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 US-A-4 136 202), FR-A-2 556 323, GB-A-938 617, GB-A-2 023 086, CH-A-406 561, US-A-3 403 617, US-A-3 470 812, US-A-3 607 297 (corresponding to which is FR-A-1 537 031), WO- A-86/02 537, EP-A-0 199 953, EP-A-0 211 511, EP-A-0 242 556, EP-A-0 468 078, EP-A-0 469 162, EP-A-0 507 905, WO 2010
- 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:
- the top sealing foil of the cartridge (through which hot water and/or steam is introduced) is mechanically perforated by the delivery assembly via a first set of perforating tips;
- the bottom of the cartridge (through which the beverage flows out) can be perforated by a second set of hollow tips (roughly resembling injection needles) with filtering characteristics.
- Solutions of the above type are particularly suited for dispensing beverages of an espresso-coffee type .
- WO 2010/106516 Al 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) .
- This type of cartridge may be unusable in coffee machines provided with perforating tips.
- the bottom which is pre-perforated (hence already pervious), has a plane shape that may be unsuited for use in combination with particular types of filtering tips, which may alternatively:
- the document No. WO 2012/077066 Al describes a cartridge in which the perforation is aided by the combination of a biodegradable/compostable polymer with material such as paper. It has on the other hand been noted that, in particular conditions of use, the paper contained in the cartridge may be soaked with water/beverage, thus undergoing softening and hence rendering problematical its ejection from the machine in which it is used.
- Reference may again be made to the document No. WO 2010/137952 Al where 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 Al (which on the other hand does not mention the possible use of "bio” materials) 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.
- the prior art moreover comprises EP 1 579 792 Al .
- One or more embodiments may refer to cartridges of the type described in WO 2014/097039 Al .
- the object of the various embodiments is to provide further improvements over the solutions referred to above, for example as regards 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. 1 is a perspective view from beneath of embodiments ;
- FIG. 3 is a cross-sectional view according to the line III-III of Figure 2, reproduced at an enlarged scale;
- FIG. 4 illustrates, at a further enlarged scale, the portion of Figure 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 Figure 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 Figure 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 structure of the cartridge 10 which may be shaped like a tray or small cup, which contains the substance 12, there may be distinguished:
- casing 14 comprising a side wall 140 and a bottom wall 142, which closes the casing 14 at one end of the side wall 140;
- sealing foil 16 for example of a peelable type, which closes the cartridge 10 at the end opposite to the bottom wall 142.
- 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 central axis X 1 , with respect to which the casing 14 may, for example, present a (cylindrical) symmetry of rotation.
- the casing 14 may be shaped like a tray diverging from the bottom wall 142 to the end closed by the sealing foil 16.
- the diverging conformation may be frustoconical . This conformation is not on the other hand imperative in so far as the cartridge 14 may as a whole present different shapes, for example prismatic, frustopyramidal , square, etc.
- bottom 142 may present a sculptured structure, i.e., with alternating parts in relief and recessed, for example, according to the criteria illustrated in WO 2014/097039 Al (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 itself, a protruding central portion 1420, surrounded by an annular portion 1422, which, albeit possibly having the aforesaid sculptured structure, has an overall plane conformation (i.e., not shaped like a funnel or a bowl) and extends in a direction orthogonal to the central axis Xi of the casing 14.
- the bottom part 142 may present a peripheral rim 1432 substantially coplanar to the aforesaid annular portion 1422 or, as in the embodiments exemplified here, protruding from the annular portion 1422.
- the bottom part 142 may likewise present one or more openings 1428 to enable outflow of the liquid product (e.g., a beverage) formed in the cartridge 10, said opening or openings being provided, exclusively in the central portion 1420, which protrudes from the bottom wall 142.
- the liquid product e.g., a beverage
- the bottom wall 142, in the annular portion 1422 and, in general, in the portions that surround the protruding central portion 1420, may be without openings 1428 for outflow of the liquid product from the cartridge 10.
- 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 substance 12 may 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
- a filter element 182 (e.g., comprising 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 (and consequently the openings 1428) may be coupled to the distal end of the protruding portion 1420.
- the filter element 182 can be coupled to the opening or openings 1428 on the inner side of the bottom wall 142 of the cartridge 10.
- Figure 4 highlights the fact that, in one or more embodiments, the outer surface in the bottom wall 142 of the cartridge 10 may come to face an array of tips P provided in certain brewing machines (according to known criteria, exemplified in various documents cited in the introductory part of the present description) , which have the function of perforating the bottom wall of certain cartridges, different from the ones exemplified herein, and cause exit of the liquid product being prepared.
- the latter may present the peripheral rim 1432 (coplanar with respect to the annular portion 1422 or protruding therefrom) that lies in a plane B-B' (see, for example, Figure 3) .
- the central portion 1420 may protrude from the casing of the cartridge 10 beyond the plane B-B' in which the peripheral rim 1432 lies, for example by an amount denoted by d in Figure 3.
- the preparation of a liquid product with a cartridge as exemplified here may involve, according to criteria in themselves known: perforation of the top sealing foil 16 of the cartridge via a set of perforating tips of the brewing machine ;
- the protruding central portion 1420 of the bottom wall 142 may be shaped like a spout for delivery of the aforesaid liquid product.
- the presence of the filter element 182 may facilitate the action of contrast to exit from the cartridge 10 of the substance 12 through the opening or openings 1428 provided in the protruding portion 1420 of the bottom wall 142.
- the fact that, in one or more embodiments, the central portion 1420 protrudes from the casing of the cartridge beyond the plane B-B' in which the peripheral rim 1432 lies, makes it possible, together with the as a whole planar conformation in a direction orthogonal to the axis X1 (hence not shaped like a funnel or bowl) of the annular portion 1422, to keep the bottom wall 142 not in contact with the tips P, for example keeping it raised with respect to the tips P.
- the central portion 1420 which protrudes from the plane B-B', is made to extend at the centre between the tips P (which may be arranged in an annular array) so as to be able to perform its function of delivery of the liquid product through the openings 1428.
- this result can be achieved without penalizing the contents of the dose 12 thanks to the fact that the protruding central portion 1420 provides inside it an extension of the receiving chamber for the dose 12 of the substance for preparation of said liquid product.
- the fact that the liquid product can exit from the capsule 10 only through the opening or openings 1428 provided in the protruding portion 1420 of the bottom wall 142 makes it possible to limit any undesired phenomena of cross-contamination of the tips P by the substance 12 used for preparing a certain product.
- the tips P may in fact subsequently be used for preparing liquid products, for example for preparing beverages in which the presence of said substance is not envisaged: consider purely by way of example the case of sugar.
- the extension of the chamber for receiving the dose which is formed, inside the chamber, by the protruding central portion, will constitute a distinct receiving chamber with a filling consisting of a second substance for preparation of the aforesaid liquid product and that, on the bottom wall 142, there will be applied a laminar filter element (e.g., filter paper or nonwoven fabric), which separates said second receiving chamber from the rest of the internal volume of the cartridge 10.
- a laminar filter element e.g., filter paper or nonwoven fabric
- the cartridge may comprise a casing 14 having inside it a first receiving chamber with a filling of a first substance (e.g., toasted and ground coffee, leaf tea, powdered or soluble milk) for preparation of the liquid product, and a second receiving chamber with a filling of a second substance (e.g., soluble coffee, powdered milk, soluble chocolate, soluble barley, sugar, soluble powdered flavourings, and combinations thereof) that can be used together with the first substance for preparing said liquid product.
- a first substance e.g., toasted and ground coffee, leaf tea, powdered or soluble milk
- a second substance e.g., soluble coffee, powdered milk, soluble chocolate, soluble barley, sugar, soluble powdered flavourings, and combinations thereof
- 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 (and hence from the plane B - B') by a different amount d, for example by a first amount d' in a first type of cartridge, a second amount d' ' , different from the first, in a second type of cartridge, a third amount d' ' ' 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 substance 12 (represented by the greater or smaller volume of the "auxiliary" chamber defined by the internal volume of the protruding portion 1420), with the consequent possibility, for example, of preparing more or less strong beverages.
