Abstract: A method is provided for the production of beverages by means of a capsule comprising a side wall (5), an entry surface (6) for the entrance of water under pressure into the capsule (1), the side wall (5) and the entry surface (6) forming the containment volume (V) for containing the infusion or soluble product (P), and the entry surface (6) comprising one or more reduced thickness areas (3), wherein the method comprises the following steps: pushing the entry surface (6) of the capsule (1) using pushing means (S) and injecting a flux of water under pressure so as to open the one or more reduced thickness areas (3) of the entry surface (6) so as to allow the water under pressure to enter the capsule (1).

Abstract: A capsule (1) for obtaining beverages is shown, comprising a side wall (5) and an entry surface (6) for the entrance of water under pressure into the capsule (1), wherein the side wall (5) and the entry surface (6) form the containment volume (V) for containing the infusion product (P). The entry surface (6) comprises one or more reduced thickness areas (3) so that, letting water under pressure flow against the entry surface (6), the one or more reduced thickness areas (3) open, so as to allow water under pressure to enter the capsule (1). The capsule (1) may further comprise one or more strengthening ribs (4) provided on the entry surface (6) so as to strengthen the entry surface (6) and simplify the opening of the reduced thickness areas (3) when water under pressure flows against the entry surface (6).

Abstract: Machine for packaging in capsules, also in a vacuum and/or in a controlled atmosphere, characterized by the fact that a cylindrical wheel (G) with horizontal axis (R), peripherally provided with rows (S) of cavities (A), parallel to said axis (R) and angularly equally distanced by the step (P), preset to be interchangeably equipped with molds (F,-F?) having different formats and geometrically congruent to the format of the capsules to be used (C; C).

Abstract: A combined device to feed and compact preset doses of ground coffee or other similar substances includes the combination of two operating devices, the first operating device including a measuring screw in an upright position, the second operating device including a compacting piston in an oblique position that is arranged perpendicular to concavities which are geometrically congruent with the morphology of the doses to be compacted inside dies located on a polygonal conveyer.

Abstract: Combined device to feed and compact preset doses of ground coffee or other similar substances including the combination of two operating devices (A, B): the first equipment (A) consisting of a measuring screw (1) in upright position, the second equipment (B) consisting of a compacting piston (2, 2?) in oblique position that stands perpendicular to the lying concavities (5), which are geometrically congruent with the morphology of the doses to be compacted inside the dies (4) located on a polygonal conveyer (P).

Abstract: A filter paper pod packaging machine is disclosed which includes a polygonal prismatic wheel with a horizontal axis for intermittently rotating the wheel, each flat face of the prismatic wheel directly incorporating at least one recess matching size and shape of pods to be produced, wherein a first web of filter paper, fed from a spool and overlaid by a second web of filter paper fed from another spool, is wrapped around the flat faces of the polygonal prismatic wheel, and wherein a series of cuts are made by a cutting device in the first web of filter paper in appropriate positions around a central zone corresponding to the at least one recess impressed in the prismatic wheel.

Abstract: A filter pod for portions of compacted coffee, wherein a shape of a pod is asymmetrical in relation to a sealing plane of a circular peripheral zone and a central part is coplanar with the plane.

Abstract: A filter paper pod packaging machine characterised by the fact that it comprises a polygonal prismatic wheel (P) with an intermittently rotating horizontal axis (R), each flat face (L) of the prism (P) directly incorporating at least one recess (G) matching the size and shape of the pods to be produced.
