Apparatusfor dosing a liquid colour formulation into polymer includes a weighing platformwhich is supported on a pair of load cellswhich are, in turn, supported on a base. A reservoircontains liquid colour formulation. A pumpis arranged to pump liquid formulation, via a tube, to an extruder or injection moulding machine. Above inletis a delivery packwhich includes a bag-in-a-box arrangement. The delivery packincludes a transfer pumpassociated with an outlet of the receptacle. A transfer pump motoris arranged to be engaged with the transfer pumpand operated so that liquid formulation can be pumped from the receptacleinto reservoiracross an air gapdefined between the transfer pumpand the inletof reservoir. There is no pipe, tube or other conduit through which liquid formulation passes on travel between delivery packand reservoir

Apparatus and method for dosing a fluid formulation into a polymeric material

Injection apparatus for injecting a liquid formulation into a molten polymer at high pressure includes a reservoir containing liquid formulation at ambient temperature and pressure which is arrange to flood-feed pump bodyof a first progressing cavity pump (pcp) (). The first pcp () is driven by motor () and is arranged to accurately meter the liquid formulation into a second pcp () which is downstream of the first pcp and is arranged to increase the pressure of the liquid formulation by 200 bar or more. Downstream of pump () is a delivery valve () arranged to control passage of liquid formulation, via outlet (), into pressurised molten polymer stream () which is present in an extruder ().

A receptacle includes a cardboard box in which is arranged a plastics container. A first securement element associated with the plastics container is positioned in a gap defined by the cardboard of the box thereby to restrict movement of the container within the box.
