Flexible sealed Cartridge, which is extracted by pressure and containing the substance for preparing a Beverage chosen and formed by two plates, where the Fluid is chosen.

摘要

The present Invention relates to a flexible sealed cartridge designed to be extracted under pressure, which contains a substance for preparing a BeverageThat is a First and second sheet circularOval or polygonal Leave between them a Space for the substance between the sheets are welded together around its PeripheryThe first film being made of a material selected from Filter Paper, nonwoven material and a semirigid material andThe second layer being made of a material selected from Filter Paper.A Nonwoven material and a composite where the first layer is such that allows Water to pass through an atmospheric pressure or by Drilling means perforLove and the second sheet is such that allows Water to pass through it only if it reaches a pressure of between 0.1 and 3 bars during extraction from the cartridge.
