This difference between the cartridges of the assortment may be reflected, for example, in different levels of presence of the second substance S 2 (e.g., different levels of sugar) with respect to the first substance S 1 , possibly also according to the different nature of the first substance S 1 and/or of the second substance S 2 .
  • the second substance S 2 e.g., different levels of sugar
