Abstract
A method for producing a single-use capsule (1) for extraction beverages comprises the steps of: positioning a flat piece (8) of filter paper over a cup-shaped rigid body (2); joining the flat piece (8) of filter paper along at least the rim (7) of the rigid body (2); forming the piece (8) of filter paper towards the interior of the rigid body (2) and by means of plastic deformation of the piece (8) of filter paper so as to define a containment chamber (5); filling of the containment chamber (5) with a dose (D) of product; closing of the chamber (5) and of the external rigid body (2) with a sheet lid (6). This invention also relates to a machine (100) which implements said method.

A method for producing a single-use capsule (1) for beverages comprising a cup-shaped external rigid body (2) comprising a closed bottom (3) and a top opening (4) coupled with a filter extending, with a concave cross-section, into the body (2) to form a chamber (5) for containing a dose (D) of product, and a sheet lid (6) for closing the top opening (4) of the rigid body (2) along the external rim (7) of the body (2), characterised in that it comprises the following steps:
- positioning a flat piece (8) of filter over the rigid body (2);
- joining the flat piece (8) of filter paper along at least the rim (7) of the rigid body (2);
- forming the piece (8) of filter paper towards the interior of the rigid body (2) and by means of a plastic deformation of the piece (8) to define the containment chamber (5);
- filling the containment chamber (5) with a dose (D) of product;
- closing the chamber (5) and the external rigid body (2) with the sheet lid (6).
A machine for producing a single-use capsule for extraction beverages, comprising at least:
- a conveyor (9) for conveying cup-shaped external rigid bodies (2), comprising a closed bottom (3) and a top opening (4), for moving them one after another in a direction of feed (A);
- and
- feed means (10) for feeding flat filter paper and designed to position the filter paper along at least one stretch of the feed line (A);
- characterised in that the machine also comprises, along the direction of feed (A):
- cutting units (11) for cutting the filter paper to obtain a flat piece (8) of filter paper matching the top surface of the rigid body (2);
- joining means (12) for perimetrally joining the flat piece (8) of filter paper on the top opening (4) of the rigid body (2) defined by a top rim (7);
- forming means (13) for forming the flat piece (8) of filter paper joined to the rigid body (2), said forming means being positioned downstream of the joining means (12) for perimetrally joining the flat piece (8) of filter paper relative to the direction of feed (A), and acting on the flat piece (8) of filter paper so as to plastically deform the piece (8) of filter paper towards the interior of the rigid body (2) to define a chamber (5) for containing a dose (D) of product inside the rigid body (2).
