Bag for a beverage preparation

Abstract

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.

1 . A bag for a beverage preparation, comprising:
 a disposable closed bag formed of a package material defining an interior of the closed bag,   a beverage preparation of a solid substance placed in the interior of the closed bag, said substance being capable of giving off components of the beverage through a water-permeable portion of the package material when the bag is infused in water for preparing a beverage, and   a supporting surface which forms a portion of the package material and 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 a wetted beverage preparation in the interior of the closed bag.   
     
     
         2 . The bag according to  claim 1 , wherein the bag comprises
 a bottom portion formed as a water-impermeable structure, side wall ( 2 ) of the bag permeable to water above the bottom portion, and   a water-impermeable area of the bottom portion extending as a collar to a given height in the direction of the side wall.   
     
     
         3 . The bag according to  claim 1 , wherein the bag comprises two suspension points which define two different inclination positions for the bag, wherein the first suspension point determines a setting position, in which the bag is suspended with the supporting surface facing downwards, and the second suspension point determines a draining position, in which the supporting surface is turned to an angle to the setting position. 
     
     
         4 . The bag according to  claim 3 , wherein the suspension points are connected by means of a suspension string. 
     
     
         5 . The bag according to  claim 3 , wherein the second suspension point defines a position, in which an edge on opposite side of the bag with respect to the location of the second suspension point is directed downwards. 
     
     
         6 . The bag according to  claim 3 , wherein the second suspension point is placed in the water-impermeable structure. 
     
     
         7 . The bag according to  claim 3 , wherein in the draining position of the bag the side wall of the bag above the bottom portion of the bag is turned to a smaller angle to the horizontal plane than in the setting position.
