Capsule with controlled opening, process and device for operating the capsule

摘要

The present invention refers to a capsule containing at least one aromatic substance for producing a beverage by means of its crossing by a pressurized fluid flow, and having at least one controlled opening element retained in a removable manner at least in one zone of the capsule facing the flow upstream and/or downstream. Said controlled opening element, by means of applying at least one certain actuation force exerted by a respective extraction device, may be displaced in at least linear or rotating fashion from an initial retaining position, that produces the airtight closure of the capsule, to at least one following position, thereby releasing at least one section of flow passageway of previously defined configuration and dimension in view of an optimized flow distribution inside said capsule.

主权项

1. A capsule containing at least one aromatic substance for production of a beverage due to a pressurized fluid flow crossing through said capsule, comprising:
at least one construction element defining a zone of the capsule facing the flow upstream, and a zone of the capsule facing the flow downstream, and a controlled opening element retained in a movable manner within a respective element fixture, in at least one of said zone facing the flow upstream and in said zone facing the flow downstream, wherein each of said controlled opening element and said respective element fixture include at least one flow passageway comprising a predetermined sized opening formed therein, and wherein said controlled opening element is configured to receive at least one actuation force that displaces said controlled opening element from an initial position (A) of retention in the respective element fixture to a following position (B) of retention in the respective element fixture, thereby moving at least one section of said flow passageway provided in said controlled opening element with respect to at least one section of said flow passageway provided in said respective element fixture, and wherein in the initial position (A) the controlled opening element blocks the flow passageway in said respective element fixture, and in the following position (B) the controlled opening element unblocks the flow passageway in said respective element fixture.
