System for admixture of a material in powder or liquid form

System (1) for handling a material (8) of solid particles such as granular, flakes or powder into a fluid stream, said fluid stream being a water stream, the system comprising a container (5) enclosing the material (8), said container cooperating with an outlet (3) of a tap or faucet (4) comprising a spout having a spout outlet and at least a part of the container (5) being permeable for the fluid (9) dispensed from the (4) tap/faucet (4), said system (1) further comprising a device (2) configured to cooperate with the outlet and the container (5), said device (2) being made in a material non-permeable for the fluid (9), and said system comprising position means (6) configured to position and to sustain the container (5) in a defined relation to said device (2), said container comprising a top part (21), a bottom part (22), side parts (23), a fluid inlet and a fluid outlet, characterised in that the device is adapted to be placed in the spout outlet (32) and the fluid inlet (30) is placed in the top part of the container and the outlet (31) is placed in the oppositely placed bottom part (22) and/or lower part of the side parts (23), whereby the fluid passes through the solid particles (8) from the top to the lower part of the container (5) extracting the flavour and nutrients of the solid particles.
