Abstract: A cover element for sealing capsules for use in making brewed beverages may include: a main layer having an inner surface configured to face a housing zone of a capsule for making the brewed beverages and having an outer surface that faces away from the inner surface, wherein the main layer is made of compostable material; a protective layer overlying the outer surface of the main layer; a waterproof layer, applied on the inner surface of the main layer and including at least one metallic layer; and a filtering layer underlying the inner surface of the main layer. The main layer may have a plurality of lines of weakness formed at least on the outer surface. The waterproof layer may be free of lines of weakness. The filtering layer may be free of lines of weakness.

Abstract: A method for preparing a liquid product from soluble or extractable products using a pressurized extraction fluid in a machine may include: providing a capsule that includes a container body defining a closed chamber housing the soluble or extractable products, an injection lid, a beverage dispensing lid, and a degassing valve; supplying the pressurized extraction fluid through an injection element of the machine; using the pressurized extraction fluid to force the degassing valve to remain in a closed configuration; using the pressurized extraction fluid to open the injection lid and only thereafter to enter the closed chamber; producing a beverage using the pressurized extraction fluid and the soluble or extractable products; and opening the beverage dispensing lid to release the produced beverage from the capsule. The degassing valve may include a valve body having a recess, a membrane inside the recess, and holding means to prevent loss of the membrane.

Abstract: A compostable multilayer membrane may include: a first barrier layer containing a compostable barrier film; a first metallization layer; an intermediate layer containing at least one adhesive; a second barrier layer containing a compostable barrier film; a layer adjacent to the first barrier layer, on a side opposite to the first metallization layer, the adjacent layer comprising heat-resistant lacquer; a second metallization layer between the intermediate layer and the second barrier layer; and a filter made of nonwoven fabric. The compostable barrier film of the first barrier layer may not be made of cellulosic material. The compostable barrier film of the second barrier layer may not be made of cellulosic material. The compostable multilayer membrane may have an Oxygen Transfer Rate (OTR) value lower than 0.5 cc/m2/day/atm. The filter may be adjacent to the second barrier layer on a side opposite to the intermediate layer.

Abstract: The present invention relates to a capsule (1) for preparing infused beverages comprising a main body (10) having a central axis (A), a first end (10a) and a second end (10b), said main body (10) comprising an axially symmetrical side wall (2) with respect to said central axis (A) and converging from the first (10a) to the second end (10b), a bottom wall (3) connected to the side wall (2) and arranged at said second end (10b), a cavity (4) containing an ingredient for the preparation of beverages, said cavity (4) being defined by said side wall (2) and by said bottom wall (3), said bottom wall (3) being openable for introducing pressurized liquid into said cavity (4), said cavity (4) having an opening (12) arranged at the first end (10a), an annular flange (14) connected to said side wall (2) at said first end (10a) and extending radially from said side wall (2) towards the outside, said flange (14) having an inner surface (14a) facing said second end (10b) and an outer surface (14b) opposite the inner surfac

Abstract: The present invention relates to a capsule for use in a machine for preparing a liquid product from soluble or extractable products by means of a pressurized extraction fluid. The capsule comprises a container body defining a closed chamber for housing the soluble or extractable product by means of a pressurized extraction fluid, said fluid being supplied through an injection element of the machine, said container body having a first base and a second base and a side wall extending along a longitudinal direction between the first base and the second base, an injection lid sealingly associated to said container body and designed to be opened to allow the introduction of said pressurized fluid into said chamber; a beverage dispensing lid sealingly associated to said container body and designed to be opened to release a beverage prepared from said product and said fluid.

Abstract: The present invention relates to a capsule for soluble or extractable products using a pressurized extraction fluid, which comprises a container body, defining a volume for housing the soluble or extractable product, having a lower base and a upper base and a side wall extending in a longitudinal direction X-X between the lower base and the upper base.

Abstract: The present invention addresses a compostable multilayer membrane (10) for cartridges containing soluble products or products adapted to be brewed by pressurized water or other fluid, comprising a first barrier layer (11) containing a compostable barrier film, a first metallization layer (12), an intermediate layer (13) containing at least one adhesive, a second barrier layer (14) containing a compostable barrier film. The compostable multilayer membrane (10) is characterized in that it comprises a layer (18) adjacent to the first barrier layer (11), on a side opposite to that upon which the metallization layer (12) has been deposited, which comprises a heat-resistant lacquer, a second metallization layer (17) disposed between the intermediate layer (13) and said second barrier layer (14), said compostable barrier film of said first barrier layer (11) and said second barrier layer (14) not being made of paper, such that said compostable multilayer membrane (10) will have an OTR value of less than 0.
