         6 . Biodegradable container ( 1 ) according to  claim 1 , characterized in that said external reinforcing means ( 4 ) are realized using biodegradable gauze, said gauze containing the expansion of said side wall ( 22 ), and/or said base ( 21 ), and/or said upper part ( 3 ), during the injection of said pressurized fluid in said biodegradable container ( 1 ). 
     
     
         7 . Biodegradable container ( 1 ) according to  claim 1 , characterized in that said external reinforcing means ( 4 ) are comprised of a biodegradable sock, said sock containing the expansion of said side wall ( 22 ), and/or said base ( 21 ), and/or said upper part ( 3 ), during the injection of said pressurized fluid solution in said biodegradable container ( 1 ). 
     
     
         8 . Biodegradable container ( 1 ) according to  claim 1 , characterized in that said side wall ( 22 ) has a plurality of longitudinal folds ( 20 ). 
     
     
         9 . Biodegradable container ( 1 ) according to  claim 1 , characterized in that said body ( 2 ) has been subjected to a grease and waterproofing treatment on the inner surface, and/or external surface. 
     
     
         10 . Biodegradable container ( 1 ) according to  claim 1 , characterized in that said base ( 21 ) has a plurality of holes ( 5 ) for administration said beverage during the injection of said pressurized fluid solution in said container ( 1 ). 
     
     
         11 . Biodegradable container ( 1 ) according to  claim 8 , characterized in that it comprises a biodegradable bottom filter ( 24 ), arranged inside said body ( 2 ) and in proximity to said base ( 21 ), for filtering said beverage and prevent the leakage of said preparation during the injection of said pressurized fluid solution in said biodegradable container ( 1 ). 
     
     
         12 . Biodegradable container ( 1 ) according to  claim 1 , characterized in that it comprises a biodegradable end plate ( 6 ) arranged internally or externally to said body ( 2 ) and in proximity to said base ( 21 ), said bottom ( 6 ) being configured to improve the mechanical strength of said base ( 21 ) and to adjust the amount of said preparation insertable within said body ( 2 ) by reducing, or increasing, its thickness, so as to reduce, or to increase, the net volume of said body ( 2 ).
