Capsule for infusion products, in particular coffee

摘要

The capsule (10) comprises a cup-shaped body (12) and a lid (14) which closes the cup- shaped body (12) superiorly. The cup-shaped body (12) comprises a side wall (16) and a bottom wall (18). The bottom wall (18) has at least one outlet opening (20) for the beverage to flow out of the capsule. The cup-shaped body (12) further comprises a retaining wall (26) defining inferiorly an intermediate compartment (22) containing the infusion product. The retaining wall (26) includes an impermeable layer (32) and is spaced from the bottom wall (18) so as to define with the latter a lower compartment (28). The impermeable layer (32) is configured to autonomously tear, due to the pressure reached in the intermediate compartment (22) following the introduction of pressurized hot water into the capsule (10). The capsule (10) further comprises a perforated and elastically deformable support disc (34) which is arranged beneath the impermeable layer (32), with a peripheral edge (34a) thereof resting on the bottom wall (18) of the capsule (10) or on a support surface placed at a distance from the bottom wall (18) of the capsule (10), and is configured to deform, by flexing towards the bottom wall (18) of the capsule (10), as a result of the flexing of the impermeable layer (32) when the pressure inside the intermediate compartment (22) increases following the introduction of pressurized hot water into the capsule (10).
