Capsule for obtaining beverages such as espresso and method for obtaining beverages such as espresso

摘要

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). A method for the production of beverages is also shown, comprising the following step: flow of water under pressure against the entry surface (6) of the capsule (1) so as to open the reduced thickness areas (3) of the entry surface (6) so as to allow the water under pressure to enter the capsule (1).

主权项

1. A capsule for obtaining beverages comprising:
a side wall, an entry surface, and one or more strengthening ribs provided on the entry surface for the entrance of water under pressure into the capsule, said side wall and said entry surface forming a containment volume for containing an infusion product, wherein said entry surface having a first thickness comprises one or more elastically reclosable reduced thickness areas relative to the first thickness so that, letting water under pressure flow against said entry surface, said one or more elastically reclosable reduced thickness areas open so as to allow water under pressure to enter the capsule and said one or more elastically reclosable reduced thickness areas are made of elastic material so that, after having been opened by a flow of water under pressure, the one or more elastically reclosable reduced thickness areas return to a closing position when the flow of water under pressure is stopped.
