Single use filtering capsule for the creation of an alimentary infusion

摘要

A single-use filtering capsule for producing an alimentary infusion includes a casing inside which is positioned a filtering sachet containing an aromatic essence. The sachet is perimetrally fixed to the casing to separate two base extremities of the casing. A first perforable closure element allows the access of water to the aromatic essence. The first closure element is attached in closure of a first base extremity of the casing to which the sachet directs the inner side, a second closure element of a second base extremity of the casing to which the sachet directs the outer side. The capsule also includes dissociable member between the second closure element and the second base extremity of the casing, and gripping member for the second closure element for its dissociation from the second base extremity of the casing before the positioning of the capsule in an infusion apparatus.

主权项

1. A method for utilizing a single-use filtering capsule for producing an alimentary infusion, comprising:
providing a casing having a first base extremity on one side and a second base extremity on another side; providing a filtering sachet containing an aromatic essence positioned inside the casing, said sachet being perimetrally fixed to said casing in such a way as to separate the first and second base extremities of said casing, providing a first perforable closure element to allow access of water to said aromatic essence, said first closure element being attached to the casing to enclose the first base extremity of said casing, providing a second closure element for enclosing the second base extremity of said casing, providing a dissociable jointing member between said second closure element and said second base extremity of said casing for allowing the second closure element to be removed from the casing, the second closure element creating a sealed first condition of the capsule when covering the second base extremity where the second base extremity of the casing is sealed, and an open second condition when removed from the casing wherein an interior of the casing at the second base extremity is substantially entirely open to an exterior of the casing, and providing a gripping member attached to the second closure element for removing the second closure element from said second base extremity of said casing to place the capsule in the open second condition before positioning said capsule in an infusion apparatus, positioning the sachet in a collapsed condition inside said casing when the capsule is in the sealed first condition such that a base portion of said sachet rests on said second closure element, and when the capsule is in the open second condition, expanding the sachet from the collapsed condition to extend externally of the casing to increase a usable filtering surface of the sachet in the open second condition.
