Capsule intended for receiving a substance for preparing a beverage

Abstract

The invention relates to a capsule (1) for receiving a substance for preparing a beverage, said capsule comprising a body having a side wall (2) bordered on either side by a base (3) and by a rim (4) surrounding an opening (5) in said body, the body being formed by moulding a cellulose pulp, and the side wall (2) of said body being covered with a sealing label (18).

         3 . Capsule ( 1 ) according to  claim 2 , characterized in that the cellulose-based layer comprises MFC microfibrillated cellulose. 
     
     
         4 . Capsule ( 1 ) according to  claim 1 , characterized in that it has an oxygen transmission rate of less than 10 cm 3 /m 2 ·day·atm, according to ASTM D3985 standard. 
     
     
         5 . Capsule ( 1 ) according to  claim 4 , characterized in that the oxygen transmission rate is at most 5 cm 3 /m 2 ·day·atm, and in particular less than 1 cm 3 /m 2 ·day·atm, according to ASTM D3985 standard. 
     
     
         6 . Capsule ( 1 ) according to  claim 1 , characterized in that it has a water vapor transmission rate that is less than 60 g/m 2 ·24 h, measured according to ASTM E96 standard. 
     
     
         7 . Capsule ( 1 ) according to  claim 6 , characterized in that the water vapor transmission rate is less than 10 g/m 2 ·24 h, measured according to ASTM E96 standard. 
     
     
         8 . Capsule ( 1 ) according to  claim 7 , characterized in that the sealing label ( 18 ) has been treated to improve its resistance to moisture. 
     
     
         9 . Capsule ( 1 ) according to  claim 1 , characterized in that a sealing label ( 18 ) covers the inside and/or outside of the side wall ( 2 ). 
     
     
         10 . Capsule ( 1 ) according to  claim 1 , characterized in that the sealing label ( 18 ) comprises a sealing layer on the side wall ( 2 ). 
     
     
         11 . Capsule ( 1 ) according to  claim 1 , characterized in that at least one, and in particular both, of the body of the capsule ( 1 ) and the sealing label ( 18 ) is biodegradable and/or compostable. 
     
     
         12 . Capsule ( 1 ) according to  claim 1 , characterized in that the sealing label ( 18 ) is associated with the side wall ( 2 ) during or after molding of the body according to an IML process. 
     
     
         13 . A capsule ( 1 ) according to  claim 1 , characterized in that the body is formed by dry-molding a web of cellulose pulp or by wet-molding a paste comprising cellulose pulp suspended in water. 
     
     
         14 . Capsule ( 1 ) according to  claim 1 , characterized in that the rim ( 4 ) of the capsule ( 1 ) is fitted with a sealing ring ( 30 ), in particular made from a cellulose material. 
     
     
         15 . Capsule ( 1 ) according to  claim 1 , characterized in that the base ( 3 ) comprises a lower opening ( 6 ) covered by a lower lid ( 17 ), in particular made from the same sealing film ( 12 ) as the label ( 18 ).
