CAPSULE FOR PREPARATION OF HOT BEVERAGE, METHOD AND APPARATUS ADAPTED FOR PREPARING A BEVERAGE FROM SUCH A CAPSULE

摘要

The invention relates to a capsule (10) for the preparation of a beverage obtained by supplying hot water within the capsule (10) under pressure and releasing the beverage from the capsule; said capsule (10) comprising a food substance therein, a first surface (12) adapted to be traversed by a flow of water entering the capsule, a second surface (17) adapted to be traversed by a flow of beverage existing the capsule, wherein the second surface (17) is adapted to deform outwardly upon action of the inside water pressure thereon and wherein said surface (17) comprises at least one opening member (20) capable of deforming inwards the capsule (10) upon a mechanical reaction force applied from outside onto the closure member (20) as a result of the deformation of said second surface (17) due to the build-up of the inside pressure.
