| 1. A cartridge (1; 200) for coffee or soluble products for the production of a beverage, comprising:
a container (2) designed to contain coffee or soluble product,
a lid (6) set on the top of the container so as to define an upper wall through which hot water under pressure enters the container
(2) in order to produce the beverage, and
a filter (4) designed to be positioned inside said container (2) above a bottom wall (20) of the container through which the beverage leaves,
wherein
said bottom wall (20) of the container has at least one breakable portion (28) designed to break when the liquid inside the cartridge reaches a pre-set pressure, so as to form at least one aperture (130) to allow the beverage to be extracted from the cartridge (1), said at least one breakable portion (28) being obtained by means of grooves (27) formed in a weakened portion (22) of the bottom wall (20) of the cartridge (1) so that at least one breakable portion (28) is thinner than the weakened portion (22).
