ABSTRACT:
A device for dosing a flowing fluid including a cylindrical casing which can be opened and which has an inlet at one end and an outlet at the other. A cylindrical liner is within the casing, there being a perforated wall at the inlet end of the liner. The outlet end of the liner is partly closed by a plate fixed to the casing. A spike having a shank and a head is fixed to the plate, the head being within said liner and the shank passing through the plate. A bore passes through the shank and emerges through a conical surface of the head. There is an annular shoulder between the shank and the head. An additive cartridge comprises a bag and an element including a sleeve through which the spike passes when the cartridge is impaled on the spike. The element includes a flange for co-operation with said shoulder to prevent accidental removal of the cartridge from the spike.
