Abstract

A capsule containing hydro-soluble ( 4 ) or infusion products ( 4′ ) to obtain hot beverages characterized by the fact that the bottom wall ( 6 ) presents holes ( 7 ) especially dimensioned to allow the outflow of the process liquid and it is sealed from the outside through a film (F) removable only at the time of usage.

1 ) A capsule containing hydro-soluble ( 4 ) or infusion products ( 4 ′) to obtain hot beverages characterized by the fact that the bottom wall ( 6 ) presents holes ( 7 ) especially dimensioned to allow the outflow of the process liquid and it is sealed from the outside through a film (F) removable only at the time of usage. 
   
   
       2 ) A capsule as in  claim 1 , characterized by the fact that the upper part ( 5 ) is sealed by an external film (F″) that can be punctured or removed only at the moment of its use. 
   
   
       3 ) A capsule as in previous claims, characterized by the fact that under the upper removable film (F″) is inserted a paper filter diaphragm ( 2 ) allowing the uniform distribution of the process liquid, and avoiding the leaking of the packaged product ( 4 ,  4 ′). 
   
   
       4 ) A capsule, as previously claimed, characterized by the fact that when the products packaged in the capsule ( 1 ) are not hydro-soluble products ( 4 ) as powder milk, but are infusion products ( 4 ′) as ground coffee, on the bottom wall ( 6 ) is internally attached a paper-filter diaphragm ( 3 ) that filters the infusion withholding impurities and extending the duration of the infusion process, improving the quality of the obtained espresso.
