Capsule For The Preparation Of Infusion And Soluble Beverages

Abstract

A capsule (1) for the preparation of infused or soluble beverages comprises: a cup (2); a cover (6); a bottom (3) with an opening (31) for the outflow of the infused beverage; a base (33) with internal reliefs (310, 320, 330, 340, 350, 360) devoid of puncture elements. The capsule comprises internally a closing disc (5) permanently fixed to the inner reliefs (320, 330, 340, 360) and composed of at least two distinct portions (51, 52), joined together in an at least partially releasable manner. The capsule is characterized in that the opening for the outflow of the infused beverage occurs as a result of the deformation of the disc (5) by the pressure exerted by the fluid inside the capsule (1), to determine a separation between the portions (51, 52) that comprise the disc (5), a separation that opens a passage for the outflow of the infused liquid.

1 . A capsule for preparing infused or soluble beverages, comprising:
 a cup suitable to define an inner volume for the containment of at least one substance to be infused or dissolved, said cup being closed above by a cover, said cup being provided with a bottom, provided with an opening for the outflow of the infused beverage, and a base provided with reliefs devoid of cutting or puncture elements;   a disc, placed inside of the cup and suitable to seal the capsule below, permanently fixed on the reliefs of the base;   characterized in that said disc is composed of at least two distinct portions joined together in a manner at least partially releasable,   and in that the opening of the capsule for the outflow of the infused beverage occurs as a result of the deformation of the disc by the pressure exerted by the fluid inside the capsule, deformation that determines a separation between the portions that compose the disc, separation that opens a passage for the outflow of the infused liquid.   
     
     
         2 . The capsule according to  claim 1 , wherein the deformation of the disc determines, at least in correspondence of a compartment provided in the base of the capsule, at least one crease suitable to define a passage, between the portions that compose the disc, for the outflow of the infused beverage. 
     
     
         3 . The capsule according to  claim 1 , wherein the portions that compose the disc are joined together in an area of overlap by means of a weak lacquer to yield, allowing the at least partial detachment between the portions that compose the disc. 
     
     
         4 . The capsule according to  claim 3 , wherein the area of overlap of the portions that compose the disc is placed in correspondence of a compartment made in the base in such a way that the disc is deformed at the area of overlap. 
     
     
         5 . The capsule according to  claim 4 , wherein the compartment is an annular groove, realized in the base between an outer edge and a labyrinth, suitable to house, without obstructing it, the deformation of the disc when the pressure exerted by the fluid inside the capsule reaches a certain opening threshold level. 
     
     
         6 . The capsule according to  claim 4 , wherein the compartment is a recess, defined between a pair of adjacent reliefs suitable to house, without obstructing it, the deformation of the disc when the pressure exerted by the fluid inside the capsule reaches a certain opening threshold level. 
     
     
         7 . The capsule according to  claim 6 , wherein the disc is supported, without being fixed, on the reliefs suitable to maintain lifted the disc in deformation phase in such a way as to provide a free path for the outflow of the infused beverage to the outside of the capsule. 
     
     
         8 . The capsule according to  claim 1 , wherein the disc is composed of an outer portion in the form of a ring that surrounds an inner portion in disc form, and wherein the inner edge of the ring that realizes the outer portion is superimposed on the outer edge of the disc that realizes the inner portion. 
     
     
         9 . The capsule according to claim  1 , wherein the disc is permanently fixed to the base by a lacquer suitable to prevent the detachment or separation of the sealing disc from the reliefs. 
     
     
         10 . The capsule according to  claim 1 , wherein the reliefs on which the disc is fixed are at least one outer edge and a labyrinth portion. 
     
     
         11 . A method of preparing an infused beverage from a capsule, according to  claim 1 , wherein a pressurized fluid is inserted, characterized in that, when the pressure exerted by the fluid inside a closed chamber defined in the cup between the cover and the disc reaches a certain threshold level, the opening of the capsule to allow the outflow of the infused beverage is obtained by deformation of the disc by the pressure, deformation that determines a separation, at least partial, of the portions that compose the disc in such a way as to reduce the sealing effect previously provided by the disc itself. 
     
     
         12 . The method of preparing an infused beverage, according to  claim 11 , wherein the deformation of the disc determines, at least at one compartment provided in the base of the capsule, at least one crease suitable to define a passage between the portions that compose the disc for the outflow of the infused beverage.
