Capsule for making beverages

摘要

A capsule (1) for making beverages comprises a powdered food substance, and comprises a body (2) having a lower wall (3) and a side wall (4), and a lid (6) fixed to an edge (5) of the side wall (4). Between the lid (6) and the inner surface of the body (2) there is a chamber in which a rigid or semi-rigid filter (10) is positioned, coupled at a coupling portion (14) located on the side wall (4) close to the edge (5). The filter (10) extends between a rim (12) positioned close to the lid (6) and coupled to the coupling portion (14), and a bottom portion (13) positioned close to the lower wall (3), and separates the chamber into a first compartment (15), containing the substance, delimited at least between the filter (10) and the lid (6), and into a second compartment (16) partly positioned between the side wall (4) and the filter (10), delimited between the filter (10), the lower wall (3) and the portion of side wall (4) located between the lower wall (3) and the coupling portion (14). The second compartment (16) comprises openings (11) at the part of it positioned between the filter (10) and the side wall (4).

主权项

1. A capsule for making beverages comprising at least one powdered food substance which can be extracted by passing water through it to make a beverage, comprising:
a substantially cup-shaped body which in turn comprises a lower wall and a side wall; a lid fixed to the body at an edge of the side wall located on the opposite side to the lower wall, between the lid and the inner surface of the body there also being a chamber and between a central point of the lid and a central point of the lower wall being identified a capsule axis of extension; a rigid or semi-rigid filter positioned in the chamber and coupled to the capsule body at a coupling portion which is substantially annular about the axis of extension and located on the side wall, said filter comprising openings to allow fluid communication through it;characterised in that
the filter extends between a substantially annular rim located at the top of the filter and positioned close to the capsule lid, and a bottom portion located at the bottom of the filter and positioned close to the lower wall, the coupling portion being located close to the edge of the side wall and the filter being coupled to the coupling portion substantially at the rim;and in that
the filter substantially separates the chamber into a first compartment in which the powered food substance is contained and a second compartment, said first compartment being delimited at least between the filter and the lid, and said second compartment being delimited between the filter, the lower wall and the portion of the side wall located between the lower wall and the coupling portion, at least part of the second compartment being positioned between the side wall and the filter and the second compartment extending along the side wall to the coupling portion and at least over most of the distance between the coupling portion and the lower wall measured parallel with the axis of extension, said openings being made at least at the part of the second compartment positioned between the filter and the side wall, the filter is substantially cup-shaped and includes a side portion extending between the bottom portion and the rim about the axis of extension, said openings being located at least on the side portion, the distance between the filter and the side wall at the second compartment increases proceeding towards the bottom portion, and the side portion of the filter has the structure of superposed rings, which are annular about the axis of extension and are connected to each other, each of the rings, proceeding from the rim towards the bottom portion of the filter, delimiting a respective section of the first compartment, in a plane substantially perpendicular to the axis of extension, having an area greater than that delimited by the next ring, the side portion, seen in radial section relative to the axis of extension, comprising, on the side facing towards the first compartment, a profile substantially formed by steps corresponding to said rings.
