- the outer receptacle 18, and particularly the first member 32 due to the manufacturing mode, shape and size thereof, ensures support and reinforcement to the inner receptacle 12, both during the packaging and transportation steps, and during the beverage preparation cycle. Furthermore, by selecting an oxygen-impermeable material, the fragrance and preservation of the powdered ingredient can be ensured.
- the inner receptacle 12 is suitable to receive the powdered ingredient being advantageously pressed such as to ensure an optimum diffusion of the water therethrough.
- the two receptacles follow different manufacturing processes that are suitable to meet the specific requirements for which they have been conceived. At the end of the manufacturing cycle, the two receptacles are assembled with the final closure of the outer receptacle.
- the present invention further relates to a method for manufacturing a cartridge for powdered coffee or the like, which is suitable to be used in apparatus for making beverages such as coffee or the like, and described above.
- the aforesaid method comprises the steps of:
- the outer receptacle 18 is closed by means of the annular welding portion 42 between the closure membrane 34 and the edge 40 of the outer receptacle 18 and that the edge 28 of the inner receptacle 12 is at least partially rested on the edge 40 of the outer receptacle 18 in an inner portion relative to the welding annular portion 42.
- edge 28 of the inner receptacle 12 is at least partially rested to the edge 40 of the outer receptacle 18 and that the closure membrane 34 is welded or glued to the edge 40 of the outer receptacle 18 without involving the edge 28 of the inner receptacle 12.
- the edge 28 of the inner receptacle 18 only rests at the annular groove 44 of the edge 40.
- the remaining part of the edge 40 is welded to the closure membrane 34, for example by means of the annular welding portion 42.
- the cartridge according to the present invention is suitable to be used both in completely automated apparatus and in manually loaded apparatus.
- the provision of the outer receptacle ensures the fragrance and preservation of the powdered ingredient, performs a structural function of support and stiffening both during the packaging and transportation steps and when the beverage is being made.
- the provision of the inner receptacle facilitates both the production, in that it is made and closed independently of the outer receptacle, and the beverage preparation step, thereby defining an optimum water impregnation path and allowing pressing the powdered ingredient. Furthermore, it allows separate recycling as it is structurally independent of the outer receptacle and neither being glued/welded thereto, nor otherwise connected in a permanent manner.
- a further advantage of the cartridge according to the invention is the unusual structural simplicity of the latter, which allows the latter to be manufactured at a very low cost.
- the cartridge can be made such as to be pierced on the one side thereof and to be opened due to the inner pressure increase on the other side, thereby avoiding the provision of the corresponding drill punch.
- the side opening due to pressure can advantageously have weakening points in which the thickness of the material is reduced.
- the closure membrane 34 is pierced by the upper drill punch which introduces pressurized hot water within the cartridge. Due to the pressure increase inside the cartridge, the bottom 36 is opened, for example, at the weakening points, when provided.

- . Generally the lower protecting
member 60 is water-permeable for example as it is perforated or manufactured in a water-permeable material. - . In accordance with a possible embodiment, the lower protecting
member 60 is accommodated at least partially within therecess 48 obtained in the bottom 36 of theouter receptacle 18, for example rested on theribs 46, where provided. - . According to a possible embodiment, the lower protecting
member 60 has a lower cross size than the cross size of theouter receptacle 18. In this case, it is advantageously centrally arranged relative to theouter receptacle 18. - . The mode of use of the above-described cartridge will be described below.
- . The
outer receptacle 18, by being oxygen-impermeable, ensures the fragrance and the preservation of the ingredient contained therein, particularly the powdered coffee. Upon use, the cartridge can be either manually or automatically introduced inside a infusion chamber of the apparatus for making the beverage. - . When the cartridge is in place within the infusion chamber, the
closure membrane 34 and the bottom 36 of the outer receptacle are pierced, for example by means of drill punches or opened otherwise, preferably at the protecting members, when provided. Advantageously, before the upper and lower drill punches (which can be optionally provided in a number greater than one) carry out the breaking of the closure membrane and the bottom, the cartridge is subjected to a pressing action exerted by a semi-elastic member, such as to create a sealing between a lowered plane of theedge 42 and the lowerperipheral wall 47 of theouter receptacle 18. The semi-elastic member acts at a particularly resistant portion at the side wall of the outer receptacle. - . In accordance with a possible embodiment, the cartridge is first pierced at the bottom 36 and subsequently at the
closure membrane 34, for example by means of respective drill punches. The punch piercing theclosure membrane 34 consists of, for example, a nozzle through which hot pressurized water is supplied into the cartridge. The water flows through the inner receptacle, which is permeable thereto, and after it has soaked the layer of compacted powder, the beverage flows out through the opening provided in the bottom 36 of theouter receptacle 18. - . When protecting members are provided, the inner receptacle is pierced in the vicinity thereof, in order to avoid being damaged by the punch. When the upper protecting member is a sheet or film, as described above, this sheet has a greater resistance than the inner receptacle, such as to resist the piercing effect of the upper punch when it pierces the
closure membrane 34. Particularly, the upper protecting member, which is preferably made of a permeable material, is flexed under the action of the upper punch without being pierced. The provision of an upper protecting member made in the form of a sheet or film allows avoiding the formation of a chamber, thus facilitating the manufacturing process. - . After the beverage delivery is completed, the infusion chamber is opened and the cartridge is ejected, either in an automatic or manual manner.
- . The presence of a compacted layer of coffee, or generally the powdered element, ensures an optimum and even distribution of water, thus considerably improving the organoleptic characteristics of the beverage obtained.
- . In addition, the effectiveness of water infusion is further improved by the
edge 28 of theinner receptacle 12 being arranged between theedge 40 and theclosure membrane 34 of theouter receptacle 18. This arrangement, in fact, forces the whole amount of water to flow through theinner receptacle 12 thereby avoiding the formation of by-pass between theouter receptacle 18 and theinner receptacle 12. - . When
longitudinal grooves 46 are provided, this improves the flow of water/beverage to the bottom 36 of theouter receptacle 18. - . The provision of the upper and/or lower protecting members, though not strictly required, ensures the integrity of the
inner receptacle 12. - . At the end of the preparation of the beverage, the
inner receptacle 12 can be separated from theouter receptacle 18 both in a manual and automatic manner. In fact, the arrangement of theedge 28 of the inner receptacle at an area not involved with welding/gluing between theedge 40 of theouter receptacle 18 and theclosure membrane 34 maintains both receptacles structurally distinct from each other thus allowing the same to be separated after theclosure membrane 34 has been removed, for example by means of thetab 35, when provided. - . The
outer receptacle 18, and particularly thefirst member 32, due to the manufacturing mode, shape and size thereof, ensures support and reinforcement to theinner receptacle 12, both during the packaging and transportation steps, and during the beverage preparation cycle. Furthermore, by selecting an oxygen-impermeable material, the fragrance and preservation of the powdered ingredient can be ensured. - . The
inner receptacle 12 is suitable to receive the powdered ingredient being advantageously pressed such as to ensure an optimum diffusion of the water therethrough. - . The two receptacles follow different manufacturing processes that are suitable to meet the specific requirements for which they have been conceived. At the end of the manufacturing cycle, the two receptacles are assembled with the final closure of the outer receptacle.
- . In this regard, the present invention further relates to a method for manufacturing a cartridge for powdered coffee or the like, which is suitable to be used in apparatus for making beverages such as coffee or the like, and described above.
- . The aforesaid method comprises the steps of:
- . manufacturing the closed
inner receptacle 12 from a water- and oxygen-permeable material, which receptacle defines thehousing cavity 14 for thepowdered coffee 16, in which the coffee is pressed before closing theinner receptacle 12, - . inserting the
inner receptacle 12 within theouter receptacle 18, being the containment and reinforcement element of theinner receptacle 12, before closing theouter receptacle 18 thereby making the latter impermeable to water and oxygen. - . It is particularly advantageous that the
outer receptacle 18 is closed by means of theannular welding portion 42 between theclosure membrane 34 and theedge 40 of theouter receptacle 18 and that theedge 28 of theinner receptacle 12 is at least partially rested on theedge 40 of theouter receptacle 18 in an inner portion relative to the weldingannular portion 42. - . In other words, it is particularly advantageous that the
edge 28 of theinner receptacle 12 is at least partially rested to theedge 40 of theouter receptacle 18 and that theclosure membrane 34 is welded or glued to theedge 40 of theouter receptacle 18 without involving theedge 28 of theinner receptacle 12. Preferably, theedge 28 of theinner receptacle 18 only rests at theannular groove 44 of theedge 40. The remaining part of theedge 40 is welded to theclosure membrane 34, for example by means of theannular welding portion 42. - . From what has been stated above, it may be appreciated how providing a cartridge according to the present invention allows meeting the aforesaid requirement of recycling the various members composing the same in an independent manner, by separating the various materials.
- . Furthermore, the cartridge according to the present invention is suitable to be used both in completely automated apparatus and in manually loaded apparatus.
- . The provision of the outer receptacle ensures the fragrance and preservation of the powdered ingredient, performs a structural function of support and stiffening both during the packaging and transportation steps and when the beverage is being made.
- . The provision of the inner receptacle facilitates both the production, in that it is made and closed independently of the outer receptacle, and the beverage preparation step, thereby defining an optimum water impregnation path and allowing pressing the powdered ingredient. Furthermore, it allows separate recycling as it is structurally independent of the outer receptacle and neither being glued/welded thereto, nor otherwise connected in a permanent manner.
- . A further advantage of the cartridge according to the invention is the unusual structural simplicity of the latter, which allows the latter to be manufactured at a very low cost.
- . It should be understood that variations and/or additions may be provided to what has been described and illustrated above.
- . For example, the cartridge can be made such as to be pierced on the one side thereof and to be opened due to the inner pressure increase on the other side, thereby avoiding the provision of the corresponding drill punch. The side opening due to pressure can advantageously have weakening points in which the thickness of the material is reduced. In accordance with a possible embodiment, the
closure membrane 34 is pierced by the upper drill punch which introduces pressurized hot water within the cartridge. Due to the pressure increase inside the cartridge, the bottom 36 is opened, for example, at the weakening points, when provided. - . To the preferred embodiment of the cartridge as described above, those skilled in the art, aiming at satisfying contingent and specific requirements, may carry out a number of modifications, adaptations and replacements of elements with functionally equivalent ones, without however departing form the scope of the claims below.
