Capsules for infusion products

A capsule for infusion products comprising a cup-shaped body and a lid for closing the cup-shaped body superiorly,

• wherein the cup-shaped body comprises a side wall and a bottom wall having at least one outlet opening for the infusion to flow out of the capsule, and a retaining wall defining inferiorly an intermediate compartment containing the infusion product, the retaining wall comprising an impermeable layer, which is firmly secured at a peripheral edge thereof to the cup-shaped body and which is configured to tear as a result of the increase in pressure in the intermediate compartment following the introduction of pressurized hot water into the capsule, and also being spaced from the bottom wall so as to define with the latter a lower compartment,
• wherein the capsule further comprises filtering elements configured to filter the infusion upstream of the outlet opening, and
• wherein the capsule further comprises a perforated and elastically deformable support disc which is arranged beneath the impermeable layer, with a peripheral edge thereof resting on the bottom wall of the capsule or on a support surface placed at a distance from the bottom wall of the capsule, and is configured to deform, by flexing towards the bottom wall of the capsule, as a result of the deformation of the impermeable layer when the pressure inside the intermediate compartment increases due to the introduction of pressurized hot water into the capsule, until the impermeable layer tears as a result of its deformation.
