A capsule for making a beverage, containing a food substance, which allows the beverage to be made by passing a water flow through the food substance, wherein said capsule comprises: a main body which is substantially cup-shaped and which has a lateral wall and a bottom wall, the lateral wall extending between a first edge, which defines an infeed opening, and a second edge, and the bottom wall being connected to the second edge and closing the main body at said second edge; and an upper film, fixed to the main body at the first edge; wherein: one of either the bottom wall or the upper film is configured to constitute an infeed wall for the water into the capsule and the other, of either the bottom wall or the upper film is configured to constitute an outfeed wall for the beverage from the capsule; a water flow distributing unit is placed inside the main body, said water flow distributing unit being positioned between the infeed wall and the food substance, and being permeable for the water flow; characterised in that it also comprises a reinforcing element which is a separate element from the water flow distributing unit, and is placed inside the main body between the infeed wall and the water flow distributing unit, said reinforcing element being configured to limit, in use, a deformation of the water flow distributing unit towards the infeed wall. a main body which is substantially cup-shaped and which has a lateral wall and a bottom wall, the lateral wall extending between a first edge, which defines an infeed opening, and a second edge, and the bottom wall being connected to the second edge and closing the main body at said second edge; and an upper film, fixed to the main body at the first edge; wherein: one of either the bottom wall or the upper film is configured to constitute an infeed wall for the water into the capsule and the other, of either the bottom wall or the upper film is configured to constitute an outfeed wall for the beverage from the capsule; a water flow distributing unit is placed inside the main body, said water flow distributing unit being positioned between the infeed wall and the food substance, and being permeable for the water flow; characterised in that it also comprises a reinforcing element which is a separate element from the water flow distributing unit, and is placed inside the main body between the infeed wall and the water flow distributing unit, said reinforcing element being configured to limit, in use, a deformation of the water flow distributing unit towards the infeed wall. one of either the bottom wall or the upper film is configured to constitute an infeed wall for the water into the capsule and the other, of either the bottom wall or the upper film is configured to constitute an outfeed wall for the beverage from the capsule; a water flow distributing unit is placed inside the main body, said water flow distributing unit being positioned between the infeed wall and the food substance, and being permeable for the water flow; characterised in that it also comprises a reinforcing element which is a separate element from the water flow distributing unit, and is placed inside the main body between the infeed wall and the water flow distributing unit, said reinforcing element being configured to limit, in use, a deformation of the water flow distributing unit towards the infeed wall.
