METHOD FOR PREPARING A BEVERAGE FROM A CAPSULE AND DEVICE THEREFOR

摘要

Procedure for making a drink uses a capsule (1) with a supple membrane (17) that has a high capacity for elastic or permanent deformation and is perforated by a series of spikes (25) on a perforator (3). The perforator surface (24) is convex in shape so that it deforms the membrane in the direction of the substance (2) in the capsule. Procedure for making a drink uses a capsule (1) with a supple membrane (17) that has a high capacity for elastic or permanent deformation and is perforated by a series of spikes (25) on a perforator (3). The perforator surface (24) is convex in shape so that it deforms the membrane in the direction of the substance (2) in the capsule. The size of the holes made by the perforator is governed by the level to which the capsule is filled or the compaction of the substance which influences the pressure on the two sides (17a, 17b) of the membrane.
