In the interior of a disposable closed bag formed of a package material, a beverage preparation of a solid substance is placed, the substance being capable of giving off components of the beverage through the water-permeable packaging material when the bag is infused in water for preparing the beverage. On part of the package material the bag includes a supporting surface which is formed as a water-impermeable structure having an upward dimension as a collar of a given height, for preventing water from leaking out from the wetted beverage preparation in the bag. |
