A CAPSULE FOR THE PREPARATION OF A BEVERAGE AND A METHOD FOR MANUFACTURING SAID CAPSULE

A capsule for the preparation of a beverage in a beverage preparation device (10) and a method for manufacturing said capsule are described. The capsule comprises a cup-shaped body (1) and a cover (2) for closing the cup-shaped body (1). The cup-shaped body (1) comprises a bottom wall (4), a lateral wall (5) and an annular flange (3) for the cover (2) to seal thereon. The lateral wall (5) is made at least of a first structural layer (5A) and the bottom wall (4) is made at least of a second structural layer (4A). The cup-shaped body (1) comprises an oxygen barrier liner (14) attached to the inner surface (5C) of at least the first structural layer (5A) of the lateral wall (5). The oxygen barrier liner (14) comprises at least a polymer, preferably a biopolymer. The bottom wall (4) is suitable for being pierced by a piercing member (12) of the beverage preparation device (10). The first layer (5A) of the lateral wall (5) and the second layer (4A) of the bottom wall (4) are made of different materials: the first structural layer (5A) of the lateral wall (5) is made of cellulose pulp, and the second structural layer (4A) of the bottom wall (4) comprises between 0% and 60% of cellulose pulp and between 40% and 100% of a polymer, preferably a biopolymer.
