a receptacle mounted on the support and defining a reservoir space with an open top and being configured to receive the volume of liquid in the reservoir space through the open top,
wherein the receptacle includes a flexible membrane integrally forming a base and a wall, the wall being substantially transverse to the base and having a working surface configured to spread the liquid over the treatment surface, wherein the base has a continuous surface such that liquid cannot pass through the base,
wherein the wall includes an inner portion which extends from the base to an upper end and an outer skirt portion, wherein the inner portion and skirt portion form a double-wall structure, and
wherein at least the wall is resiliently deformable so in use the working surface maintains contact with the treatment surface when spreading the liquid.
