Disposable capsule for machines for preparing infused beverages

Abstract

A disposable capsule for use in machines for preparing infused beverages is disclosed. The capsule includes i) a cup-shaped hollow body adapted to receive a measured dose of a granulate or particulate product ii) a lid tightly fixed on a flange of the body; and iii) a distributor-collector insert. The insert stretches out axially from a base to a top of the body and has a glass-shaped portion arranged close to the top, a disk-shaped portion arranged at the base and a rod-shaped portion which connects the glass-shaped portion to the disk-shaped portion. The glass-shaped portion also has a plurality of through openings formed in a radial direction and the disk-shaped portion has a plurality of through openings formed in the axial direction.

1 . A disposable capsule for machines for preparing infused beverages, said capsule comprising:
 i) a cup-shaped hollow body adapted to receive a measured dose of a granulate or particulate product;   ii) a lid sealed on a flange of said body;   iii) a distributor-collector insert,   wherein said insert stretches out axially from a base to a top of said body and comprises a portion arranged close to said top, a disk-shaped portion arranged close to said base and a rod-shaped portion which connects said portion close to the top to said disk-shaped portion close to the base,   and wherein the portion close to the top comprises a plurality of through openings formed in a radial direction and the disk-shaped portion close to the base comprises a plurality of through openings formed in the axial direction,   and wherein   the portion close to the top is a glass-shaped portion and   the disk-shaped portion is arranged at the base.   
     
     
         2 . A capsule according to  claim 1 , wherein the glass-shaped portion of the insert further comprises a flange arranged on a top edge thereof, said flange being fixed to said lid and defining with the lid a chamber intended to receive an infusion liquid. 
     
     
         3 . A capsule according to  claim 1 , wherein the glass-shaped portion of the insert further comprises a flange on a top edge thereof, said flange being radially extended up to a peripheral wall of the body of the capsule and sealingly engaging a groove circumferentially formed therein, the glass-shaped portion, the flange and the portion of the peripheral wall arranged between the flange and the lid of the capsule defining with the lid a chamber intended to receive an infusion liquid. 
     
     
         4 . A capsule according to  claim 1 , wherein the disk-shaped portion of the insert has a frusto-conical shape. 
     
     
         5 . A capsule according to  claim 1 , wherein the disk-shaped portion of the insert has a flat shape. 
     
     
         6 . A capsule according to  claim 1 , wherein said insert further comprises a filter element, said filter element being arranged on the surface of the disk-shaped portion facing the base of the body of the capsule. 
     
     
         7 . A capsule according to  claim 1 , wherein the rod-shaped portion of the insert is made up of a first portion associated with the glass-shaped portion and of a second portion associated with the disc-shaped portion said first and second portions being configured to be assembled with each other and being telescopically fitted into one another in an operating configuration of the capsule and having respective cylindrical matching shapes. 
     
     
         8 . A capsule according to  claim 7 , wherein the first portion of the rod-shaped portion comprises a through opening formed on its bottom, and wherein the second portion of the rod-shaped portion is provided with a base formed by a wall arranged between its free end and the disk-shaped portion, the overall configuration of the rod-shaped element being such that, in use, the first portion abuts the base of the second portion, which thus serves as a stop member for the first portion. 
     
     
         9 . A capsule according to  claim 8 , wherein the base of said body has a frusto-conical shape and wherein a barrier film is fixed along the periphery of the base, the disk-shaped portion of the insert comprising a plurality of sharpened elements that protrude from the surface facing the base of the body. 
     
     
         10 . A capsule according to  claim 9 , further comprising a collector element housed in said frusto-conical base, said collector element comprising a plurality of protruding members configured to contact the barrier film ( 300 ), a plurality of through openings formed in the axial direction and an appendix having a hollow tubular shape, said appendix protruding axially towards the frusto-conical base and engaging an outlet opening formed therein.
