1. A recyclable container containing a substrate treatment liquid, configured for fluid connection to a fluid communication system of a substrate treatment machine, the container comprising:
(i) a reservoir containing a multi-dose stock of the substrate treatment liquid;
(ii) a container connector which is designed to be removably and fluidly connectable with a machine connector of the substrate treatment machine, said connectors together forming a container-machine connection, such that the substrate treatment liquid can controllably flow from the reservoir via the container-machine connection to said fluid communication system; and
(iii) a valve which is movable between an open and a closed position to control the flow of substrate treatment liquid from the container, said valve comprising a biasing member such that the valve is biased toward an open or closed position within a housing;
wherein the reservoir, container connector and valve comprise a recyclable plastic and that the biasing member comprises a recyclable plastic having a shore A hardness of 30-95 degrees, wherein the biasing member is under load whilst the valve is open and the substrate treatment product dispensed, and then it is unloaded (relaxed to its free length) when the valve is shut.
