The present invention provides a pack in the form of a flexible cartridge, which may be open or closed, for the preparation of a beverage. The pack is specially adapted to an extraction machine, e.g., an espresso machine, which is operating by an extraction liquid under pressure. The pack consists of a body, which may be in the form of one having a cavity which is provided with a rim and which contains a powder-form substance for the preparation of the beverage. The pack is closed by a membrane which is applied to the rim of the body. The pack further includes a complementary stiffening element which is independent of the body. The stiffening element may be the membrane. The body may be of a shape which is configured so that the extraction liquid is able to circulate through a layer of the powder-form substance during the extraction through an exact adaption of the cavity to the extraction machine.
