A method for preparing a drink by passing hot water in a capsule (1), in which first at least one cut (10) extending in a linear fashion is made through the second wall (3) of the capsule (1), substantially without removing material from it. The adjacent portions (11) of the second wall (3) delimiti
A method for preparing a drink by passing hot water in a capsule (1), in which first at least one cut (10) extending in a linear fashion is made through the second wall (3) of the capsule (1), substantially without removing material from it. The adjacent portions (11) of the second wall (3) delimiting the cut (10) are then allowed to draw near one another again if necessary, then, by injecting hot water into the capsule, the internal pressure in the capsule is increased to cause at least partial expulsion of the air contained in it substantially without dispensing the liquid, and, then, by deformation of the second wall (3), the adjacent portions (11) delimiting the cut (10) are moved away from one another, allowing the drink to flow out. The invention also relates to an apparatus and a capsule for implementing this method.

1. A method for preparing a drink by passing hot water in a capsule (1) which has a first wall (2) and an unpierced second wall (3) and which contains a substance (5) to be extracted, the method being implemented by an apparatus for preparing a drink and comprising the operating steps of: creating a
1. A method for preparing a drink by passing hot water in a capsule (1) which has a first wall (2) and an unpierced second wall (3) and which contains a substance (5) to be extracted, the method being implemented by an apparatus for preparing a drink and comprising the operating steps of: creating a first opening through the first wall (2) of the capsule (1);creating a second opening (7) through the second wall (3) of the capsule (1);injecting hot water into the capsule (1) through the first opening; andmaking the drink flow out through the second opening (7); the method being characterised in that the step of creating the second opening (7) in turn comprises the operating steps of: making at least one cut (10) extending in a linear fashion through the second wall (3) of the capsule (1), substantially without removing material from the second wall (3), said cut (10) being delimited by two adjacent portions (11) of the second wall (3), the cut (10) being made using cutting means (35);removing the cutting means (35) from the cut (10) and allowing the adjacent portions (11) of the second wall (3), which delimit the cut (10), to draw near one another again; andafter said drawing near again and by means of said injection of hot water, increasing the internal pressure in the capsule (1) to cause, in succession: at least partial expulsion of the air contained in the capsule without substantial dispensing of the drink; andby means of an outward deformation of the second wall (3) at least at said adjacent portions (11), a movement away from one another by the adjacent portions (11) delimiting the cut (10), allowing the drink to flow out. 2. The method according to claim 1, characterised in that the step of the adjacent portions (11) drawing near one another again occurs before said injection step. 3. The method according to claim 1, characterised in that the step of the adjacent portions (11) drawing near one another again involves their drawing near one another again being caused by said injection step. 4. The method according to claim 1, characterised in that the step of the adjacent portions drawing near one another again is carried out in such a way that, following said step, the cut (10) has a size and/or shape such that it allows the passage of air. 5. The method according to claim 4, characterised in that the step of the adjacent portions drawing near one another again is carried out in such a way that, following said step, the cut (10) has a size and/or shape such that it substantially prevents the passage of liquid. 6. The method according to claim 4, characterised in that the step of the adjacent portions drawing near one another again is carried out in such a way that, following said step, the cut (10) has a size and/or shape such that it substantially prevents the passage of particles of the substance (5) to be extracted which are carried to the cut (10) by the water injected into the capsule (1), the passage of liquid through the cut (10) in this way being prevented by the cut (10) operating in conjunction with the particles of the substance (5) accumulated at the cut. 7. The method according to claim 6, characterised in that it also comprises a step of blocking the cut (10) using particles of the substance (5) to be extracted carried to the cut (10) by the water injected into the capsule (1). 8. The method according to claim 7, characterised in that the blocking step takes place at the start of the injection step, before deformation of the second wall (3) allows drink dispensing. 9. The method according to claim 8, characterised in that, during the step of deformation of the second wall (3), there is also a step of expulsion of the particles. 10. The method according to claim 1, characterised in that the injection step is divided into a first sub-step during which the internal pressure in the capsule (1) substantially increases without deformation of the second wall (3) and without drink dispensing, and into a second sub-step during which the pressure is further increased and causes the deformation of the second wall (3) and consequent drink dispensing. 11. The method according to claim 1, characterised in that the step of deformation of the second wall (3) involves an elastic or permanent deformation of the wall. 12. The method according to claim 1, characterised in that the step of making at least one cut (10) involves making the cut (10) so that it extends in a straight fashion. 13. The method according to claim 1, characterised in that the step of making at least one cut (10) involves making the cut (10) so that it extends in a curved fashion. 14. The method according to claim 1, characterised in that the step of making the cut (10) is carried out without affecting what is contained in the capsule (1). 15. The method according to claim 1, characterised in that the cut (10) is made with a length of between 2 and 6 mm. 16. The method according to claim 1, characterised in that during the step of making the cut (10) a plurality of cuts are made, each delimited by two adjacent portions (11), and in that it comprises, for each cut (10) said steps of the adjacent portions (11) delimiting the cut drawing near one another again and moving away from one another. 17. The method according to claim 16, characterised in that said cuts are made in such a way that each is in a different zone of the second wall (3). 18. The method according to claim 16, characterised in that at least some of said cuts intersect. 19. The method according to claim 1, characterised in that the step of deformation of the second wall (3) involves only part of the second wall (3) at the cut (10). 20. The method according to claim 1, characterised in that the step of deformation of the second wall (3) involves the entire second wall (3).
